TFTP / Solution for a linux server

[skyvana]

hi,

I want to use a TFTP server ( like this for Windows https://extremeportal.force.com/ExtrArticleDetail?an=000081258) but on Linux to upload a file to a switch. I tested several solutions (tftpd-hpa ...), but none works. 

Do you know a solutions who work?

Many thanks in advanced

Alex

Hi Alex,
your output from your first picture shows two process that are running on the tftp-ports (PID 3485 and 4146). Pls reboot the system an check if this is still so.
Pls. send the complete output of the command "systemctl status tftpd-hpa.service"
At the end you see, where the server is looking for files and where they will be stored.
For example:
root@test:/# systemctl status tftpd-hpa.service
● tftpd-hpa.service - LSB: HPA's tftp server
Loaded: loaded (/etc/init.d/tftpd-hpa; generated; vendor preset: enabled)
Active: active (running) since Mon 2019-05-20 14:45:48 CEST; 2 months 4 days ago
Docs: man:systemd-sysv-generator(8)
Tasks: 1 (limit: 4915)
CGroup: /system.slice/tftpd-hpa.service
└─874 /usr/sbin/in.tftpd --listen --user tftp --address 0.0.0.0:69 --ipv4 --create --secure /srv/tftp
(in my case its /srv/tftp)
Maybe you have to create this directory ?
To check the firewall settings try "ufw" or "iptables -L".

Axel

Hi Alex,
have you checked that the tftp-server is running (netstat -taup | grep tftpd-hpa)?
Have you checked that no firewall will block the traffic to/from the server?
What show the output of "tail -f /var/log/syslog" or the output of "tail -f /var/log/messages" when you try to receive a file from the server and what is the command you use at the switch to download the file?
Pls. give us a little bit more details.
regards,
Axel
