6/26    This command is hanging on my RH linux box:
        ping -c 1 -t 1 http://www.yahoo.com
        It doesn't hang from here on timeout.   What should i do?
        \_ you are setting your TTL to 1 hop? why would you do that?
           you are basically saying "if you have to go through more than
           1 router, die.." and im sure yahoo is at least 5 hops away.
           -t is in hops, not seconds.. read the man page.
           \_ Wrong answer.  -t is timeout.  -T is ttl.  He almost certainly
              has a problem with his resolver.  Check /etc/resolv.conf and
              make sure your nameservers are working properly. --scotsman
           \_ The man page says " -t ttl Set the IP Time to Live."
              That's *IT*, though I don't really care.  I'd be happy to be
              saying what you are saying above.  It still shouldn't
              HANG.  It doesn't if you do it from here and it doesn't if I
              do it from my other linux box (diff network).  The question
              is:  WHY IS IT HANGING? (this is related to a bunch of hanging
              pings i get from my network test that run without the -t flag)
              Normal pings work the vast majority of the time.   (haven't
              got one to fail for me manually, just 8/1440 in the cronjob)

9/18    I just installed Red Hat Enterprise Linux 2.1 and everything
        seems to work ok except my httpd cannot be reached outside
        of the box. I have no problem pinging and sshing into the
        system, but http connection would not work. However, it does
        seem to work when I launch firefox within (same machine).
        What could cause this? I'm not familiar with PAM and I'm

2/5     I thinking of installing Debian Linux because a friend of mine says
        it's much easier to deal with when you install programs. For example,
        during an insntallation the installer will check for ALL dependencies
        and automatically download the right .so files you need. The claim
        is that RPMs are not as thorough and that there's more work involved.
        Has anyone tried both RH and Debian and have comments on this? ok thx

1/5     So who else thinks that Linux Kernel Development has gone haywire?
        WTF is up with this movement from an 8k to a 4k stack in the kernel
        that breaks tons of existing drivers that are ported over from
        Windows? And wtf is this crap doing on production distros like
        Fedora? Don't they realize that if you're going to have a large
        install base that you can't arbitrarily do crap like that anymore?

12/9    Has anyone had experience with using a file under NFS as basically
        a region of memory shared between separate machines? I.e., the
        machines lock the file and read/write it to communicate. Speed is
        not a huge concern, but can this be done reliably? Are there
        caching issues? Will fsync work properly over NFS? This doesn't
        seem ideal, but thanks for any advice.

11/3    Is it just me or does Adobe Acrobat tend to go apeshit in Mozilla on
        Linux?  I've also noticed than on WinXP it stays running even after I
        close the page that was using it
        \_ Are you using Acrobat 6.0 Reader? If you are, downgrade to 5.0.
           6.0 has a lot of problems, period.
           \_ Acrobat 6 doesn't exist for Linux.

10/28   I just built a terrabyte raid server using linux. The distro is
        an older version of RH 8 (need it to keep compatibility with certain
        apps). I formatted the raid to be XFS. The server is an NFS server,
        and I appear to be hitting the 2 gig file limit. According to the
        docs I'm supposed to be able to get beyond the 2 gig limit with
        RH8. I have compiled a new 2.4.27 kernel to replace the stock

10/8    Anyone recommendations on a decent 64-bit linux distro?
        \_ There aren't very many, and the ones there are seem immature.
           Yer hozed.
        \_ SuSE 9 isn't half bad. Several of our customers are
           using it and seem to like it. RH EL 3.0 is okay as
           well.

7/14    I bought several Intel GigE nics and one of them has a
        bad mac addr (all ff's). dmesg shows the card as detected,
        and proc/pci lists it, but ifconfig doesn't show an eth*
        entry for it. Does anyone know how I can set the mac addr
        so that I can use the card? (I'm using RH 9, but I can
        just as easily stick the card in a WinXP, FreeBSD or

5/27    In what ways are FreeBSD superior to a good Linux distro?
        \_ Why do you hate Windows?
           \_ Why do you hate Linus?
        \_ *BSD has a better IP stack.
           \_ In what way?
           \_ Aren't they the same now?

3/12    RedHat, Suse, or Debian? I am seriously thinking of installing
        one on my machine...
        \_ Free RedHat as you know is has reached it's end. RedHat 9 was the
           last of it. There will still be RedHat Professional, which is
           RHEL but only costs $90. I highly recommend Fedora if you want
           to keep up with the latest and greatest in Linux.

3/1     Does anyone know how to tell if an opteron system is running a 32
        bit linux kernel or a 64 bit linux kernel in RH 3.0 EL? tia.
        \_ Guessing: check the bootup logs?  uname?
           \_ it seems to print out x86_64 regardless of the kernel.
