• SLA Violations - Compensation expectations and vague contracts

  - by llllxllll

  Tagging this as cautionary tale. I took over for an admin a year and a half ago, and reviewed the 3 year contract with our ISP. There were no specific SLA promises in the contract that I found, and have been meaning to review the contract with our rep. Of course, we had an outage this past week that resulted in almost four days of downtime !!!!! This involves eff-ups of epic proportions on our ISP's part and a telco they colocate with. Details can be provided. I am the network / systems / purchasing / and helpdesk at my company...and am willing to fight with the ISP. I also have more management that can get involved, including the name on the contract. First, if there are not concrete guarantees about compensation and downtime, we are screwed right? Two, if we want out of our contract, does anyone have experience going the legal route, and if so, who knows a lawyer? =)

• Windows 7 Image Restore with a smaller hard drive

  - by Vaccano

  I have a 500 GB drive that I have made a system image of. I would like to move that to a 250 GB drive (because it is a Solid State drive). I have made a Windows 7 Backup Image of my 500 GB drive. I am currently only using 163 GB of that drive. Can I just restore that to the target drive or will the restore be expecting a 500 GB drive? If it is expecting it I can shrink my partition to less that 250 and backup again. But I would rather not if that is not needed. Will the restore realize that it is not using all the space and just take what it needs?

• Navigation keys on numeric keypad randomly stop working

  - by Tom Hughes

  Shortly after a restart, the arrow and navigation (Home, End...) keys on my numeric keypad will randomly stop working, and -- regardless of the state of the NumLock -- return only numbers. I notice this the most in browser applications (like this edit box) but the same effect is true on the command line and in desktop applications like Word. I swapped keyboards and now use a Microsoft keyboard (both are USB keyboards) but the same behavior persists. I also tried a clean boot to clean out startup programs but this made no difference. The separate arrow keys and navigation keys between the QWERTY keys and the numeric keypad work fine, but my strong preference (dating back to DOS and MS Flight Simulator) is to use the navigation keys in the numeric keypad.

• selinux permissive and type targeted

  - by krisdigitx

  i am running centos 6.2 recently i noticed that apache was running with selinux enabled # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=Permissive # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted i noticed that these errors were coming on dmesg type=1400 audit(1354453732.704:9056368): avc: denied { name_connect } for pid=39006 comm="httpd" dest=11211 scontext=unconfined_u:system_r:httpd_t:s0 tcontext=system_u:object_r:memcache_port_t:s0 tclass=tcp_socket type=1400 audit(1354453735.777:9056369): avc: denied { name_connect } for pid=39046 comm="httpd" dest=6379 scontext=unconfined_u:system_r:httpd_t:s0 tcontext=system_u:object_r:port_t:s0 tclass=tcp_socket i then enabled /usr/sbin/setsebool httpd_can_network_connect=1 and this stopped the errors and also the webpages started to work. My question is if selinux is in permissive mode will selinuxtype=targeted enforce any polices? if not how did it solve the problem with apache as selinux was already in permissive mode?

• How to configure remote access to multiple subnets behind a SonicWALL NSA 2400

  - by Kyle Noland

  I have a client that uses a SonicWALL NSA 2400 as their firewall. I need to setup a second LAN subnet for a handful of PC. Management has decided that there should be a second subnet even though intend to allow access across the two subnets - I know... I'm having trouble getting communication across the 2 subnets. I can ping each gateway, but I cannot ping or seem to route traffic fron subnet A to subnet B. Here is my current setup: X0 Interface: LAN zone with IP addres 192.168.1.1 X1 Interface: WAN zone with WAN IP address X2 Interface: LAN zone with IP address 192.168.75.1 I have configured ARP and routes for the secondar subnet (X2) according to this SonicWALL KB article: http://www.sonicwall.com/downloads/supporting_multiple_firewalled_subnets_on_sonicos_enhanced.pdf using "Example 1". At this point I don't minding if I have to throw the SonicWALL GVC software VPN client into the mix to make it work. It feel like I have an Access Rule issue, but for testing I made LAN LAN, WAN LAN and VPN LAN rules wide open with the same results.

• how to run an AFS file server on a specific ethernet card (in Debian)

  - by listboss

  I have a linux box running Debian server with minimal number of packages (so no GUI for network management). The box has two ethernet cards, one of which (eth0) is connected to a Mac OSX computer using a cross-cable. I can bring up eth0 and assign a static ip (10.10.11.16) to it. This way I can ssh to the box through the cross-cable. This is what I run on Linux box: ifconfig eth0 10.10.11.16 netmask 255.255.255.0 up I also installed/started a file server (AFS) on Debian. So far, the file server can only be accessed through eth1 which is exposed to my home LAN and www. My goal is to set up the file server so that it's only visible through eth0. Is this possible? and if yes, how can I do it?

