What have you already done about this line??

Hi,

Which directory it is asking about?? My named.cfg file is in /var/named/chroot/etc and zone files are in /var/named/chroot/var/named

I have given the permission as chown -Rv named:named /var/named/

But still it is not working.

can you show us the output os "ls -lR /var/named"

also run "named -u named -D -t /var/named/chroot -d3 -f"

for a heap more debug output.

Hi eric,

Now I am in /var/named/chroot and i run the command chmod g+w named of /var/named/chroot/var and the error message is not showing in logs. But still the service is showing failed when i restart the service.

These are the files you want to have a view:

-rw-r--r-- 1 named named 4147 Jan 28 15:55 named.run

right, so run with debugging on.

Hi eric,

I have run the command given by you, that is

named -u named -D -t /var/named/chroot -d3 -f

and the output is

process 8780: Re-entrant call to dbus_connection_set_watch_functions is not allowed
Segmentation fault (core dumped)

Hi,

I still cant understand why the DNS server giving this error. kindly help me plz.

hmm, that's a weird error. that was just the last line of it right? A little more context around it might help.

is bind and dbus fully updated on the box?

Hi eric,

This is the error I am getting again

process 8902: arguments to dbus_connection_unref() were incorrect, assertion "connection->generation == _dbus_current_generation" failed in file dbus-connection.c line 2615.
This is normally a bug in some application using the D-Bus library.
Segmentation fault (core dumped)

Hi,

again shows a different error

are you sure named isn't already running?

Hi eric,

Named is not running. That is why when i give the command service named restart, it shows failed. How can i troubleshoot the error??

as above, are you sure it is fully up to date?

There's very little reference to that dbus error online, have you restarted dbus? Rebooted?

When i used service named status, it gives me this error.

rndc: connect failed: 127.0.0.1#953: connection refused
named is stopped
