• SQL Server Agent refuses to start

  - by Geo Ego

  I'm having a problem with SQL Server 2005 where the SQL Server Agent suddenly refuses to start. If I attempt to start it through Services, I get the error "SQL Server Agent (MSSQLSERVER) service on Local Computer started and then stopped." In the Application log, I have the following entry: Event Type: Error Event Source: SQLSERVERAGENT Event Category: Service Control Event ID: 103 Date: 5/20/2010 Time: 11:07:07 AM User: N/A Computer: SHAREPOINT Description: SQLServerAgent could not be started (reason: Unable to connect to server 'SHAREPOINT'; SQLServerAgent cannot start). This database has been running fine for four months. It contains a SharePoint configuration database, which two days ago stopped working, throwing me a message that the configuration database cannot be reached. It was then that I realized the SQL Server Agent was not running, and I have been unable to restart it. I have tried running it with both the local system account and the network service account, with the same results. So far, I have tried: Granting the administrators group, network service, and SharePoint SQL Server Agent account public and sysadmin roles on the database. Granting the administrators group, network service, and SharePoint SQL Server Agent account full permissions to the entire MSSQL directory and all files within. I still have no joy.

• SQL Server Backup problem when browsing to the directory

  - by Richard West

  I want to allow a group (eg. 'BackupManagers') who can only preform backup and restore operations on certain databases. When creating the BackupManagers user account I checked db_backupoperator. When the user logs in to create a backup they get an error message similar to the following when the select Tasks - Backup - Click on Add in the destiantion block - click on the "..." button to browse TITLE: Locate Database Files - MYSERVER\SQL2005 E:\MSSQL\Backup Cannot access the specified path or file on the server. Verify that you have the necessary security privileges and that the path or file exists. If you know that the service account can access a specific file, type in the full path for the file in the File Name control in the Locate dialog box. I have confirmed that the user has permissions to the folder. I have even created a share to this folder and had them access it through explorer. They are able to create and delete files within the folder. I have found that if they type in the path to the file instead of using the "..." button to browse the directory tree then they can create a backup file fine. Why is the browse button not working as expected? Thanks!

• Enable CPU fan always on

  - by Gundars Meness

  I am using 3 years old overheating laptop and I want my CPU fan to be spinning 24/7 regardless of the consequences. How to make it spin? The problem is that CPU & GPU heats up to 68°C (154 F) right after boot and never goes down, because CPU fan is not spinning full throttle. It starts spinning faster when temperature goes over 70°C and stops when it reaches seventy again. When doing heavy work on databases, it gets from 70 to 90 in no-time and automatically powers off. Bios does not contain any "fan spin 100%" options, just "spin slowly all the time" and "auto" which is more useless than the first one since my fan doesn't have pwm wire. Currently I'm solving this with cooling stand (3x5V), but it isn't much of a help. I would rather use the CPU fan since it is the only fan directly responsible for cooling down CPU/GPU. But how to make it spin 100% all the time? Should I attach it's red power wire to motherboard to get constant 5V (is there such option?), or is there an option to control it via software? Laptop: Samsung R528 2.3 GHz Intel i3 with Nvidia GeForce 310M Bios: Phoenix 03KT.M003.20100622.KSJ (and that is latest update) OS: Ubuntu 12.04.2 LTS with 3.2.0.51 kernel CPU fan: Image/Description Has 5V 0,4A and only 3 pins, no pwm. P.S. Yes, I did clean everything with alcohol, freed the air vents, changed thermal paste etc; that reduced temperature by 4 degrees.

