7/2 Does it make sense to run NFS without NIS/NIS+? I've heard that file
permissions won't work if you're running NFS w/o NIS.
\_ nfs can run perfectly fine w/o NIS... thers not dependancy
either way.. the file perm shit is dumb and wrong or you badly
misunderstood... blah why do i post in the motd? -shac
\_ It's good that you post on the motd. Not the dumbass posters
who haven't figured out how to google.
\_ NIS is not required to run NFS but you still have to come up with
a way to synchronize the UID's and login names on all machines
accessing NFS file systems if you care about file ownership.
Here are some possible ways of doing this:
1) rebuild the /etc/passwd and /etc/group files on all of your hosts
(using the default portion of the file that came with the OS and
the site added entries)
2) use NIS.
3) use LDAP
DON'T use NIS+ as it has been EOLed in future solaris releases.
\_ http://wwws.sun.com/software/solaris/faqs/nisplus.html
\_ OP here. Sorry for the dumbass question. My problem was that I
didn't realize that root has *less* access than other users by
default. This is a good url:
http://www.ebsinc.com/solaris/network/nfs.html
\_ There's a good reason for it. For those too lazy to read the
URL, I assume it's going to say that root is usually mapped to
'nobody' because otherwise you're in the situation where someone
else can plug their box into your network. They're suddenly root
on all your nfs shares. Bad news.
\_ as opposed to being able to su to any user on your NFS
shares--not a whole lot of difference. If you're exporting
NFS to people you don't trust, you've already lost. -tom
\_ It's not about people, it's about physical access to
the network. NFS wasn't designed to be secure but at
least they can't trojan system binaries as root, only
user owned files. This is an important difference.
Security isn't all or nothing. Layers, son, layers.
\_ uh, you're exporting system binaries on writable
filesystems via NFS? you need more than layers. -tom
\_ FYI, robust NFS implementations support strong
authentication methods including kerberos 5.
Unfortunately, Linux NFS client doesn't support
any of that fancy authentication stuff so you
must choose between Linux and security..
\_ Uh, you've never used a dickless client? i have
\_ Did you miss the part about "writable
filesystems"? A diskless client doesn't need
to be able to write to its /usr partition.
If you allow this, then you're an accident
waiting to happen. --scotsman
\_ Nope. Your call. Not my problem. You'll
find out the hard way one day.

7/2 ufsdumper guy here. While I'm at it, I was wondering what sort of
dumping schedule do people use? 0 5 5 5 3? 0 5 5 5 5? 0 0 0 0 0? Also,
how do you backup multiple partitions with one fell swoop? I've been
reading around on google but there is a lot of conflicting advice.
\_ It depends. How big are your backups, how important are they,
how much do they change, how long can your system be down if
you need to recover from tape, how quick do you need to be able
to recover a file from a backup?
\_ What about the multiple partitions part?
\_ You just dump them sequentially to a NONREWINDING tape device. |

