This script required an ip and the script or file that we have to run on the remote server i gave a file in which i have wrote commands like
touch /root/test
ls /root/test
this make the file but do not show and it is displaying an error
tcgetattr: Inappropriate ioctl for device
connection closed
How can I resolve this is there any suggestion ??
#!/bin/bash
# The private key used to identify this machine
IDENTITY_KEY=/home/admnew.pem
syntax()
{
echo "Syntax: Ec2.sh server_ip scriptFile]"
echo "For example: ./Ec2.sh server_ip scriptFile"
exit 1
}
if [ $# -ne 2 ]
then
echo not enough arguments
syntax
fi
echo "Running script $2 on $1"
ssh -t -t -i $IDENTITY_KEY ec2-user#$1 sudo -i 'bash -s' < $2
exit
exit
echo "Done"
Try:
ssh -t -t -i $IDENTITY_KEY ec2-user#$1 sudo -i 'bash -s' <<EOF
(
$(cat "$2")
)
EOF
e.g. wrap the script into (), e.g the:
touch /root/test
ls /root/test
should be
(
touch /root/test
ls /root/test
)

I have a csv file called addresses.csv which looks like this,
node-1,xx.xxx.xx.xx,us-central-a
....
node-9,xxx.xx.xxx.xx,us-east1-a
I have a script below called 0run.sh,
#!/bin/bash
username='user'
persist="bash /home/${username}/Documents/scripts/disk/persistentDisk.sh"
first="bash /home/${username}/Documents/scripts/disk/firstAttach.sh"
while IFS=, read -r int ip <&3; do
if [ "$int" == "node-1" ]; then
--->ssh -i ~/.ssh/key -o StrictHostKeyChecking=no -l ${username} ${ip} "${persist}; ${first}"<---
else
ssh -i ~/.ssh/key -o StrictHostKeyChecking=no -l ${username} ${ip} "${first}"
fi
done 3<addresses.csv
The error occurs in the part of the code where I drew the arrows.
When it runs on node-1, instead of running ..persistentDisk.sh followed by ..firstAttach.sh, it only runs ..persistentDisk.sh and gives me the following error before it runs ..persistentDisk.
bash: /home/user/Documents/scripts/disk/firstAttach.sh: No such file or directory
The rest of the script runs completely fine. The only error occurs at this one part where it misses the 2nd script.
When I run the command like this it runs fine.
ssh -i ~/.ssh/key -o StrictHostKeyChecking=no -l ${username} ${ext} "${first}"
When I run it like this, it runs fine as well.
ssh -i ~/.ssh/key -o StrictHostKeyChecking=no -l user xxx.xx.xxx.xx "bash /home/${username}/Documents/scripts/disk/persistentDisk.sh; bash /home/${username}/Documents/scripts/disk/firstAttach.sh"
When I run the command like with a \ before the ; to escape it like this,
ssh -i ~/.ssh/key -o StrictHostKeyChecking=no -l ${username} ${ext} "${persist}\; ${first}"
I get the following error, and neither scripts run within the node-1 part of the code, but the rest of the code's else loops run fine.
bash: /home/user/Documents/scripts/disk/persistentDisk.sh;: No such file or directory
Why can't I stack the 2 commands within the if statement in the ssh using variables?
If I clearly understand: your real problem consist to leave STDIN free for interaction in target host!
About read and redirection
Try using:
#!/bin/bash
username='user'
persist="bash /home/${username}/Documents/scripts/disk/persistentDisk.sh"
first="bash /home/${username}/Documents/scripts/disk/firstAttach.sh"
while IFS=, read -r -u $list int ip foo; do
if [ "$int" == "node-1" ]; then
echo CMD... $ip, $persist
else
[ "$ip" ] && echo CMD... $ip, $first
fi
done {list}<addresses.csv
Tested, this èroduce:
CMD... xx.xxx.xx.xx, bash /home/user/Documents/scripts/disk/persistentDisk.sh
CMD... xxx.xx.xxx.xx, bash /home/user/Documents/scripts/disk/firstAttach.sh
-u flag to read, tell to use file descriptor ${list} instead of STDIN
foo is some useless variable used to prevent rest of line to be stored in $ip (xx.xxx.xx.xx,us-central-a in this case)
{list}</path/to/filename create a new variable by finding any free file descriptor.
About ssh (and redirection)
You could use:
#!/bin/bash
username='user'
persist="/home/${username}/Documents/scripts/disk/persistentDisk.sh"
first="/home/${username}/Documents/scripts/disk/firstAttach.sh"
while IFS=, read -r -u $list int ip foo; do
[ "$int" = "node-1" ] && cmd=persist || cmd=first
[ "$ip" ] && ssh -i ~/.ssh/key -t -o StrictHostKeyChecking=no \
-l ${username} ${ext} /bin/bash "${!cmd}"
done {list}<addresses.csv
By using this syntax, you will keep STDIN free for script running on target host.
So for example, when a user netcats to port 7896, a script which asks for a user input will run.
Try like this. Create listener script
$ cat listener
#!/bin/bash
port=7896
input=$(nc -l -p $port) || exit $?
./test ${input:-empty}
Create test script
$ cat test
#!/bin/bash
echo $1
./listener
Run listener
./listener
And in another terminal run
port=7896
nc -q0 localhost $port 2> /dev/null <<< "hello"
Here's a server that executes foo.sh when someone connects.
server.sh
#!/bin/bash
while [[ 1 ]]; do
ncat -l -p 7896 -e foo.sh
done
foo.sh
#!/bin/bash
echo -n 'prompt> '
while IFS= read -r cmd
do
echo "got >$cmd<"
echo -n 'prompt> '
done
A sample session:
$ ncat localhost 7896
prompt> Hello world
got >Hello world<
prompt> <CTRL-D>