• Remote Desktop *from* Windows 2008 R2 Server

  - by freefaller

  Summary: how do I create an RDC connection from a Windows 2008 server to another server? Our client will only allow us to connect to their server via a static IP address (which is fair enough), but unfortunately as we're a very small company we don't have one in the office. As a work around, we had the connection working through our old Windows 2003 server (dynamic-cloud from 1and1). .. however we have just rebuilt the server to run under Windows 2008 R2 (don't ask, but it was necessary), and now I simply cannot get the connection working. I have added an "Outbound Rule" to Windows Firewall with Advanced Security (TCP, All local ports, 3389 remote port - I have also tried the other way around). I have added a packet filter IP security rule with the same details. The 1and1 firewall rules (through their online control panel) allows for 3389 TCP and UDP. But it is simply not connecting (yes, the server is definitely on and able to accept connections) with the general error of... Remote Desktop can’t connect to the remote computer for one of these reasons: 1) Remote access to the server is not enabled 2) The remote computer is turned off 3) The remote computer is not available on the network Is there anything obvious I've missed - or something I can use to find out where the request is being blocked? The new server is using the exact same IP address as before, so I don't believe that would be an issue. Unless it's trying to use an IPv6 address rather than the old IPv4 address that it was before? I apologise that I am not a network person by trade, but I know more than anybody else in my office!!

• Multi-IP address zimbra server DNS PTR records and spam

  - by David Fraser

  We have a mail server running Zimbra (ZCS 6.0.8). The server has 5 active public IP addresses in the same subnet. (.226-.230). I currently have A records for each of these (host0.domain.com..host4.domain.com), with the main host.domain.com of the machine pointing to .226. Our host has ended up being listed on the SORBS DUHL list (even though it's in a server farm). According to them you can get removed quickly by checking that your host has an MX record, an A record, and a PTR record that points back to the hostname given in the MX record. I tried setting the PTR records so that each of these addresses resolved back to their A record (i.e. .228 had a PTR to host2.domain.com). However, I then got mail being rejected from other servers because when Postfix (under Zimbra control) sends out mail, it uses the main hostname for the HELO - there doesn't seem to be any way to override it. So the PTR records currently say host.domain.com for all 5 IP addresses. What's the correct way to handle this? Should I have an A record for the domain that points to all the IP addresses (for round-robin handling)? I'm nervous of changes that could cause problems, so I'm wondering what the standard way to handle a multiple-IP-address mail server is.

• Postfix does not work after setting server hostname from plesk

  - by Michael

  I have recently set my server hostname from localhost.localdomain to xx.mydomain.com from the plesk control panel. However after doing this change postfix has stopped working, I tried restarting and regenerating the config files but to no avail. I am not familiar with postfix but I believe there is a setting to be changed in main.cf. Here are the relevant errors I receive: postfix/postfix-script: starting the Postfix mail system postfix/master: daemon started -- version 2.8.4, configuration /etc/postfix postfix/cleanup: fatal: host/service localhost/12768 not found: Name or service not known postfix/pickup: warning: maildrop/E5559996219: error writing 4FA2C996217: queue file write error postfix/master: warning: process /usr/libexec/postfix/cleanup pid 15334 exit status 1 postfix/master: warning: /usr/libexec/postfix/cleanup: bad command startup -- throttling Any ideas? EDIT Setting it back to localhost.localdomain makes it work again. The only references to localhost/12768 I can find in main.cf are: smtpd_milters = inet:localhost:12768 non_smtpd_milters = inet:localhost:12768 Should something be changed here? These two lines stay the same when I change the hostname. EDIT If I comment out the two mail filter lines (the ones shown above) and restart, postfix works with the new hostname. However this is obviously not the ideal solution...

• How to tell which process is hogging my CPU when they don't add up to 100%?

  - by endolith

  Ubuntu's System Monitor applet shows 100% CPU usage continuously. If I click it, the resources tab shows it at 100% continuously, too. If I go to processes, though, to find out which process is the culprit, there is nothing above 10%. If I run top there is nothing above 10%. The individual processes do not add up to 100%. I try killing lots of processes, but the overall usage continues to be 100%. How can I find out what's hogging the CPU? This is an unusual situation on a computer I use daily, which is never anywhere near 100% CPU unless I'm doing something that requires it (like loading 32 Firefox tabs), after which it goes back to a normal idle level. It's not a new install or anything. There is no reason the processor should be maxed out. I'm not sure when it started or if I changed something that caused it to happen. Normally I would use top or System Monitor and find the process that had gone out of control, but I can't find anything with those tools this time. It persists after reboots and everything. And the processor is obviously hot, so it's not an erroneous reading. Update: I tried killing every process, one at a time, until the problem went away, and killing vino-server finally fixed it, even though that process never went above 5%. I had enabled Remote Desktop a few days ago (and have obviously now disabled it). But the question remains: How did a single process manage to use 100% CPU while top only showed that process at 5%? How do I identify culprits like this in the future? Looks like I'm not the only one who's had this problem: Still a problem in both jaunty & karmic. Interestingly, both System Monitor & htop do not show the sum of individual processes being anywhere near 100% cpu.

