Programming :: Script To Generate SSH Banner MOTD?
Apr 18, 2010
I want to automate my System-installation. So i try to make a Script that will generate the /etc/motd. Now i have the Problem that the script has some variables and after the "Hostname, OS, HW, IP" the "stars" are anyware, but not there they should. The most problem is the $OS this string can verry long or verry short be. Fedora release 12 (Constantine) or RedHat 5.4 i can do that after the variables place the "stars" on the write position?
Script
Code:
#!/bin/bash

Does anybody know how to generate excel charts from C, or if it's possible at all?
For example, if I had 2 arrays that I wanted to export to excel and graph against each other. I know how to export it to a csv file, that's no problem, but I have no idea where to start with generating a graph of the data. I can't seem to find any examples anywhere.
I'd appreciate if someone could point me in the right direction.
Just a simple example to show you what I mean code...

I have a file, two columns, first column has a list of 15000 (yes 15k) unique codes, second column has the afilliate codes of 60 locations repeated to fill out the 15000 rows of unique codes. I need to produce a nice neat paper voucher which will fit onto A6 (1/4 A4) and is ready to print. Each voucher has the unique code and corresponding location. So far I am thinking PHP will do the job. This does it somewhat, but doesn't let be split the fields between the ",". I did this so far in PHP

A script to generate random dates. It uses the year range 2006-2009, and truncates every month of the year to an ordinary February's 28 days, but otherwise it's pretty solid and safe.
Code:
spate=1
while [ $spate -le 120 ]

I have both 32 bit and 64 bit libs installed with gcc multilib.
I tried following options, but the result is still a 32bit elf:
# cc -mips64 -mabi=o64 -mlong64 -mgp64 -c gendian.c
# file gendian.o
gendian.o: ELF 32-bit LSB relocatable, MIPS, MIPS64 version 1 (SYSV), with unknown capability 0xf41 = 0x756e6700, with unknown capability 0x70100 = 0x1040000, not stripped
The machine is running 64 bit os:
# uname -a
Linux debian 3.2.0-4-5kc-malta #1 Debian 3.2.63-2+deb7u2 mips64 GNU/Linux
Both 4.6 and 4.7 gcc have been tried, and both have the same issue.
Fixed: need -mabi=64

i have spotted that script (something similar that i am looking for)
[URL]
and i just dont know how to use it.I am not a programmer myself and probably no need for learning that just to create one script! modify "wje_lq" script and run it. thing like : "Just redirect standard output to a file in the normal manner" ? and all this
I.Comment out the first definition of *character-set*, by adding a semicon at the beginning of the line.
II.Uncomment the second definition, which just uses "ABC", by removing the semicolon from the beginning of the line.
III.Comment out the first definition of *word-length*.
IV.Uncomment the second definition, which uses a word length of four.
i would like to generate :
10-character combinations of the following characters (lowercase) 23456789abcdef with no more then 3 same letters repeates no metter side by side or within one line (sequence) so lets say
abcdef1234 accept
fabcde1234 accept
ffabcd1234 accept
which is probably permutation with repetable string ( where abc is not equeal to cba etc .so ti speak position does metter)
fffabc1234 not acceptable -----(3 same characters)
ffabcf1234 not acceptable -----( 3 same characters event thought not side by side)
we dont want 3 same characters apper in same line.

[On Ubuntu 10.10 64-bit]
I have been trying to get rid of the boring motd when ssh-ing into the machine. I have sudo vim-ed the /etc/motd file to no avail.
Even if I add a motd.tail tail file with my content. I still get the boring and verbose:

I am setting a customized MOTD, however after 24 hrs, it reverts back to the default MOTD.
I noticed that it is a softlink
Code:
cmmiller@ladytron:/etc$ ls -al | grep motd
lrwxrwxrwx 1 root root 13 2009-07-05 10:47 motd -> /var/run/motd
cmmiller@ladytron:/etc$
And I'm making the change to /var/run/motd, however it keeps changing.

I applied some changed to the MOTD in /etc/update-motd (including removing the canonical mention in ./python2.6/dist-packages/landscape/sysinfo/landscapelink.py). After updating the system I found that all my changes had been deleted without any warning. Is there a way around this nonsense?

I am not sure what happened here. I have 10.04.1 and was able to run a command "update-motd". I wasn't able to get it to dynamically create a new motd. My hope was to have it recreate it once a day and email me the MOTD from the server.
In trying to get it to do this, I did a "apt-get install update-motd" in which it proceeded to do this, but then after the installation, I get:
"update-motd: command not found".
What did I do, how can I manually update/create the /var/run/motd file?

I'm just messing around trying to create a script that will give me a menu driven method of selecting a file from a directory. After doing some searching around on the web, I found that the "dialog" command might be able to provide what I need, but I'm not sure exactly if what I want is possible.
I was messing around with the --menu option and am getting pretty close, but not exactly what I want. Here's a snip of what I've been working with:
Code:
This gets me the results I want for the first option in the list, but the rest comes out a bit weird, as it's taking the directory contents and applying to the "tag" field as well. In fact, if there wasn't a need for the tag field, it would probably be working exactly as I want it to.
I plan on messing around a bit more to see if there is a workaround, but figured I'd post this just in case someone else had accomplished something similar. Essentially, this will be embedded in a script where each file in my $DIR variable will show in the menu and the selected file will end up in a variable for later use.

I know this is somewhat lame, but I remember back in college the MOTD on some of the systems was a random quote. I always wanted to do that. It seemed really trivial, but still neat and clever.
I searched a bit and don't see anything built-in for CentOS, so I was considering writing a Perl script to parse the RSS feed from a quotes site, then update /etc/motd with a random quote from the feed. This would nearly guarantee I could have this on any distro with identical results. Does anyone know of anything that already exists? Is anyone interested in using a script that I write to have the MOTD updated with random quotes themselves, or am I the only one? I'm perfectly willing to share the result when I'm finished.

I performed an apt-get upgrade and now my SSH Welcome Banner looks like the following. You'll notice that the banner repeats itself. The bottom half is acutally "static" and doesn't change. The top part is what I would normally see. How do I remove the bottom portion of the banner? Or modify the banner? Using Ubuntu Server 10.04 LTS

My F12 is connected to a Xerox DC432 printer on the network. The problem I'm facing is that banner sheet cannot be disable. The configuration setting on Administration->Printing showed that banner is off by default. "/etc/cups/printers.conf" file also have "JobSheets none none". I had the same problem with F11. Is there any step I'm missing? It doesn't seem to be problem of the printer itself because I could do this on a Windows OS.