• How to set Brocade 200E SAN Fabric Switch Port Health Monitoring to "monitored"

  - by Kenny

  Hi, I have a Brocade SAN Fabric Switch, a 200E. When using the web based management interface "SwitchExplorer" I can click the port, and I see "Port Administration Services". In the first screen of data that appreas, there's a row called "Health" which has value "Unmonitored". Do you know how to set this port to be Monitored? And if also - what "Health" monitoring does? I'm hoping it'll email or log if there's a connection or disconnection.. Many thanks for looking... Kenny

• Using symbolic links with git

  - by Alfredo Palhares

  I used to have my system configuration files all in one directory for better management but now i need to use some version control on it. But the problem is that git doesn't understand symbolic links that point to outside of the repository, and i can't invert the role ( having the real files on the repository and the symbolic links on their proper path ) since some files are read before the kernel loads. I think that I can use unison to sync the files in the repo and and the their paths, but it's just not practical. And hard links will probably be broken. Any idea ?

• Load Balancer recommendations

  - by delerious010

  I provide hosting service for about 250 clients to date, and this is increasing on a monthly basis. For each client, I have 2 "services" configured for L4 balancing / persistence .. one on port 80, another for port 443 which redirects to another internal port as well as 4 servers per service. This equates to a total of 500 "services" and 2000 "servers". I'm currently running with a couple CoyotePoint load balancers, and have had a look at some Barracudas but so far I'm really not impressed by those. Could anyone recommend some good load balancers which would be able to support this sort of load ? And which offer a good API, or shell access to automate management.

• Applying the Windows Experience Index to Servers

  - by Scott

  I finally convinced upper management that we need a computer replacement plan, and I've been tasked with making an inventory of what we have and determining what needs to be replaced this year, next year, the year after, etc. I had to use some sort of criteria to back up my recommendations, so I decided to try using the Windows Experience Index. I've determined the CPU and Memory scores for all of our desktops and servers using community data. I also feel fairly successful in assigning a WEI score to each user based on their computing needs. I'm struggling with assigning a WEI score to the various servers that we have: file server, database server, Exchange server, backup server (for doing backups), web server. Suggestions would be appreciated.

• Squid traffic tunneled through VPN

  - by NerdyNick

  So what I'm trying to do is have a Squid Proxy run on 1 machine along side a VPN connection. What I want to happen is all traffic running though the Squad Proxy would run though the VPN for its outbound. ie Desktop - (Squid Proxy - VPN) The goal is to allow my desktop selective tunneling through the VPN. So that Instant Messaging and the like that do not need to run through the VPN can go through my normal traffic. Typically I would go though a SSH Proxy but currently am forced to use VPN to gain entry into the office, and a Squid proxy seemed like it might work out the easiest for what I am needing. EDIT Realize I forgot to actually state what problem I'm running into. I have the Squid setup and verified it works, but once I connect to the VPN. All requests to Squid get accepted but Squid is unable to make the request over the VPN. So the client ends up just sitting there.

• Recover from running "route -f"

  - by James L.

  I was trying to capture localhost traffic with Ethereal, which doesn't work without re-routing localhost traffic to your router gateway. I didn't get the route command quite right, and messed up my routing table. I typed route -f to clear the routing table and rebooted, but when I finished rebooting, the routing table wasn't restored to its original state. I didn't use the -p parameter, so none of my changes should have persisted after a reboot. What can I do to restore the routing table to its default routes?

• Gmail firing background tasks in Chrome and Firefox

  - by Keith Bloom

  I am experiencing a strange problem with Gmail running on Vista and it started when WindowsUpdate last patched my computer. Since then when Gmail is open in either Chrome or Safari the pointer changes to the Working in Background state every couple of seconds. You can imagine how distracting this is. I have never used Gmail in IE before so I loaded it up, Gmail wanted to load the GoogleTalk ActiveX control which I declined. Now Gmail in IE, I'm using version 8, didn't fire these background processes so I'm thinking it has something to do with GoogleTalk. Has anyone experienced this problem? Also does anyone know how to disable GoogleTalk in FireFox of Chrome.

• How do I restore a database on a remote SQL server 2005 from a local backup?

  - by MatsT

  I have been given access to (parts of) a remote SQL Server 2005 with SQL Server authentication in order to be able to make changes to a database without involving other people who is not working on the project. The database have been created on my local machine. Is there any way to restore the remote database from a backup file on my local computer? I do not currently have access to the filesystem on the remote server. EDIT: To clarify, the access I have is that i can log in to the server via the SQL Server Management Studio. I have one connection to my local database server and one connection to the remote server. What I basically want to do is copy the database from one connection to the other.

• Notebook fan spinning at max after trying Linux

  - by Igor Kulman

  I have a Thinkpad T420 (4178-BSG) I use with Windows. The fan (cpu) was always very quiet and I was completely satisfied with it. A few days ago I booted Backtrack Linux from a flashdrive and the fan started to spin at maximum and was very loud. The problem is that this state persists. When I start the Thinkpad and boot Windows as usual the fan start spining at max and never stops. It drives me mad. It looks like somehow the Linux change some settings and I have to suffer. I tried reseting BIOS, updating BIOS, nothing helpes. I even removed the keyboard, looked at the fan but there is no dust.

• VMWare Host needing ESXi 5.0 - Running on a 2008 R2 Host?

