Hello Dears,
I am trying to use IBR-DTN in my thesis and I have following problem:

While trying to use deamon.
The error I get is:
ERROR ApiServer: Cannot bind to socket with address [::1]:4550

I tried:
1-disabled ipv6 then (ipv4 port listener also gone)
2-change dtndconf  bind interface to : 127.0.0.1
3- almost checked all mailing list and FAQ of IBR-DTN.

still nothing... please help me
