• 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. I have gone 2 months without a BSOD, then I have gone a week with 10+ without changing what I am doing. This is my system: Windows 7 Professional 64-bit Gigabyte GA-890GPA-UD3H AMD Phenom II x6 1090T Processor 3.2GHz 8GB Ram(4X 2GB) Radeon HD 7850 2TB HDD Thermaltake 500W PSU I'm not sure about what the BSOD says, it just counts to 100 by 5's then restarts the computer. It happens fast and I have tried to get a picture before but to no avail.

• Problems starting autossh on boot [ubuntu]

  - by Ken

  I'm trying to automatically start an SSH tunnel to my server on boot from a ubuntu box. I have an ubuntu box that's mounted on an 18-wheeler and is networked behind an air card. The box hosts a mysql database that i'm trying to have replicated when the aircard is connected. As I can never be sure of my IP and how many or which routers I'm behind I'm connected to my replication server with an SSH tunnel. I got that working using the following command: ssh -R 3307:localhost:3307 [email protected] Now I'd like that to start whenever the box is, and be alive all the time, so I installed auto-ssh and setup this little script: ID=xkenneth HOST=erdosmiller.com AUTOSSH_POLL=15 AUTOSSH_PORT=20000 AUTOSSH_GATETIME=30 AUTOSSH_DEBUG=yes AUTOSSH_PATH=/usr/bin/ssh export AUTOSSH_POLL AUTOSSH_DEBUG AUTOSSH_PATH AUTOSSH_GATETIME AUTOSSH_PORT autossh -2 -fN -M 20000 -R 3307:localhost:3306 ${ID}@${HOST} I've tried putting this scrip in /etc/init.d/ and using a post-up command in /etc/network/interfaces as well as putting it in /etc/network/if-up.d/. In both situations the script starts on boot, but the tunnel doesn't appear to be correctly established. The script works when run manually.

• Turning Google Apps mail inbox into Support Ticket System

  - by Saif Bechan

  I have an account at Google apps and most of my email is done trough Gmail. Now I just manually respond to support email. I was wondering if there is an easy way using filters and auto responders to create a support ticket system. I think something like this would be great, but is it possible: Gmail has to make a unique ID for every email that comes in. After that all the other incoming mails should be grouped using that unique ID and not grouped by email. Something like that, or are there things I am not taking into account. I really don't want to use separate software for this, because I think with some small configurations this can do the trick quite well. Or are there some free apps on the marketplace that do this already. I have searched for this but cannot find any. Sorry if this is not an SF question. I really didn't know which is the best fit for this question. This can be migrated to anywhere if someone things it would be answered better there.

• Debian network bridge configuration - /etc/network/interfaces

  - by Mathias

  I'm running a Lenny Xen dom0 hosting multiple virtual machines in a routed IP setup. To get an additional private subnet, I created the bridge xenbr0 in the dom0 with the following commands: brctl addbr xenbr0 ifconfig xenbr0 10.0.0.1 netmask 255.255.255.0 ifconfig xenbr0 up This works as expected, and domU interfaces are added to the bridge by Xen on VM start. My only problem is: how the heck do i specify this configuration in /etc/network/interfaces that it remains permanent and the bridge is available after a reboot? I tried the following config as found on a lot of tutorials: auto xenbr0 iface xenbr0 inet static address 10.0.0.1 netmask 255.255.255.0 network 10.0.0.0 broadcast 10.0.0.255 bridge_stp no I get 2 different errors, depending on if the bridge already exists or not. If it doesn't exist: root@dom0:~# brctl show bridge name bridge id STP enabled interfaces root@dom0:~# /etc/init.d/networking restart Reconfiguring network interfaces...if-up.d/mountnfs[eth0]: waiting for interface xenbr0 before doing NFS mounts (warning). SIOCSIFADDR: No such device xenbr0: ERROR while getting interface flags: No such device SIOCSIFNETMASK: No such device SIOCSIFBRDADDR: No such device xenbr0: ERROR while getting interface flags: No such device xenbr0: ERROR while getting interface flags: No such device Failed to bring up xenbr0. done. And if it exists: root@dom0:~# brctl show bridge name bridge id STP enabled interfaces xenbr0 8000.000000000000 no root@dom0:~# /etc/init.d/networking restart Reconfiguring network interfaces...if-up.d/mountnfs[eth0]: waiting for interface xenbr0 before doing NFS mounts (warning). RTNETLINK answers: File exists Failed to bring up xenbr0. done. Could anyone point me in the right direction please? The bridge works fine when created manually, i just need the right config file entries. The most tutorials I found add some devices to the bridge in the config, is that maybe the problem why it is not working? I don't have any interfaces I want to add to the bridge on creation as they get added later on VM start... Thanks, Mathias

