TLS communication director -> backend with X.509 cert checks?
Hello,
using Dovecot 2.2.9 and a setup with directors and backends.
The communication between directors and backends needs to be TLS
secured.
The director config contains a list of hostnames for the backends.
(implicit list because of multiple A/AAAA records for a single hostname
or explicit list of several host names)
On connection setup from a client the director connects to the
selected

Dualstack IPv4/IPv6 setup with directors
Hi,
still using 2.2.9, I've two directors, and these directors
use both IPv4/IPv6 addresses.
`host directors.<domain>` returns one A and AAA for each
of the two directors:
directors.<domain> has address 149.x.y.96 (director1)
directors.<domain> has address 149.x.y.97 (director2)

dovecot as proxy and verification of the backends certificate
Hello,
I'm using a dovecot as proxy, connecting to one or more backends.
The backends use X.509 certificates.
The proxy's passdb returns
extra fields:
user=foo
proxy
host=backend1.<domain>
ssl=yes
nopassword=y
Thus the proxy connects to the backend but can't verify the backends
certificate.
The following comment suggests using ssl_client_ca_file for

Memory leak in ocfs2/dlm?
Hi!
Seems we're facing some memory leak here. This is vanilla 2.6.19-rc6
on a x86_64 box, 4GB RAM.
A simple `ls -Rn' on a filesystem with lots of files makes the box
leak so much RAM that the OOM killer starts to kick in. With slab
alloc debugging turned on, we see this:
# mount; ls -Rn; wait some seconds; Ctrl-C
[root@lnxp-1038:/backend1]$ cat /proc/slab_allocators | egrep

R 4.0.0 rebuild status
Over the last several days, I've been working hard to get all of the Fedora
R packages rebuilt against R 4.0 in rawhide (in the F33-R-4 side tag). With
the exception of R-biomaRt, R-BSgenome, R-GenomicAlignments, and
R-rtracklayer, I believe everything is built and updated to the latest
versions. And of those packages, they're all ready to go when Fedora
infrastructure is working reliably

smbclient Version 4.13.2 Crashes on Fedora 33
Have been working this on the BackupPC users and Fedora mailing lists,
but it's looking more like a general problem in Samba utility, 'smbclient.'
BackupPC is a backup server package that uses Samba, rsync, and other
protocols to backup clients, including Windows PC's. Basically, it runs
a command like this for a SMB backup of a PC:

Using both starttls and ssl in passdb on proxy results in timeouts
Hi List,
I have a dovecot which proxies to different backends depending on an entry in a mysql-database. The mysql-query sets ?ssl? to ?any-cert? and this works fine. But this causes me a problem: sieve-backends only support STARTTLS and if I set ?ssl? to ?any-cert? (or yes), it will attempt a TLS-connection to the sieve-backends, which fails.
My attempt was to alter the query to include

syncing huge files/devices: bmapfs
Hi,
recently I had to sync really huge files (VM images), represented
either as block devices (on one or both sides) or as regular files.
It *seemed* that Rsync didn't work well with block devices (the
--copy-devices didn't 'work for me, maybe I'm stupid or it's broken in
the Rsync that ships with Debian bullseye). And additionally I ran into
performance and resource issues

extending rails via /lib - problems
I wanted to group some functions which I use in some models in one
place. Controllers have application.rb and views have helpers but I
couldn''t find anything about models. Using the /lib directory seemed to
be the only way.
Alright... so I have something like this:
/lib/code.rb
class ActiveRecord::Base
def method_a(n)
.......
end
def method_b(n)
........
end
end
