Asuswrt-Merlin 378.56 Beta 2 is out

[daxy]

I'm still running beta 1 on my RT-AC87U, yet I believe this isn't beta 1 specific.

As of last night the filesystem seems full. I can't login anymore and syslog is full with:
Oct 23 08:57:45 192.168.1.1 dnsmasq-dhcp[438]: failed to write /var/lib/misc/dnsmasq.leases: No space left on device (retry in 9s)

Also I can't SSH into it anymore:
user@host:/var/log$ ssh admin@192.168.1.1
ssh_exchange_identification: Connection closed by remote host

As I'm not at home I can't login via the GUI yet and the VPN server doesn't work either.
Download Manager is off, minidlna is off, only timemachine backups are on. I'll need to check what's filling the space but without access it will be difficult

Anyone else perhaps seen this file system full?

Anyone else perhaps seen this file system full?

Ops, checked my two systems, one in router-mode and one in access-point mode and both showed this (2 x AC66U/beta2) :

Upgraded from 55 -> 56beta2. No factory reset.

hi @thelonelycoder , I got an N66U with .55 Merlin, but Im trying to do this, but changing the paths to my own, .. I placed the dnsmasq.postconf in the jffs/scripts, made it executable, and it just says when I try to run it lin 9: cant creat : nonexistent directory
Thanks

Thanks Merlin, it works now as advertised! I am running the beta-2 again.

For the benefit of others here's my /jffs/scripts/dnsmasq.postconf

#!/bin/sh
CONFIG=$1
source /usr/sbin/helper.sh

if [ -d "/mnt/sda1" ]; then
        pc_append "
log-facility=/mnt/sda1/dnsmasq.log" $CONFIG
        pc_append "log-async" $CONFIG
        pc_append "log-queries" $CONFIG
fi

Note the line break in pc_append "log-facility=/mnt/sda1/dnsmasq.log" $CONFIG
This is to force a new line in the dnsmasq.conf. As I have a commented out entry at the end of dnsmasq.conf.add it would append log-facility=/mnt/sda1/dnsmasq.log to that line.

With the line break it works just fine.

Hi is it possible to create an selectable option to remove the NULL/npch from the logging, is filling up the whole log and syslog without any information. I read here that is is probably from a protected code, as it can't be remove we can at least try to suppress it?

Any thoughts?

This is located in RAM. If that location is full, it means your router is out of RAM.

That debug output comes from a closed source component, it's totally outside of my control.

So it cant be removed from the logs?

No. The logging call is made from within the component.

Looks like / (root fs) is full. Or am I reading it wrong...

 

[joegreat]

Yes, the / (root fs) is full - always - as it contains the firmware of the router and you cannot write to it - unless you flash a new firmware...

 

[shooter40sw]

Is there a way to test this without booting? dont want to mess up, my USB drive has a name, if I use it if I execute the dnsmasq.postconf it gives me an error, and if I use the sda1 it does not, but I check the file and there is nothing added to the dnsmasq.conf file, please help
thanks

Think I finally made it after multiples errors. The only thing that worked for me was $'\n'. I'm a complete noob. Thanks RMerlin and thelonelycoder. Note that logging is disabled on purpose for now.

#!/bin/sh
CONFIG=$1
source /usr/sbin/helper.sh

if [ -d "/mnt/sda1" ]; then
        pc_append $'\n' $CONFIG
        pc_append "# dnsmasq logging" $CONFIG
        pc_append "# log-facility=/mnt/sda1/logs/dnsmasq.log" $CONFIG
        pc_append "# log-async" $CONFIG
        pc_append "# log-queries" $CONFIG
fi

 

[shooter40sw]

shhooter40sw, no need to reboot. Just run 'service restart_dnsmasq ' and go to etc/dnsmasq.conf to see if you messed something. I did numerous times.

Thats what I have been doing, but nothing shows up in the file, My USB is named x, so instead of sda1, I replace it with the x, and everything works but with this it isn't , I place sda1, it runs ok but the file is justs the same, no modifications... don't get it...

What is your full path to the dnsmasq.log file location? Look that up with:

find / -name dnsmasq.log

If the file is not present create it where you want it. Then run the find command again. Whatever the output is, this is your log-facility= path.

 

[thelonelycoder]

@shooter40sw An afterthought: When you change your paths only change the value of "log-facility=" and NOT in this line: if [ -d "/mnt/sda1" ]; then

 

[shooter40sw]

I did it, look:
I tried with the /tmp and without it and the dnsmasq.postconf is executable, I also commented the lines and without the comment. Thanks for the help

[shooter40sw]

Just tested it, it does not give me the error, but it does not add the lines in the tmp/etc/dnsmasq.conf file either after restarting the service

Then something is not right with your /jffs/scripts/dnsmasq.postconf
Did you make it executable with:

chmod a+rx /jffs/scripts/*

Also maybe post your full path from the find output and your content of dnsmasq.postconf.

Sorry @RMerlin to hijack this thread with this. But it'll blow over soon...

Great, apologies....How about creating your own topic?

I only did the chmod +x and just did the chmod a+rx on the file
