• Fortigate - Accessing a Virtual Server address from several interfaces

  - by Jeremy G

  I am setting up a new application in its own DMZ on our Fortigate 300C firewalls. I have defined a load-balancing configuration for part of the application, and this works fine for traffic coming in from our internal network. However, I would also like this application to be reachable from other DMZs, for inter-application traffic, and from the SSL VPN interface. I can't seem to define the required policy, and it seems this is due to Virtual Servers being bound to the client interface on the Fortigate rather than the server interface (and so my virtual IP is not accessible from any of these other interfaces) Does anyone have an idea how I might go about this ? I guess I could create other virtual IPs for each interface, but this gets complicated to handle as clients need to change the address they use depending on how they are connecting. Thanks, Jeremy G

• Differencing Disks in VirtualBox

  - by PhilPursglove

  I'm struggling to understand how to do differencing disks in VirtualBox v3.1.0. I've created a Windows 2008 Server, but now I want to use that as a base image for a number of other servers. The help file has a description of what differencing disks are, but I can't find where it actually tells you how to do it. In the Storage dialog for a server I found the Differencing Disks checkbox: but when I check it, I'd expect it to then ask which image should be the parent so I could select my base image. Any pointers you can offer would be greatly appreciated!

• Best Solution for Load Balancing NFS File Access?

  - by DairyKnight

  I'm trying to find an optimum solution for accessing the NFS file share in my company. We have a central file server in North America and has 30GB~50GB of updated data everyday. And it's very slow for our Europe and Asia branches to access directly. Therefore, I'm trying to setup two replicate servers in those continents. I'm currently using rsync, but wonder if there exists a better solution acts more like a distributed RAID, which allows the user to transparently access the file whether synced or not. And user request will be dispatched to remote server if the file is not yet synced. I'm now looking into DRBD, but it seems not to have the functionality of auto-dispatching requests. Does anyone know if there's a better solution?

• Amazon ec2 - WildCard Sub-Domain

  - by Sharanc25

  I'm running an ec2 instance on ubuntu running lamp stack. I configured my httpd.conf file to support wildcard sub-domain but it didn't work. My httpd.conf file NameVirtualHost * <VirtualHost *> DocumentRoot /www/example ServerName example.com ServerAlias *.example.com </VirtualHost> I tried all possible solutions but they didn't work. Finally I used amazon Route-53 to setup a wildcard DNS to redirect all *.example.com to example.com. My question is, Is it okay if I use Route-53 instead of httpd.conf file for wildcard Sub-Domain ? Is there an error in my httpd.conf file ? (Note: I used the same httpd.conf settings with another hosting provider and it worked perfectly there.) Additional Information : VirtualHost configuration: wildcard NameVirtualHosts and _default_ servers: *:80 is a NameVirtualHost default server example.com (/etc/apache2/httpd.conf:1) port 80 namevhost example.com (/etc/apache2/httpd.conf:1) port 80 namevhost ip-xx-xxx-xx-xxx.ec2.internal (/etc/apache2/sites-enabled/000-default:1) Syntax OK

• Restart Fibre channel controller after blade bootup IBM HS bladecentre

  - by Spence

  I have a remote system that needs to resume on startup. If the system is simply powered on then the blades boot before the SAN is online and then the only thing you can do is restart the systems. Is it possible to restart the fibre channel controller? That way I could have a system restart the controller after boot, connect to the SAN and then restart all servers requiring SAN information? Please note that I'm not a sys admin, just shooting for ideas to get a clean startup to work, apologies if my terminology is wrong.

• FTPS SSH Host Key after IP Address Change

  - by David George

  I have a Secure FTP (FTPS) server that my remote sites to upload files to daily via scripted routines that run. I have had issues in the past when upgrading hardware and deploying new servers causing the RSA Fingerprint to change for that server. Then all my remote sites can't connect until I have the old key removed (usually via ssh_keygen -r myserver.com). I now have to change the IP address for myserver.com and I wondered if there is anyway to proactively generate new host keys so that when the server address changes all my FTPS client remote sites don't break?

• Why does RDP Licensing is licensing the same device multiple times? [closed]

  - by NeerPatel

  Possible Duplicate: Can you help me with my software licensing issue? I've got a Citrix XenApp 6.5 Farm running on Win 2008 R2 Servers. I purchased 300 Device RDP/Remote App Licenses for ~200 users. We went with Device licenses, because most of the end users use the same machines. After 1 month of operating, we started to run out of licenses. It turns out the licensing service is consuming multiple licenses for the same machine. I can revoke licenses, but there is a limit to how many I can do. Is this operating correctly? The only explanation I can come up with is that the Licensing service is giving a license to a device for every server it connects to in our Citrix farm.

• Colocation near EC2

  - by brianreavis

  Does anyone know any colocation providers near the Amazon's US EC2 facility(ies)? I'm needing to colocate a couple servers that need to be able to connect with EC2 with the lowest latency possible. I can't even find where their facilities are... Any ideas of the best solution or places to start looking? (ps. I'm well aware that EC2 instances can be configured to do pretty much anything. I have a special need that can't be deployed to EC2.)

