Solved: Media players report PS3 Media Server [unknown host]

[skellert]

{edit] - Solved by myself finally.... problem wasn't ps3mediaplayer, but with DNS name resolution. I toyed with so many parameters, I can't say for certain what fixed this. I think it may have been incorrect config of my F15 DNS/DHCP server.... I'm running 'named' for DNS resolution, but noticed that DNSmasq was also running on same server (in failed state). Perhaps this was the root cause?

Interestingly, the PS3 Media Server identity reported by my media players is now of the form "PS3 Media Server [Dads Computer]", where as way back in the distant past before my problems appeared, it used to report "PS3 Media Server [172.16.1.2]".

In any case, you'll find my 1.50 ps3mediaserver config outlined in the posts below, and have previously worked with 1.20, 1.30 in essentially this form.
[/edit]

Hi,

I've been running various releases of Fedora (currently F15) and various releases of PS3 Media Server (currently 1.50.0) for several years.

My problem has been bugging me for a long time, and several PS3 Media Server releases.... PS3 Media Server fails to resolve the hostname of the fedora box, and because I've got TWO fedora servers on my home network, my media players each report the same thing - so I can't tell which is which.... (ie the media players all show two servers called "PS3 Media Server [unknown host]") The host names used to resolve to their IP addresses, but some time a long time ago it stopped working for me.

I've tried adding the IP address of the interface to /etc/hosts along with a name - but this doesn't change the behaviour.

I've changed the host line on /etc/nsswitch.conf to read

Code: Select all

hosts: files mdns4_minimal dns

but this doesn't change the behaviour either.

I've deleted my PMS.conf and had PS3 media server create it again. No change in behaviour.

I've tried binding to an IP address rather than to the interface (I'm using br0), but no change in behaviour either.

I'm guessing its got something to do with the way that java resolves names, but I'm no expert in this. Can anybody help point me in a new direction?

For what its worth, here's my log output (scroll down to see error at 13:09:39.195)

I can add a little more information to the post above....

When running PMS.sh from the command line, the following error indicates that its found the hostname, just not the IP address....

Code: Select all

and I can confirm that the error is of the same form on the other server (with different hostname) too. The hostname is the one specified in /etc/sysconfig/network or assigned via dhcpd's 'get-lease-hostnames' option.

[meskibob]

I don't know linux well, but I believe the hostname needs to be configured in "/etc/hosts" and it should be the FQDN.

[skellert]

Thanks for the suggestion.... I've tried this avenue and it doesn't work.

In the interests of full disclosure, here's my /etc/hosts

Code: Select all

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain   localhost
172.16.1.2      DadsServer.MY.DOMAIN.PATH DadsServer
::1     localhost6.localdomain6 localhost6

I've also got a working named on one of my servers, that correctly serves the IP addresses of all local host names, with and without my domain. (ie I can ping DadsServer from any machine on my home network, and the local DNS will resolve that name correctly to its local IP of 172.16.1.2)
