it is better to use SSH, and as a bonus, there are more user friendly clients e.g. Xshell6, MobaXterm or even PuTTY.
Hope the script helps.
NOTE: Rather than use in-secure Telnet??
Also being a Windows user, you may find Mini WinSCP tutorial better than nano to create/edit scripts on the router.
Yes it will try other PING targets …. see below
Yes.
./ChkWAN.sh noaction once nowait
(ChkWAN.sh): 21479 v1.09 Monitoring WAN connection using 5 target PING hosts (ISP.GW.xxx.xxx ISP.DNS.xxx.xxx ISP.DNS.xxx.xxx 8 8.8.8.8 1.1.1.1) (Tries=3)./ChkWAN.sh -h
and rebooted my router when shortly after the connection dropped.
So your prime objective was achievedYesterday I changed the way the script is started, like this: 'sh /jffs/scripts/ChkWAN.sh ping=8.8.4.4,8.8.8.8,9.9.9.9,1.1.1.1'
And this morning, the script worked again
./ChkWAN.sh noaction nowait once fails=1 tries=1 ping=1.2.3.4,6.7.8.9,208.67.222.222,8.8.8.8So your prime objective was achieved
Hmm, can you try giving the script two PING addresses that are expected to fail and two that should work
e.g.
So ignoring the fact that v1.09 script reports the wrong PING IP when it failsCode:./ChkWAN.sh noaction nowait once fails=1 tries=1 ping=1.2.3.4,6.7.8.9,208.67.222.222,8.8.8.8
EDIT: v1.10 uploaded to correctly display the PING IP that fails.
if [ -z "$METHOD" ];thenif [ -z "$METHOD" ] || [ -n "$(echo "$METHOD" | grep "PING")" ];then # v1.10
if [ "$(echo $@ | grep -cw 'cron')" -gt 0 ];then
if [ -n "$(cru l | grep "$0")" ];then
CRON_ARGS=$(echo $@ | sed -e 's/\<cron\>//g') # Strip 'cron' from being passed to the cru entry
cru d Wan_Check
cru a Wan_Check "*/30 0 * * * /jffs/scripts/$0 $CRON_ARGS" # Every 30 mins on the half hour
CRONJOB=$(cru l | grep "$0")
Say "ChkWAN scheduled by cron"
echo -e "$CRONJOB"

Your wan-start script appears to try and prevent duplicate spawned processes, although I would probably use 'killall' ChkWAN.shIn the current v1.11 of the script https://github.com/MartineauUK/Chk-WAN/blob/d338debc4f114bd449233fe8d7e2261d70151baf/ChkWAN.sh#L412 it isn't a literal, but is a user configurable variable value if the default 30 secs is deemed inappropriate.
I mean its process (sleep 30) didn't appear in ps monitor when script stopped functioning.
RT-AC86U (ChkWAN.sh): 7971 Monitoring connection OK.....(Successful ping to '8.8.8.8'). Will check again in 30 secs
I'd like to know this as well. A complete beginner's step by step would be great.
I created a 'Dummies guide' Mini WinSCP tutorial How to copy/modify/execute a script which should get you started.