6/28 I have been repeatedly warned *not* to write shell scripts in
csh/tcsh. Is there any validity to these warnings? If so, why?
\_ Warned by? I write all my personal stuff in whatever the fuck I
want (csh/tcsh/perl). I write anything for init.d in /bin/sh
because /bin/sh should always work so the scripts are 100%
guaranteed portable. (heh). /bin/sh pretty much sucks and has
near-zero useful features but it's there.
\_ Instead of posting your question to the motd try putting it
to google. http://www.faqs.org/faqs/unix-faq/shell/csh-whynot
is the classic article that explains why it's not a great idea.
\_ For starters let's note this was written in 1996. A lot of the
bugs he's picking on aren't out there anymore. A lot of the
examples he's using are a bit contrived. I agree csh is not the
best thing to write in if you're going to stick it in /etc/init.d
or write a large script that does something important but for a
quick hack, why not? It's there, you know it, use it and throw
it out. Anything longer than 5 or 10 lines is probably a Perl
job anyway. /bin/sh for /etc/init.d, tcsh for fun, Perl for
real work. Just one man's world view.
\_ When are you people going to move to Ruby? Perl sucks.
\_ When Ruby has something that looks like CPAN so I don't
have to reinvent the wheel everytime I want to do something
interesting. I started Perl at 4.015. Lemme know when
Ruby is as useful as Perl was 5+ years ago.
\_ CPAN ugh. That is the worst thing to happen to perl
with the possible exception of the stupid OO crap.
Perl 4 was the last great perl, it had everything that
was missing from Perl 3 without any of the messy
non-sense of Perl 5 (about the only thing that Perl 5
add that is of any value is my).
\_ CPAN is bad uh how? And Perl5 added real structures
to the language making it much more useful. If all
you wanted was sed/awk, use sed/awk. Some of us are
too busy to reinvent the wheel or fucking around with
the broken data structures in Perl4.
\_ It was written in the 80s
\_ Even more so then. The date inside the URL said 96.
\_ It's just as relevant now. csh still can't do basic
stuff like redirect STDOUT and STDERR to different
places. It's a fine login shell, but it sucks for
programming. -tom
\_ Uhm, on that point in particular, you're wrong:
(command >stdoutgoeshere) >&stderrgoeshere
(admittedly, it can't, say, juxtapose the two, but
that's not needed too often) -alexf
\_ Why would anyone want to use (t)csh in a world
where ksh and bash exist?
Who uses ksh? _/
\_ Because bash is broken and stupid?
\_ uh... % ( some-command > someplace ) >& other-place
\_ I've never wanted to do the obscure shit he's talking
about csh not supporting. That's what perl is for
anyway. /bin/sh and perl covers everything.
\_ if /bin/sh and perl covers everything, why are
you programming in csh?
And really, it's pathetic that csh can't handle
trivial, obvious syntax like:
"if ( "$foo" == "bar" )". You run into shit like
that all the time with csh. -tom
\- writing stuff in csh to me is like using
vi for quick edits ... no matter how quick
or trivial you think it will be, about
half the time you get started doing
something more involved and regret not
starting out doing it right ... however
if you want an objective list of drawbacks
and gotchas in csh, that is a decent list.
when it comes to tcsh there are some bugs,
but everything has bugs ... those things
in the famous doc are mostly design flaws.
if csh works you you, do what you want.
a very imporant piece of "code" at lbl
consists of 3024 lines of csh ... it was
supposed to be a 20 line program.

6/10 A while ago there was so thread about linux clients and solaris
nfs. Today i found out that the default nfs packet size on 7.3
(redhat) is 32k not the old linux 8k. This causes clients to pound
on our nfs server. Dunno if it helps.
\_ from mount_nfs(1M)
rsize=n
Set the read buffer size to n bytes. The
default value is 32768 when using Version 3 of
the NFS protocol. The default can be negotiated
down if the server prefers a smaller transfer
size. When using Version 2, the default value is 8192.

sci-fi. -tom
\_ if you don't want to read hacks, don't read sci-fi. -!tom
\_ Clarke wasn't a hack in his earlier days (_2001_, _Childhood's
End_, etc.), but he's since taken to the senile dementia/"I
need the money" path trailblazed by other classic SF authors
(Azimov, Heinlein, et. al.) of cranking out low-to-no-quality
books, knowing that a certain group of people will buy them
just because they have his holy name on the cover. As for
authors I'd recommend in the SF/F arena: Iain M. Banks, John
Brunner, Lois McMaster Bujold, Philip K. Dick, Barry Hughart,
Cyril Kornbluth, Johnathan Lethem, Tim Powers, Kim Stanley
Robinson, Clifford Simak, Neal Stephenson, Connie Willis,

