Serv00 provides three ports and allows software installation. It’s usable for light testing, though the latency is quite noticeable.

---

1. Configure DevilWEB

Log in to DevilWEB using the account credentials provided in the email from Serv00.

1. Set Up Ports

Click "Add Port" — you can add up to 3 ports.

After adding, it should look like this:

2. Check Assigned IP Address

Add an A record in your domain’s DNS settings (e.g., x.xx.com) pointing to this IP for easier access in daily use.

---

2. Configure the Server & Install frp

Log in via SSH using the credentials from Serv00’s email.

1. Install frp

Download frp from the official GitHub releases page:

wget https://github.com/fatedier/frp/releases/download/v0.35.0/frp_0.35.0_freebsd_amd64.tar.gz
tar -zxvf frp_0.35.0_freebsd_amd64.tar.gz && mv frp_0.35.0_freebsd_amd64 frp && chmod 777 frp

This creates a frp folder in your current directory.

2. Configure frps.ini

Enter the frp directory and create/edit frps.ini:

[common]
bind_port = A  # Replace with your configured port A
bind_addr = 0.0.0.0

# Log settings
log_file = /home/<your-username>/frp/logs/frps.log  # Update with your actual username
log_level = info
log_max_days = 7

# Privilege mode
privilege_mode = true
privilege_allow_ports = B,C  # Replace with your ports B and C
token = xxxxxxxx

# Heartbeat & authentication
heartbeat_timeout = 90
authentication_timeout = 0

# Connection pool
max_pool_count = 100

3. Configure frpc.ini (on Serv00 side)

[common]
server_addr = 127.0.0.1
server_port = A  # Your port A
token = xxxxxxxx

[route_webs_visitor]
type = stcp
role = visitor
server_name = route_webs
sk = 123456  # Shared secret key
bind_addr = 0.0.0.0
bind_port = B  # Your port B

[route_rdp_visitor]
type = stcp
role = visitor
server_name = route_rdp
sk = 123456
bind_addr = 0.0.0.0
bind_port = C  # Your port C

---

3. Configure Local Client

1. Local frpc.ini (example using Docker)

vim /data/docker/frp/frpc.ini

[common]
server_addr = x.xx.com  # Your domain or Serv00 IP
server_port = A         # Port A
token = xxxxxxxx

[route_webs]
type = stcp
sk = 123456
local_ip = 192.168.1.1   # Your local service IP
local_port = 80          # e.g., web server

[route_rdp]
type = stcp
sk = 123456
local_ip = 192.168.1.2
local_port = 3389        # Windows RDP

2. Run frpc in Docker

docker run -d \
  --restart unless-stopped \
  -v /data/docker/frp/frpc.ini:/etc/frp/frpc.ini \
  -v /data/docker/frp/logs:/etc/frp/logs \
  --name frpc-01 \
  snowdreamtech/frpc:0.35.0

Check logs:

docker logs frpc-01

---

4. Set Up Process Monitoring with PM2

1. Install PM2

bash <(curl -s https://raw.githubusercontent.com/k0baya/alist_repl/main/serv00/install-pm2.sh) && source ~/.bashrc

pm2 start -x ./frp/frps -n frps -- -c ./frp/frps.ini
pm2 start -x ./frp/frpc -n frpc -- -c ./frp/frpc.ini

Check status:

pm2 ls

View logs:

pm2 logs

2. Add Cron Job for Auto-Restart on Reboot

In DevilWEB, go to the Cron jobs tab → Add cron job:

• Specify time: After reboot
• Form type: Advanced
• Command:

  /home//.npm-global/bin/pm2 resurrect

3. Save PM2 Snapshot

pm2 save

---

5. Test the Setup

Postscript

After running for a few days, I noticed that DevilWEB’s cron jobs get cleared automatically. To address this, I added a monitoring script using QingLong Panel (other schedulers work similarly).

1. Install Dependency: sshpass

2. Add Monitoring Script

#!/bin/bash

URL="x.xx.com:B"  # The public URL/port you exposed (e.g., a web service for health check)

HTTP_STATUS=$(curl -o /dev/null --silent --head --write-out '%{http_code}\n' "${URL}")

echo "HTTP status code: ${HTTP_STATUS}"

if [ "$HTTP_STATUS" != "000" ]; then
    echo "Connection is healthy. Skipping recovery."
    echo "finished"
    exit 0
fi

HOST=""          # Serv00 SSH hostname
USERNAME=""      # Serv00 SSH username
PASSWORD=""      # Serv00 SSH password

sshpass -p "${PASSWORD}" ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -tt "${USERNAME}@${HOST}" << EOF

if ps ax | grep -v grep | grep "frps" > /dev/null; then
   echo "frps process is running. Skipping."
else
   echo "frps not found. Restoring PM2 snapshot..."
   /home/<your-username>/.npm-global/bin/pm2 resurrect
fi

exit

EOF

echo "finished"

⚠️ Replace <your-username> with your actual Serv00 username.

3. Schedule the Script

Set up a periodic task in QingLong (or your scheduler) to run this script every few minutes.
