Firefox slower on GMail since update to CentOS 5.5
by Mathieu Baudier 01 Jul '10

01 Jul '10

Hello, since I upgraded from CentOS x86_64 5.4 to 5.5, I noticed that Firefox has become significantly slower on GMail (or Google Apps Mail). The page becomes slow to scroll as soon as there are more than a few mails in a conversation (like in a typical CentOS mailing list thread). Did anyone else notice that as well? (I guess that I'm not the only GMail user around) Could I have missed something / do something wrong? More details: - I did a fresh install from the 5.5 install DVD, keeping only the home directories - I'm using the Nvidia driver from elrepo (but I had the pb also with the default driver) Cheers, Mathieu

How can binaries be different when package versions are identical? (mkfs.ext3 on CentOS 5.4)
by Aleksey Tsalolikhin 01 Jul '10

01 Jul '10

Situation: two similar servers, both with CentOS 5.4 64-bit. Making an ext3 filesystem on one takes seconds, on the other minutes. Partition Size Server 1 Server 2 1 GB 0.7 sec 0.3 sec 4 GB 2.5 sec 1.2 sec 40 GB 15 sec 13 min WTF e2fsprogs RPM is e2fsprogs-1.39-23.el5 on both systems mkfs --version reports "util-linux 2.13-pre7" on both systems mkfs -V reports the same on both systems (mke2fs 1.3 (29-May-2006) Using EXT2FS Library version 1.39) file size on mkfs and mkfs.ext3 binaries is identical However, checksum on these binaries differs across servers, and "cmp" reports files are different I took "mkfs" and "mkfs.ext3" from server 1, put them on server 2, and got an improvement: 40 GB 15 sec 3 min Just out of curiousity, I ran "rpm -V e2fsprogs" to see if rpm would pick up the difference and sure enough, it complained mkfs.ext3 changed. Both of these servers have CentOS 5.4; Server 1 was installed in Dec 2009, Server 2 in April 2010. I'd like to: (a) account for the difference in the binaries, and (b) see if something else is different that I can make the same to get the mkfs.ext3 time down to 15 sec on both systems. Solving (a) should shed light on (b). Any ideas? Best, Aleksey

Live CD problems
by drew einhorn 01 Jul '10

01 Jul '10

Hi, I'm trying to repair a remote system using the Live CD. I have VPN access to the subnet where it lives. An onsite person is booting from cd, and running a small script I provided to tweak the default firewall rule set to allow incoming ssh, and set a password for the centos user and start sshd so far so good I can remotely access the system. the problem is the live cd environment is very fragile. I need to rebuild the contents of a couple filesystems, so I need to umount them and remount them rw. If I make a mistake in a mount command instead of giving an error message and letting me try again. The system freezes and any other ssh session freezes, ahnd will not accept any more incoming ssh connections. the only way I have found to recover is have the onsite person reboot from cd and rerun the script allowing incoming ssh again. Hmm. I should try to talk the onsite person through trying something else from the console. Argghhh!!! This is more than just an annoyance. -- Drew Einhorn "You can see a lot by just looking." -- Yogi Berra

Grub fails on dell optiplex 320

After reading: *[1] http://forums.fedoraforum.org/showthread.php?t=141178 *[2] https://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=2… forum=39 *[3] http://wirelessness.wordpress.com/2007/02/07/installing-fedora-linux-on-a-d… ptiplex-320/ *[4] http://lists.us.dell.com/pipermail/linux-desktops/2007-January/000148.html 1. I booted with linux rescue 2. chroot /mnt/sysimage 3. yum upgrade 4. reboot 5. 2.6.18-194.3.1.el5 6. hang... Per [4] this should have been fixed in 2.6.20 (2007), did this get back ported by the upstream? The LILO solution wont work because we have to use LVM.

I get an email from security, I see the article on slashdot, and other places, that Adobe's issued an update to acroread... but yum update AdobeReader_enu is still telling me there's no update. Has anyone seen it yet, in the repositories? mark
