It seems I do not fully understand the discussion about ssh... When I manually make this command (what 'hg' does)...
ssh xxx.yyy.zzz "hg init test" ...the result is: bash: hg: Command not found... When I manually modify it... ssh xxx.yyy.zzz 'hg init test' ...the result is... !Adding key: proto=pass server=xxx.yyy.zzz service=ssh user=pavel password: ! ...and the remote repository is successfully created. Therefore I though the problem is wrong usage of " instead of ' in the mercurial port... Pavel
