This way is incorrect in two aspects. First, you'll have to compile libtelnet first: cd /usr/src/lib/libtelnet make obj && make depend && make cd /usr/src/usr.bin/telnet make obj && make depend && make && make install But second is that you'll get telnet w/o data encryption support, which isn't what you want (unless you have NOCRYPT=true in your /etc/make.conf). You can recompile telnet properly (in the typical case: no NOCRYPT and no MAKE_KERBEROS[45] either) using the following commands: cd /usr/src/secure/lib/libtelnet make obj && make depend && make cd /usr/src/secure/usr.bin/telnet make obj && make depend && make && make install However, I can overlook something more, so I'm giving no warranties at all...
