host-notify-by-epager

[David Maynard]

Here are a couple of things to check.  Does your Nagios server have a valid
and matching forward and inverse DNS entries?  Does it use that name in it's
SMTP HELO greeting?  Is the mail server on the monitoring system otherwise
configured to "follow all of the rules" when it comes to SMTP?  The pager
(and SMS) email gateways have been adding anti-spam measures that can
"catch" monitoring systems that aren't normally mail servers.  The inverse
DNS requirement affects several of the gateways, but I don't remember
specifically about Metrocall.
 
I would try checking the mail logs on the monitoring system for clues on why
it isn't getting through.  If you know enough about the SMTP protocol,
telnetting to port 25 and entering the first few commands by hand will show
any responses if the SMTP logs aren't detailed enough.  (Someone should
write an SMTP debugger script to help identify common issues.)
 
This wouldn't be your problem, but for awhile the AT&T SMS gateway was
blocking any messages that had URLs.  The mail was accepted by their server,
but just dumped into a black hole.  As a workaround, we modified our notify
script to strip the http: using awk.  (Cingular has changed the gateway so I
don't know if they still do it.  I hope not, since I plan to replace my
phone with a Windows Mobile unit and would sure like to use URLs from
messages.)

I can send myself a test page from any email client via @page.metrocall.com
<http://page.metrocall.com/> .  So it is working....
 
What's weird is I can relay off localhost (nagios) to my gmail.com
<http://gmail.com/>  email account.
 
Why can't my nagios server send outside?  I looked at the firewall and I see
the source address coming into the inside interface, but it never leaves the
outside interface, so I need to punch a whole for port 25.  I'd rather not
do that and just relay off our outbound mail server.  Can anyone help me
with that? 

 
 
Thanks,
Justin

Not to ask a dumb question, but are you sure the @ page.metrocall.com
<http://page.metrocall.com/>  address is working?  We had to reconfig our
MetroCall pager notifications to use @ my2way.com <http://my2way.com/>
awhile back becuase they broke the Metrocall address.
 
FYI, I just received a notification that they are changing things again on
the weekend of August 11th.  They don't mention the metrocall address
working, but the my2way.com <http://my2way.com/>  is supposed to keep
working.  They are also adding one for the new USA Mobility moniker.

I have host-notify-by-epager working correctly with default commands in
misccommands.cfg.    host-notify-by-epager is not working, and looking in
system logs I see notification attempts to my pager at
XXXXXXXXXX at page.metrocall.com <mailto:XXXXXXXXXX at page.metrocall.com>  is
timed out with mailmx.archwireless.net  <http://mailmx.archwireless.net/> 

Jul 18 11:15:10 nagonet sendmail[11949]: k6IGDAil011947: to=<
<mailto:5128750223 at page.metrocall.com> 5128750223 at page.metrocall.com>,

dsn=4.0.0, stat=Deferred: Connection timed out with mailmx.archwireless.net
<http://mailmx.archwireless.net/> .

I can resolve via my nagios host: 

[root at nagonet network]# nslookup
> set type=mx
> page.metrocall.com  <http://page.metrocall.com/> 
Server:         192.168.200.18 <http://192.168.200.18/> 
Address:        192.168.200.18#53

Non-authoritative answer:
page.metrocall.com <http://page.metrocall.com/>       mail exchanger = 5
mailmx.archwireless.net <http://mailmx.archwireless.net/> .

Authoritative answers can be found from:
mailmx.archwireless.net <http://mailmx.archwireless.net/>  internet address
= 147.187.10.95 <http://147.187.10.95/> 

shouldn't this notification behave the same way as email.  the only
difference being that my email address I have in contacts.cfg is internal
and this epager address is external.  I'd like to use local host to send
from or I'm also willing to tell localhost about our outside mailserver. 

Anyone have a quick and easy solution for me :)  I'm it's something
simple......  I'm just missing it.
