Tried it, no effect.
I've found that using TTL rather than IP_TTL stops the vendor error appearing, but has no effect. Searching around found 15 as a possible value for TTL, but that did nothing either.
setsockopt (SOCK,0,15,4);
This gives no errors, but Wireshark shows that the TTL is still at 64 :/ | [reply]
