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 ?

View 4 Replies View RelatedI 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

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.
#!/usr/bin/expect
set env(TERM) vt100
set timeout 3
set send_human {.1 .3 1 .05 2}
set timeout -1
#
spawn telnet 10.254.3.232
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.
On my ubuntu 9.10 pc i am not running a GUI.
Every thing is run from command line.
How do i start a second telnet session from command line.
Plus can i have 4 telnet session open and move from one to the next and back again.
where to set the telnet session timeout for the IDLE time in redhat linux.

View 4 Replies View RelatedI 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 ">"
[code]...
This command displays the time. The correct output should be (with log_user=1):
>time
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:
[code]....
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.
I have a project that I'm working on now that is using Ubuntu 8.04LTS to create a reverse SSH proxy for a telnet process. We have the box logging in with RSA keys so that it can automatically connect to the SSH host on our end. We are using autossh to keep the connection up and running.
We have rolled out 3 of these and they are working very well. We ghosted the original, changed the hostname, changed the IP info, and regenerated the SSH keys. Now I need to clone 35 more. I want to try to do this as efficiently as possible and can script the changes in the hostname, IP, ect.
Can I batch create RSA keypairs on my workstation and then copy them over as a part of the batch? My current other option is to login to each of them and generate the pair. I would like to just install the drive and ship it and not even have to boot it up.
I have got three computers at my home[A,B,C] ( all connected to each other), now I connect to B from A using telnet( $telnet ip_B) , but when I try to connect to C using this telnet session( telnet > open ip_C) , I get this error, "already connected to xxx". Is it possible to connect A to B and then use that session to connect to C, so that C finds that the request is being asked by B.

Sometimes I connect to my Debian box from another computer (using SSH on Cygwin or Linux), and once ina while I want to run some console apps. And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.

For instance, I ssh from my local box to dev-formbox and did an scp transfer to another remote host. All of the sudden, I lost ssh connectivity on my local box due to network issue. Will the scp process (or any of my process that I am currently doing) kill also once I loose the ssh session?

In MacPorts, the ports I would be looking for are the requested ports. They have a system so that when you install a port, that port is marked as requested. Also if you want to keep a port that was installed as a dependency, you can set it to be requested manually. Does the Debian system have the same functionality? It seems that there are some utilities that get that done..

I was working normally and the GUI just failed, all I could still see were any open windows. I rebooted the machine from tty1 and now I can't login anymore under my normal user accounts.
I enter my credentials, it appears to login, and immediately goes back to the login screen. Note that under tty1 I can still login with my user account and do everything.
I can still login with root in the gui.

There are often times when the best way to launch an application is from the terminal, but it is a graphical application and after it is launched the terminal is useless.
Examples of places where a terminal is convenient are when a process starts lots of child processes and is also unstable; you can be sure to kill all of its children simply by using Ctrl-C at the terminal. Also it allows me to read program output and to set up the terminal environment to be optimal for the application (for example "unset LIBGL_ALWAYS_INDIRECT")
With GNU screen, I can get around the hassle of having a terminal window open by using something like the following in a terminal window:
Code:
screen
my_command
Ctrl-A d
and then I can close the terminal and the program will keep running. Then I just type "screen -r <Tab>" (the tab will get me my screen session if there is only one such session) in any terminal window, even a tty, and I can get the screen session back and use Ctrl-c or something.
So my question is, is there a way to do this automatically so that a launcher or script will start a screen session, inside that screen session start a process, and then detach from that screen session without me having to manually open and close a terminal and type the commands?

I'm running Ubuntu 10.10.
I have both a mac and ubuntu box sitting on my desk. I work on the mac and access the ubuntu box over ssh.Often I need the point-and-click interface of the ubuntu box, at which point I run gnome-session. The problem is that the top and bottom menu bars fill the full size available to them, which can cause me problems (I use two different-sized screens and the barsget hidden), and overall it looks very messy. I would therefore like to confine the gnome-session to a window, much like you get with vnc (or parallels if you're running a virtual ubuntu session).
