1. SRA telnet

The initial aim was to have a telnet client that would talk to a SSL server (i.e. be able to telnet www.netscape.com https). I also wanted to be able to use it as a replacement for the SRA telnet way of handling authentication.

When testing you will probably want something like this in your $HOME/.telnetrc file (where "orb" is replaced with the name of the host you are testing against).

 # /home/tjh/.telnetrc
 orb toggle options authdeb
 orb set autologin

The "key" is to have autologin set otherwise none of the "advanced" stuff (including SSL) is activated. Alternatively you can use the -K option to activate this stuff.

I haven't documented all this stuff yet as I've hacked the SRA stuff for SUNOS 5.x and IRIX 5.x support myself before I started on the SSL stuff. I'll sort it out soonish.

The rest of this is basically random notes to turn into something more useful later.

The first thing I did with SRA was to use the Eric Young DES library so a couple of little fiddles were needed to get this working correctly as a few "different" ideas exist in the various DES libraries that are floating around ... perhaps we can convince people to standardise on the Eric Young implementation as we use it quite effectively and it has been plugged back into the Bones version of Kerberos and it is used in SSLREF. 

1.1 libutil/ssl.c

Add this stuff ... most of the guts of the SSL to telnet/telnetd interface is in here. 

1.2 libutil/auth-proto.h

Add prototypes for the SSL interface in ssl.c 

1.3 libutil/auth.c

Add the ssl stuff into the list of "authenticators". 

1.4 telnet/commands.c

Add in ssl calls after connect(). 

1.5 telnet/externs.h

Declare the ssl vars that I use ... 

1.6 telnet/main.c

Add in processing of -z options which add

 -z ssl
 -z debug
 -z socks          # might as well!
 -z verify=INT
 -z cert=filename
 -z key=filename
 -z secure

 -z !socks
