Package: linuxdcpp
Version: 1.0.2-1
Severity: normal

When two clients connect to each other through SOCKS proxies and both clients
have reverse port forwardings from their respective proxy servers, linuxdcpp
detects both users as being in passive mode (firewall icon) and does not attempt
to connect them; instead it says "Can't connect to a passive user whilst in
passive mode!" to the user.

StrongDC++ detects both users as passive (firewall icon) but still attempts the
connection and succeeds.

To replicate, do the following for each client:

$ ssh -fNT -D [X] -R *:[Y]:localhost:[Y] [user]@[host]

- where [host] is a sshd that **has reverse port forwarding enabled.**
  - /etc/ssh/sshd_config needs to contain "GatewayPorts <no|clientspecified>"
- have each client use localhost:[X] as a SOCKS proxy (resolve names too)
- have each client listen on port [Y]

(X and Y can be different for each client. note that if they are both connecting
to the same host, Y *must* be different)

the following commands can be used to make sure the reverse tunnel works:

client_A$ nc -l -p [Y]
client_B$ telnet [host] [Y]

B's input should appear as A's output.

In this setup, A and B can both receive incoming connections, so both users can
be in active mode, even though both are behind proxies.

However, if A and B connect to a hub and try to download from each other,
linuxdcpp with give the aforementioned error message and aborts the connection,
whereas StrongDC++ performs the connection and succeeds.
