You could try something like...

access-list 100 permit icmp host any
access-list 100 deny icmp any any
access-list 100 permit ip any any

int gi0/0
ip access-class 100 in

i have set "ip access-group 100 in" because i do not have any other option under my int gig0/0 .. But after applying all the above lines do not work it still able to ping from other hosts as well.

apply these under the vty lines
for instance

line vty 0-4
access-class 100 in

the number of vty lines are platform dependant. To cover all lines type line vty 0 ?
in this case the last vty line is 807
R2(config)#line vty 0 ?
  <1-807>  Last Line number
