UNIX Host on the LAN

When troubleshooting a UNIX host on the LAN, make sure that:

• The host is booted and functioning properly.

• The host can communicate with other network nodes using

standard UNIX networking features and utilities.

• All Remote Access Concentrator software is installed

properly on the host. See the Software Installation Notes that

come with the Remote Access Concentrator software

release.

•Theerpcd daemon or tftp server (which loads the

operational image to the Remote Access Concentrator) is

running.

InTestMode,erpcdontheloadserverhostdisplaysbootprogressreports.

In Monitor Mode, the Remote Access Concentrator displays boot

progress reports. The Remote Access Concentrator displays its reports

ontheserviceportterminalthatinvokesitsMonitorMode;erpcddisplays

its reports on the UNIX terminal that invokes its Test Mode.

When running erpcd, all paths are relative to the /usr/spool/erpcd/bfs

directory for both boots and dumps. The /usr/spool/erpcd/bfs directory

is a default pathname and can be changed.

1. To place erpcd on the load server host into Test Mode, kill

the erpcd program (requires superuser privileges) and

restart it using the –D option:

# /usr/annex/erpcd –D5

2. Place the Remote Access Concentrator into Monitor Mode.

(This resets the Remote Access Concentrator, so warn users

before you do it.) Then, at the monitor prompt, enter:

monitor:: boot -v
