For a multi-node image cluster on an institute, we have sevaral laptops and machines and we want to create a hadoop cluster with hbase on the top for indexing the data/images.
I have tried some VMare and docker solutions, but the most tutorials are deprecated and very complicated. The sandboxes are not recommended for a productional usage.
I have now, 3 macbook pros with 16gb ram, 2 win pcs with 8gb ram.
I want to take a macbook as a masternode and the other machines as slaves / datanodes.
What’s the best way for us to end up with a cluster where we can read and write very large image files? The cluster will set up in a local network.
Thanks in advice.
I have configure my ubuntu 18-04 with two network card one network card as auto dhcp- for internet and other card with our intranet ip and add this card with a -rout- with gateway of my intranet now the connection is ok but when i restart my system i couldnot access my internet which is configured as auto dhcp, but it is rectified when i off the network-2 (intranet)and then on from network settings menu. please help me to resolve
I am not newbie at exploit development , but I would like to have a solid useful fuzzing framework instead of picking every fuzzing to see if it’s work.. I Have a list of fuzzing framework which I would use in certain cases.
WinAFL,ALF > file format / GUI with reversing(specific target function) Peach , Boofuzz > network protocol
which fuzzer would you recommmend for GUI apps(except webapps) / browsers (TOR,IE,edge , chrome , chromium) ?
I didn’t list spike because the use of Wireshark to find the crash it makes unuseful.
There are many website like https://bitnodes.earn.com/ but I’m failing to understand if they collect nodes from compulsory submission on the web interface for statistics purposes only or they use a way to scan the whole network ?
A second part of the question regarding the type of the node is whether it’s required to run a full node to create blocks as a miner.
When planning to port my application on Oracle to a cloud hosting, I’ve found that one important factor to consider is the volume of data transferred to/from the database, as it is limited by cloud providers. I haven’t found a convenient way to estimate this volume based on usage statistics (e.g. number of queries and average row size), neither how to measure current utilization.
Is there any statistics build into Oracle I could use or it is better to monitor this from the network perspective, monitoring the data transferred to/from the port used by Oracle’s .
I am going to try and configure things correctly to a specific point. Here goes it:
I have a website: https://www.xxxxx-xxxxx.org and I am currently trying to get it to show online and not just on my home network.
I have been to my website provider, i.e. the co. that I purchased this site from currently.
At the provider, I made a CNAME and an A record. I pointed the A record to my IP Address and the CNAME record to my website.
I set up Ubuntu-Server to use the ssh key from a company for https on port 443. I also have this working on my home server/home network but the Apache2 server is not allowing me to view this website outside of my network.
In the router config, I set up Port Forwarding instead of DHCP.
So, this is what is odd to me. Everything works but not on your end. It only works on my end on my network.
P.S. If you need any additional info, although it is frowned up, please contact me.
I have apache2 installed and running correctly. I can see my site online on my network. It is a simple HTML page for now.
/etc/apache2/sites-available/xxxx.xxxx.conf is the file I am in and configuring. This file gives access for me to install my .ca-bundle file, my .key file, and my .crt file. SSL encryption is a big deal these days to me and I would like to figure out how to make Ubuntu-Server work w/ Apache2 and an online website. I have followed all steps in the Ubuntu-Server guide, which can be found here at https://help.ubuntu.com/lts/serverguide/index.html.en, except for the Bind9 section. Should I listen to the steps for Bind9?
An embedded device running Linux version 22.214.171.124, ARM Linux Kernel. Busybox v1.10.2 shell (ash), I’m in Busybox shell. I want to set up connection between embedded device and computer. Is it possible manually set up network connection from Busybox shell? I mounted a main virtual file systems (proc, sysfs, tmpfs, /dev/pts), then entered commands to setup network, but without success. I guess, possibly, some modules or drivers were not loaded in this shell mode, but I’m not sure.

So we all know that NSA has the ability to track down Tor, I2P and all those anonymous networks. I know it’s a piece of old news, but the question always shows up in my mind. Which is why bother it? I mean all your communication is encrypted through public key cryptography even through the simplest HTTPS connection, so apparently, they can’t see what you’re sending through the network. So unless you’re visiting know illegal website, they shouldn’t be able to track you down isn’t it.
Like if you’re talking with your friend through FB’s Messenger, let’s say. There’s so much traffic in and out through FB’s servers, how would they be possible to identify that this traffic is between you and server and then track you down to your location by the IP exploit from the connection (as it’s one of the few stuff that isn’t encrypted).
If that’s true, then why bother if NSA has the ability to de-anonymize Tor network. Or even simpler, why should you use Tor network there isn’t any difference between standard HTTPS anymore? Plus, they still can’t identify you out from that pool of connection through FB server and with a Tor it might even standout from theirs view.
I have no experience configuring network manager by text configs, used only GUI. When moving mouse over NM tray icon there are tooltip “Not connected”, however I see one connection then clicking it – “Wired unmanaged”. Internet working fine.
I make new ethernet connection with priority 10 but it not appear in NM applet menu.
I have change NM config, as suggested in other questions:
Question is: how to connect by new created ethernet connection, or at least make “wired” connection managed?
