• How to get a higher resolution on Ubuntu 11.04 using an intel chipset

  - by Saif Bechan

  I have a bit slow PC here, so I decided to put Ubuntu 11.04 on it. It use to run Windows Vista on a resolution of 1280x1024, so both my hardware and monitor support it. Now I'm on Ubuntu, but can only run 1024x768, and the screen is not that bright. Its like when you don't have the right drivers on a Windows machine. Now i'm new to linux, so I do not know what do do. I have an onboard Intel chipset i965. Maybe this is some useful information, I read something about it on a forum: lspci 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02) 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) 00:1c.0 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 1 (rev 01) 00:1c.1 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 2 (rev 01) 00:1d.0 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation N10/ICH 7 Family USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 01) 00:1f.2 IDE interface: Intel Corporation N10/ICH7 Family SATA IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation N10/ICH 7 Family SMBus Controller (rev 01) 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• Which server software and configuration to retrieve from multiple POP servers, routing by address to correct user

  - by rolinger

  I am setting up a small email server on a Debian machine, which needs to pick up mail from a variety of POP servers and figure out who to send it to from the address, but I'm not clear what software will do what I need, although it seems like a very simple question! For example, I have 2 users, Alice and Bob. Any email to [email protected] ([email protected] etc) should go to Alice, all other mail to domain.example.com should go to Bob. Any email to [email protected] should go to Bob, and [email protected] should go to Alice Anything to *@bobs.place.com should go to Bob And so on... The idea is to pull together a load of mail addresses that have built up over the years and present them all as a single mailbox for Bob and another one for Alice. I'm expecting something like Postfix + Dovecot + Amavis + Spamassassin + Squirrelmail to fit the bill, but I'm not sure where the above comes in, can Postfix deal with it as a set of defined regular expressions, or is it a job for Amavis, or something else entirely? Do I need fetchmail in this mix, or is its role now included in one of the other components above. I think of it as content-filtering, but everything I read about content-filtering is focussed on detecting spam rather than routing email.

• My desktop has started overheating -- how hot is hot?

  - by Jerry

  I have a two year old desktop, some random quad core HP desktop. It used to run very quietly, but in the past month, the fans start up anytime anything "serious" is being done -- compiles, playing video, etc. Right now, speedfan and speccy report the cores are between 50C and 70C. Speedfan reports this as hot. (Nice flame icon.) Well, the system does sit on my carpet, so two weeks ago, I took off the lid, and cough *cough* it was pretty filled with dust. I got out an air can, turned on a vacuum and carefully got out all the dust that I saw on the CPU fan the case fans any fan I saw (graphics board) and blew out all the dust I could from all the circuit boards. And then I closed the case back up. It has definitely run cooler since then, but it still runs hot, and I hear high speed fan noise I never heard before. How hot is too hot? At what temps do consumer grade CPUs die? What should I be looking to do? Replace CPU fan? (It seems to work) Replace power supply fan? Assuming the dust problem is gone, where should I be looking to determine why the machine is heating up? Epilogue: After following the various pieces of advice given here, the system did run cooler, but it was still noticeably running louder (hotter) than just a few months prior. I ended up purchasing a new cpu heatsink and fan and during installation found the cooling grease from the original heatsink was just a dried, cracked layer, probably more of an insulator than heat transfer agent. With the new fan AND the new heatsink compound, the system ran much much cooler and the fan rarely turns on.

• "Path Not Found" when attempting to write to a sub folder within a mapped drive

  - by Adam

  We have an interesting issue with one of our server shares, or possibly, our Win 7 desktops. When our users try to save files in a sub folder, either via copy/paste or through an application, to a mapped drive on our DC they receive an error saying "Path not found". They can however browse this folder and open files from it. This is where the "Path Not Found" error doesn't seem to stack up in my opinion. Users can however save files fine in the root folder of the mapped drive, it appears only to affect sub folders. It seems to be random which users and machines this affects. The users can log on to a different machine and be able to save in sub folders fine, on the same mapped drive. Event viewer hasn't been much help either. Currently, the only solution we have found is to image the machines affected which solves the issue. Our servers are Server 2008 R2 with Win 7 Pro desktops. Any help/pointers/suggestions would greatly be appreciated.

