Re^2: Net::RawIP - invalid checksum ?

[willambender]

Negitive. I now get.. (Defaults to TCP, src/dst ports are now 0)

14:46:44.553547 IP (tos 0x0, ttl 60, id 35744, offset 0, flags [DF], p
+roto TCP (6), length 40)
    192.168.10.10.0 > 192.168.10.20.0: Flags [DF], cksum 0xcd50 (incor
+rect -> 0xd550), seq 0, win 65535, length 0

If i use your example and just change...

my $packet = new Net::RawIP({udp => {check => 0}});

Or even..

my $packet = new Net::RawIP({udp => {}});

I still get a bad checkdum...

4:47:22.542872 IP (tos 0x0, ttl 60, id 35885, offset 0, flags [DF], pr
+oto UDP (17), length 35)
    192.168.10.10.6544 > 192.168.10.20.514: [bad udp cksum 0xb59d -> 0
+xbd9d!] [|syslog]

Well. Like I said, I couldn't test it. I was just trying to help with a possible alternative.

I notice after reading both the docs, and source. There's precious little, regarding the check option.

OTOH I notice
Net::RawIP::opt
and
Net::RawIP::udphdr
Perhaps experimenting with them, might yield some positive results?

Just a thought. Not being able to test it myself. I'm afraid that's all I got.

Best wishes
