- Hello Net
-
- I would value information on ways to abort or terminate an FTP sessions
- data channel. According to the spec the suggested (required?) way is to
- issue an ABOR command on the control channel. However I haven't yet found
- any type of machine that takes any notice of this. They all seem to finsh
- the transmission and then say something like ABOR command successful.
- Obviously this is kinda pointless - or am I just doing it wrong some how.
-
- The other method is to reset the data channel. This works just fine but some
- machines (SRV? unix) also shut the control channel (hence logging you out) at
- the same time. This is kinda annoying.
-
- So can anybody tell me if they have observed this as well - ( my software is
- home grown so I can't really be too sure it isn't my fault). Any suggestions on
- alternate methods?, anyone know of any catastrophic problems with the reset
- method (besides the one mentioned?).
-
- All info appreciated.