• How to configure VirtualBox server for performance at home

  - by BluJai

  I currently have two physical Ubuntu Server 10.10 servers at home: one serves as our firewall/router/DHCP/VPN server and the other performs double-duty as a file server and a VirtualBox host for an Ubuntu Desktop 10.10 machine which I use from remote connections (via NoMachine) for many thin-client purposes which are irrelevant to my question. What I'd like to accomplish is to consolidate the two physical machines into one which is a dedicated VirtualBox host (most likely running Ubuntu Server 10.10). Note that I'd like to stick with VirtualBox (if possible) because I'm most comfortable with it and use it on a daily basis at both home and work. Specifically, I plan to have one VM set up as file server, another as the firewall/router/DHCP/VPN (or possibly split those a bit) and a third, which is the only current VM (already VirtualBox), which is the thin-client host. My question comes down to performance and/or recommendations about the file server VM. The file server hosts about 6 terabytes of data across 4 drives. What I'd like to do is use raw disk access from the VM directly to the existing disks. However, I'm curious what performance advantage/disadvantage that would have as compared to using shared folders from the VM host and basically just have the whole drive served as a shared folder to the VM which would then serve it to the other machines on the network. I don't know if virtual disks would even work in this scenario and I certainly wouldn't want a drive to be filled with just a single file which is 1.5 TB (disk image). To add understanding of context, but not to get additional advice, I want to virtualize these machines because I intend to regularly use the snapshot capabilities of VirtualBox for the system disks (which will be virtual drives) of the VMs and I have some physical space/power needs to address (as I mentioned, this is at home).

• SORT empties my file?

  - by Jonathan Sampson

  I'm attempting to sort a csv on my machine, but I seem to be erasing the contents each time I use the sort command. I've basically created a copy of my csv lacking the first row: sed '1d' original.csv > newcopy.csv To confirm that my new copy exists lacking the first row I can check with head: head 1 newcopy.csv Sure enough, it finds my file and shows me the original second now (now first row). My csv consists of numerous values seperated by commas: Jonathan Sampson,,,,[email protected],,,GA,United States,, Jane Doe,Mrs,,,[email protected],,,FL,United States,32501, As indicated above, some fields are empty. I want to sort based upon the email address field, which is either 4, or 5 - depending on whether the sort command uses a zero-based index. So I'm trying the following: sort -t, +4 -5 newcopy.csv > newcopy.csv So I'm using -t, to indicate that my fields are terminated by the comma, rather than a space. I'm not sure if +4 -5 actually sorts on the email field or not - I could use some help here. And then newcopy.csv > newcopy.csv to overwrite the original file with new sort results. After I do this, if I try to read in the first line: head 1 newcopy.csv I get the following error: head: cannot open `1' for reading: No such file or directory == newcopy.csv <== Sure enough, if I check my directory the file is now empty, and 0 bytes.

• How do I configure nVidia drivers on a Portable Ubuntu setup?

  - by Nicholas Flynt

  I've been pulling my hair out over this one for a couple of days now, google is no help. I've created a wonderful (until this issue) portable copy of Ubuntu linux that will boot on mostly anything by using a USB enclosure for my laptop's 80GB SATA drive. So far so good, it boots and runs on everything, and on non-nVidia card setups was even detecting the drivers, or letting me install the required drivers for hardware acceleration and compiz. Because you know, the wobble windows are the most awesome thing ever. Anyway, my desktop machine had an nVidia card, so I'm thinking, sure, I'll just install the nVidia drivers like before and everything will work happily. Not so-- now the desktop and any other nVidia cards work great, but it seems to have completely disabled any other graphics cards. When the kernel module detects that an nVidia card isn't present, it shoots up this nasty little dialog box giving me the option to boot into "low graphics" mode, which doesn't even allow me to use the correct screen resolution, much less see the installed graphics card and try to configure a driver for it. Is there any way to configure Ubuntu (with the dreaded nVidia kernel module) so that it can use nVidia's drivers when an nVidia card is present, and default to the normal (not low-graphics) setup in other cases, so that it has a fair chance of using what's actually present? I'm not afraid to much with config files, I just don't know the underlying system well enough to feel comfortable diving in without a push in the right direction. Thanks guys!

