• Having trouble setting up my router

  - by indyK1ng

  I just moved into my apartment and the Internet connection is working. It's Comcast in case that matters. Anyway, I'm having trouble setting up my wireless router (Netgear WNR2000) to work with it. Are there any settings that I could be missing? I currently have it set up to use a static IP address and I found the DNS servers I'm supposed to use and the Internet light is green, but I can't get out to the Internet. When I am trying, I'm connecting to an Ethernet port on the back of my router. Is there a setting I'm missing or a setting that I have set wrong? I used the automatic set up wizard to learn that it's a static IP address. Any help would be appreciated. I am currently only able to use my Linux machine, so please make any help in Linux commands. Yes, I can connect to the Internet if I connect to the modem directly and I've been using the web interface when I'm connected to the router, so I suppose I can ping the router. My router detected the connection as using a static IP address, so I connected to the modem directly and figured out what my IP address, gateway, and mask were as well as DNS servers.

• MSSQL Server Management Studio Express 2005 license limit error should not be displayed

  - by Erik Vold

  I just tried restoring a 250MB database from a backup on my local machine, and got the following message: TITLE: Microsoft SQL Server Management Studio Express ------------------------------ Restore failed for Server 'MULTIVIS-A0D9F3\SQLEXPRESS'. (Microsoft.SqlServer.Express.Smo) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=9.00.3042.00&EvtSrc=Microsoft.SqlServer.Management.Smo.ExceptionTemplates.FailedOperationExceptionText&EvtID=Restore+Server&LinkId=20476 ------------------------------ ADDITIONAL INFORMATION: System.Data.SqlClient.SqlError: CREATE DATABASE or ALTER DATABASE failed because the resulting cumulative database size would exceed your licensed limit of 4096 MB per database.

So I did some googling on this error and saw the suggestion to try shrinking my other dbs to free up some space. So I did so on the 4.1gb db and now when I go to 'properties' for that db it says it is taking/using ~2.4gb. So I should have space now I figure, but whenever I try to restore the ~250mb database now I still get the error message above.. I tried restarting as well but that wasn't helpful. Any idea what the issue is?

• Parental Controls in Ubuntu - per user

  - by Hamish Downer

  I would like to set up parental controls on Ubuntu for a friend of mine. I want it so that the child user has the controls set, but the parent user is not restricted. To be clear, they are sharing one computer, so a router based solution won't help. And I would like a set of step by step instructions to do this. Just one way of doing it. I'm an experienced Ubuntu user, happy at the command line. I've spent quite some time googling for this along the way. I hope that the GChildCare project will eventually make this easy, but it is not ready yet. In the meantime, the WebContentControl GUI provides a way of managing parental controls, but apply them to every user on the computer (easy WebContentContol install instructions and detailed instructions, discussion and related links on ubuntuforums). The ubuntuforums post has a FAQ that states that user-specific configuration is not possible with WebContentControl, and then provides 3 links he used to help him do it. But they are far from step by step instructions. There is this thread which is notes along the way and linking to this article about squid and dansguardian. And then to these two dansguardian articles which are somewhat in depth ... So does anyone know of an existing guide to how to set up parental controls on ubuntu with some users not affected? If no one has come up with an answer after a little bit, I'll set up a community wiki answer so we can come up with a guide.

• RAID 5 Install on Ubuntu Server 12.04 [closed]

  - by tarabyte

  Environment: Ubuntu Server 12.04, installing from bootable flash drive Error: No root file system is defined. Please correct this from the partitioning menu. I'm trying to set up a personal file server with software RAID 5. I just got three hard drives for this, but haven't found any solid documentation. I'm unsure what the basic way to partition my hard drives is. Can someone upload a screenshot of their "partition disks" screen so that I can compare with mine (attached)? Should I set the bootable flag? Do I need a /home partition? A /boot partition? Should I "Use [my partition] as: Ext4 journaling file system"? Or make that field "physical volume for RAID"? I am an engineer, but I have only a cursory knowledge of all-things-linux. If you know of any good learning resources I'd be happy to hear about those too (that way I don't have to blindly follow deprecated tutorials online). well, image would be here but i don't have a high enough reputation yet (please vote up :)) Thank you, References I've looked into: https://help.ubuntu.com/community/Installation/SoftwareRAID https://help.ubuntu.com/12.04/serverguide/advanced-installation.html http://forevergeeks.com/setup-ubuntu-server-with-raid-5/

