• How to create a WHM/cPanel account, without creating a new sub-domain?

  - by Cyclops

  I have a basic VPS (full root access), with WHM/cPanel, and am learning the ropes. I'm trying to create a new account for an existing domain (mysite.com), and so far WHM won't let me - it either wants a sub-domain or fake domain, but won't allow two accounts for one domain. In the beginning, there was only the root account, and it wouldn't let me login to cPanel - a quick chat with tech support, and I am informed that I need to create a second account, which I did. So now I have an account, call it ns1me, for domain mysite.com. Now I want to create a django account. I go through the same process, but WHM won't allow me to use mysite.com as the domain for django. The docs recommend a sub-domain, so I fill the box in with django.mysite.com. I then realize that has actually created a sub-domain - going to django.mysite.com shows me its home directory, along with helpful information about what version of Apache, Python, and other mods its running (thanks, Apache). I really don't want a sub-domain, so that's out. Another chat with tech support, and they recommend a fake domain name, as it won't create anything. Sure enough, using a domain of djangomysite.com works, and WHM allows me to create a django account. But of course, I can't send email to [email protected] (where I could to [email protected]). What I want, is to be able to create a second account, associated with mysite.com (so I can run cPanel logged in as django, send email to [email protected], etc) - without creating a whole new sub-domain, or fake domain.

• Does Xenapp require Windows Terminal Services (Remote Desktop) licenses?

  - by John Virgolino

  We have a Xenapp 5.x server running for over a year now. It does not have any purchased Terminal Services (Remote Desktop) licenses installed. It is running on a Windows 2008 Server box. I am aware that Terminal Services runs fine for about 3 months and then supposedly stops issuing licenses. On occasion, Xenapp stops working and we see lots of License errors in the event log, although not necessarily every time. In most cases, a reboot or 2 resolves the problem. We figured it was because of the lack of TS licenses. I spoke with Citrix and they said we had to have the licenses, but it begs the question that if we have to have the licenses, how does it work the majority of the time without them!!?? I have not received a straight answer yet and before I tell my client to shell out more money, I need to understand the technical reasoning for how this is actually working if we are breaking the rules here. We will buy the licenses if necessary, but there has to be an explanation for this. I am hoping the community can help where Citrix apparently cannot. Thanks much!

• where are the default ulimit values set? (linux, centos)

  - by nomercysir

  I have two CentOS (5) servers with nearly identical specs. When I login and do: ulimit -u on one machine, I get unlimited and on the other, 77824 When I run a cron like * * * * * ulimit -u > ulimit.txt I get the same results (unlimited, 77824). I am trying to determine where these are set so that I can alter them. They are not set in any of my profiles (.bashrc, /etc/profile, etc .. these wouldn't affect cron anyway) nor in /etc/security/limits.conf (which is empty). I have scoured google and even gone so far as to do grep -Ir 77824 / but nothing has turned up so far. I don't understand how these machines could have come preset with different limits. I am actually wondering not for these machines, but for a different (CentOS 6) machine which has a limit of 1024, which is far too small. I need to run cron jobs with a higher limit and the only way I know how to set that is in the cron job itself. That's ok, but I'd rather set it system wide so it's not as hacky. Thanks for any help. This seems like it should be easy (NOT) EDIT -- SOLVED Ok, I figured this out. It seems to be an issue either with CentOS 6 or perhaps my machine configuration. On the CentOS 5 configuration, I can set in /etc/security/limits.conf: * - nproc unlimited and that would effectively update the accounts and cron limits. However, this does not work in my CentOS 6 box. Instead, I must do: myname1 - nproc unlimited myname2 - nproc unlimited ... And things work as expected. Maybe the UID specification works to, but the wildcard (*) definitely DOES NOT here. Oddly, wildcards DO work for the 'nofile' limit. I still would love to know where the default values are actually coming from, because by default, this file is empty and I couldn't see why I had different defaults for the two CentOS boxes, which had identical hardware and were from the same provider.

