46015: Acronis Bootable Media: Troubleshooting Network Browsing Issues

    In some rare cases there can be some issues during network browsing while working with Acronis bootable.media.

    Symptoms

    You booted machine with Acronis bootable media. You try to select a share as source or target. You either don't see any shares or loading takes too much time.

    Solution

    Follow step-by-step instructions below to troubleshoot the issue.

    Please do not collect tcpdump unless it's requested by Acronis support.

    Notes:
    In order to collect output of a command do the following:
    command > file_for_output.txt
    Then export it with help of this article.
    If you need to view some file and easily navigate in it, you can use the less program.
    While viewing a file you can use search (press / and type in the pattern) or navigate with arrows keys. Press 'q' to exit.

    Samba shares (SMB/CIFS)

    1. Try to ping the share host by hostname and IP (#ping share_name):
      - Click Ctrl+Alt+F2 to switch to the shell.
      - Type ping share_name
      - Check whether ping was successful.
      (Issue /bin/product to switch back to GUI)
      In some cases when DNS resolving service works incorrectly it can be only possible to access share by IP address. If share is not accessible - check network and share's accesibility from another machines.
    2. Check /tmp/asamba.log after reproducing for any possible errors (switch to the shell and issue #less /tmp/asamba.log). If you see an error - proceed accordingly or contact Acronis Customer Central with a screenshot of the error message and information collected as described below.
      3. Go to the collect information step and contact Acronis Customer Central with the information collected.

    NFS shares

      - Check whether ping was successful.
      (Issue /bin/product to switch back to GUI)

    3. Check /tmp/nfs-*.log for any possible errors. If you see an error - proceed accordingly or contact Acronis Customer Central with a screenshot of the error message and information collected as described below.

    SFTP server

    Distinguish between FTP, FTP over SSH and SFTP!

    2. Find log in /tmp/sftp-*.log, check it for any errors. If you see an error - proceed accordingly or contact Acronis Customer Central with a screenshot of the error message and information collected as described below.
    3. Collect /etc/ssh/sshd_config from the SFTP server. Location may differ depending on Linux distribution you're using.
    4. Check and collect #iptables -t nat -L
    5. Go to the collect information step and contact Acronis Customer Central with the information collected.

    Collect information

    1. Description of the performed troubleshooting steps and their results.
    2. System Report under the bootable media after you reproduce the issue (it will collect the necessary logs). See Acronis Backup 11.7/11.5 Generating System Report.
    3. System Report under the operating system if possible. Collect System Report from the machine in question: see instruction for Acronis Backup 11.7/11.5 Generating System Report, if this fails for any reason, you can use this AcronisInfo Utility.