• Apache 2.4, Ubuntu 12.04 Forbidden Errors

  - by tubaguy50035

  I just installed Apache 2.4 today, and I'm having some issues getting vhost configuration to work correctly. Below is the vhost conf <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot /hosting/Client/site.com/www ServerName site.com ServerAlias www.site.com <Directory "/hosting/Client/site.com/www"> Options +Indexes +FollowSymLinks Order allow,deny Allow from all </Directory> DirectoryIndex index.html </VirtualHost> There is an index.html file in /hosting/Client/site.com/www. When I go to the site, I receive a 403 forbidden error. The www-data group is the group on the www folder, which I've already given all permissions (r/w/x). I'm really at a loss as to why this is happening. Any thoughts? If I remove the vhost and go straight to the IP address, I get the default, "It works!" page. So I know that it's working. The error log says "client denied by server configuration". apache2ctl -S dump: nick@server:~$ apache2ctl -S /usr/sbin/apache2ctl: 87: ulimit: error setting limit (Operation not permitted) VirtualHost configuration: *:80 is a NameVirtualHost default server site.com (/etc/apache2/sites-enabled/site.com.conf:1) port 80 namevhost site.com (/etc/apache2/sites-enabled/site.com.conf:1) alias www.site.com port 80 namevhost site.com (/etc/apache2/sites-enabled/site.com.conf:1) alias www.site.com ServerRoot: "/etc/apache2" Main DocumentRoot: "/var/www" Main ErrorLog: "/var/log/apache2/error.log" Mutex watchdog-callback: using_defaults Mutex default: dir="/var/lock/apache2" mechanism=fcntl Mutex mpm-accept: using_defaults PidFile: "/var/run/apache2.pid" Define: DUMP_VHOSTS Define: DUMP_RUN_CFG Define: ENALBLE_USR_LIB_CGI_BIN User: name="www-data" id=33 not_used Group: name="www-data" id=33 not_used Ouput of namei -mo /hosting/Client/site/www/index.html f: /hosting/Client/site.com/www/index.html drwxr-xr-x root root / drwxr-xr-x root root hosting drwxr-xr-x root root Client drwxr-xr-x nick www-data site.com drwxr-xr-x nick www-data www -rw-rwxr-x nick www-data index.html

• How to troubleshoot Hyper-V VSS writer causing backup failure on Server 2008 R2

  - by Tim Anderson

  I have a Windows Server 2008 R2 machine running Hyper-V. Backups using Windows Server Backup fail with the error: The backup operation that started at '?2011?-?01?-?02T10:37:01.230000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348129'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved. I have traced this to a problem with the Hyper-V VSS writer. vssadmin list writers reports: Writer name: 'Microsoft Hyper-V VSS Writer' Writer Id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de} Writer Instance Id: {fcf0dd79-d282-4465-88ae-7b6857e055c2} State: [8] Failed Last error: Inconsistent shadow copy However I can't get any further. A few relevant facts: I get the error even if all the VMs are shut down If I disable the Hyper-V VSS Writer by stopping the Hyper-V Management Service backup completes OK There are no errors in the Hyper-V-VMMS application log I tried to set tracing for VSS but can't get any output for some reason. I set the correct registry entries but no trace log is generated. Tim

• SSH login very slow on OS X Leopard

  - by acjohnson55

  My SSH sessions take a very long time to initiate. This applies for logins with and without passwords, interactive and non-interactive. I have tried setting 'GSSAPIAuthentication no' and 'IPQoS 0x00' on the client side, and 'UseDNS no' on the server side, but no dice. I'm really stumped and frustrated. The worst part is that it SFTP takes forever to establish connections too, making file transfer much longer than it would be otherwise. I thought the problem might be something with PAM, because of where the hang is in the sshd log below, so I tried commenting out each line one-by-one in the /etc/pam.d/sshd file. Some caused login to be impossible, some had no apparent effect. I can't really tell if PAM is stalling for other services, but I can say that su'ing into my account from another account with 'su -l' has no apparent delay. I tried creating a new user account, just to see if there was something wrong with my existing account, and the same problem persisted. Any ideas of what's going on?

