Re: [CentOS] amazon ec2 and centos?
We're currently running almost 20 instances with aws. We're using CentOS 5.4/5.5 as the base, and the 2.6.18 kernel image provided by amazon in the form of their 2.6.18-ec2-v1.4(may have that form wrong). This works well, but its also from December 2009 so we're 6 months off where Cent is now. Be more than willing to help QA/Test out kernels if there's some way we can get them submitted into Amazon's kernel store. Anything we can do to help, feel free to contact off list. Would love to see a much quicker turnaround on these, and might help get us to Amazon supporting CentOS 6 quicker down the road if we get the process in place with them now with 5.5. Cent works very well other that this kernel process. Cheers J.G.

I found that while all of upstream's kernels on ec2 seem to be marked as paid, another rebuilder of upstream, Oracle, has kernels and initrds out there for free. I just grabbed the appropriate kernel-xen from OEL and installed it, and my hand-rolled Centos5.5 image booted off their aki/ari without any problems.

[CentOS] MAC address changes after cloning
Hi, I have x86 system and have used clonezilla to clone the entire hardisk of system A and restored it on another x86 system, system B. After the cloning process, i notice that the MAC address of the system B in the /etc/sysconfig/network-scripts/ifcfg-eth0 is changed and is having the MAC address of system A. The interesting part is that if i do an ifconfig from the bash prompt, the MAC address of the system B is correctly displayed, but in ifcfg-eth0 script it is different. I had disabled kudzu, since i was always getting eth1 activated on System B, even though i had used eth0 on system A. eth0.bak was getting created instead on system B. Disabling kudzu resolved it. My question is that how could i get the same MAC address for system B from ifconfig and in /etc/sysconfig/network-scripts/ifcfg-eth0. Is there any script to do it ?

[CentOS] SOLVED annoying firefox crash on nvidia
A long time ago, there was thread about firefox randomly crashing. http://www.mail-archive.com/centos@centos.org/msg50010.html It turned out not only firefox, but random other X window applications as well. Especially scrolling in firefox seemed to induce the error. I'm now since almost 2 weeks up and running with the same firefox instance and scrolling up/down, left/right, playing video's, viewing websites with heavy javascripts whatever, and without any crash since. I use the proprietary driver NVIDIA-Linux-x86_64-195.36.24-pkg2.run (the latest last time I looked). I believe the cullprit was to explicitly load some modules in the xorg.conf file. (It is probably the "extmod" module -- there is almost no real documentation on what those modules actually do...) While the nvidia driver installs, there is an utility that generates the new xorg.conf file for you, having only one module "glx" loaded. This seems to be source of the trouble. Gnome seems to assume more functionality is available, and does not gracefully recover when asking something that is not implemented in those extra modules. Since adding some more modules, I have no more crashes: Section "Module" Load "dbe" Load "extmod" Load "type1" Load "freetype" Load "glx" Load "fbdevhw" Load "record" EndSection And, as added benefit, or side effect, the memory usage of my gnome applets has drastically gone down. I used to see a simple clock-applet having using 800 Mbyte virtual memory or so and having 400M reported under the "resident memory" column. Other people also reported such a problem, but it was frequently dismissed by explanations like "gnome uses a lot of shared memory it is not real memory". I now have my clock and other gnome applets running in under 300M virtual, 10-14M resident memory (if you ask me, still large for clock -- where is the time when I ran a whole unix with 5 serial terminals and the server had 1 Mbyte RAM total memory on a motorola 68010 processor?) -- Paul Bijnens *** * I think I've got the hang of it now: exit, ^D, ^C, ^\, ^Z, ^Q, ^^, * * quit, ZZ, :q, :q!, M-Z, ^X^C, logoff, logout, close, bye, /bye, ~., * * stop, end, ^]c, +++ ATH, disconnect, halt, abort, hangup, KJOB, * * ^X^X, :D::D, kill -9 1, kill -1 $$, shutdown, init 0, Alt-F4, * * Alt-f-e, Ctrl-Alt-Del, Alt-SysRq-reisub, Stop-A, AltGr-NumLock, ... * * ...

Re: [CentOS] MAC address changes after cloning
The MAC address shown in the /etc/sysconfig/network/ifcfg-ethX files is just the address of what was detected at the time of installation. This is done to make sure the configuration is applied to the correct NIC. It does not auto-generate every time you reboot the system. You will need to manually change that to the MAC address displayed by ifconfig, and add that to the list of things you need to update after cloning a system.

It's a grub thing - the entry for what it's booting needs a line reading root (hd0,0) or whatever is appropriate.

[CentOS] PHP file upload limit
Hi all, I am trying to run a web-based PHP application on a CentOS 5 32-bit machine that requires me to upload large files. The machine also happens to have little RAM (256MB). I have no problem setting my upload limit ( upload_max_filesize ) to 1 GB but for some reason 2 GB or above seems to be no go. Would anybody know why? Could it be one of the many 32-bit vs 64-bit issues? Thanks. Boris. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Could it be one of the many 32-bit vs 64-bit issues? upload_max_size is not the only variable that would affect uploading. You may also want to look at the settings for: post_max_size -- uploading files is done through the HTTP POST mechanism so this has to be at least as big as upload_max_size memory_limit -- If memory limits are enabled, this also must be larger then upload_max_size It may also be a 32bit limit as well: (from php.net) Note: PHP allows shortcuts for bit values, including K (kilo), M (mega) and G (giga). PHP will do the conversions automatically if you use any of these. Be careful not to exceed the 32 bit signed integer limit (if you're using 32bit versions) as it will cause your script to fail. -- Drew "Nothing in life is to be feared.

[CentOS] Intel ICH10R on CentOS 5.4
Hey there.. I was wondering if anyone could share experiences they have had with the Intel ICH10R SATA controller? I tried looking around but all I could find were RAID references, I have no interest in using the RAID functionality just basic SATA JBOD. Wondering if there are any gotchas for performance, drivers, quality etc. I normally don't touch anything that is not hardware RAID though this is a special project.. And even if I get demo gear I won't have enough time to put it through real paces(likely need weeks) before a decision needs to be made. I don't see anything that is causing alarm but just curious if anyone else has experiences. thanks nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I have the GA EP45-ud3r MB with this north bridge. Mine has 3 separate Bios entries for ahci, raid, and jmicron. IIRC C5.4 has drivers for all. The worst thing you can do is install with the functionality off in the bios. Turn them all on, install, then decide if you want to tweek. I never ran JBOD, but did try RAID0 and it was flawless.
