And then i change it to my domain : hostname domain.com And i started to installing WHM / cPanel as explained in here : http://etwiki.cpanel.net/twiki/bin/view/AllDocumentation/InstallationGuide/InstallingCpanel It's installed very well. And the i reboot my server. After rebooting, i was execute this command for open WHM's 2087 port : iptables -I RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 2087 -j ACCEPT Now i'm trying to browse domain.com:2087 i'm getting Server (centos) not found .I noticed it's forwarding to my old hostname (centos) . And then execute this command to verify me hostname hostname it's returned "centos" again. I'm not sure, why it's returned to old hostname. (I think it returned to old hostname after rebooting) .

  • Why doesn't update-manager allow me to upgrade distribution?

    - by spoulson
    I have an Ubuntu 9.04 PC behind a corporate firewall and proxy server. This requires that in order to get update-manager to fetch and apply updates, I must set the proxy and authentication settings in the Synaptic network configuration. Once done, I can check for updates and things work smoothly (except I don't get popup notifications of new updates, must manually check periodically). However, distribution updates just don't show up in update-manager, such as the newly released 9.10 Karmic Koala. I had the same issue in upgrading 8.10 to 9.04 and solved it by downloading and upgrading from the 9.04 ISO. What do I need to do to upgrade to 9.10 using the standard update-manager UI?

  • How to prepare and secure a Macbook Pro for work/office?

    - by sunpech
    I plan to use my Macbook Pro at work/office. Before I do so, I will need to speak to my manager on how to properly prepare and secure it since this is the first Mac that will be regularly used on the network in the office and company intranet. The intranet comprises mostly of PCs running Microsoft Windows XP, Server 2003, and Windows 7. So there's definitely a Microsoft-only culture in the office, and the infrastructure/networking team are mostly unfamiliar with non-Microsoft technology and software. What steps and software would I need to prepare and secure my Macbook Pro for work/office? Antivirus/Spyware software for Mac required/necessary? What options do I have to encrypt files, or possibly the whole drive/partition? What network/firewall settings should be enabled?

  • Multiple WAN interfaces in same subnet on Sonicwall NSA220?

    - by Ttamsen
    (eta salutation, which keeps getting eaten.) Hi, all. I see a bunch of related questions, so I'm hesitant to ask, but: I have a situation where I have a Sonicwall NSA220 serving as firewall/router for two internal subnets to two external WAN connections. In some locations this is two separate ISPs. In others, it's the same ISP but with multiple circuits. The problem is that one ISP has been unable to provide unique subnets for each WAN interface. Is there any possibility that I might be able to bond the two WAN interfaces into a single virtual interface, and then use source-routing to get internal subnets communicating out the appropriate physical interface? Or even just use traffic-shaping to give each internal network appropriate shared bandwidth? I haven't found anything in the docs, but it seemed like it might be worth asking. Thanks for any help! -Steve.

  • nsclient++ intermittent connection refused on same subnet

    - by jshin47
    I have setup Nagios and nsclient++ on a number of my Windows servers. They are all in the same subnet so no routing or firewall stuff is taking place in between the endpoints, and I have verified that the firewalls on the servers are not causing trouble. The problem is that the scheduled checks sometimes fail with "connection refused" and sometimes work! It is a frustrating problem to resolve because I do not know what to look for. One place I did look is in the nsclient++ logs, where I am seeing this recurring error: ...\trunk\modules\CheckSystem\PDHCollector.cpp:148: Failed to query performance counters: \238... This sounds promising, but I couldn't find much on Google about this error as it pertains to NSClient++

I added a rule to the windows firewall that all connections to that port are allowed but it still doesnt work. there is so many things in google that didnt help me, thats why I am asking specifically. I do acutally not know how to google for that right because i am not that into server configs and so on. Can anybody help me, what I have to do, to be able to access that port? From outside.

  • PostgreSQL: performance descrease due to index bloatper

    - by Henry-Nicolas Tourneur
    I'm running a PgSQL 8.1 on a CentOS 4.4 system (not upgradable unfortunately). There's a Java app running on top of the PgSQL daemon and we got to reindex the database every 2 months or so. Also important: the database isn't growing. It looks like the bloat is now coming faster than before and this tends to increase. My config is available here, autovacuum daemon is enabled and running quite often: pastebin.com/RytNj7dK You can also find the output of this query wiki.postgresql.org/wiki/Show_database_bloat 3 hours after running reindex: http://pastebin.com/raw.php?i=75fybKyd 72 hours after running reindex: http://pastebin.com/raw.php?i=89VKd7PC Does anyone have any idea what should I tweak to get rid of that growing bloat? Thanks for your help PS: due to antispam prevention system, I had to remove the first 2 http:// prefixes for my two first links.

  • Internet wireless connected with limited access, windows vista

    - by r0ca
    I had some malware in my computer so I did a bit of manual work to remove it including resetting TCP/IP. Now the malware is gone. I can see my home wireless network and I can get connected to it but when connected I get the Internet wireless connected with limited access message. When I go to the IE I cannot browse. When I tried to ping 192.168.1.1 I got an Error Code 1231 Unconnected Network Problem. I have deactivated my Windows firewall as I thought it could be hyperactive security. Still no luck. I have Norton but it is not active, I have also Avast and AVG installed but they are not active. Any ideas?

