Kernel Upgrade results in Network Domination?


I swear, all I did was install and compile a 2.6.7 kernel (upgrading from 2.6.5). It's been a while (1.5 months) since I compiled a kernel, so I wasn't up on all the options, plus I added a few extra since I'm going to be upgrading this system soon (within a month, hopefully), but am not quite sure what mobo I'm going to get, so I wanted to cover a few extra bases.

The thing is, I connect via a LAN; the Ethernet DSL modem is connected to my boyfriend's machine, running Win2K. We use a software router (WinRoute), but he decided to give Kerio Personal Firewall a go a couple of days ago. It was working fine... but then again, I hadn't rebooted... until I upgraded my kernel.

As soon as I rebooted, we both lost our Internet connection (!!!). Well, of course I lost mine, if his went out, but why the heck did his go out? Normally I am unable to affect his connection, as he does not connect through the router-- I do. If he then reboots, he can connect (and thus so can I).

I can only think (as weird as it sounds) that I have set some kernel option that is taking over the routing or the network in some way (although I have no idea in what way this could happen, since I changed nothing except the kernel, and uncommented some additonal ALSA modules in /etc/modules.d.autoload/kernel-2.6, as I had compiled ALSA differently this time). I had set "Network Packet Filtering", but I turned this off again and it did not change a thing.

Or else it's the stupid firewall, but I don't know a thing about that.

If it's really me, I could certainly trawl the .config for both 2.6.5 and 2.6.7 and try to find what setting had changed, but it would be really a big help if somebody might give me even a ballpark-sized area to start looking in (as that would be a significant reduction in the trawling, given that I don't have a clue what has happened here).

In the event that it would be useful, here's the contents of lsmod and dmesg:

I don't see a doggone thing that might even relate to this, except that the eth0 link goes down at the very end (presumably because the Internet connection has gone down long before, or because the firewall is locking me out).

But even if the issue was the firewall, I still don't see how that would knock out his Internet as well, so I'm stumped. The system works fine otherwise (once I fixed my few false starts with the ATI drivers, ALSA, and bootsplash), so it's not that the new kernel doesn't work, or that I have some horrible misconfiguration of my system. Heck, the network even works fine, once he restarts.

Any guiding light appreciated (if someone could even definitively confirm that it's not from my end, but from the Windows end, that would be more clue than what I've got now).

TIA,
Holly

You don't say how the W2K machine is connected to the DSL modem but like you I don't see that it should be your machine that caused the problem unless there's something changed in your network set up that's upset the routing software. I'm not familiar with WinRoute - I've used proxy software in the past (AnalogX and Proxy+) on a W2K box to share internet connection without experiencing anything similar. I have experienced problems with personal firewalls on WinXX machines so it could be connected with that. Unfortunately there've been a few changes happening simultaneously so unless you can duplicate the problem it's going to be hard to find.

I'd suggest running ethereal (or similar) on the W2K machine as well as your own to see what's going on.

Good luck.

Yeah, I did (or at least I thought I did):

the Ethernet DSL modem is connected to my boyfriend's machine
But the problem is solved; as we suspected, it was some (presumably mis-)configuration of the Kerio Personal Firewall. He didn't like it for his own reasons and removed it; lo and behold; upon a reboot from me, nothing happened (the network and Internet connection stayed up).

Networking is my weak point, and he was also running KPF "incorrectly" (alongside WinRoute as opposed to instead of WinRoute), but even I can see that if he wants to reinstall the thing, it's a Windows problem now .

Thanks for your support during my brief panic attack.

Glad you're sorted - lack of precision on my question - what I mean't about the DSL connection was whether it's USB or ethernet.

I know a lot more about networking and Windows than I do about linux - only really been using linux seriously for a few months since I decided to retire my ancient Netware 4.11 server (Pentium 12OMHz 64Mb RAM) and managed to replace it with linux server using Samba as a PDC.

