Use your Samsung Galaxy Y as Internet Access Point

One of the cool features of the Samsung Galaxy Y that is not to be found in other and older Galaxy smartphones in its class is the ability to share it's 3G internet connection to other Wi-Fi enabled devices like laptops, tablets and smartphones. This feature is commonly found on higher end Samsung Galaxy tabletss and smartphones but it is a nice treat from Samsung to have it included in this entry level Android phone.

I had a previous post of similar topic in this blog but that one deals with the Samsung Galaxy Tab. Since the naming of the feature in the menu is vastly different from that of Samsung Galaxy Tab, I took the liberty to post this one specifically for the Samsung Galaxy Y.

Having a personal Wi-Fi hotspot in your possession wherever you go offers lots of convenience to people who prefer using their laptop in browsing the internet and reading and sending email, in the absence of Wi-Fi access points in their location or even at home without regular internet  connection.

Once you activate the feature, other people can connect to your Samsung Galaxy Y and use its 3G internet connection to browse the Internet. The only downside of this feature is the maximum number of concurrent users which is set to 5 only.

To make sure that only people whom you authorize to connect will be able to use the service, you have the option to set WPA-PSK security in your device. meaning, you can set a passphrase or password which you can share with your users prior to connection just like in a dedicated Wi-Fi router/access point.

The procedure is very simple and outlined below:

1. Go to "Settings" and tap on "Wireless and Networks",

2. Tap on "Tethering and portable hotspot",

3. Tap to check the "Portable Wi-Fi Hostspot",

4. As soon as you see the "Portable Wi-Fi- hotspot AndroidAP7711 active" below the "Portable Wi-Fi hotpsot, you and your users can already connect to the Galaxy Y Access Point using your various devices but in this instance, the connection is "Open" and unsecured. What you have to do to enable security is  tap on the "Configure Portable Wi-Fi hotspot" after which you will have the option of setting your own Network SSID or leave the default "AndroidAP7711". Click on "security" below the Network SSID and choose WPA2 PSK in the dropdown list. Input your password or passphrase and you're good to go.

 By the way, before you do the above-mentioned things, make sure that your phone has enough load credits if you are on prepaid cellular service and that your network's APN is properly configured to browse over 3G. If you can browse the internet on your Galaxy Y prior to setting up the Access Point, then you will have no problem. If you cannot access the internet, check on your 'Mobile Networks Settings" and see if the "Use Packet Data" is checked or activated. This setting determines your phones capability to access the internet given enough  load credits and proper APN configuration.

In my case, prior to doing these things, I subscribe first to a day's unlimited internet with my Mobile Network or cellular provider to enjoy unhampered browsing with my pals and family members.

Snmpd filling up /var/log/messages

At work we have a central monitoring system for servers called Cacti, this uses standard snmp connections to servers to get their status, disk usage, CPU performance.

On my CentOS linux servers the standard snmpd daemon works well with Solarwinds but the monitoring server seems to make a lot of connections to the system and each one gets logged via the syslog daemon to /var/log/messages giving rise to lots of lines saying things like

snmpd[345435]: Connection from UDP: [10.225.46.136]:135                

last message repeated 8 times
last message repeated 13 times

These are only information messages saying a connection has been established. This is rather annoying when you are trying to read other things in /var/log/messages. The way to turn off these messages is to change the logging options of the snmpd daemons.
On Redhat ( and Ubuntu) the default logging ( the -L options ) show:–

-Ls d

Meaning log to syslog using the facility of daemon ( see syslogd and syslog.conf for more information on what that means in detail, for now suffice it to say it means all messages are written to /var/log/messages ).
The man pages for snmpcmd ( common to all net-snmp programmes ) explain you can set this to only log messages above a certain priority.
Using priorities 0-4 means warning messages, errors, alerts and critical etc messages are logged but notice info and debug level messages are ignored.
The manual pages are not that clear, to me at least at first, hence this blog.
So if we change the -Ls d to the following this will stop those messages but still allow important messages to get through:–

LS 0-4 d

The capital S is crucial to the syntax.
So where and how do we set these options? Well the snmpd daemon is started by a standard init script /etc/init.d/snmpd
In both RHEL5 and Ubuntu the scripts have some default options but also read in settings from a config file. In Ubuntu the relevant portion of the script is:-

