Hola Claudia,

You are most welcome!

I see that I can 'ping' your machine:

% ping unidata.at.fcen.uba.ar
unidata.at.fcen.uba.ar is alive

but I am not able to SSH to it:

% ssh address@hidden
ssh: connect to host unidata.at.fcen.uba.ar port 22: Connection refused

or 'ldmping' it:

$ ldmping unidata.at.fcen.uba.ar
Mar 03 21:59:53 INFO:      State    Elapsed Port   Remote_Host           
rpc_stat
Mar 03 22:00:03 ERROR: SVC_UNAVAIL  10.008258    0   unidata.at.fcen.uba.ar  
h_clnt_create(unidata.at.fcen.uba.ar): Timed out while creating connection

Given this, I am guessing that someone at UBA has installed a firewall
that is blocking not only SSH (port 22) but also the port used by the
LDM for data transfer (port 388).  You should contact your department
network administrator and possibly a UBA administrator to find out if
they have installed firewall rules that are now blocking port 388 (and
port 22) traffic.

Ciao,

Tom