  - by Great Big Al

  I have a VMWare image supplied by my Phone System provider which manages a contact management interface, they tell me that VMWare EsXi5.0 is the highest supported host. I'm used to MS HyperV and have no VMWare experiance. At present I have this guest running on a simple desktop PC running ESXi5.0.0, I'd idealy like to run this guest (it's Windows 7 with their software already installed and configured) on a Windows 2008R2 server I have available, as I said, I'm used to HyperV and I can't easily identify if there is a version of VMWare that supports ESXi5.0 guests that will run on a Windows 2008 R2 server host. Is there such a product, what's it called, and with one guest can I run it without purchasing a license? Thanks

• Numlock on when computer is off

  - by George Duckett

  I have a desktop PC which was recently moved. Since moving I've noticed that even while the PC is turned off (but wall socket turned on) the NumLock LED on the keyboard is on. It may have been doing this before the move, but I've only noticed it now. Maybe it matters that the keyboard is connected via a shared mouse/keyboard PS/2 port and I'm running Windows 7. I've not checked whether the LEDs are just keeping whatever state they were in when I turned the PC off but will do this if that information could be relevant. Why does the led stay on when the PC is turned off and how can I prevent this?

• Error while starting web application.

  0 When you right-click a Web site in the Microsoft Internet Information Services (IIS) Microsoft Management Console (MMC) snap-in, and then you click Start, the Web site does not start and you receive the following error message: The process cannot access the file because it is being used by another process. What have to do. To resolve this issue i got this solution form link http://support.microsoft.com/kb/890015 As: You must use the Netstat.exe utility at the command line to see if another process is using port 80 or port 443. But how to ensure that is these Ip are in use or not ? in terms of status ? What should its status ? Second solution is : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\ListenOnlyList. But this key is not found .

• AWS Elastic load balancer doesn't decrease instances from Alarm Trigger

  - by jchysk

  I have a load balancer that I created an auto-scaling-group and launch-config for. I created the auto-scaling-group with a min-size of 1 and max size of 20. I have a scaledown policy: as-put-scaling-policy SBMScaleDownPolicy --auto-scaling-group SBMAutoScaleGroup --adjustment=-1 --type ChangeInCapacity --cooldown 300 Then I set up an alarm: mon-put-metric-alarm SBMLowCPUAlarm --comparison-operator LessThanThreshold --evaluation-periods 1 --metric-name CPUUtilization --namespace "AWS/EC2" --period 600 --statistic Average --threshold 35 --alarm-actions arn:aws:autoscaling:us-east-1:policystuffhere:autoScalingGroupName/SBMAutoScaleGroup:policyName/SBMScaleDownPolicy --dimensions "AutoScalingGroupName=SBMAutoScaleGroup" When average CPU usage over 10 minutes is under 35, in CloudFront the alarm shows up as "In Alarm State" but doesn't decrease the number of instances. Also, if there's only one instance running it'll spin up another to 2 even if a scale up alarm isn't hit. It seems like the default value is just set to 2 somehow. How can I change this?

• Is there a way to find what values comes from what file in HAL under Ubuntu?

  - by vava

  I've been playing with multitouch on my Thinkpad and read a few tutorials on how to setup it. One of them mentioned /usr/hal/fdi/policy/20thirdparty/11-x11-synaptics.fdi, I edited it and enabled SHMConfig through it. Later I found out about /etc/hal/policy/ directory and put some customization for my touchpad there as well in separate fdi file. But now it looks like touchpad doesn't care about my customizations. I have gsynaptec installed and can configure it though GUI, I can configure it with synclient but I can't set any values through fdi files. I even turned off SHMConfig, reverting 11-x11-synaptics,fdi file to it's original state but it seems like SHMConfig still enabled, otherwise I wouldn't be able to configure properties in runtime. So, I was thinking, maybe there's additional hal files I don't know about. How can I find them, particularly ones responsible for turning SHMConfig on?

• squid running out of sockets

  - by drscroogemcduck

  I have a setup where squid sits in front of a java server and acts as a reverse proxy. Recently i've load tested the site and if i fire 100 threads at it each making a request using jmeter i start getting errors in my load test tool like 'no route to host' even though the load test tool and the server are on the same machine. if i run the following command where port 82 is the port my squid server is running on: netstat -ann | grep 82 | wc -l i get 22000 or something and most of them are in TIMED_WAIT. i'm thinking that maybe the huge number of sockets in the TIMED_WAIT state are starving the box of resources.

• Are Plesk server backups useful?

  - by Michael T. Smith

  I'm working for a startup now, and I'm the programmer. Because of our small team size, I'm also handling the server management for now (until we get a dedicated server administrator.) I've never used Plesk before, and the server we're using (a Media Temple Dedicated Virtual server) had it installed when I got here. One of my first jobs was to set up backups: Plesk was already running it's nightly server-wide backups. I created a small script to dump the web app, it's DBs and any assets, tar them, store them, and then copy them to another small server we have (to backup the backups.) But, we're constantly running into hard drive space issues because of the Plesk backups. And I'm wondering, are they useful? If I have the web app and all of it's assets, I could easily enough get another server up and running. Do we need to keep running Plesk's backups? Thoughts?
