FYI some braindead benchmarking, reiserfs vs ext4, kernel 2.6.35-gentoo-r8 Copy same DVD image from internal reiserfs drive to freshly formatted external drive; reiserfs1m37.530s ext43m15.074s Then image copy on that external drive; # time cp CentOS-5.3-x86_64-bin-DVD.iso CentOS-5.3-x86_64-bin-DVD.iso2 # time cp CentOS-5.3-x86_64-bin-DVD.iso CentOS-5.3-x86_64-bin-DVD.iso3 reiser1m44.719s and 1m51.441s ext43m24.337s and 4m30.534s Not that is matters, but create filesystem on 2TB drive; reiserfs1m17.373s ext46m3.421s Didnt see that coming, I guess i'll stick with reiser3

[gentoo-user] Where should i ask Gentoo/Xen/hardware questions?
Hello, first: where should I ask the following question? We successfully operate some HP Proliant DL380 G3, using Gentoo Xen-kernels as Dom0 and DomU. Now i tried to upgrade to Generation 4 and 6: * HP Proliant DL380 G4 * HP Proliant DL380 G6 Grub works fine. After selecting a kernel to boot, it is loaded and starts operating and fails some lines later with a kernel panic. The kernel seems not to find the HP SCSI controller (/dev/cciss/...). I made sure, that the kernel has build in the needed drivers as described here: http://en.gentoo-wiki.com/wiki/HP_ProLiant_DL380_G5 Funny is, that the Gentoo boot images do work, for example install-x86-minimal-20100216.iso. I use the iso images to boot the system initially, initialize the SCSI disks with fdsik and mkfs... and then mount the SCSI drives (/dev/cciss/...), copy a working tarball-image, populate the filsystem and then use the grub shell make it bootable. Attached is a screen shot with the error message. Best regards Olaf attachment: 20101006.kernel panic screenshot.png

Re: [gentoo-user] Where should i ask Gentoo/Xen/hardware questions?
If /proc/config.gz exists when you boot from that image you could compare that to the .config file that you're using to see what the differences are. I tried it. I spend much time on it. For me the only way is to use a GUI diff program like Meld, otherwise i find it too difficult to notice the differences. :) I also tried to use the config of the allround boot disks (in /proc/config.gz of the running livecd system).

So i tried to ship around this... Would you suggest to try this way? Should I try to fix the Xen-Kernel from Gentoo with some HP driver source code? Or could it be a completly other issue? I'd be very confident that the driver code will be identical in xen kernel to regular kernels of the same version. You could verify this by running md5sum against the modules source codes. If they are the same there's no need to worry about the driver code. Put your xen .config and the config from the boot disk that works up somewhere public - maybe we can spot the problem?

[gentoo-user] Zynaddsubfx with keyboard input
Hi, I am currently experimenting with ZynAddSubFX. This synth has a virtual keyboard, which is accessible via clicks of the mouse and via the keyboard of my computer. When tuning parameters of the synth it is often of help to hear, what the current parameter does with the sound. All parameters of ZynAddSubFX are altered via the computer mouse. Doing so will change the window focus of the virtual keyboard to the parameter window and hitting the keyboad of the computer then will have no effect (the keypress is directed to the window with the parameter knobs, which has the focus now). Zynaddsubfx will accept input from midi devices also. I am no midi expert at all. :) Is there any Virtual keyboard or anything else, which can be used to interpret keyboard (computer) events to midi somthing and send them to ZynAddSubFX? Thank you very much in advance for any help! Best regards, mcc
Re: [gentoo-user] Finalizing my backup system
I'm using backupninja to backup data from my laptop, desktop, and remote server onto a remote desktop system. backupninja is very simple and is really just an interface to a few other programs including rdiff-backup. I'm not worried about a good restore method for now, I want to focus on keeping it simple and protecting my data. This is the first time I've set up a real backup system and I'd love to get some advice from you guys. I've got a few questions. 1. This is the first time I've used passwordless SSH keys. root on each system being backed up logs into the remote desktop as a normal user to store the backups. Is this pretty safe? I suppose if root is compromised on any of the three systems being backed up (via physical access or otherwise), the remote desktop will also be compromised as a normal user. Maybe that normal user should be extraordinarily unprivileged? You can limit SSH access to only certain commands. On the remote desktop machine, you probably had to add an entry to the SSH authorized_keys file. You can prefix that line with the command that the user is allowed to run. For example (I use rdiff-backup too): command=/usr/bin/rdiff-backup --server,no-pty,no-port-forwarding ssh-rsa big_ugly_key I tried both that and simplified versions of it but it seems to prevent the login from working. It hangs on the following command, which works if I don't add the above: ssh -o PasswordAuthentication=no 1.2.3.4 -l user 'echo -n 1' Should it be working? I noticed I have ssh-dss instead of your ssh-rsa. - Grant
[gentoo-user] IP aliasing problem
I'm trying to use a different SSL cert in apache2 for each of the two domains on my server. I don't want to use SNI or subjectAltName because of lacking browser support and I want to use port 443 for both domains. I think this means I need to use separate IP addresses for each of my domains. I have 5 usable IPs from my host and I've defined 2 of them in /etc/conf.d/net like this: config_eth0=( 1.2.3.1 netmask 255.255.255.0 1.2.3.2 netmask 255.255.255.0 ) My apache2 config is not working as expected and I think its due to a networking problem because eth0:1 reports no RX or TX stats: # ifconfig eth0 Link encap:Ethernet HWaddr [removed] inet addr:1.2.3.1 Bcast:[removed] Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:46047 errors:0 dropped:0 overruns:0 frame:0 TX packets:65703 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:6131194 (5.8 MiB) TX bytes:82568335 (78.7 MiB) Interrupt:40 eth0:1Link encap:Ethernet HWaddr [removed] inet addr:1.2.3.2 Bcast:[removed] Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:40 Does anyone know how to get this working? - Grant

