• Trying to set up OpenVPN server on a vps

  - by Austin

  I'm trying to set up an OpenVPN server on my VPS for myself when I'm in public places, using this tutorial, http://tipupdate.com/how-to-install-openvpn-on-ubuntu-vps/ However whenever I try to start the server, it gives me this, root@vps:~# /etc/init.d/openvpn start * Starting virtual private network daemon(s)... * Autostarting VPN 'server' [fail] The log contains this Tue Dec 11 10:53:32 2012 Diffie-Hellman initialized with 1024 bit key Tue Dec 11 10:53:32 2012 /usr/bin/openssl-vulnkey -q -b 1024 -m <modulus omitted> Tue Dec 11 10:53:33 2012 TLS-Auth MTU parms [ L:1542 D:138 EF:38 EB:0 ET:0 EL:0 ] Tue Dec 11 10:53:33 2012 ROUTE: default_gateway=UNDEF Tue Dec 11 10:53:33 2012 Note: Cannot open TUN/TAP dev /dev/net/tun: No such file or directory (errno=2) Tue Dec 11 10:53:33 2012 Note: Attempting fallback to kernel 2.2 TUN/TAP interface Tue Dec 11 10:53:33 2012 Cannot allocate TUN/TAP dev dynamically Tue Dec 11 10:53:33 2012 Exiting So obviously it's something to do with the tun, but I don't understand how to fix it.

• Cannot browse remote networks even with WINS configured

  - by paradroid

  As the NetBIOS protocol acts on Layer 2 and so is not routable, In order to enable network browsing of remote networks, WINS has been installed and configured on two domain controllers, both of which are on different networks. The WINS servers seem to be replicating with eachother, and each has 127.0.0.1 set as the Primary WINS Server in each of their LAN interface properties, with nothing entered for Secondary WINS Server. The DC which holds the PDC Emulator FSMO role has the Computer Browser service running and set to Auto start, and it has the WINS/NBT node type network setting at 0x8 (H-node - Hybrid node). Remote network browsing does not work. Is the WINS/NBT node type correct for this scenario? The reason why I think it may not be the right one is because I set the DHCP Server's 046 WINS/NBT node type option to 0x8 as well, after which the DHCP clients started to disappear from the Network folders. When that option is not set, does it default to B-node (Broadcast node)? Or could it be a problem with the WINS servers setup?

• SQL Full-Text indexing not populating

  - by Sam

  We installed a clustered SQL 2005 installation on windows 2008 and reattached our san drives from another machine and restored to do a migration to new hardware. There have been a few minor issues, but this one has me stuck. Trying to populate Full-Text indexes is not working. I create a basic table with some simple text in a new database and get the same results as old indexes. 2010-09-27 10:30:46.85 spid19s Informational: Full-text Full population initialized for table or indexed view '[SQL_DBA].[dbo].[CIS_Report_Executions]' (table or indexed view ID '1767677345', database ID '5').

Attempt will be made to reindex it. The rebuild/repopulate procedure finishes, but I get zero rows in the index. The .dll in the message is present and the service accounts have access to this. My FTData also has data in it, so it seems there wouldn't be permission issue on this folder. Application throws this error: “PHP Warning: mssql_query() [function.mssql-query]: message: Full-text catalog 'ikm_PageIndex_FText' is in an unusable state. Drop and re-create this full-text catalog. (severity 16) in E:\Inetpub\knowledgebase_insidemesa\lib\database\mssql.php on line 154” A microsoft discussion is the only post I found which had claimed to fix this - said it was registry related, but then didn't post the fix.

• Bare bones backup / restore for single Win 2003 server

  - by s.mihai

  I have a single server, Win 2003 Server and would like to setup a system to be able to perform a bare bones restore if needed. (just plug in a cd or smth and get everything back). Ideally the backup could be performed while the is powered so that i don't have to support downtime during this, and in order to restore i would reboot and use some sort of liveCD Any ideas on this, software and all... ? (backup will be done to a remote FTP server with plenty of bandwidth).

• ubuntu server 10 - slow and can't remove desktop environment

  - by Alex

  i'm running ubuntu server 10.10 with the desktop environment. simple page requests are taking over 5 seconds even when connecting to the server through our local network. i believe this is partially related to having the desktop environment installed, as the server worked faster (but not as fast as it should considering that it's on the local network), but tasksel fails every time (aptitude failed 100). my knowledge of networking and linux in general is limited. would really appreciate ideas on how i can troubleshoot this problem. oh also, in the system monitor, one of the processors is almost always around 100%. i doubt this is normal too....

