Question on server/network infrastructure for CAD Programs.

Sysadmin - 1 hour 2 min ago

Hello All,

I'm looking for some help regarding the topic I posed in the title of this thread. I'm a CAD Manager for AutoCAD Civil 3D in an engineering firm that has several offices and while I understand quite a lot about computers and IT problems, I still don't have the background knowledge to understand everything about servers and typical workflows/setups for companies like mine.

The company brought me on to upgrade their CAD Standards, Monitor their software and upgrade their Computers because they were antiquated and inefficient. While here, I've noticed several issues with how IT handles and sets up computers and software that negatively affect performance of my CAD users. Currently I'm pushing for more power in the process of software/computer selection but it seems that our IT Manager doesn't actually understand the application of his choices and its affects. An easy example I can give is downloading windows 10 on computers that are running programs that become greatly bugged by windows 10. He also suggests that users never restart or turn off their computers or do anything with file management or anything else. Before I arrived, the computers he was purchasing for HEAVY CAD users were just the bare minimum spec recommended by the product manufacturer and he had no actual insight in workflow or actual computing requirements for large and complicated files. His background is unorthodox in IT and I believe he doesn't actually understand how computers read and process information.

My problem is that I believe our current solution towards working on projects between offices is negatively affecting performance. Currently, my company uses Amazon Web Services with a Nasuni cloud server that communicates with remote filers in each office. The way I understand it is that if a person opens a file in office 1, the filer will communicate with the Nasuni server which then communicates to the filer in office 2 to lock the file. I'm unsure of what is a typical solution and while I believe this solution is alright, I'm unsure of how AWS affects the files and latency. I'm also unsure of why we get intermittent disconnections throughout the day and why typical 1-3 minute loads are considered okay but no one seems to bat an eye here. To give you an idea, the typical loads for small 1-2mb files were about 5-10 minutes before I arrived and fixed registry issues in our computers and cleaned up the filing system and more.

TLDR: Basically, I sense there is still an issue with how IT has set-up everything because I've never experienced this type of lag at any company in the past and many of my coworkers who are computer literate agree. However, I don't have the background to make a great judgement.

Any help at all would be wonderful and I'm happy to answer questions for clarification. Thank you so much!

Looking for resources to become more familiar with terminology and concepts.

Command Line - 1 hour 17 min ago

So I am more or less a complete beginner when it comes to anything command line. I just really understood what a "shell" even is earlier today. I am finding it hard to keep all the different aspects of this topic straight. For example, I have been googling definitions for: shell, git, git bash, MinGW, powerShell, command line, etc. As well as trying to learn the basics of Linux/Unix environments. Basically, I don't know how to keep anything straight in my head, and haven't drawn the "mental borders" so to speak, for each concept. Does anyone know of any good resources that compile a lot of this knowledge/info? I have been doing my due diligence in reading and researching myself, but I've come to the point where each search leads to 3 more, and so on.

Any stories of your personal journeys in this field would also be appreciated! It just feels so binary from my perspective, like people already know everything or they know nothing. Just trying to break through!

winbind or sssd for Samba AD member and why?

So, I am going to implement a Samba AD DC server. We also have a handful of Samba file servers which are going to be AD member servers.

The Samba wiki still say, you should use winbind for auth stuff against AD. But I heard from several sources, that the cool kids are using sssd nowadays.

Why is that? And do I have stable uid/gid mapping across the entire domain (we going to use RFC2307)? I heard, that id mapping can be messy with sssd.

Or should I use winbind for stability reasons?

Recommendations for affordable hardware firewall with threat/malware detection?

Sysadmin - 1 hour 34 min ago

Hi guys,

I'm looking for an affordable hardware firewall with threat/malware detection and preferrably IPsec VPN capabilities.

Something like Cyberoam/Sophos is perfect. I'm just curious if there are any cheaper alternatives as this is a very small business with not a lot of requirements.

Anyone have any recommendations? They'd be very much appreciated!

Moving Folder Redirection to new target, cotchas?

Sysadmin - 2 hours 16 min ago

Following scenario:

Users at a remote office have a folder redirection for personal files to an old ass file-server (Server 2003 R2). I prepared a new server and I'm ready to make the switch.

The redirection target is \\\dfs\userfiles

What I plan to do is add the new server in the dfs target, disable the old dfs target and hope for the best.

