To build Linphone for iPhone and iPad

Step 1: Install XCode

Install XCode

Step 2: Install required linux package through MacPort

Install MacPort, then install these ports: automake, autoconf, libtool, intltool, wget, pkgconfig, gtk2

For bash

$ sudo port install coreutils automake autoconf libtool intltool wget pkgconfig cmake gmake yasm grep doxygen ImageMagick optipng gtk2

$ wget –no-check-certificate https://raw.github.com/yuvi/gas-preprocessor/master/gas-preprocessor.pl

$ sudo mv gas-preprocessor.pl /opt/local/bin/.

$ sudo chmod +x /opt/local/bin/gas-preprocessor.pl

Note, on my Mountain Lion OS, I can’t get “sudo” to work, so I enable the root via this link: http://support.apple.com/kb/PH11331

and use the following commands

$ su

$ port install coreutils automake autoconf libtool intltool wget pkgconfig cmake gmake yasm $ grep doxygen ImageMagick optipng gtk2

$ wget –no-check-certificate https://raw.github.com/yuvi/gas-preprocessor/master/gas-preprocessor.pl

$ mv gas-preprocessor.pl /opt/local/bin/.

$ chmod +x /opt/local/bin/gas-preprocessor.pl

Step 3: Install or Update Git

Install git. I followed the instruction on this great github article.

To update an existing git install (if you got an git version error in the later steps)

$ git clone git://github.com/gitster/git.git

Step 4: Obtain linphone source code

Download linphone source from this git tree page

$ git clone git://git.linphone.org/linphone-iphone.git --recursive

Step 5: Follow the README file in linkphone-iphone directory

Follow the README in linphone-iphone directory

Link important libtoolize to glibtoolize

$ sudo ln -s /opt/local/bin/glibtoolize /opt/local/bin/libtoolize

Update SDK_VERSION in submodules/build/iphone-config.site if appropriate

Generate the liblinphone dual arch sdk:

$ cd submodules/build

$ make -f builder-iphone-simulator.mk all && make -f builder-iphone-os.mk all &&make -f builder-iphone-os.mk delivery-sdk

Link host’s strings

For Xcode prior to 4.3:

$ sudo ln -s  /usr/bin/strings /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/strings

For newer XCode:

$ sudo ln -s  /usr/bin/strings /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/strings

Build SDK

$ cd submodules/build

$ make veryclean

$ make all

7. After step 5 is completed, open linphone.xcodeproj in linphone-iphone directory. Just build as normal.

Troubleshooting

On Snow Leopard with MacPort 1.9.2, I had to copy /usr/X11/share/aclocal/pkg.m4 to /usr/share/aclocal to get rid of the PKG_CHECK_MODULES error. Thanks to Thomas Covo’s response to a thread. After doing so, run ./autogen.sh in all external plugins (exosip, osip, speedx) and

cd submodules/externals/exosip

./autogen.sh

cd ../osip

./autogen.sh

cd ../speex

./autogen.sh

cd ../../linphone

./autogen.sh

To add a new jdk, I downloaded the jdk-6u-linux-i586.bin from the Oracle Java site. Unzip it

chmod 755 jdk-6u27-linux-i586.bin

./jdk-6u27-linux-i586.bin

It unzip it to a directory jdk1.6.0_27. I moved it to /usr/lib/jvm,

mv jdk1.6.0_27 /usr/lib/jvm

Then install the jdk1.6.0_27 as a Java alternative. The number 3 is for the priority.

update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_27/bin/java 3

Now if you do “update-alternatives –config java” again, you would see jdk1.6.0_27 got added as a new alternative. Type 3 and hit Enter to select.

Step 2: Download Windows Automation Snapin for PowerShell at http://wasp.codeplex.com/ And Unzip WASP.zip to a Directory

Step 3: Change PowerShell Execution Policy
Go to Start->”Programs”->”Accessories”->”Windows PowerShell” Or just type “powershell” at the Run prompt.

Get the current execution policy:

To be able to run all scripts, including the unsigned ones (take your own risk!), change the PowerShellexecution policy from the default “Restricted” to “Unrestricted”.
To check the current execution policy, type

get-executionpolicy

at the PowerShell prompt.

To change the execution policy to “Unrestricted”, type

set-executionpolicy Unrestricted

Then do get-executionpolicy again to check that the policy has been changed

    [ tableView reloadData];
}

Step 1: Installation

Obtain installation (binary) package from Net-SNMP site and install using all default setting. By default, the Net-SNMP is installed under C:/usr. Follow the list of snapshots below to download and install the latest stable version of Net-SNMP.

Step 2: Configuration

Add Net-SNMP to the path. Go to “Control Panel”->”Performance and Maintenance”->”System”. Click “Advanced” Tab. Then click “Environment Variables”. From System Variables list, select Path, then click “Edit” button. Append “C:net-snmpbin” to Path variable value. Then click “OK”->”OK”->”OK” to save.

