C448HD C450HD | Users & Administrator's Manual

Open the folder on the PC to which you commanded the application to send the
information and locate and open the file 'net.pcap'.

Alternatively, run Tcpdump

without

the utility.

➢

To run tcpdump without the utility:

Access the phone via SSH and run the following commands:

setprop ac.ac_tcpdump.timeout <seconds>

After defining the capturing time as shown in the preceding command, start the capture:

setprop ac.ac_tcpdump 1

Tcpdump capture file will appear in this location:

/sdcard/recording/net.pcap

After running Tcpdump, reproduce the issue.

Execute the following command from your PC command prompt (cmd):

scp -r admin@%deviceIp%:/sdcard/recording/ %FolderOnPc%

Open the Android Phone Utility (see

Android Phone Utility

on page 105 for more

information about the application), enter the phone's IP address, click the adjacent

SSH

Connect

button and browse to a folder on the PC to which to send the information.
