Hi, I installed Fedora 4 (kernel version 2.6.17.13). When I plug in my ROKR E2. Fedora connects to the phone (the phone runs on linux too) automatically, and then I use ifconfig -a to show up the usb0. The address of usb0 is assigned automatically by DHCP. I modify this address to 192.168.1.2 by "ifconfig usb0 192.168.1.2 up", I verify the modification by using "ifconfig -a" again. Then I ping the address 192.168.1.2, it succeeds. But at last when I telnet to the phone, I got the prompt "Trying 192.168.1.2... telnet: connect to address 192.168.1.2: Connection refused. telnet: Unable to connect to remote host: Connection refused" I am sure that the telnet service in the cellphone is started and the port is the usual port (23), and no authority requirement for the telnet service. I did successfully telnet to the cellphone once. That was the first time that I pluged the usb line to my linux laptop and done the above procedures. However later on, I can not telnet to the cellphone any longer when I plug it again. And I found when the linux starts, the system fails to automatically load usb0. I don't know what I'm doing wrong, I did not change any other configurations between my first try and subsequent tries. Why the first time I succeeded, and later on failed? Please help! I need to telnet to the phone and finish my job. Thanks a lot newie-fedora ____________________________________________________________________________________ Yahoo! oneSearch: Finally, mobile search that gives answers, not web links. http://mobile.yahoo.com/mobileweb/onesearch?refer=1ONXIC
