    - by Charles
    HOW CAN I MAINTAIN Gigabit Ethernet integrity given this situation: What I have to work with: ** AC-router w/4 port gigabit N-600 router w/4 port gigabit Switch w/8 port gigabit All PCs have gigabit NICs 4-port POE injector at gigabit (all wiring = Cat 6) **Problem = Printer @ 10/100 (built-in) Printer @ 10/100 (built-in) Scanner @ 10/100 (built-in) Printer @ 10/100 (built-in)** What device (not setting up a PC) or configuration would I have to incorporate to get gigabit going given those devices? WILD SHOT: IS THERE SUCH A THING AS A SWITCH THAT CAN ACCOMMODATE THIS? THANK YOU ALL

  • Tutorial for configuring OpenVPN [on hold]

    - by user2699451
    I have been through 10+ tutorials on setting up a OpenVPN, and each tutorial gives a different problem... Does anyone know of a decent and helpful website/tutorial which I could go to to get it set up? I have been battling through it for almost 2 months now. Yes, I have also bugged forums.openvpn, but I think I have "reached my post limit" with them. I have to configure it remotely via ssh. UPDATE: okay, I have been asked to be more clear on the topic I followed this tutorial (as a example) - http://www.servermom.com/how-to-build-openvpn-server-on-centos-6-x/732/ I had no issues setting up, etc. except when I boot into windows and run the OpenVPN GUI Client, it connects and gives this error: WARNING: Bad encapsulated packet length from peer (21331), which must be 0 and <= 1576 -- please ensure that --tun-mtu or --link-mtu is equal on both peers -- this condition could also indicate a possible active attack on the TCP link -- [Attemping restart...] Here is my server config: port 1194 #- port proto udp #- protocol dev tun tun-mtu 1500 tun-mtu-extra 32 mssfix 1450 reneg-sec 0 ca /etc/openvpn/easy-rsa/2.0/keys/ca.crt cert /etc/openvpn/easy-rsa/2.0/keys/server.crt key /etc/openvpn/easy-rsa/2.0/keys/server.key dh /etc/openvpn/easy-rsa/2.0/keys/dh1024.pem plugin /usr/lib64/openvpn/plugin/lib/openvpn-auth-pam.so /etc/pam.d/login #- Co$ #plugin /etc/openvpn/radiusplugin.so /etc/openvpn/radiusplugin.cnf #- Uncomment$ client-cert-not-required username-as-common-name server 10.8.0.0 255.255.255.0 push "redirect-gateway def1" push "dhcp-option DNS 8.8.8.8" push "dhcp-option DNS 8.8.4.4" keepalive 5 30 comp-lzo persist-key persist-tun status 1194.log verb 3 and my client config: client dev tun proto udp remote [server ip] 1194 # - Your server IP and OpenVPN Port resolv-retry infinite nobind tun-mtu 1500 tun-mtu-extra 32 mssfix 1450 persist-key persist-tun ca ca.crt auth-user-pass comp-lzo reneg-sec 0 verb 3 OpenVPN Client Log: Thu Oct 31 11:51:29 2013 OpenVPN 2.0.9 Win32-MinGW [SSL] [LZO] built on Oct 1 2006 Thu Oct 31 11:51:44 2013 IMPORTANT: OpenVPN's default port number is now 1194, based on an official port number assignment by IANA.

  • "Upgrading" from OpenIndiana 151a to Solaris 11.1 using IPS

    - by syneticon-dj
    I wonder if it would be possible to "upgrade" from an OpenIndiana install (151a) to the current Solaris release (11.1) using the IPS. What I have done so far: added the "solaris" publisher using pkg set-publisher -g http://pkg.oracle.com/solaris/release/ solaris removed the "opensolaris.org" and "openindiana.org" publishers (just to make sure) tried to start the update process using pkg update --accept or explicitly setting the release name pkg image-update --accept --be-name Solaris_11 - both backed out stating there are "No updates available for this image".

  • How can I get HAProxy backends to include a path

    - by Michael Neale
    When using HAProxy for virtual hosting, I can see how to use the Host from the header at the front end to decide what backend to route to. However, is it possible to make the back end be a URL which includes a path (not unlike what you would do with apache or nginx when setting up virtual hosting). http://www.techrawr.com/tag/haproxy/ - shows most of it. But what if the back ends were on the one server but with backend1 and backend2 as the servers?

  • What PHP configuration and extensions are recommended for speed, efficiency and security?

    - by Sanoj
    I am setting up an Ubuntu server with nginx and PHP. I have read about many different configurations and extensions that could be added and it is pretty hard to know about all of them. I would like to hear from you, sysadmins, what PHP configuration and extensions do you recommend? I have read about: Suhosin for security Alternative PHP Cache for speed and efficiency Memcache for speed and efficiency PHP FastCGI Process Manager for speed and efficiency But I have no idea if they are good or not, and if I should use them together.