• Welcome files are not loaded! Need help with Railo, mappings and J2EE configuration!

  - by mrt181

  I have installed a J2EE Server (tried it with Glassfish3, Tomcat6 and Resin4) on Win7 64bit and deployed Railo3.1. I have then added a virtual host to the J2EE server, i.e. Resin: <host host-name="railo"> C:/resin/webapps/railo In the Railo Admin i have added this mapping: Virtual Physical / C:/webapps/ When i access http://railo:8080/ my index.cfm welcome file in C:/webapps/ is loaded (index.cfm is definded in Railos web.xml). When i try to access http://railo:8080/test which contains the same index.cfm i get an 500 Servlet Exception java.io.FileNotFoundException: C:\webapps\test (access denied) (on all J2EE Servers i tried so far). http://railo:8080/test/index.cfm works fine. I already tried to add index.cfm to Resins welcome-file-list in app-default.xml to no avail. I want to be able to access deployed apps without this url: http://localhost:8080/app/ Instead i want to use this: http://app:8080/

• How to handle external and internal DNS on windows 2012

  - by ThePopcorn

  I'm trying to setup an Active Directory network on Server 2012 R2, and want AD's DNS to only be used internally (Ex: domain-controller.company.com) as well as some records that need both internal and external accessibility (Ex: mail.company.com) that use internal IP's on the internal network and finally some records that only need external access. The only solutions i have been able to think of, or look up are to either use a sub domain that handles all internal records, and use the plain company.com domain for all external records. These both seem to mean i have to manage two DNS servers separately. Is either of these the best ways or am i messing up somewhere?

• OSSIM - Snort/OSSEC/Nagios Logging Config Question

  - by Eric

  Quick n00b OSSIM question. I've looked around but haven't found exactly what I'm looking for. I currently have a Nagios, OSSEC, Nessus, and Snort server and I want to keep those servers active but just ship the logs to the OSSIM server and have it do the correlating and graphing. Can that be done? Everything I've seen is putting the various software functions actually on the OSSIM box but I don't want to do that. I'm running CentOS on all of the systems. Thanks.

• Win7-Server2008 RDP connection hangs on "Securing Remote Connection" for 20-30 seconds

  - by JohannesH

  I have a problem that googling has turned up nothing, except this question on experts exchange which I borrowed most of the text from. :) When I connect via Remote Desktop to a new Windows 2008 R2 server it takes 20-30s to get past the "Securing Remote Connection" message during the login. If the password is wrong, it does this every time you attempt a login (ie its not a one time thing). However, after a successful login attempt the following logins to the same server goes faster. Most servers runs on VMware here, but I don't know if that has anything to do with it.

• Linux memory fragmentation

  - by Raghu

  Hi all, Is there a way to detect memory fragmentation on linux ? This is because on some long running servers I have noticed performance degradation and only after I restart process I see better performance. I noticed it more when using linux huge page support -- are huge pages in linux more prone to fragmentation ? I have looked at /proc/buddyinfo in particular. I want to know whether there are any better ways(not just CLI commands per se, any program or theoretical background would do) to look at it.

• "Breadcrumbs" for series of hostnames?

  - by Hamy

  Does anyone know of a shell that would show a series of breadcrumbs as I navigate into/out of various servers, like this: Home > Build Machine > Vagrant > Docker-base Hopefully it could auto-detect logging in and out of various boxes and display the hostnames. Perhaps with a simple "no circular links", one could just try and monitor the hostname, but I don't know if there is a shell that can easily act as a 'parent' to the other shells on these various systems so that it can query hostname and/or other item. Any thoughts?

• Stop single NLB node at command line

  - by Patrik Hägne

  We have a NLB cluster set up for our public web servers. I'm trying to stop the "localhost" in the cluster from the command line using NLB.EXE. When I write "nbl stop" it seems that all nodes are stopped but I only want the local node (the server I'm running the command prompt on) to be stopped in the cluster. When I try specifying the node using the command "nlb stop 192.168.182.104:HOSTNAME" it fails, saying "Did not receive response from the cluster". Am I not specifying the cluster and the host correctly?

• Problem closing MDI child window in Terminal Services/Remote Desktop Connection 7.0

  - by Justin Love

  I have one user whose computer just got updated to the 7.0 Remote Desktop Connection. Concurrently, she has started having a problem closing the MDI child windows in an old FoxPro application running on the remote server. We have two different servers, both 2003, running the same application, one locally and one at a remote office. Only the remote office server is giving trouble. It works fine for me, even when logging into her TS account. No other users have complained. The other day the same user experienced an error message (path not found for a path showing a localization placeholder) starting the RDC, fixed by reboot. I suspect she may have had RDC running during the 7.0 upgrade.

• Windows 2008R2 blocks outbound LDAP for non-admins?

