I am using arango-single-server on minikube. Installed using kubectl by following: https://www.arangodb.com/docs/stable/tutorials-kubernetes.html
Following the error message:
➜ kubectl exec -it arango-single-server-sngl-d0leq3in-d9649f -- arangosh --server.endpoint "tcp://localhost:8529" --server.database "_system"

Any idea, what is the issue ?
I can access the gui interface.
It works by putting --server.endpoint "https://localhost:8529" or --server.endpoint "http+ssl://localhost:8529" instead of --server.endpoint "tcp://localhost:8529"
I got help from https://www.arangodb.com/docs/stable/programs-arangosh-examples.html

I installed scapy 2.4.5 and am running this code by Python 3.10.1 on M1 Mac.
Any ideas?
I was able to solve this by installing the optional libpcap library that Scapy mentions in its installation documentation.
Run brew update in your terminal
Run brew install libpcap in your terminal
Run Scapy with scapy in your terminal
Within Scapy run conf.use_pcap = True
Here's the link to the documentation with more info
For reference I am running an M1 MacBook Air (macOS Monterey v12.1) with python 3.8.12.
I got the same error on a M1 MacBook and I solved this by installing and configuring libpcap as #RBPEDIIIAL suggested.
I am running jmeter in non GUI mode in my linux server inside docker. When I check jmeter is installed or not it says its there with the version but when I execute my script it says as follows-

I experienced that also. In my case, the problem was the path set on JMeter component “CSV Data Set Config”. When I executed the project at my machine, the Jmeter searched and found the path, but after upload to the server I forgot to change the CSV path according to the server environment. After change it the tests were executed Ok on server. So, check if there is something like that on your JMeter project.
im very new with arango, but when i try to start the server with arangosh i get this

Pretty printing values.
Could not connect to endpoint 'http+tcp://127.0.0.1:8529', database: '_system', username: 'root'
Error message: 'Could not connect to 'http+tcp://127.0.0.1:8529' 'connect() failed with #61 - Connection refused''
using the newest version
It looks like the arangod server is not running on the same machine (127.0.0.1) on port 8529.
Can you verify it is actually running, and its port number is actually 8529? This is the default port, but it can be adjusted in the server configuration file (arangod.conf).
This error occured because arangoDB server is not running. In macOS You have to start server by running this command.
/usr/local/sbin/arangod &.
On Debian 8 Linux, I use vim together with screen to send lines from vim to a julia session. Today, I tried https://github.com/Keno/Cxx.jl. I followed the instructions there (i.e. I compiled the latest version 0.5.0-dev+3609 of Julia). The following bug appeared when I tried example 1, I could pinpoint it to the following simple steps:
Create the following files (don't overwrite your own files):
printf "using Cxx\ncxx\"\"\"#include<iostream> \"\"\"\ncxx\"\"\"void testfunction(){std::cout<<\"worked\"<< std::endl;}\"\"\"\njulia_function() = #cxx testfunction()\n" > start
and printf "julia_function()\n" > freeze
Open terminal 1 (I use gnome-terminal) and write screen -S session and then start Julia with julia. It should look like

Open terminal 2 and do
screen -S session -p 0 -X eval "readreg p start" "paste p" Terminal 1 should now look like

true
julia> julia_function() = #cxx testfunction()
julia_function (generic function with 1 method)
julia>
Now the strange bug appears: writing "ju", using TAB to complete to "julia_function" and adding "()" by hand in terminal 1 leads to
julia> julia_function()
worked
julia>
But if I do steps 1, 2, 3 and then screen -S session -p 0 -X eval "readreg p freeze" "paste p" in terminal 2 or write julia_function() in terminal 1 without using TAB to complete then I get a freeze in terminal 1:
julia> julia_function()
If I do steps 1, 2, 3, use TAB completion as described above, then (i.e. after the first call, which compiles the function) screen -S session -p 0 -X eval "readreg p freeze" "paste p" in terminal 2 and julia_function() without using TAB in terminal 1 work as expected (it prints "worked") and don't cause a freeze.
If I do not use screen at all, it works (with and without TAB). Can you please tell me what is going on here?
I downloaded a font from FontSpace.com
and unzipped it using unzip my_font.zip
The following was then printed:

How was this achieved? I don't mean the unzipping, I mean the printing of the advertisement.
On the command line you can do this with command zipnote which generally comes with the zip command.
From the manpage:
Example:
zipnote foo.zip > foo.tmp
ed foo.tmp
... then you edit the comments, save, and exit ...
zipnote -w foo.zip < foo.tmp
The trick is to put the "comment" at the end of that .tmp file that is read back into the .zip by the zipnote command.
