RE: zenmap as root error
From: Aaron Leininger <rilian4 () hotmail com>

I apologize for the delay in getting back to you all on this, my day job has been overwhelming lately. 

I tried your suggestion with the following result: 
nonroot$ sudo su -
myrootprompt# export DISPLAY=:0
myrootprompt# zenmap
Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
Segmentation fault

I did some digging on this error in google and I found a response suggesting the error stems from trying to run 
something in an x-session that is owned by another user. 

I opened a root-shell directly and ran zenmap again 
myrootprompt# zenmap
With the result that it opened normally. 

Can anyone tell me why I am seeing this behavior? Why does zenmap segmentation fault out if I open a normal shell and 
run: sudo zenmap but if I open a root shell, it launches fine. This seems odd to me. 

Thank you all! 
Aaron


Hope this helps you. Perhaps you already think about this, but...
Try to set the DISPLAY variable before.

If I don't set it before, I have the same output:

#zenmap
Segmentation fault

But after I set It, it works like a charm:

export DISPLAY=:0

and in my linux I also do as my non-root user,   xhost + 
(checkout your firewall's rules before) 

I'm using debian so I don't know if Suse sets the variable by default.

Never the less, zenmap should'n break like this.
I'm attaching the zenmap debug output in case someone needs it. (export 
ZENMAP_DEVELOPMENT=1)

Linux Aquaviva 2.6.24-1-686 #1 SMP Mon Feb 11 14:37:45 UTC 2008 i686 GNU/Linux

I have been working for a while on getting zenmap running on my SuSe 10.2
laptop. I have had some python setup issues which I think I have resolved
and I can now run zenmap as a regular user....However, when I run zenmap as
root I get the following:

myprompt#>zenmap
segmentation fault

I tried it from my regular user with sudo and got the same results.
I'm running nmap 4.60 compiled from the main tar.gz. I didn't see any
errors during compile.

Any suggestions?

Thanks,
Aaron
