Upd Reverse Proxy with iptables DNAT

Sysadmin - 13 hours 7 min ago

Hello, Yesterday I tried to use iptabels to Proxy Udp and tcp Connection. The desired Chain is as following: Client -> eth0 (Server 2) eth1 -> eth1 (Server 1) So the two Servers are connected through a private Networking on eth1 in both ends. I tried:

iptables -t nat -A PREROUTING -p udp --dport 9987 -j DNAT --to-destination eth1(Server 1 IP):9987

iptables -t nat -A POSTROUTING -j MASQUERADE

ipforward is set to 1

But there's no connection. Thanks for help

Show me your gpg.conf / gpg-agent.conf

Command Line - 13 hours 16 min ago

Hi everybody,

I am currently trying to improve my gpg.conf and gpg-agent.conf for that I wanted to have a look at what other people have set.

I'd be happy if some of you could share your configurations or link me to their dotfiles.

Mine are:

gpg.conf:

use-agent utf8-strings auto-key-locate local

gpg-agent.conf:

default-cache-ttl 0 max-cache-ttl 0 pinentry-program /usr/bin/pinentry-x11 allow-loopback-pinentry

X-post gnupg, but I didn't receive any feedback yet.

Help needed. Trying to upgrade Windows 10 Enterprise 1607 to 1709 - Error 0x80070570 - 0x2000c

Sysadmin - 13 hours 33 min ago

Last friday we tried upgrading about 70 Fujitsu Esprimo P756 machines from the Windows 10 Enterprise 1607 Anniversary Update to the 1709 Fall Creators Update. Goal was to find out how long this would take and to measure network traffic and how the network was impacted. While we achieved those goals we also came across a tiny issue ... 4 of those 70 machines failed with an error and then did a rollback to 1607.

Updates and even these feature upgrades get deployed with SCCM.

The SCCM task sequence downloads the image, starts the installation, reboots and the installation gets to 44%. The error we then saw on the screen was "Windows Setup could not configure Windows on this computer’s hardware."

Quite unhelpful.

So I tried installing the upgrade from a modified Windows 10 1709 DVD (read: apps removed). The error I got here was a little more helpful: "0x80070570 - 0x2000c The installation failed in the SAFE_OS phase with an error during APPLY_IMAGE operation."

So I started looking around the internet for tipps on what could be done. And I found what I was looking for. I thought.

  • I ran the Windows memory test to rule out image corruption.
  • --- No errors found. Installation still fails after this.

 

  • I ran "sfc /scannow" and "chkdsk /F"
  • --- No errors found. Installation still fails after this.

 

  • I verified that the cluster size on the local volume is 4096 using the following commands because a number of people claimed that converting their volumes from a cluster size of 512 to a cluster size of 4096 fixed the issue for them
  • --- All our systems are using a cluster size of 4096 already.

    fsutil fsinfo ntfsinfo c:

    Get-WmiObject -Query "SELECT Label, Blocksize, Name FROM Win32_Volume WHERE FileSystem='NTFS'" | Select Label, Blocksize

 

  • I verified BIOS setting to rule out that the harddisk (actually an SSD) was running in RAID mode or whatever.
  • --- Everything configured correctly.

 

  • I ran the driver update tool and updated all drivers, firmware and did a BIOS update.
  • --- The installation still fails.

 

  • I compared the software installed on those 4 machines with each other and with workstations that completed the upgrade successfully.
  • --- I found no single software package that was exclusive to the failing machines. And even uninstalling a few software packages that might cause issues did not help.

 

  • AV on all systems, failing or not is Symantec Endpoint Protection 12.1.6 RU6 MP6 Build 7061
  • --- Since all machines have that installed I have not yet tried to uninstall it on the failing machines.

 

 

So, yeah ... even after trying all the above the installation/deployment of the 1709 upgrade still fails running either a SCCM task sequence or running it straight from DVD.

At this point I'm pretty much out of ideas. Anyone got any that I could still try?

Those of you without SCCM, what do you use for your enterprise AV solution?

Sysadmin - 13 hours 34 min ago

We are currently using Kaspersky for AV and 3rd-party application deployment/patching (ugh!).

I hate Kaspersky Security Center....it's heavy and regularly has clients grinding to a halt so am going to try and convince them to replace it.

I want to try and convince them to start using MDT (with linked deployment shares) to deploy applications but I'm wondering what the overall feeling is for AV solutions?

Possible to setup fake power off using Tasker?

Tasker: Total Automation for Android - 14 hours 14 min ago

Hi, I was wondering whether I could setup a fake power off action using tasker for anti theft reasons. It would basically work like this --> If the power button is long pressed & phone state is unlocked, the regular power menu shows up. But if the power button is long pressed & phone state is locked, a custom power menu shows up(system action blocked), made using Autotools. Pressing on power Off on the custom power menu shows a fake animation screen which says "Powering down" & then turns Off the screen. Then the power button is blocked(so that the screen can't be turned On), either for a short amount of time or is unblocked with some other trigger (like pressing the power button 4 times in a row). I tried using AutoInput to set a trigger when the power button is long pressed, but it didn't work. It seems the power button is protected unlike other physical buttons. How would one go about doing this? I have xposed installed, but would prefer a root only solution.

P.S. I know Cerberus has this feature, but I don't want to pay for a subscription just for this.

Just had the "Open Source is for playing with, not for business" conversation with my boss

What is this, 1997?

This comes about as I'm deploying Moodle for some online training we are doing. Yes, Postgres, Linux, and MySQL -- who really uses that stuff? And yes, Moodle may not match 100% of our requirements in the long run, but which will be cheaper -- hiring someone to write a Moodle extension, or hiring someone to write an entire LMS from scratch?