  • How to solve/disable spam sending with my postfix server on linux

    - by Dukla
    I am quite new in setting up e-mail server on linux - I barely set up the whole think to get it working and connected it with my domain and php script which uses PHPMailer 5.2.1. In my setting I am using smtp server from my web provider (domain) and all e-mail which are not defined (trash) are sent on one simple address like I have address [email protected]. So when somebody will send email to [email protected] it will be forwarded again to [email protected] even in case of failure. I am receiving emails like: Hi. This is the qmail-send program at comercio.interone.com.br. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <[email protected]>: Sorry, no mailbox here by that name. (#5.1.1) --- Below this line is a copy of the message. Return-Path: <[email protected]> Received: (qmail 49156 invoked from network); 25 Jun 2012 07:34:57 -0300 Received: from unknown (HELO S0106602ad08df877.no.shawcable.net) (70.66.34.103) by hosting.interone.com.br with SMTP; 25 Jun 2012 07:34:57 -0300 Message-Id: <20120625034039.B45C12DCC3B13A22F261@GANDERTO-015445> From: Ezra Whitehead <[email protected]> To: toa <[email protected]> Reply-To: Jamey Mcconnell <[email protected]> Subject: Welcome toa Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Visit our shop http://44090.medicneed.ru/ 113B726C73560AA41A68163AA474D5F1476 0225770686522678 As you can see there is line From: Ezra Whitehead <[email protected]> I am sure I did not send this email from my domain.com with some Davis8FB name and some russian page. This is just one of many and only NOT-delivered e-mails - there can be much more which has been sent successfully! What do I have wrong in my settings? How can I make it right? What should I do to prevent these messages to send? Where should I look? Thank you all.

  • Windows Live Mail and Palm Pre

    - by itprofessionalsgroup
    Has anyone had any luck getting Windows Live mail to sync with a Palm Pre with WebOS 1.1? I have tried the manual setup options setting up the pop3 incoming server on port 995 with SSL encryption and the smtp out going server on both ports 25 and 587 with TTL encryption. It acts like it is connected, but it just keeps wanting to refresh and never shows anything in the inbox.

  • pendrive automount not working

    - by Delirium tremens
    There are lots of ways to disable pendrive automount. I used one, but regreted, forgot which one and now need to reenable pendrive automount. It may have been a changed setting after pressing a button while booting Ubuntu or a deleted folder named something20090101 or 01012009something or whatever as long as it's a word and a date... If I don't want pendrive viruses, it's disable autorun, but keep automount enabled, right? blush

  • network endpoint accessible via hostname only, not address?

    - by Dustin Getz
    someone told me that this piece of network hardware (NAS) has a security setting such that it can only be accessed by hostname, not by IP address. I don't understand, as I thought DNS resolved the hostname to an address on the connecting client's side, then at protocol level always used the raw address, so how can this 'security' measure be possible?

  • phpmyadmin login should not expire on ubuntu 10.04

    - by mit
    On ubuntu 10.04 the phpmyadmin config is a little bit scattered. I want to set the loginexpiration time to zero, should never expire, this is a secured setup behind a firewall. I think it is 3600 by default but cannot find the setting. Where is it? Edit: I actually changed it in /etc/phpmyadmin/conf.inc.php which seems the recommended place for ubuntu. The other files mentioned below might be overwritten on updates.

  • How do I remove the on screen keyboard from the logon screen in Windows Remote Desktop Server 2008 R

    - by Gomibushi
    The on screen keyboard (OSK) from the "ease of access" tools pops up on EVERY connect to the server, even if you have not activated it. I can't seem to find a control panel or reg setting to switch it off. It is VERY "in your face" for linux users who connect at lower resolutions and do not provide all credentials, but have to type username and password. I'm running a 2008 R2 Terminal Server/Remote Desktop Server.

  • User cannot Add or Remove people from a distribution list using outlook.

    - by Matt
    Recently we moved across a user and a distribution list from Exchange 2003 to 2010. The user used to be able to add and remove from a distribution list within Outlook. I have added them to the Managed by list in Exchange in the distribution list, but to no avail. They are getting an error message saying You do not have the sufficient permissions to perform this operation on this object. I cannot seem to find the setting to allow the user permissions.

  • Remote Web in SBS 2011 Essentials (SSL Issue)

    - by MetalSearGolid
    I am having an issue setting up Remote Web in SBS 2011 Essentials. Everything works except Remote Desktop, which keeps giving me SSL cert errors. Is there a way to override the TS Gateway's decision to not allow cert errors? If not, the specific error I am getting is that Remote Desktop is trying to connect using the DNS short name of our domain controller, but the certificate uses the FQDN, and as such, it reports an error and the connection never happens. Any ideas?

  • Node.js on via DynDNS

    - by Azincourt
    I have never used Node.js but since I am developing a browsergame that needs (almost) "realtime" communication, I am planning on using Node.js for this. To get started, I wanted to use a home server (normal computer) that is conntected to a dynamic IP via DynDNS. Are there the disadvantages using such a setting? What is the best way in combination with Node.js to store game status for a online game session?

  • IIS Configuration Synchronization for Web Server Farm?

    I'm wondering if there is any good/easy way to get the IIS configurations synchronized? I'm going to be setting up a pair of IIS Servers with Network Load Balancing. I can get the data files (html, etc) synchronized all fine and well, but I'll be adding new Websites fairly often and I'd like to avoid doing the IIS configuration on multiple servers.

    My router is a Wag200g with openwag firmware. My laptop is connected to the university's internet through an ethernet cable and i have to set the browser proxy settings to connect.

Or am i approaching this the wrong way?
