I am using scp to copy around 20 files and use ssh to change the permission of the files. Both scp and ssh fails once in a while. I ran with the -vv option and this is what is I see. source is solaris 8 and destination is solaris 10. It is not failing always. It fails once in a while. Could perform ssh command.