• ssh connection slow when using @hostname.com but now when using @ipaddress

  - by Alex Recarey

  When connecting to a Debian server using ssh, if I use [email protected] (the IP address of hte server) the connection is instant. If however I use [email protected] (a DNS redirected to the IP address of the server) the ssh connection hangs for a 20 seconds before connecting successfully. The ssh logs show the following: [alex@alex home]$ ssh -v -v [email protected] OpenSSH_5.5p1, OpenSSL 1.0.0c-fips 2 Dec 2010 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 and here it hangs during 20 seconds before continuing. I think it might have something to do with reverse DNS or similar (the server does not really "know" it's name is hostname.com, it just has that DNS rediriected to its IP address). I have added the following options to /etc/ssh/sshd_config: UseDNS no GSSAPIAuthentication no to no effect. The server's DNS records in /etc/resolv.conf are configured correctly: ping hostname.com PING sub.domain.com (X.X.X.X) 56(84) bytes of data. 64 bytes from replicant (X.X.X.X): icmp_seq=1 ttl=64 time=0.029 ms 64 bytes from replicant (X.X.X.X): icmp_seq=2 ttl=64 time=0.050 ms?s Thanks for the help. Solution: It seems the DSL router my ISP saddled me with was causing the trouble. Changing my DNS server from 192.168.1.1 (router's IP) to google's (8.8.8.8, always good to know when you are in a hurry) instantly solved the connection delay problem. I am guessing that the 50€ router provided does not cache DNS entries, although I don't understand why pinging the DNS address had no delay, and 20 seconds is too long of a wait, even for uncached DNS. Tnanks again for the help!

• corrupted, hidden, wireless network adapter from "Network Connections" in Windows 7

  - by srihari reddy

  The issue is that when I install a wireless network adapter on my Windows 7 Professional machine I have no connectivity, the system tray icon has a red X. First, I tried the obvious, install updated drivers from the manufacturer. When I did this, the Network Connections icon had gray bars and there was no connectivity. So I tried installling the network adapter on a different computer on the same network and I verified that it does work with no issues. Next, I ran scan disk with no issues. Next, I ran sfc as admin with no issues. At this point I turned to the router and turned SSID broadcast on but that didn't help. I turned MAC address filtering off at the router but that didn't help. Whenever I installed the original network adapter (a wireless N usb adapter with WPA2 TKIP+AES) it showed up as "Wireless Network Connection 2" with a grayed out icon and no connectivity. Lastly, I tried installing two different "verified working" usb wireless adapters on to the Windows 7 Pro machine. The results were the same "Wireless Network Connection 2" that had a green bar icon but no connectivity. I installed the manufacturers software and it indicated the NIC was not there even thought the driver installed successfully in Device Manager. I guess I should mention, I first tried (insanely in vain) to use the (worthless) Windows Network troubleshooter. The results were....drumroll please... There is a problem with the network adapter... well No Duh! Also, during all of this the network adapter is always showing as "Working Properly" in the properties dialogue of Device Manager for the wireless NIC. I checked for hidden devices in Device Manager but there were none. Here is my fundamental question that I've tried to find in the Windows 7 support center with no luck. How do I remove/delete/uninstall network adapters from the Windows 7 registry? in particular hidden, corrupted network adapters, that used to be working.

• HP Officejet 4500 G510n-z Not Showing up in Remote Desktop (Terminal Services)

  - by Greg_the_Ant

  I installed this printer on a windows XP machine. First using the wireless option, and later using USB. In both cases when I connect to my other computer (also Windows XP) via terminal services and check printers in the local resources tab it does not show up on the remote session. I used to have a Samsung connected to my local computer over USB and and that worked fine over terminal services. Things I tried so far: I did read this page and installed the software fix on both computers: (Printers that use ports that do not begin with...) I installed the minimum HP software install on the remote computer and that didn't help either. I also tried running the add new printer wizard on the remote computer: I selected "local printer attached to this computer" and did not check the "automatically.." option. On the next page of the wizard I can select an option for "use the following port". I see options for TS001 through TS009 there. I'm assuming those are coming from the local machine. I tried clicking each one and then checking "have disk" and pointing it to C:\3be8dc611b11322e8ddf8a67\i386\msxpsdrv.inf 1 but for every single TS00.. port it says "The specified location does not contain information about your hardware." Any help would be greatly appreciated. I'm pretty stuck at this point. 1 C:\3be8dc611b11322e8ddf8a67 is the folder I extracted the HP driver software to after I downloaded it.

