Hello Experts, I have putty.exe on my desktop so if I will go to command prompt and then to C:\Documents and Settings\user\Desktop location and execute following command it will launch the Putty window of telnet connection to server specified: putty.exe telnet://10.3.215.15/ I am trying to launch the putty to telnet to specific server using following but its not working for me: <?php $securecrt = "C:\\Documents and Settings\\user\\Desktop\\putty.exe telnet:// 10.3.215.15/ "; exec($securecrt); ?> If I try following then it launches the putty application but will have to provide the host name or IP to login: <?php $securecrt = "C:\\Documents and Settings\\user\\Desktop\\putty.exe "; exec($securecrt); ?> Not sure if I am missing something very basic, It will be great if someone can help with this. Thanks, Devang
