IRIS 3010, User Manual, Page: 90 / 145

The host distribution contains a copy of mexrc . After editing this file, you can
copy it to the IRIS with this command:
iftp mexrc /.mexrc
Installing Your Own Startup Program
The program that the IRIS 3010 runs after booting can be changed from wsiris
to a custom startup program. To do this, edit the file /bin/tesh and find the line:
set termemul = /bin/wsiris
Replace
/bin/wsiris
with the pathname of the program you want to have run.
If the IBM option is installed, t3279 is run instead of wsiris , and this line in
/bin/tesh must be changed:
set termemul = /bin/t3279
Replace
/bin/t3279
with the pathname of the program you want to have run.
If you add custom files to the root partition, you should duplicate them on the
backup partition so that they can be restored in case of boot failure. Before
copying these files, make sure that the IRIS boots and correctly runs your
startup program. The IRIS 3010 disk contains a script, /etc/rootcopy , that copies
the entire root partition to the backup partition. Run rootcopy , specifying the
argument ok :
rootcopy ok
5.3.3 XNS Configuration
Operation of the IRIS 3010 using XNS requires no configuration. The IRIS does
not need a hostname, since it initiates all connections, and the XNS protocol
does not require that both ends of a circuit have a name.
The terminal emulation program can be configured to initiate a connection to a
single host automatically every time it is started up. This procedure is
documented in Section 5.2.1.
5.3.4 TCP/IP Configuration
The TCP/IP option to the IRIS 3010 terminal is configured with the hostname
file /etc/sys_id , and the host tables /etc/hosts and /etc/hosts.equiv . The hostname
