Using jmeter non-gui I have a jmx file with this parameter:
<stringProp name="HTTPSampler.domain">172.29.45.119:33187</stringProp>
After finish my test the jml file show:
java.net.URISyntaxException,Non HTTP response message: Malformed IPv6 address at index 8: http://[172.29.45.119:33187]/
Why [] is it added?
Also I have checked to add:
<stringProp name="HTTPSampler.domain">172.29.45.119</stringProp>
<stringProp name="HTTPSampler.port">33187</stringProp>
But It does not work as well
It appears your instance is looking for an IPv6 IP address.
Add this to <jmeter_home>/bin/jmeter file.
Find Variable :
ARGS="$SERVER $DUMP $HEAP $NEW $SURVIVOR $TENURING $PERM $CLASS_UNLOAD"
And add :
-Djava.net.preferIPv4Stack=true
You will get:
ARGS="-Djava.net.preferIPv4Stack=true $SERVER $DUMP $HEAP $NEW $SURVIVOR $TENURING $PERM $CLASS_UNLOAD"

I'm adding Windows firewall rules over PowerShell by taking objects from 3 arrays and filling $Params to issue a New-NetFirewallRule command. I can't figure out why my first command is failing with error "Incorrect port number"
Code:
$All = #( '13.79.172.43' , '13.69.228.5' , '1.1.1.1' )
$AllPorts = #( '8883,443' , '443', '80' )
$AllProtocols = #( 'TCP' , 'TCP', 'TCP' )
for ($i = 0; $i -lt $All.Count; $i++) {
$Params = #{
"DisplayName" = '"Block-WiFi-' + $i
"Name" = 'Block-WiFi-' + $i
"Direction" = 'Inbound'
"InterfaceType" = 'Wireless'
"Action" = 'Block'
"RemoteAddress" = $All[$i]
"LocalPort" = $AllPorts[$i]
"Protocol" = $AllProtocols[$i]
}
# Add Windows Firewall RUle
New-NetFirewallRule #Params
# Check what is going on
Write-Host "Address: $($All[$i]) | Port: $($AllPorts[$i]) | Protocol: $($AllProtocols[$i])"
Write-Host "----------------------------------------------------------------------------------"
Start-Sleep 2
}
So everything is working, except when trying to add first 8883,443 object.
When I try command manually it works:
New-NetFirewallRule -DisplayName "Block-Wireless-In-01" -Name "Block-Wireless-In-01" -Direction Inbound -InterfaceType Wireless -Action Block -RemoteAddress 13.79.172.43 -LocalPort 8883,443 -Protocol TCP
Also when I try to add in #Params "LocalPort" = 8883,443 , the rule is added without errors.
Can anybody help me, cos it driving me crazy for two days already.
Thanks in advance!
Parameter -LocalPort of New-NetFirewallRule is declared as an array String[]. So you have to create a nested array when you want to pass multiple ports:
$AllPorts = #( #('8883', '443'), '443', '80' )
I am looking for a Powershell command that disables DHCP and sets the machine's private IP as a static IP; basically, I'm looking for the Powershell equivalent of following actions in the UI.
Control panel -> Network and Sharing Center -> Ethernet -> Properties -> IPv4 -> Properties -> toggle off "Obtain an IP address automatically" and toggle on "Use the following IP address" -> fill out IPv4 address, default gateway, and subnet mask.
The following commands, taken from this guide, seems to describe what I'm after, but Remove-NetIPAddress results in kicking me off the server and locking me out.
