Dear Webmaster

 

When the tcpdump command was executed hereafter, the network was cut. 

 

# tcpdump host (192.168.1.2 or 192.168.1.4 ) and port (20 or 21) -w
/var/log/tcpdump.log

 

It succeeds occasionally though it fails no matter how it executes it. 

 

The environment is CnetOS5.5 that operates on VMware Player. 

 

Is there a problem in the format of the command?

 

The following logs are output to the messege log. 

 

Mar 2 02:07:49 localhost kernel: audit(1299049669.539:3): dev=eth0 prom=256
old_prom=0 auid=4294967295 ses=4294967295

 

This might be displayed on the console.
