By default Linux ignores Broadcast and Multicast ICMP messages. That's why you need to enable it first:
sysctl -w net.ipv4.icmp_echo_ignore_broadcasts=0To join any mutlicast address (e.g. 224.10.10.10/24) just add it to your active interface (e.g. eth0) and append the keyword autojoin at the end:
| import qrcode | |
| def createQr(vwz,iban,bic,recipient,amount,filename="epc_qr"): | |
| # The docs can be found here: https://pypi.org/project/qrcode/ | |
| qr = qrcode.QRCode(error_correction=qrcode.constants.ERROR_CORRECT_M) | |
| qr.add_data("BCD\n") | |
| qr.add_data("002\n") | |
| qr.add_data("1\n") | |
| qr.add_data("SCT\n") |
When you are unable to login to the unifi controller or forgot admin password, you can restore access using SSH and manipulating mongodb directly.
Do not uninstall unifi controller - most of the data is not stored in mongodb. In case you thought a mongodb backup would be sufficient, you may have fucked up already, just like me. However I managed to write this "tutorial" for anyone to not run into the same trap.
The git command-line utility has plenty of inconsistencies http://steveko.wordpress.com/2012/02/24/10-things-i-hate-about-git/
A GUI like http://sourcetreeapp.com is often helpful, but staying on the command line usually quicker. This is a list of the commands I use most frequently, listed by functional category:
