The WordPress.com stats helper monkeys prepared a 2012 annual report for this blog.
Here’s an excerpt:
About 55,000 tourists visit Liechtenstein every year. This blog was viewed about 850,000 times in 2012. If it were Liechtenstein, it would take about 15 years for that many people to see it. Your blog had more visits than a small country in Europe!
If you want to use GMAIL as your sendmail relay server, Use the below configuration.
{I required it to send DMASOFTLAB RADIUS MANAGER Email notifications to all users regarding there service status, account expiry, renewal , various alerts and other info. that’s why I wrote this guide, it maybe useful for others too . . Syed Jahanzaib }
First install Sendmail and its utilities.
apt-get install sendmail mailutils
Now configure signed SSL certificates
mkdir /etc/mail/certs chmod 700 /etc/mail/certs cd /etc/mail/certs
openssl dsaparam 1024 -out dsa1024 -out dsa1024.pem
(It will ask you various questiosn , just enter them accordingly, like country code, for Pakistan its PK, and other information you have)
openssl req -x509 -nodes -days 3650 -newkey dsa:dsa1024.pem -out /etc/mail/certs/mycert.pem -keyout /etc/mail/certs/mykey.pem
(It will ask you various questions , just enter them accordingly, like country code, for Pakistan its PK, and other information you have)
openssl req -x509 -new -days 3650 -key /etc/mail/certs/mykey.pem -out /etc/mail/certs/mycert.pem
ln -s /etc/mail/certs/mycert.pem /etc/mail/certs/CAcert.pem chmod 600 /etc/mail/certs/* cd ..
nano /etc/mail/authinfo
AuthInfo:smtp.gmail.com "U:root" "I:USERNAME@gmail.com" "P:PASSWORD" AuthInfo: "U:root" "I:USERNAME@gmail.com" "P:PASSWORD"
Save & Exit & issue below command
makemap hash /etc/mail/authinfo < /etc/mail/authinfo
nano /etc/mail/sendmail.mc
dnl # dnl # SSL Settings define(`CERT_DIR', `MAIL_SETTINGS_DIR`'certs') define(`confCACERT_PATH', `CERT_DIR') define(`confCACERT', `CERT_DIR/CAcert.pem') define(`confSERVER_CERT', `CERT_DIR/mycert.pem') define(`confSERVER_KEY', `CERT_DIR/mykey.pem') define(`confCLIENT_CERT', `CERT_DIR/mycert.pem') define(`confCLIENT_KEY', `CERT_DIR/mykey.pem') dnl # dnl # GMAIL FORWARDING define(`SMART_HOST',`[smtp.gmail.com]')dnl define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl define(`ESMTP_MAILER_ARGS', `TCP $h 587')dnl define(`confAUTH_OPTIONS', `A p')dnl TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl FEATURE(`authinfo',`hash -o /etc/mail/authinfo.db')dnl
Now rebuild sendmail config and start the service 😀
make -C /etc/mail service sendmail restart
Use the below command to test the local smtp .

Following are some short notes / references for APACHE related configuration in Ubuntu
[I used Ubuntu 12.4 version in this post]
If you want to Disable Browsing on every folder inside /var/www/ then Edit following file
nano /etc/apache2/sites-available/default
& Change the Options
‘Options Indexes FollowSymLinks MultiViews’
to
‘Options FollowSymLinks MultiViews’
(means Remove the Indexes word).
and restart apache2 service by
service apcahe2 restart
Remove the following directive from your required folder.
Indexes
For example, you want to remove directory browsing for /var/www/backup folder.
Edit the below file /etc/apache2/sites-enabled/000-default by using following command
nano /etc/apache2/sites-enabled/000-default
The Default config is below.
Alias /backup /var/www/backup
DirectoryIndex index.html
Options Includes Indexes FollowSymLinks MultiViews
Change it below
Alias /backup /var/www/backup
#DirectoryIndex index.html
Options Includes FollowSymLinks MultiViews
Save & Exit , then Restart APACHE Service by
service apache2 restart
If you want to password protect specific folder in Apache so unauthorized users cannot access it, use the following method. There are other better methods available, You can follow them for best practices. I just achieved it this way,,,
First Create password file
htpasswd -c /etc/apache2/passwd zaibtest
(Replace zaibtest with your required username, It will ask you for password, enter password you like to set for user zaibtest. Also you can save this file anywhere you like)
Now protect your required folder, for example I want to protect /var/www/backup folder, then use the following directives in in /etc/apache2/sites-enabled/000-default
nano /etc/apache2/sites-enabled/000-default
Now in end before </Virtualhost> , add following lines …
AllowOverride All Require all granted
Save & Exit , then Restart APACHE2 Service by
service apache2 restart
Now try to access the folder, it will ask you the password.
