Rob's questions

Perhaps you can help

I have quite a few mikrotik out in the field. They all connect to one 1 have in our data centre via l2pt or pptp.

Im using zabbix to monitor them, its discovery rule for the network interfaces work great. However it doesn't seem to work for the one at head office.

I get this message in the log:

SNMP agent item "ifDescr" on host "x.x.x.x" failed: first network error, wait for 15 seconds.

If i do a snmpwalk i get this result

snmpwalk -v 2c -c public x.x.x.x IF-MIB::ifDescr
IF-MIB::ifDescr.1 = STRING: 1 - Internet
IF-MIB::ifDescr.2 = STRING: 2 - DMZ
IF-MIB::ifDescr.39 = STRING: <l2tp-kepjbn>
IF-MIB::ifDescr.215 = STRING: <l2tp-km-1>
IF-MIB::ifDescr.299 = STRING: <l2tp-ct>
IF-MIB::ifDescr.378 = STRING: <pptp-ke>
IF-MIB::ifDescr.381 = STRING: <l2tp-in>

So it is getting result back from the router.

To setup the check for each interface will take a lifetime, i'd rather try correct the discovery rule.

Can anyone assist?

I wonder if anyone can help me.

The goal is to assign different users different ip address based on the AP they connect to. I cannot statically set this as users will travel and end up connecting via a different ap.

So i wanted to do a check to see if i can match the nas ip and then assign that user to a group, which in turn, the group will allocate the correct IP Pool.

I've done quite abit of research and its seems to be as simple as adding it to the radgroupcheck table. Like such:

 id | groupname |   attribute    |   value    | op 
----+-----------+----------------+------------+----
  1 | Group1    | Nas-IP-Address | x.x.x.x    | ==
  4 | Group1    | Pool-Name      | POOL1      | :=

However in the radius -X i do no even see it attempting to check the group.

It seems to check the radusergroup table, but there is nothing in there due to the fact i need to set the user group dynamically based on location.

Any help would be appreciated.

Thanks
