General :: Automate Ftp Session Without Bare Password Being Seen?

Mar 11, 2010

I need to ftp some files nightly from my linux box to an arbituary ftp server not controlled by me.

The ftp server admin has granted me an account for the purpose, but do not wish me to store the plain username or password in any script files for security reasons. How can I do that?

the wrong way would be:

$ cat my_script
open server_address
user plane_ftp_username plane_ftp_password
put a.txt

Ubuntu Servers :: Automate Grub - Send Commands To It Via Ssh?

Sep 9, 2010

I have a server that is triple boot and the server is headless and accessed using ssh. So is there a way to tell grub before hand what os to choose or send commands to grub (of course I get rid of the timeout) to pick a different os other than the default one. Any ideas? I already know this is bad practice to have multiple os's on the same machine to be used as a server, but what about selecting a different kernel at start up.

Programming :: Automate The Password Prompt Required For Sudo Commands?

May 31, 2011

I have written a script to run commands on remote servers, it is working fine. But when I am running "sudo commands" on the remote servers, it asks for me password after prompting for ssh password. I am unable to automate this password prompt (which is just after ssh password prompt). This is the function I am using to provide passwords


pass ()
cd $DIR/"$dt1"_"$dt"
/usr/bin/perl << 'EOF'
use strict;


I want the same function to be used , when it expects for sudo passwords for any of the below lines:


[sudo] password for vikas: orPassword: This is my "cmd" file passed in pass () function.


ssh -t -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no "bash rcmds"

This is my script output


[vikas@box1 ~]$ ./
++ rm -rf /home/vikas/May_31
++ mkdir -p /home/vikas/May_31
++ set +x


how to automate the password prompt required for sudo commands.

Software :: Running X-Server From Remote Shell Session?

Apr 7, 2010

How do I obtain information about the running x-server from a remote shell session? I want to know things like resolution, color depth, etc. My xorg.conf is basically empty. The only thing I can think of doing is to read the Xorg.0.log file which seems inefficient.

I thought that 'xrandr' displayed some text output but that behavior has changed (?). It seems to require an X display. Is there another way? Something I could incorporate into a shell script? (This is Fedora but that shouldn't really matter)

Ubuntu :: Telnet Session Hanging On 9.04?

Apr 25, 2010

I am running Ubuntu 9.04 on a wireless networked host machine. The wireless NIC is usb based. Its running inetd for network based servers (telnet, ftp etc).For some reason telnet, ssh or any application specific connection, hangs for a few seconds and then comes back. This happens after every few minutes. I do not loose any sessions or any data flowing across but it is sort of very annoying.It is a dual boot machine and I have also got Windows XP 64-bit. When am running on windows this does not happen, hence am not sure if it is something to do with the wirless nic or something else

Ubuntu :: Can't Spawn Telnet Session In Expect Script

Apr 22, 2010

I am moving my migration forward and am trying to get my expect scripts tested and found one that no longer works. Quite simply, it spawns a telnet session to a router.

set env(TERM) vt100
set timeout 3
set send_human {.1 .3 1 .05 2}
set timeout -1
spawn telnet

and that's it. The result of the script is that the command to spawn simply shows up on the screen like it is a puts command. On my older openSUSE system, it worked fine. I am running Ubuntu v9.10 desktop, and expect and its libs are patched to the latest rev, expect is 5.43.0.

Software :: Process Running Even After Telnet Session Has Been Deliberately Ended?

Mar 28, 2011

I have ubuntu 10.04 & I telnet to windows vista. Even if I create a hidden process [URL].. from batch file . It seems the process gets killed when I end connection at port 23 to host. Maybe , the hidden process created is still child of current telnet session so tree is killed as session ends. Is there a way to keep process running even after telnet session has ended ?

CentOS 5 Server :: Login As Postgres User And Enter Commands?

Sep 10, 2010

I've had a server setup working perfectly for the last 2 years. Today we installed a newer version of postgresql and recompiled apache/php.

Postgresql will not start now.

"service postgresql start" = /var/lib/pgsql/data is missing. Use "service postgresql initdb" to initialize the cluster first. To initdb we need to be as user postgres.

"su - postgres" = "no file or directory"

In /etc/passwd = postgres:x:26:26:PostgreSQL Server:/var/lib/pgsql:/bin/bash

how i can login as postgres user and enter these commands?

Programming :: TCL Expect Script That Spawns A Telnet Session To A Nortel - Response In Expect_out Is Not Consistent

Dec 2, 2010

I have a TCL expect script that spawns a telnet session to a Nortel DMS100 to execute some commands. The strange thing is that the response in expect_out is not consistent. It sometimes contains a extra enter or newline. This results in differences in the expect out buffer. Here is a part of the script:

send "time
sleep 1
expect -re ">"


This command displays the time. The correct output should be (with log_user=1):

Time is 11:44:04

But sometimes the output is:

>timeTime is 11:45:04

As you can see here the is missing on the command that expect sends , or at least in the echo that is comming back. I use a split command to filter out the response in the expect_out buffer, but this fails when the is missing. Here is a example with the debug enabled:


I suspect it has something to do with a slow response of the switch. I tried to send the time command slow and with the send_human but the result is the same. A timeout between the send and expect also doesn't help.

Ubuntu :: Telnet: Unable To Connect To Remote Host: Connection Refused

Jul 16, 2010

when i try a telnet to a host like that: telnet 1234 i got this: telnet: Unable to connect to remote host: Connection refused.

1/ does this mean that the problem is not due to a firewall, but that the host doesn't listen on the port 1234? other way does this mean that my firewall is authorizing traffic on the port 1234?

and when i try a telnet on another port like that: telnet 1235 i get: Trying ...

in this case this

2/ does this mean that the firewall is blocking the traffic between my host and the on the port 1235?