SNMPDOPTS=’-Lsd -Lf /dev/null -p /var/run/snmpd.pid’
TRAPDRUN=no
TRAPDOPTS=’-Lsd -p /var/run/snmptrapd.pid’
#Reads config file (will override defaults above)
[ -r /etc/default/snmpd] && . /etc/default/snmpd

So this sets the variable SNMPDOPTS to the default value and then if the file /etc/default/snmpd is readable it “sources” the content of that file.
Thus if /etc/default/snmpd contains the line

SNMPDOPTS='-LS 0-4 d -Lf /dev/null -p /var/run/snmpd.pid'

Then stopping and starting the snmpd daemon will make it run with the new logging options we want.

sudo /etc/init.d/snmpd restart

In RHEL5 the equivalent file is /etc/snmp/snmpd.options and the equivalent variable is OPTIONS rather than SNMPDOPTS
Now there could be security implications to not recording the IP address of every SNMP request on your server in case some other system is connecting that shouldn’t be, but there are ways with community strings and other authentication options for SNMP to reduce the risk of that.
All in all the I think the risk of missing an important message in /var/log/messages outweighs the risks from not logging the snmpd messages.

Using Mutt to send email

Mutt is a popular email client (MUA) which is common on Linux systems.

Given below are some how-tos on basic uses of mutt. For all UNIX utilities, the "man pages" are your best bet to learn them. I’ve just documented some popular uses of mutt. Refer the "man pages" for a more comprehensive understanding of mutt. The commands below have been tested on Red Hat Enterprise Linux 4.0 AS Update 7 with mutt v1.4.1i, unless otherwise stated.

HOW-TO 1: Send email with blank/empty body

mutt -s "Test email" testmail@abc.com < /dev/null
#
# where:
# -s => Subject
# testmail@abc.com => recipient's email address
#

HOW-TO 2: Send email with body read from a file

mutt -s "Test email" testmail@abc.com < email_body.txt
#
# where:
# -s => Subject
# testmail@abc.com => recipient's email address
# email_body.txt => file containing message body
#

HOW-TO 3: Send email with a customized sender name and email address

# The .muttrc file is Mutt's configuration file. It's default location is the $HOME directory.
# If you locate it elsewhere, specify its location with the '-F' flag.
# Add the following to the .muttrc file:
set realname="Joe Bloggs"
set from="noreply@jb.com"
set use_from=yes
#
# where:
# realname => Sender's name as it appears in the recipient's mail inbox.
# from => the "reply-to" address
# 

After configuring .muttrc, send emails as per how-tos 1 and 2.

HOW-TO 4: Send attachment(s)

mutt -s "Test email" -a file1 -a file2 testmail@abc.com < /dev/null
#
# where:
# -s => Subject
# testmail@abc.com => recipient's email address
# file1 => first attachment
# file2 => second attachment
#

HOW-TO 5: Send HTML email

I know that the technical purists out there abhor HTML emails due to potential issues with accessibility and security, but hey, there’s no denying the fact that HTML-formatted emails are far more interesting to look at than plain-text email and are better at drawing your attention to specific information (ask the marketing guys and senior executives!). HTML-formatted emails are supported by Mutt versions 1.5 and higher. Here’s how you may send an HTML-formatted email using mutt v1.5.21:

mutt -e "set content_type=text/html" -s "Test email" testmail@abc.com < welcome.html
#
# where:
# -s => Subject
# testmail@abc.com => recipient's email address
# -e => command to execute
# content_type => email body MIME type
#

The MIME type multipart/alternative ensures your emails are received properly by both plain-text and HTML clients, but it does not work well with mutt at present.

MySQL Table is marked as crashed and last (automatic?) repair failed

If you have a table in mysql that has crashed and your attempts to repair it using mysqlcheck have failed, then you may have to resort to the lower level myisamchk command.

To use this, you will need to stop the server process (usually service mysqld stop or /etc/init.d/mysqld stop) and then find the data files (usually in /var/lib/mysql/databasename).

You can then run the following command against the table:

myisamchk -r -v -f --sort_buffer_size=128M --key_buffer_size=128M /var/lib/mysql/database/table.MYI

Obviously replacing database/table with the correct database and table.

MySQL Error: Client requested master to start replication from impossible position

Error reading packet from server: Client requested master to start replication from impossible position (server_errno=1236)

Got fatal error 1236: 'Client requested master to start replication from impossible position' from master when reading data from binary log 

This might happen, for example, if there is a power failure on the master and it is unable to write out all the transactions to the replication log.

