TTL field and DF flag addition

[fdauti]

Hello and thank you for your development of icmplib.

I'm using it as part of a tool for diagnostic purposes. I wanted to ask if it is possible to include these two parameters as part of future development. First one is a "df" parameter as a feature, so that if set to True, will enable the Don't Fragment flag in the IP header. Second one is a ttl return value, corresponding to the ttl field value in received packet. Or maybe there is something related to the above but I'm missing them.

Thanks again and regards.

Hi @fdauti,

Thanks for using icmplib!

Adding the DF flag should be possible. However, not having enough time to devote to icmplib at the moment, you will have to wait a bit.

For the TTL, there have been several requests in the past on this subject but I do not understand the point of retrieving this information (the remote equipment responds with an initial TTL which may vary). Moreover, not having access to the IP header in IPv6, I can only retrieve this information in IPv4.

Hi, I would also be interested in the DF bit for testing respectively verification of fragmentation in the network.

Cheers, Matthias

Good afternoon I’ll also say that I would very much like to see in the library possible checks without fragmentation.

I Opened an almost Duplicate of this for a DF flag - i think an additional option in the ICMPScoket or ICMPRequest would be the right place - would you object if I did a clone/fork and attempted to build a Pull request to add this feature, or would you prefer to keep development entirely in house ?