• ASUS EAH5450 Graphics Card (ATI Radeon HD5450 - 1 GB DDR3) on Windows 2003? Anybody got it to work?

  - by JJarava

  Hi all! I've just bought an ASUS EAH5450 Graphics Card (ATI Radeon HD5450, 1 GB DDR3) for my main system, but I haven't been able to make it work under Windows 2003 (my OS in that system). When I plugged the card, I got a couple of "installing drivers" prompt for things such as "ATI High Definition Audio Device" that got themselves sorted out of the Internet, and then a "Standard VGA Graphics Adapter". The CD that came with the card installs something called "ATI Catalyst Install Manager" and .net 2.0, but no drivers. I've downloaded the latest (WinXP 32bits) drivers from ATI, and the experience is the same: I don't get any drivers installed. My Motherboard is an ASUS A8N-SLI with nVidia nForce 4 chipset (for an Athlon 64X2, somewhat old), but my previous card was an ATi Radeon X700, so it's been working with ATI cards before. On POST, during boot I see a "Display Card" Device (Vendor ID 1002-68F9-0300) and a "Multimedia Device" (1002-AA68-0403), and when viewing the properties of the "Standard VGA", they match the device ID. Any hints? I'd really hate having to get rid of the card, and I'm sure it's not that strange what I'm trying to do...

• SharePoint Business Connectivity Services (BCS) Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'

  - by g18c

  I am running SharePoint 2010 with SQL 2012, I am trying to get Business Connectivity Services (BCS) running but I am facing a double-hope authentication issue. Everytime I try to connect to the external BCS list created in SharePoint designer, I get the error Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. In the event viewer on the SQL server I see a login failure for an anonymous user from the SP server IP address. Background information below: I have enabled Kerberos under SharePoint Central admin. I have the following AD domain accounts: SP_Farm - main website pool SP_Services - for SharePoint services (including BCS) SQL_Engine - SQL database engine I then created the following with SetSPN: SetSPN -S http/intranet mydomain\SP_Farm SetSPN -S http/intranet.mydomain.local mydomain\SP_Farm SetSPN -S SPSvc/SPS mydomain\SP_Farm SetSPN -S MSSQLSvc/SQL1 mydomain\SQL_DatabaseEngine SetSPN -S MSSQLSvc/SQL1.mydomain.local mydomain\SQL_DatabaseEngine SetSPN -S MSSQLSvc/SQL1:1433 mydomain\SQL_DatabaseEngine SetSPN -S MSSQLSvc/SQL1.mydomain.local:1433 mydomain\SQL_DatabaseEngine I then delegated the AD accounts for any authentication protocol to the following: SP_Farm - SP_Farm (http service type, intranet) SP_Farm - SQL_DatabaseEngine (MSSQLSvc, sql1) SP_Service - SP_Service (SPSvc) SP_Service - SQL_DatabaseEngine (MSSQLSvc, sql1) I have also checked the WFE is being logged on to with Kerberos, with the WFE server event log showing event ID 4624 with Kerberos authentication, this is OK. The SQL is also showing connections authenticated as Kerberos from the WFE with the following query: Select s.session_id, s.login_name, s.host_name, c.auth_scheme from sys.dm_exec_connections c inner join sys.dm_exec_sessions s on c.session_id = s.session_id Despite the above, credentials are not passed from the client through the SharePoint server to the SQL server, only the anonymous account is used. I get the following error in the WFE server for 'BusinessData' ID 8080: Could not open connection using 'data source=sql1.mydomain.local;initial catalog=MSCRM;integrated security=SSPI;pooling=true;persist security info=false' in App Domain '/LM/W3SVC/1848937658/ROOT-1-129922939694071446'. The full exception text is: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. If I set a username and password with the Secure Store Service and set the external list to use the impersonated credentials, the list works. Any ideas what I have missed and what can be tried next?

• How do I run a stable Windows XP kvm guest on Ubuntu 10.04?