After providing valid id password, you can access your folder. (I use it to download backup data from remote location)
YOU SEE THIS ERROR WHEN RESTART APACHE2 SERVICE ….
apache2: Could not reliably determine the server’s fully qualified domain name,
… waiting ..
apache2: Could not reliably determine the server’s fully qualified name
If you see above error while restarting apache2 service, To fix that problem, you need to add and directive in the the httpd.conf file. Open the terminal and type,
nano /etc/apache2/httpd.conf
By default httpd.conf file will be blank. Now, simply add the following line to the file.
ServerName localhost
Save & EXIT.
Now restart the server.
service apache2 restart
Edit file `etc/apache2/mods-available/dir.conf` by
nano /etc/apache2/mods-available/dir.conf
and add your option like
DirectoryIndex admin.php index.html index.cgi index.pl index.php index.xhtml index.htm
service apache2 restart
If you want to access your radius manager admin panel via short name (like alias)
Example: You want to use short path http://10.0.0.1/panel to actually access the http://10.0.0.1/radiusmanager/admin.php
Then edit file /etc/apache2/sites-enabled/000-default
and add lines before /virtualhost directive,
Alias /panel /var/www/radiusmanager DirectoryIndex admin.php Options Includes FollowSymLinks MultiViews AllowOverride None order allow,deny allow from all
Now restart apache by service apache2 restart and try to access the site using /panel alias.
[Modified on 26-DEC-2018]
Edit apache2 default config file
nano /etc/apache2/sites-enabled/000-default.conf
Paste following before </VirtualHost> word (this line is usually the last line in this config file, change the name of download1 & folder according to your local setup
Alias /download1 "/some_local_folder/" #DirectoryIndex index.html Options Includes FollowSymLinks MultiViews Indexes AllowOverride None order allow,deny allow from all Require all granted
& restart apache2 server
service apache2 restart
Edit
nano /etc/apache2/ports.conf
# Change Listen 80 to some other port example 1235
Listen 1235
Save and exit.
Now edit
nano /etc/apache2/sites-enabled/000-default
and change <VirtualHost *:80> to some other port like
save and exit,
restart apache
service apache2 restart
we have folder inside /var/www/html/somefolder , we want to restrict direct file view
create .htaccess file and put
order allow,deny deny from all
To log source user port as well
Edit the apache config file & ADD %{remote}p directive to combined & common section
LogFormat "%h %{remote}p %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %{remote}p %l %u %t \"%r\" %>s %O" common
Now you will see the port as well…

Following is a short guide on how you can create your own SMS panel to send SMS to users about various Events using CLI or GUI method.
For example Payment Reminder, Service Down/Up Alert, and any other message you like to convey to all users.
If you have some prior experience with the Linux/SMS tools, I am sure you will ask why to do so much manual work if you already have open source free tools like smsplay, kannel and many others available , the answer is YES the pre made tools/applications have very nice GUI and and have other functions as well, you simply have to install it by single command and that’s it ready to use, but I always like to build my own solution rather then relying on the pre made applications, This way I can twist and modify the method as per my requirements. & yes its fun to play with the code and you feel much confident, happy and relaxed if you manage to create your own working solution that can fulfill your requirement.
Just FYI, DMASOFTLAB Radius Manager 4.1.x will have the function to send account expiry warning SMS before account expires.

# GSM Mobile / MODEM
(I used TELTONIKA GSM USB Device in this example, Picture is attached below . . .)
# Ubuntu 10.x or any flavor of Linux you like to use.
# GAMMU or GNOKII (you can install gammu by apt-get install gammu )
(A very good guide for GAMMU installation & configuration is available here
http://techspalace.blogspot.com/2012/02/send-sms-using-gammu-command-line-tool.html
http://pierky.wordpress.com/2011/10/28/zabbix-send-sms-using-gammu-smsd/
Connect your GSM modem to your Linux Box via USB,
Make sure it is detected properly by Identifying it using DMESG command
dmesg | grep tty
(You may see following information if device is detected OK, As showed below)
As you can see that the modem have been detected as USB ACM DEVICE ttyACM0
Now run gammu config by
gammu-config
It will ask you that gammu configuration file exists, click YES to continue
Now configuration box will open, Select the PORT and EDIT & type your port name that is detected in the dmesg command.
.
