In short: Servers running CentOS 6 are accessible by hostname from Linux (LMDE & OpenSuse) clients, but not by Windows7 & CentOS clients.
Setup:
Firewall is pfSense-2.0.3, local servers are added in dns forwarder.
All servers & clients has the firewall as primary dns server.
Firewall name is cto.office.lan, ip 192.168.120.201
Example record in pfSense dns forwarder:
Code:
Host Domain IP
ctl-db0 lan 172.17.4.21
From LMDE:
Code:
ping ctl-db0
PING ctl-db0.lan (172.17.4.21) 56(84) bytes of data.
64 bytes from ctl-db0.lan (172.17.4.21): icmp_seq=1 ttl=64 time=0.165 ms
From Windows 7: (translated from Swedish)
Code:
ping ctl-db0
Could not find host ctl-db0.
BUT!
Code:
nslookup ctl-db0
Server: cto.office.lan
Address: 192.168.120.201
Namn: ctl-db0
Address: 172.17.4.21
Using FQDN ("ping ctl-db0.lan") it works fine.
We have several servers and it's the same for all of them so it can't be a caching issue.
All servers have static ip, all added to dns forwarder.
The server used above is a Xen guest on a separate subnet, routed via Xen host.
Other servers are on same subnet as firewalls LAN - 192.168.120.0/24 - it's the same issue with them.
I did empty both arp & dns-cache in Win7 just to make sure.
I also installed samba and started smb & nmb in CentOS-server.
