TFTP Usage

RouterOS General
1

I have some routers that I would like to be able to pull the config from for backup purposes.
These routers can write to a tftp server.

this has been helpful so far: http://wiki.mikrotik.com/wiki/TFTP

for the life of me I am unable to get them to write anything to my MK tftp

every attempt ends with “error reading data” in my mk logs

a print of my current tftp config is here:

IP-ADDRESSES REQ-FILENAME REAL-FILENAME ALLOW READ-ONLY HITS

0 0.0.0.0 * * yes no 0


as you can see, to start with I’m just trying to give wide open access so I can allow any device to upload to the mk tftp, once I can achieve this I’ll lock things down further.

Any thoughts on why this might be throwing that error?

also, when I connect to this from the router, it instantly throws cpu usage to 100% and then after 3 or 4 minutes the router becomes non responsive and a hard boot is required to get things going again.

any thoughts are

any thoughts from anyone using tftp at all?

Flags: X - disabled

IP-ADDRESSES REQ-FILENAME REAL-FILENAME ALLOW READ-ONLY HITS

0 192.168.20.0/24 yes no 1

Works for me without asterisks :slight_smile:

I have the same problems with upload to tftp on RB450 with ROS 3.23. (but on RB1000 with ROS 3.23no problem)
[rb450] ip tftp print detail
Flags: X - disabled
0 ip-addresses=10.0.0.0/8 req-filename=“” real-filename=“” allow=yes read-only=no hits=0
And then try upload file from 10.10.52.11 - I have many logs:
