|SSH Port Forwarding|
http://zedz.net/ has RPM and source packages for most of the Unix software discussed in this talk.
OpenSSH can be found at http://www.openssh.com/portable.html.
Putty can be obtained at http://www.chiark.greenend.org.uk/~sgtatham/putty/ : it is a beta Windows-based SSH client. At this time, it doesn't support port forwarding, but it does include a Windows version of scp called pscp.
TTSSH is an add-on for Teraterm. Teraterm is an excellent Windows software terminal emulator, available at http://hp.vector.co.jp/authors/VA002416/teraterm.html . TTSSH is available at http://www.zip.com.au/~roca/ttssh.html .
There are two books we know of on SSH: Anne Carasik's Unix Secure Shell (1999, McGraw-Hill) and Daniel J. Barrett and Richard Silverman's forthcoming SSH, the Secure Shell: the Definitive Guide (due November 2000 from O'Reilly). Anne Carasik is an employee of SSH.
Commonly used ports (which you can check for yourself in /etc/services on most Unix machines) include the following:
ftp-data 20/tcp ftp 21/tcp ssh 22/tcp # SSH Remote Login Protocol telnet 23/tcp smtp 25/tcp mail www 80/tcp http # WorldWideWeb HTTP pop-2 109/tcp postoffice # POP version 2 pop-3 110/tcp # POP version 3 nntp 119/tcp readnews untp # USENET News Transfer Protocol imap2 143/tcp imap # Interim Mail Access Proto v2 snmp 161/udp # Simple Net Mgmt Proto irc 194/tcp # Internet Relay Chat imap3 220/tcp # Interactive Mail Access exec 512/tcp biff 512/udp comsat login 513/tcp who 513/udp whod shell 514/tcp cmd # no passwords used syslog 514/udp printer 515/tcp spooler # line printer spooler talk 517/udp ntalk 518/udp uucp 540/tcp uucpd # uucp daemon rsync 873/tcp # rsync mysql 3306/tcp # MySQL ircd 6667/tcp # Internet Relay Chat
