BusyBox

The Swiss Army Knife

of

Embedded Linux

SYNTAX
busybox [arguments...] # or
[arguments...] # if symlinked
DESCRIPTION
BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides minimalist replacements for most of the utilities you usually find in GNU coreutils, util-linux, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts.
BusyBox has been written with size-optimization and limited resources in mind. It is also extremely modular so you can easily include or exclude commands (or features) at compile time. This makes it easy to customize your embedded systems. To create a working system, just add /dev, /etc, and a Linux kernel. BusyBox provides a fairly complete POSIX environment for any small or embedded system.
BusyBox is extremely configurable. This allows you to include only the components you need, thereby reducing binary size. Run 'make config' or 'make menuconfig' to select the functionality that you wish to enable. Then run 'make' to compile BusyBox using your configuration.
After the compile has finished, you should use 'make install' to install BusyBox. This will install the 'bin/busybox' binary, in the target directory specified by CONFIG_PREFIX. CONFIG_PREFIX can be set when configuring BusyBox, or you can specify an alternative location at install time (i.e., with a command line like 'make CONFIG_PREFIX=/tmp/foo install'). If you enabled any applet installation scheme (either as symlinks or hardlinks), these will also be installed in the location pointed to by CONFIG_PREFIX.
USAGE
BusyBox is a multi-call binary. A multi-call binary is an executable program that performs the same job as more than one utility program. That means there is just a single BusyBox binary, but that single binary acts like a large number of utilities. This allows BusyBox to be smaller since all the built-in utility programs (we call them applets) can share code for many common operations.
You can also invoke BusyBox by issuing a command as an argument on the command line. For example, entering
/bin/busybox ls
will also cause BusyBox to behave as 'ls'.
Of course, adding '/bin/busybox' into every command would be painful. So most people will invoke BusyBox using links to the BusyBox binary.
For example, entering
ln -s /bin/busybox ls ./ls
will cause BusyBox to behave as 'ls' (if the 'ls' command has been compiled into BusyBox). Generally speaking, you should never need to make all these links yourself, as the BusyBox build system will do this for you when you run the 'make install' command.
If you invoke BusyBox with no arguments, it will provide you with a list of the applets that have been compiled into your BusyBox binary.
COMMON OPTIONS
Most BusyBox applets support the --help argument to provide a terse runtime description of their behavior. If the CONFIG_FEATURE_VERBOSE_USAGE option has been enabled, more detailed usage information will also be available.

LIBC NSS
GNU Libc (glibc) uses the Name Service Switch (NSS) to configure the behavior of the C library for the local environment, and to configure how it reads system data, such as passwords and group information. This is implemented using an /etc/nsswitch.conf configuration file, and using one or more of the /lib/libnss_* libraries. BusyBox tries to avoid using any libc calls that make use of NSS. Some applets however, such as login and su, will use libc functions that require NSS.
If you enable CONFIG_USE_BB_PWD_GRP, BusyBox will use internal functions to directly access the /etc/passwd, /etc/group, and /etc/shadow files without using NSS. This may allow you to run your system without the need for installing any of the NSS configuration files and libraries.
When used with glibc, the BusyBox 'networking' applets will similarly require that you install at least some of the glibc NSS stuff (in particular, /etc/nsswitch.conf, /lib/libnss_dns*, /lib/libnss_files*, and /lib/libresolv*).
Shameless Plug: As an alternative, one could use a C library such as uClibc. In addition to making your system significantly smaller, uClibc does not require the use of any NSS support files or libraries.

Introduction to irc or internet relay chat

noreply@blogger.com (mike groovy) — Wed, 20 Jul 2016 10:40:00 +0000

What is Internet Relay Chat???

"well, for the boring parts, I'll quote Wikipedia to save time",

the IRC Protocol (IRCP) is an application layer protocol that facilitates communication in the form of text. The chat process works on a client/server networking model. IRC clients are computer programs that a user can install on their system.

These clients communicate with chat servers to transfer messages to other clients. IRC is mainly designed for group communication in discussion forums, called channels, but also allows one-on-one communication via private messages as well as chat and data transfer, including file sharing

Yeah, so in other words you can chat up the world, constructed only by your language skills and reference book's own table of contents.

though if your haven't already ever been an irc user, chances are it's making your head hurt, giving second thoughts or for you curious cats, it's kicking in that catnip u took a while ago thank my stars! lol I'm just joking gotta be a loon when your living in a loonie land! nough bout that
so for starter, your gonna wanna attempt to communicate so download a pdf of irc commands or check out the next section...

Here are some of the more common IRC commands that we use often. For a far more complete list, please visit our mIRC Commands page.

