Is it possible to do the following by expect script? I have Linux server that connected to **linux_machine1** and **linux_machine1** connected to **linux_machine2** My Linux server have access only to **linux_machine1** ( linux server can telnet to **linux_machine1** but can’t telnet to **linux_machine2** ) But from **linux_machine1** I have access VIA telnet to **linux_machine2** So my question is: I need to develop expect script that perform telnet from the Linux server to **linux_machine1** then expect will perform telnet to **linux_machine2** from **linux_machine1** and will copy the **/etc/hosts** file from **linux_machine2** to my Linux server Is this scenario can be implemented by expect script? Short example that descript the process: ( run expect from Linux server ) --> linux_machine1 --> linux_machine2 Linux server <-- /etc/hosts from linux_machine2 <-- * remark - expect script need to be activate from the linux server

Issue with pexpect , python module.

Our Linux setup doesn't have keygen configured for passwordless authentication. Hence I am supposed to use only EXPECT for passwordless authentication in a shell script. /usr/bin/expect> ${LOG_FILE} set timeout 60 spawn sftp ${EWS_USER}@${EWS_HOST}:${TGT_DIR} expect "*?assword:" send "$password\r" expect "sftp>" send "put $local_dir/$line\r" expect "sftp>" send "bye\r" expect EOF EOF filename=$(basename "$line") # echo "File Name: $filename" #Calculate the MD5Sum locally. local_md5sum=$(md5sum "$line") #echo "Local MD5Sum: ${local_md5sum}" #Calculate the MD5sum in remote machine remote_md5sum=$(ssh ${EWS_USER}@${EWS_HOST} "cd '$TGT_DIR' ; find -name '$filename' -exec md5sum {} \;" > ${LOG_NAME} put ${LOCAL_DIR}/${line} ${TGT_DIR}/${line} EOF But any idea how to use EXPECT here in the scenario below to make the connection passwordless? remote_md5sum=$(ssh ${EWS_USER}@${EWS_HOST} "cd '$TGT_DIR' ; find -name '$filename' -exec md5sum {} \;" < /dev/null)

I have a problem with my script. It seems my password is wrong. #!/usr/bin/expect set ip [lindex $argv 0] spawn telnet $ip set timeout 10 expect "Login:" send "administrator\r" expect "Password:" send "123456" send "\r" It says, login incorrect. But it works, when i use cmd on Windows to telnet to my phone, it works with "administrator" and 123456 as password. I don't know why in my script, I could not log on successfully. I have to use this script to downgrade/upgrade my phones.

The below is the sample of a script which we execute daily for getting info from the server. For the last couple of days, some server data is missing from the output which is captured on the local file VS-HV-Report_2017.txt. Is it possible to get error status when the script is executed, but its unable to connect the server? So that we have a black line or and error status instead of output? #!/usr/bin/expect set timeout 5 #find /path/to/files -type f -mtime +10 -delete set date [exec date "+%d-%B-%Y"] spawn sh -c "yes | cp -ifr .ssh/VS-HV-config .ssh/config" spawn sh -c "> VS-HV-Report_2017.txt" #cat ./info.py spawn sh -c "ssh L1n \"./info.py | sed 's/total.*//g'\" >> VS-HV-Report_2017.txt" expect "Enter passphrase for key '/root/.ssh/id_rsa':" send "passwd\r" spawn sh -c "ssh L2n \"./info.py | sed 's/total.*//g'\" >> VS-HV-Report_2017.txt" expect "Enter passphrase for key '/root/.ssh/id_rsa':" send "passwd\r" spawn sh -c "ssh L3n \"./info.py | sed 's/total.*//g'\" >> VS-HV-Report_2017.txt" expect "Enter passphrase for key '/root/.ssh/id_rsa':" send "passwd\r" set timeout 5 #spawn sh -c "./format-VS-HV.sh > format-allinement-output.csv" #spawn sh -c \"./format-VS-HV.sh\" > format-allinement-output.csv exec ./format-VS-HV.sh > /root/format-allinement-output/format-allinement-output-$date.csv

I use an interactive wallet spectre-cli of Spectre , a coin similar to Kaspa in its design. When I manually want to get the balance of my wallet I need to run spectre-cli and then connect, open from within spectre-cli. All this looks like this:

spectre-cli
Spectre Cli Wallet v0.3.16 (type 'help' for list of commands)
$ connect
Connected to Spectre node version 0.3.16 at ws://127.0.0.1:19110
$ open
Enter wallet password: 

Your wallet hint is: This is a hint.