• Windows 7 Blank Screen on Boot / Login

  - by Greg

  I have a new system that's having a few problems... sometimes (seems to be when the PC is cold, i.e. has been switched off for a while, though that could be my imagination) I get a blank blue screen when I boot up. The system boots normally and auto-logs-in. The desktop loads and I'm even able to launch applications, but then everything disappears and the screen goes to the default windows desktop blue colour (not the desktop image, just a plain blue with no mouse cursor). At this point the machine completely locks up - I'm unable to even toggle Num Lock and have to hold in the power button for 5 seconds to kill it. Interestingly if I manage to launch some applications before it goes blank, they will usually crash... sometimes explorer.exe will crash too. When I reboot, the system is fine and stable. I've installed the latest graphics drivers and run memtest86+ for 6 passes (and counting) with no errors. The system specs are: CPU: Intel I7 2.66 @ 3.4GHz RAM: 6GB (3 * 2GB DDR3) HDD: 128GB Crucial M225 SSD Motherboard: Gigabyte EX58-UD3R Gfx: ATI Radeon Sapphire 5870 1GB Note: There are a few similar questions but I haven't found one that matches my symptoms

• VPN Error 691 but server says authenticated on server

  - by Andy

  Hello all, I have a problem with a vpn connection on Windows XP SP3 that appears to be related to an account (maybe privilleges or an option that I have missed). When connecting using my account, which is a domain administrator account it will connect to through the vpn fine. However, using an account created for another person they receive Error 691: Username or Password is not valid for this domain. On the domain controller (windows 2003) I see a logon successful message: User DOMAIN\user was granted access. Fully-Qualified-User-Name = int.company.net.au/People/Management/User NAS-IP-Address = 10.30.0.3 NAS-Identifier = not present Client-Friendly-Name = MelbourneCore Client-IP-Address = Router-ip Calling-Station-Identifier = not present NAS-Port-Type = Virtual NAS-Port = 77 Proxy-Policy-Name = Use Windows authentication for all users Authentication-Provider = Windows Authentication-Server = undetermined Policy-Name = Remote VPN Access Authentication-Type = MS-CHAPv1 EAP-Type = Does anyone have any ideas as to where else I should look for finding a solution? If i use the wrong password it gives a logon failure error in the event viewer. Also removing them from the remote access group gives a logon failure error. Nothing appears in the event viewer on the local machine. In the past all that is required is to add them into our Remote Access Users group. Any help?

• How is Apache still working?

  - by PJ

  Recently, I decided to set up a local development environment for my work projects. I'm a PHP developer, with just enough knowledge of Linux and Apache to break things mightily. To get the local environment looking like my work environment, I had to upgrade PHP. When I did, Apache wouldn't restart. I decided I wanted to start fresh (this is where things went wrong) and that I'd reinstall Apache and PHP using MacPorts. So, I went through and tried to delete all the Apache files. Yup. I ran locate apache2 and deleted any folders that looked important. (I know, I know) Then I did a /usr/libexec/locate.updatedb to make sure everything was up to date. I even restarted my machine, just to make sure. The issue is, http://localhost still works. As does an alias I set up, http://butler. Shouldn't they not work? Now that I'm this far in, are there any tips for how to completely remove Apache so I can start over? Worst case, I have a timemachine backup, so I can always just restore that... Thanks in advance.

• Debugging a Drobo that chokes Windows 7x64 When Plugged In

  - by Pridkett

  I've had a love hate relationship with my Drobo for a long time. After two years of using it on a Linux box, I moved it over to a Windows 7 machine where it seemed to work just fine for a long time, but it was under very light usage. Mainly backups that never actually happened. Recently I began using it for additional backup services (through CrashPlan, which is great). This means the Drobo gets a lot more usage. Also it means that something interesting happens, the Drobo can choke my system on startup. Here's what I mean: Start computer without Drobo plugged in, CrashPlan and Drobo Dashboard services disabled: 105s Start computer with Drobo plugged in Crashplan disabled, Drobo Dashboard enabled: 250s (and 1 cpu at 100% for a very long time, drobo churning) Start computer with Drobo plugged in, CrashPlan and Drobo Dashboard disabled: 250s (1 cpu at 100% for a very long time, drobo churning) Start computer with Drobo plugged in, Crashplan and Drobo Dashboard enabled: 300s (1 cpu at 100% for a very long time, drobo churning) If I yank the USB plug on the Drobo the CPU usage goes down to nothing very quickly. The slow startup in the fourth scenario is because CrashPlan is trying desperately to load stuff up on the H: drive before it gives up, so I've disabled it for the time being. So here's my question: What the heck is going on when I plug the drobo in? I've fired up Process Explorer and see that the System process is hogging the CPU, specifically it's an ntoskrnl.exe/KdPollBreakIn thread that's going ape. Is this something that's wrong with Drobo? Windows? Any idea on how to find out? If it matters, here's tech info: Athlon 64x2 4400, 2GB RAM, Win7 Ultimate, Drobo USB (2x1TB, 2x320GB)

• Built local glibc, broke system, how do I ssh without parsing the .bashrc?

