[Xymon] rrd logs and graphs

[Vernon Everett]

Hi Jeremy

I think you got that one nailed.
I added
  send ""
  expect ""
as you requested, and it cores again.
This time on the next entry, which is telnets
[telnets]
   options ssl,banner,telnet
   port 992
Again, no send and expect.
Updated telnets, and it crapped out at ldap.
[ldap]
   port 389

[ldaps]
   options ssl
   port 636

[rsync]
   expect "@RSYNCD"
   options banner
   port 873
About now, I am getting a little nervous adding send and expect, because
unlike telnet and telnets, we are doing ldap and ldaps testing.

Any suggestions?
I think we have some debug code update recommendations for JC though. :-)
A good win, but still doesn't solve my original problem. :-(

Regards
Vernon