  - by Jon Bailey

  I've got a Windows 2008R2 terminal server with ~30 users on it. It's joined to a Samba-based domain. During the login script, we connect directly to the LDAP server to pull out certain profile information. This used to work just fine. Now, it doesn't, but only for non-local-admin accounts. Local admins work fine. As a non-local-admin: Connection to ports 389 or 636 just terminate (wireshark on the LDAP server reveals no connection attempt) Connection to other ports on the same server work fine Same thing on multiple LDAP servers Windows firewall is disabled Can't find any other rules/policies that may block this I suspect since this used to work, it came down during an update, but for the life of me, I can't find what. EDIT: I just ran Wireshark on the machine and didn't see anything when connecting to the LDAP server in question (or any LDAP server for that matter). I can, however, see traffic when I connect to that server on another port.

• cpanel api fileman alternative

  - by Coombesy

  trying to remotely unpack a zip file, then move the contents on cpanel servers. Some research led me to xmlApi class and the fileman module. And here my problem lies as Fileman module is returning html based on the cpanel theme (which we won't know) - and all I need is a list of files. here is the code flow: * using ftp, the zip is uploaded * using Fileman module unpack zip * loop through unpacked files and move here is my call to list the files: $files_html = $xml->api1_query($user, "Fileman", "listfiles", array( "{$ftp_dir}", //source dir 0 //chooser )); and it is returning the html for the filemanager - which is going to be different based on the cpanel theme. Surely their has to be another way to simply just list the files in that directory? any help would be appreciated, been researching this for past day and can't find solution anywhere. cheers ;)

• Apache mpm-itk Performance

  - by Matt Beckman

  I manage a bunch of VPSs with memory ranging from 1GB to 8GB. Most of these websites are Joomla websites, and the servers must support multiple sites/users/S-FTP. I use mpm-itk almost exclusively (mostly due to it's convenience in these shared environments). However, I'm aware it isn't known for performance, so I need some advice on making it faster. Due to the lack of documentation when I first went the way of mpm-itk, I included only one setting in the config, and that was to limit each user to 50 clients (the rest I left up to defaults): <IfModule mpm_itk_module> MaxClientsVHost 50 </IfModule> Are there any better alternatives available? Are there any settings supported in mpm-prefork or mpm-worker that are also supported in mpm-itk? Thanks!

• How is the "change password at next logon" requirement supposed to work with RDP using Network Level Authentication?

  - by NReilingh

  We have a Windows server (2008 R2) with the "Remote Desktop Services" feature installed and no Active Directory domain. Remote desktop is set up to "Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)". This means that before the remote screen is displayed, the connection is authenticated in a "Windows Security: Enter your credentials" window. The only two role services installed on this server is the RD Session Host and Licensing. When the "User must change password at next logon" checkbox is selected in the properties for a local user on this server, the following displays on a client computer after attempting to connect using the credentials that were last valid: On some other servers using RDP for admin access (but without the Remote Desktop Services role installed), the behavior is different -- the session begins and the user is given a change password prompt on the remote screen. What do I need to do to replicate this behavior on the Remote Desktop Services server?

• ForwardAgent in Jenkins

  - by r_2

  I'm trying to enable ForwardAgent in the "Publish over SSH" Jenkins Plugin. This would allow jenkins to execute deployments, rsyncs and svn+ssh checkouts on remote servers. But there's no option for this in the GUI. ForwardAgent is set to yes in /etc/ssh/ssh_config and in /var/lib/jenkins/.ssh/config, but when Jenkins jobs login over ssh, the remote session does not have the key loaded in agent. ("Could not open a connection to your authentication agent.") Is there a way to force ForwardAgent, or a better way to do this (via a Jenkins slave)? Thanks for any ideas, much appreciated!

• How to enable key forwarding with ssh-agent?

  - by Lamnk

  I've used the ssh-agent from oh-my-zsh to manage my SSH key. So far, so good, i only have to type the passphrase for my private key once when I start my shell and public key authentication works great. The problem is however that key forwarding doesn't work. There are 2 servers A & B which I can use public key to login. When I ssh into A then from there ssh into B, I must provide my password, which should not be the case. A is a CentOS 5.6 box, B is an Ubuntu 11.04 box. I have this on my local .ssh/config: Host * ForwardAgent yes OpenSSH on A is standard openssh 4.3 package provided by CentOS. I also enable ForwardAgent for ssh client on A, but forwarding still doesn't work.

• IIS: redirect to a webpage if authentication fails

  - by DrStalker

  We have an IIS site (MOSS 2007) that uses Windows Authentication. When a user that has forgotten their password tries to login the servers keeps sending 401 requests. This means on IE the user gets three prompts before IE displays a blank page, on Firefox the user is prompted over and over until they give up. We would like to change the behavior so if a user fails to login three times in a row we send them a redirect to a different site, instead of another 401 Forms authentication is not an option; the site has to remain on windows authentication to allow for SSO capabilities and certain sharepoint functions. Is there any way to tweak the IIS behavior to do this?
