GUI over a 28k dialup? ouch. there's no network connection at this remote site? its going to be really really slow over dialup. I'm talking minutes to paint a screen at 2-3kbyte/sec serial speeds (a 1280x1024 24bit desktop is 3.6 million bytes). use a really simple theme on the desktop with no shaded borders, no backgroun graphics ('wallpaper'), etc. Sending a single full screen 1280x1024 photographic image could take a half hour or more. FreeNX is probably your best bet. i've never set it up, so you'll need to find someone elses HOWTO ... NX protocol runs over TCP/IP networking, so you'll be setting up your modem (I still recommend a serial modem) to answer a PPP dialinn TCP session, which you'll connect to with a PPP dialup session much as we did for the internet in the days before broadband. linux can be completely managed via shell. NONE of the dozens of unix servers I manage have any sort of console screen attached to them.
