I am using a server 1GB ram machine server, 1 core processor (as a set up, the free tier instance on AWS) to serve API REST GET requests that occasionally compute sub-graphs and matrixes on demand using scientific python modules. I want to expand web service on a larger machine, to host more datasets: I look for a cheeper solution with no need to oversize the machine. I am helping myself with benchmarking sites [e.g. http://serverbear.com] to compare server types, but I don't have expertise in making a decision between type of VPS, cloud, dedicated, IO server and technical features. Could you help in selecting server type requirements to compute graphs / matrixes on spot and serve extracted ...

I was given a Techus N7700PRO with 7 x 1TB WD Caviar Blue drives in it all in healthy condition. Crazy good score, right? Problem is I've never setup a NAS before and I basically want to make myself a redundant cloud storage device out of it. I also don't want it ruing 24/7 and would like to setup a Wake-on-LAN feature (if that's what that does). I also need to reformat all the drives and delete any old files off of them. I've installed the utility and can access the NAS from my desktop, just don't know where to go from here. So how do I wipe, reset, and setup my redundant cloud storage to be accessed from anywhere and get a power setting schedule or wake-on-lan feature setup? Thank you -G L...

I have set up a lab server with W2016TP5, and it runs (more or less) fine. The static IP and subnet seem correct, and the DNS and DHCP servers and a bunch of Hyper-V linux VMs seem to be all fine. However, the taskbar shows permanently a "network broken" sign (see picture). Ruing the windows diagnostics does not identify anything wrong. Ipconfig yields the following: Etheet adapter vEtheet (ExtealTo02): Coection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : fe80::f142:1a28:5a28:9821%24 IPv4 Address. . . . . . . . . . . : 10.10.10.2 Subnet Mask . . . . . . . . . . . : 255.255.0.0 Default Gateway . . . . . . . . . : 10.10.10.1 Tuel adapter Local Area Coection* 2: Coection-specifi...

I'm using wpa_supplicant with comand over Centos 7. When I start wpa_supplicant either as system service or manually, and with debug enabled, wpa_supplicant list all BSSID near my computer. Then, after a while, wpa_supplicant remove, unilaterally, all networks listed. How I can avoid this behaviour? I have compiled my own version of wpa_supplicant and this behaviour is also reproducible in it. This is my configuration file: ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=wheel The command line configured in system service is the following: /usr/sbin/wpa_supplicant -u -ddt -f /var/log/wpa_supplicant.log -c /etc/wpa_supplicant/wpa_supplicant.conf $INTERFACES $DRIVERS $OTHER_ARGS An...

I changed gateway ip on tablet to be 192.168.1.16 tried, and inteet didnt work. then I tued on ip forwarding on ubuntuecho 1 > /proc/sys/net/ipv4/ip_forward tried, nothing worked again.

I have two laptops, one ruing windows 7 and the other ruing ubuntu. I am using company wifi which I can coect only one device at a time.I set up a hostednetwork on the windows laptop (using netsh wlan ... ) and coected my ubuntu laptop to it with no glitches.This was yesterday. Today when I tried to coect again, the ubuntu laptop keeps trying to coect (the wifi symbol keeps animating) and doesn't coect to the network. I tried setting up a different network, removing the old one. I tried using virtualwifihotspot tool, but no results. What might be the problem? Let's block ads! بخوانید...

Hello, I have two wireless routers configured properly following my Inteet Service Povider instructions. Our house is composed of two floors and in each floor there is an ADSL socket, to which is coected each of my two routers (using ADSL filters). My problem is that i can't get the two routers to work at the same time. In order for one of them to work properly and coect me to the inteet , the other one should be shut down. So, is there any kind of configuration that could be made in order to get the two routers to work properly at the same time? N.B: The two routers are separated by distance and caot be linked to each other (LAN-to-LAN or Lan-to-WAN). Thanks in advance Let's block ads! بخوا...

The problem setting involves 4 devices: I have tried the usual uninstall everything and system restart including all system USB controller drivers. When I plug the Fulla into the Anker USB hub, the device is not recognized. When I plug it directly into the Das Keyboard or the X1 Carbon laptop, the Schiit Fulla USB 2.0 DAC amp works. This leads me to believe that the Anker USB hub is the problem. However, the Das Keyboard is plugged into 2 ports in the Anker USB hub. So I tried to coect the Schiit Fulla with a Y cable to give it an extra boost if power was the issue and get a “Unrecognized device” in device manager. Lenovo Laptop -> Anker USB 3.0 Hub -> Das Keyboard with built-in 2.0 hub -> F...

Have a mostly Ruckus AP wifi environment outside the US. Having issues with our Motorola ET1 staying coected after going to sleep, (we have similar setup in other Ruckus environments with no issues). Comparing this environment with a similar Ruckus setup without the wifi drop issues, a network engineer suggested that maybe enabling 802.11d on the switches could help. Could having a US device with 802.11d enabled, on a network with 802.11d disabled cause coectivity issues? If so, could you explain why? Let's block ads! بخوانید...

I have been using just a standard foreach loop, which executes as it should. However, I have an 8 core processor and 16GB of RAM and thought I would utilize such with a Parallel.foreach loop.

I'm trying to share my Inteet Coection with another system over Windows ICS. My system coects to the Inteet via WiFi and shares it over to another system over LAN. This works perfectly without any issues. (Yes, I know, it's not a usual situation) But, I need to add proxy settings in the middle to that I can see all the traffic as well as block some of it before it gets to the ICS client. Say, I coect to the Inteet using Wireless Adapter 1, and then I use Windows Inteet Coection Sharing to serve inteet over Local Area Coection 1. I need to add a proxy only to traffic that goes through the Local Area Coection 1, that is only the data used by the ICS client. Any help is appreciated, TIA! Let's ...

for a colleague I have created a zip containing two projects, each having multiple docker images that are compressed to xx.tar inside them. The idea is that I can give her a zip file of the whole folder. She then extracts this which should result in the following structure: folder ├─project1 │ ├─docker1.tar │ └─docker2.tar └─project2 └─docker3.tar I am creating this zip using zip -er folder.zip folder on my mac. other unix and mac users have no problems with this but the windows users complain that there is not enough space on the drive, it requires 785PB(!) to extract.. what I can see is when I browse the zip on the windows machine is that it says the size of one of the .tar files is 785 PB...

On my windows laptop I get the following message when trying to login: "the trust relationship between this workstation and the primary domain failed" According to Microsoft I should rejoin the domain - requiring a local admin account. But since, I do not know what local accounts are on the laptop I decided to use a password reset tool. So I downloaded a bootable USB image from pogostick.net/~pnh/ntpasswd. The boot process however fails with keel panic: Booting … Decompressing Linux … Parsing ELF … done Keel panic - not synching: No init found. Try passing init = option to keel System: Lenovo T450s, CPU i5 5th generation. Any Idea how to fix it or what other tool works fine? Let's block ads!...

In Windows, there's something called the servicing stack which seems to fulfill the role of a package manager. I don't understand it very well, only that it seems that Component-Based Servicing (CBS), Windows Installer, Windows Update, and WinSxS are part of the servicing stack or are otherwise involved in servicing. I've done lots of research and have not been able to find an easy-to-understand overview on servicing in Windows. Hence, I'm asking the following: What is servicing and what does the servicing stack do? How does the servicing stack work? What roles do CBS, Windows Installer, WinSxS, and Windows Update play? What utilities does Windows provide for interacting with the servicing s...
