[gentoo-user] Firewall recommendations
Hey again everyone, Still new when it comes to Gentoo and so I'm stuck when it comes to picking a firewall to use. I know that most (if not all) of them just use iptables to block/allow stuff but I like the simplicity of having it do it automatically. Anyway, I've been using APF on CentOS which worked great. Setting it up couldn't have been easier. Unfortunately it doesn't seem to want to play nicely with Gentoo. So now I'm looking for a new firewall. I tried Shorewall but it seems a little too complicated to set up. Is there something as simple as APF that works with Gentoo? Thanks in advance for anyones recommendations. -- gentoo-user@gentoo.org mailing list

Thanks for your responses guys. I'm in the process of emerging firestarter right now.

Re: [gentoo-user] Recommendation on how to format my new drive

For now, I can only think to give 10GB to windows, all other space for gentoo. Please share your instights how many partinions do I have to do, what sizes. I would value all the input. Thanks a lot. Boris. Hi Boris, Really it's up to you. It all depends on what you plan on doing with each partition. If you plan on using Gentoo primarily, then you'd probably want to give a bigger partition for Gentoo. Or if you plan on using Windows more, then give more to Windows. Just make sure you have enough space for any apps you might want to install for each OS in the future. Nothing worse than being 100mb short of space on an install :) -- Jon -- gentoo-user@gentoo.org mailing list

The OS is installed on a regular Pentium 4 (32bit), but will be installed on a Pentium D that can run 64bit, but will be sticking with 32bit. Is that what you wanted to know? -- gentoo-user@gentoo.org mailing list

I can tell you from my experience, since I use PentiumD cpu, that recompiling with -march=prescott gave me better performance then -marh=x86-32, especially in disk intensive and multimedia applications, such as video encoding and large database access. Hi Mark, Thanks for the tip! I'll be sure to switch my CFLAGS to that. I might as well make the system run as fast as it possibly can. What did you set your MAKEOPTS to? I was thinking -j3 because of the two cores plus one. Did you do the same? -- gentoo-user@gentoo.org mailing list
[gentoo-user] Install Gentoo on one machine, then move the drive to another
Hey again everyone, Here is my situation: I have CentOS running on a system in a datacenter, but want to switch to Gentoo. Basically what I've started to do is installed Gentoo on a P4 3.0Ghz machine at home, and plan on moving it to a Pentium D 2.66Ghz. Now if I configure/compile/install all my software on the P4, and the kernel is configured for all the hardware in the other machine, will it magically work, or will it freak out? My other concern is that maybe the applications won't be optimized for the other machine. If this is the case, once it's down there, could I simply emerge all of my programs one at a time? My reason for doing this is to minimize downtime. I didn't want to take the server offline for a week while I take my time configuring a new setup. This way it should only be down for maybe 5 minutes while I do a hard drive swap. Thanks in advance for anyones thoughts on this. -- gentoo-user@gentoo.org mailing list

Re: [gentoo-user] Grub problem. Gentoo doesn't boot. VFS Cannot start...
Hi Isern, I actually have the exact same problem, and someone was kind enough to help me so I'll pass on the same info. Basically my problem was that I hadn't enabled the proper IDE Chipset (or SCSI if you use S-ATA) in the kernel. When I booted off my Gentoo install cd, I can 'lspci -v' which showed me what type of chipset I was looking for to enable in the kernel. Give that a try and it should solve your problem.

[gentoo-user] sshd issues
Hey all, I've been using other distributions for a while (CentOS, Slackware, Red Hat, etc) and finally switching to Gentoo, however this oddness with SSH is getting to me. It seems when I SSH into my machine it uses keyboard interative mode, where as I'm used to every other distro using just password mode I think it is. I'm wondering if there is any way to change this. I tried comparing /etc/ssh/ssh_config between my CentOS machine and my Gentoo machine, and both files are pretty much the same, and everything is commented out anyway. Any light someone could shed on this would be much appreciated. Thanks in advance! -- gentoo-user@gentoo.org mailing list

[gentoo-user] New to Gentoo. Having trouble getting it started for the first time
Hey everyone, I'm new to Gentoo, but not to Linux. For some reason I seem to be struggling to get it booted after installing. Basically my setup is I have 3 partitions as follows: /dev/hda1 (32MB EXT3) used as /boot. /dev/hda2 (512MB) for swap, and the rest is on /dev/hda3 (ReiserFS). The contents of my /boot/grub/grub.conf is as follows: default 0 timeout 30 splashimage=(hd0,0)/boot/grub/splash.xpm.gz title=Gentoo Linux 2.6.17-r8 root (hd0,0) kernel /kernel-2.6.17-gentoo-r8 root=/dev/hda3 Everything look normal so far? Well when I reboot, and select Gentoo on the GRUB list, it starts to load and then I get the following error: VFS: Cannot open root device hda3 or unknown-block(0,0) Please append a correct root= boot option Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) Any help anyone could provide would be greatly appreciated!

VFS: Cannot open root device hda3 or unknown-block(0,0) This is not a problem with your grub configuration. The unknown-block(0,0) tells me that the kernel cannot find a device for hda3. You probably missed either the device driver needed for your IDE chipset, or IDE hard drive support in your kernel configuration. If you need help figuring out what you need here, post the outputs of: grep -v -e ^# -e ^$ /usr/src/linux/.config lspci -v HTH, -Richard Hi Richard, I think you are correct. I just scanned through the output of those two commands and I believe I may have missed the IDE chipset. I'm going to try enabling it and see if that helps. As for the other two responses, I did compile ReiserFS directly into the kernel, and also tried changing the kernel line in grub.conf to read kernel (hd0,0)/kernel-2.6.17-gentoo-r8 root=/dev/hda3 with little success. Hopefully this will work though. Thanks again! -- gentoo-user@gentoo.org mailing list
