Hello,
Just a small update for specific needs.
- Added configuration script so updates can happen only for the main script
System consists of 3 scripts: wrapper, config and actual update
script
so further updates can be done for a single script only without
needing
to edit the configuration every time (Tnx. Marc, LX1DUC).
- Only static routes from the main table will be processed, so dynamic ones
can co-exist without issues (Tnx. Adrian, YO8RXT)
Complete Mikrotik script for import:

Have fun,

Hello,
I rewritten the Mikrotik router script so it relies less on interactions
with RouterOS and processes mainly lists in memory.
So the speed significantly increased, an update check without changes on my
RB110AHx2 taking 4 seconds.
A full table and tunnel setup takes less than 1 min.
On a single core ARM, an update check takes less than 10 seconds.
The introduced delay will increase the runtime. Still on the RB1100 it takes
only 12 seconds for a check, and some 30 sec on the ARM, while the processor
load is quite small (15-20% on the RB1100).

Does somebody know a trick so that the postfix smtp server will accept a
particular illigal sender address.
(= ax25 hierarchical address of my bbs) so avoiding error 501.
I'm popping fbb and bpq for personal mail with fetchmail.

To mitigate this, I generally Deny by default - login/access to my AMPR hosts from 44.0.0.0/8 addresses or to the specific port/protocol (e.g. tcp/22 Denied by default from tun0, etc.)

Hi there
Is the AMPR.ORG (44.0.0.1) answer for ping request from 44 net address ?
for me it answer only from non 44 net ..
It has no tunnel route in the portal and therefore the packets not entering to the tunnel like any other 44 net
Should i have a specific route for it ?
2) from non amprnet this is what i get when i do ping to 44.0.0.1 is it correct or is it a problem ?

That is great Marius!
Always nice to see spectacular increases in performance in an existing program :-)
This should make it usable in practice.
Let's see how it works on Ronen's small router!
(maybe I do an experiment myself on a RB951G or RB750 when I can borrow it for this purpose)

Marius,
Do you have any explanation why the script requires a powerful router?
Is it just the general inefficiency of the MikroTik scripting language execution, is there some
operation called by the script that takes a lot of CPU, or is there a chance that by using a
more efficient algorithm (e.g. optimization of the case that nothing changes for an entry) a
lot of performance could be gained?
I ask this because your approach is of course the easiest to have everything integrated on a
single router, vs two alternatives that could be considered:
- run a Metarouter which does the multipoint IPIP tunneling and runs ampr-ripd
- run a Metarouter which runs the python scripts that update the config on the main router

Besides the generic method of using the Mangle table to apply a routing mark, there
is also the simpler method of using IP->Routes->Rules to directly select a routing
table based on a source address/network.
