network protocols - TCP DF packets get block though in IPTABLES the required port is allowed by rule -

-

the rule added accept on port 10000 as:

iptables -i input 5 -i eth0 -p tcp --dport 10000 -j accept

but packet 10000 port blocked ipatables log:

packet-droppedin=eth0 out= mac=<00:00:00:00:aa:59:00:90:30:00:00:00:00:00> src=10.78.34.175 dst=10.78.34.171 len=60 tos=0x00 prec=0x00 ttl=64 id=58229 df proto=tcp spt=50694 dpt=10000 window=5840 res=0x00 syn urgp=0

any idea?

please dont close question irrelevant programming.

check port 10000 listening on server:

netstat -an |grep "10000"

then check src ip in server firewall as:

iptables -nl |grep yourip

if have installed other firewall check in too.
