    Anyone have a script for monitoring cpu usuge?

    I just logged in and saw 1 core being maxed. Some rouge process has glitched and I have no idea how long it was pegged use a full cpu core. A script issuing a process kill, router reboot, or even email notification would be nice. Does anything like that exist or does it have to be created.

    Security Question about using eval inside script

    I know this question isn't really 100% Merlin-WRT related but I will be using the eval command within my QoS script in an attempt to pass parameters "ByReference" to a function. The answers I get will affect Merlin-WRT in a round-about way. I already looked this up on stack-exchange exchange...

    I have been poking around if there would be anyway to generate a file on the router from input on a page appended into the WebUI. Eg. I would like to create functionality so a user can add/delete/modify QoS rules within the WebUI. Rules can be generated within a table and upon hitting submit a...

    Is "Band Steering" Possible on our routers?

    Is it possible to have band steering, which would then allow same name 2.4 & 5ghz SSID's but have the router assist in kicking devices from 2.4ghz onto 5ghz. When I used to have the same name SSID, most clients would connect to 5ghz, remain on 5ghz until signal got low, fallback into 2.4ghz...

    Can you detect device disconnection?

    If you add a postlease into dnsmasq, you can do all sorts of cool stuff upon device connection. Is there some alternative to trigger a script upon device disconnection. (besides monitoring the client list for changes). (Yes I also know about power save/wifi sleep that will trigger many...

    Any way to clear command from terminal history (up/down arrow)

    Every time you execute a command it gets stored in two locations. 1) Stored in memory ( struct line_input_t -> char *history[MAX_HISTORY + 1]; ) 2) Stored in HISTFILE (/tmp/home/root/.ash_history) I have the following alias that I use often clr='clear && printf "\e[3J" ' The following...

    Is it possbile to attach qos rules to VPN interface traffic?

    So all VPN traffic goes through interface tun21. Inbound WAN traffic goes through interface eth0 Outbound WAN traffic goes through interface br0. Qos sets up TC rules for eth0 and br0 interfaces. Unfortunately this seems to mean that VPN clients are not bound by QOS rules and can drain...

    Anyone know the original TX power of Tmobile's RT-AC68 Firmware

    I have a Tmobile TM-AC1900 which is a rebranded RT-AC68. I changed the TMo firmware to asus (actually Merlin's fork) because I really wanted adaptive QOS and because we haven't gotten any security update for a long time. The problem is that while I have gained many features, I also lost some...
