Strange behavior with 2.5.1 installed over 2.3.0

[Alexander Ivanchev]

Hello.

I've recently installed OpenSSH 2.5.1p1 over a working installation of
2.3.0p1 (both SSH1 and SSH2) and oddly enough I lost SSH2 support. The
banner string states SSH-1.5-OpenSSH_2.5.1p1, which needless to say limits
me to SSH1... I haven't yet bothered to check any conf files, but since I
haven't really made any changes this behavior seems strange to me... Anyway,
hope I'm not wasting anybody's time,

 Regards
