I don't see any rc.tftpd or similar in /etc/rc.d. I want to use it to back up my CISCO router configs.

Check you /etc/inetd.conf , uncoment tha line below and restart the inetd service..

# tftp dgram udp wait nobody /usr/sbin/tcpd in.tftpd

to

tftp dgram udp wait nobody /usr/sbin/tcpd in.tftpd

Restart the inetd daemon.
/etc/rc.d/rc.inetd restart

This didn't work for me. When I try to tftp from my cisco router to my slack machine it times out. It's on my local lan so it can't be an IPTABLES rule. Suggestions?

Ok,

1 - Comment the tftp line in /etc/inetd.conf and restart the inetd daemon ( /etc/rc.d/rc.inetd restart )

2 - Make diretory whre these files will be stored
mkdir /tftpd

3 - Now running the in.ftpd daemon manualy

/usr/sbin/in.tftpd -c -l -v -s /tftp


4 - Edit /etc/rc.d/rc.local and put the below line:

if [ -x /usr/sbin/in.ftpd ]; then
/usr/sbin/in.tftpd -c -l -v -s /tftp
fi

I think for now will be working.

Now I have other i think the best way.


1 - Make directory for tftp

make /tftp

2 - Edit /etc/inetd.conf and change make some changes:

#tftp dgram udp wait nobody /usr/sbin/tcpd in.tftpd

to

tftp dgram udp wait root /usr/sbin/tcpd in.tftpd -c -v -s /tftp

I need to change user nobody to root and put more parameters for in.tftpd


3 - Restart the inetd daemon.



I realy think now we solved it and now we has two way to start in.tftpd.

This still isn't working for me. It still times out. I changed that line in inetd to "tftp dgram udp wait root /usr/sbin/tcpd in.tftpd -c -v -s /tftp", created that directory, restarted inetd, but got timeouts. A ps aux saw tftp running, but not tftpd running. And when I rebooted, tftp wasn't even running.

I made a mistake !!! you need change the permission of the /tftp to user and group nobody.
I make some tests using with lftp ip_address and i can send files and get files localy and remotely.

Still times out. There must be something funky going on because I cant even ping my slack machine from windows. From slack to windows I can ping fine, though.

You have configured tcp_wrappers? check your /etc/hosts.deny, if you have ALL:ALL in your hosts.deny you cannot login in tftpd.

If you have other linux make one test using lftp and try to login at ltftp server.

My hosts.allow/deny are empty.

I think that your CISCO router has lftp client and them try to access yout lftpd server or you can make some basics tests using the same lftpd server machine to connect like below:

1 - Put one file like /etc/hosts to /tftp

2 - try to login localy

cd /root
tftp localhost
get hosts
quit

3 - Check in /root if have hosts file.

I realy think you need some tests localy firts.

hi, this is my first post here but I wanted to offer a little insight to this problem because I have found these forums very helpful. I am using TFTP to boot diskless workstations (nodes) for a "beowulf" cluster and the problem I was having was with a Error PXE-T01 error File not Found. make sure your /etc/dhcpd.conf file is set to:
rather than Because you have already defined the base folder in Also make sure your permissions for user AND group are set to the same user you define in the command. (In my case above this was root) You can find this information by doing inside the /tftpboot folder

this fixed my problem when I rebooted. thanks for all the help!