  - by Mikhail

  The cluster I am on had really old build tools and I needed to use CUDA5. I'm a pretty clever dude and I planned on building the necissary tools. So, I built a local copy of gcc, bintools, and glibc. Everything a CUDA5 could want. All builds finished without error. and I tested gcc and bintools. Everything was wonderful and I built and ran a few of the programs. I set up the LD_LIBRARY_PATHs in the .bashrc and logged back in, expecting a productive night ahead. To my horror I realized that everything is dynamically linked. Now I can't do simple commands like ls [ex@uid377 ~]$ ls ls: error while loading shared libraries: __vdso_time: invalid mode for dlopen(): Invalid argument and I can't do commands to fix the problem like rm or vim! Is there a way for me to ssh but also to ignore .bashrc file? Any suggestions are much appreciated. This machine is obviously under maintained and I don't know when I could have administrator support.

• HTB.init / tc behind NAT

  - by Ben K.

  I have an Ubuntu 10 box that I'm trying to set up as a bandwidth-shaping router. The machine has one WAN interface, eth0 and two LAN interfaces, eth1 and eth2. NAT is configured using MASQUERADE as described at InternetConnectionSharing. I'm mostly concerned with shaping outbound traffic from the LAN interfaces -- in the end, I'd like to end up with a hard 768Kbps limit per-LAN-interface (rather than a limit on eth0 pooled across all interfaces). I installed HTB.init, and riffing on the examples, tried to set this up on eth1 by putting three files into /etc/sysconfig/htb: /etc/sysconfig/htb/eth1 DEFAULT=30 R2Q=100 /etc/sysconfig/htb/eth1-2.root RATE=768Kbps BURST=15k /etc/sysconfig/htb/eth1-2:30.dfl RATE=768Kbps CEIL=788Kbps BURST=15k LEAF=sfq I can /etc/init.d/htb start and /etc/init.d/htb stats and see information that /seems/ to suggest it's working...but when I try pulling a large file via the WAN interface the shaping clearly isn't in effect. Any suggestions? My guess is it has something to do with where the shaping falls in the NAT chain, but I really have no idea where to begin troubleshooting this. ---- Update: Here's my /etc/init.d/htb list output, it seems to make sense -- the default rate for eth1 is 768Kbps? ### eth0: queueing disciplines qdisc htb 1: root refcnt 2 r2q 100 default 30 direct_packets_stat 0 qdisc sfq 30: parent 1:30 limit 127p quantum 1514b perturb 10sec ### eth0: traffic classes class htb 1:2 root rate 768000bit ceil 768000bit burst 1599b cburst 1599b class htb 1:30 parent 1:2 leaf 30: prio 0 rate 6144Kbit ceil 6144Kbit burst 15Kb cburst 1598b ### eth0: filtering rules filter parent 1: protocol ip pref 100 u32 filter parent 1: protocol ip pref 100 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 100 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:30 match 00000000/00000000 at 12 match 00000000/00000000 at 16 ### eth1: queueing disciplines qdisc htb 1: root refcnt 2 r2q 100 default 30 direct_packets_stat 0 qdisc sfq 30: parent 1:30 limit 127p quantum 1514b perturb 10sec ### eth1: traffic classes class htb 1:2 root rate 768000bit ceil 768000bit burst 1599b cburst 1599b class htb 1:30 parent 1:2 leaf 30: prio 0 rate 6144Kbit ceil 6144Kbit burst 15Kb cburst 1598b

• Is it possible to install ffmpeg and x264 on a Synology Diskstation 209?