The files are already all copied over and permissions are identical. The old server is also still operational.

Successful outsourcing transition

Sysadmin - 3 hours 51 min ago

I am looking for tips on transitioning from in house to offshore system administrators.

My thought is to give the current sysadmins a choice between immediate dismissal or signing a contract to train the offshore sysadmins for a period of 3 months.

What stipulations are good to put in the contract to ensure their compliance?

My friend suggested we hire off-duty sherriff's deputies to be in the room when we inform the current sysadmins of the situation in order to prevent any unpleasantness.

What's the best way to ensure they realize there is no choice but compliance? I want to make sure the transition goes as smoothly as possible without incident.

Question on PCI-DSS compliance

Sysadmin - 4 hours 21 min ago


I have a customer that owns a brick and mortar store. They accept credit card, debit card, cash, and check as payment for services. They have ERP/LoB software that handles EVERYTHING about their business from inventory to record keeping to payments/checkout.

Here are some things they are doing that are probably bad

  1. Generic AD account to login to the three PoS computers. HOWEVER , the LoB software has a unique username/password specific to each employee. Card transactions cannot be processed without opening this software which requires unique creds

  2. Storing almost complete cardholder details in a variety of ways for recurring billing. They have a customer fill out a paper form which includes full card number, name on card, and billing ZIP code. They do NOT record CVV or CVV2 as far as I'm aware. They then take this paper form and scan it into a publicly available scans folder (available to AD\Domain Users). They then login to the LoB software and attach that scanned document to the customer's account within the LoB software. From then on, it disappears from the shared folder and requires login to the LoB software to view.

  3. The paper copies are sometimes shredded after scanning and sometimes placed in a folder somewhere or sometimes simply misplaced somewhere in the facility

  4. When it comes time to make a recurring payment on behalf of a customer, an employee will open the attachment after logging into the LoB software, read the card details, and then grab one of USB payment terminals (Verifone VX 805 maybe? Can't recall) that's attached to their computer and manually key in the card information to process the transaction. Normally, when a customer is in person, they are also required to sign the digital signature pad, so it's unclear to me how this card not present transaction is completed without this.

  5. Paper or Electronic receipts are offered to customers. These only include the last 4 digits of the card number.

In the past, they've been told that they only have to comply with PCI SAQ C, but reading it, I found that SAQ C only applies under the following:

-The payment application/Internet device is not connected to any other systems within your environment not the case; the computers are fully networked with all other on-prem systems

-Your company retains only paper reports or paper copies of receipts not true, electronic receipts are available and sent via email to customers sometimes

  • Your company does not store cardholder data in electronic format; not true, cardholder data is sometimes stored

As the technology consultant, I have not been specifically tasked with maintaining PCI-DSS compliance, but I have a feeling that if the **** hits the fan, they'd blame me for being non-compliant and getting massive fines.

In my case, what would you do?

Building python 2.7 on Cent 6.9

I am experiencing a frustrating problem. I am building python 2.7 (as an altinstall of 2.6 which is staying in place) on Centos/RHEL 6.9.

To make things difficult the install image is minimal and the system is air gapped.

The problem is getting zlib to work properly. Trying to build zlib from the modules directory fails the python build. If I install the 64bit (or 32 bit) devel rpm then it fails to build the python zlib module.

Anyone have luck doing this or know what I'm missing?

Ellucian's Banner

Sysadmin - 4 hours 49 min ago

Is there any admins out there that has experience with Ellucian's Banner? I am the Senior Admin at a HBC and we have various money issues and this is causing us major problems. I am not versed in this and no one else on staff is either; I just started a month ago with the school. But I am not an sql admin. I can do RHL on which this installation is based but we are being held hostage by the past manager of this (she did freelance work for us on Banner, since we owe Ellucian money). I get why shes doing this, but it is hindering our school on a massive level. Does any one have any advice. Here are my questions. Does anyone know of any SRBs that are cheaper and have worked for you and your campus? What options do we have to try and recoup our login from the contract worker who is holding it hostage? Has anyone dealt with Ellucian before and what was that like? Especially regarding monetary issues? I am sure I have more but it is 6am and my mind is not at full speed yet, lol. I suppose I am just wanting any advice on this anyone has. Thank you in advance for any help!

