OK I have a simple script that does:

echo "$password" > "$pwFile"
But I get an error message:

I wanted to find and replace a string from a perl file. I have written a script in bash which runs the following command.
perl -pi -e "s/$findstring/$replacestring/" testfile
where as $findstring = print F_WC_TMP"$line
";
and $replaceString = $line = join ' ', split ' ', $line; print F_WC_TMP"$line
";
But when I am running the above command, i think it is replacing the $findstring with the above mentioned string and hence it contains a $line, it is looking for the variable $line and not finding the exact string. I am confused about how to search for a string that contains $ in it and replace it with another $string.
I have a String that I would like to sign using a given RSA Private key. I thought this would be relatively easy but I have not been able to find out how to do it, unless I'm looking to far into a simple problem. Do i have to put the string into a file, and sign the file, or can i just sign the string/message?

I have a Tomato router and it has the capability to have its logs go to a external server. syslog is the obvious choice for this. So I enabled remote logging on my linux server's syslogd (syslogd -r) and I can see all of the logs in /var/log/syslog. What I want to do is take everything that comes from the IP of my router (10.0.0.1) and divert it to its own file like /var/log/tomato to avoid polluting my syslog with external logs.
I can't find any examples of someone doing this. My only solution is to get a script together that strips out any line in /var/log/syslog with 10.0.0.1 in it and puts the line into /var/log/tomato and have the script run as a cron job, but that seems unnecessarily messy.
Unless someone knows that there is a solution, I'm 95% sure that syslog doesn't support this after reading more in-depth of the man page. So I need to migrate to syslog-ng or make a crazy script that runs with cron.
Years ago on AIX I used to create a file of key strokes, including function keys (mainly F3 and F12) into a file, and used that file as input to an INFORMIX program, to automated tasks, something like this:
fglgo myprogram.fgo <keystrokefile.txt
Now, I'm using Aubit language on GNU/Linux, and I'd like to do the same kind of thing, but I can't recall how I worked out the chars for the function keys, I'm using a different emulation (xterm), and I can't work out what characters to put in the key stroke file. My $TERM variable contains "xterm". If I type "infocmp", I get this:
Code:
# Reconstructed via infocmp from file: /usr/share/terminfo/x/xterm
xterm|xterm terminal emulator (X Window System),
am, bce, km, mc5i, mir, msgr, npc, xenl,
colors#8, cols#80, it#8, lines#24, pairs#64,
acsc=``aaffggiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz{{||}}~~,
[Code]....
1. Is the above infocmp output the place I should get the information I need?
2. What chars do I need to put into my file to simulate me pressing F3 and F12?
3. Is there a way for me to put such chars in a file by just pressing those function keys (I tried a here document, but that doesn't work (it's as if the function keys are not even pressed)).
I have a problem with my script. The problem is the system keeps rebooting after I put the directory file in .bashrc. The intentional for putting the file in .bashrc is to run the script automatically after login as root, I don know why is this happen. It was working fine for the first time without putting the file in bashrc. I could break the loop after hitting the "ESC" key. would it be the script problems?
Here is my script
count=20
while [ $count -gt 0 ];do
sleep 1
echo Press ESC to break the operation
((count=count-1))

Here is a way to prepare a USB flash drive to save your kickstart file to it, and then read the kickstart file from the USB drive during a new Fedora installation.A USB flash drive is recognised by the Linux kernel as just another hard drive.This is how I set up my USB flash drive to use it to store my kickstart file on.You will need a working Linux system to set up the USB drive.

It will eventually be uploaded to a large number of hosting accounts, and modified from time to time...so it isn't feasible to modify that many httpd.conf files each time we need to add an IP to be blocked. In httpd.conf I can add the "Deny from" line to the following directive and blocks it just fine:
Code:
<Directory "/var/www/html">

# Possible values for the Options directive are "None", "All",

There is an include to pick up all *conf files in ../conf.d, and everything else in there is working just fine. I created a file called robots.conf; it currently has a set of mod_rewrite rules which work. So I added this to that file:
Code:
<Directory "/var/www/html">
Order allow,deny
Allow from all
Deny from 123.456.789.098
</Directory>
It is not blocking access from the IP with it in there.I've done all of the usual things; restarted Apache, cleared browser cache etc. I can also block it using that same directive in a local .htaccess.

View 8 Replies View RelatedI'm looking for a way to make a bootable floppy that has drdflash.img, my flash utility and my bios file on it for a bios recovery disk. This is on a board that has a failed bios, so everything is pretty much dead (except for the humble floppy drive). I don't have a screen to work with so this floppy needs to be able to run the utility and automatically flash the chip for me. I've heard this is possible, but am unable to find clear instructions on how to do any of this. I know the basics of it is to copy the bios file and flash utility to a floppy along with a bootdisk that will run these things (sometimes the .bat file needs to be modified in order to do this automatically). So I've downloaded drdflash but it came as a .img and I don't think it can be 'just' copied to disk. I came across the 'dd' command but have also heard its nicknamed 'data destroyer' or words to that effect.