$ $ 
• ****************
    • [********]: 4.47042578 SPR   1 UTXOs
      spectre:******************************************************

[********] • 4.47042578 SPR $

I wrote an expect script meant to do those steps for me (so that the only thing I would need to type is my password):

#!/usr/bin/expect -f

# Set a timeout (in seconds) for how long to wait for each prompt
set timeout 5

spawn spectre-cli

expect "$ "   
send "connect\r"

expect "$ "  
send "open\r"


interact

I get inconsistent output from the script. About 70% of the time I get:

./get_balance_works.exp 
spawn spectre-cli
Spectre Cli Wallet v0.3.16 (type 'help' for list of commands)
$ connect
connectopen
command not found: connectopen
$

whereas the rest of the time the script works as expected:

./get_balance_works.exp 
spawn spectre-cli
Spectre Cli Wallet v0.3.16 (type 'help' for list of commands)
$ connect
$ open
Connected to Spectre node version 0.3.16 at ws://127.0.0.1:19110

Is there a way to make the script work as expected in a consistent manner? P.S. I am on a Ubuntu LTS.

I have an expect script that will SSH into a list of routers. The expect script works on a list of routers in a file and is called from a bash script with xargs. Bash : script get-rtr.sh #!/bin/bash /usr/bin/xargs -P 10 -L 1 -r ./get-rtr-expect.sh router_list_temp list=cat router_list for i in echo $list do echo $i $foo $bar >> router_list_temp done /usr/bin/xargs -P 10 -L 1 -r ./get-rtr-expect.sh router_list_temp I am looping thru the router list, and writing to a new file with the args added. Then feed the new list to the expect script, each line of the line is arg0 arg1 and arg 2. Then wipe it clean at the end. I don't like this at all. I don't want to create a temp file, but it seems to be working. All better ideas are welcome. If router_list_temp could be an array of routers with 2 args, rather than a file, that would be better .... it would all live in RAM. but I don't know how to create and array or pass it to an expect script.

I have the following expect script which works for the most part. I have it connecting to a Cisco switch (eventually a couple hundred) and configuring syslog servers. It checks to make sure that buffering wasn't already configured and if it isn't, set it. If "logging buffered" is set, the script works fine. However, if "no logging buffered" is present, the script dies early before saving the config.

I need to **netcat** a U-Boot and perform NAND script and I use below script

spawn netcat -lup 6666
expect "Hit any key to stop autoboot" 
#autoboot counts down from 3 to 0 and somehow one or two send won't stop autoboot
for {set count 0} {$count "
send "nand info"

Just need to repeatably send "\n\r" before "U-Boot >" shows up. Is there a better way to do this?

I have a bash script that has expect to login to a remote host and run list of commands. It works as expected. It has a flaw, if the user enters the wrong password, the expect script keeps trying the password for multiple times. Some host on network are now updated to block the newer ssh connection if there was multiple ssh failure in the recent for some minutes. I am trying to modify the script so the expect breaks/exits the code if the password is wrong on the first attempt.

echo "Enter the admin password:  "
read password

I have this expect script, that will log into a host, run a command, return it's contents and exit. What sort of cleanup/proper exiting needs to happen when I've finished running my command? This command will always return something, the larger problem or issue I think I should be handling is if either SSH hangs, or if logging in as the admin user hangs. I thought I might have been handling that via timeout, but I am unsure: #!/usr/bin/expect -f set timeout 10 match_max 100000 set hostname [lindex $argv 0] spawn /usr/bin/ssh -o "StrictHostKeyChecking no" admin@$hostname expect "*password:" send -- "redactedSSHpassword\r" expect "Username:" send -- "admin\r" expect "*password:" send -- "redacted\r" expect -- "*#*" send -- "show stat summary\r" expect -- "*#*" I also don't understand the proper way of exiting this script and making sure I'm not leaving a stale session around.

I'm trying to send special characters (password) which contains #?!k;|C . The password is dynamic and cannot be hardcoded in the script, so I'm passing it as variable as shown below $ expect ./passwordlessSSH.exp $hostname "$password" the code of this script is as below #!/usr/bin/expect -f set host [lindex $argv 0] set pass [lindex $argv 1] spawn ssh-copy-id -i /home/hdpsvcs/.ssh/id_rsa.pub hdpsvcs@$host expect { "yes" { send "yes\r" } "assword" { send "$pass \r" } exit 0 But still it is not running the script properly. I don't see any error but the variable is not passed correctly. The output is as shown below: $ expect ./passwordlessSSH.exp $hostname "$password" spawn ssh-copy-id -i /home/hdpsvcs/.ssh/id_rsa.pub test@otesthost /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/test/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys \S Kernel \r on an \m test@test's password: $
