I run 10 minecraft PE servers using Multicraft and PocketMine for linux which has recently been updated to run on PHP7. Everything works fine on 7 of the servers I updated, but 3 of them will not allow any UDP connections (despite starting and seemingly running correctly), however the same servers when configured to use PHP5 start working perfectly.
I'm running CentOS7 CLI on a dedicated server, and have tried reconfiguring and disabling firewalld to no avail. If I change the port of a broken server to that of a working server everything starts working... so I'm wondering why the switch to use PHP7 causes connections on these ports to fail. I've run netstat etc to see if anything is interfering, but everything looks identical whether they are running PHP5 or PHP7.
The only pattern I can see is that those that don't work are the three highest ports:
Ports that allow connections on PHP5 and PHP7:
19132, 19133, 17171, 20000, 25252, 11111, 12321, 23456
Ports working with PHP5 but not working with PHP7:
33333, 55555, 41414
Any ideas what is going on?
Thanks

I have been given a centos server to lauch eclipse orion code editor. I installed eclipse orion as per the instruction on https://wiki.eclipse.org/Orion/How_Tos/Install_Orion_on_Localhost (steps for linux using jetty server). It works fine on centos browser. The centos os is running on 198.168.1.226. So that I can access the following urls on web browser of centos.
198.168.1.226:8080
localhost:8080
127.0.0.1:8080
0.0.0.0:8080
But when I tried to access the 198.168.1.226:8080 from other local machines on local network, that is not accessible. I searched the StackOverflow Questions like how to make jetty server accessible from LAN? and Unable to access jetty server with local IP address but both are useless for me. How can I fix this situation? Can I fix it editing the code on orion.ini file or need to deal with configuration file or something else?
I have also tried the orion for windows computer but it worked itself for accessing the orion system for any other computer in local network. But I am surprised to face it on centos using the jetty server for setting up eclipse-orion system .
First of all check that have you allowed specific port (8080) from eclispse.
add rule with that port no. in centos iptables as below:-
iptables -A INPUT -p tcp --dport 8080 (adjust according your port no.) -j ACCEPT
I am installing chef-server on this VPS that my friend let me borrow.
I was able to install chef and run chef-server-ctl reconfigure successfully.
I ran into problems because I need to change the iptable rules and I discovered that I cannot find chef-server running on any port or as a service.
When I run chef-server-ctl it seems to pass all the tests, so I know its API is working.
Where can I find that chef is running?
I need to change my iptables so that I can use knife to communicate with chef-server.
First off it sounds like you installed Chef Server, not Chef, important distinction :) Second, there is no specific process called chef-server. The frontend routing is handled by nginx which binds on port 443 and 80 (80 is just a redirector to 443 and can be blocked or disabled if desired). Internally we have a bunch of different smaller services like oc_erchef, bifrost, oc_id, etc. These all listen on localhost and are reached via Nginx.
You have installed Chef server and have reconfigured the server, you can't find a chef-server.
you can run below commands to check all the services that are running chef server
$ chef-server-ctl service-list
bookshelf*
nginx*
oc_bifrost*
oc_id*
opscode-chef-mover*
opscode-erchef*
opscode-expander*
opscode-solr4*
rabbitmq*
redis_lb*
postgresql*
To update the port number you need to update
/etc/chef-server/chef-server.rb - in Chef 11
/etcopscode/chef-server.rb - in Chef 12
nginx['non_ssl_port'] = portnumber
And also how are using knife command? Do you want ssl check to be passed then you need to add a line in knife.rb file
ssl_verify_mode: verify_none

I am working on a CentOS 6.4 64-bit, as root. I am trying to set up the system snmpd agent, so that it listens on a port other than 161, e.g. 8001. I successfully got that on Debian 7.x by just changing the port number in /etc/snmp/snmpd.conf:
agentAddress udp:127.0.0.1:8001
and restarting the service with /etc/init.d/snmpd restart. It was straightforward. However, I tried several things but I didn't manage to do that on CentOS, i.e. snmpd will fail to start.
These are the last two lines written in /var/log/messages when I try to run it with that line in snmpd.conf:
Oct 13 15:47:40 localhost snmpd[4775]: Error opening specified endpoint "udp:127.0.0.1:8001"
Oct 13 15:47:40 localhost snmpd[4775]: Server Exiting with code 1
On the other hand, if I run the program directly, it will start and will happily open port 8001:
/usr/sbin/snmpd udp:127.0.0.1:8001
or:
/usr/sbin/snmpd udp:8001
Both ways work.
I have googled and read about /etc/sysconfig/snmpd, but adding some options in this file did not work either. For info, I disabled iptables (ipdatables -F).
Could anybody help me on this?
Thanks in advance,
Antonio
Running memcached on Ubuntu 12.04 LTS.
My /etc/memcached.conf file is set to only listen to localhost.
i.e. -l 127.0.0.1
But I can still telnet through to it from the outside even though it is set to only listen to localhost. My site really doesn't host any sensitive data whatsoever but I am a bit stumped that the config file doesn't really seem to do its job. I don't really see the need for IPtables. Any easy fix to secure memcached without having to set up IPtables?
Restart the service, you might have made change without restarting
To make more secure do not use the standard port
I installed the newest version of Windows 7.
This is my development box, so I have glassfish installed, which I use for Java applications. Also, I use IIS to run PHP applications. I run both servers on port 80, but never at the same time.
However, since I set up IIS, I can't get glassfish to run. In eclipse, it always gives the following error:
Port conflict: Please stop the server process using the same port as the one used by the Application Server.
A server process is already running on this port but we cannot determine if it's a GlassFish process (lack of info or credentials).If you do not find something else running on this port, check for antivirus software blocking or monitoring this port.
Edit: I tried turning off IIS, and even turned off the IIS feature. Still no luck.
I also ran netstat, and the following are showing up on ports that glassfish uses:
Proto Local Address Foreign Address State
TCP 0.0.0.0:80 NBSDTVL01574:0 LISTENING
TCP [::]:80 NBSDTVL01574:0 LISTENING
Thanks
This turned out to be an issue with my virtual machine. A fresh copy fixed the issue.
this happen because you select the same port number use by the iis and glashfish, i suggest you configure either of the two to use different port number.
