Unix Study--Solaris 10 modifies host IP and host name

For the Solaris system, the host ip and hostname information are stored and managed through a series of configuration files (text), and the relevant configuration can be completed by modifying these configuration files through the editor.

1. Modify the host ip

1. Configure the hosts file

[root@solaris186:/] # cat / etc/hosts# Internet host table::1 localhost127.0.0.1 localhost192.168.8.11 solaris186 loghost [root@solaris186:/] # hostnamesolaris186 [root@solaris186:/] # vi / etc/hosts# Internet host table#::1 localhost127.0.0.1 localhost192.168.8.11 node1 loghost

2. View the network card information

[root@solaris186:/] # ifconfig-alo0: flags=2001000849 mtu 8232 index 1 inet 127.0.0.1 netmask ff000000 e1000g0: flags=1000843 mtu 1500 index 2 inet 192.168.8.11 netmask ffffff00 broadcast 192.168.255 ether 8:0:27:28:b1:8c

3. Modify hostname.e1000g0

[root@solaris186:/] # cat / etc/hostname.e1000g0 solaris186 [root@solaris186:/] # vi / etc/hostname.e1000g0 node1 [root@solaris186:/] # cat / etc/hostname.e1000g0 node1

4. Modify netmasks (subnet mask)

[root@solaris186:/] # cat / etc/netmasks## The netmasks file associates Internet Protocol (IP) address# masks with IP network numbers.# # network-number netmask## The term network-number refers to a number obtained from the Internet Network# Information Center.## Both the network-number and the netmasks are specified in# "decimal dot" notation, e.g:## 128.32.0.0 255.255.255.0192.168.8.0255.255.255.0

5. Modify the gateway configuration

[root@solaris186:/] # vi / etc/defaultrouter192.168.8.1 [root@solaris186:/] # cat / etc/defaultrouter192.168.8.1 [root@solaris186:/] # netstat-nrRouting Table: IPv4 Destination Gateway Flags Ref Use Interface- -192.168.8.0 192.168.11 U 11 e1000g0 224.0.0.0 192.168.11 U 10 e1000g0 127.0.0.1 127.0.0.1 UH 1 50 lo0

Summary:

Configuration files related to host ip

/ etc/hosts

/ etc/hostname.xxxx (network card name)

/ etc/netmaks

/ etc/defaultrouter

/ etc/inet/ipnodes

Second, modify the host name

1. Configure the hosts file

[root@solaris186:/] # cat / etc/hosts# Internet host table::1 localhost 127.0.0.1 localhost 192.168.8.11 node1 loghost

2. Modify hostname.e1000g0

[root@solaris186:/] # cat / etc/hostname.e1000g0 solaris186 [root@solaris186:/] # vi / etc/hostname.e1000g0 node1 [root@solaris186:/] # cat / etc/hostname.e1000g0 node1

3. Modify nodename

[root@solaris186:/] # cat / etc/nodenamesolaris186 [root@solaris186:/] # vi / etc/nodenamenode1 [root@solaris186:/] # cat / etc/nodenamenode1

4. View ipnodes

[root@solaris186:/] # cat / etc/inet/ipnodes # # Internet host table#::1 localhost 127.0.0.1 localhost 192.168.8.11 node1 loghost

Summary:

Configuration files related to hostname

/ etc/hosts

/ etc/hostname.xxxx (network card name)

/ etc/nodename

/ etc/inet/ipnodes