/join
Type /join #channelname -- to join a channel of your choice
Example: /join #bossmom
What it looks like:

[18:44] *** Now talking in #beginner
--Op-- bossmom has joined the channel
[18:44] *** Topic is 'Beginner's Help/Chat Channel....All Are Welcome Here!! ®© [ENGLISH]'
[18:44] *** Set by X on Sun Jul 23 16:10:34
/me
The /me is an action message.
Type /me 'does anything'
Example: /me waves hello
What it looks like:
* bossmom waves hello
/msg
Type /msg nickname (message) to start a private chat.
Example: /msg puddytat Hey tat, how are you?
What it looks like:
-> *puddytat* Hey tat, how are you?
/nick
/nick changes your nickname
Example: type /nick newnickname (limit 9 characters)
What it looks like: I typed /nick luv2quilt
*** bossmom is now known as luv2quilt
/notice
A notice is used to send a short message to another person without opening up a private window.
Type /notice nickname (message)
Example: /notice badnick Please change your nickname for this family channel.
What it looks like:
-> -badnick- Please change your nickname for this family channel.
/part
Type /part -- to leave one channel
Type /partall -- to leave all the channels you are in
/ping
Type /ping nickname. What this command does is give you the ping time, or lag time, between you and the person you pinged. Lag can be explained as the amount of time it takes for you to type your message and for others to read your messages. Unfortunately, lag is always a part of IRC, although most times it's not a problem, just a nuisance.
Example: /ping luv2quilt
What it looks like:
[19:04] -> [luv2quilt] PING
[19:04] [luv2quilt PING reply]: 0secs
/query
Similar to the /msg, except it forces a window to pop open.
Type /query nickname (message)
Example: /query Sofaspud^ Sooo....what's new?
What it looks like:
<luv2quilt> soooo....what's new?
/quit
Type /quit to leave IRC altogether. This disconnects mirc from the server.
Example: /quit Going out for dinner...nite all
What it looks like:
*** Quits: saca (Leaving)
/ignore
Unfortunately, there will be times when you don't want to talk to someone, or else someone may be harassing you.
By typing /ignore nickname 3, you will not receive anymore messages from that person.
Example: /ignore luv2quilt 3
To Unignore them, type /ignore -r luv2quilt 3
What it looks like:
*** Added *!*bossmom@*.dialup.netins.net to ignore list
*** Removed *!*bossmom@*.dialup.netins.net from ignore list
/whois
Type /whois nickname to see a bit more information about another user. You'll see what server another person is using, or what their ISP is. Pretty helpful when you don't recognize a nickname that wants to chat. You may recognize the IP, (Internet Protocol) and then feel more comfortable carrying on a conversation. You'll also be able to see what other channels a person is in, which might be a good indicator if you really want to talk with them or not.
Example: /whois bossmom
What it looks like:
luv2quilt is bossmom@elwo-01-094.dialup.netins.net * Enjoy the Journey........
luv2quilt on @#bossmom
luv2quilt using Seattle.WA.US.Undernet.org the time for school is during a recession.
luv2quilt has been idle 18secs, signed on Sun Jul 23 18:47:26
luv2quilt End of /WHOIS list.
/chat
This opens up a DCC/CHAT window to another user. What's nice about these is that you can continue to chat even if you get disconnected from your server.
Word of Caution: Do NOT accept dcc/chats nor dcc/gets from anyone that you don't know.
Type /chat nickname.
Example: /chat oddjob^
What it looks like:
Chat with oddjob^
Waiting for acknowledgement...
/help
There's one more very helpful command, and probably the one you'll use a lot when first starting out. In fact, I still use it quite a lot, and that's the built-in help menu of mIRC.
Type /help, you'll see the the mIRC Help Menu open up. You can do a search from there, or you can type /help topic. Either way, a TON of information at your fingertips.
Example: /help Basic IRC Commands

With that info under the belt, you are ready to setup your IRC client.
<a href="http://www.ircbeginner.com/ircinfo/mirc.html">all about mirc client for windows</a><br>

Nows a Good idea to brush up on and to test out your proficiency and ability on where and how to locate other users of irc networks, web groups, irc channels-Channel names appear in text as such, #channel
just try a search on Google for
intext:#***
or irc channels freenode mirc ect

