If TCP connections randomly hang, try disabling this, # and bug the vendor of the losing equipment. # tcp_extensions=NO -----end of snip------- or do a: sysctl -w net.inet.tcp.rfc1323=0 sysctl -w net.inet.tcp.rfc1644=0 as root, and try again. I tried bugging my ISP about the stuff, but he said something about 'Linux works just fine with it', so I'll just live without the TCP extensions (whatever they do exactly anyway???) -Troy
