"cannot find hostname"
« on: October 04, 2005, 02:35:42 PM »
hi guys,

I just receive 2 errormessages from amule every startup

looks like this:





I just talked to Ken and his statement was to give the machine a hostname....just one prob....the machine already got a hostname (I guess...so how can I checkit?)

so I don't know how to continue solvin the prob ?! Any Ideas :/

Im now running a CVS version recommed by lionel and before it was the official 2.0.3 release...both the same prob

Hmm.  I get my hostname from the DHCP server on the LAN.  I'm not sure what your options are if you don't (if, for instance, your DHCP server belongs to your ISP and they aren't giving your host a name).

There's the "hostname" command, so you could do "sudo hostname yourhostnamehere" in the Terminal, but I don't know if that's permanent or not.  I also think it won't work well because, if I remember the wx code involved correctly, wx really wants it to be fully-qualified like yourhost.yourdomain.co.de or whatever.  And, that won't work to get your local IP (aMule's ultimate goal) because it's not really a registered DNS name.

Frankly, I think it's a bug in our aMule code that we're using the wx functions that we are.

P.S.  Oooooh, shiny!  ;)

hey ken....many thanks...:P

your answer wasn't quite understandable but I think I just know what you're meaning

from my provider I got a dns-server which I just entered in the network settings of mac os x

after that I found the domain NAME for the SERVER which I entered in network settings

so there wasn't any solving effect so I got your typ with "sudo hostname yourhostnamehere"

I entered in Terminal : "sudo hostname mydnsdomain"

and now Amule keeps quite :D

many thx

I'm glad that helped.  :)

Is it permanent across reboots?

I don't know.  I'm sure there's a standard Unix startup file which can run the hostname command automatically on startup.  Or, you can create a Startup Item to do it, too.  However, it feels like we're getting pretty far from The Mac Way of doing things.  I find that when I start getting away from The Mac Way and getting into The Unix Way of doing things like this under Mac OS X, it means I've gone astray.

Who assigned you your DNS name?  Your ISP?  You should ask them if their DHCP server should be telling your computer about its assigned DNS name.  I think it should.  I don't know all that much about DHCP, but I do know that in my company's network that's how it works.

and finally I found out how to make this permanent :P :

1. Open Terminal.app
2. cd /etc
3. sudo cp hostconfig hostconfig.old
4. sudo pico hostconfig
5. Change the line "HOSTNAME=-AUTOMATIC-" to "HOSTNAME=yourdns"
6. Save the file (^O) and exit (^X)
7. Open NetInfo Manager.app
8. Click machines
9. Click localhost
10. Make sure that the lock is unlocked - if not, click on it to unlock it
11. Hit -D to duplicate the localhost entry
12. Click on the 'localhost copy' entry
13. Double-click the value for the 'name' field in the lowerbox
14. Type in the same name as your hostconfig file (i.e. youdns)
15. Reboot

I'm sooo glad now :D

Well, congratulations.  I'm still a bit uncomfortable doing stuff like this behind the OS's back (sort of).  Is this change reflected anywhere in the System Preferences?  If so, you know how to make the change The Mac Way(tm) for the future.

no I couldn't change it by the easy way (in system preferences). so in the config files wasn't the "HOSTNAME=" entry available at all  8o so I had to create it first.

maybe other guys got easierways....but this worked for me now :P and that's what I wanted   :baby:

Hi!

I'm getting the same error:

"Cannot get the official hostname (error 22: Invalid argument)" ?(

only since I've changed from 2.0.3  to 2.1.0.
I can connect to servers and Kad, and furthermore I can get the server list.

All needed ports are forwarded (I think). :]
Connection thru Wi-Fi to an ADSL from Telefónica in Spain.

The error window appear every time I double click at the aMule icon to open it, but never appeared when I was using aMule 2.0.3. Since it never happened before... it isn't a bug?
How could I fix it without the "(ugly) way" ken :baby: links here?

Thanks.

Is not a bug. aMule is requesting the hostname from the O.S. If you ahve none set, is not aMule's fault ;)

I am confused about where this problem is coming from. I am currently (temporarily) using the same ISP as Gomaaz and without any special measures aMule is not complaining about the hostname. This (and the fact that this ISP is the largest one in Germany and noone else seems affected) makes it somewhat unlikely that it is an ISP related issue.

I'm also a bit puzzled by Mace Windu's statement that he only gets the error with 2.1.0 but not with 2.0.3 because Gomaaz initially said that he gets the error both with 2.0.3 and the CVS versions.

I think my wxGetHostname implementation did not get on 2.0.3

But the point is, aMule shouldn't need the hostname and shouldn't use it for the purpose that it is.

Why not? It's ok. That's the way we get the ip. Better ideas? :P