And if that's not enough,
here are some tips
and tricks to help out.
<HR>
The @ in Front of a Person's Nick
When you join a channel and see folks with the @ in front of their nickname, this means that they are an Op, or Operator of the channel. These folks help maintain order, and in #Beginner, we also are the helpers/teachers that welcome the newcomers to the wild and wacky world of IRC. Ops have the abilities to kick, and/or ban out a user that's misbehaving. Every channel has it's own rules, and the Undernet Administrators generally do not interfere with channel politics. You can check here for more information about being an Op in #Beginner.
Abbreviations used on IRC
If you spend anytime on IRC at all, you'll begin to notice letters strung together and not making any sense. As folks spend more time typing, they find ways to shortcut certain phrases, or sentences. For instance: bbl = be back later, brb = be right back, btw = by the way, np = no problem, lol = laugh out loud, rofl = rolling on the floor laughing, wb = welcome back, gmta = great minds think alike, focl = falling off chair laughing, j/k = just kidding, ttyl = talk to you later, ltns = long time no see...etc, etc. Check here for an Abbreviation Chart.
Channels
Channels are places that people go to for chat, help, to report problems, etc. There are many available, and once you find a group of people that you strike common bonds with, it's fun to keep up with them, and their lives. Channels operate much like a company. For every registered channel, channels with an X bot, there is a Channel Manager, Assistant Managers, Senior Ops, Operators and those with Voice. Note: a Bot = a program that helps to maintain order in the channel, and gives the channel operators the @. You can create your own channel by typing /join #channelname. If the channel is not registered or being used already, then you will have the @ (Operator) there.
We have put together a List of Helpful Channels. You may find something along your interest level there.
Emoticons
Sometimes as you're typing, you'll see folks use :), or ;), or ;-), or =^;^=, or maybe even :P. All of these signify a facial expression. For instance, the first few are smiley faces, this one: =^;^= is used by a person who's nickname is puddytat. The :P is someone sticking out the tongue. :( would be a frown, :0 would be "Oh my gosh!".....well, I think you get the idea. ;) Worth the click -- tons more Emoticon Listing.
Netiquette
There are certain rules of etiquette for chatting on IRC, usually called 'Netiquette', and if you'll follow a few rules of common courtesy, you'll find your stay quite enjoyable. TYPING IN ALL CAPS is usually viewed as shouting, and not recommended if you wish to continue to participate in a channel. Using foul language, or being rude to others is also discouraged on most channels. If you join a channel and find it offensive, simply leave, there are thousands of others to choose from. You can check here for a more complete listing of Netiquette Do's and Don'ts.
Ping? Pong!
Now, once you're logged on, and ready to chat, you might notice some strange looking things in your status window (the window you are in when you logon). The Ping? Pong! is simply your server sending a command (Ping?) to your client, and when your client automatically answers with a Pong!, it's just saying, "Yes, I'm here, don't disconnect me". :) When a server is unable to get a PONG! response, you will be disconnected since the server thinks you are not there. When servers are unable to keep alive the communiations with the other servers, then it will 'split', eventually rejoining the group again. This is technically called a netsplit, and is an all-too-common occurance on the Undernet.
Pictures
I've been IRC'ing for almost four years (YOW!), and one of the things that I like best about it is that we can become friends with someone based totally on the written word. Over time, quite a bit can be discovered by watching how someone types, what their responses are, what kind of mood they are in, etc. After becoming friends with folks, it's a neat thing to then be able to see what they look like. Most of you have probalby heard of the term 'scanning' a picture. This means to have a computer scanner copy(scan) a picture onto a disk. These are typically called either a .jpg or a .gif file, and can be transferred from one computer to another computer with only the click of a mouse. Sending or receving a file through IRC uses the DCC option found on more IRC clients.
Sounds
Chatting isn't the only thing we can do while using IRC. Folks can PLAY sounds that are in their computers already, or can GET sounds from someone else by requesting them. To play a sound, the command is /sound wavename.wav. There are literally thousands of wavs available, which is the term used to describe a sound file. Not all channels allow wavs to be played, so just hang out, or ask one of the ops what their policy is on the playing of wavs. You can find a Sounds Tutorial here.

SO GOOD! Trader Joe's Mandarin Orange chicken.. yum!

noreply@blogger.com (mike groovy) — Tue, 19 Jul 2016 09:29:00 +0000

This dish was seriously good.

All I did was preheat the oven to 400 degrees for 10 mins, then place the chicken on a baking sheet for 17 mins.

twice during baking, I turned the pieces over to even out their cooking.

I also heated a sauce pan on the stovetop and emptied the sauce packets that came with the meal into medium/low heat and allowed to simmer but not burn.

Once the chicken was finished, I simply folded the meat into the sauce being careful not to soak and allow some crunch to remain intact..

A perfect 20 min meal, aThis dish was seriously good. All I did was preheat the oven to 400 degrees for 10 mins, then place the chicken on a baking sheet for 17 mins.

