When I try and set up my DNS server to use dns2tcp using sudo dns2tcpd -F -d 3 -f ~/etc/dns2tcpdrc.conf I get the error Error socket.c:107 bind error
How do I fix this?
something running in port 53 . to find use sudo netstat -anp | grep :53
Then use kill PID

I've got kali linux from microsoft store.
I wanted to run ./ngrok authtoken <my_authtoken>
but got -bash: ./ngrok: cannot execute binary file: Exec format error
so I tried chmod +x ./ngrok authtoken <my_authtoken> and sudo chmod +x ./ngrok authtoken <my_authtoken>
but either way I get chmod: cannot access 'authtoken': No such file or directory chmod: cannot access '<my_authtoken>'
what should I do?
I really need to run ./ngrok authtoken <my_authtoken>
P.S: I want to use blackeye and when I chose the number it downloaded Ngrok
edit 1: I downloaded another version from https://ngrok.com/download and I removed the previous Ngrok in blackeye directory and unziped the new one instead.
now I'm getting bash: ./ngrok: Permission denied
edit 2: It's been 12 days with no accurate answer guess I gotta get the real Kali Linux and the problem is the windows version.
Always Google and try to find an answer before you post a question.
Your first error (-bash: ./ngrok: cannot execute binary file: Exec format error) is probably because your trying to run a program made for a different architecture such as x86 or ARM (see https://askubuntu.com/a/648558).
Your second error (chmod: cannot access 'authtoken': No such file or directory chmod: cannot access '<my_authtoken>') is because your trying to run a command from within chmod, you have to chmod the file then run it.
Your third error (bash: ./ngrok: Permission denied) is because you need to chmod the file to an executable before you can run it, and there is no need for sudo unless chmod returns chmod: cannot access '<yourfile>': Permission denied then you should use sudo.
What your should run is:
curl -L https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip -o ngrok.zip
unzip ngrok.zip
chmod +x ngrok
./ngrok authtoken <myauthtoken>
this was the only thing that work for me:
curl -s https://ngrok-agent.s3.amazonaws.com/ngrok.asc | sudo tee /etc/apt/trusted.gpg.d/ngrok.asc >/dev/null && echo "deb https://ngrok-agent.s3.amazonaws.com buster main" | sudo tee /etc/apt/sources.list.d/ngrok.list && sudo apt update && sudo apt install ngrok
I'm really new to Docker. I'm trying to run Wordpress, and I've run into an error.
$ docker-compose up -d
testpublichtml_mariadb_1 is up-to-date

My guess is to try and check if something is on port 80, though I'm not sure how to check that.
When I enter netstat -tulnp | grep ':80', I get:
$ netstat -tulnp | grep ':80'
netstat: option requires an argument -- p
Usage: netstat [-AaLlnW] [-f address_family | -p protocol]
netstat [-gilns] [-f address_family]
netstat -i | -I interface [-w wait] [-abdgRtS]
netstat -s [-s] [-f address_family | -p protocol] [-w wait]
netstat -i | -I interface -s [-f address_family | -p protocol]
netstat -m [-m]
netstat -r [-Aaln] [-f address_family]
netstat -rs [-s]
Probably you have some service running on port 80. To check this, execute the following command.
netstat -tulnp | grep ':80'
The last column is PID/Program name of your process. If you want to kill it, use the following command.
kill PID
After that, you should be able to start your container.
Given the following code
pingval=$(ping6 -c 1 "$url")
time=$($pingval| tail -1| awk '{print $4}'|cut -d '/' -f 2)
Could anyone tell me why I'm receiving a PING: command not found error?
My solution to this was to simply use
time=$(echo pingval|......)
I'm presuming you're wrapping this in a shell script? Is the ping6 command in the search path for the shell you're using to execute that script?
Also, stating the obvious: ping6 is also in your path?
which ping6
I need to identify a daemon process that is writing to a log file periodically. The problem is that I dont have any idea which process is doing the job, and I need to show some progress to the client by tomorrow. Anybody has any clue?
I have already sorted out the daemon processes running in the system with the help of the PPID. Any help would be appreciated.
Also I think it is possible (rarely) for a daemon not to have a PPID as 1. How can we find it out then?
Try the fuser command on your log file, which will display the PIDs of processes using it.
Example:
$ fuser file.log
file.log: 3065
lsof gives a list of open files with the processes.
So lsof | grep <filename> should help you.
You can use auditctl.
# sudo apt-get install auditd
# sudo /sbin/auditctl -w /path/to/file -p war -k hosts-file
-w watch /etc/hosts
-p warx watch for write, attribute change, execute or read events
-k hosts-file is a search key.
# sudo /sbin/ausearch -f /path/to/file | more
Gives output such as
type=UNKNOWN[1327] msg=audit(1459766547.822:130): proctitle=2F7573722F7362696E2F61706163686532002D6B007374617274

I'm using plink to run a command on a Unix remote machine.
The command is:
ls -1trd testegrep.txt |tail -1 |xargs tail -f| grep 's';
The way I'm sending this command is by using a file with a set of commands like:
plink.exe -ssh -t -l user -pw pwd tst.url.pt -m commands.out
When I run the command this way the plink does not receive any input. It seems that is waiting for input.
But if I run:
plink.exe -ssh -t -l user -pw pwd tst.url.pt "ls -1trd testegrep.txt |tail -1 |xargs tail -f| grep 's';"
I get the expected result.
I'm not using the plink with a file with the command because I choose so. I'm using a test automation software that allows me to run tests on remote hosts and this is the way the tool works.
Any thoughts on what is going wrong?
I tested the command you provided and it worked without problems.
Maybe the problem is related to:
The server's host key is not cached in the registry.
The path to the file is not correct.
The file is empty.
include server hostkey
most importantly, you need to include the unix profile using the -m paramater
You can include all your commands in the same file where the profile is kept also.
$Output = ((plink.exe -hostkey hostkey -l UNAME -i SSHKEY -P 22 -ssh server -batch -m PROFILE) | ? {$_ -ne ""})
