----
2018-12-20 16:01:17 UTC - Sijie Guo: I think it is easier to first try if you can telnet to any broker first:

`telnet &lt;broker-ip&gt; 6650`.
----
2018-12-20 16:27:45 UTC - Sijie Guo: @Irfan: have you downloaded the offloader distributions and untared it to `offloaders` directory in your pulsar home directory?
----
2018-12-20 16:51:53 UTC - Irfan: @Sijie Guo No I haven't. Where can I download these distributions? I can't seem to find any documentation referring to them
----
2018-12-20 17:18:03 UTC - Yuvaraj Loganathan: Thanks @Sijie Guo 
----
2018-12-20 18:04:25 UTC - Irfan: @Sijie Guo Nevermind I figured it out. Thanks for your help! Is there any documentation on the pulsar website about this? There seems to be nothing about it on the tiered storage section. I think it would be very helpful to add.
----
2018-12-20 19:45:45 UTC - Matteo Merli: @Yuvaraj Loganathan Just sent out 2nd RC <https://lists.apache.org/thread.html/b860a4c0f8c55cf8cd0472ee677ba3349670b81cf1609362b829fb18@%3Cdev.pulsar.apache.org%3E>

----
2018-12-20 20:07:28 UTC - Grant Wu: The CLI tool
----
2018-12-20 20:09:38 UTC - Grant Wu: I only see this code path :confused: <https://github.com/apache/pulsar/blob/master/pulsar-client-tools/src/main/java/org/apache/pulsar/client/cli/CmdConsume.java#L125>
----
2018-12-20 20:43:58 UTC - Sanjeev Kulkarni: Currently I don’t think so. But something that can be added fairly simply by adding another option for regex style or comma seperated topic names
----
2018-12-20 23:04:15 UTC - Sijie Guo: I can’t find the docs either. It seems to be missing at the website. I have created an issue to work on it.
----
2018-12-21 06:53:13 UTC - Roger Yates: Thanks for the suggestion, @Sijie Guo, if I have Proxifier redirecting to the Corporate proxy, he connection succeeds, but when I deactivate Proxifier, then connection is refused from telnet too. It seems to be that Pulsar uses Netty for its IO, and this ignores the Java proxy settings. One of my colleagues will likely investigate options for configuring Netty handlers to do the redirect, while I am on leave.
