Hi all, I'd like to configure a multi-hop ssh connection to some of the JLSE machines, but I"m having issues. On my local machine, I put the following in my ~/.ssh/config Host jlseLogin

Hostname login.jlse.anl.gov User rahaman Host maud ProxyCommand ssh -q jlseLogin nc -q0 %h 22 User rahaman

But the version of netcat on the JLSE login node doesn't recognize many options I'm used to, and I can't get it to establish a connection. Similar commands work fine on the MCS login node, where the version of netcat is different. For example, this works fine: Host mcsLogin

Hostname login.mcs.anl.gov User rahaman Host thrash ProxyCommand ssh -q mcsLogin nc -q0 %h 22 User rahaman
