Wouldn't that be like very insecure? I wouldn't need to root the server in order to use that connection!
Example Scenario: I generate a key pair from server local to server remote, and place the auth key in a 0400 moded file owned by root, but accessable by "nobody" (as this is the uid I will be sshing out as). Multiple people have access to write php scripts on this server. Now *anyone* who is able to execute commands as "nobody" can (very very easily) get from server local to server remote without the need for a password to be entered. Fair enough that they would need to know the address of server remote, and that they would never get the password - but they wouldn't need one either. Just my PoV on security... You could always try investigating SSH wrappers. - Dan -----Original Message----- From: Miguel Cruz [mailto:[EMAIL PROTECTED]] Sent: 05 May 2002 07:44 To: [EMAIL PROTECTED] Subject: Re: [PHP] RE: SSH On Sun, 5 May 2002, Insomniac Admin wrote: > You could use "popen" to open a ssh process and wait to be asked for > the password etc... Remember to check the RSA key pattern. My experience, at least with recent SSH versions, is that they try very hard to verify stdin is an actual pty before accepting a password from it. This is specifically to stop people from storing passwords in cleartext. However, you can do wonderful things with key pairs. Read all about ssh-keygen. We have servers that need to do things on other servers. We store the private keys in 0400 files owned by root, create root-owned shell scripts to ssh into the remote servers and execute specific commands, and allow the web server to run those with sudo. Not perfect, but reasonably secure as long as nobody r00ts the web server. miguel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
