Greetings,
I have recently installed rssh on Solaris 10. After a lot a fiddling
round I have scp working as intended. However, sftp is a different story.
It seems that the Solaris 10 standard shipped version of sftp-server
accesses both /dev/null and /var/run/name_service_door on startup. When
starting up from a chroot'ed jail the absence of either of these will
cause failure.
A normal file in the jail will allow /dev/null problems to be
sidestepped, however I'm not sure what to try and do about
/var/run/name_service_door. A simple place holder does not seem to have
any effect, and I can't just copy the file as it is a door.
A snippet of a truss from a normal sftp-startup is attached to clarify.
On copying the sftp-server from a Solaris 9 installation I have now been
able to get sftp in a chroot environment working, however I would still
like to roll back to the standard binary if possible.
Any ideas?
Regards,
James Sewell
