Hi Jane, >> What exactly is Remote login? Does it mean what I think it means, >> maily that I can "log in" to my account on the iMac using my >> iBook? If I am doing so on my own iBook, can someone else log into >> antoher account at the same time using another iBook?
Yes, if you have enabled remote login for your computer, other users can log into accounts on that machine at the same time through the terminal application. You can't use Telnet for these logins. Instead, you can use SSH (Secure Shell) and its file transfer counterpart, SFTP (Secure FTP) for your remote terminal sessions. When you remote login it is as though you were running a terminal on the remote machine, and you can have multiple sessions (or even multiple logins onto your own account). (This would be a good time to review Shaun's mp3 files on using Terminal <smile>.) SSH and SFTP encrypt your sessions, so even if you log into your second machine on a wireless connection both the information you type and your login/password sequence are secure. (This does mean that large file transfers will be noticeably slower through SFTP than through direct FTP because of the encryption). Assuming you have Remote login enabled, just open a terminal session (Command-Shift+U from Finder to go to the Utilities folder, interact, Type "T" to go to terminal, and open with VO-keys+space or Command-o). If you want to log in as "jane" on your iBook, and you know that its IP address on your network is 10.0.1.3, for example, then just type: ssh -l jane 10.0.1.3 or I prefer to use the format with the AT sign used for email: ssh [EMAIL PROTECTED] (The Mail Archive will block this, so read this as: ssh jane AT 10.0.1.3 where "AT" is replaced by the at sign and there are no spaces around the symbol). You'll be prompted for your password on the remote machine. There are other ways to set up SSH, but this is probably the easiest way for you to start. If you want to use SFTP, just replace "ssh" with "sftp" in the above commands. Once your are logged in, you will have to change to the directory you want to transfer files to or from with commands like "cd". Then you can "put" or "get" files. Wild cards work for file names. If you're distributing IP addresses with a local AirPort or other wireless router you can check the address of your machine through System Preferences. VO-keys+m to move to the Apple Menu, arrow down and type "Sy" to go to System Preferences. Tab to "Network" and VO-keys+space to select. Either tab or VO-keys+ right arrow to the second popup button that selects what information is being shown. If you don't have your mouse cursor tracking your VoiceOver cursor, move mouse cursor to VoiceOver cursor with Control-Option-Command-F5 (laptop users may also need to press the FN key depending on how your preferences are set). VO-keys+shift on the popup button and type "A" to set this to AirPort and return. VO-keys+right arrow to the TCP/IP tab and VO-keys+space to select it, then VO-keys+right arrow to read off the IP Address. If you're on a wired connection, choose "Built-In Ethernet" instead of "AirPort" on the popup button, and go on to check the TCP/IP tab. An alternative to using the TCP/IP pane of your AirPort under Network in System Preferences to find you IP address is to use a unix command in terminal: ifconfig | grep broadcast | say (You probably won't find this easy to remember, though <smile>). This is the interface configurator (ifconfig) for setting up and querying TCP/IP (transmission control protocol/internet protocol) interfaces. The above command pipes the long output of the ifconfig command into a pattern search for the line that gives the IP address your machine is broadcasting. Only the first part of the line following inet is the address: inet 10.0.1.3 netmask 0xffffff00 broadcast 10.0.1.255 If you need to hear the results of the ifconfig command again, press your up arrow and return. To allow remote login access to your computer, open System Preferences and go to Sharing. Choose the Services tab. interact with the table, and select the Remote Login option by checking the box. HTH. Cheers, Esther
