2/26 router question: sharing static ip address, but pc's in lan have own machine names and web servers. how does router know which machine a url refers to if the url just has the ip address in it? \_ What's running NAT? Is it a linux/windoze box or one of those NAT hubs/switches/routers? \_ pc 's and linksys router. \_ Is the idea you want your web server accessible from outside your LAN? \_ yes but there are 2 computers w/ web servers, both need to be accessible. The hope is that the router would disintiguish by MAC address but the 2 machines would have the same ip. \_ Let's say I request the web page <DEAD>www.yermammy.com/foo/bar.html<DEAD> Your browser will put the following in the HTTP request header: Host: <DEAD>www.yermammy.com<DEAD> Now, I'm not sure if linksys routers do this, but the way it would work is that the router would see the packet is going to port 80, look for and interpret the host field, look at a mapping of host field settings to local IP addresses (which presumably you have set), and finally direct the packet to the IP address of the appropriate web server. \_ how could the router tell which IP packet is destined for which machine? Incoming IP packets aren't going to contain MAC addresses. You'll need to have the web servers use different ports. \_ Yeah, this is the most straightforward way. <DEAD>www.yeremammy.com<DEAD> (port 80) <DEAD>www.yerbrother.com:81<DEAD> and then port forward. \_ unfortunately, the 2 "web servers" are actually DAQ board cards that require an IP addresss but use the same port (no way to change port) even if they have unique IP addresses, the outside would still point to 1 ip address/hostname and same port for both of them. \_ web server 1: 192.168.0.1:80 web server 2: 192.168.0.2:80 port maps: ; router:80 -> 192.168.0.1:80 router:81 -> 192.168.0.2:80 \_ You've gotta stop posting useful info to the motd. People will come to expect something better than the typical trolling and then what? |

2/26 Is tax software like TurboTax good for people who trade stocks and just purchased a home last year carring a mortgage? I mean is it good enough to guide you through all the misc stuff like county tax, escrow, point fees, etc. and squeeze in every cent of possible legal deduction one can claim? I'm thinking about whether I should use TurboTax or get a tax accountant. Thanks. \_ get a tax accountant, doubt TT is that optimal. (otherwise, there will be no tax accountant) \_Falacious argument \_ Accountants become more valuable the "weirder" or more complex your situation is. This guy's situation sounds fairly normal. Then again, he sounds like an idiot, so... \_ Therefore, as an idiot, he should get a tax guy to do his taxes. |

2/26 I assume GDB will allow me to do a trace on any core dump. correct? Is there a better way? (pedants: if so what?) \_ I use gdb all the time to analyze core dumps. The problem is that gdb gives this facad of a horribly complicated debugger which scares people away. You just need to start off with the basics. Compile and link everything with the -g option. That's all you need. you can invoke gdb from the shell or emacs by calling gdb a.out core (substitute a.out with your program). bt is you best friend for finding where a program crashes. You're on your own from there. It's sad, I'm not even a software engineer and I use debuggers more often than most of them do. \_ I use Java. I don't need to debug. My programs are guaranteed bug-free by Sun. \_ i can't think of anything better than what gdb+emacs does. what feature do you need? -ali |

2/26 I've converted my small network (10 workstations) to NIS+. It's a pain in the ass to manage. Is solstice any good at managing them? do I have any other choice? Thanks. \_ DNS \_ wtf does DNS have to do with NIS+? Most sites that use NIS+ troll Stop deleting my troll anotations. \_ Use better annotations: t = troll, w = winston, etc \_ Use better annotations: h = hamster, w = winston, xxx = rebecca lord etc use it mainly for things other than host name db. \_ LDAP \_ hessiod \_ ew. \_ get a nocmonkey or a labrat \_ There is no secure alternative to NIS+, save MAYBE hesiod/moira. Come on, it shouldn't be THAT bad to manage. what's giving you the headaches? \_ what about netinfo? |

2/26 Hey folks, I'm looking for something like Purify but cheap. What do people do for C programming to guard against memory bashing and leaks, other than write their own malloc and buy expensive software from Rational? \_ wasn't there some kind of program to analyze C code for no no's. I think it was called something like lint. \_ uh, lint is a syntax checker. it does not figure out if your code has memory leaks. \_ memory bashing. memory leaks. \- wasnt there something called electric fence or something like that? --psb \_ Yes. -lefence on some Linux systems, or you can go and get the library. However, efence just puts illegal pages before and after every memory allocation. This means that if you write outside of the bounds of any allocation, it seg faults immediately there, showing you the memory error immediately if you're using a debugger. This is VERY demanding of memory however, and slow. Memory use will 10x, speed will .04x. efence is in NO way as good as purify.... --PeterM |

2/26 I want to buy a cable modem instead of renting AtHome's. Recommendations? \_ It's $5 a month. You'll never make the money back. I recommended you rent. They'll change the standard long before you make up the lost rent. And then when you lose net and call them they'll say, "Sir, according to our records you're not using an @home rented network device. We suggest you buy a new one or we can rent you one for only $5/month plus a $75 install charge." As a modem renter with a broken modem, they send out a truck in a few days at no extra cost and refund you the lost net time. |
