sudo yum install zjunet

OpenWrt (opk)

Download .opk package from Release Page (onto your router), Run opkg install ./zjunet_<version>_all.opk.

Other Linux (Build from source code)

xl2tpd -v; curl -V; dig -v # Check installation of dependencies. There should be 3 version numbers.
# Under proper directory
git clone https://github.com/QSCTech/zjunet.git
cd zjunet
sudo ./install.sh
# If update is necessary, run `git pull` and `sudo ./install.sh`
# If you are setting up a server, we suggest you run `zjunet wlan disable` to disable WLAN capability.

ATTENTION Requirement check will NOT be done running ./install.sh. Please run xl2tpd -v, curl -V and dig -v to verify the installation.

Troubleshooting

Packet lose

This is a known issue. When overlapping VPN and ZJUWLAN, network packet may be lost. (because of nexthop in routing table).

Contributions to this issue are welcomed. (Maybe using iptables)

ppp0 may disappears on OpenWrt

Set lcp-echo-failure larger in /etc/ppp/options.
