News for the 1.2.3 release: Fixed a server userauth bug with Denial of Service implications. An lshd compiled with IPv6 support didn't work on machines without IPv6. Fixed. Upgrading is recommended. The new version is available at http://www.lysator.liu.se/~nisse/archive/lsh-1.2.3.tar.gz ftp://ftp.lysator.liu.se/pub/security/lsh/lsh-1.2.3.tar.gz A patch file relative to lsh-1.2.2 is also available. It's quite big, mostly because I've upgraded to autoconf-2.50 in the meantime. Regards, /Niels
