Re: Getting LDM on plane to receive via UCAR RAS and PPP

Janet,

I did the following:

    1.  Commented-out the "exec pqbinstats" entry in the LDM
        configuration-file, $HOME/etc/ldmd.conf, because it uses a lot
        of the CPU for no good purpose.

    2.  Commented-out the "exec pqact" entry in the LDM
        configuration-file, $HOME/etc/ldmd.conf, because you don't seem
        to be doing anything with the data (the pqact(1)
        configuration-file, $HOME/etc/pqact.conf, appears to be the
        example one that comes with the distribution).

    3.  Added a crontab(1) entry to rotate the LDM logfile at midnight,
        local time, every day.

    4.  Added the entry

            allow   ANY     ^[a-z].*\.atd\.ucar\.edu$

        to the LDM configuration-file, $HOME/etc/ldmd.conf.  This might
        be too general for you and you might want to restrict it to, for
        example

            allow   ANY     ^linus\.atd\.ucar\.edu$

        An ALLOW entry like this has never been necessary -- that I can
        recall.  I don't know why your situation is different.

    5.  Restarted the LDM.  The command

            ldmping

        now works, as do the various rpcinfo(1) commands such as

            rpcinfo -t linus 300029 6

You should

    As the superuser (i.e., root):

        1.  Change the ownership of the hupsyslog(1) utility,
            $HOME/bin/hupsyslog, to "root" and then enable the setuid
            bit.  This will enable proper rotation of the LDM logfiles.

        2.  Add the line

                search atd.ucar.edu

            to the top of the file /etc/resolv.conf.  It used to have
            this.  Why was it removed?)

    As the LDM user on another system, try to ldmping(1) the LDM on
    Linus (I couldn't log onto Cirque).

Regards,
Steve Emmerson

Steve,

The rcp.ldmd was not the right permissions, owner.  I fixed that and now 
rcpinfo shows port 388 for the ldm port on linus.  (That's what happens 
when you use someone else's install of ldm instead of reinstalling it 
yourself.)

rpcinfo -t linus 300029 6 from linus still does not work correctly.  I've check
ed the allow lines in the conf file and restarted ldm and still the same behavi
or.

The ldmping from an outside host now gives a different error:
ldmping linus.atd.ucar.edu
Jun 29 19:34:14      State    Elapsed Port   Remote_Host           rpc_stat
Jun 29 19:34:14  ADDRESSED   0.014074    0   linus.atd.ucar.edu  RPC: 
Unable to receive; errno = Connection reset by peer

which seems to be related to the rpcinfo command not working on linus.

Sure, you are welcome to log onto linus and cirque.  I think the main 
problem now is just linus and not cirque.  cirque is currently connected 
to the internal network as cirque.atd.ucar.edu.

Thanks,
Janet