  - by Kieran Benton

  Hi, Complete linux novice here! :) I'm trying to get my brilliant DS209 NAS box to do some transcoding for me of a few AVI videos to a format suitable for my Apply iTouch - yes I could do it with another machine and Handbrake but it would be really useful to offload some of this to the NAS to do overnight. I've managed to install ipkg onto my DS209 NAS box and have played around with installing some packages (binutils, mono, bash etc). I've even managed to install ffmpeg from ipkg and put together the correct command line profile to do the encoding as a .sh file: time ffmpeg -y -i $1 -f mp4 -title $2 -vcodec libx264 -level 21 -s 426×320 -b 512k -bt 512k -bufsize 4M -maxrate 4M -g 250 -coder 0 -threads 0 -acodec libfaac -ac 2 -ab 64k $3 However running this I get a missing dependency on libx264. I've tried building this from the latest source in git, but I get errors during the make process that I just don't understand (way out of my depth). encoder/set.c: In function 'x264_sei_version_write': encoder/set.c:491: error: 'X264_VERSION' undeclared (first use in this function) encoder/set.c:491: error: (Each undeclared identifier is reported only once encoder/set.c:491: error: for each function it appears in.) make: *** [encoder/set.o] Error 1 Can anyone else try building it or give me a pointer as to what I can do to get this going? Its been a good learning experience so far! Thanks.

• VPN from Windows XP to OpenSwan: correct setup?

  - by Gnudiff

  Main question is what I am doing wrong in my OpenSwan or L2TP client setup? I am trying to create a Linux OpenSwan VPN connection from Windows XP machine, using preshared key and the builtin Windows XP L2TP IPsec option. I have followed the instructions in Linux Home networking Wiki for setting up OpenSwan and a guide to making it work with the Windows XP client, but am now stuck. The net setup is as follows: [my windows client, private IP A]<->[f/wall B]<-internet->[g/w X]<->[Linux OpenSwan server Y] A - private subnet /24 B - internet address X - internet address /24 Y - internet address on same subnet as X What I essentially want is for computer with A address to feel and work, as if it was in X subnet for purposes of outgoing and incoming TCP and UDP connections. My OpenSwan setup is as follows: /etc/ipsec.conf (AAA and YYY indicates ip address parts of A and Y addresses): conn net-to-net authby=secret left=B leftsubnet=AAA.AAA.AAA.0/24 leftnexthop=%defaultroute right=Y rightsubnet=YYY.YYY.YYY.0/24 rightnexthop=B auto=start the secret in /etc/ipsec.secrets is listed as: B Y : PSK "0xMysecretkey" where B & Y stand for respective IP adresses of gateway B and linux server Y My L2TP WinXP setup is: IP of destination: Y don't prompt for username security options: typical, require secured pass, don't require data encryption, IPSec PSK set to 0xMysecretkey networking options: VPN Type: L2TP IPSec VPN; TCPIP protocol (with automatic IP address assignment) and QOS packet schedulers enabled The error I get from Windows client is 789: "error during initial negotiation"

• Gerrit ssh key setup on windows server

  - by hotpotato

  I am attempting to configure google's 'Gerrit' code review web app on a Windows server 2008 virtual machine on our internal network. We are using Apache Tomcat (6.0.36) to host the web app and have deployed the gerrit.war to tomcats webapp folder, setup the context.xml, web.xml etc for the web app correctly i believe. However when i startup Tomcat using the $CATALINA_HOME/bin/startup.bat i get the following message in the tomcat logs: *Dec 07, 2012 1:03:54 PM org.apache.catalina.core.StandardContext listenerStart SEVERE: Exception sending context initialized event to listener instance of class com.google.gerrit.httpd.WebAppInitializer com.google.inject.CreationException: Guice creation errors:* 1) No SSH keys under C:\Gerrit\config\etc while locating com.google.gerrit.sshd.HostKeyProvider at com.google.gerrit.sshd.SshModule.configure(SshModule.java:90) I have created a is_rsa.pub SSH key and placed it in the specified directory to no avail. I have been googling this for about a week now and can't seem to find any information about the file or format it is expecting... documentation on setting gerrit up on windows seems hard to come by! Can anyone provide useful information about how to correctly configure a host SSH key in this context?

• Easy GUI way to auto scale EC2 and RDS: aws console, scalr, ylastic...?

  - by Zillo

  I am managing all my instances with the AWS Management Console (the GUI web console) but now I want to use Auto Scale and it seems that this can not be done with that console. Yes, there is CloudWatch but I can only create alarms (e-mail notifications), it seems that CouldWatch needs you to add the auto scale policy in some other place (by command line console?). I would like to use some easy GUI interface. Ylastic and Scalr seems to be a good option. Which one do you think is better? Regarding Scalr, is there any difference between the open source software Scalr and the service Scalr.net? I mean, is the GUI interface the same? I like the idea of the Scalr because I do not need to give my Secret Access Key to a third party (like in Ylastic or in Scalr.net) One question about the Scalr software, it has to be installed in the instances or it must be installed in another machine? Do I need to setup again all my security permissions, AMIs, snapshots, etc. or I can use AWS Management Console for everything and Scalr just to auto scale.

