Sendmail error: auxpropfunc error invalid parameter supplied
I just noticed this error in my messages log after restarting sendmail.
The only change I have made is
1) manual fix in /usr/share/spamassassin/72_active.conf
2) sa-update (several times)
Now the mail is not running ok, my mail queue keeps growing.
Regards,

Old hd, new machine
What should I do to make an existing CentOS (5.4) disc boot up on a new
computer?
I just made on CentOS 5.3 installation on that machine, so I know the
hardware is compatible.
Would it be enough to boot with a DVD in rescue mode, or boot with
another hd, and install grub?

L9 - what is a value
This code:
var('i') = string;
boolean($i); '<br>';
var('i') = array;
boolean($i); '<br>';
gives:
> false
> true
So an empty array gives "true" but an empty string "false".
This is different from L8. Is this intentional? If so, why?

Fsck on mdraid array
Something seems to be wrong with my file systems, and I want to fsck
everything. But I cannot.
The setup consists of 2 hds, carrying 3 raid1 (ext3) file systems (boot,
/, swap). OS is up-to-date CentOS 5.
So I boot from CentOS 5.3 dvd in rescue mode, do not mount the file
systems, and try to run
fsck -y /dev/md0
fsck -y /dev/md1
fsck -y /dev/md2
For each try I get an error message:

Disk quotas for Sendmail
Hi,
CentOS 5.x, Sendmail 8.13.8.
I would like to start using disk quotas on my Sendmail server, and optimally
they should be configurable by user or group. How can this be done? (I tried
to google, but no success.)

Feed a list of filenames to vim
There are some googlable ways to feed a list of filenames to vim, but I
stumble on weird results.
With my filelist, I try to do
cat list | xargs vim
...to edit the files listed in the file "list". Here's what happens:
[root at lasso2 tempdir]# ls -l
total 8
-rw-r--r-- 1 root root 0 May 17 18:28 a
-rw-r--r-- 1 root root 0 May 17 18:28 b

Installing 4.4 - problem on 386
I tried installing with several options (noacpi noapm; noprobe; noprobe
skipddc noacpi noapm nodma). Always I get the same error.
BUT this is not in fac a CentOS problem at all, because I get the same error
always when I boot from hd (Fedora Core), IF there is a CD in the CD-ROM
drive. (I tried with CentOS 1/4, CentOS 2/4 and a HP printer software CD.)
It must be something with the CD drive!

Hard disk, format, filesystem
Ok, I give up... I have to ask. This is CentOS 5.
I switched one of my raid1 disks, and I already thought I had succeeded. But
now it seems that something is very wrong with the first partition on the
new disk. Luckily my system is fully bootable with the other disk.
Here's some info. The new disk is sdb.
// I removed all partitions with parted, and created the first one again.

Retrieving POP mail from server to server
I need to transfer a client's email inbox from another mail server to
our mail server (Centos 5). This is needed once only (or maybe a couple
of times).
What is the best command-line tool? Fetchmail?
I did this once before, with another tool, but have forgotten.

Openwebmail emergency (Perl)
After system update yesterday, Openwebmail now gives an error:
> Undefined subroutine &Compress::Zlib::memGzip called at /var/www/cgi-bin/openwebmail/shares/ow-shared.pl line 1175.
I tried to do
perl -MCPAN -e shell
install Compress::Zlib
But it says Compress::Zlib is up-to-date. What do to?? I cannot find an
answer by googling.

[OT] List of all email users
This is not CentOS-specific, hence OT.
I need a list of all email users on my system (there are hundreds of them).
The list could be extracted from /etc/aliases and the virtusertable.
Does anyone know of a script that would do this automatically? It would have
to
- exclude commented-out lines (of course)
- exclude duplicates
- produce a list of usernames (or maybe unresolved email addresses for

Can I combine VMWare ESXi (free version) virtualization and CentOS

KVM resources?
Later this week I will have to install a serious KVM setup, and I am
looking for background material.
I found a nice how-to:
http://wiki.centos.org/HowTos/KVM
...but it is probably partly outdated by now.
Then there is a fine virtualization manual:
http://www.centos.org/docs/5/html/5.2/Virtualization/
...but it seems to be only for xen.
I plan to use either CentOS 5.6 or Scientific Linux

File sharing solution
I would like to offer my isp clients a solution for sharing (big) files,
basically on one-to-one basis. This is how I imagine it:
- an anonymous or registered user can upload a file
- on response (s)he will get a file-specific (or batch-specific)
username/password
- (s)he can send a link and un/pw by email
- the receiver can download the file
- the file will be automatically deleted from the

ls and rm: "argument list too long"
Since when is there a limit in how long directory listings CentOS can show
(ls), or how large directories can be removed (rm). It is really annoying to
say, for example
rm -rf /var/amavis/tmp
and get only "argument list too long" as feedback.
Is there a way to go round this problem?
I have CentOS 5.2.

Identifying physical disks
I am sure this is really simple.
I have a setup of 2 disks (sda, sdb) which are outwardly identical, and
are mirrors of each other. Together they form 3 raid1 devices. Both
disks can boot.
Now sda has bad sectors, and I should replace it. But which one of the
physical disks is sda??
The machine boots fine from either one of the disks, (and the booting
disk of course is always called sda).

Vim scripting - cursor motion
I am working on my first vim script. The script is supposed to do some
find/replace on a file, then save the file with a new name and quit vim.
I will save the script in a file and then call it from a bash script
like this:
vim path-to-the-file -s path-to-my-script
Maybe I have not found the right resources. I can find/replace with
expressions that are similar to those I use manually, for

Sendmail with TLS, permission problem
Hello, list,
I have a problem with Sendmail configuration.
I'm building (on CentOS 5) a "dual-MTA" setup with amavisd-new (as specified
in amavisd-new documentation, file README.sendmail-dual).
So far so good. But when I tried to add server SMTP-AUTH and TLS, I get a
strange, permission-related error, and STARTTLS will not start.
In my .mc conf, the Sendmail user is now the usual

KVM, virsh attach-disk error
I try to add a fresh, unformatted disk partition to a KVM guest. I

On the host I write:
