Error during DTLSPAWN batch: Received message too long

Post by LeonBylsma »

Hello again. When running a SFTP in batch mode from Zos, I get this error to one of our servers and yet SFTP to some other servers still runs ok and I'm not sure if the problem is on Zos or on the server that I send to .... see error at he bottom of the pasted job output ( [00405] Received message too long 1416128883)

Run the client to the failing server again with debug3 on (add option "-vvv" to your sftp args) and send the joblog to info@dovetail.

Can you use this server from another sftp client? I would guess that you will get the same error.

You are probably having this problem:

http://www.snailbook.com/faq/sftp-corruption.auto.html

This means that the target SSHD server's user has a profile script that is printing out some welcome messages. This is incompatible with using SSHD and sftp-server. If this is your problem, one solution is to check the terminal type before writing things out in your shell profile:

if [ ${TERM} != "dumb" ]; then
echo Welcome to our fine system
fi

Thank you for the suggestion. I was still trying to get the server administrator to set the traces for me on his side and we had different errors until now (so I was not ignoring your previous post though :-D )

I will let you know the results for sure ..
