Unix for Advanced Users - Light SysAdmin Tasks - Networking - knowing which files to edit to set up or change IP#, gateway, broadcast, netmask, and DNS

17. Light SysAdmin Tasks

Clearly, this is highly vendor specific. Here are the details for each vendor:

HP-UX 10.20:

/etc/rc.config.d/netconf sets your hostname, IP address, netmask, gateway (or default route),
/etc/resolv.conf specifies DNS servers.

IRIX 6.x:

/etc/hosts specified the IP number and hostname.
/etc/sys_id contains the FQDN of the host.
/etc/config/ifconfig-1.options specified netmask.
/etc/config/static-route.options specifies the default route or gateway:
```
$ROUTE $QUIET add net default 129.79.28.254
```
On SGIs an additional line is added to /etc/resolv.conf between the domain and search lines to specify the order in which DNS and hosts file are consulted (it performs the same function that /etc/nsswitch.conf does for other Unixes):
```
hostresorder     local bind
```

Red Hat Linux:

/etc/sysconfig/network will contain entries for your host name, domain name, and gateway address (default router).
/etc/sysconfig/network-scripts/ifcfg-eth0 will contain entries for your IP number, netmask, and broadcast address.
/etc/hosts you will find your hostname and IP number as well.
/etc/nsswitch.conf specified the order in which DNS and hosts file are consulted.
/etc/resolv.conf will contain data about your domain, nameserver, and search paths.

Solaris 2.x:

/etc/hosts specifies the host name and the IP number.
/etc/net/*/hosts specify the hostname.
/etc/hostname.le0 specifies hostname that matches /etc/hosts for the ethernet interface le0. (You may have other interfaces, such as hme0, etc.)
/etc/netmasks specifies netmasks for the entire network.
/etc/defaultrouter specifies the default router.
/etc/nsswitch.conf allows the specification of the order in which DNS and hosts files are consulted. /etc/resolv.conf sets up DNS servers.
