Microsoft marketeese aside, caring for a network is a different set of skills than caring for unix servers (though there is a certain amount of overlap), and in any good sized organization the two are likely to be two seperate sets of people. That said, the best way is probably to set up a network with a few machines for yourself. Set up a few machines with a two or three nics each, and play with some simple routing setups. Set up a printer and file server, sharing the same set of files and printers out to multiple client platforms. Install and configure various packages like apache, perl, etc - from the source tarballs. Make your own network cables. Basically, play around, see how badly you can break stuff, and then learn how to fix it! -- Frank Sweetser fs at wpi.edu, fs at suave.net | $ x 15 Full-time WPI Network Tech, Part time Linux/Perl guy | If you can't hear me, it's because I'm in parentheses. -- Stephen Wright

WLUG Meeting TONIGHT Wed Nov 14th

by Andy Stewart

Hi Everybody, Unfortunately, I will be unable to attend this evening's WLUG meeting due to a rotten cold and a low grade fever which I seem to have picked up somewhere. I would encourage all of you to meet this evening, and some brave soul who has been in WLUG for a long time can get up and run the meeting in my absence. Have a beer for me at the Boynton! Here is what I had planned to report to the group this evening. I would like somebody to read this to the group in case folks haven't checked their e-mail before the meeting. 1) WLUG financials I have consolidated the accounts so that all of the WLUG money is in an account at the Lowell Five bank in Chelmsford, MA. I just paid the $50 fee to join the Boston User Groups as was voted at a previous WLUG meeting, and I wrote myself a $75 check for refreshments for the calendar year 2001. That leaves us with approx. $575.00 in the bank, which has been raised through your donations as well as install fest proceeds. 2) Annual Linux Showcase This event was not attended nearly as well as in past years, due in part to the fear of flying and by the fact that many computer people have been recently laid off. There were only half as many vendors as in the past, again due to the economy, I suspect. I found the quality of the techinical talks to be very good. I heard talk that there wouldn't be an ALS next year, but that Maddog was pushing for a small number of more local conferences, perhaps one in Boston. Some cool things which I saw at ALS: a) Linux running on a Compaq iPAQ, one running X and an xterm, the other running Qt Embedded with a bunch of PDA like applications. Refer to http://www.handhelds.org for more information. b) Latest versions of Gnome and KDE in action c) A large number of kernel hackers (including Linus) on one room d) A cluster of small embedded computers built by Los Alamos National Labs, all running Linux out of FLASH memory. e) A great beer selection at the Pacific Coast Brewing Company I personally spoke to Jim Gettys and a representative from the Free Software Foundation (I think his name was Brad, but I have his card). I might be able to get one or both of these folks to come to WLUG to give a talk in the future. I guess I'll have to save the freebies until next month. See ya later, and have a great meeting!

Re: [Wlug] installing Bugzilla

by Chad Pytel

I've installed Bugzilla before, and evaluated the install, and the package itself. I found the install document altogether straightforward and on a more up-to-date distribution than the one I used, (I needed to update several packages for MySQL and some perl modules, on RH6.2) the install should be fairly easy for someone with a medium amount of Linux experience. -Chad On Mon, 12 Nov 2001, Rick Gansler wrote: > I missed the last install-fest, and am anxiously awaiting the next one.

installing Bugzilla

by Rick Gansler

I missed the last install-fest, and am anxiously awaiting the next one. I'm considering deploying Bugzilla in my group, and was wondering if anyone has experience installing it, or even opinions about using it. The doc sends mixed messages about the complexity of the install: "Bugzilla is not a package where you can just plop it in a directory, twiddle a few things, and you're off." and then later on... "Installation of Bugzilla is pretty straightforward." The doc also makes it pretty clear that it'll run on Windows, but that there's additional complexity. It even sounds like it'll be easier to install on OSX than on Win2k, and that's fine with me. thanks in advance for any opinions, Rick Gansler

RE: [Wlug] DCHP Private IP Hostname Resolution

by Keller, Tim

Gary, I own the same router as you and I've got 2 linux boxes (one is pure, the other is duel boot). I just have static host files because the router has a sane DHCP server that assigns based on MAC address, so all your machines will keep the same address, regardless of OS.

I just installed a Netgear RP114 DSL router and I'm letting it set my private IPs with DCHP. My problem is that I need to resolve the hostnames between the 3 Linux machines on my private lan and the router isn't doing that. When they are booted in Windows the DCHP table shows the IP and hostname of each PC, but when booted in Linux the router doesn't resolve the hostname to IP...so when I ping a hostname I get nothing.

