Topic: SME8 / SAIL 3.1 DNS not working

[fred2k3]

Hi,

We're using SAIL 3.1.1-22 for a VoIP server.  Everything was working ok until last week, where suddenly DNS has stopped working.

I have seen that SME8 is now End of Life, and I'm wondering if the DNS servers which my version uses have been decommissioned or something? 

Is there any way for me to get this working again without a full upgrade?  I tried yum update but it can't perform it before of the DNS problem!

Any help appreciated,
Thanks

Well you have a number of issues.

V8 was EOL a long time back. You really should upgrade.

For Sail there is a foro here or via

Notwithstanding that, global DNS still seems to be working

So the question would be how is your DNS set up? Which DNS servers do you use? Has your router or ISP changed something?

Thanks for reply.  Yes realise we're quite out of date, everything's been working for years though, so didn't want to make unnecessary changes!

I actually have no idea what DNS server addresses were being used, it seems to be hard coded into the O/S somewhere, and we were specifically advised not to specify the "corporate DNS" setting during the configuration process (indeed when I did try and change this, there was no Internet access for the clients).

Anyway, have fixed this by adding a different DHCP server where I can specify the DNS.
