eLTE collect step_note

1.1 Run the following command to capture packets on the MRS server: The procedure is as follows:

1. 1. 1. 1. 1. 1. Capture packets on the MRS server. The entire problem is captured. Use PuTTY to log in to the MRS server.

               2. (1) cd /opt/UBP

               3. 2. Run the. Svc_profile.sh command to execute environment variables.

               4. 3. Run the Ifconfig –a command to query the network port used by the IP address of the current server.

               5. 4) tcpdump -i eth0 -s 2000 -n -w MRS.pcap (eth0 is the network port of the current server and is subject to the actual situation.)

               6. 5. The ctrl+c stops capturing packets.

               7. 6) chmod 777 MRS.pcap

               8. Download MRS.pcap to the local computer.

               9. Capture packets first, and then perform related service operations and observation.

                  Operation Procedure

Step 1:Use an SSH tool (for example, PuTTY) to log in to the server. The user name is ubp, and the password is eLTE@com123 (default password). If the password is changed, use the new password to log in to the server. MRS server ip is :180.180.180.104

The login is successful, as shown in the following figure. Switch to the super user.

Command: su root

Password: eLTE@com (default password)

STEP 2: Run the following command to capture packets:

Tcpdump -s 2000 -i eth0 (network adapter name) -w call_mdcxxx.cap (file name)

Note:

The NIC name is not clear. You can run the ifconfig command to query the NIC name, as shown in the following figure.

On the puuty page, run the ctrl+c command to capture packets. If the permission is insufficient, run the following command to modify the permission: Chmod 777 * (* indicates the name of the file whose permission needs to be modified /home/ubp/call_mrsxxx.cap)

Use FileZilla to extract packet capture files. (The directory is /home/ubp/call_mrsxxx.cap.)
