I don't really understand what you're doing here are you doing here, are you starting 160 ping commands or is it just one command and the fun starts after it send out 160 packets? Well, if you're starting 160 ping commands in paralell, removing ping won't help you, there are other commands which can do that to (like make -j on the kernel tree or some tiny fork bomb, you can write one in every shell). In this case you want to look into pam-limits, as others in this thread suggested. If just one ping command is enough to do that, than you either found a bug somewhere in the software or you have a problem with your hardware. I had the problem once that tcp-connections got stuck after some kbytes on an old 486 on a 10MBit network, the problem was that the default WSS or MSS or something like that (I don't remeber exactly) was raised in newer kernel and my machine was simply to slow to handle it. I dont't believe though that this is exactly your problem. Regards, Jö. -- Of all the things I've lost, I miss my mind the most.
