6.11. Running Quagga Daemons from the Command Line

Problem

Do you have to edit configuration files? Can't you write them from the Quagga command line, or do commands on the fly?

Solution

Yes, you may do all of those things from both vtysh and telnet. The commands are exactly the same on the command line as they are in configuration files, so you can write all of your configurations from the command line if you wish. Here is a simple example for zebra.conf:

	carla@xena:~$ telnet localhost 2601
	router1> enable
	router1> write terminal
	router1# configure terminal
	router1(config)# hostname zebra2
	zebra2(config)# password zebra
	zebra2(config)# enable password zebra
	zebra2(config)# log file /var/log/quagga/zebra.log
	zebra2(config)# write file
	Configuration saved to /etc/quagga/zebra.confzebra2(config)# write terminal

This does not completely overwrite your existing configuration file. It changes existing options and adds new ones, but does not delete any. write terminal shows your current configuration, so if you wish to delete existing options, you can first see what they are, then remove them with the appropriate no command:

	zebra2(config)# write terminal Current configuration: ! hostname zebra2 password zebra enable password zebra log file /var/log/quagga/zebra.log ! interface eth0 ipv6 nd suppress-ra ! interface eth1 ipv6 nd suppress-ra ! interface lo ! interface sit0 ipv6 nd suppress-ra ! access-list localhost permit 127.0.0.1/32 access-list localhost permit 192.168.1.0/24 access-list ...
