Reverse Telnet (RTEL)
TCP/IP Host Setup
7-12
When multiple print queues (possibly on more than one host) point to the same ETS queue, the hosts will
provide local queueing, but you may still have multiple jobs attempting to access the ETS. In this case, the
ETS will provide queueing among the hosts. Jobs from multiple hosts are handled in order, regardless of
size or priority. This may explain why a particular host’s queue seems to stop for an extended time.
The Show Queue display on the ETS will show the order of jobs pending on the ETS. The host’s lp or lpr
utilities must be used to show jobs queued by the host.
7.3.4 Setting up the RTEL Backend Filter
RTEL backend filters are designed to work with BSD, SYSV, and AIX type printing subsystems. The
backend filter simply accepts data from the queue manager and moves that data over the network to the
terminal/print server.
To set up the RTEL backend filter,
1
Become superuser.
2
Install the RTEL software according to Figure 7-13.
3
Execute the mkprt script.
The following example illustrates the process on a BSD-type system. When it is completed, the queue (hp4)
should be able to process requests.
