Hello all,

Can someone help me with a tutorial on how to prepare a USB to use to write System Log on it?
I want to mention that I am not an experienced user in ddwrt and configuration commands,I need concrete
details on how I could use it.

ubs 3gb format Ext4
Linksys WRT1900ACS V2
Firmware Version DD-WRT v3.0-r48322


Thank you!

I believe USB sticks use EXT2, and EXT3 & 4 are for USB HDD. If this doesn’t help you, then I would telnet/ssh into the router and navigate the to the location you want to place the logs with commands ‘ls’ & ‘cd’ and copy the location from there to your settings.

[oliver44]

I changed the format of the stick with EXT2, I guess I need to configure a script to send write system logs to USB memory ?

Or what should be the command line commands via ssh?

[AndyOxon]

I thought mine was set to a local path, but I can’t find it now. I might have been thinking of a different firmware. I’m just trying to find anything useful for you…

[AndyOxon]

I think this is what you need: https://wiki.dd-wrt.com/wiki/index.php/Logs --Saving the logfile across reboots

[oliver44]

I apologize but my English is not the best, I just have to copy and save this script in startup script, I don't have to configure anything anymore ?

killall syslogd
syslogd -L -s 8192 -O /opt/var/log/messages

#credits to frater for the commands

[AndyOxon]

From the guide, I would place it in Administration > Management > CRON.

Reboot and see if the logs are where you want them. If Not, then place the script into Administration > Commands > Shutdown instead.

And if after rebooting you can't se your logs still, place it in both CRON AND Shutdown command.

You may just need to SSH in and enter the 2 commands, but I don't know if this will be permanent. Test, test, test.

Good Luck!

A cron job is not necessary, I think.

Just Administration/Commands and Save as USB so that you know that it will run once the USB drive is up.

Alternatively Save as startup but begin with:
is-mounted /opt

[AndyOxon]

I'm going to assume that /opt is not mounted. So be sure to replace /opt/var/log/messages with /tmp/mnt/sda1/directory_name

[oliver44]

I reworked the stick format, can you please tell me what the final script should look like and where I should add it concretely!

Thank you for help

[AndyOxon]

why is ur USB now mounted to /jffs?

[egc]

As you only made /jffs

Administration/Commands and Save as USB:

sorry I got the picture wrong!

syslogd should do that, at least on my router
