[OpenWrt-Users] Is there anybody can find /var/log/dmesg in OpenWRT ?

[Tymon]

Hi all,


Why can't I find the /var/log/dmesg file under openwrt (the busybox built-in tool 'dmesg' is work fine) ???


Any hint will be appreciated!

I believe you have to use logread-

Thank you for your answer, but I only want to display the kernel message.
I expect to use 'tail -f /var/log/dmesg' to read the kernel debug message on my device that without
serial console.

If you want to see older kernel messages, you will have to set up syslog
logging to a host with sufficient disk. If the last feww hundred messages
will do, why don't you just use the dmesg command?
