Features

  • Prevents HTTP 404 page not found messages if used in conjunction with dnsmasq IP redirects (edgeos-dnsmasq-blacklist provides dnsmasq redirection and blacklisting functionality)

Compatibility

  • edgeos-pixelserv has been tested on the EdgeRouter ERLite-3, ERPoe-5, ER-X:
    • EdgeOS versions v1.7.0-v2.0.9
  • Note: the debian package will not successfully install on a UniFi Gateway, since there is also a default HTTP port 80 listener configured all interfaces

Change Log

Installation

  • edgeos-pixelserv installs itself as a service into /etc/init.d/pixelserv

  • The installation will modify the router's configuration settings to move "service gui http-port 80" to "service gui http-port 8180" to prevent conflict with pixelserv on port 80

  • Using apt-get - works for all routers

  • Using dpkg - best for disk space constrained routers

apt-get Installation - ERLite-3, ERPoe-5, ER-X & ER-X-SFP

  • Add the blacklist debian package repository using the router's CLI shell
configure
set system package repository blacklist components main
set system package repository blacklist description 'Britannic blacklist debian stretch repository'
set system package repository blacklist distribution stretch
set system package repository blacklist url 'https://raw.githubusercontent.com/britannic/debian-repo/master/blacklist/public/'
commit;save;exit
  • Add the GPG signing key
sudo curl -L https://raw.githubusercontent.com/britannic/debian-repo/master/blacklist/public.key | sudo apt-key add -
  • Update the system repositorities and install edgeos-pixelserv
sudo apt-get update && sudo apt-get install edgeos-pixelserv

dpkg installation - Best for disk space constrained routers

EdgeRouter ERLite-3, ERPoe-5 and similar MIPS based Edgerouters

curl -L -O  https://raw.githubusercontent.com/britannic/pixelserv/master/edgeos-pixelserv_1.0.8_mips.deb
sudo dpkg -i edgeos-pixelserv_1.0.8_mips.deb

EdgeRouter ER-X & ER-X-SFP

curl -L -O  https://raw.githubusercontent.com/britannic/pixelserv/master/edgeos-pixelserv_1.0.8_mipsel.deb
sudo dpkg -i edgeos-pixelserv_1.0.8_mipsel.deb

Removal

  • Removal will modify the router's configuration settings to move "service gui http-port 8180" back to the default "service gui http-port 80"

EdgeMAX ERLite-x & EdgeMax ER-X

sudo apt-get remove edgeos-pixelserv
