Linux Command - ps

show the current processes in the tree shape
# ps axjf

normal show all the current processes
# ps auxwww
or
# ps aux (seems the same as the above command)

See the difference of 2 kinds of fully ps show
# ps -auxwww | head -1
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.7/FAQ
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
# ps -eLf | head -1
UID PID PPID LWP C NLWP STIME TTY TIME CMD



#To get info about threads:
# ps -eLf
# ps axms

If we use "-f" and "-L" parameter of ps, it will add
NLWP (number of threads)
LWP (thread ID)
to display the thread informations
-f does full-format listing. This option can be combined with many other
UNIX-style options to add additional columns. It also causes the command
arguments to be printed. When used with -L, the NLWP (number of threads) and
LWP (thread ID) columns will be added. See the c option, the format keyword
args, and the format keyword comm.

Linux Service - DHCP

I am not understand dhcp very well. The following is my experience about dhcp.

DHCP packet flow
Client -- send DHCP Discover
Server -- send DHCP Offer
Client -- send DHCP Request
Server -- send DHCP ACK

These four packets all contain the same Transaction ID
DHCP protocols use option to carry the main messages. These options include message type, server identifier, IP address lease time, renewal time value and rebinding time value etc..

# if you want dhcpd to listen only on the specific interface, add the interface parameter in the dhcpd config file, as following steps
a. update /etc/sysconfig/dhcpd, add " eth1" as the listening interface
DHCPDARGS=" eth1"

b. restart the dhcpd
# service dhcpd restart

c. verify that dhcpd is launched with the " eth1" as the parameter
# ps auxwww | grep dhcpd
root 3848 0.0 0.1 6208 1212 ? Ss 14:51 0:00 /usr/sbin/dhcpd eth1



### Setup the dhcp config
And we config the /etc/dhcpd.conf to include the following options to comply the AutoIP testing item requirement of DLNA Test Plan.

# --- default gateway
# option routers 192.168.0.1;  << comment out the default router of DHCP advertisement to avoid the client receiver to set the default router in the LAN network
option subnet-mask 255.255.255.0;

option nis-domain "domain.org";
option domain-name "domain.org";
option domain-name-servers 192.168.1.1;

option time-offset -18000; # Eastern Standard Time
range dynamic-bootp 192.168.0.10 192.168.0.100;
default-lease-time 300; << Set lease time as 300 seconds to conform the certification testing requirement
max-lease-time 43200;

Besides, we need to setup the server address of binding network interface in the same network domain as the assigned dhcp address. In our example, we set the server network address as 192.168.0.1 and netmask as 255.255.255.0.

### Start up the DHCP Server
Start the DHCP server
# service dhcpd start
Starting dhcpd: [ OK ]

Show the DHCP server current status
# service dhcpd status
dhcpd (pid 11185) is running...

# netstat -anp | grep 67 | grep dhcpd
udp 0 0 0.0.0.0:67 0.0.0.0:* 11185/dhcpd

Stop the DHCP server
# service dhcpd stop
Shutting down dhcpd: [ OK ]

Use netstat to show the current binding port of each daemon

If we want to know which port is binding on which program, we can use the netstat. Use the -p parameter to show the binding program name.
# netstat -anp | more

Use the adapted "make options" to compile shared/static libpcap library

The method of how to compile and install libpcap as static/shared library

Following the command sequence
# make all
# make install
>>　It will produce libpcap.a static library
# make shared
# make install-shared
It will produce the libpcap.so.0.9.7 shared library


How to compile and install openssl as a shared library
# use the following command to produce the Makefile
./config --prefix=/usr shared

# make
# make build-shared
# make install

The message output by the command "make install"
installing libcrypto.a
installing libssl.a
installing libcrypto.so.0.9.8

之後就會在目錄中產出libcrypto.so.0.9.8, libssl.so.0.9.8兩個shared library
(These two libraries are the mainly components of the openssl package)