• usb mouse connecting and disconnecting randomly and often

  - by Kalec

  Yes, I know this question has been asked here before but I can't add to the discussion over there and it did not help me, so here goes nothing. I've bought an acer aspire 5742G about 2 months ago or so and it's been running great, but sometimes I used to hear the windows error beep but I had no idea what was causing it since the "bug" was automatically fixed so fast I couldn't even see an error message (also it kinda always happened when I was busy also, either in a game or while doing my homework). Later on my mouse would simply not work for 3-5 seconds then work again, I thought nothing of it at the time. I also had a problem where it only worked in one usb and one only ... to move it I had to remove the battery, unplug the laptop and hold the power button for 2 minutes to reset the bios settings. Since today though it went nuts ... sometimes it disconnects / reconnects 12 times in 10 seconds and windows just keeps beeping till I unplug it, then it runs smooth for 5-6 minutes then it goes nuts again. Other times it seems like it skips (disconnects for a fraction of a second) other times just for 2-3 seconds. But this is incredibly frustrating. Sometimes the power just goes down (the laser turns off) and well that at least I would understand but this is a rare occurance. Now I know the usb ports work since I have a lot of other devices connected and I tried the mouse on a room m8's laptop so the mouse also works. My only conclusion is that it's an operating system / settings bug and / or problem (I have tried the mouse in all ports by the way). All drivers and bios are up to date (maybe except mouse but i can't seem to update that and the mouse has no name, just a serial number which helps with nothing. Still it worked till today and nothing should have changed any way). I have made sure windows can't shut it down to save power (in device management). Also I tried to delete the drivers and re-install them, rebooting and the power button trick but nothing ... most I have done is get rid of the 12 discconnects / reconnects every 10 seconds :) but that's all :( I would buy a new one but I'm afraid it might do the same thing :| ****EDIT****** Tried the mouse again at a friend but now it didn't even install it's software nor did the update work ... think I'll just buy a new one but I'd still like a suggestion at least so I'll leave this open

• Why Virtual Box won't give me option to create 64 bits guests?

  - by Eduardo Born

  My host is x64 bits Windows 8.1. I downloaded the latest Virtual Box (4.3) and I'm trying to create a VM with a 64 bits Ubuntu OS (ubuntu-12.04.3-desktop-amd64). When I go to New VM wizard, it doesn't give me option to select "Ubuntu (x64)" as I have seen in other people's screenshots, only just "Ubuntu". As a result, the ISO can't boot. I tried in another PC and Virtual Box gives the x64 variants to most listed OS... Control Panel shows x64 OS, x64 processor. My host laptop is a Sony Vaio VPCZ22UGX/N, Intel® Core™ i7-2640M processor. CPUz shows Vx-t is available on my processor, of course. Here is what I tried so far: I enabled IO APIC as required in the docs. I have virtualization enabled in the BIOS. It works fine in VMware. Check that Hyper-V is not running or even installed on my Windows. Same for VMware. I also tried running the command: VBoxManage modifyvm [vmname] --longmode on for that VM, but no change.. I think the issue is really that I can't select x64 variant of the Ubuntu OS for that VM. Other people seem to indicate that's a requirement, but I don't get that option for some reason. I spent a lot of time and can't find what's wrong... Anyone knows what could be missing here? Thank you very much!! Eduardo

