Re: strqsh rexec command question

hi Tim,

The error "host cannot be found" *usually* means that a DNS lookup 
failed.  (And yes, I know you're using an IP address.  But AFIAK, the 
rexec() protocol doesn't normally support them, so I bet it's looking up 
the host name from the address in order to use the host name instead!)

What happens if you do an nslookup on the IP address of those that do 
work vs. those that do not?

   NSLOOKUP HOSTNAME('xxx.xxx.xxx.xxx')

Do you get the same results with those that work vs. those that do not?

What happens if you add the hosts do your host table?  (NOTE: I do not 
recommend this as a solution -- only as a test for diagnostic purposes.)

  ADDTCPHTE INTNETADR(XXX.XXX.XXX.XXX) HOSTNAME((XXX.EXAMPLE.COM))

Then try the rexec again.

If that solves the problem, it means you have a DNS issue.  In that 
case, I'd get the DNS fixed, and remove the host table entries, and it 
should then work without them.  (CFGTCP option 10 is an easy way to 
find/remove them.)

I doubt very highly that this is related to whether the rexec daemon is 
running.  If rexec wasn't running, you'd get "A remote host refused an 
attempted connect operation."

Let us know what you find...