Click on OK , then SAVE and EXIT
Now identify it by using following command.
gammu –identify
(You may see following information if its connected OK , As showed below)
root@zaib-desktop:/sms# gammu –identify
Manufacturer : Teltonika
Model : unknown (TM3 EDGE)
Firmware : 05.41.02
IMEI : 3523870xxxxxxxx
SIM IMSI : 410012xxxxxxx62
Test the configuration by sending SMS to your number using CLI method. Use the below command to send sms to your mobile.
echo “Zaib Test Message” | gammu sendsms TEXT 03333021909
If you don’t see any error message and receive the message to your number, then we are good to GO . . .
========================================================
TIP:
You can also use WAMMUwhich is a nice GUI frontend for GAMMU. Using it you can perform following functions easily.
Using wammu you can read/edit/delete/copy your contacts, to-do, calendar you can read/create/save/send and Backup your sms. Some type of phone supports file sending, display message including pictures and ringtones playback. Support for backup and import in various formats (vCard, vCalendar, iCalendar, gammu own backup,…) . Export messages to mail (IMAP4, maildir and mailbox storages are supported.
To install wammu, simply issue below command from GUI terminal.
apt-get install wammu
After installation completes, Goto Applications / Accessories / >Wammu
Run its configuration wizard to detect the modem and start using it 🙂
========================================================
.
Download following sms-panel-zaib.rar file from following location , and extract all files in a new folder /sms
http://www.mediafire.com/?f77465ogydpe4fp
Following are the contents of /sms (after extracting)
root@zaib-desktop:~# ls /sms
start = > It executes all the scripts in order, First init , then startsms
data => Contains Users Mobile Numbers and Names, Sample Numbers are included. Modify it as per your requirements
path => Contains all the paths for the scripts/dir
init => This script extracts mobile nos and data from various sources and create temporarily dunp files
message => Contains Message that will be sent to users, Modify it as per your requirements
mobile.no = > Automatically created via script which contain mobile nos. only
startsm => This script actually sends sms using gammu
=============================================
Now first edit data file which contains the mobile numbers.
nano /sms/data
Type your user mobile number in the following manner
# User’s Mobile Numbers and there Names
03333021909 # Syed Jahanzaib-Admin No.
03331234567 # A-420, Lake View Cottages :d
03211122334 # X-20, A One Villas Bungalows :p
Now SAVE and EXIT ( By pressing CTRL+O , then ENTER, then CTRL+X )
Edit the message file, it will contain the message that will be delivered to users.
nano /sms/message
Now type your required message. For example:
Dear User,
Due to some scheduled maintenance work, Internet service will not be available from 3:00pm till 5:00pm on 25th December, 2012.Thank you for your co-operation & Sorry for the inconvenience.
Regard’s
AA Networks (Pvt) Ltd. / zaib 🙂
Now SAVE and EXIT ( By pressing CTRL+O , then ENTER, then CTRL+X )
Now type /sms/start to execute the whole process.
It will first execute init script which will extract data from the paths / files,
Then it will start sendsms script which will actually send the sms to all the numbers fetched from init scripts (Users mobile numbers are mentioned in the data file)
To use Customize GUI Panel, through which we can manage users mobile numbers list, and send sms to this list, You have to first install WEBMIN. which is a very nice multi purpose GUI tool to manage various Linux components
If you are using UBUNTU, you can install it via apt-get
First edit sources file, so that apt-get can fetch data from webmin directly.
nano /etc/apt/sources.list
Paste the following lines at end.
deb http://download.webmin.com/download/repository sarge contrib
deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib
Save & Exit.
Now execute following commands to install GPG key with which the repository is signed. Use the below command.
cd /root
wget http://www.webmin.com/jcameron-key.asc
apt-key add jcameron-key.asc
Now you will be able to install with the commands :
apt-get update
apt-get install webmin
after successful install , you can access it using the URL it showed you after successful message.Eample::
https://10.0.0.1:10000
[Use your root ID & Password to Login],
After successful login, you will see following screen . . .
.
Now goto OTHERS / CUSTOM COMMANDS
Click on Create A New File Editor
In Description, Type any EDIT USERS MOBILE NUMBER

Congrats, you have created a file editor which can edit the users mobile numbers,
After SAVING above file editor, you will be redirected back to main menu,
Now we will create a new file editor, which will actually send the message you type in the available box.
.
In Description, Type any Send SMS to ALL
In File to EDIT , tpye the message file name /sms/message
In Command to run after saving, type /sms/start
Click on SAVE
As showed in the image below . . .
.
.
Now you will have the menu something like below.
.
Now Click on the Edit Users Mobile Nos. button
& add the required mobile numbers in following manner.
Click on SAVE to save the entries in /sms/data.
.
