We are running zos 2.2 with cozbatch 5.5.0 to initiate ssh sftp client session to a linux server over the internet. We get the error 'Received disconnect from xxx.0.xx.xxx: 11: Sending of channel data timed out' at peak times on the server through the day, this is not our server. I have run a tcp packet trace and sent it off to IBM, I have that response below but they are saying there are retransmissions on the connection that the client is not handling. The server folks tell me they have no other clients that have problems.
Here is the catch, it only happens with the ssh client. I can pull over 200 files using filezilla on my desktop and same for my RH linux guest on zvm. I'm at a loss as to where to go with this issue, wonder if anyone else has ever had this issue or might have suggestions to try? Thanks Matt Current job settings -oConnectTimeout=600" -oServerAliveInterval=600" -oTCPKeepAlive=yes" -oServerAliveCountMax=5" IBM Response to trace info - There is a significant level of packet loss between these systems, which is forcing retransmission of packets. Your local network support team will need to investigate that. - The server system is very sluggish in performing the retransmissions. There are long periods where it is not sending the missing data, which is likely why the server's administrators are saying that the client is not responding (it can't respond at the application layer until the missing data arrives). One example I examined, it was 9 seconds before the retransmission occurred, for another (closer to the end) it was 79 seconds. That is way beyond normal! That system's administrators need to contact the TCP software's vendor to get this corrected.
