hi all how do i use php to pass commands onto a server? like i want to be able to:
1. delete the content of a file (or just delete the file and make a new one if it's easier)
2. read the content from a file
3. write new data to a file via an input box
4. run a command on the server
So, I have a netbook with a 320GB harddrive and I'm testing all kinds of fun distros out. Right now I have 11.04, 11.10 daily, Jolicloud, Chromium OS, and MeeGo. Meego uses it's own weirdass boot loader, which sets things up a certain way. My computer has a touchscreen, and I had to modify some things to get it all working properly. Anyway, I reinstalled grub on my main partition (11.04), but now the command I need doesn't go through to meego.
The command is "usbhid.quirks=0x0eef:0x725e:0x40" For my other systems, I have it in /etc/default/grub in the "GRUB_CMDLINE_LINUX_DEFAULT=" line.
Obviously there is nothing like this in Meego, and a thread on their forum said I would have to configure it in whichever bootloader I'm using.
I am attempting to script some tasks I have to do, but I have no control over one of the scripts I have to use... and they output all kinds of useless things on the screen. My goal is simple: Capture all output from their scripts, and create a progress line that only shows the most recent output from their stuff. So, here was my first solution; a file I called "spin":
Code:
#!/bin/bash
spinX(){
PROC=$1
STRT='date "+%s"'
while [ -d /proc/$PROC ];do
last3=" 'getLine $2' "
To use it, you pass it a process ID and a file that contains the output from that process. As the process continues, a kurby dances on the screen (To let you know that the process has not hanged), and the tail of the output is shown (To let you know what it is doing). When the process ends, the kurby stops dancing and the time it took is displayed.
And here is the file I call "noise":
Code:
#!/bin/bash
while [ i -lt 100 ];do
i=1
echo "Look at me count!$"
sleep 1
let "i=$i+1"
done
This does nothing but create random output, for testing. It counts from 1 to 99 on the screen. To run my test, I do the following:
Code:
(noise) &>tmp.txt & spin $! tmp.txt
It works relatively well, but it is messy. I don't like creating a temp file, and I don't like the messy syntax for calling my program. I decided that I would rather move everything into the spin program, to make using it less messy:
Code:
#Spin Psuedo code
#$1 = command I am about to run
(exec $1) &>tmp.txt & spinX $! tmp.txt
By executing the process inside of the spin code, I can get rid of the tmp file later on without changing a lot of scripts (Or move it, or whatever). I can also call it by passing the command to the script, which I find more elegant.
So here is what I would like to know:
1) If possible, I would love to get rid of the tmp file all together, and store the most recent line of output from script 1 into a variable that script 2 can print out instead... is it possible?
2) How can I run a random command that is passed as an argument? Basic ones work fine, but anything with a pipe fails me.
Example of a script:
Code:
#!/bin/bash
#myEcho.sh
echo;echo "Recieved command: ";echo $1;echo;
echo "Attempting to run command: ";echo
exec $1
Example code for passing commands to script:
> myEcho.sh "ls -al" #works
> myEcho.sh 'ls -al' #works
> myEcho.sh "ls -al|grep *.sh" #fail
# Output:
#ls: invalid option -- |
#Try 'ls --help' for more information.
> myEcho.sh "ls -al|grep "*.sh"" #fail
# Output:
#ls: invalid option -- |
#Try ls --help' for more information.
> myEcho.sh 'ls -al|grep *.sh' #fail
# Output:
#ls: invalid option -- |
#Try 'ls --help' for more information.
I'm trying to write a python script that will use the current user's name when interacting. Ex: when started, it should say "hello daweefolk" when I am logged in.
I've tried
Code:
username=os.system("echo $USER")
but the variable remains empty.
What is the correct code?

My Server is Ubuntu 9.10x64 running in a 64bit vmware on a Dell Optiplex 760. I have the Ubuntu amd64 mirror downloaded locally in /var/spool/apt-mirror/mirror/ubuntu.mirror.iweb.ca/
I am not working with any other **buntu flavours.
tftp and dhcp are all working from what i can tell. My client can boot from the PXE, get an IP address, and takes me into the Kickstart loader.
For some reason, it is not reading my ks.cfg. I get the blue screen that says the following: "The installer failed to download a file from the mirror. This may be a problem with the network or with the mirror. You can choose to retry the download, select a different mirror or cancel and choose another installation method.

