Technically, it is not possible to log in with a space in the name (main_cnx_handshake.c, line 584). It is probably only a character displayed as a space but not a real space.

Currently, only 4 characters are forbidden: the space, the dollar, the pound (used in regexp) and the pipe. If the client cannot save the share list, it is a client problem. DCTC has fixed it for the only unusable character in un*x path, the slash.

a couple of charachters that should be disallowed in the username are " \ / : * < >
This will cause problems when people are trying to fetch filelists from them becase that the clients cannot create a file (in windowze atleast) that has any of those charachters.

I don't know how it's possible. Somehow users with an space in the nickname are able to enter the hub.
As well they don't send an MyINFO but the connection is not closed...
I've already tried to modify the 'validate nick' stage of main_cnx_handshake.c but without success...
the invalid clients seem to be modified edonkey-clones able to use the dchub protocol.