• Understanding packet flows over RVI

  - by choco-loo

  I'm trying to get a full grasp of firewall filters and how to apply them on a Juniper EX4200 switch - to be able to block ports, police traffic and shape traffic. The network architecture is as follows internet >-< vlan4000 >-< vlan43 vlan4000 is a public "routed" block (where all the IPs are routed to and the internet gw is) vlan43 is a vlan with public IPs with devices (servers) attached There are static routes and RVI's on the EX4200 to send all traffic via vlan4000's gateway to reach the internet. I've set up filters on both input and output of the respective RVI's and VLAN's - with simple counters, to measure traffic flow from a server inside of vlan43 and a server on the internet. Using a combination of iperf for UDP and TCP tests and fping for ICMP tests - I observed the following, icmp vlan43>internet internet>vlan43 unit4000-counter-in 0 0 unit4000-counter-out 0 0 unit43-counter-in 100 100 unit43-counter-out 0 0 vlan4000-counter-in 6 4 vlan4000-counter-out 107 104 vlan43-counter-in 101 100 vlan43-counter-out 100 100 tcp vlan43>internet internet>vlan43 unit4000-counter-in 0 0 unit4000-counter-out 0 0 unit43-counter-in 73535 38480 unit43-counter-out 0 0 vlan4000-counter-in 7 8 vlan4000-counter-out 73543 38489 vlan43-counter-in 73535 38481 vlan43-counter-out 38938 75880 udp vlan43>internet internet>vlan43 unit4000-counter-in 0 0 unit4000-counter-out 0 0 unit43-counter-in 81410 1 unit43-counter-out 0 0 vlan4000-counter-in 18 7 vlan4000-counter-out 81429 8 vlan43-counter-in 81411 1 vlan43-counter-out 1 85472 My key goals are to set up a few filters and policers, as there will be many more VLANs - that all need protecting from each other and the internet. Then globally limit/police all outbound traffic to the internet Block inbound ports to vlan43 (eg. 22) Limit outbound traffic from vlan43 (to the internet) Limit outbound traffic from vlan43 (to other vlans) Limit outbound traffic from vlan4000 (to the internet from all vlans) Route traffic from vlans via specific routing instances (FBF) The question What I want to understand is why there isn't ever any activity on unit4000 or vlan4000 inbound or outbound counter - is this because there isn't a device on this VLAN - and that the traffic is only traversing it? And with regards to the TCP test - why is there twice as many packets on unit43-counter-in, vlan4000-counter-out and vlan43-counter-in - is this counting both the inbound and outbound traffic?

• IIS7 - how to place application in a folder inside application web site

  - by Nir

  I have a static web site with a blog (an asp.net application), the blog is in a subdirectory of the web site so: example.com/, example.com/Something.htm, example.com/folder/somefile.htm, etc. - are all static files example.com/blog, example.com/blog/categories.aspx, example.com/blog/2011/11/09/post-name.aspx, etc. - all go to the blog app I'm upgrading the static part of the web site to a dynamic site (also an asp.net application) and the blog is incompatible with the new app (the app needs handlers and modules loaded in web.config that don't work with the blog) Also, I have to keep all the old URLs the same - so I can't move the blog to a subdomain or the new app to a folder and the blog generates links based on its folder so clever redirection tricks wouldn't work. Is there a way to place an asp.net application in a folder inside another application (either as a real or virtual folder) so that the root web.config settings don't apply to the application folder? Or some other trick I didn't think of? The system is running IIS7 on Windows Server 2008 64bit, I have full control over the server's configuration. I can't modify the blog's source code but I can edit its web.config and other configuration. I can modify the source of the new application but I can't make it compatible with the blog (most of its usefulness comes from a 3rd party library that is not compatible with the blog). The blog in an asp.net 3.5 webforms application The new root application is an asp.net 4.0 mvc application

