spam control
by Jerry Geis 31 Oct '06

31 Oct '06

Gents, I have added the following to /etc/mail/sendmail.mc and rebuilt it trying to control spam. I still get about 25 spam messages a day. Is there something else that can help control spam?

Spamassassin/Sendmail issues
by Tom Elsesser 31 Oct '06

31 Oct '06

I am running a server with Centos 4.4, using a combo of sendmail-clamav-spamassassin for mail, which has been working quite well up until last night. Around 3:00am, all mail going to all users was being rejected by spamassassin. My ~/mail/.procmailrc is as follows: ======================== MAILDIR=$HOME/mail # :0 H * ^X-Spam-Status:.*Yes { EXITCODE=67 :0: /dev/null } ========================= Checking yum logs, nothing that would affect SA or sendmail was updated, so I have no idea why everything would suddenly go bananas. Clamav was updated, but that was at 5:00am, and the mails were getting bounced back starting at 3:00. I am attaching 2 maillog snips showing mail from the centos list, with one going thru as expected and the other getting bounced back per my .procmailrc file. Any help appreciated. -- TomE.

The elephant in the room: Oracle
by Tarun Reddy 31 Oct '06

31 Oct '06

So what does everyone else think of Oracle's announcement? http:// developers.slashdot.org/article.pl?sid=06/10/25/2316221 I kind of think that they are going to be hurting RedHat (a valuable partner if you believe their deployment numbers). Oh silly, silly Larry. I guess the only hope that we have is that it actually increases mind share of RHEL and hence broader support for it (and subsequently CentOS). Tarun

Installing on Hardware RAID - Adaptec 7890/7860
by Matt Arnilo S. Baluyos (Mailing Lists) 31 Oct '06

31 Oct '06

Hello everyone, I'm trying to install the CentOS 4.4 Server CD on old hardware. The hardware is a Dell PowerEdge 2300 with Adaptec 7890 and 7860 controllers. It's the first time I've done a Linux install with hardware RAID. However, I'm having trouble getting CentOS (as well as Fedora Core 6) to detect the SCSI hard drives. When it comes to the part where you choose where to install Linux, it just doesn't detect the hard drives. It shows on the hardware configuration when the system boots up and when I try to install Windows 2003 Server, the drives are detected - so I don't think it's a hardware issue. Now, the question is - do I have to initialize something on the installation process? What do I do so that I can install CentOS with this specific configuration. Best regards, Matt -- Stand before it and there is no beginning. Follow it and there is no end. Stay with the ancient Tao, Move with the present.

Dual Opteron or Dual Xeon?
by Mike Kercher 31 Oct '06

31 Oct '06

I am about to lease another server to be a backup web/mail server with a replicated mysql database. The current live server is a dual Xeon 2.8Ghz. Would I do better to get another Xeon server or an Opteron based server? My concerns are compatibility of the database and the SSL certificate currently running on the Xeon machine. Are these concerns unfounded? TIA Mike

Question about printer
by Ivan Arteaga 30 Oct '06

30 Oct '06

Hello List, I have centos 4.3 and a printer Xerox4517 attached to it via parallel port. The problem I have is after some while of inactivity I cannot print, and when I check in the control center (KDE) I see the printer status is stopped (accepting jobs). I just have to start the printer and I can get it back to normal. It is possible to configure some kind of keep alive or something like that in order the printer doesn't go to the stopped state? I will appreciate your comments, --Ivan.

DomainKey and mailing list
by Aleksandar Milivojevic 30 Oct '06

30 Oct '06

Hm, my previous post on subject seem to have fallen in /dev/null (can't find it even in list archives, strange). Anyhow. While on the subject of spam control. I was playing lately with Domain Key (and also newer Domain Key Identified Mail) systems. It's currently primarly used by Yahoo and Google Mail (gmail). For example, all emails from gmail.com on this list have DomainKey-Signature header. Also, all of those emails fail the verification. It is most likely due to the mailing list mangling the Subject line (addtion of [CentOS] tag) and body of the message (addtion of footer). Currently, Google uses "in testing flag" in the DNS record (as can be seen from output of "dig beta._domainkey.gmail.com txt"), so none of those emails should be rejected by anti-spam software. However, if they change the flags to instruct anti-spam software to reject emails with invalid signatures, the emails from this (and many other) mailing lists will start bouncing big time. I guess if these systems become widespread in the future, either the mailing list will need to be updated (so that it regenerates signatures with its own key, as defined in proposed standards) or mangling of subject line and the body will have to be abandoned... Maybe it's a good time to start preparing for the possible future. -- NOTICE: If you are not intended recipient, you are hereby notified that by reading this message you agreed not to disturb frogs during mating season.

Terminal settings question.
by David Mackintosh 30 Oct '06

30 Oct '06

Hiya folks, Maybe someone can help me with this question. I'm a long time mutt user. However in recent years, I have been a member of an increasing number of mail lists. And an increasing number of mail list users are starting to use special characters in their emails that my terminal is not understanding correctly. When it doesn't understand the character correctly, it starts to interfere with the repaints when I scroll around through messages or through the indexes. As an example, I believe it was this list where there was recently a discussion regarding Core Duo which included a fancy symbol for (tm) in the subject line. This thread was the straw that broke the camel's back so to speak and I'm now an unhappy Thunderbird user as opposed to a happy mutt user. So. Clearly I have something set incorrectly so that Mutt (and/or the terminal I am using) do not understand the special characters. Can anyone point me in the right direction to find the answer as to how to fix this so that I can ditch Thunderbird and go back to Mutt? Thanks for your time. -- -- /\oo/\ / /()\ \ David Mackintosh | dave(a)xdroop.com

Booting kernel for installation CD
by termeau sebastien 30 Oct '06

Hello, I want to install CentOS 4.4 on a Compaq Proliant DL 360. The installation fails just after booting on the first CD. Linux tries to autodetect hardware and fails with the CDROM. Here is the error message: ########################## hdc: CD-224E, ATAPI CD/DVD-ROM drive Using cfq io scheduler ide1 at 0x170-0x177,0x376 on irq 15 ide-cd: cmd 0x5a timed out hdc: lost interrupt ide-cd: cmd 0x5a timed out hdc: lost interrupt CDROM 24x .... ide-cd: cmd 0x25 timed out ########################## I can install a RHEL4 ES on the same server whitout problem. I noticed that CentOS and RHEL use 2 different kernels to boot the 1st CD (in isolinux folder). So I tried to replace the CentOS kernel with the one I found on RHEL CD. And it works, the kernel boots, but my CentOS CD is not recognize anymore as a CentOS CD. Why CentOS didn't recognize my CDROM? What should I modify in order to install CentOS using the RHEL kernel?