• How do I install a different OS on a Compaq Presario cq56 with preinstalled SuSE 11?

  - by McCoy

  Thing is, I don't have a clue of Linux systems, I usually use WinXP. Bought a notebook with SuSE 11 on it, because I have my XP licence and thought I could install that if I found the chipset drivers for the hardware (which I'm not completely sure I have the right versions of). Then I thought I'd give it a shot with the SuSE, looked nice enough. But I can't get my external hd to work (tried force mount) and the banshee doesn't do anything like playing video. Since that is one of the two main purposes of this notebook, I need to get that to work. Tried downloading VLC player, but that only works with SuSE 11.1 upwards. So I downloaded a SuSE 11.3 and burned the iso. But surprise, no way the notebook would boot from cd. Same with the XP cd (considered setting up a dual boot). And no, I can't get to BIOS to reset to default, either. So I can basically do nothing else than going online with this thing and that's not enough for me (gamer in withdrawal, yikes!). I need at least to get to my firefox profile on the external hd and be able to watch video. Can somebody please help me? I think at this point I'd prefer to install XP and MAYBE the SuSE 11.3 after that. I'm not a native speaker, so please speak plainly, thanks. :) Edit: if this is impossible, could someone please help me with the external hd mount and video playback? Edit: Found out how to boot from cd by now. But still no XP, because I get bluescreen after bluescreen while setup is loading files. I guess it's the missing SATA drivers...

• Apache, suexec, PHP, suPHP

  - by Chris_K

  While I'm quite comfortable as a Linux user, my Linux Admin-fu is a bit weak. Thus, I'm here looking for guidance with a CentOS server I'm about to build. I need to setup an Apache2 web server for a few of our clients. I want each client's web content to be under their home directory (USERDIR in apache.conf, right?) for the static HTML sites. I want Apache to run as the client (suexec?). Some of their stuff will be PHP apps and I'm under the impression I'll want to look at suphp as well then. So basically I want to look like a small version of a shared web hosting company. Considering how common those are I thought I'd easily find a nice current How-To guide on setting this all up but so far I've had very little luck. I suspect my search words are off. So the questions (feel free to answer any or all): Anyone have some solid links to current/modern guides that would help me set this all up? No, the apache documentation site is not a guide ;-) Since I have a mix of static sites and PHP apps do I want/need both suexec and suphp installed? If so, does that introduce any challenges I should be aware of? Should I be looking at other options instead of suexec and suphp? I plan to give the end users SSH, SFTP or SCP access to their stuff (if that affects anything). Thanks in advance for your help.

• Temporary boot problem after thunder storm - likely causes?

  - by alastairs

  The village where I live was sat under a thunder cloud for most of Friday, and we suffered a few power fluctuations (specifically, what seemed to be split-second outages). When I got back home from work, I found that my PCs had shut down during one of these outages. When I went to boot one of them back up, I couldn't get anything to display on screen, nor did the boot seem to complete correctly. I tried a number of things - unplugging different bits of hardware, swapping graphics adaptors, etc. - to no avail. I thought I was looking at a fried motherboard or CPU. Power seemed to be distributed correctly to the peripherals (the drives all appeared to be working) so I figured it couldn't be the PSU. Eventually I unplugged it from the mains and left it overnight (approx 12hrs unplugged). I tried it again this morning, and it booted up correctly. Woo-hoo! I have all my equipment protected by surge-protected power strips, so I don't think a spike caused these problems. Obviously it has something to do with the power fluctuations, and maybe the PSU in the problem machine got itself confused somehow. The questions are, for future reference and to help people with similar problems: What are the likely causes of the boot failure I experienced? Is a UPS a simple and cost-effective solution, or might other things help prevent this happening in future? What UPS can you recommend (my budget is limited)?

• WTH? Upgrading Ubuntu 9.10 to 10.04 Problem: No Internet Connection?

