This book is quite good. It was my first introduction in this area.

I'll try it next. Thanks for the suggestion :)

Thanks for the feedback :)

Thanks I'll look into this :)

Normally, an ethernet or wifi restricts an MTU of 1500. I use ping packets accordingly

With even ICMP you can send/receive large messages. There is no restriction on the maximum payload length.

That's good news for me. :)

I tried using some but couldn't get them to work. Probably because many were developed long time back. There have been many recent changes in the kernel.

I haven't tried comparing both. I don't have much resources. All I can say is that using icmptunnel, one couldn't differentiate whether it's using tunnel or direct internet. Hence ICMP tunneling was very fast.

Although I'm interested in comparison as well :)

Yes. In my opinion they should restrict the payload size of an ICMP message. Blocking all echo/reply can have adverse impact on other applications as well.

I have tested it. Internet speed difference is negligible. Yup DNS tunneling apps can also be used.

I agree that some captive portals/firewalls do block ICMP but still I've seen many in my country which don't.
