Means you'd better use IP instead of host name, or you have to ask
your DNS administrator to setup reverse DNS (PTR record) for those
IPs, which may involve your upstream ISP, or even more complicated
than that ...<br>

How about DNS revert delegation? Try "host <IP>" to
see if it can be mapped back to "hostname1" then there
should be something wrong, otherwise you have DNS problem.<br>

P.S. I guessed because I believe whenever a connection
comes in, the server does not know anything other than IP
and port.<br>

<div>I tried to set auth.allow using
hostnames (not IPs) of clients <br>
such as <br>
</div>
gluster volume set VOLUME auth.allow
hostname1,hostname2,hostname3<br>
<br>
But the clients could not mount the
volume<br>
</div>
If I use IPs, it defintely works.<br>
</div>
But for my clients use DHCP, so I don't
think using IPs is a good idea for they
could be changed but hostnames of them
wouldn't. <br>