I have been working in Linux for the past two years.And working in squid for the past 6 months.The following is my Setup

Using Iptables I forward 80 port through squid (3128).Other ports just get connected in the proxy machine itself since it has IP_FORWARD enabled. All my client machines browsers enabled with "Use proxy 3128". I just want to make all the port to pass through squid server.

My first post here. I've been using Ubuntu Server edition (Hardy) happily for some time now. I use sudo regularly during configuration of new services. It always works/authorises within seconds, however, it recently became very slow, to the point of being nearly unusable. It turns out that ANY authentication request stalls in this way - in in a plain shell, X or Gnome, via VNC (and even FTP seems affected). In /var/log/auth.log I noticed a regular working pattern like this:
[Code].....
Unfortunately now, these records look the same, but the timestamps are much wider apart (minutes). The problem occured after running synaptic and dpkg-reconfigure obm-conf. I was trying to remove 'OBM' [URL] completely as I'd messed up (just OBM) while trying to fix a minor-looking misconfiguration.
I've carefully analysed which files were altered (modified) during my changes (as the problem survives a reboot), but there are no likely-looking candidates in the list (I deleted some blank lock files). I also did a wireshark capture during an authentication session and noticed that it doesn't appear to be looking off the server for information (I had likewise-open installed, but the problem exists whether that is running or not). Research in the forums hinted that this might just be as simple as a bad /etc/hosts file - but /etc/hosts has not been modified. I may have a flawed DNS, but I get fast enough responses to nslookup and can access Internet etc.
I'm in the process of starting a migration from an old postfix server to nice shiney new exim server however there are a few things i'm really not clear on and i'm hoping that some one here could point me in the correct direction. Okay the postfix server at the moment does the follwoing ( i'll try and keep this simple ):
* accepts incoming mail for users on multiple domains and puts the mail in the users mailbox ( external -> internal )
*accepts mail from users on multiple domains to pass on to the outside world ( internal -> external )
Obviously the POP and Imap functions are handled by other daemons.. I'd like to replicate this sort of setup on the new exim box, however the guides i can find only help with configuring the exim system for incoming mails ( external -> internal ) for multiple domains and i cant seem to find a guide that would indicate how to do both ( internal -> external and external -> internal ) on one box. I'm guessing i may have to do some sort of auth to get exim to accept and then handle the internal -> external side of things?

I have debian lenny, when I run an application is slow to load (example: iceweacel open and it takes, I can hold him iceweacel work normally), I tried to change from gnome to another and the same thing, went down some services (samba, squid) and nothing. I open a terminal and it takes, I want to duplicate it and do it fast. From a terminal without X (tty1) with root run mc and moves quickly, also run as root "sudo mc" and takes to boot.Any action done with sudo it takes to run.
Can not be what it takes to make starting the applications, not the PC because it is new, and from one moment to another I began to pass this
The sudoers file is fine, in the log's nothing unusual, since other PC take long to enter samba.
I have a Fedora 10 machine that I want to setup to send email. However I don't want it to be a full blown SMTP setup.What I am looking to achieve is when something sends email from the local machine (e.g. from cron) to an address I want it to use an MTA on the local machine which will then connect to, and authenticate with, my e-mail providers SMTP server this will then take care of actually sending the e-mail.I don't want, or need, to setup a full blown SMTP service (i.e. only the local machine should be able to use it) so sendmail seems a bit over the top for my needs. Nor do I want to mess about with MX records (am I right in thinking this will mean I have to manage all mail for my domain?).

I'm attempting to do a low level wipe of a server in our office. I originally attempted to use DBAN but it wouldn't recognize the disks.
I've now moved on to attempting to use a Live Boot of Ubuntu 10.10 on a USB drive.
I'm using the following terminal command - sudo dd if=/dev/urandom of=/dev/sda bs=1M
When I did this the first time it simply wiped the USB drive that had Ubuntu on it.
What do I need to do in order to have it wipe all 4 disks on the server instead of the USB Drive?

If I do created their group on server B...etc and give the group sudo it would still ask for passwords right? Can I overcome this?
