Hi all,
I hope I am on the right list for the problem I am experiencing.
We have two subnets 192.168.196. 192.168.222.
Our main LDAP servers run in 192.168.196. and are load-balanced by round-robin DNS. The 192.168.196. network is exhausted, so we added a new LDAP slave to 192.168.222. and added the IP address to the round-robin pool. But it seems that it is only used by other servers in the 192.168.222 network and not by servers in the 192.168.196. network
This setup has now been running for 6 days, with nscd.conf: enable-cache hosts yes positive-time-to-live hosts 3600 negative-time-to-live hosts 20 suggested-size hosts 211 check-files hosts yes persistent hosts yes shared hosts yes max-db-size hosts 33554432
and nslcd.conf: uid nslcd gid ldap uri ldap://ldap.div.ourdomain.nl/ base dc=div,dc=ourdomain,dc=nl ssl no tls_cacertdir /etc/openldap/cacerts
The LDAP server in the 192.168.222 range serves only 33 connections all from the 192.168.222 range, and the 2 hosts in the 192.168.196 range serve 599 and 706 connections. The last 2 servers do serve the 143.121.222. network also. So might there be some caching issue?
$ getent ahost ldap.div.ourdomain.nl 192.168.196.190 STREAM ldap.div.ourdomain.nl 192.168.196.190 DGRAM 192.168.196.190 RAW 192.168.196.151 STREAM 192.168.196.151 DGRAM 192.168.196.151 RAW 192.168.222.179 STREAM 192.168.222.179 DGRAM 192.168.222.179 RAW
Is this the right list for this question? And if so can someone help me understand what is going on?
With kind regards,
Dennis Leeuw
