Hi Ron, If you need a newer version of nc, feel free to compile and install it within your home directory. Alternatively in the next few months I'll be upgrading the logins to RHEL7 which should include a newer version of netcat. Ben

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
Thanks! Ron
