Hi all,
We like many of you have obtained the BIND patch, to DU4.0D with patch kit
3, from Compaq. We have only installed it on a couple of machines and
encountered a problem immediately, when trying to use Veritas Netbackup. The
software stopped working giving messages like:
13:14:55 [11376] Couldn't get peer hostname
13:14:55 [11376] offset to GMT -3600
13:14:55 [11376] setup_sockopts complete
13:14:55 [11376] output socket port number = 996
13:14:55 [11376] peer_hostname: gethostbyaddr failed : NO_RECOVERY (3)
13:14:55 [11376] peer_hostname: gethostbyaddr failed to return peer host,
herrno = 3
We also noticed that when we tried to log in to a machine, which has the
BIND patch, from a machine with an underscore in its name, the entry in
/var/adm/wtmp does not resolve the calling machine's name, but uses the IP
address.
We have reported this to Compaq and they are sending it back to the folks
that wrote the BIND patch.
In the meantime, we have made our own fix, whereby our backups work again.
We have updated our DNS, so that machine names with underscores in become
aliases of machine names without them. We have not gone around and changed
the names on the various machines on the network, as the "bad" names appear
too many places.
I will guess that Veritas Netbackup software is not the only application
that might encounter this problem.
Best wishes
