I don't know if you are trying to reach the same destination or each stream goes to a different destination. If it is to a different destination, you could think about setting static routes to each destination using the appropriate interface. When TG was written I don't remember being able to bind a particular socket to an outgoing interface. I haven't looked at sockets in quite awhile so I don't know if functionality like that exists now in case you actually want to go the same destination. Oh yes, if the kernel supports ToS/QoS/DiffServ routing, you might be able to play some games there. Each stream would have a different DiffServ/Tos/Qos value that maps to the "right" interface based on what routing gave you. Unfortunately, I haven't had the time to keep up what is really offered here. hope this helps, barbara --- "D.

Message-ID: <053A52EBA3EFA749AE9F25D70D1F364C254B23@uk-e02.uk.mis.vianetworks.com> Hello all, I am using TG on three servers, two FreeBSD and one Linux server. TG is configure to send and receive a number of TCP protocols between the three servers to simulate a real network. The Linux server is doing the most work running 8 TCP sinks and sending 16 TCP sources. The sources are set to run every twelve hours using cron while the sinks run all the time. The problem is after a couple of days the Linux server runs out of memory and freezes. It has to be rebooted to make the server useable again. The TG program has been moved from one Linux server to another so I do not think the problem is hardware. I started using the Linux binaries but then I compiled the source code to see if that solved the problem, but no. Below is output from syslog. I have had no problems on the FreeBSD servers. Can you please help? What can I try? thanks, Marcel Jan 13 22:33:13 war-test-svr kernel: Out of Memory: Killed process 2233 (tg).

There is a command to make multiple log files if you are gathering lots of data (see the user manual). barbara --- "Rafter, Marcel" wrote: > > Hello all, > I am using TG on three servers, two FreeBSD and one > Linux server.