  - by Jean-Paul Calderone

  I have three Windows XP guests running on a recently upgraded 64-bit Ubuntu 10.04 system. Occasionally (on the order of once every few days), one of the guests will become non-responsive and the kvm process on the host which is running that guest will start consuming 100% CPU. It will continue to do so until it is killed. When restarted, it will be fine for a while, and then the issue repeats. The kvm command line used to run all three guests is this: /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 1024 -smp 1 -name bigdog21vmxp1 \ -uuid ea47ff84-125b-16f7-9a4d-a6d0d8bab46a \ -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/bigdog21vmxp1.monitor,server,nowait \ -monitor chardev:monitor \ -localtime \ -boot c \ -drive file=/var/lib/libvirt/images/windowsxp-1.qcow2,if=ide,index=0,boot=on,format=qcow2 \ -net nic,macaddr=54:52:00:02:06:0e,vlan=0,name=nic.0 \ -net tap,fd=58,vlan=0,name=tap.0 \ -chardev pty,id=serial0 \ -serial chardev:serial0 \ -parallel none \ -usb \ -usbdevice tablet \ -vnc 127.0.0.1:1 \ -k en-us \ -vga cirrus \ -soundhw es1370 Why do the systems misbehave this way sometimes? And what configuration can I change in order to fix it? Or, if the problem is due to a bug in kvm, what is the process for isolating a kvm failure so that the developers have a chance of fixing it?

• How to Programmatically Split Data Using VBA Using Specific Logic

  - by Charlene

  This is an addition to my previous post here. The code that was previously supplied to me worked like a charm, but I am having issues modifying it adding some additional logic. I am creating a macro in VBA to do the following. I have raw order data that I need to transform based on some logic. Raw Data: order-id product-num date buyer-name prod-name qty-purc sales-tax freight order-st 0000000000-00 10000000000000 5/29/2014 John Doe Product 0 1 1.00 1.50 GA 0000000000-00 10000000000001 5/29/2014 John Doe Product 1 2 1.00 1.50 GA 0000000000-00 10000000000002 5/29/2014 John Doe Product 2 1 1.00 2.00 GA 0000000000-01 10000000000002 5/30/2014 Jane Doe Product 2 1 0.00 0.00 PA 0000000000-01 10000000000003 5/30/2014 Jane Doe Product 3 1 0.00 0.00 PA Desired Outcome: HDR 0000000000-00 John Doe 5/29/2014 CHG Tax 3.00 CHG Freight 5.00 ITM 10000000000000 Product 0 1 ITM 10000000000001 Product 1 2 ITM 10000000000002 Product 2 1 HDR 0000000000-01 Jane Doe 5/30/2014 ITM 10000000000002 Product 2 1 ITM 10000000000003 Product 3 1 The "CHG" rows are created based on the following logic; if the order-st is CA or GA, add the total of sales-tax and freight for each of the rows with the same order-id. If the order-st is NOT CA or GA, no CHG rows should be created. Any help would be appreciated - let me know if I left any details out!

• How to get gigabit network speeds on Windows XP?

  - by JB

  We've just installed gigabit switches at work, and things on the Linux side are going well. Our linux boxes, which use a Intel Corporation 82566DM-2 Gigabit nic (according to lspci), consistently get over 900 mbits/sec: iperf -c ipserver ------------------------------------------------------------ Client connecting to ipserver, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.40.9 port 39823 connected with 192.168.1.115 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 1.08 GBytes 929 Mbits/sec We have a bunch of Windows XP 64-bit machines that use Broadcom NetXtreme 57xx cards. I spent around a day trying to get equivalent speeds on them, but couldn't get above 200 Mbits/sec. I noticed the Windows iperf tests said that the TCP window size was 8 Kb by default (as opposed to 16 Kb on Linux, so I modified my test to reflect that. Still no love. I went to Broadcom's site, downloaded the latest drivers for the card and installed. Still no love. However, finally, I tried a 64 Kb window size with the new drivers, and finally an improvement! $ iperf -c ipserver -w64k ------------------------------------------------------------ Client connecting to ipserver, TCP port 5001 TCP window size: 64.0 KByte ------------------------------------------------------------ [ 3] local 192.168.40.214 port 1848 connected with 192.168.1.115 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 933 MBytes 782 Mbits/sec Much better, but still not really taking advantage of the full capabilities of the network. If the Linux box can reach 950 Mbits/sec consistently, this box should be able to as well. Also, if you're wondering about the medium, this is over the same cable...I'm switching back and forth. Any suggestion or ideas would be really welcome. Thanks!