• Users Password does not reset after successful login at the console but works fine with SSH

  - by jnbbender

  The title says it all. I have my unsuccessful login attempts set to three. I purposefully fail logging in 2x, then when I SSH into the box successfully the 3rd time my count drops back to zero; exactly what should happen. But at the console I get failed login attempts EVEN for my successful login attempts. I am using RHEL 5.6 and no I am not able to upgrade. Here is my system-auth file: auth required pam_env.so auth required pam_tally.so onerr=fail deny=3 per_user auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth required pam_deny.so account required pam_unix.so account required pam_tally.so account sufficient pam_succeed_if.so uid < 500 quiet account required pam_permit.so password requisite pam_cracklib.so try_first_pass retry=3 password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok password required pam_deny.so session optional pam_keyinit.co revoke session required pam_limits.so session [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid session required pam_unix.so I have tried adding reset after and in place of per_user in the auth required pam_tally.so field. Nothing seems to work and I don't know why SSH is working just fine. Any ideas?

• Two folders with identical names causing many problems.

  - by R. A. Chaucer

  In my 'Documents' folder (Win7) I have two folders with names that appear in Explorer to be identical, though their contents are different. I can rename them both to something else (eg: 'Test') and Explorer doesn't complain. The dir listing that cmd.exe and powershell gives me only lists one of them, but also lists this suspicious entry: 20/04/2010 12:16 PM <DIR> ???? Even if I rename the folders to have unique names, one of them still shows up as ???? in cmd.exe. Desktop.ini in my Documents folder doesn't contain anything out of the ordinary. Both folders appear to be read-only in their properties panel, and if I untick the read-only box it will ask me if I want to apply the action recursively, but either way when I close the panel and open it again the folder is once again read-only. They are both set to not inherit permissions. The folder that shows up correctly in the cmd.exe dir listing is the "real" one, the other seems to be automatically created when a program tries to access it. How is this possible?This is driving me nuts!

• Debian - Problems Unmounting External Hard Drives

  - by user331981

  I recently installed Debian Testing on a new laptop and I just noticed that I am having some issues with unmounting external hard drives. I am using Mate Desktop 1.8.1. With the 1st drive, if I right click on the drive and select “safely remove”: The drive unmounts, spins down, immediately spins back up an remounts. Unable to unmount. With the 2nd drive, if I right click on the drive and select “safely remove”: The drive unmounts but does not spin down. With the 3rd drive, if I right click on the drive and select “safely remove”: The drive unmounts but does not spin down, immediately spins back up but does not remount, and after 20 seconds, it spins down and stays that way. Behavior is the same on both USB 2.0 and USB 3.0 ports. On my last laptop, on which I also used Debian Testing + Mate desktop, the safe removal of drives worked out of the box and I never had an issue with it. The drives would unmount, spin down and stay that way. To remount the drive, one needed to unplug the device and plug it back in. I am unsure how to troubleshoot this issue and I am not sure if it is merely a matter of installing a “missing” package of editing a config file. Thank you in advance.

• Exchange 2003 inbound routing issue

  - by user565712

  Just recently we started experiencing inbound routing issues. Email adddressed to [email protected] is intermittantly translated to [email protected]. This is happening for several users and, as stated, is intermittant. I don't know where to start looking for the solution. Is this an Exchange issue? A DNS issue? We have a single Exchange server inside our network with an FQDN of server.domain.local with a single SMTP Virtual Server. The Advanced properties of the Delivery tab of the Virt Server has an empty Masquerade Domain textbox and the value for the FDQN text-box is set to the domain itself, domain.com. The DNS record for domain.com is a CNAME entry referencing www.domain.com. Is this somehow related to the problem? I checked the headers of the inbound messages that generated NDRs as a result of being sent to [email protected] and nowhere in the header is www.domain.com mentioned. To make my life even more difficult, we use Postini as a third-party SPAM filtering service. Our MX records point to the Postini servers and Postini delivers the messages to our server. Perhaps it is Postini that is mucking things up? sigh I'm having trouble with this one and the intermittent aspect is making it that much more difficult for me. Any ideas?