I'd ideally like to replace my Windows desktops with linux but despite the fact that the lowest spec is an Athlon 550MHz with 256Mb RAM running SuSE 9.x with KDE 3.x is slower than Windows! From what I've read this seems pretty common amongst the main distros. I'm going to try Gentoo to see what difference that makes and knowing you're a fan are there any good sources of info for first timers or do I just read the handbook and set aside a couple of weeks?!

You'd really do best to read the Handbook, as it's an excellent piece of documentation for the install.

The docs on the User Docs page of the Gentoo site should pretty much cover anything you might need in terms of system administration after the install.

You probably won't need a couple of weeks; depending on what you install and how you install it (you can install a number of large apps from packages, you know, it's just not really recommended, as you lose all of the optimizations you've set for compiling). It took me a couple of days, but that was mostly because I was compiling large apps, and also because I was not focusing on the install constantly for 2 days (it was a busy weekend ).

And of course, the system is installed relatively quickly (a couple of hours, given that you're following the Handbook very carefully during that time), and if you just install a light WM to start out with (IceWM, fluxbox, XFce, WindowMaker, etc), you can then begin to use the PC while compiling KDE/GNOME/Mozilla (which each take several-- and, by "several" I do not mean "two or three", more like "four or six or more"; OK, Mozilla takes two or three-- hours to compile on my Athlon 2200+ at 1.8GHz). There's plenty of stuff that compiles fast to give you a working environment while you get your more permanent setup set up (if you really must have KDE and/or GNOME, rather than just some of their apps).

But you may want to consider streamlining SuSE a bit before making a drastic change; let's face it, a commercial distro (which likely has many non-essential services turned on) using the most "feature-filled" (or bloated, depending on your viewpoint) desktop environment is not going to be the Ferrari of the desktop.

Try turning some things off (or uninstalling them)-- do you use sendmail? Postfix? Get rid of them (I don't even install them anymore). Try XFce4 or IceWM for your desktop. Try Firefox or even Lynx (or Links) instead of Konqueror, and The Claw 2 for file management (not integrated, but maybe you don't want that). Try Mutt instead of KMail, and irssi instead of KVirc. Yes, they're console-based apps, but that's not necessarily a bad thing.

There are tons of applications for every purpose that are not integrated with KDE; if you can eliminate the use of KDE, you've already speeded up your system by a huge amount, as managing all that integration with itself makes KDE a pretty slow desktop on even the fastest hardware.

Trim your system down a bit, and explore different ways of working with your PC in the first place, and (if you like SuSE), you may find you don't need to change distros at all.

Thanks for that - I'll have a go at trimming SuSE down first - that's a good idea anyway and I've tried and liked Firefox on windows machines so that's good too - the only issue I have is getting alternatives to IE working successfully with all my internet access (banking sites in particular). Yes I'd come to the conclusion that KDE itself is grabbing more and more resource and as I'm starting to learn more I'm using non-KDE ways of doing things anyway so I'll definitely have a look at alternative window managers.

I hadn't followed through on the fact that once the system itself is up and running you can start to use it whilst compiling other apps - I'm used to reinstalling Windows which is definitely a single user process!

Had a play with a few wm - decided that there are a lot of pluses with KDE that I've already got used to so I'll leave KDE on the main machine for the moment.

Going to have a play with Gentoo on Tosh laptop (currently XP/SuSE 9.1). Not happy with SuSE 9.1 anyway so rebuilding from scratch. Need XP for work and only got recovery disks so it's reinstall XP, install basic SuSE 9.0 resizing Windows partitions and setting up multiple partitions for later use and then Gentoo! I'll keep notes of what goes wrong as I do it and how I fix it - expecting more than a few issues because it's a laptop - but because it'll have a working SuSE environment I'll hopefully be able to use that to short-circuit any major issues.

Sounds like a plan... and even one that's covered in the Handbook (installing Gentoo from within another Linux OS), so you should be good to go. Looking forward to hearing of your success (in another thread, naturally-- maybe even on the Gentoo forums ).

Just in case you wondered why I haven't appeared yet on the Gentoo forum!

Managed a Stage 1 with a few errors but successful enough to boot up, however, found myself just following the instructions without really understanding what it was all about. Therefore have gone back to basics to try and understand how everything hangs together first.
