Apart from the init.d scripts just running transmission-daemon manually will give you access to the web ui. Did you install the packaged Transmission first? And then you might try a brand spanking new web interface by yours truly. Shift: A minimalistic approach to maximum control of your Transmission.
@tbarat: Memory issues could be related to many things. Using the web-UI is usually not one of them. Transmission is supposed to have a very low memory footprint. The only configurable memory option I know of is the cache size.
my item is a broadband router and it has a small memory capacity 128MB
I see the losing memory in the overview webpage on my router webserver, when the transmission web gui is downloading a torrent.
