There is no preset password in OpenWrt! You need to set one at your first login per telnet or the WebUI.

As you can see here development, there are always two branches which are being actively worked on. OpenWrt trunk, which is bleeding edge, codename 'Attitude Adjustment', and the current stable release. Do

cat /etc/banner

to see the exact revision. Use that information for bug reports and questions in the forum. Also use it, to look up information yourself: https://dev.openwrt.org/browser

→ generic.debrick

Install one, e.g. LuCI.

→ user.beginner.cli

→generic.overviews

→generic.failsafe

There are three WebUIs available. All are FOSS, thus you can adapt each of them to your specific needs and likings.

By removing packages you installed after flashing OpenWrt onto your Router. You cannot remove packages on the SquashFS partition!

Please send reproducible bugs to our ticket system.

You can check yourself. The OpenWrt repositories are brows-able by web browser. E.g.

• stable • ar71xx
• trunk • lantiq
• etc.

Possible reasons:

• it makes no sense to have this software in the repositories, because it is too bloated/not suited for embedded environments
• nobody has thought on packaging this software for OpenWrt yet

Possible solutions:

• create the package yourself: Creating a package
• do nothing and wait until package becomes available

That be because the firewall-package comes with a configuration already. Certain user chains are created, and packets put into them. When you then later try to catch packets in the INPUT chain, there won't be any, because they are being put into user chains (maybe something like wan_input, lan_input) before that.

Anytime you can type

iptables -L 

to see how things are currently setup, but best thing is, to always know your own setup.

E.g. so:

cat /tmp/dhcp.leases

Like on any Linux system, you can use crond. Please consult /etc/crontabs/root

Unless you installed some other log daemons OpenWrt uses by default busybox-klogd and busybox-syslogd for logging. Both use the same circular buffer, which can be from to in size. Default is . Access with command

logread

That's right.

Typically you will see something like this:

root@OpenWrt:~# iwconfig wlan0 mode master
Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0 ; Invalid argument.

It's documented here.