  - by damx

  Earlier today I tried upgrading my Ubuntu 9.10 Karmic Kaola from the update manager. (FYI: all 9.10 updates were applied prior to this) Everything was going well downloading until I got an error dialog informing me that some software packages weren't downloaded because of an Internet connection. Would say it was halfway thru. Anyway, Was told that the software packages that it did download, however, would kept and I figure it's not a big deal. Just run it again. But first ran Firefox to verify my connection as I haven't had any connection problems. But my internet connection was/is fine as evident by this posting. With that cleared, I ran the update manager again, clicked on "Upgrade" and this time I received "Could not download the release notes. Please check your internet connection" huh? This is my first time dealing w/ Ubuntu and my first upgrade so I am hoping someone can help. Not sure what the problem can be. I am can surf the web w/ no problems. Please help. PS: There was no installing at any point. Just downloading. PSS: The software it managed to download the first time around is now visible in the update manager but don't think I should install as I see in the compiz description it's for v1:0.8-4-0ubuntu2 I figure it's designed for 10.04 and might ruin things further if I install

• Ubuntu xrandr rotate issue

  - by user83544

  I've just bought a second monitor for my PC which happens to be a pivot monitor. I've already read lots of forums related to my problem but haven't come across a solution - I have the same symptoms as dozens of posts but no matter whatever I try it just doesn't work. I've already changed the xorg.conf file and added in the device section just under Driver "nvidia" the following for my second monitor: Option "RandRRotation" "on" When I save and reboot I try to rotate my screen with the nvidia X server settings by choosing the second monitor and clicking either "left" or "right" for the rotation. It immediately exits the nvidia settings window and does nothing. I tried within the terminal by typing: xrandr -o right I get the following error: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 154 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Serial number of failed request: 14 Current serial number in output stream: 14 I actually manage to rotate it with Option "Rotate" "CCW" instead of "RandRRotation". The problem with this solution is that you get the second monitor in the right position, but any window you open on that screen is practically unchangeable. You can't change the size nor move it, making it useless for reading PDFs, which is the main reason why I bought this second screen to help me write my thesis. Any help is really appreciated. sudo lshw -c video hiram@hiram-linux:~$ sudo lshw -c video *-display description: VGA compatible controller product: nVidia Corporation vendor: nVidia Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:16 memory:f8000000-f9ffffff memory:d8000000-dfffffff memory:d4000000-d7ffffff ioport:dc00(size=12 memory:fbd80000-fbdfffff

• Blue screen issue

  - by Jack

  I received several BSOD's that are recorded in the following logs: Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7601.2.1.0.256.48 Locale ID: 3081 Additional information about the problem: BCCode: 50 BCP1: FFFFF95FF8150C10 BCP2: 0000000000000008 BCP3: FFFFF95FF8150C10 BCP4: 0000000000000005 OS Version: 6_1_7601 Service Pack: 1_0 Product: 256_1 Files that help describe the problem: C:\Windows\Minidump\040412-20030-01.dmp C:\Users\Jack\AppData\Local\Temp\WER-33025-0.sysdata.xml ~~~~~ Problem signature: Problem Event Name: BlueScreen OS Version: 6.1.7601.2.1.0.256.48 Locale ID: 3081 Additional information about the problem: BCCode: 1e BCP1: 0000000000000000 BCP2: 0000000000000000 BCP3: 0000000000000000 BCP4: 0000000000000000 OS Version: 6_1_7601 Service Pack: 1_0 Product: 256_1 Files that help describe the problem: C:\Windows\Minidump\040412-32729-01.dmp C:\Users\Jack\AppData\Local\Temp\WER-64319-0.sysdata.xml It seems to occur at random.

• emacs error: "Symbol's value as variable is void: hostname"

  - by Florian Pilz

  After I installed emacs this error occurs every time on startup. It prevents me from installing plugins, e.g. auctex via aptitude. I already tried to install a plugin by hand (rails for ruby), but doesn't work. The error doesn't contain the message "hostname", but the hostname of my PC is displayed ("bloodredangel-ubuntu"). I changed my hostname to "bloodredangel", but the error message stays the same. While I changed my hostname I saw that in /etc/hostname were two entries: 127.0.0.1 bloodredangel-ubuntu I already asked this question in an ubuntu forum but they couldn't help. They recognised an misconfigured /etc/hosts file, which I corrected, but from time to time these incorrect configurations get attached by something. I didn't add them by hand, maybe it has something to do with the issue. The misconfigurations looked like this: 127.0.0.1 127.0.0.1 bloodredangel-ubuntu localhost.localdomain localhost 127.0.0.1 127.0.0.1:8080 bloodredangel-ubuntu localhost.localdomain localhost I didn't found a solution on the internet, so I hope I will find help here finally.

