Ubuntu :: Ssh Server/Desktop Computer And The "write" Command
Aug 30, 2010
I have a computer set up running Ubuntu 10.04. It is being used as both a desktop computer with a mouse, keyboard, and monitor and users running GNOME sessions AND an ssh server for remote command-line access.
Now, when I am remotely accessing this machine via ssh, I see messages sent to me via "write" or "wall" without a problem, as do all other remotely logged in users. However, "writing" to a user or writing to a wall (for example about an upcoming reboot or downtime) does not affect users sitting at the actual computer in GNOME without a Terminal open. How can I get a message to these users, preferably using write and/or wall?
I have root access to this system.

Every once in a while I see a great deal (like this one) on a Dell Server. I was wondering if there was any problems running Ubuntu on one of these machines for use as a desktop computer? I don't know much about servers but the specs look similar to a desktop computer.

I am trying to write a perl script which will give an interactive session to a user to execute command on the server. I have written a small script to do this :
Code: !/usr/bin/perl -w
use strict;
use Net::SSH::Perl;
my $host = '192.168.1.1';
my $username = 'user';
my $login_passwd = 'test123';

I've been trying to find a way to watch videos from my main desktop computer on another computer I've plugged into an HDTV. I'm such a Linux newbie that I decided to give Mythbuntu a try. It was way to complicated for what I needed, and I'm sure that some more experienced people reading my first two sentences laughed to themselves at my naivety.
What I am trying to find is simple: browsing one computer's home folder from another computer, and playing the videos therein. If there's anything like Mythvideo that requires less than half of the skill requirements, I will telepathically send love to the person that informs me of it.

I am playing around with the idea of being able to use a cloud or instance based service to install Ubuntu 9.10 Server. This will enable me to have remote access via SSH command line.So far, I've installed Ubuntu 9.10 Server + Ubuntu Desktop to a virtual machine. I can access this via SSH and locally via the desktop. However, in the real environment the only access I am going to have initially is via SSH.
I would like to be able to connect using Windows Remote Desktop or VNC (whichever is easier and most importantly - most secure) to the machine.. even though the desktop is on there, I need to somehow configure the remote access all from the command line.I've had a read of various forums and have been trawling support forums for days but can't find a working solution for 9.10 Server or that fits my situation above where I will not have any physical access to the desktop or machine to configure remote desktop. It all has to be done via SSH/command line.

I am using fedora 10 in two computers. Just for my own practice I sent a file to my second computer.
1st computer IP is 192.168.1.10
2nd computer IP is 192.168.1.20
[Code]....
The file has been successfully copied to the second computer but I again want to copy that file into my local computer by still sitting in my 1st computer.

Looking for a light desktop for a P3/512MB I installed xubuntu and I felt it slow. For a test, just tried installing lubuntu and it was so fast compared to xubuntu. The word here is I would like to move to xfce. Doing another test, I installed Debian Lenny + xfce and was way much faster than xubuntu.
My question: Can I install Ubuntu Desktop command only + xfce ? Is it going to be faster than xubuntu? Is there another recommendation for a debian based distro with xfce which runs faster than xubuntu?

I'm trying to set up sshfs on a desktop/fileserver so that I can mount its HDD's I use for storage on my laptops. My issue seems to be getting permission to write to the mounted drives. I just keep getting permission denied. here is what I think are some relevant tidbits.
mount point on server,
Code:
joe@joe-desktop:~$ ls -ld ~/sda2
drwxr-xr-x 2 root root 16384 1969-12-31 19:00 /home/joe/sda2
HDD I'm trying to mount
Code:
joe@joe-desktop:~$ ls -ld /dev/sda2
brwxrwxrwx 1 joe disk 8, 2 2010-10-17 15:22 /dev/sda2
Mount point on client
Code:
joe@joe-laptop:~$ ls -ld ~/sda2
drwxrwxrwx 2 joe joe 4096 2010-10-17 19:58 /home/joe/sda2
This is the command I'm trying to use to mount
Code:
sshfs joe@192.168.1.103:/home/joe/sda2 ~/sda2
I can chmod the mount on the server to 777 but as soon as I mount the HDD to the server all write permission just goes *poof* and its back to "drwxr-xr-x".Chown seems either, it just wont stick.

The write command just isn't working for me at all. Am I right in thinking it can even do this function? I am using:
Code:
write paul@paul-laptop pts/0
It keeps telling me
write: paul is not logged in on pts/0

I've been looking for how to set this up in bash with no luck so far. I can change what file the history log is written to, and how much history is saved. But it only writes the saved part when bash exits. Instead, I'd like to have bash write that file continuously as each command is entered (and maybe also do an fsync(2) to flush it to disk). That way I can see the command I crashed the box with Anyone know the magical incantation for that?
But there appears to be nothing that I can find there, in the man page, or other searches, that suggest it even can do continuous.

When I log on a root and attempt to issue the command Freshclam to upgrade the virus definitions it attempts or create a new file with a definition name. I get a message stating that the directory isnt writable. The user and group access rights are as follows:
USER = read, write, execute
Group = read, write, execute
All= read, execute.
The only way I can get around this is by applying a 777 which would be read, write and execute for all. Now, I have a group define with several user ids in it including Root.How do I connect the group with the directory/file so I dont have to apply a 777 access right to group users could issue the Freshclam command.

My desktop computer that i dont use very often, that runs Windows XP, but im trying to install ubuntu 9.10 on it from an old CD i have but the drive wont work. It doesn't work with anything!
So heres what ive found: In my my computer area it shows that there is a "DVD/CD-RW Drive (D: )" and a "CD Drive (E: )" and when i click on the E drive it says to insert a disk into the drive and when i click on drive D it opens to a blank page. Also when i click eject on E nothing happens but when i click it on D the drive opens.
Ive already said this, but when i put a disc in it nothing happens. It doesnt matter what i put in it either, when i put something in the light saying its working blinks a few times then stops and nothing else happens.
I dont have any internet on the desktop. And ive been having this problem on & off since the computer was givin to me, but its never not worked for this long.

I am trying to figure something out as part of something else I am going to do. I was just wondering the easiest and quickest way to run a loop at the Linux command line which will make x amount of symbolic links when I need them.
I am using Debian 5.
I figure its something as easy as ~# foreach statement, then I just do a loop with the command to make a sym link.

I'm trying to write a bash script program in the Linux command terminal that will write to a fellow user and then continue reading down the program. this is what i have (kind of explains the idea too):
#!/bin/sh
clear
echo "this is before the write command"
write jcummins
this message should go to jerry
echo "the message didn't send and this string will not appear"
echo "it appears it has stopped at the write command"

Downloaded and played latest Ubuntu (10.10) to get an idea of how it works (without actually installing it). Currently i use windows 7. When I restarted my computer all my desktop icons had disappeared. I still have the programs in my documents file or wherever but my desktop is clear. Is there any way i can restore them without doing it one by one? i.e. get back to my previous state.

I have a number of queries but will start with one. I presently operate 11.04 Classic (no effects). OS is NOT set up as dual boot. As I am considering purchasing a new Desktop, I am wondering what is the best way to recover such things as folders, Firefox bookmarks etc. for four users.
I do have a external HDD which I guess could be used for a possible backup if that is the way to go! The new computer will probably have Windows 7 installed with which I assume I would probably dual boot.