• Hylafax / Capi4hylafax: faxgetty does not recognize number of lines

  - by Wrikken

  We've got a T.30 card, 30 working lines on it, but for some reason, if I add more then 30 faxes in the queue at any time (and we're busy enough at peak times that this happens a lot), faxgetty sends faxes to non-existent lines and they appear in the error queue as a 'busy' signal on the line, which results in a lot of failed faxes because the counter of max 3 tries increases rapidly. This is using faxgetty (USE_FAXGETTY="y" in /etc/default/hylafax). I've inherited this thing, so I'm not entirely sure how faxgetty is supposed to know the number of lines. However, if I alter the script to faxmodem (USE_FAXGETTY="n" in /etc/default/hylafax and manually enabling 30 modems), this behavior goes away (new faxes 'wait' for a line to be available before trying to send, so each try / fail is a valid one on a working line, majorly descreasing the amount of failed faxes. However, when researching this almost anyone talks about faxgetty being the preferred, more robust, method, and on top of that for some unexplained reason all FIFO's disappeared for some reason after several errorless hours with faxmodem, forcing a hylafax restart using faxgetty until we figured out why this faxmodem solution failed (which is another question, and somewhat out of scope here). Environment: Debian 2.6.26-2-amd64 capi4hylafax 1:01.03.00.99.svn.300-12 hylafax-client 2:4.4.4-10.1 hylafax-server 2:4.4.4-10.1 Config --hfaxd.conf-- LogFacility: daemon ServerTracing: 0x1ff --hyla.conf-- Host: localhost Verbose: No VRes: 196 TimeZone: local DialRules: "/etc/hylafax/dialrules.europe" --/etc/hylafax/config -- InternationalPrefix: 00 LongDistancePrefix: 0 AreaCode: 99999 CountryCode: 31 DialStringRules: "etc/dialrules.europe" ModemGroup: any:faxCAPI SendFaxCmd: "/usr/bin/wrapc2faxsend" --/etc/hylafax/config.faxCAPI -- SpoolDir: /var/spool/hylafax FaxRcvdCmd: /var/spool/hylafax/bin/faxrcvd PollRcvdCmd: /var/spool/hylafax/bin/pollrcvd FaxReceiveUser: uucp FaxReceiveGroup: dialout LogFile: /var/spool/hylafax/log/capi4hylafax #no, checking this log did not yield anything interesting LogTraceLevel: 4 LogFileMode: 0600 ModemGroup: any:faxCAPI #repeats of faxCAPI2 = faxCAPI30, with of course another devicename/local ident: { HylafaxDeviceName: faxCAPI RecvFileMode: 0600 FAXNumber: ****redacted**** LocalIdentifier: ****some-ident-per-device*** MaxConcurrentRecvs: 0 OutgoingController: 1 OutgoingMSN: SuppressMSN: 0 NumberPrefix: NumberPlusReplacer: "00" UseISDNFaxService: 0 RingingDuration: 0 { Controller: 1 AcceptSpeech: 0 UseDDI: 0 DDIOffset: DDILength: 0 IncomingDDIs: IncomingMSNs: AcceptGlobalCall: 1 } } So in short: How does faxgetty determine the number of lines available? (the man page isn't terribly revealing, and I can't find an appropriate setting in hylafax-config. And how can I get a capi4hylafax/hylafax setup which queues more faxes then lines are available correctly without immediately incrementing the fail count? We will not be receiving any faxes on this machine b.t.w. As I said, I've inherited this thing, so if there are important configuration options I'm not including, please let me know.

• SQL server agent job to execute SSIS package fails, package succeds if run manually

  - by growse

  I've got a SSIS package installed on a SQL server (SQL Server 2012). It's fairly simple and just fetches data from a remote data source and adds it into a local table. The remote connection string is using SQL server authentication, while the local connection is using Windows auth. The remote connection password is protected, and the package was imported setting the protection level to Rely on server storage and roles for access control. If I run the SSIS package manually, it works. If I run it from the command line using dtexec, it works. If I use runas to switch to the domain account that the SQL server agent is running under, and then run the package using dtexec, it works. If I create a SQL Agent job with a single step to run the package, it fails, providing very little detail as to what's going on. I'm guessing it's not able to get the password to log into the remote SQL server, because it fails very quickly. Also, if I tick 'log to table' and view the resulting file, I get the following: Description: ADO NET Source has failed to acquire the connection {0D8F2CD4-A763-4AEB-8B52-B8FAE0621ED3} with the following error message: "Login failed for user 'username'.". If I try to add the password in the connection string manually under data sources in the job step dialog, it refuses to save it, always seeming to remove the 'password' bit of the connection string. I thought that SQL server agent jobs always ran under the context of the account which the SQL server agent is running under. This account is a sysadmin on the local SQL server, and the package works using dtexec under that account, so why would it fail when trying to run as an agent job?