Now to send SMS to the list, Click on Send SMS to ALL
Type the message in the box, and click on SAVE, after saving, it will auto execute the /sms/start script which will start sending the message you just typed to the list. It may take long time to send SMS if you have large numbers of List. In my case, it took 3-4 Seconds per SMS.

Yesterday I was trying to upload a 450GB VMDK file to ESXi host. (Actually it was VHD file and I converted it to VMDK using starwind converter), and it was uploading dead slow and showed countless hours to complete the upload. After some googling I found that generally it takes too much time to Upload/Download any VM/ISO File FROM/TO ESXi host. I also tried VEEAM FASTSCP free tool but no avail. It still works very slow.
However if you add FTP service to your ESXi server, and use ftp client to upload/download files, then the upload/download will be much faster. ProFTPD runs good in ESXi 5.x and offers high transfer rate over normal transfers.
As showed in the image below . . .
Upload to ESXi Host using Vsphere Client
Upload to ESXi Host using FTP Client [After adding FTP service in ESXi]
.
.
To add FTP Service, use the following method.
First We have to Enable SSH in ESXi . Connect to your ESXi host,
Goto Configuration
Goto Security Profiles,
Click on Properties
.
SSH service is now enabled on ESXi.
Now Connect to your ESXi host using any ssh client like putty.
Navigate to your datastore folder. For example the datastore on my ESXi host name is 1TB,
cd /vmfs/volumes/1TB/
[Change the 1TB to match your datastore name]
Create any folder where your FTP Service files can be downloaded from the internet or any other source.
[make sure internet service is enabled so file can dierctly download to esxi host, if its not possible then download the package on your client PC, then upload it using Vsphere client and skip to esxcli software install section below . . . ]
mkdir ftp
cd ftp
Now download proftpd by using wget
wget http://esxi-customizer.googlecode.com/files/ProFTPD-1.3.3-8-offline_bundle.zip
Now install it by using esxcli
esxcli software vib install --no-sig-check -d /vmfs/volumes/1TB/ftp/ProFTPD-1.3.3-8-offline_bundle.zip
[Change the 1TB to match your datastore name]
Later if you decide to remove proftp , simply issue following command
To uninstall the package run the following command
esxcli software vib remove -n ProFTPD
Now test it by using simple dos ftp command
ftp 10.0.0.1
Or using any ftp client like CUTEFTP PRO

Its a good idea to virtualize various servers so underutilized hardware can be used more efficiently, as now a days, getting good hardware is not a big deal. It can save considerable amount of power consumption , reduced heat factor , easy to mange multiple VM using various tools like Vcenter / VEEAM (my favorite), VM Explorer , live migrations from one Virtual Server to Another, Backup & Restore becomes very easy and the list goes on . . .
Recently I did an installation of a network where they were low in hardware resources but still they wanted to utilize the benefits of Mikrotik Router OS with external Squid proxy server and also the Radius Billing Server . So in total they required at least 3 physical machines, but I managed to install all of them on single server using Virtualization technology of VMWARE ESXi 5.x (64bit) and it worked so great 🙂
Here is how I did it.
Note: Because of some time shortage, I am just giving you an idea how it can be done, I am not writing in pin point details on how to connect every machine with Virtual/Physical switches. I will write about it soon.
IBM Xseries 3650 XEON Dual Processors with Quad Cores p/p
3.5″ 15krpm SCSI in RAID 10 mode (300GB x 6) (the more Faster drives (like 10-15krpm) you have, the better result you will be able to achieve. Preferably in RAID mode, either 10 or 0, depend on your management and goals, in this example I used 15krpm SCSI HDD’s with dedicated RAID controller. I tested it on IBM xseries with RAID0 and found RAID 0 much more faster with 15krpm but its not redundant, one drive fail and your whole RAID will go down, so if you want redundancy, go with at least RAID 5 or RAID 10 (Recommended) , Raid 1 is also good as it mirrors each drive, but requires additional drives and also for proxy, its useless to use mirroring as it would be requiring more read/write burden on controller, oh GOD, in which argument I got into :p)
16GB RAM (Mikrotik doesn’t requires much RAM in fact it officially supports maximum of 2G, but Radius and Squid do requires some good amount of RAM, I dedicated 8 GB to SQUID, 4GB to Radius, 1 GB to Mikrotik)
4 Network Adapters ( In this article, due-to time shortage, I have only mentioned howto add two network adapters for LAN and WAN link using virtual Switch tech, but you can add more as per your requirements)
1) Vmware ESXi 5.x 64bit as a Virtual Hyper-visor Server
Guest OS installed in this virtual server’s are as following
2) Mikrotik Router-OS 5.22 [1GB Ram +100GB virtual HDD assigned to this VM]
3) Ubuntu 10.4 for SQUID Proxy (2.7) [8GB Ram +500GB virtual HDD assigned to this VM]
4) Ubuntu 10.4 for Radius Manager Billing System [4GB Ram +200GB virtual HDDassigned to this VM]
TIP: You can use the following RAID calculator to evaluate how much space you will be getting various RAID modes.