Select “Start”->”Run” to open a DOS prompt. Then at the prompt, type “snmpconf –i”. Then select C:/net-snmp/etc/snmp/snmp.conf to read the default setting in.

Select snmpd.conf, which is configuration file for the Net-SNMP SNMP agent. It’s documented on this SNMPD.CONF page. The snmp.conf file the configuration file for the Net-SNMP applications and it’s documented on this SNMP.CONF page.

The most basic configuration is to set up read and write communities and community strings. To do so, select 1 for “Access Control Setup”.

Select “3: a SNMPv1/SNMPv2c read-only access community name“. Hit Return key.

Enter “public” as the community string; you can enter any string you like. The community string works a bit like password. Then enter nothing for both “the hostname or network address to accept…” and for “The OID that this community ….”. By entering nothing, we specify that we will accept SNMP queries from all hostnames and all network addresses and that this community can view all MIBs installed on this SNMP agent.

Select “4: a SNMPv1/SNMPv2c read-write access community name“. Hit Return key.

Enter “public” as the community string. Then enter nothing for both “the hostname or network address to accept…” and for “The OID that this community ….”. By entering nothing, we specify that we will accept SNMP read-write queries for this community from all hostnames and all network addresses and that this community can view all MIBs installed on this SNMP agent.

To exit and save snmpd.conf, enter “finished” -> “finished” -> “quit”.

To verify the Net-SNMP has been configured correctly, go to C:net-snmpbin and double click “snmpd.exe” to run the SNMP agent.

You may see this warning message because SNMPD would try to bind to several TCP ports (161 for general SNMP messages and 162 for trap messages), just click “Unblock”. If you are not the admin of your machine, you might want to ask your admin whether you can run a SNMP agent on your machine.

You should see a terminal that looks like this. This is the log windows of snmpd.exe. Only close it if you want to kill snmpd.exe.

Now you are ready to poll network info from your SNMP-enabled box! At the prompt, type “snmpwalk –v 2c –c public localhost”. The “snmpwalk” command retrieves a subtree of management values using SNMP GETNEXT requests. It’s syntax is as followed:

snmpwalk [APPLICATION OPTIONS] [COMMON OPTIONS] [OID]

If no argument is given, snmpwalk will search the subtree rooted at SNMPv2-SMI::mib-2. The “-v 2c” option tells snmpwalk to use SNMP version 2c, whereas the “-c public” option specifies the public community string. Lastly, “localhost” option tells snmpwalk to query from localhost.

C:\usr\etc\snmp> snmpwalk -v 2c -c public localhost

To set up SNMPv3 security, here is a short instruction, thanks to this article on netadmintools.com. First, add the following two lines to snmpd.conf

createUser jess MD5 "jess_password" DES
rouser jess

Make sure you restart the Net-SNMP Agent service after these changes. This will set up a read only user jess that will authenticate with the passphrase jess_password using MD5/DES for encryption. Note that the password is available in plain text in the file, unlike with the GNU/Linux configuration; however, the traffic is still encrypted.

Now we can get the sysUpTime, how long snmpd has been running.

C:\usr\etc\snmp> snmpget -v 3 -u jess -l authNoPriv -a MD5 -A jess_password localhost sysUpTime.0 

1. Select “Start”->“Settings”->”Control Panel”

1. Double click “Add Hardware”

1. Click “Next” and select “Yes, I have already connected to the hardware”.

1. Select “Add a new hardware device” and click “Next”.�

1. Click “Install the hardware that I manually select from a list(Advanced)” and then “Next”.

1. Follow the following screenshots to finish installing the loopback device

1. Follow the following screenshots to configure the loopback device.� I give the device an IP of 192.168.100.2, with network mask of 255.255.255.0, and gateway of 192.168.100.1.

Assign IP address, subnet mask, and default gateway.

Run “ipconfig /all” to get the mac ID assigned to this loopback device . Windows assign 02-00-4C-4F-4F-50 for my MAC ID.

Add the ARP entry for this loopback device, using the MAC ID from last step.

Testing this device by pinging it.

1. Now you should be able to see this device and monitor traffic through this device from Wireshark.

Remove the Loopback Device

Troubleshooting

Problem 1: WIreshark could not detect the loopback device

Solution: If you don’t see the loopback device after clicking the “List the available capture interfaces” button. Try restart your machine.

When it works, Wireshark should detect the loopback device and display it in its Capture Interfaces list.

Problem 2: The loopback interface does show in the Capture Interface list but there is no packets captured!!

Solution:

1. Check the ARP table

Make sure there is an entry for the loopback device in the ARP table. To check, type “arp –a” at the command prompt.

�

If there is no entry for the loopback device, add it as followed:

1. Check the routing table

Make sure the packets for 192.168.100.2 is routed corrected to the loopback interface (with 192.168.100.2 IP address). A common mistake is that there is a route of higher priority to the real loopback interface(127.0.0.1).

To add a static route for packets for 192.168.100.2 to the loopback device, do as followed:
