OpenSSH, FTP and other Unix utilities
OpenSSH. This is the replacement for telnet. It is amazing how many old Unix utilities like ftp and telnet are still being used. Heck, I learned how to use it in 1975 when I was a teenager. I guess that dates me. At least, some things aren't obsolete. I'm switching to ssh since it is more secure than telnet and here is the top utility there.
SmartFTP. This is the best FTP utility that I've found. Thanks to John Ludwig for pointing out. The best thing about it is that there are queues of FTP downloads and the downloads are restartable. I've also tryed WS_FTP and it is good, but SmartFTP is great.