• cheap gigabit switch for small business

  - by neoice

  my friend's business is currently borrowing my Adtran 1224R and is very happy with it. it's configured with a few VLANs to segment customers, internal traffic and public wifi. port 1 is a "trunk" port to the router, a chunky Linux box with iptables+NAT. they push a lot of traffic over the LAN (data backups) and really need gigabit. besides, I'd like my Adtran back :P my goal is to find a cheap(ish) switch that can function as a drop-in replacement. it looks like VLAN trunking is actually part of the 802.1q spec, so anything with VLAN support should cover the current trunk-to-router setup. it's nice to have both a web interface and SSH, but I can configure it either way if needed. things like the Netgear GS724T have caught my eye, but it seems like none of the hardware in the $300-500 range have really solid reviews. I'm concerned that "cheaper" hardware might not work for a network full of power users. does anyone have a recommendation for the Netgear GS724T or a switch that will meet my needs?

• Does cloud computing offer this? [closed]

  - by TheBlackBenzKid

  I have some newb questions I want answering please about cloud hosting - we are currently looking at Rackspace and getting a windows box. This is the situation: We have 15 computers in our office. We have 3 printers, some wifi and some network plugged. We have a standard router and the office share things via dropbox. The computers are not on Windows SBS or something similar. We want a cloud hosting solution that will offer User can login on any machine in the office and see the machine software User can login on any machine in the office and open Outlook and their emails and signature will be on exchange automatically A shared company folder on the network All printers automatically installed on the network Users can login remotely to access emails via the web At the moment we have a network company saying we need Xeon server in house with backup and psu and Windows SBS with license for each machine and also we need cabinets and cabling setup and also load balancers and modification of our DNS for emails. My question is this. Can cloud offer this? Can we have a server in the cloud that does this? Is it possible I mean the computers would be wireless connected to this cloud and you turn the machine on and its hosted?

• Adding user groups from a remote domain server to permissions of a remote desktop terminal server fails. why?

  - by doveyg

  I have 3 computers, two of which are servers running Windows Server 2008 and another running Windows 7. One of the servers has the following roles installed; Active Directory, DHCP and DNS. The other server has a Terminal Server role installed. I am trying to log-on to the Terminal Server via Remote Desktop using the Windows 7 machine with credentials from the Active Directory server. Sounds simple enough, right? Well, no. Whenever I try to add users or groups from the Active Directory Domain server to the Terminal Server's permissions for RDP it seems to ignore, or forget, them. Though the various methods I was able to find it either adds a strange sting of numbers after the user group or the logo to the left has a question mark on it, reopening the dialogue box replaces the user group with the name of the Domain. I am confident I have the Domain setup correctly as I am able to log-on to users in the Active Directory from other computers I have put in the Domain, and when I attempt to browse the user objects from the Domain I am prompted with a username/password field and am able to view the structure of Active Directory objects. Please advise.

• How can one restrict network activity to only the VPN on a Mac and prevent unsecured internet activity?

  - by John

  I'm using Mac OS and connect to a VPN to hide my location and IP (I have the 'send all traffic over VPN connection' box checked in teh Network system pref), I wish to remain anonymous and do not wish to reveal my actual IP, hence the VPN. I have a prefpan called pearportVPN that automatically connects me to my VPN when I get online. The problem is, when I connect to the internet using Airport (or other means) I have a few seconds of unsecured internet connection before my Mac logs onto my VPN. Therefore its only a matter of time before I inadvertently expose my real IP address in the few seconds it takes between when I connect to the internet and when I log onto my VPN. Is there any way I can block any traffic to and from my Mac that does not go through my VPN, so that nothing can connect unless I'm logged onto my VPN? I suspect I would need to find a third party app that would block all traffic except through the Server Address, perhaps Intego Virus Barrier X6 or little snitch, but I'm afraid I'm not sure which is right or how to configure them. Any help would be much appreciated. Thanks!

