Module: Sysconfig_Route
|
||
|
|
Parses /etc/sysconfig/network-scripts/route-${device}

About: Reference
|
||
|
|
This lens allows manipulation of *one* IPv4 variant of the
|
||
|
|
/etc/sysconfig/network-scripts/route-${device} script found in RHEL5+, CentOS5+
|
||
|
|
and Fedora.
|
||
|
|
|
||
|
|
The variant handled consists of lines like
|
||
|
|
"destination_subnet/cidr via router_ip", e.g.,
|
||
|
|
"10.132.11.0/24 via 10.10.2.1"
|
||
|
|
|
||
|
|
There are other variants; if you use them, please enhance this lens.
|
||
|
|
|
||
|
|
The natural key would be "10.132.11.0/24" with value "10.10.2.1", but since
|
||
|
|
augeas cannot deal with slashes in the key value, I reverse them, so that the
|
||
|
|
key is "10.10.2.1[1]" (and "10.10.2.1[2]"... if multiple subnets are reachable
|
||
|
|
via that router).

Sample usage of this lens in augtool
|

> set /files/etc/sysconfig/network-scripts/route-eth0/10.10.2.1[1] 172.16.254.0/24
|
||
|
|
* List all the subnets reachable by a router reachable on eth0 subnet
|
||
|
|
> match /files/etc/sysconfig/network-scripts/route-eth0/10.10.2.1
