Hi Simon,
thanks for looking into this. I did some more testing yesterday and today and
found the same like you.
My problem now after disabling the local check is, that in send_ua at "if
(libnet_write(l) == -1)" I get the following glibc error:
*** glibc detected *** free(): invalid next size (fast): 0x00000000005042e0
***
Aborted
in gdb I get the following bt:
*** glibc detected *** free(): invalid next size (fast): 0x00000000005042e0
***
Program received signal SIGABRT, Aborted.

The IP Adress is set correctly, but the checks to verify fail.
For your information the ldd of the binary:
