Some clients have the feature to do a direct connection to another client to do a file transfert without using any server feature. I don’'t know if Miranda has this feature, you should look to miranda features or ask it to miranda user mailing list.
We use Miranda and Wildfire. We have had no trouble sending files between two clients. We are using 4.0.2 with various plugins. I can send you a list if you are interested.
I was tring to migrate to Jabber (Wildfire) plus Miranda and I had exactly the same problem. Transfers originated by Miranda doesn’'t work or send corrupted files even though it receives files from Spark Client. (Miranda 0.4.0.3 / wildfire_2_5_1).
Proxy configurations doesnt seem to be necessary inside a local network. Spark does simple transfers with no special configurations.
I was using ICQ Groupware Server (on winXP) with Miranda client and I was able to do transfers with no problem. But my ICQ server became unstable on XP (server closes) and I could not make it work on Win2k (it installs but server do not even start).
I also tried to download a Jabber DLL from Miranda plugins because I was not sure wich one was newer, the one inside Miranda 0.4.0.3 or the one from plugins download page but made no difference.
I believe that the problem is not in Wildfire because transfers occur thru spark client.
Also had Miranda crashes typing messages to a offline registered user.
I was very excited about moving From ICQ GW to Jabeer but we would prefer to use a multi-protocol client as Miranda can do.
We would appreciate if anybody using same configuration could tell something about it.
