Hi all, I am using Linux 6.4. When I am trying to mount from the client from a program via the tcp socket the server closes the tcp socket after reaching the state TIME_WAIT. I have disabled the iptables rules. But still it doesnot help. I think I am having similar problem as mentioned in below thread. http://www.spinics.net/lists/linux-nfs/msg13036.html I have a couple of questions: 1. How can i recover from this state? [root@hostarena~]# netstat -tp Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 hostarena.yyy.org:49423 hostblob.yyy.org:33973 TIME_WAIT - [root@hostarena ~] the /var/log/messages after enabling the rpc_debug didnot show anything meaningful. NFS Server is listening for mount requests at port 49423. I am suspecting time_wait state is due to the fact that source-port is > 1024(i.e 33973) for root. 2. Is there a way i can configure the linux nfs server to accept from non- reserved port > 1024? 3. Is there a way i can tell the client socket to choose the source ports < 1024 for mount without changing the /proc/sys/net/ipv4/ip_local_port_range at the client? I appreciate somebody can throw some light to fix the issue? Note: All the RPC services are running at the NFS server(confirmed by rpcinfo -p) Regards Pradeep
