Re: TCP Tunnable Parameters
Here's another source, reffering to kernel 2.4 :

Just ask here if some terms seem unfamiliar to you.
Have a nice week end.

Re: TCP Tunnable Parameters
kindly look in to the problem in this perpective. why are we not getting SYN_ACK back from the destination host to your source host ?.
But please don't search for a solution to avoid SYN_SENT state in your source host.
Any Silent Drop rule in netscreen firewall for that destination host and for that particular destination TCP port ?.
Have you analysed the log files of netscreen firewall with log filtering for the packets from your source host ?
Have you run a packet sniffer in your destination host behind the firewall and
researched whether your destination actually receives SYN from your source host ?
What is the round trip time between your source host and destination server ? ( use ping and traceroute to find RTT overall and hop-wise ) ?
Do you have this problem for all the destination hosts hosted behind firewall in the remote network or only for this particular destinaton host and service ?
