You configure Solaris IP Filter on a Solaris system named myhost as a host-based firewall. While
attempting to telnet to myhost from another host named remotehost, you receive this error:
$ telnet myhost
Trying 192.168.1.100…
telnet: Unable to connect to remote host: Connection timed out
You run netstat -a on myhost and find this entry:
Local Address Remote Address Swind Send-Q Rwind Recv-Q State
————– ————————— ——— ———– ———- ———– ————
myhost.23 remotehost.39846 0 0 49640 0 SYN_RCVD
What is the cause of this problem?
A.
myhost and remotehost are on different networks.
B.
The ipf kernel module is not loaded.
C.
remotehost does not have a route to myhost.
D.
Telnet is an insecure protocol and therefore Solaris IP Filter always blocks it.
E.
myhost has a block out rule for traffic to remotehost.
