Enable TFTP server

This article covers the following operating systems:

• RHEL (Red Hat Enterprise Linux) 5.3
• RHEL 6.2
• MacOS

RHEL 5.3

RHEL 5.3 based MDCs (Meda Data Controllers)

(from RHEL 5 documentation)

The TFTP config file should already be configured as follows (disables = no, server_args = <path>):

[root@sbf ~]# vim /etc/xinetd.d/tftp

#
# File /etc/xinetd.d/tftp
#
service tftp
{
...
...
       server_args             = -s /tftpboot
       disable                 = no
}

You must then restart xinetd for the new configuration to take effect:

[root@sbf ~]# chkconfig tftp on
[root@sbf ~]# service xinetd restart

To check if it is functioning (listening on the default port) use netstat:

[root@sbf ~]# netstat -nulp | grep 69
udp        0      0 0.0.0.0:69                  0.0.0.0:*                               22418/xinetd        
udp        0      0 0.0.0.0:69                  0.0.0.0:*                               22379/in.tftpd

To turn it back off:

[root@sbf ~]# chkconfig tftp off
[root@sbf ~]# service xinetd restart

To get files from the server using command line (Mac/Linux):

[user@client ~]$ tftp 10.0.0.2
tftp> get testFile.txt

 

RHEL 6.2

Notes for RHEL 6.x:

After installing the rpm the TFTP config file needs to be updated to enable the tftp.

The default path is /var/lib/tftpboot.

# rpm -ivh tftp-server-5.2-1.el6.rfx.x86_64.rpm

 

# vim /etc/xinetd.d/tftp

 disable = no

 

MacOS

TftpServer is a utility which helps you to utilize and configure the TFTP server shipped with the standard Mac OSX distribution.

Or use the native tftp server via CLI.

To start the tftp server on OS X 10.7 Lion:

sudo launchctl load -F /System/Library/LaunchDaemons/tftp.plist
sudo launchctl start com.apple.tftpd

The default tftp file path is /private/tftpboot but you can change that by editing /System/Library/LaunchDaemons/tftp.plist and re-starting with launchctl...

sudo launchctl restart com.apple.tftpd
