Dovecot doesn't read users and passwords from config files
Greetings,
I am setting up Dovecot 1.0.15 on my home Fedora Core 8 pc ONLY to
access my mail archives across several mail clients. No access from
the internet is possible or needed here.
I cannot log in with any client, the login always fails. The reason,
as I understand, is that when dovecot starts it doesn't read any user
name from the userdb file, so when I try to login it doesn't

-z and -B65536 causing file corruption in 2.5.5 w/zlib 1.1.4
When using the -z and -B65536 options together, sometimes there is file
corruption. Client and server are both compiled against zlib 1.1.4, so
the gzip corruption shouldn't be there, right?
With -z and -B32768 there is an error, but it is detected in a different
way.
With -B65536 and without -z all seems to be going OK.
With -B16384 and with -z all seems to be going OK.

Roaming profiles, W2K and Samba PDC.
<expletive deleted> My roaming profiles keep "forgetting" they exist on
my W2K boxen. It doesn't occur server-side, as other W2K clients log in
fine. But, once one of the clients has forgotten about roaming profiles,
it usually takes a re-install to make it remember them... and then, only
temporarily. (Except on one machine that's worked fine from the get-go.)

Error: file_dotlock_create failed: Permission denied
Hi,
I have a Fedora 14 x86_64 computer. I run dovecot 2.0.12 on it, only to
keep a local imap copy of all my email, in maildir format. A couple days
ago the hard disk broke, so I bought a new one, and reinstalled Fedora 14
x86_64 with all the updates.
Then I copied all the maildirs from a backup to the new drive.
But I can't access email now. No matter how I change sticky bits or
ownership

Kernel panic on Dell 1850
I'm attempting to upgrade to kernel-smp-2.4.21-27.0.4.EL (x86_64) on a
Dell 1850. The new kernel is panicing on reboot. When comparing
against the current working kernel, I just noticed that we're currently
running the "UP" kernel:
[root at polaris root]# uname -srvp
Linux 2.4.21-27.0.2.EL #1 SMP Wed Jan 19 11:49:43 CST 2005 x86_64
First question... why is the kernel

Disconnecting: protocol error: rcvd type 98
When I SSH using protocol 1 from a Debian box running OpenSSH 2.9p2-4
to a sparc.sunos5 box running vanilla OpenSSH 2.9.1, after a little
while (of inactivity?) I get the following message on the client
terminal:
Disconnecting: protocol error: rcvd type 98
Looking further, this message is actually caused by the SSH daemon.
However, I'm at a loss to determine why sshd is doing this.

Thanks for the sharing. If that doesn't bother you too much, I would like to
know auto-parallelization benchmarks. :p
Just curious. I was thinking that

[PATCH v5 3/6] libnvdimm: add dax_dev sync flag
This patch adds 'DAXDEV_SYNC' flag which is set
for nd_region doing synchronous flush. This later
is used to disable MAP_SYNC functionality for
ext4 & xfs filesystem for devices don't support
synchronous flush.

[PATCH 1/2] ext4/xfs: add page refcount helper
There are several places where ZONE_DEVICE struct pages assume a reference
count == 1 means the page is idle and free. Instead of open coding this,