The proper way to fix it

Start replication all over.  Follow normal instructions on taking the main database down, record the master position, make a snapshot, copy it over to slave, start things back up, etc.

A more lazy clever approach

Assmption:  Lets assume that your slave was up-to-date with the master when things went sour.  This should usually be the case on a properly-configured not-overly-loaded replication setup.

First, lets look at the master status on the master:

mysql> show master status;
+----------------+----------+--------------+------------------+
| File           | Position | Binlog_do_db | Binlog_ignore_db |
+----------------+----------+--------------+------------------+
| box162-bin.014 | 29510700 |              |                  |
+----------------+----------+--------------+------------------+
1 row in set (0.00 sec)

Okay, lets assume that when you rebooted the master or brought it back up after the power failure, that it will have started this new log, number 014.

My slave was stuck on number 013, and giving the "Client requested master to start replication from impossible position" error.

How to fix?  Well, again, with the big assumption that the slave was generally up-to-date anyway, I simply went to the slave and did:

slave stop;
CHANGE MASTER TO MASTER_HOST='sunabc.net', MASTER_USER='repluser',MASTER_PASSWORD='replPass', MASTER_LOG_FILE='mysql-bin.000005', MASTER_LOG_POS=0
slave start;

And there we have it!  The slave will start replicating on the new file.  When power goes out and you have incomplete replication logs like this, we're really hoping that things are close enough in sync that this works.

Just do a "show slave status" on your slave, and make sure Slave_IO_Running and Slave_SQL_Running both say yes.

If you get errors about duplicate keys or other SQL inconsistency, then sorry, you were not as lucky this time.  Do the normal backup.

RAID 0, RAID 1, RAID 5, RAID 10 Explained with Diagrams

RAID stands for Redundant Array of Inexpensive (Independent) Disks.
On most situations you will be using one of the following four levels of RAIDs.

• RAID 0
• RAID 1
• RAID 5
• RAID 10 (also known as RAID 1+0)

This article explains the main difference between these raid levels along with an easy to understand diagram.

In all the diagrams mentioned below:

• A, B, C, D, E and F – represents blocks
• p1, p2, and p3 – represents parity

RAID LEVEL 0

 

Following are the key points to remember for RAID level 0.

• Minimum 2 disks.
• Excellent performance ( as blocks are striped ).
• No redundancy ( no mirror, no parity ).
• Don’t use this for any critical system.

RAID LEVEL 1

Following are the key points to remember for RAID level 1.

• Minimum 2 disks.
• Good performance ( no striping. no parity ).
• Excellent redundancy ( as blocks are mirrored ).

RAID LEVEL 5

 

Following are the key points to remember for RAID level 5.

• Minimum 3 disks.
• Good performance ( as blocks are striped ).
• Good redundancy ( distributed parity ).
• Best cost effective option providing both performance and redundancy. Use this for DB that is heavily read oriented. Write operations will be slow.

RAID LEVEL 10

 

Following are the key points to remember for RAID level 10.

• Minimum 4 disks.
• This is also called as “stripe of mirrors”
• Excellent redundancy ( as blocks are mirrored )
• Excellent performance ( as blocks are striped )
• If you can afford the dollar, this is the BEST option for any mission critical applications (especially databases).

Install RRDTool on Red Hat Enterprise Linux

RRD is the Acronym for Round Robin Database. RRD is a system to store and display time-series data (i.e. network bandwidth, machine-room temperature, server load average). It stores the data in a very compact way that will not expand over time, and it presents useful graphs by processing the data to enforce a certain data density. It can be used either via simple wrapper scripts (from shell or Perl) or via frontends that poll network devices and put a friendly user interface on it.

Installing RRDTool on RHEL

In order to install RRDTool on Red Hat Enterprise Linux / CentOS Linux 64 bit version you need to install few development tools and libraries.

Step # 2: Download latest rrdtool tar ball

Type the following commands:
# cd /opt/
# wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.3.1.tar.gz
Untar tar ball, enter:
# tar -zxvf rrdtool-1.3.1.tar.gz

Step #3: Compile and install rrdtool

You need to set PKG_CONFIG_PATH, enter:
# export PKG_CONFIG_PATH=/usr/lib/pkgconfig/
Type the following commands:
# ./configure
Sample output:

config.status: executing default-1 commands
config.status: executing intltool commands
config.status: executing default commands
config.status: executing po/stamp-it commands
checking in... and out again
