Pre-built binaries

CMD mode

./srun login -u USERNAME -p PASSWORD -i IP [-s AUTH_SERVER]

AUTH_SERVER should contain protocols, e.g.

Which IP to be authorized?

srun support three methods of specifying IP:

  • use -i IP to specify ip
  • use -d to auto detect ip
  • use --select-ip to select ip
specify IP

You need to check the IP address of each network interfaces in advance and choose the correct IP to be authorized.

detect IP

srun support automatic IP detection, it determines the IP address from the information returned by the authentication server.

This is useful in cases where you only have one IP address to authorize.

If you are multidialing and have multiple legitimate IPs at the same time, you need to authorize multiple IPs at the same time, this method will not authorize all IPs properly.

select IP

This method is similar to the first method, except that it saves you the trouble of manually querying all the IPs.

srun will query all the legitimate IPs in advance and then print a list of IPs for you to choose from.

$ ./srun login -u USERNAME -p PASSWORD --select-ip
Please select your IP:
you choose

Please note that when your computer has only one IP that can be authorized, we will simply omit the selection process and use this IP.

Using a Config

Usually, it is sufficient to specify the information directly using command line parameters.

In order to meet the needs of multi-dial users, srun support reading multiple user information from a config file.

./srun login -c config.json

config file template

    "server": "",
    "strict_bind": false,
    "double_stack": false,
    "retry_delay": 1000,
    "retry_times": 3,
    "n": 200,
    "type": 1,
    "acid": 12,
    "os": "Windows",
    "name": "Windows 98",
    "users": [
            "username": "username1",
            "password": "password1",
            "ip": ""
            "username": "username2@cmcc",
            "password": "password2",
            "if_name": "macvlan1"

As you can see, we support ip or if_name.

If your IP will not change, you can use ip to specify directly.

But for multi-dial, IP may be automatically assigned by DHCP and may change, at this time we suggest to use if_name to specify the corresponding NIC name, we will automatically query the IP under that NIC as the IP to be authorized.

On windows, the NIC name should be like {93123211-9629-4E04-82F0-EA2E4F221468}, use --select-ip to see.

Operator selection

Some colleges support network operator selection, which implemented by append the operator code to the username.

Operator code:

  • 中国电信: [chinanet, ctcc]
  • 中国移动: [cmcc]
  • 中国联通: [unicom, cucc]
  • 校园网: [xn]

For example, if you choose cmcc, just append @cmcc to your username, like 202112345@cmcc.

This code needs to be confirmed by capturing packets.

TLS support

To keep the binary as small as possible, the pre-compiled binary remove the non-essential tls support

If your authentication system uses https, You need to compile it yourself with feature tls enabled.

cargo build --features "tls" --release
