Introduction

To troubleshoot cloud backup issues, you will need to troubleshoot the connection from the bootable media or Virtual Appliance to Acronis Datacenter.

Starting from Acronis Cyber Protect 21.07, Virtual Appliance and bootable media contain built-in tcpdump utility for collecting network tracing logs.

Solution

To capture the tcpdump log you will need to perform the following actions:

1. Start the command shell, press CTRL+SHIFT+F2 while in the bootable media or Virtual Appliance UI.

2. Issue /bin/sshd to start ssh daemon.

3. Connect to the media using SSH client (like WinSCP or Putty)

   Connecting using WinSCP utility: click to expand

   1. On a Windows machine, install the WinSCP utility which you can get from http://winscp.net/eng/download.php. WinSCP (Windows Secure CoPy) is a free and open source SFTP, SCP, and FTP client for Microsoft Windows.
   2. Launch the WinSCP utility on the machine where you installed it.
   3. In the Host name field type your Virtual Appliance IP, the same as in the vSphere console or IP address of Acronis Bootable Media. The default login:password is root:root .
   4. The protocol should be set to SCP and then click on Login.
   5. You will get a window with all the directories of the Virtual Appliance (Windows Commander-like interface)

4. Start logging of tcpdump utility:

   # tcpdump -i eth0 -s 64 port 443 or port 44445 -w /var/lib/Acronis/tcpdump.pcap

5. Reproduce the issue
6. Press Ctrl+C to stop tcpdump logging
7. Download the created dump from /var/lib/Acronis using WinSCP.
