Installation

If you meet any problem during or after the installation, check Troubleshooting section below in this documentation.

Debian / Ubuntu (deb)

Configure ZJU mirrors from manual. Ubuntu/Debian
Run these command.

curl https://mirrors.zju.edu.cn/openzjunet/zjumirrors.pgp | sudo tee /etc/apt/trusted.gpg.d/zjumirrors.asc
curl https://mirrors.zju.edu.cn/openzjunet/zjunet.list | sudo tee /etc/apt/sources.list.d/zjunet.list
sudo apt-get update
sudo apt-get install zjunet

The installation has completed.
If you are setting up a server, we suggest you run zjunet wlan disable to disable WLAN capability.

Fedora / CentOS (rpm)

Configure ZJU mirrors from manual. Fedora/CentOS
Configure EPEL of ZJU mirrors (Taking CentOS installation as an example)
1. Run yum install epel-release to install EPEL.
2. Edit /etc/yum.repos.d/epel.repo , uncomment lines begin with #baseurl= (Remove leading # sign) and comment lines begin with mirrorlist= (Prepend # sign)
3. Edit /etc/yum.repos.d/epel.repo , replace https://download.fedoraproject.org/pub with https://mirrors.zju.edu.cn .
Run these command.

curl https://mirrors.zju.edu.cn/openzjunet/zjumirrors.pgp | sudo tee /etc/pki/rpm-gpg/RPM-GPG-KEY-ZJUMIRRORS
curl https://mirrors.zju.edu.cn/openzjunet/zjunet.repo | sudo tee /etc/yum.repos.d/zjunet.repo
sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-ZJUMIRRORS
sudo yum install zjunet

The installation has completed.
If you are setting up a server, we suggest you run zjunet wlan disable to disable WLAN capability.

OpenWrt (opk)

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

Arch Linux (AUR)

Simply run yay zjunet to build the package from AUR and install it.

Keep in mind that a fresh install without internet connection is almost impossible. Please complete installation before connecting to the intranet.

Other Linux (Build from source code)

xl2tpd -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 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.

Test ppp before setting routes

RPM Package

usage

Unable to open /var/run/xl2tpd/l2tp-control for writing: No such file or directory

user.sh的用户名过滤貌似有问题

会出现

01 No such tunel 'zju-l2tp-zjuvpn'

Ali DNS is not good in my experience

Much worse than 114DNS most of the time in terms of speed, stability (sometimes high packet loss rate), and accuracy.

ppp0 will disappear

xl2tpd version:  xl2tpd-1.3.6
Linux OpenWrt 3.3.8 #74 Sun Jun 23 12:52:20 CST 2013 mips GNU/Linux

dns备选方案更改

将

10.76.8.111
10.202.68.222

删除，并换为

10.202.68.43

因为原111已失效（硬盘挂，重装）；222已不被使用（可能不属于我们；且可能被配置了iptables；状态未知）

wlan web adress question

I can't use your wlan script and I think the url may be wrong.
That's the url I get :
logout:
RESPONSE=$(curl "https://net.zju.edu.cn/cgi-bin/srun_portal" -H "Content-Type: application/x-www-form-urlencoded" -d "action=logout" -s | iconv -c -f gbk -t gbk)
login:
RESPONSE=$(curl "https://net.zju.edu.cn/cgi-bin/srun_portal" -H "Content-Type: application/x-www-form-urlencoded" -d "action=login&username=${USERNAME}&password=${PASSWORD}&ac_id=3&type=1&is_ldap=1&local_auth=1" -s | iconv -c -f gbk -t utf8)

Now available on QSC's linux repo

HERE:

Usage:

xl2tpd: 最新版的1.3.1似乎不能拨两个以上的VPN

强制踢下线

replace xl2tpd-control with simple shell script

Seems that xl2tpd-control has some strange bugs in Debian / Ubuntu

一键安装脚本

test if network is ok, don't set up ip routes if not avaliable

nexthop 网速测试

客户端手抖。

install.sh

cp *.sh -> /usr/local/lib
echo link > /usr/local/bin/zjunet

拨 VPN (>= 3) 的时候网络异常慢

但是分开设置路由表又是好的，或者 C(3, 2) 也是好的。
非常奇怪。

The availibilty of xl2tpd-control

It is a small wrap-up script (or bin?) around the control file (e.g. /var/run/xl2tpd/l2tp-control). Originally, xl2tpd is controlled by writing commands into the control file, the way kernel often uses in /proc/ and /sys/. Some distributions provide this handy tool, but others not.

If we echo strings to the control file directly, we can remove the dependency on xl2tpd-control.

58.* some classroom computers (especially East 6,7)
210.* the public CERNET IP of most ZJU servers, which can be reached directly in the Intranet. (Most of them do have a 10.* IP, but sometimes school DNS just returns the public ones.)

P.S. In ZJG dorm, only DNS and L2TP gateway servers can be reached directly: https://gist.github.com/Hexcles/6562821#file-vpn-dorm-sh-L35-L36
