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.) - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. & fax +358 9 493 981 * Mobile +358 40 771 2098 (only sms) jussi.hirvi at greenspot.fi *

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. // parted

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!

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. - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15

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

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? - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358

[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

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

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. - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki *

Openwebmail dependency problem
Ok, I have to ask. I tried to yum install the latest openwebmail (from the openwebmail repo), and got a transaction check error about a conflict with some packages which are needed by amavisd and spamassassin (packages originating from rpmforge, I think). Below is the yum output. By googling I found a lot of descriptions of the problem, but no solution. - Jussi (...) Resolving Dependencies

VMware vSphere Hypervisor (free ESXi) and mdraid
Can I combine VMWare ESXi (free version) virtualization and CentOS mdraid level 1? Any pointers how to do it?

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:

Yum loses memory when kernel is upgraded
Centos 5.x Why could this be? After I loaded a xen kernel (by mistake), yum seemed to lose its knowledge of my CentOS version. I had that fixed by "yum install centos-release" (I had first to fix the repo addresses for this to succeed). But after that, I noticed that yum did not remember anymore, what packages were already installed. It seems that the something happens to the rpm

Mailman - searchable archive
Mailman works well for our mailing lists, but the archive is unacceptable - the worst thing is lack of search function. I got one tip for this: 1) emails converted to html format with mhonarc 2) search can be done with htdig Opinions? Maybe there are better software solutions for this - I hope. - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9

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. - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250 Helsinki * Finland Tel. +358 9 493 981 * Mobile +358 40 771

Not firewall, but what?
I have a strange problem, where some clients see the website on my server and some do not. It is not about the iptables, and seems to be not about tcp wrapper. Still it is something within the box. More details: - the problem is only with some clients, with no geographical connection between them; other clients see the website just fine - the problem-clients get timeout with their browser -

Virtualization platform choice
Some may be bored with the subject - sorry... Still not decided about virtualization platform for my "webhotel v2" (ns, mail, web servers, etc.). KVM would be a natural way to go, I suppose, only it is too bad CentOS 6 will not be out in time for me - I guess KVM would be more mature in CentOS 6. Any experience with the free "VMware vSphere Hypervisor"?. (It was formerly

Per-user limits for port access
Centos 5.x again... Is there a way to limit port access on a per-user basis? My practical goal is to limit, who is allowed to use SMTP AUTH in Sendmail. Any possible solutions appreciated... Obviously, limiting by ip will not work, since the very purpose of SMTP AUTH is to enable mail relaying for trusted users from *anywhere*. - Jussi -- Jussi Hirvi * Green Spot Topeliuksenkatu 15 C * 00250

Migrating standalone systems to KVM
A while ago I got great instructions from Pasi for migrating standalone systems to *xen*. However, now I have decided to use KVM instead, which raises a new question: How to migrate a standalone system to *KVM*? I know a two-step way to do it: standalone system -> xen pv guest xen pv guest -> KVM pv guest I read that xen -> KVM migration is trivially easy. But is there an easier
