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?

  1. myhost and remotehost are on different networks.

  2. The ipf kernel module is not loaded.

  3. remotehost does not have a route to myhost.

  4. Telnet is an insecure protocol and therefore Solaris IP Filter always blocks it.

  5. myhost has a block out rule for traffic to remotehost.

Answer: E

Question No: 29 – (Topic 1)

The system administrator of a firewall running Solaris IP Filter writes an updated set of rules in /root/newrules. Before implementing the rules, the rule set needs to be tested for syntax errors. Which command accomplishes this?

  2. All NTP clients on the local subnet must be configured to support key negotiation.

  3. The server is authoritative for a reference clock.

  4. All NTP servers on the local subnet must be configured to support key negotiation.
