Intrusion Detection Systems
Situation: We are providing hosting services.
I've grown tired of the various kiddie scripts/dictionary attacks on
various services. The latest has been against vsftpd, on systems that I
can't easily control vs. putting strict limits on ssh. We simply have
too many users entering from too many networks many with dynamic IP
addresses.
Enter.... thinking about LIDS or Log Based

Random Proliant Crashes CentOS 6.1
I've been seeing some random Proliant DL380 G4 64bit crashes. Each time,
on the console are messages relating tojbd2/cciss and something about a
waitfor 120 seconds. Is anybody else seeing anything like this? Oddly, I
can't seem to find this in the logs. I guess it can't write when this
happens.

Now you have my curiosity aroused. Was this with CentOS3 or 4, ie LVM
or LVM2? What problems?
We use LVM on all our RH9 setups at work. No problems at all.
OTOH, LVM2 is a work in progress that

CentOS 5.6 PHP 5.3 and SquirrelMail
OK, so I did an upgrade to PHP 5.3 on one of my servers. I noticed the
uninstall of php also removed SquirrelMail and it won't install under
PHP 5.3. Has anybody worked this out with a good RPM or repo solution?

Bind Firewall Rules
OK, so does anybody have a good firewall rule solution for what we're
supposed to be doing with bind these days? Obviously port 53 is no
longer enough.

CentOS 4 Dovecot Problem
For those of you that still are running CentOS 4... I have one system
that is still going... there is a problem with the newest release of
Dovecot under mbox. Certain spam is causing this error when users try to
log on.
file lib.c: line 37 (nearest_power): assertion failed: (num <=
((size_t)1 << (BITS_IN_SIZE_T-1)))
Rolling back to a previous release fixes these issues. I'm not

Criteria:
security

Preferably something living under one of the better repos, such as epel
An active project doing updates and adding features.
I don't suppose any of you have ideas for this? ;)

RE: CentOS Digest, Vol 2, Issue 13

I have ecommerce stores on my server who use the same instantssl certificate

We got it working. It was a custom config problem for that one site.

CentOS 5 and bittorrent
Folks. This is likely to be the hardest hit CentOS has ever taken with
regards to bandwidth needs.
I was really hesitant to use bittorrent for this type of thing for a
long time. However, it really is nice to give back at least what you
take. At the moment, I'm seeing almost 3000 connections to the torrent.
That times 3.5 gigs is a pretty huge chunk of data... and it has just begun.

Bind Issues
I'm running bind in a chroot environment. It seems that since the Redhat
snafu which wrecked bind (yes, I had caching nameserver running as well
but not anymore) I have been having problem with my slave nameservers
retrieving updates from the master.
Looking at the zone records, some are owned by root, some are owned by
named. I'm now confused as to what the ownership should be and

Logwatch with Postfix and Amavisd-new
I'm trying to get usable reports out of logwatch on this new system.
Looks like the reports are running in an 'unformatted' mode under
Postfix/Amavisd.
I found a couple of programs, postfix-logwatch and amavisd-logwatch.
These sound promising. I am running Amavisd as the frontend to Postfix.
Is anybody running either of these as a logwatch filter?
If so, is it repetitive to run

Changing Console Display Settings
Hmm.. after all these years I actually have a monitor on my desk beside
me going through a couple of KVMs to our racks. So, I hope to make more
use of direct console connections instead of shelling in.
But, now.... the text has always been huge and the interface clunky. And
after a bit of googling around, and file searching on the system, I
can't seem to find where or if there is a way to

First SSH now VSFTP
Seems the script kiddies are now hitting vsftp with dictionary attacks.
I had three boxes showing around 12000 attempts from one IP yesterday.
My thoughts are that there should be an upstream solution for this which
is then supported by the upstream vendor. Yes, I know there are several
'other' solutions, but I'd really like to stay mainstream and use a
supported method for

Samba and Scalix
I'm hoping to integrate a shared folder(s) so that we may be able to
drag and drop files from various OSs into a shared folder on a
CentOS server which can be accessed via Scalix SWA or some other email
client.
Maybe I'm totally off base with how Scalix stores files in public
folders... maybe everything has to be in mbox format for all folders and
this could never work.....
Anyway, I

vsftp
I'm having an odd behavior with vsftp on all CentOS 4 servers... maybe 3
too, but I'm not on those much.
I am transferring in port mode as I've never managed to get passive to
work with a firewall running.
Anyway, this is what happens.
During normal transfers with few files.. it works perfectly.

CentOS 4 snag with htaccess
I'm hitting a snag with htaccess. Have created .htaccess and .htpasswd
files, set up apache directory options just like always... the exact
same setup works fine on CentOS 3, but I can't seem to get it to
authenticate on CentOS 4? Am I just being blind stupid (as in not seeing
something 'exactly the same') or is there something different I'm
missing? I have selinux running

saslauthd attack
I'm seeing a lot of activity over the last two days with what looks to
be a kiddie script. Mostly trying to access several of our servers with
the username anna. All failed... in fact I don't think we have a user
anna on any of our servers. Meanwhile...
I'm running Sendmail. This pertains to Centos 4 and 5 servers. I'm also
running fail2ban on some and Ossec on others. So far,

Centosplus
Are there any gotchas with doing a MySQL5 upgrade from the centosplus
repostitory? Can this be done as an update via yum or do I need to
uninstall and the install? There wasn't anything on this in the

htaccess htpasswd and satellite connections
Yeah, maybe this is a bit on the edge....
I am discovering several issues with users on satellite internet
connections not being able to authenticate via a htaccess/htpasswd
system. Some users cannot connect at all, some can connect reliably..
and some are hit and miss.. works one day and not the next. Yet those
same users can log in fine if they switch back to their dialup system.
