Can't ping hostname

[satimis]

Hi folks,


Machine-1
OpenVZ
Ubuntu 8.04 Hardy - Host
Ubuntu 8.04 Hardy - Guests


Machine-2
Xen
Debian Etch - Host
Debian Etch - Guests


Both machines together with their guests are working. They can ping and ssh-connect each other on IP. But they can't ping nor ssh connect each and others (both local and remote machines) on hostname. I have been playing around on hosts, hostname, resolv.conf, mailname, etc. for 2 days without a solution. Please help. TIA

Is hosts configure for the systems?
Is resolv.conf configured for the systems?
What does host.conf look like on all systems?
Are you running a DNS server?
What does nslookup give you for each host?
What does dig give you for each host?

Hi Robert,


Putting all IPs and hostnames on /etc/host works. But there will be a long list if running 100 servers as guest on each virtual machine.

Are you running a DNS server?

No. Any pointer on its setup? TIA

Use your package install tool to install Bind. Then look at the examples and read this book to get things setup.

Noted with thanks


Edit:

"winbind" is another option. Its setup is very simple.

I would never suggest using an inferior product.

@Lazydog: I thought the *same* thing...

Most admins spend a lifetime trying to *get rid of* noisy Windows broadcasts - I have no idea why someone would choose to *add* them to their network.