I am trying to create shell scripts which will setup Zookeeper Server in one VM, and its corresponding Zookeeper Clients in different VM's so i written a shell script as below
#!/bin/bash
ZOOKEEPER_SERVER_IP="1.2.3.4"
while read ipaddress zookeepertype number
do
echo -e "Setting up the Zookeepers \n"
echo $ipaddress
if [ "${zookeepertype}" = 'zookeeperserver' ]; then
echo "Setup Zookeeper Server"
#ZOOKEEPER_SERVER_IP = $ipaddress
#echo $ZOOKEEPER_SERVER_IP
#echo $ipaddress
sudo scp -i /home/ubuntu/.ssh/fd -r /home/ubuntu/ZooKeeper_Server_Script.sh ubuntu#$ipaddress:/home/ubuntu/
ssh -i /home/ubuntu/.ssh/fd ubuntu#$ipaddress /home/ubuntu/ZooKeeper_Server_Script.sh
echo "This script is about to run ZooKeeper_Server_Script."
echo "The server script has completed.";
#sleep 30
exit 1
fi
echo -e $ZOOKEEPER_SERVER_IP
if [ $zookeepertype = "zookeeperclient" ] ; then
echo "Setup Zookeeper Client"
echo $ipaddress
sudo scp -i /home/ubuntu/.ssh/fd -r /home/ubuntu/ZooKeeper_Client_Script.sh ubuntu#$ipaddress:/home/ubuntu/
ssh -i /home/ubuntu/.ssh/fd ubuntu#$ipaddress
#mkdir /home/ubuntu/keyfiles
#exit
#sudo scp -i /home/ubuntu/.ssh/fd -r /home/ubuntu/abc/network/test/keyfiles/* ubuntu#$ipaddress:/home/ubuntu/keyfiles
#sudo scp -i /home/ubuntu/.ssh/fd -r /home/ubuntu/abc/test/simple/abc.json ubuntu#$ipaddress:/home/ubuntu/
#ssh -i /home/ubuntu/.ssh/fd ubuntu#$ipaddress
#chmod 777 ZooKeeper_Client_Script.sh
#echo "This script is about to run ZooKeeper_Client_Script."
#sh ./ZooKeeper_Client_Script.sh $ZOOKEEPER_SERVER_IP
echo "The client script has completed."
#exit
fi
#Separating Runhosts File
done < setupZkinput.txt
the input file is
1.2.3.4 zookeeperserver 1
5.6.7.8 zookeeperclient 2
9.10.11.12 zookeeperclient 3
The issue that i am facing is
1) Only the server setup is being done , i.e the script is exiting after the first line
2)Not able to assign the server ip dynamically , in the line ZOOKEEPER_SERVER_IP = $ipaddress
Thanks
What is the default permission you are setting up after copying a file to the server?
remember it required execute permission in order to execute script.
I'm sending a command through ssh:
ssh server.org 'bash -s' << EOF
ls -al
whoami
uptime
EOF
How to log it in the system (remote server)? I'd like to log those commands in some file (.bash_history or /tmp/log).
I've tried to add the line below to sshd_config:
ForceCommand if [[ -z $SSH_ORIGINAL_COMMAND ]]; then bash; else echo "$SSH_ORIGINAL_COMMAND" >> .bash_history; bash -c "$SSH_ORIGINAL_COMMAND"; fi
But it logs "bash -s" only.
I'll appreciate any help.
When bash shell exits, bash reads and executes commands from the ~/.bash_logout file. Probably you can run the history command at the end in the .bash_logout(of the server) and save it to some location.
If it suffices to work with the given command, we can put the necessary additions to enable and log command history at the beginning and end, e. g.
ssh server.org bash <<EOF
set -o history
ls -al
whoami
uptime
history|sed 's/ *[0-9]* *//' >>~/.bash_history
EOF
Or we could put them into the awfully long ForceCommand line:
… if [[ "$SSH_ORIGINAL_COMMAND" == bash* ]]; then echo "set -o history"; cat; echo "history|sed 's/ *[0-9]* *//' >>~/.bash_history"; else cat; fi | bash -c "$SSH_ORIGINAL_COMMAND"; fi
I have a small list of servers, and I am trying to add a user on each of these servers. I can ssh individually to each server and run the command.
sudo /usr/sbin/useradd -c "Arun" -d /home/amurug -e 2014-12-12 -g users -u 1470 amurug
I wrote a script to loop through the list and run this command but I get some errors.
#!/bin/bash
read -p "Enter server list: " file
if [[ $file == *linux* ]]; then
for i in `cat $file`
do
echo "creating amurug on" $i
ssh $i sudo /usr/sbin/useradd -c "Arun" -d /home/amurug -e 2014-12-12 -g users -u 1470 amurug
echo "==============================================="
sleep 5
done
fi
When I run the script it does not execute the command.

What is wrong with my ssh crommand in my script?
Try this script:
#!/bin/bash
read -p "Enter server list: " file
if [[ "$file" == *linux* ]]; then
while read -r server
do
echo "creating amurug on" "$server"
ssh -t -t "$server" "sudo /usr/sbin/useradd -c Arun -d /home/amurug \
-e 2014-12-12 -g users -u 1470 amurug"
echo "==============================================="
sleep 5
done < "$file"
fi
As per man bash:
-t
Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote which can be very useful, e.g. when implementing menu services. Multiple -t options force tty allocation, even if ssh has no local tty.
