Many thanks to those who replied, specially to David L S.
Now I can run amanda client on a solaris 10. Here is a 
short list of things I had to do to make it work (I hope 
it helps others too):

- modify the file /etc/service to add the following line:
        amanda          10080/udp

- create a file (for example: place it in /tmp/amanda) with the 
  entry you had in your inetd.conf:
        amanda  dgram  udp  wait  your_amanda_user_name full_path_to_amandad  
amandad

- conver inetd.conf(4) entry to service of solaris 10, by running inetconv:
        inetconv -f -i /tmp/amanda 

- check if the service is online:
        svcs -v | grep amanda

        (output should be)

        online   -    15:27:33  - svc:/network/amanda/udp:default

- If it's not online or other problems, you can use svcadm to
  restart (enable or refresh) the service. For example:

        svcadm -v [enable|restart|refresh] /network/amanda/udp:default
        
- make sure amandad is listening:
        netstat -a | grep amanda

        (output should be like)

         *.amanda            Idle


Good luck,
-AM