$IP = "10.10.10.10"
$MaskBits = 24 # This means subnet mask = 255.255.255.0
$Gateway = "10.10.10.1"
$Dns = "10.10.10.100"
$IPType = "IPv4"
# Retrieve the network adapter that you want to configure
$adapter = Get-NetAdapter | ? {$_.Status -eq "up"}
# Remove any existing IP, gateway from our ipv4 adapter
If (($adapter | Get-NetIPConfiguration).IPv4Address.IPAddress) {
$adapter | Remove-NetIPAddress -AddressFamily $IPType -Confirm:$false
}
If (($adapter | Get-NetIPConfiguration).Ipv4DefaultGateway) {
$adapter | Remove-NetRoute -AddressFamily $IPType -Confirm:$false
}
# Configure the IP address and default gateway
$adapter | New-NetIPAddress `
-AddressFamily $IPType `
-IPAddress $IP `
-PrefixLength $MaskBits `
-DefaultGateway $Gateway
I'm unable to create a new IPv4 address so long as the existing one is still around, but removing the existing one borks the connection to the server.
That is incorrect. You can set multiple IPs on the same interface. So you simply add the new one with New-NetIPAddress and then remove the previous one.
$currentIP = Get-NetIPAddress | where ipaddress -eq '192.168.43.96'
New-NetIPAddress -InterfaceAlias $currentIP.InterfaceAlias -IPAddress 192.168.43.20 -PrefixLength 24
Remove-NetIPAddress -InterfaceAlias $currentIP.InterfaceAlias -IPAddress $currentIP.IPAddress
The DNS and Gateway are separate things. Just don't change those if you don't need to. To avoid the confirmation prompt, simply add -Confirm:$false to the Remove-NetIPAddress command.
I am trying to set the Azure pipeline variable value in PowerShell. I have created one variable winversion in the Azure pipeline. Now, in a PowerShell task, I want to assign some values to the winversion variable.
My simple question is how can I change the value of an Azure PipeLine variable at run time?
Write-Host "Main value is $winversion"
$env:WINVERSION="abhinav";
Write-Host "Modified value is $env:WINVERSION"
Write-Host "Main value is $(winversion)"
Firstline print: original value is 123
Thirdline Print: Modified value is abhinav
Fourth Line print: 123
I want when I change the value of winversion from "123" to "abhinav" so it actually changes the pipeline variable value to abhinav.
I want to update this variable through Powershell. I am using one PowerShell script calling the API and trying to update its variable but getting the page not found error:-
param(
[string]$winVersion
)
$body = "{ 'definition' : { 'id' :85}
}"
$valueName="Winver"
$definitionId=85
$User=""
$Password=""
$base64authinfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $User, $Password)))
$Uri = "https://Muac.visualstudio.com/OSGCXE/_apis/release/releases?api-version=2.0"
$urlDef = "https://Muac.visualstudio.com/OSGCXE/_apis/release/definitions/" + $definitionId + "?api-version=2.0"
$definition = Invoke-RestMethod -Headers #{Authorization=("Basic {0}" -f $base64authInfo)} -Method Get -Uri $urlDef
#Write-Host $definition
$definition.variables.$valueName.Value = "$winVersion"
$definitionJson = $definition | ConvertTo-Json -Depth 50 -Compress
#Write-Host (ConvertTo-Json $definition -Depth 100)
$update=Invoke-RestMethod -Headers #{Authorization=("Basic {0}" -f $base64authInfo)} -Method Put -Uri $urlDef -Body $definitionJson -ContentType "application/json"
#Write-Host "$update"
#$buildresponse = Invoke-RestMethod -Method Post -ContentType application/json -Uri $Uri -Headers #{Authorization=("Basic {0}" -f $base64authinfo)} -Body $body
#write-Host $buildresponse.status
How To set azure pipeline variable from PowerShell
There is a bit of confusion here, you use the variable $winversion in the powershell scripts, but the variable is set testvar in the pipeline variable.
Anyway, no matter we overwrite the pipeline variable value directly like you, or use the script "##vso[task.setvariable variable=testvar;]testvalue" to overwrite it, the overwrite value only work for current build pipeline. When you use the $(winversion) to get the value, it will still pull the value from pipeline variable value. To get the current value, you need use $env:WINVERSION.
Besides, you said:
I want when I change the value of winversion from "123" to "abhinav"
so it actually changes the pipeline variable value to abhinav.
If you mean you want change the pipeline variable value on the web portal, you need the REST API (Definitions - Update) to update the value of the build pipeline definition variable from a build task.
