* Very big makeover in the way telnet, telnetd and libtelnet are built.Mark Murray2003-07-1613-7703/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, there were two copies of telnet; a non-crypto version that lived in the usual places, and a crypto version that lived in crypto/telnet/. The latter was built in a broken manner somewhat akin to other "contribified" sources. This meant that there were 4 telnets competing with each other at build time - KerberosIV, Kerberos5, plain-old-secure and base. KerberosIV is no longer in the running, but the other three took it in turns to jump all over each other during a "make buildworld". As the crypto issue has been clarified, and crypto _calls_ are not a problem, crypto/telnet has been repo-copied to contrib/telnet, and with this commit, all telnets are now "contribified". The contrib path was chosen to not destroy history in the repository, and differs from other contrib/ entries in that it may be worked on as "normal" BSD code. There is no dangerous crypto in these sources, only a very weak system less strong than enigma(1). Kerberos5 telnet and Secure telnet are now selected by using the usual macros in /etc/make.conf, and the build process is unsurprising and less treacherous. Notes: svn path=/head/; revision=117675

| | | | | | | | | | | | | | | | to do what they are supposed to: under some circumstances output data would be truncated, or the buffer would not actually be flushed (possibly leading to overflows when the caller assumes the operation succeeded). Change the semantics so that these functions ensure they complete the operation before returning.

* Add SRA authentication to src/crypto/telnet.Nick Sayer1999-08-161-0/+24
| | | | | | | | | | | | | | | | | | | | | | | SRA does a Diffie-Hellmen exchange and then DES-encrypts the authentication data. If the authentication is successful, it also sets up a session key for DES encryption. SRA was originally developed at Texas A&M University. This code is probably export restricted (despite the fact that I originally found it at a University in Germany). SRA is not perfect. It is vulnerable to monkey-in-the-middle attacks and does not use tremendously large DH constants (and thus an individual exchange probably could be factored in a few days on modern CPU horsepower). It does not, however, require any changes in user or administrative behavior and foils session hijacking and sniffing. The goal of this commit is that telnet and telnetd end up in the DES distribution and that therefore an encrypted session telnet becomes standard issue for FreeBSD.

* PR: bin/771 and bin/1037 are resolved by this changeFrank Durda IV1997-10-081-0/+16
| | | | | | | | | | | | | | | | | | | This change changes the default handling of linemode so that older and/or stupider telnet clients can still get wakeup characters like <ESC> and <CTRL>D to work correctly multiple times on the same line, as in csh "set filec" operations. It also causes CR and LF characters to be read by apps in certain terminal modes consistently, as opposed to returning CR sometimes and LF sometimes, which broke existing apps. The change was shown to fix the problem demonstrated in the FreeBSD telnet client, along with the telnet client in Solaris, SCO, Windows '95 & NT, DEC OSF, NCSA, and others. A similar change was incorporated in the non-crypto version of telnetd. This resolves bin/771 and bin/1037. Notes: svn path=/head/; revision=30212
