    Tony Ellis replied to a discussion, Interesting ethernet problem

    Possibly PS - but think unlikely...

    https://www.sraellis.tk/frame-34-voltages.html shows the average for the two voltages monitored has remained stable - but that of course would not pick up any instantaneous peaks or dips or problems on other voltage rails...

    Haven't looked in the machine. It is still running with the 'broken' NICs inside it and wasn't powered off, just added the usb ethernet dongles. It went straight back into operation and hasn't missed a beat since.

    We will see what happens when the replacement arrives (coming from overseas - replacements for dual NIC PCI 32-bit gigabyte adaptors are not available here... being Mini-ITX have only one PCI slot).

    Interesting ethernet problem

    This is a short story of an interesting fault. But first a small simplified part of my system setup

    The problem was this appearing at random times... only lasted for about a few seconds at most for each disruption which could be up to several hours apart.

    Tried everything to fix "alice" over about two weeks - nothing helped. Then woke up one morning to find "may" had totally
    lost internet connectivity. A check showed the e1000 PCI card in "may" had "died". Another is on order and "may" is running
    using two USB ethernet dongles temporarily while waiting. The majority of internet traffic has been moved over to "alice".

    As for my problem with "alice"... Gone :-) - so "may" was the culprit and no amount of work on "alice" would have fixed it...

    BTW "alice" was my maternal grandmother and "may" her twin sister...

    not worry about the rsync getting interrupted as it might in an ssh session.

    Use the "screen" utility from ssh for such long-running programs. You can disconnect from screen and log out of ssh if you wish. Later log back into ssh if necessary and then connect to screen. Even have multiple "screens" from one ssh session. Less resource intensive than vnc with a gui. Always install this here onto ClearOS here...

    Lots of help for this on the 'web' eg https://www.rackaid.com/blog/linux-screen-tutorial-and-how-to/

  • Great work - thanks.

    Been running 6.9 since May 1 with zero problems...

  • Is it really missing? - An example with permissions

    Reason directories can go missing? Corruption from disk going bad, power-off without proper shutdown, a full partition
    What is the output of "df -Th" ?
    Do the smartctl tests show any disk problems?
    Did you have a power outage?

    Tony Ellis replied to a discussion, What client OS do you use

    Have several clients both windows and linux - but use Fedora 99+% of the time...
    Used gnome 2.x on previous versions - cannot stand gnome 3 - so using the cinnamon desktop
    It's amazing what a modest Ivy Bridge i3 can do - it supports the following without heavy breathing :-

    permanently
    2 displays - a 4:3 and a 9:6
    20 virtual desktops
    18 ssh sessions all logged into various systems
    3 browsers - chrome, firefox and seamonkey - with 54 + web-sites open simultaneously
    thunderbird for mail
    audacious for classical music - work better listening to opera etc
    8+ gkrellm monitors for real-time system status display
    2+ RDP sessions to windows boxes
    1 BoincView running under wine to display the status of all machine running BOINC for World Community Grid
    1 dropbox
    2+ FileMangers
    1 BOINC using all spare cycles for WCG so all CPUs are running at 100% continuously...
    CIFS to connect to server shares
    samba to provides shares for other systems

    ondemand
    video tools for encoding, edits, etc VLC to display
    graphics manipulation tools
    sound manipulation tools and audacity to record
    brasero for DVD burning
    goggle earth
    tigervnc
    pdf tools
    skype
    scp for file transfer
    etc

    Just the usual things, - but NO games... :-)

    Re: How to integrate sarg with clearos community 7

    Nick is correct - if you use the rpm I put together, or my instructions, then sarg will be associated with the standard httpd program and use it's port 80 - not the ports used by webconfig (81 and 82). There are also instructions in that thread to add the requirement for userid/password to access sarg.

    Am testing currently restricting access to sarg via https - but this would still be using the standard httpd program.

    Instructions are also available at http://www.sraellis.tk/master-frame-sargv7.html

    Tony Ellis replied to a discussion, Cant login via Root..

    If you want help - you would be advised to provide more information... have provided a few examples of what is required below...
    There are probably many hundreds of permissions that need to be correct for webconfig to run...

    1) What version of ClearOS?
    2) Where's your screenshot?
    3) Did you change the permissions of files, directories or both?
    4) What were the file/directories you changed? from what? to what?
    5) What were you trying to achieve by making these changes?
    6) Which logs have you checked? What did you find?
    7) What efforts have you made to resolve the problem (other than an incomplete post here)?
    8) Is webconfig running?

    ClearOS did a good job with the 7.3 release - let's hope it goes smoothly for ClearOS 6.9 :)

    Notice a lot of the updated packages are already in the clearos-test repository...