• Ubuntu 13.04 to 13.10: Filesystem check or mount failed [migrated]

  - by SamHuckaby

  I attempted to upgrade from Ubuntu 13.04 to 13.10 today, and mid upgrade the system started flaking out, and eventually locked up entirely. I was forced to restart the computer, and am now unable to get the computer to boot up at all. When I boot currently, it takes me to the GRUB menu, and I can choose to boot normally, or boot in an older version. I have tried several things, which I list below, but no matter what, when I try to finish booting into Ubuntu, I receive the following error: Filesystem check or mount failed. A maintenance shell will now be started. CONTROL-D will terminate this shell and continue booting after re-trying filesystems. Any further errors will be ignored root@ubuntu-computername:~# I have fun fsck -f and everything appears correct, no errors are reported. and it passes all 5 checks. If I run fdisk -l then I get the following information: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes Disk identifier: 0x00010824 Device Boot Start End Blocks Id System /dev/sda1 * 2048 608456703 304227328 83 Linux /dev/sda2 608458750 625141759 8341505 5 Extended Partition 2 does not start on physical sector boundary. /dev/sda5 608458752 625141759 8341504 82 Linux swap / Solaris Disk /dev/sdb: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0fb4b7e8 Device Boot Start End Blocks Id System /dev/sdb1 8192 625139711 312565760 7 HPFS/NTFS/exFAT I am considering just installing a new OS on the other disk, that currently has nothing on it, and then just attempting to scrape my data off the old disk (thankfully I didn't encrypt the files).

• Microsoft Arc Mouse OS X

  - by meepz

  I recently bought a new Mac Book Pro with Mountain Lion 10.8 on it. The only portable mouse I have is my Microsoft Arc Mouse. I wanted to use it with the laptop so I installed the IntelliPoint 8.2 for Mac from Microsofts website. According to their website, this driver is for OS X 10.4-10.7. Now I thought that wouldnt be too much of an issue but unfortunately for me, the driver installs fine and the mouse is detected but I get no movement and when I click the buttons nothing happens. I took the mouse with me on a business trip to EU and before I left I checked if the mouse worked with my desktop which is running Windows 7 and it worked without any hiccups. I'm not too sure where the OS differs from 10.7 to 10.8. I found an article online but it doesn't pertain to my mouse, although it could be of assistance. I have tried my version of their adjustment but I am not too knowledgable on low level hardware/software modifications so I may have done it wrong. heres the link: http://refluxions.wordpress.com/2008/08/18/mac-os-x-mouse-madnessfixed/ I get the following details when I check mouse info in the IntelliPoint preferences pane: The following Microsoft mouse devices are currently connected to your Macintosh driven by the Intellipoint software. Arc Mouse Vendor name: Microsoft Product name: Microsoft AE 2.4GHz Transceiver 5.0 Vendor ID: 045E Product ID: 074F Device version: 0140 if anyone has any suggestions on how to fix this it would be greatly appreciated! I love the mouse and im here in EU for another two weeks. Thanks

  I have a Dell PowerEdge 2950 with this card: RAID bus controller [0104]: Dell PowerEdge Expandable RAID controller 5 [1028:0015] and six disks in a RAID-10.

