[mpls-linux-general] Re: Ethereal crashes immediately

[murat <te...@ya...>]

Hi all.
 
I've got a bit more specific info on when ethereal crashes.That is when I just create an incomming label with the following line only ( without creating outgoing label, adding route...):
 
root# mplsadm2 -A -I gen:16:0
 
 That line only is enough to make ethereal crashing.
When I remove the label with:
 
root# mplsadm2 -D -I gen:16:0
 
ethereal works again. The same problem with tcpdump.
 
I'm writing a thesis (time pressure) and have to use a cost free sniffer. If there are any alternatives please tell me. The best would be to make ethereal work.
 
Again many thanks in advance and regards.

Hello guys,
  
 I use FC 2, kernel 2.6.8-1, mpls-linux 1.938, Ethereal 0.10.7. Everything installed like
described at mpls-linux.
 Problem is Ethereal. It works when I capture IP packets. It crashes as soon as I want to
capture MPLS packets. 
 I set a path between two routers (/proc/sys/net/ipv4/ip_forward = 1): 
 mplsadm2 -A -O 0
 mplsadm2 O 0x2 -o push:gen:16:set:eth0:ipv4:192.168.30.2
 ip route add 192.168.30.0/24 via 192.168.30.2 spec_nh 0x8847 0x2
 mplsadm2 -A -I gen:17:0
  
 mplsadm2 -A -O 0
 mplsadm2 O 0x2 -o push:gen:17:set:eth1:ipv4:192.168.30.1
 ip route add 192.168.30.0/24 via 192.168.30.1 spec_nh 0x8847 0x2
 mplsadm2 -A -I gen:16:0
 
  
 Now when I start ethereal, and klick "Edit-Preferences" or "Capture-Start" - ethereal
crashes immediately, the messege in the terminal is "Aborted".
 Etereal works again when I delete the path.
  
 Thanks for any help in advance and regards.
