Yesterday I was trying with tftpd, today i'm trying with atftp: I configured it by this HOW-TO: Im testing this on my local network, on the same computer.Also, Anubioz is giving you good advice in the other answer.

See the Wikipedia page for TFTP for more details on the protocol. Suggest trying again with a sniffer on the server, but look at all UDP traffic to the client, not just port 69. If your client has a firewall and you punched a hole to/from UDP 69, TFTP won't work.A Debian (Wheezy) PC provides both services in this example. I check make sure laptop pings and vice versa, etc.I wish :) 192.168.1.50 TFTP server // IP address of TFTP server 'serverip' 192.168.1.50 NFS server // IP address of NFS server 'nfs_ip' Note: The TFTP and NFS services do not need to be on the same physical server, or even the same operating system. that I try to upgrade except an IP address. Do you think that would interfere? There is nothing on port of switch, router, FW, etc.

I do have SNMPv3 configs and an ACL that applies to the SNMP config. The command should only contain the filename. The TFTP server requires the Root Directory to be pointed to be source/destination location.

Verify that a pathname is not specified when transferring files using the TFTP server using the command line.

Verify that the firewall allows TFTP requests through port 69.

There is no ACL applied to any port I connect my laptop to (tried mgmt. Refer to Configuring IP Access Lists for Cisco devices.

Verify that your router's access list includes your machine's IP address.

Yes I checked that and nothing is blocked.

On the TFTP server, go to File > Configure and verify that the Security and Advanced Security options are not blocking any requests from the router.

Verify that the TFTP server is running.