[gentoo-user] text in xterm
Folks, I have an interesting problem -- not sure what's causing it. Using xfce4 + compiz -- nothing too fancy. When I open an xterm and start typing, I start getting 'artifacts' (specifically green lines between the various letters I'm trying) in my xterm. The only way to fix this is to either: (a) move the window (doesn't solve the problem if I start typing again in the terminal) (b) resize the window (this will solve the problem for all text present and future entered in terminal) (c) ...uhmm, nothing else I thought it was a font size problem -- my Xdefaults is configured to have some pretty tiny fonts. XTerm*faceName: Monospace XTerm*faceSize: 10 !XTerm*faceSize: 9 Modifying the font size, however, did not resolve the issue. The problem persists. Thoughts / ideas?

On the remote desktop machine, you probably had to add an entry to the SSH authorized_keys file. You can prefix that line with the command that the user is allowed to run. For example (I use rdiff-backup too): command=/usr/bin/rdiff-backup --server,no-pty,no-port-forwarding ssh-rsa big_ugly_key I tried both that and simplified versions of it but it seems to prevent the login from working. It hangs on the following command, which works if I don't add the above: ssh -o PasswordAuthentication=no 1.2.3.4 -l user 'echo -n 1' That's the point? You can't log in (run /bin/bash) or do anything except the command listed in the authorized_keys file. I see what you're saying but don't I need to use the ssh command in order to use the rdiff-backup command? - Grant

If your laptop is currently using 192.168.a.b with a default gateway of 192.168.0.1, then the packets will be sent to the router for routing. And if the router is in the default configuration usual for home users, it won't know there's a 1.2.3.z subnet on your LAN, and it'll be trying to route the packets out into the internet (and those poor little packets will probably get very confused when they reach your ISP and it sends them back again!). You can triple-home by setting eth0:2 to 192.168.c.d, and can (depending on your bridge/router configuration) continue to use private addresses for additional machines if you have more hosts on the LAN than you have globally-addressable IPs.

Re: [gentoo-user] Re: Normal disk speed?
WOW! Those differences are crazy! Please - I know benchmarking takes a lot of time - but could you check something: the behavior those fs have at what time they flush data from cache to disk is very different. Have you made sure that you measured the time it really needs? I mean the difference between: $ sync; time cp source dest and $ sync; time (cp source dest; sync) Only the last measures somewhat correctly. I had noticed that there was, say, 5 seconds of disk activity after the cp command complete which I assumed was buffers getting flushed, but 5 seconds didnt seem that significant overall. I will run the tests as you suggest and post back. Do you think btrfs (with or without compression) would be faster than reiser? If so I will try that as well.

I'm guessing that you are paying a third party (maybe some company similar to rackspace.com) to serve your (two?) websites on their hardware? I'm also guessing that the third party is running apache on their own servers, right? These are newbie questions, but I'm hoping to focus our thoughts on the parts of your questions that seem sorta vague to me. I'm also hoping to learn something along the way, of course :)

Make sure you don't have SSLCertificateFile/SSLCertificateKeyFile defined anywhere outside of the virtual hosts. It was ServerName. I had ServerName defined as www.example1.com in /etc/apache2/vhosts.d/default_vhost.include. I removed it from there and added it to each of my SSL VirtualHost blocks and now everything works. I noticed that removing ServerName entirely works for Firefox, but in that case SSL wouldn't work for either domain in Opera. I thought ServerName was just a label like ServerAdmin. Should I be OK only having it defined in each of my SSL VirtualHost blocks? Thanks a lot for everyone's help with this. You helped me realize it was an apache2 config problem. - Grant

...which exactly copies whatever settings you have there.
Synchronization between CFLAGS and CXXFLAGS becomes automatic this way.
MAKEOPTS=-j 12
Agh No!!! That's probably your problem right there.
The recommendation in the manual is N+1, where N == number of cores. Do
you have 11 or more cores? I find that even that isn't always safe. I
set...
MAKEOPTS=-j 1
and it solves quite a few problems. Note that the final binary is just
as fast, regardless of that setting. The compile speed is somewhat
faster with a higher number. But you quickly lose any time savings
from that, the first time you waste several hours trying to figure out
why something isn't compiling. MAKEOPTS=-j 1 should be mandatory.

To not to pollute the mailing list again with a dozen of outputs and
logs I haven't attached those to this different posting. If you need
a certain file/log/output or whatever to fix this, please let me now!
:)
