======================= The Course Linux Server ======================= -IAN! idallen@idallen.ca The Course Linux Server at net2003.idallen.ca is a dual-redundant high-availability cluster of two machines located in the basement of my house in Centretown. (Algonquin ITS will not let faculty run Internet-accessible Linux servers on campus.) Any issues you have regarding the Course Linux Server must be dealt with *only* through your instructor. Neither Algonquin ITS nor the Help Desk know anything about these Linux machines. All issues, including password resetting, must be resolved directly with your instructor, either by posting to the appropriate course news group or by sending email. The Linux machines are located behind a firewall. Any time you connect to this machine remotely using the SSH protocol (including using SCP or SFTP or PuTTY), you must use the port number "2003" to pass through the firewall. If you forget the port number, you will get rejected or your password will not work. -------------------------- Connecting from Unix/Linux -------------------------- To login to the Course Linux machine from the shell prompt at another Unix machine (including from Knoppix or from Macintosh OSX), use the SSH command with the -p (lower-case) port number option: $ ssh -p 2003 -l abcd0123 net2003.idallen.ca [...answer yes to accept the host key, if asked...] [...enter your Course Linux Server password...] Replace the userid abcd0123, above, with your usual Algonquin userid. Your instructor can tell you your special Linux password. The options "-p" (port) and "-l" (login userid) must be lower-case letters. You may also specify your userid in front of the host name: $ ssh -p 2003 abcd0123@net2003.idallen.ca If you need your password reset, see your instructor. Do not go to ITS. Alternate access (in case net2003.idallen.ca is not working): $ ssh -p 2003 abcd0123@alt.net2003.idallen.ca (note the "alt." in front of the host name) Faster connection (on Algonquin campus only) -------------------========================- On-campus at Algonquin, you may find this connection to the Course Linux Server via local machine 10.50.254.230 faster: $ ssh -p 2003 -l abcd0123 10.50.254.230 -or- $ ssh -p 2003 abcd0123@10.50.254.230 The local 10.50.254.230 address only works on campus at Algonquin, or via the Algonquin VPN. When on-campus, using 10.50.254.230 is often faster than using net2003.idallen.ca. Alternate access (in case port 2003 is not working on campus): $ ssh -p 2004 abcd0123@10.50.254.230 (note the use of port 2004 instead of 2003) ----------------------- Connecting from Windows ----------------------- If you use Windows (e.g. in Algonquin open access labs), you must use the PuTTY program (or other SSH-capable program) to connect to net2003.idallen.ca or 10.50.254.230 using the SSH protocol and port number 2003 (not the default ssh port 22). PuTTY requires you to choose the protocol (SSH) *before* you set the different port number (use port 2003 for net2003.idallen.ca or 10.50.254.230, or alternate port 2004 for 10.50.254.230). Choose SSH before setting the port. Most versions of PuTTY default to using SSH so that all you need do is give the host name and port number. -------------------------- Copies of the Course Notes -------------------------- You can find a copy of all the course Notes files for NET2003 on the Linux Server under directory: ~idallen/public_html/teaching/net2003/ Pick the sub-directory corresponding to the current term. You can copy files from this directory to your own account for modification or study, if you like. (To avoid plagiarism charges, you must credit any material that you copy and submit unchanged.) --------------------------------------------- File Transfer to/from the Course Linux Server --------------------------------------------- See the Notes file: file_transfer.txt
