THanks that is very clear. No, we do not have a web server on the unix box. My manager told me to just write to CGI program on my machine and test it there and after it is good to go he will put it on our web server and it would be avilable for the LAN users in this office. Eventually we would need to make it avilable to our other office locations.
I understand what the security issue is now, thanks. Because I don't have a web server on the unix machine, I can't use LWP::Simple right? Also I will try to research more about the SSH method Matt suggested, but I will have to find out if my the Unix machine supports that. Thanks guys Kelvin -----Original Message----- From: Thomas_M [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 22, 2003 9:52 AM To: 'Poon, Kelvin (Infomart)' Cc: '[EMAIL PROTECTED]' Subject: RE: [Perl-unix-users] Perl and UNix Telnet is not considered secure because a password is transferred over the network in plaintext. On a protected network this is sometimes not a concern. However, if you created a special login on the Unix machine that instead of executing a login shell performed 'cat yourfile' and closed the connection, then the security would be no different than FTP or HTTP. Now, about your LWP question: LWP (or LWP::Simple) is a simple way to retrieve a file on a web server. To use it, you would need a web server on your Unix machine set up to be able to serve the file. But if you have that set up already, you really would be better off putting your CGI script on the unix machine. You haven't told us why you aren't considering this option. -- Mark Thomas [EMAIL PROTECTED] Internet Systems Architect User Technology Associates, Inc. $_=q;KvtuyboopuifeyQQfeemyibdlfee;; y.e.s. ;y+B-x+A-w+s; ;y;y; ;;print;; > -----Original Message----- > From: Poon, Kelvin (Infomart) [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, January 22, 2003 9:36 AM > To: 'Martin Moss' > Cc: '[EMAIL PROTECTED]' > Subject: RE: [Perl-unix-users] Perl and UNix > Importance: High > > > > Thank you for your advice, but I just want to ask you one > more question.