• How to uninstall files and software from a Solid State Drive (SSD)

  - by jasondavis

  I am using a SSD drive just as a main Operation system and software drive. I have a regular spinning disk for data files. I have read that files are not REALLY deleted from a SSD drive when you "delete" them. So here is my situation and hopefully I can get some good advice. Let's say I have Windows 7 Pro x64bit installed on my 80gb Intel SSD. I then have Adobe Photoshop CS4 installed along with 50 other programs installed onto this SSD. I then decide I am done with Adobe Phjotoshop CS4 and want to remove it. I then decide I want to install another version of Adobe Photoshop and a few other software titles. Would I just do the usual, add/remove software from the windows control panel. Or if the software being removed has an "Uninstall" program to run, then run it and uninstall the software? I realize that all this WILL remove the software from Windows 7 but I am wanting to know if there is additional steps that should be taken since it is a solid state drive (SSD)?

• Closing laptop lid and using external display causes mouse to move on it's own

  - by PolishHurricane

  I plugged my ASUS Taichi Laptop into an external monitor via the VGA Adapter that it comes with. It was working fine, but then I configured a power option so I could shut the lid without it going to sleep (so I could use just the external monitor with an external keyboard/mouse). Problem is though, now, when the lid is closed and I move the mouse, the mouse is moving around on it's own, but when I open the laptop lid back up, the mouse is fine. I looked under the lid when it was closed and the display properly shuts off on the laptop. It's not the external mouse/keyboard because I completely unplugged them and it was still happening. Nobody is hacking me or anything, I totally went into airplane mode/pulled the wire. I have a touchscreen, but I put a piece of paper over it and it wasn't doing it. I was thinking it might be the trackpad being touched somehow by the screen when the lid is closed? But I went into windows 8 control panel options and I couldn't find anywhere to disable it (it sees the USB mouse I think).

• Shared firewall or multiple client specific firewalls?

  - by Tauren

  I'm trying to determine if I can use a single firewall for my entire network, including customer servers, or if each customer should have their own firewall. I've found that many hosting companies require each client with a cluster of servers to have their own firewall. If you need a web node and a database node, you also have to get a firewall, and pay another monthly fee for it. I have colo space with several KVM virtualization servers hosting VPS services to many different customers. Each KVM host is running a software iptables firewall that only allows specific ports to be accessed on each VPS. I can control which ports any given VPS has open, allowing a web VPS to be accessed from anywhere on ports 80 and 443, but blocking a database VPS completely to the outside and only allowing a certain other VPS to access it. The configuration works well for my current needs. Note that there is not a hardware firewall protecting the virtualization hosts in place at this time. However, the KVM hosts only have port 22 open, are running nothing except KVM and SSH, and even port 22 cannot be accessed except for inside the netblock. I'm looking at possibly rethinking my network now that I have a client who needs to transition from a single VPS onto two dedicated servers (one web and one DB). A different customer already has a single dedicated server that is not behind any firewall except iptables running on the system. Should I require that each dedicated server customer have their own dedicated firewall? Or can I utilize a single network-wide firewall for multiple customer clusters? I'm familiar with iptables, and am currently thinking I'll use it for any firewalls/routers that I need. But I don't necessarily want to use up 1U of space in my rack for each firewall, nor the power consumption each firewall server will take. So I'm considering a hardware firewall. Any suggestions on what is a good approach?

