.B MTU issues:
These issues should be solved now, with automatic fragmentation of downstream
packets. There should be no need to set the MTU explicitly on the server.
.SH ENVIRONMENT
.SS IODINE_PASS
If the environment variable
.B IODINE_PASS
is set, iodine will use the value it is set to as password instead of asking

.B -P
