Thanks, I can recommend Radiator by Open Systems Consultants [http://www.open.com.au/radiator/]. It is not a free piece of software but is well worth spending the $1,000 (AUD). It is very configurable and extensible [http://www.open.com.au/radiator/technical.html] (it is written in perl and can be extended using perl modules). You obviously also get the source when you buy it.

Re: zebra and bgp4
Hi, We use Zebra as a route collector on an alpha box running debian, we have it peering with a cisco 7206 and one of our Juniper M40's, we get a full routing table (104 thousand routes at them moment) on it in a couple of minutes and works with no problem. It's not used to route or pass any traffic though, purely a route collector. I'd say it would perform better than a 3600 as it seems accept routes as quick as any of our 72/7500 cisco routers, although again it doesn't carry any traffic.

Re: Apache load ballancing
I need to build a scalable webserver based on Apache. I'm not sure yet if the application requires persistent TCP connections. If so, it will require that after starting session all subsequent HTTP request in this session will come to the same machine in the cluster. This requires load ballancing in 7th layer, so LVS doesn't help much. 7th layer for sure? I'd imagine that would only need to land in the 4th Layer. 7th layer would be custom HTTP requests to test things like an application servers, CGI scripts, or PHP scripts (7th layer == application layer). The question is: are there any software level 7 ballancer available ? If not, which hardware box would you recommend ? I've not found any software suitable for the load balancing systems we run, which must support SSL, persistent connections (cookie, IP, etc.), and can handle a huge load. That said, we use a Foundry Networks ServerIronXL for load balancing, and it's an incredible box. Quite expensive new, but with all of the Dot-Bombs, you should be able to find one cheap on eBay or other auction houses. Best Regards- Eric Jennings [EMAIL PROTECTED]

Tool should preferably run on: Try using scotty (a package named scotty is in potato). This comes with a tool named tkined (using TK) which can map your network by scanning it. It makes heavy use of SNMP and brings some special modules for CISCO, Ascend and other router manufacturers, so you could use it also for management of your network.

Exim and SMS gateways
Hi all, I have got some problems with users on my server using email-to-SMS gateways. They put .procmailrc like this one: -- SENDMAIL=/usr/sbin/sendmail :0c * [EMAIL PROTECTED] | $HOME/email2sms | $SENDMAIL -t -- When the SMS gateway of someone's operator dies, the messages are bounced back and processed again by procmail. The error message is sent to SMS gateway, which bounces it again... So after some time I have thousands of messages in my spool. How can I prevent this behavior with Exim configuration options?
