Can't upload to tftp from Cisco catalyst switch

Again same story… I;m just beginner Linux users and having trouble with every task that I’m trying to use on linux rather than on Windows.
To copy/backup configuration and software bin files from cisco catalyst switch I have installed tftp server with yast installer
enabled TFTP firewall role , started service as described but having errors and no files are transferred to /svr/tftpboot
after some attempts I have removed -s and added -c but have no luck… Or maybe I don’t know sequence of arguments or something.

man tftpd

gives lots of options, but some things doesn’t make any seance to me.
its difficult to troubleshoot a problem because how UDP behaves.
Any help I will appreciate it.

Thank you.

When we talk about TFTP, then we can say that it is Trivial File transfer protocol. There is higher possibility that users are not capable to do some of the tasks like deleting, listing and renaming the files such as FTP and other advanced protocols but that is known as a selling point. You will observe that any system administrator or engineer will make it sure that the TFTP server is a vital tool when it comes to load firmware into network devices like routers and switches into some other usual task. We have a list of a few free TFTP Servers for Windows. Users can utilize these free tftp servers and make the most of it.

1- Solarwinds TFTP Server: This one comes along with a dual-threaded design that permits you to shift more than one files instantaneously and can deal file sizes of up to 4GB. It’s been observed that security is an issue when we talk about TFTP server. Nevertheless, it also tries to present a protection feature to the course through its IP restriction feature.

2- WinAgents Server: WinAgents always tries to lead some new structures, especially the usage of virtual folders because they are not found on the server but the user will have the imprint that they are. Yet, it’s a great thing for actual file organization that permits you to set out various dissimilar access rights to all folders so that it’s only reachable by your projected client.
