General :: Socat And Rich Terminals - No Job Control In This Shell
Mar 24, 2010
socat - exec:'bash -li',pty,stderr,ctty -> bash: no job control in this shell
What options should I use to get fully fledged shell as I get with ssh/sshd? I want to be able to connect the shell to everything socat can handle (SOCKS 5, UDP, OpenSSL), but also to have a nice shell which correctly interprets all keys, various Ctrl+C/Ctrl+Z, tab completion, up/down keys (with remote history).
- Found "setsid" socat option. It fixes "no job control". Now trying to fix Ctrl+D.
- socat file:`tty`,raw,echo=0 exec:'bash -li', pty, stderr, setsid, sigint, sane. Not it handles Ctrl+D/Ctrl+Z/Ctrl+C well, I can start Vim inside it, remote history is OK.

How can rich text or HTML source code be obtained from the X clipboard? For example, if you copy some text from a web browser and paste it into kompozer, it pastes as HTML, with links etc. preserved. However, xclip -o for the same selection just outputs plain text. I'd like to pull the HTML out and into a text editor.

Could you suggest feature-rich disk-based personal backup program for Linux (and I've seen a few)?
I want to do nightly backups of the whole system and be able to rollback to any of last 7 days. And, it must be incremental backups. What tool should I use? The tutorials I've read about rsync tell only how to store latest incremental backup and I need last 7.

I have a program that I run from the terminal that requires manual input (it's matlab in mex debugging mode, matlab -Dgdb, which starts the GNU C debugger with its own custom settings).
Every time I run this program I always type in the same few commands in the program's interactive shell before I actually start working (for example: run -nojvm; stop at mexFunction; continue). I want to avoid typing these commands and I thought I could do this with shell scripting, saving the commands in the mycommands file, then running: myprogram < mycommands
The problem is that this runs all the commands and then exits the program. I want it to run the commands and return control to me so I can run my commands. Is there a way to tell the shell to use a file or a string as the input to a program then immediately return control to the user without the exiting the program?

I've been looking for a alternative terminal to work in while using F15. I've done some Googleing and came across Konsole as being the most feature rich terminal. I'd like a terminal that provides a lot of features so I could possibly increase my efficiency. If something is KDE like Konsole does that mean I have to install the whole KDE environment? If so is there any Fedora terminal alternatives?

Do you know how to write a shell script that executes say 4 instances of the same program in different directories at the same time, and once ONE instance completes it executes a new instance of that program in a new directoryd so on, until 100 instances have been executed, each in their own directory

Here is my problems :I have two networks :1. LAN (10.1.x.x subnet 255.255.0.0), and2. my internet public (IP 202.xx.xxx.xxxx subnet 255.255.255.240)I have an application in my LAN PC (10.1.2.240) which broadcast udp packet to its client. The client in my LAN can receive the udp packet, no problem.My question is how netcat/socat can RELAY the udp broadcast packet to one of my IP public address so the message can be received by other client from internet ?

I'm setting up an Ubuntu server and I keep getting strange problems with my editor.I'm not sure if this is because my keyboard configuration is wrong or I screwed up the installation but regardless it's quite frustrating.
When using the movement keys (arrows and numpad) I get "[" brackets and "C"s, if I hold down or push down on the key hard a list of errors and text comes up, usually involving something that says something like:"Mount disabled" or "____ disabled press CONTROL-X to restart the shell"Similair problems are also found in vi (when in insert mode).I have been plagued with text editor problems and have need several reboots just to get out of a file, often because it just flat out stopped responding to keyboard commands.

I'm trying to use a C++ program to communicate through a serial port on Ubuntu 10.04. I've installed LibSerial and for now I'm using virtual serial ports using socat. I'm getting an error on compiling (found below). But step by step, first I start the virtual serial ports:
Code:

I am trying to redirect connection to port 8980 to execute a telnet command to a local machine
by issuing the following command :
In Server 1 :
socat TCP-LISTEN:8980,fork EXEC:/myscript,reuseaddr
My script contains
#!/bin/bash
telnet 192.168.20.12 //local Server 2
I am sending Binary data from the client to Server 2 via Server 1. So it happens that I have some characters in Hex translated to special characters in ASCII like open brackets or Commas etc.. and that closed the socket between the two machines.

The usual vim yank and paste works only in the same window (but does work across files and close/save commands). Is it possible to make it work across terminals (yank from window in one terminal and paste in another) and if so, how?

I am making a bash script. I have captured user input like so. code...
But it does not work. Airodump-ng "takes over" and the script does not continue.
How do I make it so that I can make a new Terminal, or allow more commands to take place on the current one, allow the output from airodump-ng to be shown, and keep the caught user input?
I'm using Ubuntu 9.10, GNOME and would like it so that anyone with a GUI Terminal, Konsole or whatever can execute the script successfully.
I'm confused...I looked up on Google and couldn't find anything! Just "Beginners guide to Bash Scripting" and "How to BASH script" but nothing relevant that answer my question!

After an update today, my kernel got upgraded to kernel-2.6.34.8-6-default. With this update, my old initrd-2.6.34.7-0.7-default got removed and corresponding grub menu options also got removed. Now after reboot,I am dropped to a shell with the last message being "no job control in this shell". I cannot startx or change to init 5. In fact, the 'boot' partition is not mounted.Even the root partition ( LVM volume ) is not mounted. I guess there was some problem in the initrd creation. I do not know the reason.An earlier post with this title seems to think problem in fstab.But my fstab was not touched by the update. How to get back to normal desktop?

I feel little silly asking this, I accidently removed from my gnome panel my internet connection, volume control and battery indicator on F11. how can I add this back. It does not show up in the add to panel menu and the applications do not give you back the default feel.

I don't know how this happened, but my keyboard copy and paste functions have stopped working. Oddly enough, I discovered that I can only copy and paste by using the third mouse button. Pressing down on the scroll wheel after highlighting text copies the text, pressing it again pastes it Ican still use the Edit-copy and Edit-paste menu functions.
I'm sure it has something to do with all the tinkering I have been doing with my desktop. I have been experimenting with CompizConfig and Cairo dock, changing my themes and things of this nature.

I cannot get any fan information from 'lm-sensors' or 'sensors', I tried to run 'pwmconfig' and got this:
Code:
Code:
But I have no tools to control the fan speed from 'acpi'. in particular '/proc/acpi/fan' is an empty directory.
There are no fan info/controls in BIOS either.
I believe the fans do not work as fast as they should and I am trying to find a way to fix this before the cpu cores are melted down from overheating.
