countdown to reboot....

RouterOS Scripting
1

Hi,

I have setup the CPE’s wireless connect list but i discovered when i run winbox remotely and try from winbox terminal
/interface wireless scan wlan1
to scan it disconnects the link (as normal ) but does not restore previous AP association unlike running terminal locally it does ?

The reason i want to scan CPE’s wireless remotely is as more AP’s are put on the network, i may need to change the connect list order, I don’t want to scan locally each CPE
so if could have a script that would
(1) countdown - say 2mins to reboot
(2) included or manually /interface wireless scan wlan1
(2) save the scan so on reboot it could be checked which AP connect list order should be used

I can’t say I’ve tried this, but the below might work as a script. You can’t initiate a reboot in two minutes and then scan - you’ll have to scan first, and then reboot:

/interface wireless scan wlan1 file=scanOutput.txt
/system reboot

Does that help at all?

[XXXXX_XXXX19@XXXXX_test19] > /interface wireless scan wlan1 file=scanOutput.txt
bad argument name file (line 1 column 32)
[XXXXX_XXXX19@XXXXX_test19]] > /system reboot
Reboot, yes? [y/N]:

looks like it does not want to generate file as f (file=scanOutput.txt) is highlighted

thanks for advice

Then you can’t save the output of a scan to file. You’d have to either use the API or something like expect via SSH/Telnet to remotely run the commands.

Look into history


there is a way how to scan on interface you are connected to… using SSH

set duration to low value (10s for example)

nature of SSH is it willnot drop connection very quicly and scan result will be printed out to console after scan and reconnection.

for example this is AP to wchich i am connected as a station (laptop)

admin@10.78.9.2's password:

Thanks but i note you were using RouterOS 5.0beta4, when i try using ssh scan on version 3.30 I have to use code:
[Client_test19@Client_test19] /interface wireless> scan
– Item number
duration –
freeze-frame-interval – Interval on how often to perform the scanning

[Client_test19@Client_test19] /interface wireless> scan wlan1 duration=10s

Which disconnects the Wlan connection and PPPoE reassigns a new ip address to CPE client and scan is lost, maybe i doing something wrong as usual ?

7

If you at reconnect getting new IP address from your ppp session, that TCP session will not be kept.

8

That is my problem, if i could save a scan then the next step is ok, but looks like catch21 so far?

9

No you cannot save it to file unfortunately, its a feature not bug, maybe a feature wish-list could be a good idea to use it.

EDIT:

Well, you can you another Interface, but in this solution cost is involved (additional hardware requirements)

10

what about establishing a new tunnel (pptp, etc) with static private addresses? %)

11

Tried pptp but once again when wireless connectivity is lost so is the result of scan when i try to execute
[Client_test19@Client_test19] /interface wireless> scan wlan1 duration=10s

As mentioned if i could only save the scan?

Another Q is should pptp connection be displayed in the ppp active connections, see picture
as Client_test19 which i was using at test is missing from ppp active list but reappears when i select pppoe ?
