[JSch-users] End of IO Stream when connecting to few servers

[Preetham Kajekar]

Hi,
I am trying to connect to a SloarWinds SFTP server using JSCH. It fails
with the below error. I have noticed this happens with a bunch of other
SFTP servers as well, but works fine on an OpenSSH server. I am guessing
this is some kind of config issue and any pointers would help.

Thanks,
