You need to know, however, that a downstream LDM only queries the portmapper on the upstream host after first trying to connect to the upstream LDM using the well-known LDM port (#388). The fact that the pormapper query failed also indicates that the attempt on port 388 failed. The above is consistent with several possibilities, one of which is that Sirocco is not running an LDM. Another possibility is that Sirocco doesn't have an ALLOW line for Seistan in its LDM configuration file (etc/ldmd.conf). I note that I can, currently, ping Sirocco's LDM from here: $ ldmping -i0 sirocco.srcc.lsu.edu Jun 11 19:59:38 State Elapsed Port Remote_Host rpc_stat Jun 11 19:59:38 RESPONDING 0.074959 388 sirocco.srcc.lsu.edu > Thanks for the help Steve You're most welcome. > Bob > ---------------------------------------------------------------- > Robert Leche > System Administrator > Louisiana State University - Southern Regional Climate Center > 260 Howe-Russell Building > Baton Rouge, La. 70803 > address@hidden > 225 578 5023 > ---------------------------------------------------------------- Regards, Steve Emmerson