5/15 My boss wants me to track what websites a user visits. The user is
smart enough to delete their history every time they log out (tweakui?)
Any recommendations for UNIX/NT software to do this?
\_ You can use a network snooper but I question what will be
accomplish by tracking what websites your own workers visit.
\_ There could be the case of the person visiting inappropriate
sites. However, in this case, the person (a secretary) tells
everyone that she has way too much work to do, but all the other
secretaries say that she just surfs the web all day.
\_ When installing a network snooper, where do you put it? Doesn't
it depend on whether the user is connected to a switch or a hub?
\_ Yes a snooper won't work on a switched lan. A alternate soln.
if you don't want use a caching proxy is to have your fw log
all outbound http and ftp requests and then translate that to
web sites. The problem with this is that you won't be able
to catch request made to services like anonymizer.
\_ Set up a caching proxy (eg. squid) and run it in transparent
mode (your fw/router redirects port 80, 21, etc to the cache)
and turn on max logging. You need to use transparent mode so
that your users can't circumvent the cache and screw up your
information gathering.
Use perl to grok the cache's log files and generate a list of
urls (or sites) per ip. Now use the dhcp server's log files to
map IP to NIC and therefore to individual client systems and
users (I'm assuming that most of your clients are mac/win boxes
and have only one user). This should give you all the information
you need and more.
\_ Thanks! We have a cache (Symantec i-gear), but the user wasn't
using it. I'll investigate how to get our router (no firewall)
to forward requests.
\_ One possible way is the set up the dhcp server to specify
the cache as the default router for the mac in question.
Then you setup the cache to re-route all traffic (except
for http traffic, which it handles) to the real rotuer.
\_ currently, we're still on static ip's/routes, but that's
something i'll look into
\_ If she is not smart enough to also clear the disk cache, you can go
to the cache directories and look at the content. E.g. on NT,
However, I think a better solution is to just keep track of her
%USERPROFILE%\Temporary Internet Files\Content.IE5\ for IE and
%SystemDrive%\Program Files\Netscape\Users\%USERNAME%\Cache\ for
Netscape; for Unix, ~/.netscape/cache for Netscape. You might not
know which URLs she visited, but at least you can see the content
of the pages. Note that for IE some of the dirs and files are
marked hidden or system, so you have to do "dir /a" to see them.
However, I think the better solution is to just keep track of her
activity at the proxy server.
\_ Be careful of what you and your boss are doing. Unless it's
in your company policy, you shouldn't do this. Your coworkers
can sue the company for this tactic.
can sue the company for this tactic. If you're going to do this
you better adopt a policy for this and have everyone in the company
be aware of and agreeable to it.
\_ Double check with your company's specific policy, but at
most places the company owns the machine and all files on it
if it is a work machine, and the company is allowed to
access it whenever it wants.
\_ if your company is going to do that, make sure it's in the
policy. "Company owns everything" is too vague. A good
lawyer will defeat that. You can not do it in way it single
out an individual or in anyway showing bias.
\- if the person you are trying to track is stupid, you can
use dug song's software ... that will basically sniff the
net, extract the urls and feed them to a netscape you run
so you more or less can watch the secretary "over his/her
shoulder". however really you probably want timestamped
logs, in which case just get tcpdump the port 80 traffic.
getting the urls in addition to dst addr is a little more
work but pretty simple. BRO can do this. --psb |

5/7 So how does /csua/bin/me record my identity?
\_ It doesn't. people are stupid.

Duh.
\_ ...As opposed to editing the file in vi, finding that it's

\_ fstat is a violation of my privacy rights. I insist it

now I'm learning that other people feel free to clobber
me because I didn't lock the file before *they* started

\_ And if you're desperate 'find' with the right options might show
you a single file on the partition that's huge (and growing). Or
a 'du' if you're *Really* desperate or lazy.
\_ lsof can work wonders here. What can sometimes happen is that a
file can be deleted (or hidden because you mount something over
the directory where it exists), and you neglect to HUP a daemon
that's writing to it. The file won't actually go away until the
daemon closes it's filehandle. find will never find such a file.
lsof will. -dans
\_ What's wrong with du? du -hx -d1, then choose the largest

\_ Not all versions of du are the same. Just like not all
versions of find are the same, etc. My reply assumed a
base level version of each command that didn't have all the
zillions of options that the latest gnu has. I did say if
they have the right options, etc. Man pages are your friend.
My local base install is older and doesn't have a 'dont cross
file system boundary' option. I have the gnuer version also
but that was my choice to install it. The OP may not have.
Besides, du can be ugly and slow. It's an act of desperation

3/11 I need to start a daemon as a specified user at startup time, or
soon after, on FreeBSD. How can I do this?
\- you might be able to do it with su, but if it needs to bind to a
privilaged port and then relinquish priv, then it is more
involved, say if you want to run named as an unpriv user,
as we do. so the daemon is in fact in the details, e.g. if
you are also chrooting etc. --psb
\_ Actually, it's not so complicated-- ideally, it would simple
enough to do with a nologin/nopass user and an rc.d script. It
doesn't need any special privileges. su wouldn't really
work, because it requires a shell. If I try
sudo -u user daemon
then sudo complains that I'm already root and don't need to
sudo.
\_ Are you insistent on not having a shell for "user." I
don't see why su -u user -c "daemon" wouldn't work for
you (assuming you allow user a shell). Or try:
chsh -s "/bin/bash" user; su -u user -c "daemon";
chsh -s "/bin/false" user. And let me know if that works.
\_ Do you have the source for the daemon? If so, just patch main
so that it takes two additional args one for the uid/user and
the other for the gid/group to switch to after starting up.
If the daemon needs to bind to a port, it might be more complex, |

symlink telnet to ssh and let him believe that the users are using
telnet ;p
\_ The batch file will be placed in hundreds of Windows 98

