custom network intefaces during boot for Debian
Hello Here is a script modification for /etc/init.d/networking in Debian so that your list of network interfaces can be reconfigured during boot. Why would you like to have a script like this? Well, in my case, I have a laptop with a lan based eth0 and a wifi based eth1. If I am not connected to a lan during boot, I have to wait for the network interface on eth0 to time out with its dhcp request. With this script, it displays the current network config and gives me a chance to modify it. Here is an example of the script running: bic:~# /etc/init.d/networking restart Current interfaces: auto lo eth1 Customize networking y Enter interfaces besides lo. eth0 lo eth0 New interfaces are: auto lo eth0 * /etc/network/options is deprecated. Setting up IP spoofing protection...done (rp_filter).

problem with cvsweb
Hello I need help configuring cvsweb. I installed cvs and cvsweb to my webserver. I created a small repository and I can add and remove files. However, when I use cvsweb to read the repository, it can not output the change logs for the individual files. i.e, http://www.skink.net/cgi-bin/cvsweb is my url. If you click on the files in repository, you get a error message about not being able to parse the RCS output. What is the deal? John Davis
ssh keys keep changing.
Hello I keep getting HOST IDENTIFICATION HAS CHANGED! errors. How do I prevent these errors and how do I ensure that my machines are not under attack from someone?

fetchmail, sendmail, and mutt and sending mail with the correct a ddress
Hello I thought I had my mail system setup correctly, but then I noticed a problem. When I send mail from my linux box (which is connected to the internet via ppp,) it sends mail as if its coming from suit.ntrnet.net which is wrong. Suit is my hosthame and ntrnet.net is my isp domain. Ntrnet doesn't know about my hostname and thus can't forward mail to me. How can I configure my mailsystem so it sends mail as if its from ntrnet.net? ie., [EMAIL PROTECTED] instead of [EMAIL PROTECTED] Do I need to mess with the sendmail configuration, fetchmail, or mutt?

Looking for GCC developer and compiler backend people
Hello I work for a company that wants to hire a couple of gcc developers. This jobs requires some heavy thinking. You will be writing/modifying C/C++ compilters and must be comfortable with the GNU tools. If you got what it takes, please drop me a line. I'll forward your resume to the appropiate folks. Thanks. ps. I'm an engineer just like you and not a headhunter.
small fonts in Netscape packaged with Slink
Hello Why is that even though I have both the 75dpi and 100dpi fonts installed for X windows, Netscape still uses tiny unreadable fonts?
vim 5.3, gzip files, and Debian Slink
Hello I recently discovered that vim allows editing of gzip'd files. However, in my case, this capability is only available on my stock debian installation where I installed the vim package and not on my custom debian installation where I installed/Make'd vim myself. I tried to rebuild/config/make vim with gzip options, but I couldn't find any such option. (I searched for gzip, and gz in the man page of vim, the vim Makefile, vim feature.h, and vim configure but never found it.) I did notice that vim --version on the two machines were slightly different. The most obvious of which was that the stock debian version included a -DDEBIAN switch. I also looked for that define in the vim source config files, but I didn't find it either. Does Debian somehow do something to the gzip files before vim edits them or something? Is magic involved? Many Thanks.
make-kpkg doesn't make different kernel source revs.
Hello Why is that when I build a new kernel via make-kpkg, it doesn't make a new kernel rev. Scenario: Previously, I built a new kernel using: make-kpkg --rev Custom.1.0 kernel_image This command built my kernel and put an file in my /usr/src directory called. kernel-image-2.0.36_1.00_i386.deb. Then I built a newer kernel using: make-kpkg --rev Custom.2.0 kernel_image This command did change the date on the existing kernel package but did not call it kernel-image-2.0.36_2.00_i386.deb nor did it put the word custom in file name either. Is this the way this thing is supposed to work? Other simple questions: 1. When I used to do regular kernel builds, I used to do a make dep; make clean; make zImage, make modules; make modules_install. If I build kernels the debian way (aka make-kpkg), do I still need to do this? How about cleaning or rebuilding the dependicy list? ie. do I need to a make clean; make dep before I do the make-kpkg? 2. Does apt-get dist-upgrade get new kernel patches? Is there a way to get new kernel patches?
pcmcia and the debian way.
Hello This is somewhat related to my previous question concerning make-dpkg. Please correct me if I am wrong, but these are the steps I used to get my laptop working with a 3COM pcmcia ethernet card. I am still somewhat confused by this process and I would like to get confirmations on the process. In fact, I'd like to help document it for an official debian document if possible. All of this was done using kernel 2.0.36. 1. Installed pcmcia source from cd 2. 2. In /usr/src/modules/, i did a make-kpkg modules image. 3. In /usr/src/modules/pcmcia-cs, I did a debian/rules binary. 4. In /usr/src/linux, I did a make menuconfig Notable switches of interest were, Loadable Module Support - Enable Loadable Module Support - YES Loadable Module Support - Kernel Daemon Support - YES Network Device Support - Dummy NetDriver Support - YES (MODULE) Network Device Support - Ethernet 10/100 Support - YES 5. In /usr/src/linux, I did a make-kpkg -rev PcmciaTry.1 kernel_image. (Which did make a new kernel deb package, but it didn't include the name PcmciaTry in the file name.) Brian Servis on this list told me that the Pcmcia string probably didn't show up in the name because it didn't recognize the -rev switch. I only used the -rev switch, becuase the -r switch was unrecognized and that's what the how/faq said to use. 6. In /usr/src/, I did a dpkg --install _kernel_image_name. 7. Reboot. 8. In the /usr/src/modules/, I did a dpkg --install _pcmcia_module_image_name 9. In the /usr/src, I did a dpkg --install _pcmcia_modules_images_name. Note, I can't remember the names exactly for the two different files in step 8 and 9, but they were different. Results, this did get my pcmcia ether card working. Looking back on the steps and reading Brian's helpfull, text, I should have added a make-kpkg clean between steps 4 and 5. Is there anything else that's obvious? Lastly, if I get the latest pcmcia source using apt-get, do I need to get a newer kernel source?

intall hang: 'unknown pci device'
Greetings! I know this is a classic problem but I don't know how (or if) it can be circumvented. I've bought a nice new laptop and have partitioned it with win95 and OS/2 and thought I'd make a trio and put Linux on it. (Note: I'm not a _complete_ newbie to Linux - I've recompiled the kernel and futzed about but I'm not a veteran either; my domicile is in OS/2 land.) When I use my trusty bootdisk (which I made months ago for my desktop machine), it _hangs_ on the error: WARNING: UNKNOWN PCI DEVICE (1039:5107). PLEASE READ INCLUDE/LINUX/PCI.H The system, purchased from AT-Computers (http://www.montananet.com), is: Sager Computers Laptop (NP6287A) P166MMX PnP System Soft SiS-510X (6x00-05-13) BIOS Ver: 1.01.26 05-13 Date: 06/16/97 Is there hope for a workaround? If I can't run Linux I have to consider returning the system. Probably won't return it but is that the prospect I'm facing? Can I find something in pci.h - I haven't had a chance to look on my desktop machine - which I could remove and still boot? (Oh, and I sent a message to [EMAIL PROTECTED]) I'd _really_ appreciate some help.