  • Can i safely block all ports on my sever

    - by Saif Bechan
    I have a web server running pleks and get attacked a lot every day. I configured a firewall, and there are some predefined services such as www, and ftp, etc. I am planning to block all the ports except for the www port and the PLESK port. When I need ftp or ssh access for example i will open the ports in PLESK and then start to work. Is this a good thing to do or are there some downsides on doing this. There are some ports I am not sure of, such as SMTP,POP3,IMAP, DNS. Can i close these ports or is there no need to do so.

  • vncserver too many security failures

    - by cf16
    I try to connect to my vncserver running on CentOs from home computer, behind firewall. I have installed Win7 and Ubuntu both on this machine. I have an error: VNC conenction failed: vncserver too many security failures even when loging with right credentials (I reset passwd on CentOs). Is it something regarding that I try as root? I think important is also that I have to login to remote Centos through port 6050 - none else port works for me. Do I have to do something with other ports? I see that vncserver is listening on 5901, 5902 if another added - and I consider connection is established because from time to time (long time) the passwd prompt appears,... right? please help, what to do? even if prompt appeared and I put correct password I get: authentication failure. how to disable this lockout for a testing purposes?

  • Wi-Fi connected but can't go to any site

The issue started a few weeks ago, so I've been troubleshooting since then in vain. There's no virus, and I already used System Restore. In Wireless Network Connection Status, the received activity is greater than the sent activity. I turned off Windows Firewall and still no Net access. My ping tests: How do I fix this?

    Ive been racking my brain with this all evening. Power went out with a tstorm today, started back up my server... running apache and a team speak server on it. TS is great, cant see my web page outside my network! Firewall is disabled on the pc running it (centos btw), apache is running and working. correct ports are forwarded on my router (my isp blocks port 80). Ive tried changing ports, pretty much everything i can think of. httpd.conf is pointing to the correct addy and port, and my domain is pointing to the correct external ip. Im at a loss, any ideas out there?

  • Can't perform ODBC connection to MySQL server on local network

    - by Emmanuel
    I have a wamp server running on LAN ip address 192.168.1.101 . From the browser on my PC which is on the LAN I can access the webserver and have as well set the phpmyadmin.conf file to be able to access the phpmyadmin interface. This works smoothly. On the wamp server I have a database which I'd need to access from any PC on the LAN using the MySQL Connector/ODBC. The problem is that I do not manage to setup the connection correctly. Here are the paramenters I use: Data Source Name: test_connection Description: test conenction Server: 192.168.1.101 Port: 3306 User: root Password: Database: The error message I get is the following: Connection Failed: [HY000][MySQL][ODBC 5.1 Driver]Can's connect to MySql server on '192.168.1.101' (10060) Would anybody have a hint to set up correctly the connection?

  • Filemaker 10 Advanced sending email via script & SMTP

    - by Sean
    We are using a windows server box to run the databases but we have found via the headers that the emails are send from the local workstation. We have moved to a new email system and have set up a local linux server to securely send email out of our network to devices that do not support new protocols and encryption. But once we set up the script in filemaker 10 advanced (the local machine os x) we set it to the ip of our local box with no authentication but it does not send out an email. It creates a connection we see in the logs on the linux box but nothing more, additionally you can start a telnet connection with no issues. We have also made sure that there are no additional issue that we can see in our firewall policies. Any ideas where we should start? Does Filemaker 10 advanced log errors anywhere because I could not find any log files.

  • Cloud Computing - Multiple Physical Computers, One Logical Computer

    - by Koobz
    I know that you can set up multiple virtual machines per physical computer. I'm wondering if it's possible to make multiple physical computers behave as one logical unit? Fundamentally the way I imagine it working is that you can throw 10 computers into a facility one day. You've got one client that requires the equivalent of two computers worth, and 100 others that eat up the remaining 8. As demands change you're just reallocating logical resources, maybe the 2 computer client now requires a third physical system. You just add it to the cloud, and don't worry about sharding the database, or migrating data over to a new server. Can it work this way? If yes, why would anyone ever do things like partition their database servers anymore? Just add more computing resources. You scale horizontally with the hardware, but your server appears to scale vertically. There's no need to modify your application's infrastructure to support multiple databases etc.

  • bind9 dns proxy

    - by Zulakis
    We are offering multiple SSL-enabled services in our local network. To avoid certificate-warnings we bought certificates for server.ourdomain.tld and firewall.ourdomain.tld. We now created a zone in our local DNS-server in which we pointed the hosts to the corresponding private-ips. Now, each time another record for ourdomain.tld, like for example www.ourdomain.tld or alike are changed, we need to update it on both our public-dns-server AND the local dns-server. I would like our local bind-dns to serve all the information from our public-dns but serve different information for these 2 hosts. I know I could possibly have our private-ips in our public-dns but I don't want that for security reasons. The internet dns-server is being managed by a third party, while we have full control of the intranet one. Because of this I am looking for a solution which lets the intranet retrieve the records from the internet one.
