What do you think the problem is? You didn't read how UDP checksums were calculated, did you? Here is one free clue: Look at the definition of in_pseudo() and where it is used. Use the source. look!

Old tar (v7) and Posix (well, SUSv2) have no dash before the key (the first argument to tar). They take option values from the next arguments in the order the options appear in the key string: tar xfbv file.tar 2 x - no arg f - take next arg (file.tar) b - take next arg (2) v - no arg. Using a dash is a gnu-ism and should be avoided in scripts. harti -- harti brandt, http://www.fokus.fraunhofer.de/research/cc/cats/employees/hartmut.brandt/private [EMAIL PROTECTED], [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

Hi, when trying to intercept UDP packet after changing the protocol number from 17 to a user one (99) in the ip_input.c file. when trying to regenrate the packet after inserting some bit errors an error message appears in the reciever telling that The udp checksum is incorrect even if i just change the ip Header. What do you think the problem is? Thanks in Advance, ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
