Problem with DM when using IP address not Hostname

[rpalmer68]

I've been struggling with a problem for a couple of days now where DM was working on my NR (.86) laptop but not on my PPC (.86) or development machine.

Today I noticed that the PPC and development machine had the girder plugin hostname set to the IP address (192.168.1.11) while my laptop had the hostname set as htpc1.

I changed the development PC to the hostname (htpc1) and then my DM calls worked correctly.

Here is the log for when the DM call DOES NOT work (when IP address is used)


00000144 28.05922508 [2472] 17:00:22.951] Lua (Unknown)] Error running lua chunk

00000149 33.75037384 [2472] DM: Got a DM host htpc1

The Lua concole logs DM: No DMHost!

Is there a way to sort this so I can use "htpc1" in my DM calls but have the IP address set for the girder plugin?

At the moment I have to use the IP address on the PPC as for some reason it can't resolve the htpc1 hostname, and I don't know how to get it to resolve the hostname.

Cheers

this problem was also reported at the end of this thread

the problem you are seeing with the ip address also happens if you switch between lower/upper case...

Marcel,

What do we need to change/fix here?

[mhwlng]

As mentioned in the other thread, you need to fix GetInstance in NR :

local girder = NetRemote.GetPlugin('Girder')
DM.Instance = girder:GetInstance(host)

so that host is case independent and works for both name and ip addresses..

The error is caused by a non existent global host variable in :
DM.Log(6, "Couldn't find instance for "..host)

Is there a work around for this problem until it's fixed or is the fix close?

My PPC is basically useless now as most of my system controls have now been converted to use the DM.

Thanks

While a fix is being worked on, I found this description on how to create a hosts. file on a Windows mobile device so it can use the hostname instead of the IP address.

http://www.amset.info/pocketpc/hosts.asp

I have run it on WM5 and it works fine!
