Hi all,
Not sure why this is, but it has been bugging me for a long time...
All of our Windows XP client hostnames show up properly, e.g.:
Sep 13 10:27:39 mailhost postfix-587/smtpd[16373]: 4371BA7D5ED:
client=validhost1.example.com[192.168.1.54], sasl_method=PLAIN,
sasl_username=validu...@example.com
nslookup shows:
mailhost : Thu Sep 13, 10:28:07 : ~
# nslookup 192.168.1.54
Server: 192.168.1.160
Address: 192.168.1.160#53
54.1.168.192.in-addr.arpa name = validhost1.example.com.
and
mailhost : Thu Sep 13, 10:28:35 : ~
# host 192.168.1.54
54.1.168.192.in-addr.arpa domain name pointer validhost1.example.com.
We recently started rolling out Win7 boxes (a year or so ago, but doing
it slowly), and for some reason, Windows 7 clients don't show the
hostname, only 'unknown':
Sep 13 10:46:09 mailhost postfix-587/smtpd[16228]: C2B50A7D5B0:
client=unknown[192.168.2.33], sasl_method=PLAIN,
sasl_username=validu...@example.com
nslookup shows:
mailhost : Thu Sep 13, 10:47:54 : ~
# nslookup 192.168.2.33
Server: 192.168.1.160
Address: 192.168.1.160#53
33.2.168.192.in-addr.arpa name = validhost2.example.com.
and
mailhost : Thu Sep 13, 10:48:05 : ~
# host 192.168.2.33
33.2.168.192.in-addr.arpa domain name pointer validhost2.example.com.
Yes these two are on different subnets, but it is the same for Win7
clients that are on the same subnet.
Anyone know why this is and/or how to fix it? I don't guess it is a real
problem, but I don't like 'unknowns'... ;)
Thanks for any suggestions...