• Nginx vhost configuration

  I am attempting to setup a new server with Nginx 1.0.10 on debian 6. The config below works perfectly on a server with nginx 0.8.36 on Ubuntu 10.04.3 but not on the new box.

• Questions for anyone who has used Sun Type 7 keyboards

  - by Irinotecan

  So I noticed that Oracle is still selling Sun Type 7 keyboard and mouse packages. I was thinking of buying one for a Linux box at my house so I had easy access to some of the extra keys such as Compose and Alt-GR. I have some questions though before I do for anyone who has used these -- it's been a very long time since I've used an actual Sun keyboard. They show that both a PC and UNIX layout is available. Unfortunately, I cannot find anywhere a clear picture of both layouts to determine the difference. Can anyone post pictures of the 2 different layouts for me to take a look at? I don't remember what some of the "Solaris shortcut" keys do, like Props, Front, Stop, and Again. Are these vestiges from OpenWindows? Do they have any usage on a modern Solaris like OpenSolaris running Gnome? Do they automatically map to anything useful on Linux, or am I going to have to map them myself to something with XModMap? When I last used a Sun keyboard, I remember it having a rather mushy feel to it, so I am wondering if any touch typists could weigh in on whether this keyboard "feels nice" for day to day touch typing. Thanks!

• Inexpensive (used) hardware for Xen virtualization test?

  - by Jason Antman

  Virtualization is one of the areas where I could really use some experience. I also run quite a few services (web, mail, dns, etc.) out of my home. Since most of my hardware is getting a bit old (I'm running on stuff that was surplused years ago...) I decided that it's about time I start renewing some things, and also play around with virtualization a bit more. My plan is to setup a SAN box (simple iSCSI target, relatively inexpensive gigE switch), get a pair (for starters) of new servers, and start building some new stuff with Xen, specifically planning on playing with live migration and full virtualization. Does anyone have recommendations for used, older "servers" (really anything in a rack-mount form factor, I'm not too worried about things like iLO/iLOM for the test nodes) that support VT-x/AMD-V? I'm biased to HP, but it looks like they didn't make Proliants with VT-x/Vanderpool processors until G6 (for the DL360) or so, which is way out of my price range. I'm looking in the sub-$300 range (or less, if possible), used, probably Ebay. Any recommendations are greatly appreciated. Edit:And, to catch this before the comments start coming - these are personal systems. I have first-generation Proliants still in use (I got them as corporate surplus in 05, they've been running since then, and probably were running since 01 or 02 prior to being sold). I don't need anything shiny and new - I've got a bunch of old boxes, at least one complete replacement for every model in use, and that's fine for me (and easy on the wallet).

• Easiest way to find out if user has either Windows 7 or Vista (through telephone support)?

  - by Rabarberski

  If you have to provide some initial troubleshooting support by phone [or email], and you don't have access to the PC itself, what is the easiest and most foolproof question to find out if the 'dumb' user is using either Windows 7 or Windows Vista? For example: determining if the user has either Windows XP or Windows Vista/7 is easy. Just ask the user if the button at the left bottom corner is (a) either square with the word 'Start' on it, or (b) it is a round button. But how to determine the difference between Vista and 7? Edit: For all the existing answers the user has to type something, and do it correctly. Sometimes even that is already hard for a computer illiterate user. My XP example just requires looking. If it exists (although I am afraid it doesn't), I think a solution that is just based on something this is visually different between Vista and 7 would stand above all others. (Which makes Dan's suggestion to turn over the box and look at the label" not so stupid). Perhaps the small 'show desktop' rectangle at the right side of the task bar (was that present in Vista)?