\_ Why are you still even working there? I can't imagine
working in a place with a boss that stupid and an OS
that crappy.
\_ This isn't 1998.
\_ Include ssh along with the batch file. --dim
\_ He's a moron, true, but you've done your duty by telling him so, now
it is your job to make it work. I suggest a telnetd that auto-auths
anyone with no password. Yes, this is frightfully stupid, etc, etc,
but unless you want to polish your resume, swallow the bile and just
do it. Now is not a good time to get fired. Make sure you have it
documented that this is insecure and you told them so but were told
to do it anyway. You're then free from serious fallout. C.Y.A.
\_ I agree with the SSH suggestion. However, if you still need to
use telnet, you can embed a known password into the batch script.
You need to telnet to the same account, though. Or maybe have
the user save the password somewhere, but not ask on every
use.
\_ Create a server on a random port that does what he wants and have
your script telnet to that port.
\_ write a telnet program that automates the password and ship
it with your batch file. And document it that it's insecure.
\_ Upgrade windows. Realize that even windows has better tools
than telnet for running remote batch jobs.
\_ Whatever you do ignore the idiots here who give the 1990's dotcom
answer of "oh just quit!". Find a way to do the project and do it.

mapped correctly.
\_ AFAIK, DEL == ^?. BTW, why are you doing all this, termcap
terminfo, etc. should just take care of everything provided
$TERM is set.
\_ I guess it's not in my case. TERM is being set, but unless
I do a 'stty erase ^H', my backspace won't work (it'll
just output ^H). And if I log in from a linux box, it's ^? |

1/2 What are the pros and cons of using dnscache (djbdns) vs bind for
a caching name server?
\_ I ran djbdns as a caching/primary server for a few weeks. I
didn't like it at all. The thing was a pain to setup (dirs in
all sorts of strange places, a bunch of support pgms, ets) and
maintain (the files have strange syntax rules and there isn't
enough debug/error reporting).
In terms of its operation, I found that it didn't like using
certain nameservers (namely those of my isp) as forwarders,
cached the ips of dns round-robin hosts far longer than the
records were valid for, and played poorly with recursive
requests from mac's and win95/98.
I gave up and I'm using OpenBSD's BIND 4 as a caching ns now.
Its secure and it works for what I need.
\_ I had a similar experience with djb's publicfile (anon
ftp/http file server) It requires non-standard utilities that are
installed in non-standard directories (that's easily changeable
though) and it doesn't support certain ftp clients that people
use, such as netscape.
\_ if it doesn't work with my software, you shouldn't be
using it. -djb |

12/19 Why is EULER-PATH not as important as HAMPATH? (seriously, what is the
main diff between "edges only once" and "nodes only once")
\_ Euler path is a linear problem- O(V+E). Hamiltonian circuit is
NP-Complete, which means that it's at least as hard as
thousands of other problems. Produce a polynomial time
algorithm for Hamilton and you can crack nearly any public-key
cryptography system.
\_ isn't prime factorization NP-intermediate?
\_ So? All that means that you don't _have_ to solve Hampath
in polytime in order to solve factoring. If you _do_ solve
Hampath in polytime, this still gives you polytime factoring.
\_ what's the O(n) alg for EULER-PATH then?
\_ Find all nodes with odd degrees. If there's more than 2, halt
and return "impossible". Else, start at a node of odd degree
if there is one, and just keep going around while there're
edges from where you are which you haven't used yet. It's
fairly easy to prove that this will always find an Euler
path if one exists. -alexf
\_ Not true. Consider this graph: |_ _
/|_|
|
If you start at the top node, go down,
go right, then go diagonally down and
left you've cut yourself off from the
square at the right. But you can start
a new cycle that picks up that square,
then splice it into the other path. -ok
\_ I stand duely corrected. Apply the algorithm listed
above repeatedly to the graph, restarting at any point
which has unused edges coming out. You'll get a
collection of paths, of which all but at most 1 will
be cycles; you can then "merge" the cycles into the
path by just taking a "detour" around the cycle from
the point where the path touches said cycle. This should
still be linear. -alexf

