Timed out while zone transfer

[Johan Schröder]

Hello,

I set up a secondary nameserver, but the transfer of zone files from the 
primary nameserver doesn't work.

When I enter

# rndc retransfer domain.com

I get this error (in the log file)

named[22513]: transfer of 'domain.com/IN' from xxx.xxx.xxx.xxx#53: 
failed to connect: timed out

I checked the primary, the secondary nameserver and also the firewall, 
but I do not understand why the zone transfer is not successfull. Any idea?

Regards, J. Schroeder
