Lately I decided to flash my Linksys wrt1200ac with dd-wrt as Linksys obviously dropped support for this nice hardware (no more firmware updates for a long time).
\nNot to mention that the vendor firmware is extremely basic (not to say limited…).<\/p>\n
Once I had flashed the device with the proper firmware, next step for me was to monitor bandwidth from my domotic\/monitoring box (jeedom).<\/p>\n
The most obvious track was snmp (dd-wrt feature) – Helas, the snmp daemon does not implement counter64 snmp values so this is useless.
\nNext step was to use some curl\/awk\/grep script like curl -u root:password http:\/\/192.168.1.250\/Status_Internet.asp, etc but the web pages heavily rely on javascript so here again, curl was a dead end.<\/p>\n
I finally resorted to remotely read values from the device nvram using a script around ssh : not the most elegant way, but the only one I could work out.<\/p>\n
The below will retrieve the day\/month\/year value from my Linksys wrt1200ac based on dd-wrt.
\nNote, I had to use ssh-keygen & ssh-copy-id to be able to ssh without having to provide a password.
\nOr alternatively, copy the root id_rsa.pub public key to the wrt authorized keys (tip: use sudo su on rpi to switch to your root account).<\/p>\n
