TFTP Issues

Distro Discussion & Help
1

Hi There,

I am running my first install of the FreePBX Distro and I am having some problems with the TFTP Server.

When using grep tftp /var/log/messages

I see

I tried to re-install the tfpt server but it says it’s already installed.

From the advice of another forum I ran this command:

192.168.1.124 is the ip of my install

When I run netstat --proto=inet,inet6 -pnl

I see:

I am not a Linux person, so I might be causing more harm than good. I just want to get my TFTP server back operational.

Thanks

Ok, first I fixed your code tags, you can use HTML or BBCODE, not BBCODE in HTML tags. BBCODE uses brackets not carats. Notice how your columns are all straight and readable? Before it was near impossible to read the netstat.

I do appreciate the effort so you get a more detailed response (effort is greatly awarded!)

/usr/sbin/in.tftpd -l -a 192.168.1.124:69 -c -s /tftpboot

First run this command to see if tftp is running:

[root@maieast ~]# ps aux | grep -i tftp
root      8068  0.0  0.0   4004   660 pts/0    R+   21:10   0:00 grep -i tftp
root     24810  0.0  0.0   2204   640 ?        Ss   Oct04   0:06 in.tftpd -v -s /tftpboot
[root@maieast ~]#

Then run this command to show me your tftp config.

root@maieast ~]# cat /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
{
 socket_type   = dgram
 protocol   = udp
 wait    = yes
 user    = root
 server   = /usr/sbin/in.tftpd
 server_args   =  -v -s /tftpboot
 disable    = no
 per_source  = 11
 cps     = 100 2
 flags    = IPv4
}

Please post output off both and we will go to next step.

OK, when I run: ps aux | grep -i tftp

I see:


root      9291  0.0  0.0  61208   816 pts/0    S+   19:39   0:00 grep -i tftp

When I run cat /etc/xinetd.d/tftp

I see:

# 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             = -s /tftpboot
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

Ok, so we know it’s not running.

Run ‘service xinedt stop’ ‘service xinitd start’ ‘tail /var/log/messages’ and send the output.

Thanks for reviewing things for me.

[root@localhost ~]# service xinedt stop

gives me:

xinedt: unrecognized service

[root@localhost ~]# service xinitd start

gives me:

xinitd: unrecognized service

[root@localhost ~]# tail /var/log/messages

gives me:

Oct 14 04:02:08 localhost syslogd 1.4.1: restart.

Scott had a type

To restart the service type

/etc/init.d/xinetd restart

7

/etc/init.d/xinetd restart

gives me:

[root@localhost ~]# /etc/init.d/xinetd restart
Stopping xinetd:                                           [  OK  ]
Starting xinetd:                                           [  OK  ]

tail /var/log/messages

now gives me:

Oct 14 04:02:08 localhost syslogd 1.4.1: restart.
Oct 14 15:44:38 localhost xinetd[3820]: Exiting...

Ok, how about running the ps aux | grep -i tftp again? Is it running?

I get the feeling you are just typing commands and not understanding any of this.

You are following my steps literally and not taking any leaps.

Anyway, edit your cat /etc/xinetd.d/tftp, look at mine, take out the disable line and add the verbosity flag (the -v) to the start arguments so we get more info than the messages.

Restart the service again (you can do Tony’s way or ‘service xinetd restart’ (both work) and then tail out your system messages file.

On the off chance it’s disable in the config file do a ‘cat /etc/xinetd.conf’

i solved my problem with
a addition to the dhcpd.conf

subnet 192.168.71.0 netmask 255.255.255.0 {
next-server 192.168.71.1;
option routers 192.168.71.1;
—> option tftp-server-name “192.168.71.1”; <---------
option subnet-mask 255.255.255.0;

Hi
i am using freePbx and now i got a number from service provider they configure this number in Alcatel-Lucent device with some IP and TFTP that i can see in Alcatel-Lucent device can i configure this alcatel setting in my pbx to receive all in pbx. i have ip,subnet.tftpserver.port, so plz let me know what is the method to connect it.
