Tftp file not found

Hello everyone,

I am currently using the latest release of PBX in a Flash. I would post on their forums but no one seems to want to activate my account over there…

Anyways, my office has been using Bria 3 and we just got in a few Polycom 301’s. I have been trying to configure them and I am going crazy trying to get them to work. The part I am stuck on is with tftp.

It seems that the tftp server is up and running but I can’t access it. I can’t access it from my computer or the server. Whenever I do “tftp -v 127.0.0.1 (or 192.168.1.111) -c get test.txt” I get:

Connected to 192.168.1.111 (192.168.1.111), port 69
getting from 192.168.1.111:test.txt to test.txt [netascii]
Error code 1: File not found

The file is there, but “apparently” it isn’t. I have been looking for similar instances of this and I just can’t find anything helpful.

Does anyone know what is wrong?

Thank you for your time,

-Alonzo

Anything in /var/log/messages on the server that would indicate the problem? Perhaps permissions on the file?

This is what I get:

It seems that tftp is talking to my laptop, but I still get the “File can’t be found” I even made the file with 777 permissions. I get the same results when I try it from the server.

Thank you for responding.

I am up to trying what ever you suggest. I have made no additions to the PIAF distro other than installing the tftp client package to diagnose the problem I am having.

I appreciate your help immensely.

Does /tftpboot exist? IS the file there? What are the permissions of the directory and file.

/tftpboot exists with the following permissions:

drwxrwxrwx 7 root asterisk 4096 Feb 1 19:12 tftpboot

This is what is inside it:

[email protected]:/tftpboot $ ls -la

I added the test.txt and I have been trying to download, but it keeps saying it does not exist…

Are there any files in the logs directory.

What does the the following command show?

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 = -s /tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4

Also - update server_args line to include -v

    server_args             = -v -s /tftpboot

Not sure how you restart it though to take the new options, I don’t remember exactly. This will show more of what the server is doing while processing the files. That is why my messages log is showing file names, etc.

There are 2 files in the /tftpboot/logs directory:

[email protected]:/tftpboot/logs $ ls
0004f205cf2f-app.log 0004f205cf2f-boot.log
[email protected]:/tftpboot/logs $ cat 0004f205cf2f-app.log
[email protected]:/tftpboot/logs $ cat 0004f205cf2f-boot.log

They are empty, however. Those files reflect the phone I am trying to setup.

As for xinetd.d/tftp:


[email protected]:/tftpboot/logs $ 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
{
        disable = no
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /var/lib/tftpboot
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

I made sure to check that disable = no was set…

I added the -v though. Is there anything I should do now?

Here is the problem,

This

server_args = -s /var/lib/tftpboot

should be this

server_args = -s /tftpboot

Well, that did the trick… Do you have any clue why it would be like that? I didn’t change anything to the config file, at least that I know of. I’ve been making as few adjustments to this server as possible because I want it to remain stable, ha ha.

Thank you for that. A BIG thank you to everyone who gave their advice, I REALLY appreciate it.

Edit

The funny thing is that I saw /var/lib/tftpboot referenced in other threads as if that is how it is supposed to be. Like in this one: http://pbxinaflash.com/forum/showpost.php?p=75497&postcount=30

I actually can’t wait to get to work tomorrow and try this now, ha ha.

Your welcome.

I could not tell you why it is set that way on PBX in a flash. Maybe the post was a typo.

I am happy to hear it is working for you.

Glad you got it working! Looks like somewhere along the line things got out of sync on file locations with the distro you were using. Perhaps a OS bug fix changed a file location or it simply was just never tested.

I have learned to expect that with the distros. They make it really easy to get going, but if you end up with a problem either expect to roll up your sleeves or pay for support. Compared to what you would pay for an out of the box phone system it is still a great value and a fun technical challenge :slight_smile: They systems they have created are really very complex!
