I am currently on core update 203.

I don’t know if this started with 203 because I just noticed it.

I can’t seem to use names any more to refer to PC’s on my net. I’m pretty sure it was working.

I have all my nodes set to fixed leases and names defined for each.

I can, for example, “ping [google.com](http://google.com)” which, of course is outside my net, but “ping ” where is on my green network fails. I can ping and ssh with the ip address, no problem.

Is my DNS buggered some how?

Since I don’t when or why this changed, I’ve no good idea where to start to figure what to fix.

With CU203 the remarks of the DHCP fixed leases definitions are not used as host name anymore.  
There are two ways you can get a name

- the client sends a name
- you define the name/IP association in ‘Edit Hosts’ WUI page.

See also discussions, mainly the CU 203 released thread.

Sorry. “WUI page”?

NVM, I found it.

Thanks!

So, is the correct way to manage the host names for any device that can’t, won’t, or doesn’t send the host name with a DHCP request to manage the ‘Edit Hosts’ WUI page?

Adding the fixed lease’s hostname to the “Edit Hosts” list did not resolve the issue in my instance. The hostname still does not get resolved (also not after a restart of ipfire). Command host still yields the following result:

Host not found: 5(REFUSED)

Facing this (and other) DNS issues since Core-Update 203.

If you added your entry as  
`<name>, <interface domainname>, <fixed leases IP>`  
it should work.  
Otherwise it is general bug ²’Edit Hosts’ entries are not included in local name space" to be reported to bugzilla.

Works today without any changes. Looks like it took a while to propagate or so. Thanks!
