Sendmail burst of "rejecting connections" - why?
by Steve Snyder 26 May '06

26 May '06

What's the reason for the burst of sendmail complaints below? My CentOS 4.3 server only handles internal mail for my small network. It doesn't handle Internet mail at all, so I guess I can't blame a crack attempt for this. IPTables rules should prevent external connections to everything except SSH's port 22. I've looked through the other logs hoping that some other activity would be seen at this time as well. Nothing. the surrounding entries in /var/log/maillog are perfectly reasonable. As far as I can tell this 14-minute burst of sendmail activity exists in isolation. Can anyone suggest a reason for these log entries? Thanks. ------------------------------------------------- May 25 07:09:24 server sendmail[2942]: rejecting connections on daemon MTA: load average: 24 May 25 07:09:39 server sendmail[2942]: rejecting connections on daemon MTA: load average: 25 May 25 07:09:54 server sendmail[2942]: rejecting connections on daemon MTA: load average: 26 May 25 07:10:09 server sendmail[2942]: rejecting connections on daemon MTA: load average: 29 May 25 07:10:24 server sendmail[2942]: rejecting connections on daemon MTA: load average: 31 May 25 07:10:39 server sendmail[2942]: rejecting connections on daemon MTA: load average: 32 May 25 07:10:54 server sendmail[2942]: rejecting connections on daemon MTA: load average: 33 May 25 07:11:24 server last message repeated 2 times May 25 07:11:39 server sendmail[2942]: rejecting connections on daemon MTA: load average: 34 May 25 07:12:24 server last message repeated 3 times May 25 07:12:39 server sendmail[2942]: rejecting connections on daemon MTA: load average: 34 May 25 07:12:54 server sendmail[2942]: rejecting connections on daemon MTA: load average: 33 May 25 07:13:09 server sendmail[2942]: rejecting connections on daemon MTA: load average: 32 May 25 07:13:24 server sendmail[2942]: rejecting connections on daemon MTA: load average: 31 May 25 07:13:54 server last message repeated 2 times May 25 07:14:09 server sendmail[2942]: rejecting connections on daemon MTA: load average: 30 May 25 07:14:54 server last message repeated 3 times May 25 07:15:25 server last message repeated 2 times May 25 07:15:40 server sendmail[2942]: rejecting connections on daemon MTA: load average: 29 May 25 07:15:55 server sendmail[2942]: rejecting connections on daemon MTA: load average: 29 May 25 07:16:10 server sendmail[2942]: rejecting connections on daemon MTA: load average: 28 May 25 07:16:25 server sendmail[2942]: rejecting connections on daemon MTA: load average: 27 May 25 07:16:40 server sendmail[2942]: rejecting connections on daemon MTA: load average: 26 May 25 07:16:55 server sendmail[2942]: rejecting connections on daemon MTA: load average: 25 May 25 07:17:10 server sendmail[2942]: accepting connections again for daemon MTA May 25 07:17:45 server sendmail[2942]: rejecting connections on daemon MTA: load average: 24 May 25 07:18:00 server sendmail[2942]: rejecting connections on daemon MTA: load average: 25 May 25 07:18:15 server sendmail[2942]: rejecting connections on daemon MTA: load average: 27 May 25 07:18:30 server sendmail[2942]: rejecting connections on daemon MTA: load average: 28 May 25 07:18:45 server sendmail[2942]: rejecting connections on daemon MTA: load average: 29 May 25 07:19:00 server sendmail[2942]: rejecting connections on daemon MTA: load average: 30 May 25 07:19:45 server last message repeated 3 times May 25 07:20:00 server sendmail[2942]: rejecting connections on daemon MTA: load average: 29 May 25 07:20:15 server sendmail[2942]: rejecting connections on daemon MTA: load average: 28 May 25 07:20:45 server last message repeated 2 times May 25 07:21:00 server sendmail[2942]: rejecting connections on daemon MTA: load average: 25 May 25 07:21:15 server sendmail[2942]: accepting connections again for daemon MTA

I realize currently libtiff is 3.8.2 but results drasticly >vary. Where do I get an rpm for libtiff 3.8? And once I install this later version, will a yum update put it back to 3.6.1-10? If so how do I exclude libtiff (I know, man yum).

Bandwidth shaper suggestion
by Matt Arnilo S. Baluyos (Mailing Lists) 25 May '06

25 May '06

Hello everyone, I'm looking for a bandwidth shaper that can limit downloads from certain IPs on a LAN. Any suggestions? I'm thinking of something that's easy to set up and configure. Even better if there's already a package that's on the CentOS repositories (or if not, maybe an RPM). Thanks and 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.

Load Balancing
by Mace Eliason 25 May '06

25 May '06

Hi, We are starting a new project, and are trying to decide the best way to proceed. We want to setup a LAMP configuration using Centos, something we have been doing in the past with great success. The question is load balancing. We antisipate the potential for the system to receive 500,000 requests/ day with in the next year. We want to plan for that extra load now as we start the project. What would you suggest for setups for multiple servers for redundancy and load balancing? I have setup MySQL replication and that works fine but what about the rest of the system. I know it is quite simple to setup with windows 2003 server. Would a cluster be the way to go? Ideally we would like 2-? severs setup that are all identical and sharing the load as need be, and if one fails users would notice nothing. I have also thought of just looking for a hosting company that offers load balancing servers and not worry about it but we like to have control. Thanks for any suggestions Mace

kbs-CentOS-Misc-Testing: thunderbird-1.5-2.el4.lsn looks OK under *light* use
by William L. Maltby 25 May '06

25 May '06

Installed today, light use in and out. All looks normal ATM. CentOS 4.3 current (but 1 kernel version to install as of today). AMD Athlon 2200XP using i686 versions. I'm not a heavy user of it. <OT> Waiting to see if I like it better than Evolution or not. Unfortunately, the more it looks like MS Windows product, the less attractive I find it. I'll probably end up blowing all this GUI stuff off and go back to pine or some-such. </OT> Thx for your efforts making the stuff the way you do. ... and smile, even if you can't chuckle a little! ;-) -- Bill

3ware 9550sx on CentOS 4.3 x64
by Fong Vang 25 May '06

25 May '06

3ware now provides driver disk for CentOS. A couple of months ago, I had to add support for the 3ware 9550sx. The driver disk provided for CentOS 4.1 work perfectly. I now need to add support for the 3ware 9550sx for CentOS 4.3 x64. Although the driver disk is available, it doesn't seem to work. Anaconda just can't find the 3w-9xxx module. This is the same seutp as CentOS 4.1 (which works) so I'm not sure how x64 is different. The driver disk contains the following files: modinfo modules.cgz modules.deppcitable rhdd Any help is appreciated.
