I'm getting literally hundreds of lines in my daily logwatch (under Centos-5.5), reading --------------------------------------- NULL security context for user, but SELinux in permissive mode, continuing () --------------------------------------- These began when I started running fail2ban (with shorewall), though that is probably a coincidence. In any case, what does this line mean, and

Every few days I see in the logwatch on my Centos-5.5 web-server what seems like a rather feeble break-in attempt. Eg today I see --------------------------- 403 Forbidden /phpMyAdmin/scripts/setup.php: 2 Time(s) /phpmyadmin/scripts/setup.php: 2 Time(s) 404 Not Found /PMA2005/scripts/setup.php: 1 Time(s) /TRAD_files/datestamp.js: 1 Time(s) ...

It seems there was some kind of attack against dovecot on my server (CentOS-5.5) with a hundred or so logwatch entries like: ========================================= **Unmatched Entries** dovecot-auth: pam_succeed_if(dovecot:auth): error retrieving information about user admin dovecot-auth: pam_succeed_if(dovecot:auth): error retrieving information about user webmaster

I'm trying to install spamassassin on a postfix/dovecot server, running CentOS-6.4, following the instructions at <http://wiki.centos.org/HowTos/Amavisd>. I think I have taken all the steps indicated, and the configuration seems to pass the tests suggested, although the response is much more sparse than that described: ------------------------ [tim at alfred ~]$ telnet localhost 10024

Is there any point in running NetworkManager on a server? The IP addresses of the two server NICS are fixed (192.168.1.2 and 192.168.2.2 .) I'm not clear if it is necessary in some way to run NM on a CentOS system? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

I'm getting the following warning in my logwatch, or if I restart the spamassassin service. I've tried yum-reinstalling the packages involved but that didn't help. ------------------------------- /etc/cron.daily/sa-learn: Subroutine IO::Socket::INET6::AF_INET6 redefined at /usr/lib/perl5/5.8.8/Exporter.pm line 65. at /usr/lib/perl5/vendor_perl/5.8.8/IO/Socket/INET6.pm line 16

Has anyone succeeded in installing CentOS-6.0 by PXEboot. If so, would you say how you did it, please. I tried (on an HP MicroServer), but gave up in the end and used a USB stick installation instead. But I'd be very interested to know how to do it, for the future. Unfortunately I didn't keep a proper note of my PXEboot attempt, but IIRC the problem was that install.img was not found,

Does anyone know if the program stunbdc, which prints one's IP address, is available in CentOS-5? It comes with the libnice package in Fedora-11. ------------------------------ [tim at rose ~]$ stunbdc -4 stun.ekiga.net Server address: 75.101.138.128 port 3478 STUN transaction started (timeout 600ms). STUN unknown: 0 mandatory attribute(s)! Received 88-bytes STUN message No

I wonder if anyone has CentOS-6 working on an HP MicroServer? I'm having a problem with the graphics driver for the Radeon HD 4200 graphics card. CentOS-5.6 is working fine on this machine; but at present I only have CentOS-6 running in text mode. The graphics card as given by "/sbin/lspci -m" is ------------------------------- 01:05.0 "VGA compatible controller"

I've been following the instrunctions in <http://wiki.centos.org/HowTos/Amavisd> for installing Amavisd, Clamav and SpamAssassin on top of postfix/dovecot . Dovecot is working fine, but I want to deal with spam email. (I am using sendmail/dovecot with procmail and spamassassin on another server, but decided to go over to postfix on this server when I saw it is now the CentOS default.)

I'm almost completely ignorant about samba on Windows machines, In particular I know nothing about Windows permissions, if that is relevant here. I am running BackupPC on a CentOS-5.3 machine. It works perfectly for backing up Linux folders, but I have great difficulty extending it to Windows clients. To be precise, I have a share called "EA Games D" on a machine running Windows XP

I bought a very cheap server yesterday - an HP ProLiant micro server for 160 euro (280 euro with 120 cashback, for some reason). But I was surprised when I opened the box to find it didn't come with keyboard or mouse, and doesn't have the old keyboard/mouse sockets, but requires USB versions. Is that the norm nowadays? Is it possible to convert the old keyboard/mouse plugs? Also there is

I'm running CentOS-6 on an HP MicroServer (since this morning) and I'd like to open an non-standard port, for use on a laptop attached to the internet through the server. Do I have to explicitly add an iptables rule? If so, and I want to open (say) udp port 500 , what command should I give? I've always used shorewall in the past, and will probably do so now if the default firewall

Anyone got this working over a LAN under CentOS? The instructions claim it is easy to connect after pressing the WPS button on printer and router. Sadly, I don't see a WPS button on my Linksys WRT54GL router. When I press the WPS button on the printer the WiFi icon flashes, but I don't see any attempt to connect in /var/log/messages on my CentOS-5.5 server. Any advice or suggestions

I want to clone a small (80GB) disk on my CentOS server to a large (1.5TB) disk, as smart has been giving me warnings of unreadable sectors. Both disks are Western Digital, and WD has a WD version of Acronis True Image. I'm not sure whether to use this or Clonezilla. My worry with Acronis is that I want to keep the original disk, and I'm not sure from the documentation if True Image

I have a 1.5TB Western Digital hard disk (WD15EADS-00R6B0) on my CentOS-5.7 server, which has become incredibly slow for some operations, eg rsync, BackupPC archive, e2fsck, although it seems to work fine for ordinary file operations, and "smartctl -a /dev/sdb" does not report any errors. For example, running "e2fsck -p /dev/sdb5" on a 250GB partition on this disk took over 24

I don't understand Windows permissions under Samba. I am running an smb server under CentOS-5.4, and have a Windows XP Pro machine ("harriet") as a client. I have set up shares C and D on harriet corresponding to the 2 drives C: and D: on the machine, and I have asked that files should be shared. Now when I mount harriet:C I can see the top level folders, but cannot see Documents

I see that mail sent from a remote computer never leaves the computer, the last entry in /var/log/maillog being "Queued mail for delivery". 1. What is likely to cause this message? I know I registered with my remote mail server with a different name to my name on the computer. Is that likely to be the cause of my problem? And if so, what is the solution? Or is there any other likely

For some reason all the perl man pages cause yum errors like ------------------------------------- Transaction Check Error: file /usr/share/man/man1/c2ph.1.gz from install of perl-5.8.8-32.el5_5.2.x86_64 conflicts with file from package perl-5.8.8-32.el5_5.1.i386 ------------------------------------- 1. I don't really see how the man pages can cause conflicts; 2. More importantly, how
