Practical exercises #19

1. Much earlier in the semester we discussed telnet, the generic protocol for remote login. We also mentioned rlogin. However, both of these have effectively been replaced by a far superior software utility, ssh, the "secure shell". You must stop using telnet, rlogin, rsh or whatever you are currently using to do remote login and use ssh instead. Seriously!

2. Find out about and use PGP. Everyone should do this, even if you're not intending to answer the PGP question on assignment 3.

3. Investigate MD5.