• Teamed network cards on a Proliant Server

  - by Matt

  We have 4 network cards in a Proliant server with Server 2008R2 running Exchange 2010, with 1 card set to a static IP address and the other 3 set to DHCP. I just need some clarification as I have not teamed network cards. Do all the network cards need to have a static IP when I set as a team. The connection that has the static IP is the IP that I need to use for the Server. Is it possible to set the teamed cards to the same static IP or do I have to change the static IP to another IP then use it for the teamed IP? I will be using HP Network Configuration Utility to set this up.

• Running Debian as guest operating system on a Hyper-V VM

  - by kce

  Hello. Layer-9 considerations are prompting a migration from Citrix XenServer to Hyper-V as our shop's virtualization platform of choice. This will require me to migrate our existing virtual machines from XenServer to Hyper-V. A hand full of these VMs are running Debian. Unfortunately, Debian does not seem to be on the list of approved/supported guest operating systems. In fact it seems that running Debian as a guest operating system of is rather difficult, although apparently not impossible. I have two interrelated questions: Does anyone have any experience running a Debian guest on Hyper-V? Is it one of those things where it just will not work at all or is more along the lines of "it will probably work fine, but we won't support it". Any experience here, positive or negative, would be helpful. How much of a bad idea is it to deviate from Hyper-V's list of supported guest operating systems? Again, is it either basically asking for Bad Things (TM) to happen or is just another instance of "it will probably work fine, but we won't support it"? Or is it somewhere in the middle? Thank you.

• install SSH2 (server?) on FreeBSD

  - by Robert Cabri

  At work we have freeBSD testmachine. And we have a PHP script that uses SSH2 protocol to connect with the freeBSD server. With this script I'm not able to connect to the freeBSD server. I wanted to install it, but I'm not sure where to find the right source to compile. The connection can be made with a different machine, but isntalling a new distro isn't the solution right now. I can connect to the server over ssh, but not with the ssh2 protocol in PHP (http://nl.php.net/ssh2).

• Can a Windows 2003 Active Directory server act as a NTP server?

  - by Rob Nicholson

  Within our LAN, there are two Windows 2003 servers with the Active Directory role. Both these servers have the time service configured to query NTP servers on the internet for the accurate time. That works fine. I've just installed XenServer v5.6 and it's asked me for the IP address of an NTP server. Without tweaking the firewall, I cannot configure this server to reference an internet based NTP server. But can I configure it to use the IP address of the internal AD servers, i.e. do AD servers also act as NTP servers to other computers? Thanks, Rob.

• Get OWA and ActiveSync working on server using HTTP redirect in IIS 7

  - by eric

  We have two servers on our LAN. One is a Windows 2003 Server domain controller running Exchange 2003. The other is a stand-alone Windows 2008 server running IIS 7. Our company website runs on the IIS 7 (2008) server, so the firewall forwards port 80 to this. How can I get OWA and ActiveSync to work with this setup? And without using SSL. I have tried setting up a website on the IIS 7 box (mail.ourdomain.com) and using HTTP redirect to point to http://mailserver/exchange, but this doesn't work. Do we have to purchase an SSL certificate for this to work?

• Improving server security [closed]

  - by Vicenç Gascó

  I've been developing webapps for a while ... and I always had a sysadmin which made the environment perfect to run my apps with no worries. But now I am starting a project on myself, and I need to set up a server, knowing near to nothing about it. All I need to do is just have a Linux, with a webserver (I usually used Apache), PHP and MySQL. I'll also need SSH, SSL to run https:// and FTP to transfer files. I know how to install almost everything (need advice about SSL) with Ubuntu Server, but I am concerned about the security topic ... say: firewall, open/closed ports, php security, etc ... Where can I found a good guide covering this topics? Everything else in the server... I don't need it, and I wanna know how to remove it, to avoid resources consumption. Final note: I'll be running the webapp at amazon-ec2 or rackspace cloud servers. Thanks in advance!!

• Dedicated Server emails ending up in Junk

  - by Pasta

  I have a dedicated server that works fine. Recently I added a new domain with a new dedicated IP address. The emails from the webserver gets sent out from the primary IP address which is different from the IP address of the domain. This causes the emails to end up in the Junk email folders. Is there anything I can do changing the SMTP server to the new IP address or configuring send mail? I need this for my php server on centos.