[question] Remote and console shutdown is failing on 2008 R2 box after ESXi upgrade

Sysadmin - 5 hours 20 min ago

Virtualization team just completed upgrade to 6.5 and now one of the guest VM's will simply not shut down.

  • RDP does not work

  • From VMWare console session, Ctrl+Alt+Delete will not take (tried multiple browsers from multiple machines to rule out client side)

  • Remote powershell sessions connect, able to stop processes but "Restart-Computer" just hangs

  • Psexec works, shutdown.exe /r just hangs, also tried with SYSTEM and highest privileges flag

  • Shutdown /m \<server> also just hangs
    After entering the shutdown commands the cursor just moves to the next line and hangs, for at least an hour so far

From vmware, it looks like the tools upgrade process may have failed, graceful Shutdown and Restart buttons are greyed out. Even a Reset fails with "Another task is already in progress"

The absolute last thing I can even think of trying is to kill some critical processes with taskkill which seems to work or even try the Terminate() method from Win32_Process..

If that fails I am completely at a loss.

Any other ideas to restart from either the OS or hypervisor level?

Texpad 1.8.4 - LaTeX editor.

MacUpdate - Mac OS X - 5 hours 45 min ago

Texpad is a LaTeX editor designed for straightforward navigation of projects of any size. When Texpad opens a document it scans through it, looking for LaTeX structure commands and any included files, then it presents you with an outline view with which you can swiftly navigate the entire project.

Texpad replaces LaTeX's obscure console output with a table of typesetting errors. Clicking on these errors will direct you to the offending line in the LaTeX source.

Texpad's elegant single window design saves you from the clutter of windows. In even the largest projects all files are accessible from the outline view to the left of the editor. This one-window design works especially well with OS X 10.7 Lion's fullscreen mode.

Version 1.8.4:
  • Duplicate option
    • Single file Duplicate under the file menu has been restored
    • Duplicate entire project option has been added
  • Global Search
    • There is now a Case sensitivity option for Global Search, normal and Regular Expressions under the search menu accessed by clicking the magnifying glass.
    • A Regular Expression option has been moved to the search menu. You can no longer trigger Regular Expression search with enclosing slashes, you must use the menu. This is necessary because it now allows users to search for terms such as /$/ without accidentally triggering regular expression search.
  • TexpadTeX packages can automatically download when required. There is a permission option on the TexpadTeX bundle manager screen to allow this. You will be prompted the first time to do this.
  • Minor enhancements
    • Cleaned up 1.7 era files from the App Support folder
    • Find bar in the editor now shows the result count
    • Organiser file icons have been improved
    • Right-click/context menu in typeset issues list now allows copy to clipboard
    • Added an option to export .bbl (and other intermediate files) when using TexpadTeX
    • The active build script is now displayed on the typeset bar
    • Added a setting to choose whether or not to jump to errors post-typeset
    • Pressing Escape in the global text and tag search fields will now shift focus to the editor
    • Up and down arrows keys will now navigate through the tag search table
  • Fix for
    • Issue where PDF pages could end up out of order in the viewer
    • Incomplete info view for citations in the autocomplete windows
    • synctex command with TexpadTeX
    • Fix for Jump’ button in autocomplete popover
    • Autosense with gastex and a number of LuaTeX specific commands
    • TexpadTeX to turn off with the nomencl and mtpro2 packages
    • Crash when importing projects to Texpad Connect with non-local documents
    • TexpadTeX search paths
    • Global build scripts list in the typeset config window
    • TexpadTeX retypesets after a bundle is installed
    • App-wide auto-typeset setting used with external typesetter
    • Export project as folder to use relative, rather than absolute, paths
    • Remote connect project creation notification
    • Autofill with Bibtex files that have an escaped close curly bracket in the bibtex entry
    • Issue with connect where it could lockup when opening a tpc document with wifi connected, but no connection to server possible
    • CMD-T with TexpadTeX in an unsaved file

  • OS X 10.11 or later
  • For typesetting user must have a LaTeX distribution installed. MacTeX is available for free.

Any SPLA (US) pros out there?

Sysadmin - 6 hours 49 min ago

we have 2 servers that are 2012 datacenter. We currently license 4 CPUs (processors) for ~$120 each cpu per month. Or a total of about $5800 per year per server.

I am told that going to 2016 this would now cost 2 *16 core licenses (~$6k) per server so ~$12000 per year per server. Is this possible?

this does not seem right.
