I want to use an https nginx to proxy a non-secured nifi server running in the same box.

So far the closest I get is by using this configuration:

location ^~ /nifi {
            proxy_set_header X-ProxyHost localhost;
            proxy_set_header X-ProxyPort 6969;
            proxy_set_header X-ProxyContextPath /nifi;

            proxy_pass http://localhost:6969/nifi;
    }

In nifi I get the exception:

2018-11-24 17:40:19,473 ERROR [NiFi Web Server-20] o.a.nifi.web.api.config.ThrowableMapper An unexpected error has occurred:
javax.ws.rs.core.UriBuilderException: The provided context path [/nifi] was not whitelisted []. Returning Internal Server Error response.

Any hints?

Can anybody confirm this would work ?

I have two MX-configured DNS records to handle smtp and pop. I'd like to implement a 'mailing list' server in another machine so:

Would it do any harm the fact that this third mail server has no user inboxes ?

Would the mails that it sent be acknowledged as valid by the receiving servers given it's ip/name is present as a MX record ?

I recently downloaded a certificate from startssl and I'm trying to enable ssl on my tomcat 7.0.6 (I didn't generate de req file). I configured and when I tried to start it, the following error showed up:

java.io.IOException: Alias name ssltest does not identify a key entry

When I list the certificates in my keystore, I find that "ssltest" has "Entry type: trustedCertEntry" whereas "tomcat" has "Entry type: PrivateKeyEntry". What step am I missing ? (I already imported ca.pem and sub.class1.server.ca.pem.

Thanks in advance

I recently stopped the postgresql database (that was working perfectly), and after a couple of days, when I try to start it, I get the errors:

2011-01-03 23:56:27 CLST LOG:  could not translate host name "localhost", service "5432" to address: Name or service not known
2011-01-03 23:56:27 CLST WARNING:  could not create listen socket for "localhost"
2011-01-03 23:56:27 CLST FATAL:  could not create any TCP/IP sockets

I'm running Ubuntu 9.1, and I'm using the usuals

/etc/init.d/postgresql-8.4 start and stop

Any hints ?

I'm running ubuntu 9.10 which has gcc4 (libstdc++6) installed, and I need to install a program that requires libstdc++5 that comes with gcc3. I don't see gcc-3 listed when I run "apt-cache search" so:

  • Is it necessary to install gcc-3 to achieve libstdc++5 ? If so where can I get it ?
  • Is there a way to install just libstdc++5
  • Would a soft link to libstdc++6 do or is it not recommended ?

Thanks

I have an apache 2 web server working with a tomcat 6 servlet container running on ununtu 9.1, integrated via mod_proxy.

I have the following time mismatch problem:

  • When apache log to its access-log file, the date/time is correct.
  • When a grails app running on tomcat inserts date-related information in the DB, the time is three hours ahead

Any tips on how to fix tomcat's datetime problem ?

Thanks

I'm running a Linux server named S1 in a "cloud" server, and when tomcat 6.0.24 starts, I get the exception:

org.apache.catalina.connector.Connector pause
SEVERE: Protocol handler pause failed
java.net.UnknownHostException: S1: S1
    at java.net.InetAddress.getLocalHost(InetAddress.java:1353)
    at org.apache.jk.common.ChannelSocket.unLockSocket(ChannelSocket.java:485)

Which then leads to:

ERROR ehcache.Cache  - Unable to set localhost. This prevents creation of a GUID. Cause      was: Sjira1: S1
java.net.UnknownHostException: S1: S1
    at java.net.InetAddress.getLocalHost(InetAddress.java:1353)
    at net.sf.ehcache.Cache.<clinit>(Cache.java:143)

My hosts file is:

127.0.0.1     localhost localhost.localdomain
(valid-ip-address)     S1 S1.(valid domain name)
  • ping S1 and S1.(valid domain name) return valid ip address
  • nslookup S1.(valid domain name) returns valid ip address
  • nslookup S1 throws ** server can't find S1: NXDOMAIN

Any ideas about how to fix this ?

Thanks
