[jira] Created: (ZOOKEEPER-805) four letter words fail with latest
ubuntu nc.openbsd
four letter words fail with latest ubuntu nc.openbsd
----------------------------------------------------
Key: ZOOKEEPER-805
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-805
Project: Zookeeper
Issue Type: Bug
Components: server
Affects Versions: 3.3.1, 3.4.0
Reporter: Patrick Hunt
Priority: Critical
Fix For: 3.3.2, 3.4.0
In both 3.3 branch and trunk "echo stat|nc localhost 2181" fails against the ZK server on Ubuntu Lucid Lynx.
I noticed this after upgrading to lucid lynx - which is now shipping openbsd nc as the default:
OpenBSD netcat (Debian patchlevel 1.89-3ubuntu2)
vs nc traditional
[v1.10-38]
which works fine. Not sure if this is a bug in us or nc.openbsd, but it's currently not working for me. Ugh.

-----------------------------------------
Pat,
You think this should go into 3.3.2?

Patrick Hunt updated ZOOKEEPER-805:
-----------------------------------
Component/s: documentation
Thanks for pointing out that option, I wasn't aware of it. I linked to ZOOKEEPER-737 which we fixed recently. The "old" version of nc had this same behavior, but we fixed it. I'm not sure what's diff about the old/new version of nc that's causing this.
btw, we should updated the "nc" related ZK docs to point out this option. Is this option available in all nc versions? we may need to note that in the docs as well.

Hi Mahadev, I don't think that's necessary given you can fallback to "traditional" nc, or you can use the -q option as suggested by akovi.
On my ubuntu system (lucid/maverick) I have two executables; nc.openbsd and nc.traditional. "nc" links to openbsd version by default.
Honestly I'm not sure why this is no longer working, given that we addressed the "nc closes input first" in ZOOKEEPER-737

---------------------------------------
Hi, I'm new to Zookeeper but stumbled upon this bug too. The solution is to add the -q1 parameter to nc.
The reason is that by default nc closes the connection as soon as the stdin closes. With -q1 you can override this behavior.
Hope this helps.

-----------------------------------------
sure, do you want to add some documentation to zookeeper admin guide to make it clearer on using -q and the issue with openbsd?
