unable to lookup mybox via gethostbyname()

[knopx4me]

I have remastered Knoppix 3.8. It works great from CD with all the customizations that I made. However, when I installed it on HD, KDE won't allow me in. It accepts my password but don't allow me in. It keeps showing me kdm logon screen. I selected the command line option and started X with no problems. I got this mail message:

************************************************** ***************************************

Subject: *** SECURITY information for mybox ***

mybox : Apr 8 02:34:13 : root : unable to lookup mybox via gethostbyname()
************************************************** ****************************************
Does any body know what does this mean? And how to solve it?

Hi knopx4me,
I don´t know if it helps, but during the development of the script for remastering the knoppix HD install I have faced this trouble and I discovered, for the 3.7 version at least, that the problem is due to the hostname. In your case I´ve seen you call it mybox and the internal routine 45xsession expects it to be named knoppix. I solved this problem, in my script, changing the following, which you could try on your chrooted environment (problably /knxsource/KNOPPPIX/KNOPPIX):
1 - On the /home/yourname directory I deleted the hidden files >DCOPserver.... If your home is, for instance, /home/knopx4me, do this (on a terminal, logged as su): rm -f /home/knopx4me/.DCOP*
2 - Edit /etc/hostname and change whatever name is inside /etc/hostname (problably mybox is there) to knoppix.
3 - Also edit /etc/hosts and change its first line for this: 127.0.0.1 knoppix localhost.

That´s it! Now produce the compressed file KNOPPIX and the iso image and burn it.
Cheers!

Thanks very much for help. I got it working now by going back to the last working copy. I always keep a copy of the last working iso to revert to it when I stuck with such a problem.
