|
|
That was a funny case I've read in some government forums.
If you've ever sought FBI's help in securing your servers/routers(after you've been hacked and your lost exceeds $5000) then the first thing they'll tell you is to remove all welcome messages that sound so 'inviting'. E.g. "Welcome to...." "Greetings!" "Enjoy your stay in....", etc.
There was a case that a guy lost his legal ground in suing a cracker because he had explicitly granted right to others to enter his server(router? can't recall).
We were ordered to remove all 'inviting' message in public servers and routers when I were working at IBM.
The welcome message recommended(by FBI?) is like "Only authorized personnel is allowed to access to.....you forfeit your legal right by...." something like that. I lost the exact message already, but it sounds scary. 
Of course, I think a penguin picture is okay. |

|
|
I think I found one example I note previously that shall be used in production server:
| Code: | THIS IS A DEPARTMENT OF DEFENSE COMPUTER SYSTEM. THIS COMPUTER SYSTEM,
WHICH INCLUDES ALL RELATED EQUIPMENT, NETWORKS AND NETWORK DEVICES
(SPECIFICALLY INCLUDING ACCESS TO THE INTERNET), ARE PROVIDED ONLY FOR
OFFICIAL U.S. GOVERNMENT BUSINESS.
DOD COMPUTER SYSTEMS MAY BE MONITORED BY AUTHORIZED PERSONNEL TO ENSURE
THAT THEIR USE IS AUTHORIZED, FOR MANAGEMENT OF THE SYSTEM, TO FACILITATE
PROTECTION AGAINST UNAUTHORIZED ACCESS, AND TO VERIFY SECURITY PROCEDURES.
MONITORING INCLUDES "HACKER" ATTACKS TO TEST OR VERIFY THE SECURITY OF
THIS SYSTEM AGAINST USE BY UNAUTHORIZED PERSONS. DURING THESE ACTIVITIES,
INFORMATION STORED ON THIS SYSTEM MAY BE EXAMINED, COPIED AND USED FOR
AUTHORIZED PURPOSES, AND DATA OR PROGRAMS MAY BE PLACED INTO THIS SYSTEM.
THEREFORE, INFORMATION YOU PLACE ON THIS SYSTEM IS NOT PRIVATE.
USE OF THIS DOD COMPUTER SYSTEM, AUTHORIZED OR UNAUTHORIZED, CONSTITUTES
CONSENT TO OFFICIAL MONITORING OF THIS SYSTEM. UNAUTHORIZED USE OF A DOD
COMPUTER SYSTEM MAY SUBJECT YOU TO CRIMINAL PROSECUTION. EVIDENCE OF
UNAUTHORIZED USE COLLECTED DURING MONITORING MAY BE PROVIDED TO APPROPRIATE
PERSONNEL FOR ADMINISTRATIVE, CRIMINAL OR OTHER ACTION. |
Message as such is not only to scare people away, but also protect your legal grounds.
Yeah, I know it's the most boring welcome message you'd prefer.  |

when people telnet or ssh into your system, they don't have anything but a vt100 or ansi terminal. So, the issue.net file is shown instead of issue.
That simply copies the issue to issue.net, making them identical.
If you don't do anything fancy that only works on direct console, then that's alright. (I haven't found anything that I do)
or if you wanna warn people that they are being monitored when coming in from the net, the issue.net is where ya do it. |

If you would like to make a nice message on boot you need to edit the .bashrc file found in the users ~. I have no idea if there is a global one to. :D

Well...for a global boot message, that's what this thread seems to be about...
...but as you used the term "users" in your post, I'll assume that you mean that you want a login message - a message displayed for all users when they log in...
...and that's as simple as editing your /etc/motd file. If it doesn't exist, create one and...voila...when you log in...you get the Message of the Day... |

Have you tried making the first line read #!/bin/bash instead of #!/bin/sh ?
I have no idea if that will help.