• None of usb-controllers are working after a crash

  - by Cray

  So I have a GA-p35-DS4 mboard with a Q6600, running windows7-x64. After a random crash with a bluescreen (not caused by anything particular as I recall), none of the usb-controllers are working. (And none of the devices connected to those usb ports). All the controllers are showed up in the device manager, but every one has a warning-icon (as they are not functioning properly). The windows identifies them correctly, it shows exactly the model of each controller, and it says that the driver is installed. Now, when I try to reinstall the driver (Update driver menu item in the device manager), it tries to find it, finds the driver, but quits saying that the driver was found but could not be installed. Additionally, it displays "This operation requires an interactive window station", whatever that means... Now get this, the same thing happens with a new pci-usb controller card! It is found (actually each time the machine starts, it is found as new hardware), but trying to install drivers leads nowhere, I am getting the same message about an interactive window station. (tried to install drivers from the acoompanying CD) I have tried deleting those devices from device manager and let windows find them again, but that leads to same results. None of the ports on this extension card work either. This should not be a hardware problem, a usb keyboard connected to the builtin usb controller works in bios, and even in another OS running the same computer (old xp installation) What to do? Will I have to reinstall? Can deleting infcache.1 help? Is there some way to let windows remove all old drivers and try to find all hardware again, this time only looking for drivers on a windows install disk or something?

Listen 443 NameVirtualHost [ my first IP - some site is running SSL successfully using it ]:443 </IfModule> <IfModule mod_gnutls.c> Listen 443 </IfModule> /etc/apache2/sites-enabled/mysite.conf: <VirtualHost [my second IP ]:80> ServerName mysite.com Include /var/www/mysite.com/djangoproject/apache/django.conf </VirtualHost> Then when visiting http[mysite].com:80 or http[mysite].com (:// removed because serverfault doesn't allow me to post hyperlinks), I get: An error occurred during a connection to [mysite].com. SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long) My guess is that the configuration file is not being picked up, and apache is therefore looking for the default-ssl file, which is not in conf-enabled. If I were to configure that file properly, it seems I would successfully connect to whatever default directory is specified in the default-ssl file. But I want to connect to my website. Any ideas? Thanks in advance!

• Centos 6.2 Fresh 'Basic Server' install networking issues

  - by RWC

  I've had a /29 provisioned on a network port for a server and am trying to at least configure the machine so I can ssh into it. It's Centos 6.2 x64 with the Basic Server install. Currently not able to ping gateway or any address for that matter. For reference: Default Interface: em2 Network ID: 66.*.*.0/29 Gateway: 66.*.*.1 Broadcast: 66.*.*.7 Please see my following configs: /etc/sysconfig/network-scripts/ifcfg-em2 DEVICE=em2 NM_CONTROLLED=yes ONBOOT=yes HWADDR=Not Important TYPE=Ethernet BOOTPROTO=none IPADDR=66.*.*.2 PREFIX=29 DNS1=8.8.8.8 DNS2=8.8.4.4 DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System em2" NETMASK=255.255.255.248 USERCTL=no $: route -n Destination // Gateway // Genmask // Flags // Metric // Ref // Use // Iface 66.*.*.0 0.0.0.0 255.255.255.248 U 0 0 0 em2 169.254.0.0 0.0.0.0 255.255.0.0 U 0 1003 0 em2 0.0.0.0 66.*.*.1 0.0.0.0 UG 0 0 0 em2 $: route Destination // Gateway // Genmask // Flags // Metric // Ref // Use // Iface 66.*.*.0 * 255.255.255.248 U 0 0 0 em2 link-local * 255.255.0.0 U 0 1003 0 em2 default 66.*.*.1 0.0.0.0 UG 0 0 0 em2 $: cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=excalibur.domain.com GATEWAY=66.*.*.1 Keep in mind that I cannot even currently ping the gateway which is quite confusing for me. My /etc/hosts are configured correctly with the *.2 address. I'm not concerned with getting all of the addresses on the /29 up and running yet, just one so I can at least ssh in. Thanks!

• How can I recover from SharePoint configuration errors after promoting the server to a Domain Controller?

