msmtp certificate, tls_trust_file, verified

Posted 11-25-2011 at 08:50 AM by ted_chou12

Hi, I recently installed msmtp, I tried a lot of certificates, the one that I found to work was in /etc/ssl/certs/ca-certificates.crt
If you by any chance don't have it in that directory, it could be partial install or something. (It should come with the package).
Email me if you need it.
Thanks,
Ted

Iptables rule traversal: bandwidth at >= 10K of IP addresses

Anyone who is interested in iptables performance will find Harris, Melara, Smith and Nico's "Performance analysis of the Linux firewall in a host" (2002) and Kadlecsik and Pásztor's "Netfilter Performance Testing" (2005). But what actually is the effect of a large rule set on performance?

The attached PDF I created is not an an exhaustive study of Netfilter performance but shows you Jperf data and pictures (joy!) for plain rule sets, ipset (iphash) and the iptables...

Migration from Solaris 10 to Red Hat Enterprise Linux

Posted 11-23-2011 at 10:15 PM by bits45

We've been using Solaris 10 on Sparc and x86 for years. With the recent Oracle takeover and the lack of OSS movement (updates) from Sun (too little, too late), we've been moving all of our Apache and MySQL servers to RHEL 5.7. In most cases we've stayed on the same exact Egenera Nehalem pBlades and used the same SAN storage. So all the hardware is exactly the same. The speed increase comparison between Solaris 10 and RHEL has been nothing short of amazing. Seems like everything goes faster...

openSUSE 12.1 GNOME Clean-Up

Posted 11-22-2011 at 06:22 PM by wagscat123

Even though there technically is no connection between the releases in the 11.x series, I'm still very happy to see 12.x out now. (11.0-11.4 all had been under Novell, used KDE4 by default and used GNOME 2)

Something I've learned about openSUSE 12.1:

1. To imitate GNOME 3 as much as possible
Unlike previous changes to the GNOME default look, it is impossible to bring GNOME 100% back to the way to was before. However, you can make it look much more similar.

Slowly getting it...

Posted 11-22-2011 at 04:12 AM by m3rl1n

Since my last blog entry - in which I mentioned that I would start learning about Distributed Technologies, I have been going through many AHA! moments that Sigmund Freud so nicely described. In my quest for getting savvy on Distributed Object Programming I found that CORBA is the only way to go. It is well known as a complex mess of incomprehensible matter in many communities. I shared that vision since last week, now I think it is quite doable.

The secret to learning CORBA is to...