As long as you have:
# Source global definitions
if [ -f /etc/profile ]; then
. /etc/profile
fi
in your .bashrc file within the home directories you will grab the global settings in /etc/profile

|
|
The Gentoo release version is ofcourse already available on your system. Therefor you can just parse the /etc/gentoo-release file and add it to your Linux_Logo 
| Code: |
#!/bin/sh
# Local system initialization script
/usr/bin/clear >> /etc/issue
COLOR1="\033[1;6m\033[32;40m" # bright green on black
COLOR2="\033[1;6m\033[34;40m" # bright purple on black
COLOR3="\033[1;6m\033[31;40m" # bright red on black
COLOR4="\033[1;6m\033[33;40m" # bright yellow on black
COLOR_RESET="\033[0m" # reset colours
rm -f /etc/issue
/usr/bin/linux_logo -L 3 -f -t "`cat /etc/gentoo-release`" >>/etc/issue
echo -e $COLOR_RESET >>/etc/issue
cp -f /etc/issue /etc/issue.net
|
It really isn't that much harder to display the Gentoo release version in several colours if you for example use awk/gawk to parse the gentoo-release file, but personally I liked this method best. |

| I love this, however I don't really see the point in an uptime message if the computer is a server and not logged into much, as it only updates if you login then log back out, all my terminals all show different uptimes |

|
|
So, here goes my first Gentoo forum post! 
I was playing around tonight and knocked up my own little /etc/issue script, which creates a little purple "g" Gentoo logo and a few lines of relevant banner text. Obviously, feel free to hack and improve it as you want....
[code]
#!/bin/bash
# AL's custom console greeting script for Gentoo Linux
# This will overwrite /etc/issue at every boot. So, make any changes you
# want to make to /etc/issue here or you will lose them when you reboot.
if [ -f /etc/gentoo-release ]; then
printf "\e[2J\e[H" > /etc/issue
R=$(cat /etc/gentoo-release | awk '{ print $5,$6 }')
C=$(cat /proc/cpuinfo | grep 'el na' | awk '{ print $5,$6,$7 }')
K=$(uname -r)
H=$(/bin/hostname -f)
M=$(( `dmesg | grep "Dentry" | awk '{print $9}'` / 1024 ))
KS=`dmesg | grep "Swap" | awk '{print $3}'`
S=$(( ${KS%k} / 1024 ))
DARK="\033[1;30m" # dark grey
GREY="\033[0m" # default grey / white
WHITE="\033[1;37m" # bright / bold white
PURPLE="\033[0;35m" # purple
BR_GREEN="\033[1;32m" # bright green
BR_BLUE="\033[1;34m" # bright blue
echo -e "$PURPLE _,-=-." >> /etc/issue
echo -e "$PURPLE ( \`. $BR_GREEN Gentoo$BR_BLUE Linux$GREY release $R" >> /etc/issue
echo -e "$PURPLE \`\\\\\ () ) $GREY Kernel$WHITE $K" >> /etc/issue
echo -e "$PURPLE > /' $GREY $C processor" >> /etc/issue
echo -e "$PURPLE /' ,/' $GREY"$M"Mb memory / "$S"Mb swap" >> /etc/issue
echo -e "$PURPLE (__.=~ $DARK ______________________________________$GREY" >> /etc/issue
echo "" >> /etc/issue
fi
[/code]
Hope it works for you - enjoy!

Very simple trick. Makes the cow say a fortune cookie.
| Code: | | echo -e "$(cowsay "$(fortune)")" >> /etc/issue |
I thought it was nice

and i added "5 * * * * /etc/init.d/issue" to my crontab to update the uptime and fortune every 5 minutes.
Note: The /proc/cpuinfo says Athlon(tm) Processor so i don't have to manually add "processor" to the script, maybe for your cpu you will have to add it.

I think that the crontab line you're looking for is */5 * * * * /etc/init.d/issue which will run the /etc/init.d/issue script every five minutes. The line you have will run the script every hour at five past.

lol! no, it wasn't a command. you actually want to type:
| Code: | | chmod 755 /etc/init.d/issue |
that will make the file /etc/init.d/issue executable

Ok, I'm having a bit of difficulty setting this up. Here is the process I took:
| Code: |
touch /etc/init.d/motd (message of the day)
nano -w /etc/init.d/motd
|
At this point I copied the entireity of the nice gentoo image and processor specs, etc word for word. (The poster escapes me atm)
I also used chmod 755 /etc/init.d/motd then copied that to /etc/motd. However, it prints out EXACTLY the text with all the code as well. It doesn't parse it. Any ideas??

EDIT: My mistake, I had #!/bin/sh instead of #!/bin/bash...now the error I get is
