When the receiving party explicitly denies accepting a packet,that means that there is no connection anymore. There is nothing more you can do but reconnect. > you know what "reasonable defaults" means ? some minutes ? Examples: $ cat /proc/sys/net/ipv4/tcp_keepalive_time 7200 $ cat /proc/sys/net/ipv4/tcp_retries1 3 $ cat /proc/sys/net/ipv4/tcp_retries2 15 $ cat /proc/sys/net/ipv4/tcp_synack_retries 5 $ cat /proc/sys/net/ipv4/tcp_syn_retries 5 There are many more. Tuning them requires good knowledge of TCP internals. -- /\_./o__ Tomasz Sterna (/^/(_^^' http://www.xiaoka.com/ ._.(_.)_ im:[EMAIL PROTECTED]
