Hi, When I use Net/telnet module on target platform SuSE9.2, I got an error message like "Tset: Unknown terminal type network". I also tried to replace "login" fuction with "Waitfor" fuction, but it is still the case. Furthermore, I try to modify the options "Prompt" to another regular expression that matches the prompt of SuSE 9.2, but it still does not work. I used google to search for reasons about this issue. And I found maybe the default terminal type of SuSE9.2 should be modified to make my program work. Have anyone met the same problem? And could anyone give me a hand about how to configure SuSE9.2 terminal type? Additional info: my SuSE used bash shell as default shell. And the enviroment "TERM" is "xterm" and I examined the "/etc/termcap" and found nothing valuable. Thanks a lot! -- Posted via http://www.ruby-forum.com/.