There is a very similar thread, you can check the answer for the details:
How to modify Azure DevOps release definition variable from a release task?
Note:Change the API to the build definitions:
PUT https://dev.azure.com/{organization}/{project}/_apis/build/definitions/{definitionId}?api-version=5.0
Hope this helps.
I found this link helpful: https://learn.microsoft.com/en-us/azure/devops/pipelines/scripts/logging-commands?view=azure-devops&tabs=powershell
This has the complete options of what you can do:
https://learn.microsoft.com/en-us/azure/devops/pipelines/process/variables?view=azure-devops&tabs=yaml%2Cbatch
You can reuse set variable from task to task, and also job to job.
I couldn't find anything on stage to stage.
In summary:
jobs:
# Set an output variable from job A
- job: A
pool:
vmImage: 'vs2017-win2016'
steps:
- powershell: echo "##vso[task.setvariable variable=myOutputVar;isOutput=true]this is the value"
name: setvarStep
- script: echo $(setvarStep.myOutputVar)
name: echovar
# Map the variable into job B
- job: B
dependsOn: A
pool:
vmImage: 'ubuntu-16.04'
variables:
myVarFromJobA: $[ dependencies.A.outputs['setvarStep.myOutputVar'] ] # map in the variable
# remember, expressions require single quotes
steps:
- script: echo $(myVarFromJobA)
name: echovar
Apple removed high-level PPTP support in macOS Sierra from its network configuration system. However, the PPP internals are all still there, including /usr/sbin/pppd and /etc/ppp/.
How can I programmatically initiate a PPTP VPN connection on macOS Sierra / High Sierra using what's left?
Answer:
This method creates a PPTP connection that doesn't send all traffic and doesn't override other DNS providers, meaning it works with multiple simultaneous VPN connections each having different DNS search domains, and closes it in an orderly fashion.
Not sending all traffic requires you to know the VPN subnet beforehand. If you don't, you must send all traffic (see below), since vanilla PPP/LCP has no means to tell the client its subnet (although theoretically the ip-up and ip-down scripts could guess it from the received IP address).
Save this perl as /usr/local/bin/pptp:
#!/usr/bin/env perl
if (#ARGV) {
my $name = $ARGV[0];
if (length $name && -e "/etc/ppp/peers/$name") {
my $pid;
$SIG{"INT"} = "IGNORE";
die "fork: $!" unless defined ($pid = fork);
if ($pid) { # parent
$SIG{"INT"} = sub {
kill HUP => $pid;
};
wait;
exit;
} else { #child
$SIG{"INT"} = "DEFAULT";
exec "pppd", "call", $name;
exit;
}
} else {
print "Error: PPTP name: $name\n";
}
} else {
opendir my $d, "/etc/ppp/peers" or die "Cannot read /etc/ppp/peers";
while (readdir $d) {
print "$_\n" if !($_ eq "." || $_ eq "..");
}
closedir $d;
}
Run it as sudo pptp AcmeOffice, where AcmeOffice is the PPP connection name, and close it with a single Control-C/SIGINT.
In /etc/ppp/peers, create the PPP connection file, in this example /etc/ppp/peers/AcmeOffice:
plugin /System/Library/SystemConfiguration/PPPController.bundle/Contents/PlugIns/PPPDialogs.ppp
plugin PPTP.ppp
noauth
# debug
redialcount 1
redialtimer 5
idle 1800
#mru 1320
mtu 1320

novj 0:0
ipcp-accept-local
ipcp-accept-remote
refuse-pap

#refuse-chap-md5

# usepeerdns
noipdefault
# logfile /tmp/ppp.AcmeOffice.log
ipparam AcmeOffice
remoteaddress office.acme.com
user misteracme
password acme1234
The last 4 options are connection-specific. Note the password is stored cleartext. chown root:wheel and chmod 600 is recommended. nodetach, ipcp-accept-local, ipcp-accept-remote, noipdefault are critical.
