Subject:  - OpenBSD CVS updates:    - [channels.c]      repair x11-fwd    -
 [sshconnect.c]      fix passwd prompt for ssh2, less debugging output.    -
 [clientloop.c compat.c dsa.c kex.c sshd.c]      less debugging output    -
 [kex.c kex.h sshconnect.c sshd.c]      check for reasonable public DH values 
   - [README.openssh2 cipher.c cipher.h compat.c compat.h readconf.c]     
 [readconf.h servconf.c servconf.h ssh.c ssh.h sshconnect.c sshd.c]      add
 Cipher and Protocol options to ssh/sshd, e.g.:      ssh -o 'Protocol 1,2' if
 you prefer proto 1, ssh -o 'Ciphers      arcfour,3des-cbc'    - [sshd.c]     
 print 1.99 only if server supports both