• Reasons for Ajax navigation breaking on Coldfusion/Apache when running an app in iOS fullscreen mode? [closed]

  - by frequent

  Not sure if this belongs to SO or here. I'm running a webApp using jquery, jquerymobile, requireJS and apache, coldfusion8, mysql 5.0.88 serverside. The app works fine until I try to run it in fullscreen mode on iOS (add icon to homescreen, launch app from there with <meta name="apple-mobile-web-app-capable" content="yes" /> specified). This meta tag will break the Jquery Mobile AJAX navigation. The AJAX request will fail and the requested page will be loaded as a new page, thereby restarting the app on every page change. I have chased this through the whole front end starting from requireJS through Jquery Mobiles AJAX navigation down to the AJAX request being made in Jquery. xhr.send( ( s.hasContent && s.data ) || null ); In regular browser this works no problem. In fullscreen mode, this fails (readystate=0, empty response). I have found this article, which argues that fullscreen mode is like a browser instance with different HTTP strings. On ASP.net this results in the browser not being identified by the server and only basic browser settings being assumed (e.g. no Javascript). I'm a little lost where to start looking for possible reasons serverside. I have not written any server code for handling Ajax page navigation, so this must be something that is handled out of the box by Coldfusion or Apache? Question: Where could I start looking for problable causes of fullscreen mode breaking AJAX navigation if I assume Coldfusion or Apache are the culprits? Is there a setting I'm missing in httpd.config? What else could be the problem? Thanks for inputs!

• Question marks showing in ls of directory. IO errors too.

  - by jaymoo

  Has anyone seen this before? I've got a raid 5 mounted on my server and for whatever reason it started showing this: jason@box2:/mnt/raid1/cra$ ls -alh ls: cannot access e6eacc985fea729b2d5bc74078632738: Input/output error ls: cannot access 257ad35ee0b12a714530c30dccf9210f: Input/output error total 0 drwxr-xr-x 5 root root 123 2009-08-19 16:33 . drwxr-xr-x 3 root root 16 2009-08-14 17:15 .. ?????????? ? ? ? ? ? 257ad35ee0b12a714530c30dccf9210f drwxr-xr-x 3 root root 57 2009-08-19 16:58 9c89a78e93ae6738e01136db9153361b ?????????? ? ? ? ? ? e6eacc985fea729b2d5bc74078632738 The md5 strings are actual directory names and not part of the error. The question marks are odd, and any directory with a question mark throws an io error when you attempt to use/delete/etc it. I was unable to umount the drive due to "busy". Rebooting the server "fixed" it but it was throwing some raid errors on shutdown. I have configured two raid 5 arrays and both started doing this on random files. Both are using the following config: mkfs.xfs -l size=128m -d agcount=32 mount -t xfs -o noatime,logbufs=8 Nothing too fancy, but part of an optimized config for this box. We're not partitioning the drives and that was suggested as a possible issue. Could this be the culprit?

• Allow more websocket connections

  - by Switz

  I want to load balance my node.js (DerbyJS to be specific) application on a basic Linode (512MB ram). It can probably take more than one process running at once. The querys/database does not concern me as I'm not doing anything intensive. The problem at the moment is that it can only handle up to ~40 websocket connections at once. I would love if I could get that number in the few hundred+ range. I anticipate a lot of traffic on launch due to the fact that it's a highly niche community with an engaged audience, but after it should be fine with just ~20-40 connections at once, which it handles perfectly as of now. I don't mind spending a bit of money for a week or two worth of running, but I also don't want to switch production environments. How can I test the process to see how many instances I am able to run on the box? Will increasing the number of processes increase the amount of websockets I can handle, or is that a limitation of the server's network? I have an old Macbook Pro running Linux sitting next to me that has 2GB ram and a 2.8 Dual Core Processor. Could I use this to handle some of the extra load? I could probably load balance with nginx to its IP. I'm on a FiOS home network. If you have any suggestions, I'd really appreciate it. Thanks

• MySQL has stopped accepting connections from other users than root

  - by John

  Hi there. I'm running a mysql-server a long with apache and tomcat on a Gentoo box. To administer mysql I'm using phpMyAdmin. A couple of hours ago I received a call -- a user was unable to login to phpmyadmin. I logged on to phpmyadmin with the root user, and reset the password. The user was still not able to login. I then decided to give it a go myself, and even I wasn't able to login. I tried creating several user accounts, none of them were able to access mysql via jdbc/mysql-client/phpmyadmin. The only user that seems to work is root. What's even more strange is that websites that connect to mysql with a user other than root are still able to login and retrieve content from the database (it's mainly wordpress and a tomcat webapp). I have made sure it's not just cached, I was able to post SQL queries to the database via these web apps still. However, I am unable to login to phpmyadmin/mysql-client with this user and I am also unable to set up a connection with this user for any new web-applications. Any help is immensely appreciated.

