First, add the two following lines to your CONFIG.SYS and reboot. If you don't have CVS installed in D:\SW\CVS, change the first line appropriately. If OpenSSH is not installed in D:\SW\OpenSSH, change the second line.

SET CVS_RSH=D:\SW\CVS\bin\CallSSHRight.CMD
SET PATHTOSSH=D:\SW\OpenSSH\ssh.exe

Then, create the file D:\SW\CVS\bin\CallSSHRight.CMD with the following content:

@echo off
%PATHTOSSH% %1 %3 %4 %5

Anonymous Checkout and Export. 

Please issue the following commands :

cvs -z9 -d:ext:anoncvs@egothor.org:/cvsroot export -r HEAD egothor

or

cvs -z9 -d:ext:anoncvs@egothor.org:/cvsroot co egothor

When prompted for the password, please enter anoncvs and press Enter.
