Multicast address config lost
On Solaris OS, We use the following command to config the multicast address for NIC in order to process the multicast packets:
# route add 228.228.228.228 10.101.10.2
Where " 228.228.228.228 " is the multicast for specified NIC ip 10.101.10.2 .
Also use the netstat -nr, the above set could been displayed as the following:
Code:
Routing Table: IPv4
  Destination           Gateway           Flags  Ref     Use     Interface 
-------------------- -------------------- ----- ----- ---------- --------- 
228.228.228.228             10.101.10.2          U         1       1020 e1000g0

In our program, we use the function:
setsockopt(sockfd,IPPROTO_IP,IP_ADD_MEMBERSHIP,&mreq,sizeof(mreq)) to
join the multicast group and receive the packets.
At the begining, all runs ok. But after about two days later, the multicast address 228.228.228.228 was lost, which cause our program run unnormmally.
What confuse us is that the above phenomena do not exist on the other UNIX/Linux OS. anyone can fix it,thanks.

zoomer

ZOOMER(1)						      General Commands Manual							 ZOOMER(1)

NAME

       zoomer -- generate a video from a picture by zooming from one point to another

SYNOPSIS

       zoomer options...

DESCRIPTION

       zoomer	automatically  generates a video from a picture. It starts at the full picture and then zooms into the first point. Then zooms out
       and into the next point, etc. At the moment of reaching a point, zoomer will write a text (e.g.	a name).

       zoomer needs a picture (bigger is better) and a data file to define the points to be zoomed into.

OPTIONS

		 --data
		 the data file setting the details to be zoomed.

		 --debug
		 show a verbose output

		 --frames-moveing
		 how many frames between details

		 --frames-stoped
		 how many frames focused on the detail

		 --font-size
		 the size of the text

		 --output
		 the name of the output video

		 --pic
		 the name of the input picture (bigger is better)

		 --replace-output
		 will automaticaly delete a file with the same output name

		 --use-zenity
		 will show a nice graphical progress bar

		 --video-size
		 the video resolution in the WxH notation like 480x360

THE DATA FILE

       The data file is a simple text file to provide informaton about where zoomer must zoom. There must be one  line	by  detail  and  no  other
       information. The zoomer don't supports empty lines or commentaries.

       The detail line has the pattern: X,Y Width Text

       See a data example:

       364,178 57 Bart
       233,246 62 Lisa
       396,274 52 Maggie
       302,059 61 Marge
       228,130 66 Homer

       The Width is the with of the soom square. The Height will be ever proporcional to the output setted height.
