DNS issues
| Posted by vip2, 03-04-2010, 10:35 AM |
| Don't know what on earth has happened but been suffering from a downtime due to a DNS issue of some kind. As none of my domains which are hosted on a cPanel server are resolving. Running a check through some DNS sites and I get
and
Nothing has been modified for ages and the only thing I can think of is a possible cPanel update to 11.25.
The begining of my named.conf is like such
Any 1 got any ideas on what I can go now as I've checked and triple checked the settings and they're all the same from when it was working fine.

| Is there actually a line in there for your domain as that config just seems to show a very standard template

| Do you have the domain entries in the /etc/named.conf file OR just the entries you have shown above? Also any error message you receive while restarting the named service?
|

| Yes there is
Next line is for example something like this
zone "wh0a.com" {
type master;
file "/var/named/wh0a.com.db";
};
No errors when restarting named and I have used named-checkconf to make sure there are no syntax errors.

| Do you have any firewall installed on the server.

| Don't see any problems with the iptable rules as well. Have your hosting company OR a server management company to look into the server?
BTW, are you sure all the websites have stopped working from all the locations?

| Well basically all the websites via domain had stopped working on some connections. I would say 80% of users and account owners were affected. Including myself. Yet if I used a proxy or my work connection it was fine.
Considering that I've just ripped to shreds all the configuration files to do with names servers / dns to try and rectify this issue. I decided to go back to my registrar of which I have the nameservers registered with. Done a DNS RESET to their defaults and just configured everything back up nameserver wise.
My registrar is 123-REG and initially a long time ago when this server was setup I think I followed one of these 123-Reg Nameserver guides on getting private nameservers.
Now apart from doing that, I've also gone into the DNS Management option within 123-REG and set two A records with my nameservers in there.
Seems to have sorted it. As I can access the domains hosted on the server and not being forced to use IP addresses.
Phewwww..
Wish I had done that yesterday when I was pullin my hair out.

| Hmm, odd situation. Were the nameserver records returned by the parent servers showing the correct IPs?

| I wonder if /scripts/fixbuggynamed or /scripts/rebuildnamedconf would have helped at all? Hmm...
