hostname vs IP address

tumutbound · Post by **tumutbound** » Mon 05 Jan 2015 8:05 am

The beta has been running on my Raspberry Pi B+ for nearly 12 hours without any warnings messages - once I got the Cumulus.ini sorted out.

One thing I've just noticed is that I can connect to Cumulus server via the ip address but not the hostname. e.g.

http:192.168.1.128:8998 works but:
http:plusberry.homelan:8998 gives an error:

Bad Request (Invalid host)

Host is in the DNS and I can ping, ssh etc to it by name from other hosts.

Using the host name works OK for me, so there must be something different about the way our systems are set up. I don't know what that is, though...

I assume you are actually typing http://plusberry.homelan:8998

Yes, typo in the post

Still trying to track this one down. web server on the same host doesn't give this error.

Using 'localhost' or '127.0.0.1' doesn't work for me either. Is MX only bound to the IP it spits out at initialisation?

Yes.

So far:

hostname is correct (plusberry)
/etc/nssconf has the following line:

hosts: dns files

so DNS is being referenced before /etc/hosts

Dynamic DHCP updates DNS and other hosts can ping/dig plusberry.homelan

Even tried putting a line in /etc/hosts:

192.168.1.155 plusberry.homelan plusberry

Still get same error.

Access via IP address is OK

Is 'plusberry' the actual host name of the computer? I can connect using the 'real' host name OK, but 'localhost' does not work.

A hostname command returns:

plusberry

I can't use localhost as I'm connecting from another computer, not the Pi that Cumulus is running on.
