Is there any way I can get access to the source host (IP) of a
print job in a filter?
In LPRng you can filter the control file as it arrives on a machine
using the printcap entry
:incoming_control_filter=/.../filter_program
This allows the filter to correct problems in the information being
recieved by LPRng.
For example...
We use it to correct the username of printjobs comming from
Novell servers.
EG: Correct the entry P.user.group.domain to Puser
This in turn allows the user to delete his novell sumbitted print
jobs from a UNIX machine (using SAMEUSER permissions in lpd.perms).
We would like to extend this functionality further, referencing other
information sources, but to do so I need access the "originating
hostname" (REMOTEIP) of the printjob.
NOTE: this is NOT the "hostname" in the control file, (which Windows
2000 often have set incorrectly) but the host (or IP) that is passing
the printjob to the LPRng server. Lpd does have access to this
information as it uses it for "permission checking".
Is there any way I can access this info?
Even a small hack of the LPRng source code would be acceptable!
I have examined the environment passwd to the filter but no reference to
the source host is currently available, not even from a network
filehandle.
