    Run Astaro HTTP proxy database localy

    1. ssh to ASG and login with loginuser

    2. su - root

    3. cc set http sc_local_db [disk][mem][none] (Choose what you prefer)

    4. /var/mdw/scripts/httpproxy restart

    Websurfing will be extremely slow until the database has downloaded and been put into place. The time is link speed dependent.

    Bandwidth usage - IFTOP

    Astaro also offers the command 'iftop' to see the live traffic and traffic statistics. 

    One can see the traffic live on an interface for Source Host, Destination Host, and Ports. 

    The peak and accumulative traffic is also displayed.

    Run 'iftop'


    root # iftop -i eth1

    number of established connections:

    less /proc/net/ip_conntrack | grep ESTA | wc -l



    number of all connections:

    Saving Snapshots of TOP automatically every half hour

    create a cron job with,

    top -b -n 1 >>/tmp/top-report.txt

    An entry for each CPU core, and possibly another if the CPU(s) has hyperthreading:

    cat /proc/cpuinfo


    stopped and started again the HTTP proxy:

    "/var/mdw/scripts/httpproxy stop" and "/var/mdw/scripts/httpproxy start"


    Restarting MiddleWare:

    service mdw restart

    (from root)

    Warning: it doesn't cause a complete reboot, but it does cause an HA failover, interruption of any up/downloads and VoIP calls, etc. 



    Find what is taking the space type

    df –h

    df will only tell you how full the disk is.

    du will tell you what files/folders are using the most space

    I'd recommend:

    cd /var/storage

    du -sh *

    find the offending directories


    What kind of CPU

    "cat /proc/cpuinfo"?


    Determine if the disk is overloaded

    vmstat -d 5


    vmstat -d | head -2 ; vmstat -d 5 | grep hda

    if hda is your hard disk; sda for scsi

    That should have similar output. 

    The '5' is 5 second updates.

    You'll have to look at the differences between the lines to figure out how many IO's you're getting in those 5 seconds, and whether you're saturating the disk or not.


    See detailed info about your eth:

    # ethtool eth1


    -mii-diag eth1


    webadmin passwd lost

    A user may use the following commands to reset the system passwords:




    Ctrl c


    Upon saving the file and exiting, the admin may immediately navigate to WebAdmin and re-specify all passwords for the system accounts of Astaro Security Linux.


    DNS Flush cache option missing in V7

    the current workaround is to restart the DNS proxy from the command line as root with the following command:

    /var/mdw/scripts/named restart


    To change version number

    login as loginuser

    su -

    edit /etc/version

    save the file

    restart the ASG so the new version is displayed in Webadmin dashboard


    Change NIC order

    login as loginuser

    su -

    edit /etc/udev/rules.d/70-persistent-net.rules

    save the file

    restart the ASG so the new order is loaded.


    Locked out - How to regain all logins

    1) Shutdown the firewall and connect a screen and a keyboard to the firewall

    2) Power on the firewall, wait until the GRUB-loader starts and press ‘ESC’

    3) Select ‘Astaro Security Gateway 7.2’ (not previous or rescue!)

    4) Press ‘e’ to edit and select the 2nd entry

    5) Press ‘e’ once again and enter ‘init=/bin/bash’

    6) Press ‘ENTER’ and ‘b’ to boot up

    7) Now you are able to change the passwords for ‘loginuser’ and ‘root’

    8) After that press CTRL + ALT + DEL to reboot the system and wait until you get the login prompt

    1. cc [Press ENTER]

    2. RAW [Press ENTER]

    3. system_factory_reset [Press ENTER]