Since we're not becoming/replacing the default route, you must manually change your routing table. Add an AcmeOffice entry to the /etc/ppp/ip-up script:
#!/bin/sh
#params: interface-name tty-device speed local-IP-address remote-IP-address ipparam
PATH=$PATH:/sbin:/usr/sbin
case "$6" in
AcmeOffice)
route -n add -net 192.168.1.0/24 -interface "$1"
;;
AcmeLab)
route -n add -net 192.168.2.0/24 -interface "$1"
;;
AcmeOffshore)
route -n add -net 192.168.3.0/24 -interface "$1"
;;
VPNBook)
;;
*)
;;
esac
and your /etc/ppp/ip-down script:
#!/bin/sh
#params: interface-name tty-device speed local-IP-address remote-IP-address ipparam
PATH=$PATH:/sbin:/usr/sbin
case "$6" in
AcmeOffice)
route -n delete -net 192.168.1.0/24 -interface "$1"
;;
AcmeLab)
route -n delete -net 192.168.2.0/24 -interface "$1"
;;
AcmeOffshore)
route -n delete -net 192.168.3.0/24 -interface "$1"
;;
VPNBook)
;;
*)
;;
esac
If the VPN has a DNS search domain (i.e. somehost.office.acme.com), create a file in /etc/resolver/ named after the DNS suffix, like /etc/resolver/office.acme.com, with contents like:
nameserver 192.168.1.1
domain office.acme.com
Note that this requires knowing the destination domain & nameserver beforehand. Theoretically ip-up & ip-down could create & delete this file on demand.
To send all traffic (& if you don't know the destination subnet), uncomment #defaultroute in the PPP connection file and leave the ip-up & ip-down entries blank (e.g. the VPNBook example). To override your DNS with the VPN's, uncomment usepeerdns.
I have to make a script in shell and PowerShell that shortens ipv6 addresses as much as possible.
Like:
Input: 2001:0db8:03cd:0000:0000:ef45:0006:0123
Output: 2001:db8:3cd:::ef45:6:123
And the script should give a description of itself if -help parameter used but i dont know how to do that in PowerShell.
This is my code in PowerShell, it shortens the addresses correctly:
param([parameter(Mandatory=$true)]$file)
if (test-path $file){
foreach ($ip in Get-Content $file){
$ip=$ip.Replace("0000","")
Write-Host $ip
}
}
I have no idea how to do the shortening in shell, I tried like this but didn't work:
#!/bin/sh
if [ $1 = "-help" ]
then
echo description
else file = $1
fi
for ip in `cat ipv6.txt`
do
$ip=$line
$replace=""
$echo ${var//0000/$replace}
done
This is the txt file with the addresses:
http://uptobox.com/6woujdvdfkmh
The beauty of PowerShell is that you have access to a rich library that has methods for doing this for you. Try this:
<#
.SYNOPSIS
Converts long form IP address into its short form
.DESCRIPTION
Converts long form IP address into its short form
.PARAMETER IPAddress
The IP address to convert.
.EXAMPLE
PS C:\> ConvertTo-IPAddressCompressedForm 2001:0db8:03cd:0000:0000:ef45:0006:0123
#>
function ConvertTo-IPAddressCompressedForm($IPAddress) {
[System.Net.IPAddress]::Parse($IPAddress).IPAddressToString
}
C:\> ConvertTo-IPAddressCompressedForm 2001:0db8:03cd:0000:0000:ef45:0006:0123
2001:db8:3cd::ef45:6:123
Note that to get usage in PowerShell based on the doc comments use:
ConvertTo-IPAddressCompressedForm -?
We might be going to the same school. This is what I was told to do and it works perfectly:
cat filename | sed -e 's/:0*/:/g' filename
$longIPAddress = '2001:0db8:03cd:0000:0000:ef45:0006:0123'
$shortIPAddress = ([IPAddress]$longIPAddress).IPAddressToString
$shortIPAddress
2001:db8:3cd::ef45:6:123
