Networking problems

[jhjadmin]

Hi,

I have configured a static ip address and am now running in some weird behaviour. There are some servers on the same subnet, which I am not able to reach from the truenas system and vice versa. I can reach the weblogin and all from my client machine (same subnet).

Example of a server which can be reached:

Code:

root@sto-00-02[~]# traceroute 172.16.1.4 -n
traceroute to 172.16.1.4 (172.16.1.4), 30 hops max, 60 byte packets
 1  172.16.1.4  0.629 ms  0.601 ms  0.563 ms

Another example of a server which can not be reached:

Code:

root@sto-00-02[~]# traceroute 172.16.1.22 -n
traceroute to 172.16.1.22 (172.16.1.22), 30 hops max, 60 byte packets
 1  * * *
 2  * * *
 3  * * *
</snip>

The second server has no firewall rules or anything like that. It is reachable by my client machine and all other servers in my environment.

Network interface:

Code:

root@sto-00-02[~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp0s25: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:19:99:6b:b7:0b brd ff:ff:ff:ff:ff:ff
    inet 172.16.0.202/22 brd 172.16.3.255 scope global enp0s25
       valid_lft forever preferred_lft forever
    inet6 fe80::219:99ff:fe6b:b70b/64 scope link
       valid_lft forever preferred_lft forever

Routing table:

Code:

root@sto-00-02[~]# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         172.16.0.1      0.0.0.0         UG    0      0        0 enp0s25
172.16.0.0      0.0.0.0         255.255.252.0   U     0      0        0 enp0s25

What I am as well wondering is the <dict> entry from the truenas CLI namespace. Doesn't it imply that there is more than one address or is it the standard display because of the link local address?

Code:

[sto-00-02] network general> summary
+----------------+------------+
|            ips | <dict>     |
| default_routes | 172.16.0.1 |
|    nameservers | 172.16.1.1 |
|                | 172.16.1.4 |
+----------------+------------+

But interface_in_use is fine:

Code:

[sto-00-02] network> interface ip_in_use
+------+--------------+---------+--------------+
| type | address      | netmask | broadcast    |
+------+--------------+---------+--------------+
| INET | 172.16.0.202 | 22      | 172.16.3.255 |
+------+--------------+---------+--------------+

Problem was an error on the switch. It had nothing to do with any configuration issues on the appliance itself.
