Installing a TFTP Server on Red Hat 8.0
In this story we showed how to upgrade IOS on a Cisco using a TFTP server available from Cisco that ran on Windows. Well, just suppose you wanted to load a new IOS image from a TFTP server on a GNU/Linux box. We will use Red Hat 8.0 to provide a TFTP server.
First, install the RPM:
# rpm -i /usr/local/80rpms/tftp-server-0.29-3.i386.rpm
|
Edit /etc/xinetd.d/tftp:
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot
disable = no
per_source = 11
cps = 100 2
}
|
Restart xinetd:
[root@srv-1 cisco]# /etc/rc.d/init.d/xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
|
You can now put files in /tftpboot to download to your router. Change the folder if you wish. Beware of security issues. By default, anything in /tftpboot can be downloaded. You may wish to set the disable = yes when you aren't planning on using TFTP, and restart xinetd again.
