Summary: Discusses Terminal for diagnosing network LAN Zoo issues on Mac

Need Windows? Go here.

Terminal runs on a Rhino for Mac workstation. It provides command line access to several useful network diagnostics to troubleshoot connectivity issues between Rhino for Mac workstations and Zoo servers.

The Network Utility provides these useful network tests:

1. ping: The ping diagnostics utility is the primary TCP/IP tool used to troubleshoot connectivity, reachability, and name resolution. Ping verifies IP-level connectivity to another TCP/IP computer by sending Internet Control Message Protocol (ICMP) Echo Request messages. Receipts of corresponding Echo Reply messages are displayed, along with round-trip times.

ping zoo.mcneel.com

Successful ping response looks like:

> ping zoo.mcneel.com
PING zoo.mcneel.com (192.168.0.100): 56 data bytes
64 bytes from 10.22.0.15: icmp_seq=0 ttl=127 time=9.981 ms
64 bytes from 10.22.0.15: icmp_seq=1 ttl=127 time=8.630 ms
64 bytes from 10.22.0.15: icmp_seq=2 ttl=127 time=9.774 ms

Failed ping response looks like:

> ping zoo.mcneel.com
PING zoo.mcneel.com (192.168.0.100): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3

Press Ctrl+C to cancel the ping command.

2. nslookup: The DNS Lookup diagnostic utility displays information that you can use to diagnose Domain Name System (DNS) infrastructure.

nslookup zoo.mcneel.com

Successful nslookup response looks like:

> nslookup zoo.mcneel.com
Server:		192.168.0.1
Address:	192.168.0.1#53

Non-authoritative answer:
Name:	zoo.mcneel.com
Address: 192.168.0.100

Failed nslookup response looks like:

> nslookup zoo.mcneel.com
** server can't find zoo.mcneel.com: NXDOMAIN

3. Traceroute: The Trace Route diagnostic utility determines the route taken to a destination by sending Internet Control Message Protocol (ICMP) echo packets with varying IP Time-To-Live (TTL) values to the destination. Each router along the path is required to decrement the TTL on a packet by at least 1 before forwarding it, so the TTL is effectively a hop count. When the TTL on a packet reaches 0, the router should send an ICMP Time Exceeded message back to the source computer.

traceroute zoo.mcneel.com

Successful traceroute response looks like:

> traceroute zoo.mcneel.com
traceroute to zoo.mcneel.com (192.168.0.100), 64 hops max, 52 byte packets
 1  192.168.0.100 (192.168.0.100)  9.391 ms  6.558 ms  8.538 ms

Failed traceroute response looks like:

> traceroute zoo.mcneel.com
traceroute to zoo.mcneel.com (192.168.0.100), 64 hops max, 52 byte packets

4. Port Scan (nc): The Port Scan test scans for open TCP ports. In the case of the Zoo, you will want to scan for TCP Port 80.

nc -z -v zoo.mcneel.com 80

Successful netcat response:

> nc -z -v zoo.mcneel.com 80
Connection to zoo.mcneel.com port 80 [tcp/http] succeeded!

Failed netcat response:

netcat will not return. To cancel, press Ctrl+C

If this test fails, then make sure the Zoo server service is running. You can do this by using either ZooAdmin.exe or the Services applet in Control Panel. Also, make sure TCP Port 80 is open on any firewall software, for both incoming and outgoing traffic, running on the Zoo system.
