NIS = Network Information Service, YP = Yellow Pages

1. Add domain to file /etc/sysconfig/network

NISDOMAIN=mydomain

2. Add IP to NIS server to /etc/yp.conf file

domain mydomain server 192.168.2.25

3. Start it

/etc/init.d/ypbind start

wget –recursive -x -l 0 -e robots=off –wait 1 \
-U Mozilla –no-parent –user=user –password=password \

The /etc/sysconfig/network file contains the
HOSTNAME and the GATEWAY.

The /etc/sysconfig/network-scripts/ifcfg-eth0 file contains the
IPADDRess, NETMASK and BROADCAST addresses.

On an embedded board (TS7260) I was testing, it turned out
that the MAC address of the network adapter was all FFs.

As a result, I was not able to network to the board at all.

Here is how to set the MAC address:

$ ifconfig eth0 down
$ ifconfig eth0 hw ether 00:80:48:BA:d1:20
$ ifconfig eth0 up

• — tcpdump
  — Example:
  tcpdump -enqti eth0 \( arp or icmp \)

  -e Print the link-level header on each dump line.

  -n Don’t convert addresses (i.e., host addresses, port numbers, etc.) to names.

  -q Quick (quiet?) output. Print less protocol information so output lines are shorter.

  -t Don’t print a timestamp on each dump line.

  -i Listen on interface.

• — ping
• — netstat -lptun

  l = listening sockets (-a for all), p = show program (app), t = tcp, u = unix, n = numeric address.

• — arp
  — Example:
  arp -ne
• — route
• — traceroute
