xinetd and the TFTP service

DevilWAH

A quick one

I have started up tftp with the following config on red-hat

[root@machine tftpboot]# more /etc/xinetd.d/tftp 
# default: off
# description: The tftp server serves files using the trivial file transfer \
#       protocol.  The tftp protocol is often used to boot diskless \
#       workstations, download configuration files to network-aware printers, \
#       and to start the installation process for some operating systems.
service tftp
{
        disable = no
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -c -s /tftpboot
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

If i try to copy a file from a remote device it fails with permissions errors unless I set the permissions on the tftpboot path to allow all to read and write.

it also creates the files in there with the user nobody.

-rw-rw-rw-   1 nobody nobody 13088 Jul 11 21:56 5_1.cfg-rw-rw-rw-   1 nobody nobody 13892 Jul 11 21:55 5_2.cfg
-rw-rw-rw-   1 nobody nobody 12548 Jul 11 21:55 5_3.cfg

I thought the idea of the user varible in the config was to set who the service runs as.

I don't want to leave the tftpboot path with all users able to read/write. Can any one tell me how to get TFTP to read and write as a specific user?

Never mind. I decided it was simpler to set permissions to only give read + write access to the user nobody, and deny all other access to the folder.
