It&#39;s a release note because I believe the user needs to be aware that this would cause bad things to happen if done improperly. Until we either update the documentation or prevent the user from doing this, I think it&#39;s non-obvious and therefore requires a release note. can we close this as won&#39;t fix ? already done apparently<br/> <br/> # wget -O- -d --user=Administrator --password=asdasd --post-data=&quot;otpNode=n_0@10.17.20.233&quot; <a href="http://lh:9000/controller/ejectNode">http://lh:9000/controller/ejectNode</a><br/> Setting --user (user) to Administrator<br/> Setting --password (password) to asdasd<br/> Setting --post-data (postdata) to otpNode=n_0@10.17.20.233<br/> DEBUG output created by Wget 1.14 on linux-gnu.<br/> <br/> URI encoding = ‘UTF-8’<br/> --2012-08-21 17:19:01-- <a href="http://lh:9000/controller/ejectNode">http://lh:9000/controller/ejectNode</a><br/> Host ‘lh’ has not issued a general basic challenge.<br/> Resolving lh (lh)... 127.0.0.1<br/> Caching lh =&gt; 127.0.0.1<br/> Connecting to lh (lh)|127.0.0.1|:9000... connected.<br/> Created socket 3.<br/> Releasing 0x09cb2f48 (new refcount 1).<br/> <br/> ---request begin---<br/> POST /controller/ejectNode HTTP/1.1<br/> User-Agent: Wget/1.14 (linux-gnu)<br/> Accept: */*<br/> Host: lh:9000<br/> Connection: Keep-Alive<br/> Content-Type: application/x-www-form-urlencoded<br/> Content-Length: 24<br/> <br/> ---request end---<br/> [POST data: otpNode=n_0@10.17.20.233]<br/> HTTP request sent, awaiting response... <br/> ---response begin---<br/> HTTP/1.1 401 Unauthorized<br/> WWW-Authenticate: Basic realm=&quot;Couchbase Server Admin / REST&quot;<br/> Server: Couchbase Server 2.0.0r_231_gdcd71d5<br/> Pragma: no-cache<br/> Date: Wed, 22 Aug 2012 00:19:01 GMT<br/> Content-Length: 0<br/> Cache-Control: no-cache<br/> <br/> ---response end---<br/> 401 Unauthorized<br/> Registered socket 3 for persistent reuse.<br/> ] done.<br/> Inserted ‘lh’ into basic_authed_hosts<br/> Disabling further reuse of socket 3.<br/> Closed fd 3<br/> <br/> ---request begin---<br/> POST /controller/ejectNode HTTP/1.1<br/> User-Agent: Wget/1.14 (linux-gnu)<br/> Accept: */*<br/> Host: lh:9000<br/> Connection: Keep-Alive<br/> Content-Type: application/x-www-form-urlencoded<br/> Content-Length: 24<br/> Authorization: Basic QWRtaW5pc3RyYXRvcjphc2Rhc2Q=<br/> <br/> ---request end---<br/> Failed writing HTTP request: Bad file descriptor.<br/> Closed fd 3<br/> Retrying.<br/> <br/> --2012-08-21 17:19:02-- (try: 2) <a href="http://lh:9000/controller/ejectNode">http://lh:9000/controller/ejectNode</a><br/> Found ‘lh’ in basic_authed_hosts.<br/> Found lh in host_name_addresses_map (0x9cb2f48)<br/> Connecting to lh (lh)|127.0.0.1|:9000... connected.<br/> Created socket 3.<br/> Releasing 0x09cb2f48 (new refcount 1).<br/> <br/> ---request begin---<br/> POST /controller/ejectNode HTTP/1.1<br/> User-Agent: Wget/1.14 (linux-gnu)<br/> Accept: */*<br/> Authorization: Basic QWRtaW5pc3RyYXRvcjphc2Rhc2Q=<br/> Host: lh:9000<br/> Connection: Keep-Alive<br/> Content-Type: application/x-www-form-urlencoded<br/> Content-Length: 24<br/> <br/> ---request end---<br/> [POST data: otpNode=n_0@10.17.20.233]<br/> HTTP request sent, awaiting response... <br/> ---response begin---<br/> HTTP/1.1 400 Bad Request<br/> Server: Couchbase Server 2.0.0r_231_gdcd71d5<br/> Pragma: no-cache<br/> Date: Wed, 22 Aug 2012 00:19:02 GMT<br/> Content-Length: 29<br/> Cache-Control: no-cache<br/> <br/> ---response end---<br/> 400 Bad Request<br/> Registered socket 3 for persistent reuse.<br/> Skipping 29 bytes of body: [Cannot remove active server.<br/> ] done.<br/> 2012-08-21 17:19:02 ERROR 400: Bad Request.<br/> Date of First Response Sat, 4 Jun 2011 19:06:03 -0500 Flagged Rank 1904 Time In Status