DCHP Private IP Hostname Resolution

by doug waud

Hi again I think we may be almost there! :-) > Unfortunately I can't modify any DCHP config > settings in the router To be honest, I had been having another "senior moment" and was picturing and old Linux box as the router! I really must learn how to read. :-) > so I have to find a way to > either get the Linux PCs to report their host names to the router or have > the router find the hostname from the PC. > > When booted in Windows they do that but in Linux they do not. It suddenly occurred to me that this must be the clue. So I went to the man page for dhcpcd (one dhcp client daemon) and found there is both a -H switch, which forces a hostname to that supplied by the server and a -h switch which sends the hostname to the server. I suspect the latter is what windows is already doing. (I mention the former as a reserve in case the -h does not turn out to work.) I also looked at my router (a Linux box) which happens to be using dhclient (another dhcp client daemon) and in its /etc/dhclient.conf there is a place where you can insert send host-name "box1.localdomain" which, it would appear, would do the same thing as above. (I should warn you that I am using SuSE so my /etc/dhclient.conf file may have a lot of stuff in it which is not usually there (SuSE is very good this way; they put it all in and then all you have to do is remove a comment and/or change some text. But the basic behavior of dhclient should be the same.) I'll stop here since I don't know what dhcp client you are using, but I think we are actually knocking on the door! > Of course I can always go back to a static IP and I might just ultimately do > that, but I'd like to know if there is a way to make this work.

Re: [Wlug] DCHP Private IP Hostname Resolution

by Gary J. Hanley

Hi Doug, And thanks for your input. Unfortunately I can't modify any DCHP config settings in the router (that I know of anyway), so I have to find a way to either get the Linux PCs to report their host names to the router or have the router find the hostname from the PC. When booted in Windows they do that but in Linux they do not. Of course I can always go back to a static IP and I might just ultimately do that, but I'd like to know if there is a way to make this work.

irda help

by Wesley T Allen

Hi gang, I've finally gotten the irDa stack working in my dell laptop (why, oh why is it disabled by default in the BIOS?). Here's my problem; I'm having trouble having the ppp connection being authenticated when a connection is made. My iPaq connects, has the host name of my laptop ok; but stalls there. I've followed the steps on the ir-howto, and it's what got me to this point, but there's no troubleshooting help for this particular problem. Here's the command I run to start the attachement... irattach /dev/ttyS2 -s 1 At this point my iPaq tries to authenticate, and then stalls. I would REALLY like to be able to transfer data between my iPaq and my laptop; and since I haven't heard of anyone being able to connect an iPaq to Linux via a USB cable, this looks like my best shot (besides, I really want to learn ir so I can control my TV from my laptop). Anyone got some ideas, if you help me solve it I'll try and submit something to the HOWTO so others can work around it. Wes

Re: [Wlug] DCHP Private IP Hostname Resolution

by doug waud

Hi again (with a red face!) > Sure, but the IPs are dynamic so the hosts file is out, right? Missed that (another "senior moment")! :-( Now I remember one reason I have been using static IP addresses :-) One way to cheat a bit would be to assign addresses but tie them to the MAC address of the ethernet card of each box, i.e. add something like host box1 { hardware ethernet 00:A0:CC:E4:86:CD; fixed-address 192.168.1.222; } to /etc/dhcpd.conf Then you could use the /etc/hosts route. Not an elegant solution but, what the hell, this is a rear-guard action :-) Unfortunately I have no dhcpd server running so I cannot test the following, but include it as a potential more elegant solution [and also as an attempt at face-saving :-) ] I believe there should be a file /etc/dhcpd.leases with sections like lease 192.168.1.25 { starts 2 2001/07/31 15:23:47; ends 3 2001/08/01 03:23:47; hardware ethernet 00:a0:cc:e7:6a:b9; uid 00:A0:CC:E4:86:CD; client-hostname "box3"; } If so with some cat|awk|grep|sed piping you should be able automatically to extract the dotted quad which goes with each host and give the former to ping to chew on. As I say, I can't test this. However, if you are masochistic enough to want to continue this thread, feel free to send me a sample copy of that /etc/dhcpd.leases file and I'll see if I can get a short shell script you could try instead of ping. On the more positive side, at least you now know the dangers of posting a query :-) doug -- Douglas R Waud, Professor Emeritus -- Pharmacology University of Massachusetts Medical School Mailing address: 17 Lantern Lane, Shrewsbury, MA 01545-2006

Re: [Wlug] Raw IO Howto

Can you do a bash$raw -qa as root and post the output. I assume that you used the "raw" command to bind the block device for raw I/O such as bash$raw /dev/raw/raw1 /dev/hdc1 On another note you may also want to check the permissions on the device file(s). This would cause the open to fail!

I get "No such file or device", which I also get if I do "ls /dev/raw/raw1" I have in /dev/{raw1,raw2...} If I change the code to open /dev/raw1, the open succeeds but the reads and writes then fail. Should I be able to see this mythical device in the /proc filesystem somewhere, cause I can't seem to find it...

Just a quick suggestion; open() sets perror(). try calling perror after your open() call, it might give you (and us) some insite to why you can't open the device.

Raw IO Howto

by Skip Gaede

Folks, I'd like to be able to queue read/write request to my Zip drive and bypass the buffering that goes on in the kernel. From what I've read, you can do this by binding the raw device (/dev/raw) to /dev/hdc1 for example. When I do that, I get a message that /dev/raw/raw1 has ben bound to char major 22 1. When I try open("/dev/raw/raw1",O_RDWR|O_CREAT,S_IREAD|S_IWRITE); it fails. Can someone tell me how to do this please? Thanks, Skip
