Hello guys,
I have 5 machines in a home network, all running F9, with
named/bind providing local DNS.
A couple of weeks ago a problem appeared: ssh hangs for internal
connections. No doubt
I had misconfigured the thing years ago, as bind mystifies me, but an
update must have triggered it.
The problem is that reverse lookups hang forever; here is the end of
"ssh -vvv XXX"
debug1: Next authentication method: gssapi-with-mic
debug3: Trying to reverse map address 168.254.0.251.
Note the 'dot' at the end.
If I try nslookup 168.254.0.251 it works fine, but 168.254.0.251. does not.
Just curious.... Why do you want to use "168.254.0.251." If you were to
use a trailing . on IP addresses outside of your maps you'd find they
wouldn't get resolved either.
$ host 64.236.24.12
12.24.236.64.in-addr.arpa domain name pointer www3.cnn.com.
$ host 64.236.24.12.
Host 64.236.24.12 not found: 3(NXDOMAIN)
$ host 64.236.24.12
12.24.236.64.in-addr.arpa domain name pointer www3.cnn.com.
So, just don't know what value adding the trailing . has for you or what you
are expecting.
Can anyone suggest what I am doing wrong? Here is named.conf, in case
that helps.
Thank you!
