I had sent email to Andrea asking him if his blkdev-in-pagecache might cause the recent reports about ulimits being applied to block devices. This is his response which he asked me to forward to ext3-users since he can't post being a non-subscriber BTW, Redhat should whitelist various kernel hackers email address on their mailserver so that they can post freely to various lists Regards,

postfix-users seems to be a subscription only list. I'd recommend incorporating TDMA <http://tdma.sf.net/> to allow for easy discussion by outsiders Andrew Morton (of ext3 fame) had sent this message to postfix-users list I am forwarding so that Wietse can hopefully provide the definitive answer to the question Andrew Morton/Stephen Tweedie seek ----- Forwarded message from Andrew

Hi, I am using openssh 2.1.1pl4 on a Linux 2.2.16 box [RH 6.1 distribution], I was confused as to why when I telnet into that box, I get /usr/local/bin in my PATH but when I ssh into my box, /usr/local/bin is not in my PATH I modified /etc/ssh/sshd_config to have UseLogin yes and then when I try to ssh into that box, I couldn't. ssh -v showed the following debug: Requesting shell. debug:

A playback of a mono vorbis track on a system using the i810 audio driver via ogg123 results in a double speed playback (chipmunk sound). It seems that this chipset doesn't support mono and while xmms seems to compensate for it, ogg123 doesn't I have a bugzilla report at redhat.com filed on this with more details https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=90433 Regards, Yusuf

Postfix <http://www.postfix.org> does a chattr +S on its spool directory when it is installed on Linux. This is what is written in the postfix startup script -- # # LINUX by default does not synchronously update directories - # that's dangerous for mail. # if [ -f /usr/bin/chattr ] then CHATTR="/usr/bin/chattr +S" else CHATTR=echo fi -- Is this still required on ext3 ?

That seems to be the indication given by this webpage http://www.zip.com.au/~akpm/linux/ext3/ext3-usage.html However, default install of Redhat 7.2 setsup fs_passno(6th field of /etc/fstab) as 2 which asks you if you want to run fsck after an unclean shutdown The question is, is fsck required after an unclean shutdown or should one just rely on journal replay. What does fsck do when it sees an

Hi, I have the following line in $HOME/.ssh/config Protocol 2,1 I run OpenSSH 2.3.0p1 on my RH 7.0 box running 2.2.18. I am trying to ssh into a FreeBSD 4.2-stable box which runs OpenSSH 2.2.0.

Hi, I am using Redhat 7.3 which comes with openssh 3.1p1. I am running an antivirus software called vexira on this server. It starts of 2 daemon processes in the background. Whenever I stop/start these daemons in an ssh session, it hangs. I added "shopt -s huponexit" (without the quotes) in /etc/bashrc, but the hangs still occur. Any advice on this would be appreciated Regards, Yusuf

man chattr mentions the following [on RH 7.2] A file with the `i' attribute cannot be modified: it cannot be deleted or renamed, no link can be created to this file and no data can be written to the file.

My reading of the kernel.src.rpm doesn't indicate that Severn has ext3 htree patches. Stephen, were there any issues seen during Cerberus testing ? Regards, Yusuf -- Yusuf Goolamabbas yusufg@outblaze.com

I found that my mail client reported invalid messages in the just-downloaded rsync.mbox. Further examination showed that they are due to instances of unprefixed words "From" at beginning of line in the message body. Once I fixed them, all messages are visible. It looks like the rsync.mbox file may have been prepared by simple concatenation of messages, without the filtering of

[Jim, as coreutils developer, this might interest you] In libguestfs we run some quite detailed checks of the output of the statvfs system call for our tool "virt-df". I noticed that the output of virt-df changed slightly. Narrowing it down, the difference only happens between: Fedora kernel 3.2.0-0.rc0.git4.1.fc17 (3rd Nov) Fedora kernel 3.2.0-0.rc1.git2.1.fc17 (11th Nov) With

Hello, recently Theodory Tso posted a patch for the ext2fs driver, which improves speed of find and similar programs. Background: the application access all entries in the directory in the order they are stored on the disk. The current ext2 (and apparently Ext3) run a lookup function for each readdir call, starting with the first node! Theodore stores a refference to the node which was accessed

Commit 4490001029012539937ff02778fe6180613fa949 ("virtio-net: enable multiqueue by default") blindly set the affinity instead of queues during probe which can cause a mismatch of #queues between guest and host. This patch fixes it by setting queues. Reported-by: Theodore Ts'o <tytso at mit.edu> Tested-by: Theodore Ts'o <tytso at mit.edu> Cc: Neil Horman <nhorman