Configuring NIS Services in Linux

noreply@blogger.com (mike groovy) — Mon, 07 Dec 2015 21:52:00 +0000

Configuring NIS Services in Linux

What is NIS?

Network Information Service (NIS) is used for keeping a centralized repository of users, hostnames and other useful information in a computer network. In single server UNIX environments, the list of users and groups is usually kept in a file such as /etc/passwd. Using NIS adds a "global" directory which is used for authenticating users from any host on the network.

Note: In the early days, NIS was called Yellow Pages. The developers had to change the name after a copyright infringement lawsuit, yet many of the key programs associated with NIS have kept their original names beginning with yp.

Getting Started

This tutorial covers mostly RPM based distributions of GNU/Linux such as Red Hat, Fedora, or CentOS. There are also references to Debian based distrbutions such as Ubuntu. For information pertaining to your particular distrbution, please consult your documentation.

Defining the NIS Domain Name

Edit the /etc/sysconfig/network file

In Red Hat-based distributions need to add the NIS domain name we wish to use in the /etc/sysconfig/network file. For this example, we will call the domain "LINUX-NIS".
#/etc/sysconfig/network
NISDOMAIN="LINUX-NIS"

In Debian based distributions we would edit the /etc/defaultdomain file and simply put in the NIS domain name
#/etc/defaultdomain
LINUX-NIS

Also, in Debian-based distributions, we would edit the /etc/default/nis file and configure this as a Master NIS server
#/etc/default/nis
NISSERVER=master

Both Linux distributions have a configuration file for YP. We need to edit our /etc/yp.conf file. NIS servers also need to be NIS clients themselves, so we will have to edit the yp.conf to point this file towards the server itself, or localhost.
# /etc/yp.conf - ypbind configuration file
ypserver 127.0.0.1

NIS Server Daemons

The following is a list of NIS server daemons and their functionality. We need to know these individual components in order to troubleshoot NIS issues later on.

DAEMON NAME

PURPOSE

portmap

The foundation service for RPC

yppasswdd

Allows users to change their NIS passwords

ypserv

NIS server daemon

ypbind

NIS client daemon

ypxfrd

The NIS map transfer daemon

Starting The NIS Server Related Daemons

We now need to start a couple of the NIS daemons in the /etc/init.d directory. In this case we will only be starting the portmap, yppasswdd, and ypserv daemons so that we can initialize the NIS domain.

On Red Hat we would issue the following commands:
[root@nis-server1]# /etc/init.d/portmap start
Starting portmapper: [ OK ]

[root@nis-server1]# /etc/init.d/yppasswdd start
Starting YP passwd service: [ OK ]

[root@nis-server1]# /etc/init.d/ypserv start
Setting NIS domain name LINUX-NIS: [ OK ]
Starting YP server services: [ OK ]

On Debian we would issue the following commands:
[root@nis-server1]# /etc/init.d/portmap start
Starting portmapper: [ OK ]

[root@nis-server1]# /etc/init.d/nis start
Setting NIS domainname to: LINUX-NIS
Starting NIS services: ypserv yppasswdd ypxfrd ypbind: [ OK ]

Note: The ypxfrd and ypbind daemons start with the all-encompassing nis startup script for Debian. These daemons will time out on starting due to the fact that the NIS domain has not been initialized yet. This is expected. NFS domain initialization is covered in the next section.

With Redhat-based distributions we would use the chkconfig command to configure these daemons to start after every reboot.
[root@nis-server1]# chkconfig portmap on
[root@nis-server1]# chkconfig yppasswdd on
[root@nis-server1]# chkconfig ypserv on

With Debian-based distributions we would simply invoke the update-rc.d command to configure these services to start at boot time
[root@nis-server1]# update-rc.d portmap defaults [ OK ]
[root@nis-server1]# update-rc.d nis defaults [ OK ]

We need to make sure these daemons are running before continuing to the next step. We can use the rpcinfo command to do this:
[root@nis-server1]# rpcinfo -p localhost
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100009 1 udp 681 yppasswdd
100004 2 udp 698 ypserv
100004 1 udp 698 ypserv
100004 2 tcp 701 ypserv
100004 1 tcp 701 ypserv

The ypbind and ypxfrd might be listed as running, even though they do not start properly until after the initialization of the NIS domain. If they are running, we will restart these daemons after the domain initialization is completed.

