libpcap/tcpdump and HP's DLPI implementation
Apparently, the only libpcap library that I can find doesn't fully support HP's DLPI implementation. I can't capture the outgoing packets when I run tcpdump on my L-Class. Does anyone have a libpcap that works, or know what needs to be modified in the code in order to get it to work?
TIA,
Jim

Hi Jim:
Must you absolutely run tcpdump? You might want to try ethereal...

better yet, follow the thread:

nothing wrong with me that a few lines of code cannot fix!

Re: libpcap/tcpdump and HP's DLPI implementation
I could use ethereal if the program didn't core dump every time I try to specify /dev/dlpi0 as the interface to monitor.
I finally did find what appears to be the answer to my question about why I couldn't trace outbound packets. I just have to test and make sure it actually works. Buried at the end of the readme file for patch PHNE_21687 in the "Special Installation Instructions" section was this little blurb.
"To trace the outbound packets, please do the following to turn on a global promiscuous switch before running the promiscuous applications like snoop or tcpdump:
adb -w /stand/vmunix /dev/mem
lanc_outbound_promisc_flag/W 1
(adb will echo the result showing that the flag has been changed)
$quit
"
