Issue

• Is it possible to configure tftp for normal user credentials?
• In tftpboot configuration, it's mentioned to run tftp by root.

[root@localhost ~]# egrep -v "^$|^#" /etc/xinetd.d/tftp
service tftp
{
    disable = no
    socket_type     = dgram
    protocol        = udp
    wait            = yes
    user            = root                 <=============== user is root
    server          = /usr/sbin/in.tftpd
    server_args     = -s /var/lib/tftpboot
    per_source      = 11
    cps         = 100 2
    flags           = IPv4
}

• The following configuration is not working and showing errors.

[root@localhost ~]# egrep -v "^$|^#" /etc/xinetd.d/tftp
service tftp
{
    disable = no
    socket_type     = dgram
    protocol        = udp
    wait            = yes
    user            = testuser                 <=============== user is testuser, not root
    server          = /usr/sbin/in.tftpd
    server_args     = -s /var/lib/tftpboot
    per_source      = 11
    cps         = 100 2
    flags           = IPv4
}

• The errors are as follows. From Client end.

[root@localhost ~]# tftp 192.168.0.185
tftp> get kernel-2.6.32-431.29.2.el6.x86_64.rpm
Transfer timed out.
