tftp will not start.

[johnfitz]

I have setup nimol on a Fedora 9 machine. Nimol is installed and correctly configured and I have a client rs6000 (43p) declared in the dhcpd.conf file. all is running correctly and tftp is installed. I am monitoring /var/log/messages when I start the 43p and see the dhcp request come in and a reply with the correct address and subnet mask given as the reply. However tftp does not start and the 43p goes to SMS. Anyone know why tftp does not start please?

I think you'd be better off asking on an AIX forum.

Did you start xinetd?

tftp in Fedora is started by xinetd, you'll have to edit the following configuration located here /etc/xinetd.d/tftp and which looks like this

service tftp
{
   disable        = yes
   socket_type    = dgram
   wait           = yes
   user           = root
   server         = /usr/sbin/in.tftpd
   server_args    = -s /tftpboot
}

change disable=yes to disable=no and start xinetd

# service xinetd start

(I'm not on my Fedora box or anywhere near a linux box, I may be little off in configuration. Please make sure to use man and refer /usr/share/doc before you try this)

I have checked the tftp file and it is correct but still will not start any other ideas will be gratefully recieved.

Nope no other ideas.

I tried the following

# yum install tftp-server

My config file (in /etc/xinetd.d/tftp) looks like this

service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /var/lib/tftpboot
        disable                 = no
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

I then started xinetd

# service xinetd start

I then checked for the service with the following...

[root@localhost Download]# grep tftp /etc/services

And double checked by the following...

Beyond this I don't have any more ideas, perhaps it's be good to check the output of pstree.

I have checked the setup and have found the following:

[root@localhost Download]# ps aux |grep tftp
root 2770 0.0 0.0 10480 748 ? Ss 12:45 0:00 in.tftpd -s /var/lib/tftpboot
root 2787 0.0 0.0 83708 772 pts/0 R+ 12:47 0:00 grep tftp

When I run the ps aux the is no tftpd running although all the socket definition in /etc/services is correct. Once I start tftp and run the get command then I see in.tftpd in the process stack. Was it the same for you or does the daemon start once xinetd is started? Where is the install.log in /var/lib/tftpboot? On my machine this directory is empty! I tried defining the directory as /tftpboot as this is where Nimol puts the required files. I run the get command there and a file is returned! I also tried an arp -s statement to include the IP / MAC address of the server I am trying to install to.
