Re: v7.9beta [testing] is released!

the pppoe scan is broken since 7.8 (not working in 7.8beta3 nor 7.8) and it is still not working on 7.9.beta4 (just checked).

sniffer shows that the PPPoE discovery packet is sent the offer from PPPoE server is being received but the pppoe-client scan shows nothing.

Re: MPLS - what will you use it for?

I would use MPLS (if I had all the devices in network MPLS ready) to create VPN links for customers (i.e transparent interconnection between offices)

Scripts do not have 'screens' open, so you won't see it. It in certain cases will lock up the script since it cannot output. Always use :log and possibly create your own topic, or use 'script' or 'debug'. Run needs a script name also. Running by number doesn't always work. you should wrote: there i...

Re: How to act with log ?

Hi, Now the question. How can I read/filter the new lines out of the log. Or is there an other way it to control? it seems there is no way how to read Log content into a script variable (RouterOS 2.9.x). But it is possible to create log copy into a file. So you can read the file in a variable and t...

In 2.9 you can use the :log info (blah) command to print debug info to the log. That works better for me in 2.9. Hi, I know I can use :log command (I am using it for reporting). But I was used from 3 beta that :put works. In the 2.9.x it seems that the :put works only when used in sequence of comma...

:put used to debug print

Hi, I have started to write some script under RouterOS 3 Beta 7 and I am using :put to print some debug infos to console. Now I tried to run the script under 2.9.41 and the :put doesn't display anything on the screen (when used from a script). And the script seems to not run at all but no info/hint/...
