using tftp - can't get image, but can ping both ways
 

I have created a /tftpboot directory and chmod it to 777.
I have put an image 'uImage' on my Debian box under /tftpboot

In directory /etc/xinetd.d/ I have created file tftp:

Service tftp
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = /tftpboot
log_type = SYSLOG daemon info
log_on_failure = HOST
log_on _success = HOST
}

I restart tftp server with:

/etc/init.d/xinetd restart


Now I can ping the debian box from my pc and vice versa.
Now when I try to do an ftp:

tftp 192.168.2.211 GET uImage

I keep geting timeouts although uImage is on the debian box and it appears the tftp server is running.

Is the firewall blocking it?

Try on the server.
If that works then it is likely a firewall issue.

Started tftp. Typed connect 127.0.0.1 - seemed to connect ok.
The get uImage call got Transfer Timed out response.

Is the tftp server actually installed? The connect command does not actually create a connection.
What distribution are you running?

I'n running Debian.I think tftp is installed as I can start it with

>tftp
from the tftp prompt connect successfully and then the get fails with timeout.

cheers

Does /usr/sbin/in.tftpd exist?
tftp is the client, in.tftpd is the server. The connect command only saves the hostname it does not actually create a connection.

In a nutshell when xinetd detects a packet on port 69 it will launch the server tftpd. The client is not detecting anything from the server and so times out.

ok, thanks MichaelK,
getting further now.
the file in.tftpd now exists.

Now on the linux box I can do 'tftp'.
I can connect to 127.0.0.1
I do the get uImage. It waits for a while before coming back with a 'Transfer Timed out' message.
uImage is definitley there in /tftpboot. I also get the same error if I try and do a non existent file.

If I go to a dos prompt on another pc and do an ftp then connect to the linux box I get weird errors about:

Can't exec "/usr/sbin/pure-ftpd": No such file or directory at /usr/sbin/pure-ft
pd-wrapper line 174.
/usr/sbin/pure-ftpd-wrapper: Cannot exec /usr/sbin/pure-ftpd: No such file or di
rectory at /usr/sbin/pure-ftpd-wrapper line 174.
Connection closed by remote host.


Not sure these are relevant but it does mean maybe that I will have issues doing an ftp

Change the server_args to the following

Same problem. What I'm doing is
1. #tftp
2. >connect 127.0.0.1
3. >get uImage

anyone ? ftp not working on my pc

Lets get tftp working and then we can worry about ftp.
What are the permissions of /tftpboot and uImage?

firsly thanks for your help Michael,
permissions on /tftboot 777 and uImage is 644 ie it has read access for everyone.
Aside: I was unaware that ftp and tftp were different tools. I'm using tftp as you know.

Try turning on trace and verbose to help. These are tftp commands.
So
1. #tftp
2. >connect 127.0.0.1
3. >trace
4. >verbose
5. >get uImage
Post any debug infomation.

getting from 127.0.0.1:uimage to uimage
sent RRQ <file=uimage, mode=netascii>
sent RRQ <file=uimage, mode=netascii>
sent RRQ <file=uimage, mode=netascii>
sent RRQ <file=uimage, mode=netascii>
Transfer timed out

The client is not getting a response from the server. Make sure that xinetd is running. Is there any thing in the /etc/hosts.deny file?