• Slow INFORMATION_SCHEMA query

  - by Thomas

  We have a .NET Windows application that runs the following query on login to get some information about the database: SELECT t.TABLE_NAME, ISNULL(pk_ccu.COLUMN_NAME,'') PK, ISNULL(fk_ccu.COLUMN_NAME,'') FK FROM INFORMATION_SCHEMA.TABLES t LEFT JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS pk_tc ON pk_tc.TABLE_NAME = t.TABLE_NAME AND pk_tc.CONSTRAINT_TYPE = 'PRIMARY KEY' LEFT JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE pk_ccu ON pk_ccu.CONSTRAINT_NAME = pk_tc.CONSTRAINT_NAME LEFT JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS fk_tc ON fk_tc.TABLE_NAME = t.TABLE_NAME AND fk_tc.CONSTRAINT_TYPE = 'FOREIGN KEY' LEFT JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE fk_ccu ON fk_ccu.CONSTRAINT_NAME = fk_tc.CONSTRAINT_NAME Usually this runs in a couple seconds, but on one server running SQL Server 2000, it is taking over four minutes to run. I ran it with the execution plan enabled, and the results are huge, but this part caught my eye (it won't let me post an image): http://img35.imageshack.us/i/plank.png/ I then updated the statistics on all of the tables that were mentioned in the execution plan: update statistics sysobjects update statistics syscolumns update statistics systypes update statistics master..spt_values update statistics sysreferences But that didn't help. The index tuning wizard doesn't help either, because it doesn't let me select system tables. There is nothing else running on this server, so nothing else could be slowing it down. What else can I do to diagnose or fix the problem on that server?

• SpamAssassin bayesian score discrepancies

  - by CaptSaltyJack

  This makes my brain hurt. For some reason, SpamAssassin is giving high scores to certain emails, but when I test them on the command line, they get a low score. This one particular email has this in the header: X-Spam-Flag: YES X-Spam-Score: 8.521 X-Spam-Level: ******** X-Spam-Status: Yes, score=8.521 tagged_above=-9999 required=5 tests=[BAYES_99=3.5, BAYES_999=0.2, HTML_MESSAGE=0.001, NO_RECEIVED=-0.001, NO_RELAYS=-0.001, RAZOR2_CF_RANGE_51_100=0.5, RAZOR2_CF_RANGE_E8_51_100=1.886, RAZOR2_CHECK=0.922, URIBL_RHS_DOB=1.514] autolearn=no Yet when I dump the raw email into a file msg and run sudo su amavis -c 'spamassassin -t msg', I get this output: Content analysis details: (3.8 points, 5.0 required) pts rule name description ---- ---------------------- -------------------------------------------------- 1.5 URIBL_RHS_DOB Contains an URI of a new domain (Day Old Bread) [URIs: cliobeads.com] -1.0 ALL_TRUSTED Passed through trusted hosts only via SMTP 0.0 HTML_MESSAGE BODY: HTML included in message -0.0 BAYES_20 BODY: Bayes spam probability is 5 to 20% [score: 0.1855] 1.9 RAZOR2_CF_RANGE_E8_51_100 Razor2 gives engine 8 confidence level above 50% [cf: 100] 0.5 RAZOR2_CF_RANGE_51_100 Razor2 gives confidence level above 50% [cf: 100] 0.9 RAZOR2_CHECK Listed in Razor2 (http://razor.sf.net/) I'm really confused as to why when the email comes in, it gets a completely different score attached to it than when I run spamassassin -t. Is there some other way I should be testing emails?

I'm clueless, any help would be great and may help restore my sanity!

• Improving abysmal 802.11n wireless network

  - by concept

  I am in desperate need of help to improve the abysmal performance of my 802.11n wireless network. At best I get 30Mbs (this is an internet download) from a technology that boasts 300Mbs, even worse is the LAN where to date best i have ever gotten is 1Mbs.