  When I send a test message from my mail server to my @bellsouth.net email, The postfix log shows it was sent OK, but the message never arrives in my bellsouth inbox. Shouldn't I get a failure notice or a bounce if At&T is blocking the messages? I'm trying to troubleshoot why some customers aren't getting emails, but if there's nothing in mail.log to say the message is rejected, how do I know which messages were delivered successfully? The log shows: Feb 27 09:02:36 MyHOSTNAME postfix/pickup[26175]: D53A72713E5: uid=0 from=<root> Feb 27 09:02:36 MyHOSTNAME postfix/cleanup[26487]: D53A72713E5: message-id=<[email protected]> Feb 27 09:02:36 MyHOSTNAME postfix/qmgr[5595]: D53A72713E5: from=<[email protected]>, size=878, nrcpt=1 (queue active) Feb 27 09:02:37 MyHOSTNAME postfix/smtp[26490]: D53A72713E5: to=<[email protected]>, relay=gateway-f1.isp.att.net[204.127.217.16]:25, delay=0.57, delays=0.11/0.03/0.23/0.19, dsn=2.0.0, status=sent (250 ok ; id=20120227140036M0700qer4ne) Feb 27 09:02:37 MyHOSTNAME postfix/qmgr[5595]: D53A72713E5: removed The AT&T server accepted the message, right? I happen to have an At&T/Bellsouth email, but I don't have an account with every ISP we send to. I need some way of knowing if a message is getting to its destination or not. Is there any setting in my main.cf file that would affect whether or not we get reject/bounce notices?

• Where is my CPU usage going?

  - by Josh

  My Ubuntu 10.04 Lucid virtual machine is saying it's at 100% CPU usage... but all I'm running is Thunderbird. According to top, CPU usage should be ~25.9%... How do I interpret this conflicting output from top? top - 13:55:26 up 3:35, 4 users, load average: 3.03, 2.59, 2.48 Tasks: 178 total, 1 running, 177 sleeping, 0 stopped, 0 zombie Cpu(s): 16.0%us, 79.7%sy, 0.0%ni, 0.0%id, 0.0%wa, 1.3%hi, 3.0%si, 0.0%st Mem: 509364k total, 479108k used, 30256k free, 3092k buffers Swap: 2096440k total, 58380k used, 2038060k free, 225116k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 7708 jnet 20 0 480m 109m 17m S 18.4 22.1 21:59.14 thunderbird-bin 4615 jnet 20 0 5488 1268 1040 S 2.3 0.2 5:00.03 nx-rootless-ses 7124 jnet 20 0 56688 27m 4812 S 2.0 5.5 6:35.09 nxagent 6724 nx 20 0 9628 1400 636 S 1.6 0.3 3:26.59 sshd 30106 root 20 0 2544 1236 908 R 0.7 0.2 0:00.33 top 19 root 20 0 0 0 0 S 0.3 0.0 0:22.45 ata/0 38 root 20 0 0 0 0 S 0.3 0.0 0:05.53 scsi_eh_1 345 root 20 0 0 0 0 S 0.3 0.0 0:04.72 kjournald 1719 root 20 0 3260 1192 944 S 0.3 0.2 0:17.36 vmware-guestd 1 root 20 0 2804 1356 940 S 0.0 0.3 0:01.99 init 2 root 20 0 0 0 0 S 0.0 0.0 0:00.01 kthreadd 3 root RT 0 0 0 0 S 0.0 0.0 0:00.00 migration/0 4 root 20 0 0 0 0 S 0.0 0.0 0:00.15 ksoftirqd/0 5 root RT 0 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 ...

• Very slow connection to xserve via afp or smb

  - by Mhoffman13

  Help. File transfer and connection speed to our Xserve are painfully slow from newly purchased iMacs. The Xserve is only used as a file server, its running 10.4.11. The problem seems to be only happening on brand new iMacs running 10.6.3. When connected either over afp or smb copying files is many times slower than usual. Other machines on the network running either 10.4 or 10.5 have a normal connection speed. To try to rule out OS incompatibility I connected the new iMac running 10.6 to another computer running 10.4 over the network. The file transfer speed was fast as normal. So it seems the problems lies with the X serve (maybe). The afp logs either access or error don't show anything unusual. One thing that did look different was when the imac was connected to the Xserve the user had its id listed as its IP address. The other machines connected, had the id of broadcasthost. I also noticed that when connected from the new iMac I can only see one of the mirrors. When any other computer connects both mirrors are shown. Tried a restart of the Xserve but the problem persists. Thanks in advance for any advice

