iodine lets you tunnel IPv4 data through a DNS server. This can be usable in
|
|
different situations where internet access is firewalled, but DNS queries are
|
|
allowed.
|
|
|
|
It runs on Linux, Mac OS X, FreeBSD, NetBSD and OpenBSD and needs a TUN/TAP
|
|
device. The bandwidth is assymetrical with limited upstream and up to 1 Mbit/s
|
|
downstream.
|
|
|
|
Compared to other DNS tunnel implementations, iodine offers:
|
|
o Higher performance
|
|
iodine uses the NULL type that allows the downstream data to be sent
|
|
without encoding. Each DNS reply can contain nearly a kilobyte of payload
|
|
data.
|
|
o Portability
|
|
iodine runs on many different UNIX-like systems. Tunnels can be set up
|
|
between two hosts no matter their endianness or operating system.
|
|
o Security
|
|
iodine uses challenge-response login secured by MD5 hash. It also filters
|
|
out any packets not coming from the IP and port used when logging in.
|
|
o Less setup
|
|
iodine handles setting IP number on interfaces automatically, and up to 8
|
|
users can share one server at the same time.