• VPN Trunk Between Cisco ASA 5520 and DrayTek Vigor 2930

  - by David Heggie

  I'm a bit of a VPN newbie, so please go easy on me ... I'm trying to use the VPN trunking capabilities of the DrayTek Vigor 2930 firewall to bond two IPSec VPN connections to a Cisco ASA 5520 device and I'm getting myself tied in knots and hope someone here with more knowledge / experience can help. I have a remote site with two ADSL connections and the DrayTek box. The main office site has the Cisco ASA device. I am able to setup a single IPSec connection between the two sites on either of the ADSL connections' public IP addresses, but as soon as I try to use the VPN bonding, nothing works. The VPN tunnels are both still up, but the traffic is getting lost somewhere. I suspect it's due to the ASA not knowing how to route the traffic back over the VPN - one minute, traffic from my remote office's network is coming from public ip address #1, the next it's coming from public address #2 and it doesn't know what to do.

• Postfix selective header_checks: smtpd_relay_restrictions vs. smtpd_recipient_restrictions

  - by luke

  Some of my customers implemented commercial software that violate email-RFCs such that we have had to relax our header checks. In consequence, we receive more spam. Prolog: I know the domains (customer.com) and IP-addresses (a.b.c.d/C) these emails come from Kind request for help: Is it possible to setup one Postfix (2.11) instance on Linux such that: It applies only some header checks for emails from .*@customer.com But applies all header checks for all other email sources? I thought of a combination of mynetworks that includes the subnet a.b.c.d/C in smtpd_recipient_restrictions -- allowing all these messages through -- and simultaneously avoid an open-relay with smtpd_relay_restrictions. However, this has not worked out as expected. Any idea or help is highly appreciated. Thanks in advance. Luke ==EDIT== For the current issue, I solved the problem by prepending REDIRECTs to header_checks as follows: /^received: from.*customer.com.*by mail.own.com.*for.*luke@own.*/ REDIRECT [email protected] This works so far as neeeded. Irrespective thereof, I am still looking for a postfix configuration that would turn this text-based setting into an IP-Address-Range based forwarding rule.... Thanks. Luke

• Why can't I install Java?

  - by Patrick

  I've been searching high and low for someone who can help me. I've been trying for a month. A month. to install Java on my new PC to no avail. No tech support forum can seem to help me. It all started while playing tekkit one day. I kept running out of memory (using the 32-bit JRE 7 u45) so I decided to install the 64-bit version. I uninstalled the 32-bit version first, for some reason, and downloaded the 64 bit runtime. In the installer, I go through all the normal screens until the installation progress bar appears. Then, it just sits there. No progress is made. No CPU is used by the installer, or any of its dependencies. The installer will stay like this for hours, days, and in one case a whole week without doing anything at all. I've tried installing older versions, the 32-bit version, even Java 6 and none of them will install. UAC is disabled, I've run regedit, CCleaner, and any other "fix-it" program there is. It's getting to the point where I may just have to wipe my hard drives and start over. I have several applications that require java, so this is an absolute necessity. Please, please, someone have the answer. Here are my system specs: -Intel i7-3770k -AsRock z77 Extreme3 -Samsung 840 pro SSD -WD Caviar Black 1tb

• Cisco QoS Guidence

  - by Kyle Brandt

  I have a 10M connection to the internet that is hooked into a 100M port. I am getting started with QoS, and am hopping for a little guidance on setting it up on a Cisco 3825 router. Right now I am going forward with the idea that I have to implement it on my router, and the provider can't provide QoS for me. How I envision it working is that the QoS will drop or queue packets on my router and that will help prevent a situation where the provider has to start dropping a lot of packets. Right now all I am tasked with is making sure that one of the 3 LANs gets a certain slice (say 3M for Gig Lan1) of the 10M internet connection (But ideally this will be more flexible in the Future). 10M Internet on 100M port on HWIC-4ESW +-----------------------+ | | Gig Lan1 | Cisco 3825 | Lan3 on HWIC-4ESW | | +-----------------------+ Gig Lan2 I need to learn more about QoS, but having a target technology and maybe example configuration will help me wrap my head around the reading I am doing a little more. Which Cisco QoS Technology do you recommend for this particular situation? Have a basic sample config of how this might work? Right now the 10M line is not congested, so this more to have something in place in case it starts to become mildly congested in the future.

