Internet daemons: portmap inetd.

NFS daemons: nfsd biod lockd statd.

The system is ready.

Booting might hang, stop (and print an error message) or go into an endless loop

at one of the positions 1 through 5. This might be caused by one of the problems

mentioned below. Check the indicated files and correct them if necessary or per-

form the indicated steps.

a) If booting stops at position ---1--- you might have one of the following prob-

lems:

•the bfsd is not running; go to 12.3.1.2, step 8

• the DISKLESS packages is not installed; see chapter 12.3.1.2, step 12

• the network is not set up correctly; check the configuration (see chapter

10.7.1)

If the problems above do not exist, please enter the following command in a

shell:

/sbin/arp -a

The output should contain a line like:

spect (149.236.99.99) at a.b.c.d.e.f [ether] on eth1

where a.b.c.d.e.f is a hexadecimal hardware ethernet address of the CCU. The

command arp -a displays all active connections, if there is no

spect entry

available, check the network configuration and the ethernet cable.

b) If booting stops at position ---2--- please try the following:

• push the CCU reset button

• type Ctrl-C to interrupt the boot process and enter:

>> setenv bootmode m

>> setenv bootmode c

• push the CCU reset button

c) If booting stops at position ---3--- one of the following problems exist:

• the CCU (hostname spect) is searched for on a nameserver first:

The search order is determined by hosts:

/etc/nsswitch.conf:

hosts: files dns nisplus

Make sure the first location to be searched is the local /etc/hosts file