• mysql.sock problem on Mac OS X, all Zend products

• Transferring websites from x64 to x86 server

  - by Ke

  Hi, I run a x64 staging server here along with the following: Solr Java etc. However, I am about to get a linode vps for production and quickly realising that x86 is the way to go for their lowest RAM package (thinking to upgrade later). My staging server is x64 with 12gb ram, so going down to 300mb ram is going to feel devilishly slow ;/ Here are my questions: 1) Will I have problems transferring my scripts, dbs etc from a x64 to x86 server? e.g. solr indexes 2) Is it worth going for the x86 package? I am probably going to upgrade later down the line and x64 might be better for the servers with more RAM? should I stick with x64 instead as there isnt much difference when using with low RAM? Cheers Ke

• OpenLDAP server logs filled with "TLS negotiation failure"

  - by WildVelociraptor

  I recently migrated an old OpenLDAP setup to a newer server, with a more robust certificate setup. Currently, most hosts are required to verify the cert matches the host: tls_checkpeer yes TLS_REQCERT always In the server logs, there are multiple occurences of: Nov 6 10:45:08 <servername> slapd[1773]: conn=2785646 fd=35 closed (TLS negotiation failure) These errors appear from multiple hosts, but there don't seem to be any issues actually logging into those servers with an LDAP account. Does anyone know what would cause these errors? The server is running Ubuntu 12.04.2, and OpenLDAP version 2.4.28. The cert was generated using GnuTLS.

• IP Blacklists and suspicious inbound and outbound traffic

  - by Pantelis Sopasakis

  I administer a web server and recently we had our IP banned (!) from our host after they received a notification e-mail for abuse. In particular our server is allegedly involved in spam attacks over HTTP. The content of the abuse report email we received was not much informative - for example the IP addresses our server is supposed to have attacked against are not included - so I started a wireshark session checking for suspicious traffic over TCP/HTTP while trying to locate possible security holes on the system. (Let me note that the machine runs a Debian OS). Here is an example of such a request... Source: 89.74.188.233 Destination: 12.34.56.78 // my ip Protocol: HTTP Info: GET 'http://www.media.apniworld.com/image.php?type=hv' HTTP/1.0 I manually blacklisted this host (as well as some other ones) blocking them with iptables, but I can't keep on doing manually all day long... I'm looking for an automated way to block such IPs based on: Statistical analysis, pattern recognition or other AI-based analysis (Though, I'm reluctant to trust such a solution, if exists) Public blacklists Using DNSBL I actually found out that 89.74.188.233 is blacklisted. However other IPs which are strongly suspicious like 93.199.112.126 (i.e. http://www.pornstarnetwork.com/account/signin), unfortunately were not blacklisted! What I would like to do is to automatically connect my firewall with DNSBL (or some other blacklist database) and block all traffic towards blacklisted IPs or somehow have my local blacklist automatically updated.

• SVN: Error validating server certificate for svn hook linux

  - by Dr Casper Black

  Hi, I managed to setup a SVN (over SSL) server and TortoiseSVN client on Win. I made a Post-Commit Hook for test project. The Post-Commit will update the web dir so the App in PHP can be executed with the newest version. It all works when done over shell. The only problem is, when i commit the changes over the client in Win the change is commited but HOOK throws error post-commit hook failed (exit code 1) with output: Error validating server certificate for 'https://SERVER_IP:443': - The certificate is not issued by a trusted authority.

• Microsoft Office "Read-only" warning not appearing on Samba shares on Mac OS X Server

  - by bongo

  Hi, some of my users don't get the "read-only" warning (but "read-only" does appear on the title bar and the document is indeed opened read-only) when opening Office 2007 documents already opened by another user. We run the samba share off an XSan volume under Mac OS X 10.5.8 Server. Strict locking is on but oplocks are off (from Server Admin). At home, with a simple samba share in 10.6.3 server, it works correctly. Any ideas? or is this a 10.5.8 behavior?

