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!