  - by jjr2527

  I have a SharePoint 2010 VM setup in VirtualBox and I was using local machine accounts to handle security on the server. While preparing for a demo it came time to have some meaningful users on my VM image. I followed some docs on promoting my server to a Domain Controller in a new forrest. So now I have [MachineName].SPDEMO.CONTOSO.com and I can add users as needed. However, when I try to connect to my SharePoint sites I am getting a white screen with the error: "Cannot connect to the configuration database" I changed the pool identity account of each of my IIS app pools to the new Administrator account and started the services successfully but I can't get the SQL services to start up. When I try to start them I get the following error: Windows could not start the SQL Server (MSSQLSERVER) on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 17058. In the event log I see the following error: The SQL Server (MSSQLSERVER) service terminated with service-specific error %%17058. Can I recover from this or should I roll back or just uninstall the Domain Controller role. I'd like to keep the server as a standalone DC so I can do some user profile creation/management but I need the SharePoint bits to work as well.

• Local SSL connections are causing redirect loop (after Ubuntu update)

  Following a recent Ubuntu update, my local websites are no longer serving their pages over SSL.

• Make isolinux 4.0.3 chainload itself in VMWare

  - by chainloader

  I have a bootable iso which boots into isolinux 4.0.3 and I want to make it chainload itself (my actual goal is to chainload isolinux.bin v4.0.1-debian, which should start up the Ubuntu10.10 Live CD, but for now I just want to make it chainload itself). I can't get isolinux to chainload any isolinux.bin, no matter what version. It either freezes or shows a "checksum error" message. I'm using VMWare to test the iso. Things I have tried: .com32 /boot/isolinux/chain.c32 /boot/isolinux/isolinux-debug.bin (chainload self) this shows Loading the boot file... Booting...

Peter Anvin et al isolinux: Starting up, DL = 9F isolinux: Loaded spec packet OK, drive = 9F isolinux: Main image LBA = 53F00100 ...and the machine freezes.

• Blank displays after inactivity, mouse cursor not showing up

  - by Mike Christiansen

  I have a Windows 7 Enterprise x86 machine that is exhibiting some strange problems. After some inactivity (it varies how long it takes), when I come back to my computer, both of my monitors are black. The monitors are on, with a black display. Moving the mouse and pressing keys on the keyboard do not work. This happens at least once a day. When I first encountered the issue, I performed a hard shutdown and restarted the computer. About 10% of the time when I did this, the resolutions on my monitors were messed up. The native resolution on the primary monitor is 1600x900, and the native on my secondary is 1440x900. None of the widescreen resolutions would be present in the display properties. I had 800x600, 1024x768, and 1280x1024. As a workaround to this issue, I've found that if I plug in my secondary monitor as the primary monitor, and leave the secondary unplugged, then Windows will start in 1024x768 on the secondary. Then, I can use Windows 7's "Detect" feature and it finds the 1440x900 resolution, and sets it. Then I have to connect the primary monitor to the secondary port and set it as the primary. Then I can switch the two cables, putting the primary into the primary, the secondary into the secondary. Then use the "Detect" feature again, and it finds the correct resolutions. Some time after performing the above, I discovered that when the screens were blanked, I could simply press "Control+Alt+Delete", type in my password, and everything comes up fine - except my mouse cursor. All applications and features work as intended, except there is no mouse cursor (the mouse actually works though...). I have the "Show location of pointer when I press CTRL key" option selected, so I can press CTRL and use my mouse as normal - but I have no actual cursor. When the computer is in this state, UAC is also not functional. Whenever a UAC prompt appears, the screens go black (the original symptoms) and I have to press Escape to exit UAC. Because of the above symptoms (the UAC black screen thing, etc) I beleive winlogon.exe may be the culprit. However, I have no idea how to fix it. I am unable to restart winlogon.exe due to the problems I am having with winlogon.exe (the UAC black screen) Looking for any ideas.... More information Windows 7 x86 Enterprise Domain environment (I have a secondary account with administrator rights) Dell Optiplex 960 Cannot perform "optional" windows updates due to an activation issue (I am testing a windows 7 image, and an activation infrastructure has not been created yet. However, this issue was happening before I was unable to perform windows update, and windows was up to date at the time Updated video card driver (as an attempt to fixing the resolution issue) Disabled all power saving options Please let me know what else you need to help me solve this issue! Thanks in advance, Mike