• Problems mounting HPUX LVM+VXFS filesystem on Linux

  - by golimar

  I have a physical disk from a HPUX system that I need to access from a Debian Linux for ia64 system. From the hpux-lvm-tools project I have the tools to access the HPUX LVMs (Linux LVM has a different format) and I also have the freevxfs driver. I know beforehand that the disk has three partitions, and that the biggest one contains LVM volumes, and some of those are VxFS filesystems. I can see the partitions: # cat /proc/partitions major minor #blocks name 8 32 143374744 sdc 8 33 512000 sdc1 8 34 142452736 sdc2 8 35 409600 sdc3 It finds a VG in one of the disk partitions: # ./vgscan_hpux On /dev/sdc2 - vg1328874723 # ./pvdisplay_hpux /dev/sdc2 PV General Information ---------------------- VG Creation Time Fri Feb 10 12:52:03 2012 Physical Volume ID 1766760336 1328874723 Volume Group ID 1766760336 1328874723 Physical Volumes in VG 1766760336 1328874723 VG Actication Mode 0 - LOCAL PE Size 64 MBs Lvol sizes ---------- lvol1 - 8 Extents - 512 MBs lvol2 - 192 Extents - 12288 MBs lvol3 - 16 Extents - 1024 MBs ... lvol21 - 13 Extents - 832 MBs lvol22 - 224 Extents - 14336 MBs lvol23 - 16 Extents - 1024 MBs Then I activate that VG and some new devices appear in my system: # ./pvactivate_hpux /dev/sdc2 VG vg1328874723 Activated succesfully with 23 lvols. # # ll /dev/mapper/ total 0 crw------- 1 root root 10, 59 Nov 26 16:08 control lrwxrwxrwx 1 root root 7 Nov 26 16:38 vg1328874723-lvol1 -> ../dm-0 lrwxrwxrwx 1 root root 7 Nov 26 16:38 vg1328874723-lvol10 -> ../dm-9 ... lrwxrwxrwx 1 root root 7 Nov 26 16:38 vg1328874723-lvol8 -> ../dm-7 lrwxrwxrwx 1 root root 7 Nov 26 16:38 vg1328874723-lvol9 -> ../dm-8 But: # mount /dev/mapper/vg1328874723-lvol18 /mnt/tmp mount: you must specify the filesystem type # mount -t vxfs /dev/mapper/vg1328874723-lvol18 /mnt/tmp mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg1328874723-lvol18, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so # lsmod |grep vxfs freevxfs 23905 0 I also tried to identify the raw data with the file command and it just says 'data': # file -s /dev/mapper/vg1328874723-lvol18 /dev/mapper/vg1328874723-lvol18: symbolic link to `../dm-17' # file -s /dev/dm-17 /dev/dm-17: data # Any clues?

• Intel NIC X540-T1 non-functional in Ubuntu Server 12.04

  - by Jeff Carr

  I have installed three Intel X540-T1's in servers running Ubuntu Server 12.04, but all are non-functional, no link lights, no packets sent or received, and no connection on ip4 or ip6 whether set up as dhcp or static. Also, dmesg doesn't detect cable connection or disconnection. I updated the default ixgbe driver to Intel's latest version (3.11.33) with no change. The ethernet controller is being reported as X540-AT2 (which might be a problem that I can't figure out how to fix), but the subsystem is X540-T1 so I believe that might be intended. Does anyone have any experience with this that could assist? ifconfig eth2 eth2 Link encap:Ethernet HWaddr a0:36:9f:14:5f:ea inet addr:192.168.101.1 Bcast:192.168.101.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1<br> RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) ethtool -i eth2 driver: ixgbe version: 3.11.33 firmware-version: 0x8000037c bus-info: 0000:08:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes lspci -vvnns 08:00.0 08:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller 10 Gigabit X540-AT2 [8086:1528] (rev 01) Subsystem: Intel Corporation Ethernet Converged Network Adapter X540-T1 [8086:0002] Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr+ Stepping- SERR+ FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 32 bytes Interrupt: pin A routed to IRQ 16 Region 0: Memory at e8000000 (64-bit, prefetchable) [size=2M] Region 4: Memory at e8200000 (64-bit, prefetchable) [size=16K] [virtual] Expansion ROM at e8280000 [disabled] [size=512K] Capabilities: <access denied> Kernel driver in use: ixgbe Kernel modules: ixgbe