\- hmm, using vt100 seems to work. tnx. --psb
\_ apparently there have been some "holy wars" about how xterm termcap
should work between debian linux and the rest of the world. but
it seems the new release of XFree86 has joined debian in this.
\_ XFree86 xterm has many extensions (like color) not present in
the http://X.org xterm used by the rest of the world. Some linux
distributions are rumored to have an 'xterm-sun' or
'xterm-r6' termcap entry for the older one, or you can always
compile the XFree86 xterm on Solaris.
\_ Yet another reason why *nix isn't ready for the desktop. Can't

something ancient like xterm is causing geeks problems how does
anyone seriously expect the rest of the system to be ready for

"Essential System Administration" (Oreilly) but then I started hearing
about this "purple bible", called "Unix system Administration Handbook),
ISBN 0130206016. Any recommendations?
\_ The "Essential System Administration" is a good beginning. It covers
lot of system administration topics, the kind of things that
sysadmins deal with on a daily basis. Keep in mind that this book
(like most technical books) is somewhat out of date. Also, the
bad in either. He does have a bad attitude, which is lame.
coverage of unix networking in this book is very poor (just the basic
concepts). You might want to also read the "TCP/IP Network
Administration" from the same publisher to cover the gaps in
networking.
\_ rule #1, sysadmins use 80 columns
\_ rule #2, the good sysadmins are usually fat and ugly
\_ you calling tom holub fat and ugly or a bad sysadmin?
\_ both.
\_ He's neither good looking nor a good sysadmin. But he's not

\_ Quick! Censor this!
\_ Did he ever graduate?
\_ why dont you ask him?
\_ I think he did...
\_ Just a bad attitude against those who are lame.
\_ Yes, Tom was there when they came up with the word
"cool". I always think of Tom when I think "cool".
\_ don't you have anything better to do? -tom
\_ Yes but it only takes about 30 seconds every
week and you're so asking for it.
\_ O'Reilly is more conceptual -- the bus book (which I believe
is the one you've mentioned -- it has a cartoon picture of
a bus on the cover) by Evi Nemeth is more application-oriented.
Those are the 2 most popular UNIX SA books out there. They
complement each other nicely.
\_ conceptual? not terribly.. but the O'reilly is indeed quite
good. helped me survive AIX administration.
\_ No offence, but while reading the AIX parts of that book (the
book often covers the specifics of Solaris, SunOS, Digital
UNIX, AIX, Linux, SCO, etc) I was often thinking "WTF were
they thinking when designing it [AIX]"
\_ The purple bible you're referring to is the "UNIX System
Administration Handbook" by Nemeth et al. It doesn't really have a
bus on the cover, it's more of a cartoon SUV. The purple one is
the 3rd edition. It used to be called the red book because the
2nd edition was red. It's a much better book than Essential System
Administration; it's more enjoyable to read, and, in general, it's
easier to get the information you need quickly with it. |

9/16 Anyone know who to get zsh to show all completions a la bash
(ie ls /bin/r[tab-tab] show all the files files in /bin/ that
start with r)? tia.
\_ Looks like it's a single tab on ver4.0.2, and tcsh-style ctrl-D on
ver3.0.8. Don't know when the behavior changed; presumably at
4.0. -alexf
\_ Try ctrl-D?