• OpenBSD logins via SSH seem to be ignoring my configured radius server

  - by Steve Kemp

  I've installed and configured a radius server upon my localhost - it is delegating auth to a remote LDAP server. Initially things look good: I can test via the console: # export user=skemp # export pass=xxx # radtest $user $pass localhost 1812 $secret Sending Access-Request of id 185 to 127.0.0.1 port 1812 User-Name = "skemp" User-Password = "xxx" NAS-IP-Address = 192.168.1.168 NAS-Port = 1812 rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=185, Similarly I can use the login tool to do the same thing: bash-4.0# /usr/libexec/auth/login_radius -d -s login $user radius Password: $pass authorize However remote logins via SSH are failing, and so are invokations of "login" started by root. Looking at /var/log/radiusd.log I see no actual log of success/failure which I do see when using either of the previous tools. Instead sshd is just logging: sshd[23938]: Failed publickey for skemp from 192.168.1.9 sshd[23938]: Failed keyboard-interactive for skemp from 192.168.1.9 port 36259 ssh2 sshd[23938]: Failed password for skemp from 192.168.1.9 port 36259 ssh2 In /etc/login.conf I have this: # Default allowed authentication styles auth-defaults:auth=radius: ... radius:\ :auth=radius:\ :radius-server=localhost:\ :radius-port=1812:\ :radius-timeout=1:\ :radius-retries=5:

• Abysmal transfer speeds on gigabit network

  - by Vegard Larsen

  I am having trouble getting my Gigabit network to work properly between my desktop computer and my Windows Home Server. When copying files to my server (connected through my switch), I am seeing file transfer speeds of below 10MB/s, sometimes even below 1MB/s. The machine configurations are: Desktop Intel Core 2 Quad Q6600 Windows 7 Ultimate x64 2x WD Green 1TB drives in striped RAID 4GB RAM AB9 QuadGT motherboard Realtek RTL8810SC network adapter Windows Home Server AMD Athlon 64 X2 4GB RAM 6x WD Green 1,5TB drives in storage pool Gigabyte GA-MA78GM-S2H motherboard Realtek 8111C network adapter Switch dLink Green DGS-1008D 8-port Both machines report being connected at 1Gbps. The switch lights up with green lights for those two ports, indicating 1Gbps. When connecting the machines through the switch, I am seeing insanely low speeds from WHS to the desktop measured with iperf: 10Kbits/sec (WHS is running iperf -c, desktop is iperf -s). Using iperf the other way (WHS is iperf -s, desktop iperf -c) speeds are also bad (~20Mbits/sec). Connecting the machines directly with a patch cable, I see much higher speeds when connecting from desktop to WHS (~300 Mbits/sec), but still around 10Kbits/sec when connecting from WHS to the desktop. File transfer speeds are also much quicker (both directions). Log from desktop for iperf connection from WHS (through switch): C:\temp>iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 8.00 KByte (default) ------------------------------------------------------------ [248] local 192.168.1.32 port 5001 connected with 192.168.1.20 port 3227 [ ID] Interval Transfer Bandwidth [248] 0.0-18.5 sec 24.0 KBytes 10.6 Kbits/sec Log from desktop for iperf connection to WHS (through switch): C:\temp>iperf -c 192.168.1.20 ------------------------------------------------------------ Client connecting to 192.168.1.20, TCP port 5001 TCP window size: 8.00 KByte (default) ------------------------------------------------------------ [148] local 192.168.1.32 port 57012 connected with 192.168.1.20 port 5001 [ ID] Interval Transfer Bandwidth [148] 0.0-10.3 sec 28.5 MBytes 23.3 Mbits/sec What is going on here? Unfortunately I don't have any other gigabit-capable devices to try with.

• Unable to logon using terminal server connection

  - by satch

  I have several W2K3 SP2 servers, admin TS enabled. I discovered this morning, I was unable to logon into some of them. I've a couple of Citrix servers in different farms, a SAP (IA64) app server and a cvs server. All of them show same sympthoms; remote connections are refused. I've been able to logon locally, and terminal server service is up, there are no users (so connections are not depleted). There are no errors in log in most servers. One of the Citrix ones, reported following errors: Event ID 50 Source TermDD Type Error Description The RDP protocol component X.224 detected an error in the protocol stream and has disconnected the client. and Event ID 1006 Source TermService Type Error Description The terminal server received large number of incomplete connections. The system may be under attack. Anyway, I suppose these errors appear because server isn't working, and Citrix users try to logon massively. (I nmap'ed server and port seems up). I've solved this problem rebooting before, but with so many servers affected it seems like a crappy workaround. Any idea about troubleshooting it properly? Thanks in advance
