Hi ,

Any idea why am I getting this error on my linux VM. I am trying create several VMs and have many ssh operations going on.

tcsetattr: Input/output error
tcsetattr: Input/output error

$ cat /etc/system-release
Red Hat Enterprise Linux Server release 6.8 (Santiago)

Thanks

the usual answer is: I assume you pay for your RedHat and you can ask the support.
You gave almost no information about your problem, therefore noone will be able to give you a solution. Probably you wanted to execute a process which require terminal (/dev/tty), but running it from an ssh session without terminal failed.

pan64,

Can you explain bit further...

are you saying I need to do ssh with "-n" options?

example

ssh -o StrictHostKeyChecking=no -o BatchMode=yes -q -ntt ........

I tried -ntt and it did not help... running out of ideas..

no, probably -t helps, but still you gave almost no info so I can only guess.