• Linux RHEL : Making disk image efficiently

  - by TheProfoundGeek

  I have a linux box having RHEL. Its disk (hda1) is having free space of about 25GB. I have an another disk (hda2) which is of 250GB having another RHEL instance, it's partitioned for 200GB. Data on the disk occupies about 21GB of data. The image of hda2 needs to be taken and restored on other disk of same specs. What is the best way to make image file of the hda2? Ideally the images size should be around 25GBs as the actual data on the disk is just 21GB. I am aware about the following two methods. Method 1 : Raw Image dd if=/dev/hda2 of=/path/to/image dd if=/path/to/image of=/dev/hda3 Question 1 : Will the above method make a gigantic image of 250GBs? Is it efficient? Method 2 : Compressed Image. dd if=/dev/hda2 | gzip > /path/to/image.gz gzip -dc /path/to/image.gz | dd of=/dev/hda2 Question 2 : I tried the method 2, its taking too long. What are the pit falls of this methods? Which of the above method id efficient and why? Is there any other Linux utility which can do the job? Third party tools are no no.

• NFS server hangs after 3 minutes

  - by John P

  I have a VPS running Centos 6.3 with a fully updated NFS. When I mount the NFS directory from the client, everything works perfectly fine for approximately 3 minutes, then the client hangs attempting to see the directory. nfs-utils-1.2.3-26.el6.x86_64 service nfs status rpc.svcgssd is stopped rpc.mountd (pid 2544) is running... nfsd (pid 2609 2608 2607 2606 2605 2604 2603 2602) is running... rpc.rquotad (pid 2540) is running... cat /etc/exports /home/user XX.XX.XX.20(rw,async,no_root_squash) The client is running Centos 5.8. The directory is mounted using mount x.x.x.6:/home/user /mnt When everything is working, I get the following on the client: /usr/sbin/rpcinfo -p X.X.X.6 | grep mountd 100005 1 udp 892 mountd 100005 1 tcp 892 mountd 100005 2 udp 892 mountd 100005 2 tcp 892 mountd 100005 3 udp 892 mountd 100005 3 tcp 892 mountd When it stops working, rpcinfo just hangs on the client, however running the above command on the server does return data. There are no logs on the NFS Server side that would indicate an issue. On the client side, I see: cat /var/log/messages kernel: nfs: server X.X.X.6 not responding, still trying The client and server are plugged into the same switch, however they are on different networks. The server is a VPS while the client is a dedicated box. SELINUX is in permissive mode on both client and server, and I've turned iptables off on the server to make sure that was not causing an issue. Any ideas would be helpful - right now I'm having to restart NFS every two minutes in a cron job to keep it semi working. Thanks

• TGT validation fails, but only for one user

  - by wzzrd

  I'm seeing the weirdest thing here. I have a couple of RHEL3, 4 and 5 machines that validate user credentials through Kerberos with an Active Directoy domain controller as their KDC. This works for all of my users, save one. There is one account that is unable to log into RHEL3 Linux machines and generates the following errors there: May 31 13:53:19 mybox sshd(pam_unix)[7186]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=10.0.0.1 user=user May 31 13:53:20 mybox sshd[7186]: pam_krb5: TGT verification failed for `user' May 31 13:53:20 mybox sshd[7186]: pam_krb5: authentication fails for `user' Other accounts, like my own, are fine: May 31 17:25:30 mybox sshd(pam_unix)[12913]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=10.0.0.1 user=myuser May 31 17:25:31 mybox sshd[12913]: pam_krb5: TGT for myuser successfully verified May 31 17:25:31 mybox sshd[12913]: pam_krb5: authentication succeeds for `myuser' May 31 17:25:31 mybox sshd(pam_unix)[12915]: session opened for user myuser by (uid=0) As you can see, TGT validation fails. This only happens for this specific account, not for any other. The failing useraccount's password has been reset, I inspected both user objects in Active Directory, but I see nothing out of the ordinary. If I have the failing useraccount log into a RHEL4 or 5 box, there is not problem, so it must be RHEL3 specific, but the fact that only one account suffers from this, alludes me. Maybe someone has seen this before?