• Dos/ Flood Lag even though Port not Saturated

  - by Asad Moeen

  My GameServers had been under some UDP Floods due to which they generated outputs to the attacker which gave the GameServers some huge lags. Thanks to friends at ServerFault that upon different kind of testing, I was able to successfully block the attack. My question is actually something else but it is important to know how the GameServers reacted to the attack and if the machine kept stable or not: 300kb/s Input would cause GameServer to generate 2mb/s Output. So as the Input Rate kept increasing, output rate would reach so high that it would no longer be possible for the GameServer to control it and hence it would give a huge Lag until the attack is stopped. Usually the game server starts to lag when it sends out something greater than 5mb/s and under that is controllable. Theoretically, I was able to receive a 60mb/s output from my GameServer on inputting 10mb/s. Its just the way the GameServer works if not protected. Now on some of my machines, only the GameServer under attack lagged and although the server was generating 60mb/s output, rest of the gameservers on other ports would run fine without lags on the same machine. But there was another machine which also runs on a 100 MBPS Network port, even 1 mbps input ( and ZERO output because attack is blocked ) even on an unused port would give a constant yellow line ( on the Lag-o-Meter ) to all the clients on all GameServers indicating lag because that line is actually blue under normal conditions. It would remain the same even on 50mbps or 900mbps input. I tried contacting the host about it because I believe its the way their Network is bridged, but they can't help me about it. Anyone else knowing about such issues because if 900mbps input does not Saturate the port, how can 1mbps input lag the servers although port is not saturated and enough bandwidth is available?

• mod_cache not working

  - by Pistos

  I have a PHP site that has many dynamically generated pages. I'm trying to turn to mod_cache to help boost performance, because in most cases, content does not change in a given day. I have configured mod_cache as best I could, following examples around the web, including the mod_cache page on apache.org. When I set LogLevel debug, I see a bit of information about the caching that is [not] happening. There are plenty of pairs of lines like this: [Fri Jun 01 17:28:18 2012] [debug] mod_cache.c(141): Adding CACHE_SAVE filter for /foo/bar [Fri Jun 01 17:28:18 2012] [debug] mod_cache.c(148): Adding CACHE_REMOVE_URL filter for /foo/bar Which is fine, because I've set CacheEnable disk /foo, to indicate that I want everything under /foo cached. I'm new to mod_cache, but my understanding about these lines is that it just means that mod_cache has acknowledged that the URL is supposed to be cached, but there are supposed to be more lines indicating that it is saving the data to cache, and then later retrieving them on subsequent hits to the same URL. I can hit the same URL till I'm blue in the face, whether with F5 refreshing, or not, or with different browsers, or different computers. It's always that pair of lines that shows in the logs, and nothing else. When I set CacheEnable disk /, then I see more activity. But I don't want to cache the entire site, and there are many, many different subpaths to the site, so I don't want to have to modify code to set no-cache headers in all the necessary places. I'll mention that mod_rewrite is in use here, rewriting /foo/bar to something like index.php?baz=/foo/bar, but my understanding is that mod_cache uses the pre-rewrite URL, not the post-rewrite URL. As far as I can tell, I have the response headers not getting in the way of caching. Here's an example from one hit: Cache-Control:must-revalidate, max-age=3600 Connection:Keep-Alive Content-Encoding:gzip Content-Length:16790 Content-Type:text/html Date:Fri, 01 Jun 2012 21:43:09 GMT Expires:Fri, 1 Jun 2012 18:43:09 -0400 Keep-Alive:timeout=15, max=100 Pragma: Server:Apache Vary:Accept-Encoding mod_cache config is as follows: CacheRoot /var/cache/apache2/ CacheDirLevels 3 CacheDirLength 2 CacheEnable disk /foo What is getting in the way of mod_cache doing its job of caching?

• Server 2003 Terminal Services Printers not redirecting, no sessions created.

  - by mikerdz

  Ok, odd scenario on a Windows Server 2003 Server Standard running as Terminal Server. Friday, installed 2 new Windows 7 machines to replace older XP machines. After adding these machines and their local printers, none of the otehr 16 Windows 7 machines can redirect printing to the server. I have checked Global Policy on domain controller, nothing is being blocked. In Terminal Services Manager, the client settings are set to User Client Settings. On RDP client, port redirection is enabled. I have tried disabling the Use Client Settings option and manually selected the options for print redirection and default printer connection, but still does not work. After some reaserching, I found this MS article: http://support.microsoft.com/kb/2492632 I went ahead and added the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\fEnablePrintRDR DWORD that the article references and set it to "1" to enable the option. I restarted the server, but still would not print. I am getting quite desperate with this issue because nothing seems to have changed when installing the two new clients and printers. I uninstalled the print drivers for the printers from the server. I have even gone as far as connecting each of the printers manually via UPD (\computername\printer) but even thought it works, it prints awfully slow. Please help!!!!