First install Vmware ESXi. You can get its free edition from http://www.vmware.com , just register and download the latest version , it would be in .iso format, Simply burn it to CD, and install it on your server , its very simple to install the ESXi, nothing more then just clicking NEXT NEXT 🙂
After ESXi installed, configure IP address on it, so you can manage it using its client called Vsphere client.
To shorten the story I am using only two interfaces for the mikrotik, LAN and WAN. in this example (shorten version) ESXi have two interfaces connected , one with the LAN user switch and other interface connected with the WAN (physically)
Goto Configuration tab
From the list appear in Hardware section, click on Networking and click on ADD Networking
As showed in the image below , , ,
Ok, our virtual switch is created.
Now its time to bind our WAN adapter in this switch. (So it can later be used for WAN for all hosts we will requiring for)
Click on the Properties
Done.
Now create new Virtual Machine for your Mikrotik.
Select necessary hardware that you required as required per user load. for example
Mikrotik = 1 CPU / 1 GB RAM / 10 GB HDD /
In Network Adapter Section, by default only one adapter is added, You have to add another adapter by selecting the number of adapters in drop down listing.
As showed in the image below . . .
Once the configuration is completed. Simply install the Mikrotik in newly created hosts you just created in above steps.
After configuration is complete, review once again the host settings,
As showed in the image below . . .
After the installation is done, Connect to mikrotik with WINBOX and look for interfaces
As showed in the image below . . .
.
I will write more on it later.

Errdisable is a feature that automatically disables a port on a Cisco Catalyst switch and is supported on most Catalyst switches running the Cisco IOS software.
The Errdisable error disable feature was designed to inform the administrator when there is a port problem or error. The reasons a catalyst switch can go into Errdisable mode and shutdown a port are many and include:
When a port is in error-disabled state, it is effectively shut down and no traffic is sent or received on that port. The port LED is set to the orange color and, when you issue the show interfaces command, the port status shows as Errdisabled.
To enable err-disabled ports on Cisco 3750 switch series. Follow the below . . .
First make telnet connection with the switch
telnet 10.0.0.1
(change the ip as required,)
Enter Password to continue.
To view Disabled Ports:
show interfaces status err-disabled
e.g:
NOC_SWITCH>show int status err-disabled
Port Name Status Reason Err-disabled Vlans
Gi2/0/10 err-disabled link-flapNOC_SWITCH>
To Enable Port:
enable
config t
int G2/0/10
shut
no shut
exit
Change the interface name to match your. In above example I had two 3750-e models in stack mode. so its showing G2, you may get G1 if you have single switch.
TIP:
Link flap means that the specific port continuously goes up and down. The port is put into the errdisabled state if it flaps more than four-five times in few seconds or if LOOPPBACK is detected. The common cause of link flap is a Layer 1 issue such as a bad cable, duplex mismatch.
We can enable recovery loop-back only too. This is lab environment, so to make recovery faster we will configure recovery timer 30 seconds.
you can enable for all reason using below command-
Use this command to disable port security, NOT RECOMMENDED
no switchport port-security
(< You probably dont need this line, its just to disable pot security feature, I used it to perform various tests)

Manually Assigning a MAC Address For VM
To make sure that the same MAC address is assigned to a given virtual machine every time, even if the virtual machine is moved, you can assign the address manually instead of allowing VMware Workstation to assign it automatically. To assign the same, unique MAC address to any virtual machine manually, use a text editor to remove three lines from the configuration file and add two lines. The configuration file has a .vmx extension at the end of the file name.
To change MAC address of any virtual machine running under VM Workstation, Follow the below . . .
1- Make sure that the target VM is turned off.
2- Browse to folder where your VM is available. For example
F:\VM-WARE-IMAGES\UBUNTU
3- Now open VMX file in NOTEPAD , the name would be something like machine_name.VMX
4- Remove the three lines from the configuration file that begin with:
↓
ethernet0.generatedAddress
ethernet0.addressType
ethernet0.generatedAddressOffset
↓
[Note: Change the ethernet0 to match your’s]
Now Add a new static MAC address line to the configuration file with help of the following entries:
ethernet0.addressType = "static" ethernet0.address = "00:11:22:33:44:55"
↓
5- Now Save the configuration file. & Start the VM
