tcpdump error message

[schotten]

When trying to run tcpdump as any user other than root on an AIX4.3.1.0 system I get the following message; tcpdump: error loading /usr/lib/drivers/bpf. I have tried changing permissions on both files but the results reamin the same. Other than allowing a user root access (not in my lifetime) what can I do to let them run tcpdump. Is my only option to make them part of the bin group?

Thanks in advance for the help.

Hi,
the access should be controlled by the permissions on /dev/bpf<number>.

Greetings

You're correct the /dev/bpf0,1,2, and 3 files controll access. the permissions on them are cr--r--r-- and ownership is root:system. The user belongs to system and bin groups. Seems to me they should be able to run the command successfully.

Thanks for your reply