8/29 In the past few years I've been hearing a lot of bad things about the
quality of UCB EECS. I've heard that they're system level stupid
(Java-centric), editor incompetent (pico), and non-UNIX savvy
(M$ NT, MFC C++, etc). Is this true with the grad students?
\_ Latest I've heard is that 162 (OS) is taught in Java now.
\_ Holy shit!
\_ Ya, but recently, students have been programming GUI's in 61b.
That wasn't done too often 10 years ago.
\_ We had an intern this summer (EECS Junior) who had trouble
using the UNIX/Linux CLI (tar/gzip/make/cc). He used pico
almost exclusively, but he knew his C and Perl quite well.
I don't think that this is limited to Cal. We have some
guys from UIUC who can barely use vi/make/cc correctly
and struggle on systems without X11 but if you ask them
to debug code they can do it quite well.
\_ it's not the tool they use but how they use the tools.
If you want Unix + emacs + gcc , you are just as locked
from reality as the people you're attacking.
\_ I've been in the industry for 8 years and I still use Unix and
emacs everyday in all of the three jobs I've had. I'm also using
gcc in the third job right now.
\_ replace "want" with "insist". But then this has been an
often beated down topic not worth revisiting.
\_ i don't think it's the responsibility of a university to teach
you how to use the programming tools of the day. it's job is
to show you the big picture and understand the underlying
concepts. it's assumed that you are smart enough that you
could start using MFC correctly after 2 days even though
you've been using Qt for 3 years. Fundamentally, there is
nothing different between gcc+emacs+gdb/vc++, or gtk,qt/MFC,
or C++,scheme/Java. If you don't know how to make the
transition, you either missed the point of school, or you
should be attending a vocational school. -ali.
\_ Arrrrrrrrrrgh, matey! UCB EECS today warn't nothin' like the
swashbucklin' days of yore, when manly men like m'self walked
the decks of Cory Hall! Back then, we built our own calculatin'
machines out of gears we milled ourselves from rods of iron!
We 'programmed' 'em by movin' the gears into place with wooden
sticks, powerin' the whole works by leather belts attached to a
waterwheel! Men could lose their fingers in works like that --
you could tell the real 'hackers', because they were the ones
walking around with nothing but stumps for hands. Lily-livered
Windows-usin' nancy-boys that they let waltz out of the program
these days -- wait 'til they meet *me* 'round a dark corner
someday!
\_ you had milling machines? you had waterweels? jeez. I remmember
spending my first two years here running on a treadmill to
power the machines for the upper division classes, and cutting
gears out of mastadon tusks with bits of sharp rock.
\_ and you'll what, club them with your stump?
\_ you are right! Try taking CS 164 with VT220 terminals.
\_ Achoi could work on his 162 project with one VT220 terminal in
Cory.
\_ this is one of the funniest things I've seen on the motd in a
while. thanks for making my day.
\_ HAHA!!! What planet are you from?
\_ You didn't happen to write Myst and Riven did you? That would
explain all the inane puzzles....

\_ Don't some passwd commands require replication throughout the network?
E.g., I have a @cs.yermommasuniversity.edu address but there are 150
possible machines I can login to spanning different UNIXs and Windoze NT
OSs?
\_ I think this is rediculous too. A well designed NIS, NIS+, LDAP (or about
any other directory server) architecture should handle hundreds of clients
and thousands of user accounts no matter how often they change their
passwords. They must be rdisting passwd/shadow files or something other
equally dull on that system. |

8/22 Nowadays everyone tells me csh/tcsh sucks. I started my
undergraduate at Cal in 1990, and all of my first UNIX accounts
defaulted to csh. Given that csh wasn't the standard shell in UNIX
and it looks like all the other more advanced shells (bash, ksh, ...)
seem to have existed back then, why weren't new students set up to
learn one of those shells right at the beginning?
\_ *csh sucks for scripting, but for normal, daily, interactive
use tcsh is probably more intuitive. A well-config'ed bash
environment is every bit as good as tcsh (perhaps better w/
respect to using scripts) but takes a little more effort to
configure.
\_ last i checked bash's completions weren't as buff as tcsh's..
of course zsh is DA POWER SHELL
\_ bash's prompt doesn't do colors/hiliting.
\_ not a big deal
\_ all else being equal, it makes tcsh a better interactive
shell.
\_ All thing being equal, not being able to do the
equivalent of "command 2> errors " makes tcsh worse
interactive shell for me.
\_ what about >& in tcsh?
\_ in tcsh: (command > /dev/tty) >& errors
\_ yes, but that's a silly kludge.
\_ I just love how tcsh has different syntaxes for set and
setenv. brilliant.
\_ Because in 1990, csh could be found in nearly every form of *NIX
that had existed for the last five years. Think LCD. What good
is it to know tcsh when you're doing work on an SCO box at LBL?
It's why you learn "vi" or "ed." Because sometimes you're on a
POS without modern tools. Bearskins and stone knives, my friend. |

\_ you know, you can't expect the answer to every fucking dumb
question answered in a book. at some point, the book has to

\_ Well, you have to decrement the count in the SIGCHLD
handler and there is a small possibility that you might
miss a signal while you are in the handler. I need something
reliable.
\_ A reasonable objection, but if this is really an issue,
you can store a list of all children, and poll all of them

Word which "corrects" things that it thinks are

7/3 Isn't fgrep supposed to be faster then grep? On SunOS 5.7, I did some
timing by using grep and fgrep to look for a non-existing string in

