Last night, I saw a message that bind could not update a journal file, because it couldn't create it. So I manually created a "mike-leone.com.jnl" file, owner bind. Then, after making the changes you recommend here (thanks for that, BTW), I see this, when starting bind: Feb 21 12:11:26 mail named[4113]: zone mike-leone.com/IN: journal rollforward failed: no more Feb 21 12:13:07 mail named[4113]: client 127.0.0.1#4338: updating zone '100.168.192.in-addr.arpa/IN': deleting an rrset Feb 21 12:13:07 mail named[4113]: client 127.0.0.1#4338: updating zone '100.168.192.in-addr.arpa/IN': adding an RR Feb 21 12:13:07 mail named[4113]: journal file /etc/bind/192.168.100.ptrs.jnl does not exist, creating it Feb 21 12:13:07 mail named[4113]: /etc/bind/192.168.100.ptrs.jnl: create: permission denied Feb 21 12:13:07 mail named[4113]: client 127.0.0.1#4338: updating zone '100.168.192.in-addr.arpa/IN': error: journal open failed: unexpected error Feb 21 12:13:07 mail dhcpd: unable to add reverse map from 73.100.168.192.in-addr.arpa. to laptop-mjl.mike-leone.com: timed out So I guess I need to make a journal file for the reverse ptrs, the same as the journal file I created for the forward. I guess what I really need is to make the /etc/bind directory writable by the user bind. How best to do that? > ---------------------------------------------------- > > Alternately, if dhcpd and bind are on seperate machines, They're not. Attachment:
