提交 VPS 信息进行质量测试

请创建临时 SSH 用户并提交 VPS 信息，中间件将检测硬件、网络速度、IP 质量、Ping / 延迟、路由、BGP 和状态。测试完成后会立即显示结果。

不同 OS 的配置指南

Ubuntu / Debian

请将生成的密码填写到 SSH password 字段。测试期间需要允许中间件服务器访问 SSH 22 端口。

# Ubuntu / Debian - run as root
export DEBIAN_FRONTEND=noninteractive
apt update
apt install -y sudo python3 python3-pip curl ca-certificates dnsutils iputils-ping traceroute mtr-tiny fio iperf3 speedtest-cli openssl

# If speedtest-cli is not available from apt, install it with pip
command -v speedtest-cli >/dev/null 2>&1 || python3 -m pip install --upgrade speedtest-cli

# Create or update the temporary probe user
PROBE_PASS=$(openssl rand -base64 24 | tr -dc 'A-Za-z0-9' | head -c 20)
id vpsprobe >/dev/null 2>&1 || adduser --disabled-password --gecos "" vpsprobe
echo "vpsprobe:${PROBE_PASS}" | chpasswd
usermod -aG sudo vpsprobe

# Allow the probe user to run test commands without being asked for sudo password
echo 'vpsprobe ALL=(ALL) NOPASSWD:ALL' >/etc/sudoers.d/vpsprobe
chmod 440 /etc/sudoers.d/vpsprobe
visudo -c

# Optional: enable password SSH login for the test window
mkdir -p /etc/ssh/sshd_config.d
cat >/etc/ssh/sshd_config.d/99-vpsprobe-password.conf <<'EOF'
PasswordAuthentication yes
KbdInteractiveAuthentication yes
EOF
systemctl reload ssh 2>/dev/null || systemctl reload sshd 2>/dev/null || true

# Prepare script directory used by optional IP Quality / Unlock probes
mkdir -p /opt/vps-perf-scripts
chmod 755 /opt/vps-perf-scripts

# Print the credentials for the public form
echo "VPS probe username: vpsprobe"
echo "VPS probe password: ${PROBE_PASS}"
echo "SSH port: 22"

快速 SSH 测试

ssh vpsprobe@YOUR_VPS_IP "whoami && sudo whoami && python3 --version && speedtest-cli --version"

评测完成后删除临时账号

deluser --remove-home vpsprobe 2>/dev/null || userdel -r vpsprobe 2>/dev/null || true
rm -f /etc/sudoers.d/vpsprobe /etc/ssh/sshd_config.d/99-vpsprobe-password.conf
systemctl reload ssh 2>/dev/null || systemctl reload sshd 2>/dev/null || true

AlmaLinux / Rocky / CentOS

请将生成的密码填写到 SSH password 字段。测试期间需要允许中间件服务器访问 SSH 22 端口。

# AlmaLinux / Rocky / CentOS - run as root

# If speedtest-cli is not available from the OS repo, install it with pip
command -v speedtest-cli >/dev/null 2>&1 || python3 -m pip install --upgrade speedtest-cli

# Create or update the temporary probe user
PROBE_PASS=$(openssl rand -base64 24 | tr -dc 'A-Za-z0-9' | head -c 20)

快速 SSH 测试

ssh vpsprobe@YOUR_VPS_IP "whoami && sudo whoami && python3 --version && speedtest-cli --version"

评测完成后删除临时账号

userdel -r vpsprobe 2>/dev/null || true

# If you enabled PasswordAuthentication only for this test, disable it again manually if needed.
systemctl reload sshd 2>/dev/null || true

Windows Server with OpenSSH

请以 Administrator 身份运行 PowerShell。将生成的密码填写到 SSH password 字段。Windows Server 需要启用 OpenSSH Server。

# Windows Server with OpenSSH - run PowerShell as Administrator

# Install and enable OpenSSH Server
$cap = Get-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0
if ($cap.State -ne 'Installed') {
    Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0

Start-Service sshd
Set-Service -Name sshd -StartupType Automatic

# Open Windows Firewall for SSH port 22

    New-NetFirewallRule -Name 'vpsprobe-sshd' -DisplayName 'VPS Probe OpenSSH Server' -Enabled True -Direction Inbound -Protocol TCP -Action Allow -LocalPort 22
}

# Generate a random password and create/update the temporary probe user
$bytes = New-Object byte[] 18
[Security.Cryptography.RandomNumberGenerator]::Create().GetBytes($bytes)
$ProbePassword = ([Convert]::ToBase64String($bytes) -replace '[^a-zA-Z0-9]', '').Substring(0,20)
$SecurePassword = ConvertTo-SecureString $ProbePassword -AsPlainText -Force

if (Get-LocalUser -Name 'vpsprobe' -ErrorAction SilentlyContinue) {
    Set-LocalUser -Name 'vpsprobe' -Password $SecurePassword
    Enable-LocalUser -Name 'vpsprobe'
} else {
    New-LocalUser -Name 'vpsprobe' -Password $SecurePassword -FullName 'VPS Probe User' -Description 'Temporary VPS performance probe user'
}

# Give the user enough permission for the test window
if (-not (Get-LocalGroupMember -Group 'Administrators' -Member 'vpsprobe' -ErrorAction SilentlyContinue)) {
    Add-LocalGroupMember -Group 'Administrators' -Member 'vpsprobe'
}

# Ensure OpenSSH password authentication is enabled
$sshdConfig = 'C:\ProgramData\ssh\sshd_config'
if (Test-Path $sshdConfig) {
    $content = Get-Content $sshdConfig -Raw
    if ($content -match '(?m)^#?PasswordAuthentication\s+') {
        $content = $content -replace '(?m)^#?PasswordAuthentication\s+.*$', 'PasswordAuthentication yes'
    } else {
        $content += "`r`nPasswordAuthentication yes`r`n"
    }
    Set-Content -Path $sshdConfig -Value $content -Encoding ascii
}
Restart-Service sshd

# Print the credentials for the public form
Write-Host "VPS probe username: vpsprobe"

快速 SSH 测试

ssh vpsprobe@YOUR_VPS_IP "whoami && hostname"

评测完成后删除临时账号

Remove-LocalGroupMember -Group 'Administrators' -Member 'vpsprobe' -ErrorAction SilentlyContinue
