Hi, first time using the sandbox 2.6.4 ( I am extremely new to docker, but more familiar with vmware ) Recently, I tried to learn/test a backup product. Environment: =========== But before that, I notice the difference of ssh -p 2222 vs standard ssh e.g. ssh -p 2222 ========== [root@sandbox-hdp network-scripts]# ifconfig -a eth0 Link encap:Ethernet HWaddr 02:42:AC:11:00:02 inet addr:172.17.0.2 Bcast:172.17.255.255 Mask:255.255.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1650387 errors:0 dropped:0 overruns:0 frame:0 TX packets:1557340 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:955319881 (911.0 MiB) TX bytes:726520084 (692.8 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:35792271 errors:0 dropped:0 overruns:0 frame:0 TX packets:35792271 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1 RX bytes:23574288126 (21.9 GiB) TX bytes:23574288126 (21.9 GiB) standard ssh =========== [root@sandbox-host network-scripts]# ifconfig -a docker0 Link encap:Ethernet HWaddr 02:42:8A:0F:5C:DD inet addr:172.17.0.1 Bcast:172.17.255.255 Mask:255.255.0.0 inet6 addr: fe80::42:8aff:fe0f:5cdd/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1557361 errors:0 dropped:0 overruns:0 frame:0 TX packets:1650404 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:704727380 (672.0 MiB) TX bytes:955327389 (911.0 MiB) ens32 Link encap:Ethernet HWaddr 00:0C:29:8C:91:1D inet addr:128.222.110.164 Bcast:128.222.110.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe8c:911d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1289914 errors:0 dropped:0 overruns:0 frame:0 TX packets:572090 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 406562254 (387.7 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:383 errors:0 dropped:0 overruns:0 frame:0 TX packets:383 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1 RX bytes:37548 (36.6 KiB) TX bytes:37548 (36.6 KiB) vethda55ac8 Link encap:Ethernet HWaddr EA:46:30:49:97:B3 inet6 addr: fe80::e846:30ff:fe49:97b3/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1557361 errors:0 dropped:0 overruns:0 frame:0 TX packets:1650412 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:726530434 (692.8 MiB) TX bytes:955328037 (911.0 MiB) Symptom ======== After I installed a service called HDBoost service. I was able to telnet to service port 18043 using ip 172.17.0.2 [root@sandbox-hdp ~]# telnet 172.17.0.2 18043 Trying 172.17.0.2... Connected to 172.17.0.2. Escape character is '^]'. But when telnet to 128.222.110.164 I am not able to make a connection. I cannot keep using 172.17.0.2 because I need to access it remotely from my work pc desktop which uses 128.222.110.0 subnet. Please kindly help if you know an answer or work around. ... View more

I realized one thing.

Also using root user to do tail -F ambari-server.log is a pain due to long path names. Is it suppose to be like this ? ... View more
