It adds another option to the autoconf script (and changes src/include/pbs_config.in, src/resmom/requests.c) to allow use of scp version 1 for transfer of stdout and stderr files. This can be useful for sites that want to use scp with pure host-based RSA authentication (no passwords) but are running current versions of OpenSSH which do not support this with the default protocol, SSH Protocol Version 2. To apply this patch: # cd OpenPBS_2_3_16 # patch -p1 scpv1.patch Then, to use the new option, simple pass --with-scpv1 to configure when building the Makefiles.
