Openssh is not working while putty is able to create tunnel with the ssh server
ssh -i /root/.ssh/jrising.ppk jrising@firstname.lastname@example.org -p 7879
I have tried to create an ssh tunnel. Putty creates it well while openssh sucks.
Need urgent help
Are you trying to use the same key file that you use for PuTTY? If so, then that is your problem. You need to convert it to the format that OpenSSH uses (the key generator for PuTTY can do this).
