How to login to CVS with extssh

I'm trying to setup Hudson to pull from a CVS repo, and need a .cvspass file to do that, and to generate .cvspass, I need to first login manually to CVS (AFAIK).

CVS server in question only seems to support extssh, and I can't figure out how to login into it. I tried something like this:

robert@robert-laptop:~/temp$ cvs -d  :extssh:USERNAME:PASSWORD@cvs.server.com:/path/to/project login
cvs login: CVSROOT password specification is only valid for
cvs login: pserver connection method.
cvs [login aborted]: Bad CVSROOT: `:extssh:USERNAME:PASSWORD@cvs.server.com:/path/to/project'.

I tried with and without password, and all other permutations I could think of, but nothing helped. Does som开发者_StackOverflow中文版eone know a proper way to do it?

UPDATE:

I managed to login and checkout with:

robert@robert-laptop:~/temp$ cvs -d :extssh:USERNAME@cvs.server.com:/path/to/repo co PROJECT_NAME

but .cvspass was not generated, which was the whole point. :(

The error says

cvs login: CVSROOT password specification is only valid for
cvs login: pserver connection method.

Since you do not use a pserver I would try

cvs -d  :extssh:USERNAME@cvs.server.com:/path/to/project login

It might be that you can't actually use CVS to store the password. Try to set up a password-less ssh connection. see http://ant.1045680.n5.nabble.com/Authenticating-cvs-extssh-w-o-getting-prompted-td1356537.html

From https://netpenthe.wordpress.com/2007/01/25/extssh-is-an-eclipse-only-cvs-connection-method/

The extssh connection method is unique to Eclipse CVS and doesn’t exist in the command-line CVS client. If you are using extssh to connect to a SSH2 repository and would like to use the command line client for some CVS operations you can configure the ext connection method to use extssh when inside Eclipse.

In other words... checkout the project in eclipse using the ext connection method and not extssh if you want to use the cvs command line client.
