[SOLVED] TFTP error: "Only absolute filenames allowed"
[SOLVED] TFTP error: "Only absolute filenames allowed"
Workaround
I'm not sure what was going wrong with what I was doing initially, but, thanks to @[email protected], as suggested, I disabled the tftp server system service, and, instead, started it with the following command:
sudo in.tftpd -L /srv/tftp --verbose --permissive -s
and it then flashed successfully.
Original Post
I'm trying to flash firmware to a router (Archer C7) using TFTP, but, when the router makes the request for the firmware file over TFTP, the TFTP server responds with the following error
Error code: Access violation (2)
Error message: Only absolute filenames allowed
This is the config for tftpd in /etc/conf.d/tftpd:
TFTP_OPTIONS="-s"
TFTP_DIRECTORY="/srv/tftp"
TFTP_USERNAME="tftp"
TFTP_ADDRESS="192.168.0.66:69"
I have the firmware file in /srv/tftp, and both the firmware file, and /srv/tftp have chmod 777 permissions.
The TFTP server is running on Archlinux, and is installed as tftp-hpa from the arch repos.
If I test as a client, I can get it to download if I specify the full (absolute) path to the file /srv/tftp/filename, so it seems that the config isn't pointing the server to /srv/tftp as the relative path... How would I go about fixing that?
You're viewing a single thread.
Is it asking you to specify /srv/tftp/filename even though you're in the directory?
That's what seems to be happening. The directory is specified in the config file, but it appears that it is being ignored? It should be able to accept a non-absolute path, and then map relative to the specified directory in the config file.
It probably won't help, but have you tried mapping tftp to / and going to the absolute path from there?
I set
TFTP_DIRECTORY="/", and then restarted the service, but, unfortunately, it didn't work.