• PPTP VPN on Server 2008 Enterprise

  - by Mike K

  I asked this question on Server fault and was told that was not allowed so im moving it here. I am running Windows Server 2008 enterprise in my HOME network inside of vmware workstation. I am running this on my home network to setup a PPTP VPN connection at home. I have correctly setup everything I needed to make it work, including opening all the ports, 1723 and 43 (GRE). I am able to connect just fine, but when I connect I dont have internet unless I uncheck use remote gateway. The thing is, I want to use the remote gateway to route all my traffic through that connection. Can someone tell me why this isnt working and how to get it to work. When I have remote gateway checked, and I do an ipconfig I dont get a remote gateway for the VPN connection, its 0.0.0.0 when id assume if connected properly should be 192.168.1.254 (my ATT Home Router). Also, if I cant get the remote gateway issue to work, and I have to uncheck that box to get internet, does this mean my VPN session is no longer encrypted? I am fully aware the PPTP VPN is the weakest VPN encryption out there but still having that extra layer of security when im on an unsecure wifi connection makes me feel a bit better. Thank you for all your help in advance. Someone told me I need to setup a gateway or router configured on the server. If thats the case, how go I go about telling the remote co

• Windows scroll without focus

  - by DanielCardin

  So I have a windows 8 laptop at home, and a windows 7 laptop at work. Both have synaptics touchpads. The problem is that on the work laptop, I can scroll any window regardless of which one is currently focused. That is the behavior that I want on both computers. This does not currently happen on the windows 8 computer. I know I can use (and have tried!) wizmouse, alwaysmousewheel, katmouse, etc; but none of them work 100% like the work computer. katmouse sometimes stops working, alwaysmousewheel, ive had problems with it scrolling on its own, wizmouse sometimes makes the mouse lag. Others have just not worked. Before I got the work computer, I had resigned myself to it, but now I see that it works, out of the box without using any external programs, on an older operating system, and wonder why I cant get it to work the same way on my own computer! All my searches have just been people suggesting the external programs that ive already tried, so answers suggesting those aren't really what I'm looking for (unless its some magic I can do with the synaptics driver, which by the way is more up to date on the windows 8 computer that is doesnt work on).

• Private subnet for VM server host-only network

  - by Derek Pressnall

  At my current job, we distribute a product based on a Linux server with multiple VMs defined (using KVM / libvirt). We are planning to expose limited ports to the customer's network, and use iptables to direct inbound traffic to the appropriate internal VM. My question: is there a class of private subnets that I can use for the internal host-only network that is least likely to conflict with a client IP subnet? Specifically, if I choose a /24 out of any of the RFC-1918 defined private subnets (such as 192.168.x.x), there is a chance of conflicting with a customer-used range. I noticed that several current VM implementations default to 192.168.122.x -- is this due to an RFC that I'm not familiar with, and therefore this is a safe range to use (that most network admins would avoid)? Or did the various VM vendors just pick that range randomly? I guess I'm looking for an IP range that is more private than the existing private (RFC1918) addresses. The only other thought I had was to use one of the "Test Net" IP ranges reserved for documentation purposes (RFC 5737). Note, that I'm not worried about a customer's network blocking these IPs, as this is only internal to our server (packets get NATted before leaving the box). However this does seem more unorthodox than just sticking with the default 192.168.122.x/24 subnet.
