The following script works for us to send notifications to a mobile "server"
that can not process very long text messages. Unless you have perfect control
over who is allowed to use this script and what is being sent, it is VERY bad
security practice. Replace the bracketed setup stuff (inside <> ) with the
appropriate sources and destinations. "$argv" passess the raw data to be
transmitted. Depending on what's in the message, you may have to modify
the 3rd through 6th lines.YMMV.

Does anyone else have one of these on 24/7 running RHEL 5.4 or Centos 5.4 ?? That box mysteriously stops ( no crash data, it just stops) hours or days after boot, with or without X. Cntl-Alt-Delete reboots it without power cycling. The usual diagnostics (memtest and fsck) return no errors. Works great until it freezes. No evidence of kernel oops anywhere. If others report the same issues we will scrap the board. Otherwise I will continue to investigate what is happening, since it is no fun to pull the board out and replace with an atom processor and it is not critical. The hard disk in it came from an Athlon M board that died an untimely death this week. Service cpufreq reports "unavailable" so I am assuming that it is turned off. Could the cpu freqquency control be doing something without tellling us? We havea power monitor on it so I can discern if it dies with max cpu activity or not. Also I am leaving it run "top" without screensaver so I can see if a particular load or program is borking it. Am I missing something obvious here?

The upgrade to VMware Server 2.0.2 on 5.4 has not gone well for me. The XP shutdown command hangs.

I surrounded it with printk statements so I know that it is entering and exiting the rx setting. It acts like this variable is never being written to the chip register. Hmmm, I think I need to look at their code some more to make sure they ARE writing to the register. Despite the kernel messages, the chip does not enter the promiscuous mode.

[CentOS] RealTek 8168B (Rev 02) Issue
The 8168B (02) NIC works well except that it does not go into promiscuous mode despite advertising itself in that mode after being so directed with ifconfig. Unfortunately, the little box is destined to be an IDS monitor, so that function is essential. The board is an Intel Atom 330 run as x86_64, the nic is internal. We tried three drivers: the one in the 2.6.18-128.1.10.el5 kernel yields a high count of dropped packets (known problem), and the drivers from Realtek and El Repo. None solve the promiscuous problem (although they fix the funny dropped counter issue). Apparently the chip has no MII capability either. Anyone have any idea as how to make this chip do the promiscuous mode thing other than adding another nic card ? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It sounds like you did an update to clamav-0.95.
IF SO:
{
You must now do the configuration in /etc/clamav-milter.conf. Leave the
sysconfig as CLAMAV_FLAGS=" " . Read the man pages for both
clamd.conf and clamav-milter as they have both changed, although the conf
files are pretty well documented by themselves. Make sure the sockets in
the clamd.conf file is correctly referenced in the clamav-milter.conf file and
the milter socket is compatible with what you put in your sendmail.mc file.
}
[OT]:
{
The clamav folks completely rewrote the milter in 0.95 to require sendmail-
13 or higher. For anyone with an old (RHEL/Centos 3.9) distro, clamav-
milter-0.95 does not work with sendmail-12. I built and the installed the
sendmail-13 rpm from the RHEL4 (Centos4 should also work) src.rpm
before building and installing the clamav-0.95 rpm on one old machine. It is
now receiving and filtering mail happily (allthough oblivious to its scheduled
July date with the hardware recycler). Clamdtop even works with Centos 3.9.
Someone may want to put sendmail-13 in the Centos 3.9 centosplus
directory. A "clamav-0.95-for-sendmail-13" could also be put in the rpmforge
updates for EL3, although there are probably few customers for that item.

[CentOS] A Working 64 bit Browser Plugin - at Last!!
FYI: Upon installing 64 bit firefox on RHEL 5/Centos5/SAL5 , the first problem everyone seems to complain about is no working java plugin. A patched plugin from the Blackdown Project was available, but it was written against the vulnerable JRE 1.4.2. I too gave up on this until I discovered Red Hat's "iced tea" project. The latest incantation for Fedora Core 8 loaded well on a RHEL5 box using rpm's: java-1.7.0-icedtea-1.7.0.0-0.19.b21.snapshot.fc8.x86_64.rpm java-1.7.0-icedtea-plugin-1.7.0.0-0.19.b21.snapshot.fc8.x86_64.rpm tzdata-java-2007h-1.fc8.noarch.rpm Then do: alternatives --config java and select the new 1.7 JRE. Usually FC8 stuff doesn't install well on RHEL5/Centos5/SAL5 boxes. However, these worked like a charm SO FAR. [ Note, if you try these, uninstall all of your firefox extensions first because some of them have the potential to create the infamous XBL error message for non-root users]. After installation, navigate to Sun's java site and test using their applets to make sure you installed correctly. YMMV. May cause loss of some functionality elsewhere in the system.