6/15 In a controversial press release, RIAA announced that using FAT32 file
system should be made illegal. Recently it has come to RIAA officials'
attention that the FAT32 file system, commonly found in the PCs
running MS Windows software, can be used for storing pirated mp3 files.
"We were shocked when we have learned of such possibility. We are
already working closely with Microsoft to create a successor to FAT32 -
PHAT32, a new read-only file system." - said a RIAA spokesman today.
Microsoft's Steve Baldmer confirms: "We have been considering to
disable the write access for a while now. After all, our users don't
need write access to install applications any more. The upcoming
Windows XP release has everything that a user will need including
a virtual kitchen sink." SodanNews reporters were not able to reach
Sinkware Solutions officials, the makers of Virtual Kitchen Sink 2000
(tm), for a comment.
\_ Don't you mean Virtual Kitchen Sink XP? Surely they wouldn't ship

"What is NFS?" After a brief explanation from SodanNews reporters,
the RIAA spokesman was aghast. "Network file systems are an
abomination. Clearly they were designed to violate copyright law by
promoting the unauthorized distribution of music, and their use must
be stopped." Steve Baldmer responded, "This only proves that Unix is
evil. What do you expect from people who think software should be
free? They're pirates, plain and simple."
\_ And who says AI is useless!

What happens to the eof marker in b? If some program was reading b like

\_ it doesn't matter if it gets truncated by redirection or any other
means. redirection is a shell abstraction, not a file system
abstraction so the distinction is unimportant. tail -f just
regularly polls the time stamp of the file. if it's changed, it
rechecks the file.
\_ are you sure it's the time stamp it checks? because if there's
a process constantly writing to the file, only the last modified time
is changed; so tail can't reset it's pointer to the beginning of the
file by looking at the time stamp.

to flush its buffers will "win". files are not a coherent

4/30 Uninstall for Unix? Assuming you install something with the usual
./configure make make install routine, and later decide, "Fuck that
was the wrong distribution" or the wrong version or whatever. If you
aren't using a package, how do you know that you are removing all
the right stuff before you go to install the other version? I assume
that most big companies must depend on packages made on dev. machines
that are then installed, no? What is a reasonable policy as far as
this stuff goes?
\_ Install packages so that each of them is contained completely
within a separate directory, e.g. /opt/local/packages/pine-4.30,
then create symbolic links from /opt/local/{bin,man.sbin,lib,include}
to the real packages directory. If you need to remove a package
just nuke it's directory. Sure, there are still dangling symbolic
links, but at least you know what package they belong to if you
want to remove it. See how /opt/local/ is setup on OCF for example.
\_ Another neat idea would be to have a subdirectory within
/opt/local/packages/pine-4.30 called consolidated-links, or
something like that, which contains symbolic links to those
other symbolic links you were talking about. That way, when
you decide to trash a "package" you can run a little script
that will readlink and rm each link so that you won't have
dangling links.
\_ There's a package called opt_depot which manages a link
farm (in /usr/local/{bin,man,lib} by default) based on
installations in a package (or "depot") directory like
the above. http://www.arlut.utexas.edu/csd/opt_depot.
-tom
\_ Here's my little scheme, its similar to OCFs:
0. mkdir /usr/pubsw/ and required subdirs:
{bin,sbin,include,lib,libexec,share,etc,pgms,src}
(you only need to do this once)
1. untar your the source for your program into
/usr/pubsw/src/<program>/<program>-<version>
2. ./configure your program with prefix set to
/usr/pubsw/pgms/<program>/<program>-<version>
3. make && make install
4. cd into /usr/pubsw/pgms/<program> and ln -s
<program>-<version> to <program> (remove the
old link if you have one)
5. for new programs cd into /usr/pubsw and foreach
of the {bin,sbin,include,lib,libexec,share,etc} <dirs>
ln -s ../pgms/<program>/<program>/<dir>/* .
Now to acutally use the programs and libraries, all you
have to do is set PATH and LD_LIBRARY_PATH to point to
the /usr/pubsw/{bin,sbin} and /usr/pubsw/lib dirs.
To upgrade a pkg, you just download the new source, build
it, make install and change one symlink. To uninstall a
pkg just remove its directory. To downgrade, just change
one link.
The other advantages are that the top level directory is
clean (less overhead on directory reads) and source and
programs are stored using similar naming conventions making
it easy to track down problems and do upgrades, etc.
I'm giving you the brief version here. The full setup
also handles multiple architectures and OS revisions and
has some perl tools for cleaning up and installing. |

