# What Should I Do If the Service Port Is Used by the Agent?

Cloud Eye Agent uses HTTP requests to report data. Any port in the range obtained from path /proc/sys/net/ipv4/ip_local_port_range may be occupied. If any service port is used by the Agent, you can modify path /proc/sys/net/ipv4/ip_local_port_range and restart the Agent to solve the problem.

#### Procedure

1. Log in an ECS or BMS as user root.
2. Open the sysctl.conf file:

   vim /etc/sysctl.conf

3. (Permanent change) Add new ports to the sysctl.conf file:

   net.ipv4.ip_local_port_range=49152 65536

4. Make the modification take effect:

   sysctl -p /etc/sysctl.conf

   - The permanent change still takes effect after the ECS or BMS is restarted.
   - For temporary modification (which expires after the ECS or BMS is restarted), run # echo 49152 65536 > /proc/sys/net/ipv4/ip_local_port_range.
5. Run the following command to restart the Agent:

   /usr/local/telescope/telescoped restart

   For Windows, in the directory where the Agent installation package is stored, double-click the shutdown.bat script to stop the Agent, and execute the start.bat script to start the Agent.