Initializing The NIS Domain

Now that we have decided on the name of the NIS domain, we will have to use the ypinit command to create the associated authentication files for the domain. We will be prompted for the name of the NIS server, which in this case is nis-server.
[root@nis-server1]# /usr/lib/yp/ypinit -m

At this point, we have to construct a list of the hosts which will run NIS servers. nis-server1 is in the list of NIS server hosts. We must continue to add the names for the other hosts, one per line. When we are done with the list, simply type "a".
next host to add: nis-server1
next host to add:
The current list of NIS servers looks like this:
nis-server1
Is this correct? [y/n: y] y
We need a few minutes to build the databases...
Building /var/yp/LINUX-NIS/ypservers...
Running /var/yp/Makefile...
gmake[1]: Entering directory `/var/yp/LINUX-NIS'
Updating passwd.byname...
Updating passwd.byuid...
Updating group.byname...
Updating group.bygid...
Updating hosts.byname...
Updating hosts.byaddr...
Updating rpc.byname...
Updating rpc.bynumber...

Updating services.byservicename...
Updating netid.byname...
Updating protocols.bynumber...
Updating protocols.byname...
Updating mail.aliases...
gmake[1]: Leaving directory `/var/yp/LINUX-NIS'
nis-server1 has been set up as a NIS master server.

Now we can run ypinit -s nis-server1 on all slave servers (If we have any slave servers).

Note: Make sure portmap is running before trying this step or you'll get errors, such as:
failed to send 'clear' to local ypserv: RPC: Port mapper failureUpdating group.bygid...

You will have to delete the /var/yp/LINUX-NIS directory and restart portmap, yppasswd, and ypserv before you'll be able to do this again successfully.

Start The ypbind and ypxfrd Daemons

On Redhat, you can now start the ypbind and the ypxfrd daemons because the NIS domain had been initialized and the files have been created.
[root@nis-server1]# /etc/init.d/ypbind start
Binding to the NIS domain: [ OK ]
Listening for an NIS domain server.
[root@nis-server1]# /etc/init.d/ypxfrd start
Starting YP map server: [ OK ]
[root@nis-server1]# chkconfig ypbind on
[root@nis-server1]# chkconfig ypxfrd on

On Debian, you would simply restart the /etc/init.d/nis service:
[root@nis-server1]# /etc/init.d/nis restart
Starting NIS services: ypserv yppasswdd ypxfrd ypbind

Verify The Daemons Are Running

All the NIS daemons use RPC port mapping and, therefore, are listed using the rpcinfo command when they are running correctly.
[root@nis-server1]# rpcinfo -p localhost
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs
100021 1 udp 1024 nlockmgr
100021 3 udp 1024 nlockmgr
100021 4 udp 1024 nlockmgr
100004 2 udp 784 ypserv
100004 1 udp 784 ypserv
100004 2 tcp 787 ypserv
100004 1 tcp 787 ypserv
100009 1 udp 798 yppasswdd
600100069 1 udp 850 fypxfrd
600100069 1 tcp 852 fypxfrd
100007 2 udp 924 ypbind
100007 1 udp 924 ypbind
100007 2 tcp 927 ypbind
100007 1 tcp 927 ypbind

Adding New NIS Users

New NIS users can be created by logging into the NIS server and creating the new user account. In this case, you'll create a user account called nisuser and give it a new password.

Once this is complete, you then have to update the NIS domain's authentication files by executing the make command in the /var/yp directory.

This procedure makes all NIS-enabled, nonprivileged accounts become automatically accessible via NIS, not just newly created ones. It also exports all the user's characteristics stored in the /etc/passwd and /etc/group files, such as the login shell, the user's group, and home directory.
[root@nis-server1]# useradd -g users nisuser
[root@nis-server1]# passwd nisuser
Changing password for user nisuser.
New password: ********
Retype new password: ********
passwd: all authentication tokens updated successfully.

[root@nis-server1]# cd /var/yp
[root@nis-server1]# make
gmake[1]: Entering directory `/var/yp/LINUX-NIS'
Updating passwd.byname...
Updating passwd.byuid...
Updating netid.byname...
gmake[1]: Leaving directory `/var/yp/LINUX-NIS'

You can check to see if the user's authentication information has been updated by using the ypmatch command, which should return the user's encrypted password string.
[root@nis-server1]# ypmatch nisuser passwd
nisuser:$1$d6E2i79Q$wp3Eo0Qw9nFD/::504:100::/home/nisuser:/bin/bash

You can also use the getent command, which has similar syntax. Unlike ypmatch, getent doesn't provide an encrypted password when run on an NIS server, it just provides the user's entry in the /etc/passwd file. On a NIS client, the results are identical with both showing the encrypted password.
[root@nis-server1]# getent passwd nisuser
nisuser:x:504:100::/home/nisuser:/bin/bash

From here you should be up and going with your new NIS domain. Have fun.