4/25 What's the syntax for searching the contents of each file with
find?
\_ why not use grep?
\_ find /my/dir -name myFile -exec grep -ne myExp {} /dev/null \;
\_ More elegant is find . -type f | xargs grep "search string"
\_ how about : grep "search string" `find . -type f` ?
\_ You want xargs in case find returns too many files for
grep to process at once.
\_ How is using xargs better than using -exec?
\_ MAX_ARGS! What if there are more files than MAX_ARGS?!?
Think before you do something dumb.
\_ God forbid... xargs performs a separate grep on each.
this may not be what you want. this can make it very
difficult to tell exactly which file the search matched.
Think before you give blanket answers.
\_ Uh, how does it make it more difficult? And where
did you get this notion that xargs spawns a call
to grep per file, do man xargs and look up default
values of -n and -s.
\_ grep -H
\_ that's great. How 'bout solaris?
\_ Easy: grep -r pattern .
If no gnu grep: find . -type f -print0 | xargs -0 grep -n pattern
If no find with print0 and xargs -0:
find . -type f -exec grep -n pattern {} \;

4/20 How come sed -e 's/[\ \t\n]/ /g' doesn't work for the tab and \n?
\_ obUsePerl
perl -pe 's/[\s\n]/ /g'
\_ perl -pe 's/\s/ /g' is sufficient --dbushong
\_ This is ugly, but it works for tab:
sed -e 's/'"`echo \"\t\"`"'/ /g'
Oh, and what's the point of matching SPACE, TAB, and NEWLINE
instead of just TAB and NEWLINE? Replacing SPACE with SPACE?
\_ you mean /bin/echo right? echo (shell command) wouldn't
work. Also maybe the guy means 's/[\s]+/ /g'
\_ yup, /bin/echo or /usr/bin/echo |

4/18 I want to filter a file with sed and store the output back into
the same file. Is there a way to do this without a temp file?
\_ no, if you want to do this use either awk or perl (perferably
perl)
\_ Please use a language (preferably English).
\_ perl -pi -e 's/.../.../g ; s/other/foo/g' file1 file2 ...
\_ yes. |

4/17 Sysadmin job posting --appel
/csua/pub/jobs/Skotos
\_ advanced experience with Windows and 2+ years Unix
experience for $15/hour? hahahaha
\_ advanced experience with Windows and 2+ years Unix
experience for $15/hour? hahahaha
\_ That's 2+ years Unix experience. Not Unix sysadmin exp.
I actually read the job, (unlike you), and that's ok for
a student slacker job as long as they understand the kid
has other things to do and is going to flake a lot. It
looks ok to me for someone who needs a first job and wants
more on their resume than "Member of CSUA/HKN/XCF/Fubar"
or whatever other student clubs there are. Non-job shit
may sound important to you, the student, but out here no
one gives a flying fuck what your non-job related beer
swilling student club was doing. -!appel
\_ the prequisite skills that are preferred is a bit over
the top for just 2 yrs xp. you're going to weed out
a lot of good people who would take such a low wage.
people already with all those skills can get much better.
\_ The preqs for a student job are always fluffed. They
obviously (to me) just want a kid who knows some
unix and is really good with windows. It looked
like a really straight forward job posting. Anyone
not afraid to apply is probably good enough to get
hired and I still say the pay is decent. This is
a student job. Your alternative as a student is to
get $6-$8 at the library or $8 washing bottles in
the Chem dept or $8 as an "engineering aid" for
eecs which has the same skillset requirements: a
student who knows some unix and a lot of windows.
There are *no* students who fit the exact criteria
of this job. They're fishing for what they can get.
This is no different than FTE job postings for much
higher end professionals. They ask for the moon but
will be happy with someone who knows the moon is
made of cheese. (You did know the moon is made of
cheese, right?) |

4/12 Why does "tee" or ">" not work on some unix systems?
\_ you don't have a filesystem
\_ there is a file system. this isn't a trick question.
\_ Wrong shell?
\_ I'm in csh
\_ How doesn't it work then? Maybe you don't have write
permission in the current directory?
\_ I can edit files and save files in it. Just not
pipe output to it. This is very confusing to me.
\_ But can you create new files in that directory?
\_ yes, and run make, and create executables, etc.
\_ I'm guessing that stderr is not getting caught and you're confused.
Try <something> 2>&1 | tee output (in bash)
or <something> |& tee output (in csh)
\_ I originally tried both:
execSomething |& tee output
execSomething | tee output
Both don't work. |

3/21 Under most OS's how do control whether a program core dumps or not
under a SIGSEGV?
\_ man signal
\_ you can also control it with things like limit. Note that certain
cases should never dump core (i.e. setuid() programs.)
\_ coreadm on Solaris lets you control that for people
who need to debug set*id programs. |
