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.