• Windows 2008 server smart card security module problem

  - by chris13work

  Hi, I've got a smart card reader and a server application using it as a security module. If I run it under DOS prompt, everything is fine. The server is running and clients can connect to it. I tried to install the server as window service and start it. The server starts but always gives back authentication error because it cannot call the smart card to do encryption. Then I tried to start it with task scheduler and set the trigger factor as "on startup". The server starts also but still cannot access the smart card reader. Then I tried remote desktop to the machine and run the server application under DOS prompt. Same error is returned. The situation is that the smart card reader only works under active console desktop environment. In the server application, WINSCARD API is used to access the smart card reader. Any suggestion so that we can access the smart card reader in running services? OS: Windows Server 2008 Smart Card Driver: Windows USB smart card Reader Smart Card API: WINSCARD

• Website hosting from home - IIS6

  - by Paul

  I'm wanting to host a few websites from home, primarily because I'm using some BETA Microsoft software (.NET 4 and EF) and don't want to install it on my production server which is hosted at eukhost.com. Basically, I'm completely new to this sort of thing. So far, here is what I've done: Registered the domain name at namecheap.com (let's call it mydomain.com) Gone to "Nameserver Registration" in the panel and entered my IP address for the NS1 and NS2 records (let's say the IP is 0.0.0.0). Gone to "Domain Name Server Setup" and entered ns1.mydomain.com & ns2.mydomain.com Forwarded requests from port 80 to my internal IP (let's say 192.168.1.254) Created the website in IIS (I'm just testing with a single website so far, so have not created any host header values) Now, if I type in the IP address (http://0.0.0.0) I get the site as expected. However, if I enter http://www.mydomain.com I get an error saying "DNS Error - Cannot find server". I'm aware that there is a service from DynDNS that will automatically change the IP if I have a dynamic address, however my IP has remained static since I installed the ISP (since October) so I don't need this. Is there any way that I can get the DNS to work just by configuring IIS or something in Windows? I don't really want to have to pay for any 3rd party service. Thanks,

• SSL and IP addresses on a dedicated server

  - by spike5792

  I've just moved from a shared web hosting server operating on WHM/cPanel running six domains with 1 dedicated IP address. 1 of the 6 domains has an SSL certificate. I have since moved to a dedicated server also with 1 dedicated IP and running cPanel/WHM with the same six domains. I want 1 of the domains to have the SSL certificate but I am being told that it's not possible unless I buy another dedicated IP address. I want to question the hosting provider on this but they haven't really acknowledged it - they've just kept saying that it needs its own IP as the IP I am currently using is shared between my six domains. Does anyone have any experience of this and tell me why my new expensive dedicated hosting provider can't setup SSL using the certificate as I had done before on my shared server?

• Exchange Server Contact Categories - How to Remove/Update All

  - by ben

  I've been tasked with cleaning up our companies contact database sitting on our Exchange Server 2003. The rub is this database of contacts has been neglected for the past couple of years and is now a bit messy. My issue is I have say a person named 'Bob Smith', and Bob is listed in multiple categories, 'Students' and 'Student'. I would really like to remove the 'Student' category from Bob and anyone else out there that has the same category. My question is, is there an easy way to edit the master category lists for contacts on the exchange server? I feel like I am missing something simple here since if I were playing with the categories that I use, to say organize email its very easy to do so, but I can't seem to find the proper way to do it for categories that are up on the server. I'm attempting to work through Outlook 2007 and Exchange 2003. Any insight would be very helpful as I really don't want to change 8000+ contacts by hand.

• pfsense, active directory, local domain

  - by Dalton Conley

  First things first, I have no idea what I'm doing. Certainly not afraid to admit that.. but here is my network setup. I have 2 servers, one of them in a domain controller. Both are running windows server 2008. They have replicated directories. Each server is at a different location and has its own firewall for the network at that location. Both firewalls are using pfsense. Recently a firewall went down and my coworker reinstalled pfsense, and everything seems setup correctly. Again, I have no idea what I'm doing so I'm not sure. I have records from when the previous IT person had setup this network and the firewall settings are the same but those records could have been extremely old. Now, I have a domain name for my network.. we'll call it "mydomain.net". I use to be able to access this domain name and it would bring up the servers replicated drives(i.e. \\mydomain.net). Now I cannot. I can however access the servers individual host names on my network(i.e. \\server1 , \\server2). We didn't change anything on the server which is what makes me think its something to do with the firewall. I know this is probably a very general question and I don't have a lot of detail to add but could anyone give me some insight on to what could be causing this, or some debugging techniques I can apply to this? I'm a programmer, not a network administrator.

• Exchange Server 2007 Transport Errors -- SMTP Session Hangs

  Hello, I was doing some changes to the server (writing an Transport Agent). After trying to install it, I started to get some errors. Now, when connecting to the SMTP server the session hangs just after finishing the DATA section. I'm not sure what happened, I disabled my transport agent and uninstalled it, then restarted the server. The problem persists. In the Event Viewer, four of the same errors show up: Source: FSCTransportScanner Category: Scan Error Event ID: 5021 Description: Unable to retrieve internet monitor interface.
