I've just installed Ubuntu 6.10 server and am having the same problem, can login on the server, but cant access it from another PC on the network. Get a login box through IE but nothing works.
My bad, im a newb so screwed up. I was being impatient, two problems: 1. I hadn't created an admin account for the site. 2. I was having the XP login delay issue where nothing happened for about 15 secs then it would login, by opening port 113 on my workstation I can login and browse the FTP really quick now.
I don't know how administrator got there. The username is web1_admin and thats what I was using to login to the ftp.
Yup..I had to re-set up the FTP on the client machine because my Windows machine died. Now i'm on the Mac. So the username is web1_admin.