• KVM network bridge with two NICs

  - by Eil

  Greetings, I'm trying to set up bridged networking with KVM and am getting nowhere. There are docs and tutorials on the subject, but they all seem to conflict or don't provide enough info. I was wondering if someone can give me a high-level overview of how to get this working. I can probably work out the details myself (configuring the interfaces, adding routes, etc), I just need help on the big picture: how everything is interconnected. I have a RHEL5 server with KVM installed and running. It has two physical NICs, eth0 and eth1 in the same VLAN. I would like to use eth1 for all traffic between the guests and the rest of the network and reserve eth0 for host management, guest migrations, etc if possible. I'm not picky about which one gets the default route, although it would be nice if we could make it eth0. All of the guests will have static IPs. I would prefer that when a new guest is added, the networking configuration only needs to be set from within the guest itself. Basically, I want this: eth0: all host traffic eth1: all guest traffic Open to any other suggestions if this isn't possible or will be kludgy/difficult. Pointers to existing documentation might not be helpful since I've already been though just about everything out there. Thanks for any help.

• Connection reset by peer: mod_fcgid: error reading data from FastCGI server Issues

  - by user145857

  Help is greatly needed for our server. We are experiencing random "Connection reset by peer: mod_fcgid: error reading data from FastCGI server" errors which cause a 500 internal server error. If the page is then reloaded it loads normally as it should. We are running MPM Worker with mod FCGID to handle PHP. We had APC cache enabled but disabled it recently to see if it would fix the problem, but the random mod FCGID errors are still continuing. No other opcode cache is active now. Our settings are below: <IfModule worker.c> MinSpareThreads 25 MaxSpareThreads 150 ThreadsPerChild 25 ThreadLimit 100 ServerLimit 700 MaxClients 700 MaxRequestsPerChild 0 </IfModule> <IfModule mod_fcgid.c> FcgidMaxRequestLen 1073741824 FcgidMaxRequestsPerProcess 2000 FcgidMaxProcessesPerClass 100 FcgidMinProcessesPerClass 0 FcgidConnectTimeout 300 FcgidIOTimeout 900 FcgidFixPathinfo 1 FcgidIdleTimeout 300 FcgidIdleScanInterval 120 FcgidBusyTimeout 300 FcgidBusyScanInterval 120 FcgidErrorScanInterval 12 FcgidZombieScanInterval 12 FcgidProcessLifeTime 3600 </IfModule> The server is a 64 core 2.1 GHZ 94 GB RAM so it has some power. Some of the fcgid timeout settings are higher because we run large reports which take up to 15 minutes. Any help is greatly appreciated! Just to clarify, the random fcgid errors are occurring when a user clicks a page on our site and the 500 error page loads instantly. This is random and occurrs less than 1% of the time but it is still an issue.

• Checkpoint VPN-1 R60 and Windows 7 64 Bit Client

  - by Mohit

  As per my knowledge of checkpoint VPN-1. My company is using checkpoint VPN-1 R 60 ( I guess as I dont know how to check server version) Firewall(VPN Server). Now the problem is that I installed Windows 7 64 bit. But, after my research I found that there are not even one client (SecuRemote/SecuClient) for Win7 64 bit, when Firewall or server is R60. I thought of some open source solutions. Can you guys please suggest me some with the configuration required. As of now, I know the IP of the server. I know my username and password using which I connect and that is not my domain password. that i can confirm to you guys. I am not a network guy. I am more of a developer. But, I need some help in this.So, let me know if I can provide you more details. Please please i need urgent help on this.

• Windows 7 - mysteriously missing free HDD space

  - by sYnfo

  I have Windows7 installed on 50GB (Oops, it should have been 45GB, sorry) partition, and every now and then it gets full, and I have to resize that partition. I always thought it is quite normal. But it happened again today and this time, I'm sure it is not normal, because since last resizing (35GB 45GB) I did not install any new apps or whatever. Also, sum of sizes off all, including hidden & system, root folders and files is ~18GB, yet windows is indicating that all 50GB are used up... Any idea what is going on? EDIT: Great tools everyone! (SourceForge appears to be offline at the moment, I'll check WinDirStat later) Alas, non of them solved my problem just yet... Screenshot from SpaceSniffer: On the right there is some kind of "Unknows Space", any idea what that could be? EDIT2: After those two apps failing to help much I didn't expect it, but WinDirStat actually helped. It showed that those missing 27GB are in my Temp folder (Well, that should have been my first guess anyway). There I found hundreds of ~100MB files, named like HTT????.tmp. After some googling it appears to be a problem with ESET NOD32 antivirus and it's ThreatSense feature. Thank you all for help! :)
