No information on open ( Fake) ports

[skynetonsecurity () gmail com]

Hi all,

While conducting pentest I found nmap giving some open ports with -sS scan & -sV scan giving status open|filtered. But 
when I tried to telnet the ports for banner, I was not able gather any information timeout happened.

I think this is because of IPtables with tarpit or kernal hardning?

what could be the other reasons for this?

scan result as follows for -sS:

22/tcp    open     
23/tcp    open     
25/tcp    open  
42/tcp    open     
53/tcp    open     
57/tcp    open     
68/tcp    open     
80/tcp    open     
88/tcp    open     
98/tcp    open     
110/tcp   open     
111/tcp   open     
135/tcp   filtered 
137/tcp   filtered 
138/tcp   filtered 
139/tcp   filtered 
143/tcp   open     
389/tcp   open     
443/tcp   open     
445/tcp   filtered 
464/tcp   open     
522/tcp   open     
563/tcp   open     
593/tcp   filtered 
636/tcp   open     
999/tcp   open     
1023/tcp  filtered 

& for -Sv
