Sharing folders between VMware host and guest O.S.

1. Install VMware Tools. See http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1022048 and http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1022525
     . Virtual Machine -> Install VMware Tools
           sudo mkdir /mnt/vmtools
           sudo mount /dev/sr0 /mnt/vmtools
           cd /mnt/vmtools
           tar zxvf VMwareTools-x.x.x.tar.gz -C /tmp
           cd /tmp/vmware-tools-distrib
           sudo ./vmware-install.pl -d
           sudo reboot

2. Configure share folder
     . Go to settings of the guest VM -> Sharing
           Setup the sharing folder

3. The location of the shared folder will be in /mnt/hgfs or /media/psf/

2. Open terminal and enter "rvictl -s deviceUUID" to start device with interface rvi0
3. Run wireshark and start capturing the packet on interface rvi0
4. Sotp interface rvi0 by enter "rvictl -x deviceUUID"

PS. deviceUUID is the UUID of your iOS device

No interface available in Wireshark on Mac OS

Change the permission to 644 on the BFF (Berkeley Packet Filter) in /dev/

sudo chmod 644 /dev/bpf*

or

whoami to find out your name

sudo chown yourname:admin /dev/bp*

And restart wireshark!

USB to Serial (Console) on Mac OS X

Use the built-in "screen"

1. Install the USB to Serial driver (PL2303 Mac OS X)

2. In terminal, launch Screen and connect to device by following command (115200: baud rate)

    screen /dev/cu.usbserial 115200
or screen /dev/tty.usbserial 115200

To list the screen sessions: screen -ls   (output in format pid.tty.host)

To resume a detached session: screen -r   or  screen -x pid

Commands in 'screen':

'Control+a' and then '?' : Help

'Control+a' and then 'H' : toggle logging

'Control+a' and then 'Control+\' : Quit screen

tcpdump wirte to screen and file

Basic form:
tcpdump -i interface OPTIONS -w - | tee outputFile | tcpdump -r -

-w - : write data to stdout
tee : write data to file and its own stdout
-r - : read data from stdin

Example:
tcpdump -i enp3s0 udp and port 53 -w - | tee packet.pcap | tcpdump -nn -r -

Use iptables for CentOS 7 instead of firewalld

CentOS 7 is now using firewalld instead of iptables. To use iptables, here are the steps:

1. Disable firewalld
systemctrl disable firewalld

2. Stop firewalld
systemctrl stop firewalld

3. Install iptables-services
yum install iptables-services

4. Enable iptables
systemctl enable iptables

5. Start iptables
systemctl start iptables

 6. Configure iptables as usual (/etc/sysconfig/iptables)

Add a private key to Mac OS X KeyChain

ssh-add -K ~/.ssh/id_rsa

ps. make sure the permission of id_rsa is 600

Completely remove nf_conntrack from kernel

1. Remove the following line, if it exists, in /etc/sysconfig/iptables-config
   IPTABLES_MODULES="ip_conntrack_netbios_ns"

2. Stop iptables
   iptables -F

3. Remove the related modules
   modprobe -r xt_NOTRACK nf_conntrack_netbios_ns nf_conntrack_ipv4 xt_state
   modprobe -r iptable_nat ipt_MASQUERADE nf_nat nf_defrag_ipv4
   modprobe -r nf_conntrack

Solution for VPN client not working after upgraded to Mac 10.10 Yosemite

Source: http://apple.stackexchange.com/questions/151345/vpn-client-is-not-working-after-yosemite-update-enforce-firewall-policy-fail

Solution: put computer into kext developer mode (-> 10.9 behavior)
   sudo nvram boot-args="kext-dev-mode=1"

To change back to 10.10 behavior (VPN client will not work)
   sudo nvram -d boot-args


After the change, you need to reboot the computer

rpath

Reference: http://ftp.gnu.org/pub/old-gnu/Manuals/ld-2.9.1/html_node/ld_3.html

Add directory to the runtime library search path, for shared object.

Example: Add runtime search path /tmp/igetui

gcc -Wl,-rpath,/tmp/igetui/ $(PLATFORM) $(DEBUG) -lpthread -ldl


OR add it to LD_LIBRARY_PATH
ex.
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/tmp/igetui

OR add it /etc/ld.so.conf and run ldconfig
