Allow Adobe Flash for certain sites after 2021 EOL announcement

You can still use Adobe Flash as of January 2021 by "whitelisting" certain sites. I mostly use it to manage some old Enterprise Appliances. All you have to do is edit your mms.cfg file, located in:  

C:\Windows\System32\Macromed\Flash 

or

C:\Windows\SysWOW64\Macromed\Flash

So, the file should look be edited as following:

EOLUninstallDisable=1
AutoUpdateDisable=1
EnableAllowList=1
AllowListRootMovieOnly=1
AllowListURLPattern=*://mydomain.example.com

According to the Adobe Flash Admin guide, AllowListUrlPattern syntax is the follwing:

AllowListUrlPattern = <scheme> ://<host>:<port>/<path>
<scheme> = ‘*’ | ‘http’ | ‘https’
<host> = <any char except ‘.’ and ‘*’>
<port> (optional) = <any valid port number>
<path> = ‘/’ <any chars>
 
With EnableAllowList=1 set, administrators can then specify a discrete URL or pattern to allow

Get Telegram notifications for APC UPS using SNMP traps in Linux

In this post I am going to explain how I used SNMP traps on a Linux Debian system in order to get some telegram notifications. I used them in order to be informed in case our company UPS systems runs on battery. First of all, you have to setup and test a Telegram Notification script. I used the one here: https://github.com/samsulmaarif/telegram-notify , it is very easy to install and use. The binary is installed in: /usr/local/bin/telegram-notify We assume that you already have a telegram bot running. The two things you 've got to find are your bot api-key and chat id or Channel id. In case you are not yet using a telegram bot, there are plenty of guides showing how to setup one and how to get your user-id. In order to get SNMP traps from your UPS Network management card, you should first enable them in the "Notifications". Just enter your Linux hostname as a trap receiver. First install snmpd and snmptrapd sudo apt install snmpd snmptrapd Edit your config files: The o...

Setting up your openwrt adsl router for Forthnet IPv6 (Dual Stack) - Static Pilot

I am using a Ubiquiti AirRouter flashed with OpenWrt as a PPPoE client and my old linksys ADSL modem/router is configured in bridged mode and only handles the ADSL connection.  This setup applies to openwrt Attitude Adjustment 12.09 and it is updated on Nov 2014 You have to install the follwing packages: dhcp6-client radvd opkg update opkg install radvd dhcp6-client If you are using the Luci web i/f,  you should enable "Enable IPv6 negotiation on the PPP link" on the WAN advanced settings. It is more efficient though to do the changes via cli: config interface 'wan' option _orig_ifname 'eth1' option _orig_bridge 'false' option ifname 'eth1' option proto 'pppoe' option password 'somepasshere' option username 'username.ath.forthnet.gr@stv6forthnet.gr' option ipv6 '1' option keepalive '5 5' Then, edit /etc/config/dhcp6c : config in...
