Apparently it is fairly common behavior for some IMAP clients to open up multiple connections to the same mailbox. Some times the multiple accesses came from different servers (stand alone IMAP client and a webmail system), but

I am running Dovecot IMAP on Linux, on a LizardFS storage cluster with Maildir storage. This has worked well for most of the accounts for several months. However in the last couple of weeks we are seeing increasing errors regarding corrupted index files. Some of the accounts affected are unable to retrieve messages due to timeouts. It appeared the problems were due to the accounts being accessed

Greetings. If I issue the following sequence of pseudo-syscalls: fd = open(temp_file, O_WRONLY) write(fd) rename(temp_file, dest_file) fsync(fd) close(fd) (where dest_file is in a different directory) Does ext3 order the commit such that the file write effectively happens in the journal before the rename? That is, is there any chance that, if a crash occurred, that the destination

Greetings. If compression is disabled in the sshd config file, and a client attempts to connect with compression enabled, the session fails with the following error message: no matching comp found: client zlib server none This error message is produced on line 285 of kex.c (version 3.4p1). This happens with either UsePrivilegeSeperation on or off, so I do not believe it is a PrivSep issue. Am

Hi! I was just wondering how Ext3 and Reiserfs compare. When I reinstalled my server (because of a stupid hacker) I took the opportunity to change to ReiserFS. And I have to say it's really much faster than Ext3. I don't have benchmarks, but for example, stuff like "make dep" on the linux kernel is much faster (even though I had enabled write cache when I was using ext3). So

Are there any benchmark resultss that meaningfully compare performance of ext2 vs ext3 vs rieserfs vs sgi xfs? What about effect on cpu usage?

Hi. While testing subvolumes in btrfs on 2.6.32.9, I hit a kernel BUG: [ 492.164012] kernel BUG at fs/btrfs/inode.c:4365! The commands to reproduce this bug are as follows: # mount -t btrfs /dev/sda5 /scratch # btrfsctl -S subvol /scratch # date > /scratch/date # ln /scratch/date /scratch/subvol/ ln segfaults, and the bug above is found in dmesg.

There is llvmlite http://llvmlite.readthedocs.io/en/latest/ , but it doesn't seem to support reading individual instructions, based on these docs. I was thinking to make a simple code analysis tool to, for example, find all system calls that have unchecked return codes, but I can't find a binding for any scripting language. And I am averse to writing this in C++. Thanks, Yuri

I'm using OpenSSH-2.9.9p2 on Solaris 8 sparc64. 2.9p2 worked fine, but 2.9.9p2+ is giving me trouble with one thing - sshd segfaults if I try to connect and execute a command, such as "ssh machine ls". Otherwise it works great. sshd will fork, and the child process segfaults. CVS snapshot does the same thing. I've narrowed this down somewhat. It will only happen if you use

With OpenSSH 2.9.9p2 as the server, I'm not able to do scp or "ssh machinename command" in general to any of my Suns! I tracked this down a bit; the problem occurs only when PAM support is enabled. However, if I remove line 430 of session.c, "do_pam_session(s->pw->pw_name, NULL);" inside of do_exec_no_pty, the problem goes away. It looks like the following entry

Hi, all. My subject line says it all: is there a WiFi SIP phone with VPN abilities? Failing that, a WiFi phone that runs Linux? I already know one phone that does meet my requirements -- the iPhone. The new software comes with a Cisco VPN client, and a SIP client can be had from third-party vendors for jailbroken phones. And, while I'm not averse to the idea, a) it ain't cheap, and b)
