• Server hang - data loss on reboot, post mortem analysis

  - by rovangju

  A development server I'm responsible for (ext3 on raid 5 w/Debian Squeeze) froze up over the weekend and I was forced to reset it, as in unresponsive from KVM/physical keyboard access, no eth devices responding, etc. Not even the backup process ran (Figures, the one time I don't check for confirmation) So after the reset, it turns out that every trace of disk IO activity that should have happened for a period of ~24H is completely gone. The log files have a big gap in the dates and times. As if the writes were never committed to disk, no processes seemed to have run. Luckily it was a weekend and nothing of value would have been lost and I don't suspect a hack. What can I do in post mortem to this event - to prevent it from ever happening again? I've seen this happen before on a completely different machine running FreeBSD. I am rounding up the disk checking tools right now - but there must be more going on! Mount options: /dev/sda1 on / type ext3 (rw,errors=remount-ro) Kernel: Linux dev 2.6.32-5-686-bigmem Disk/Inodes: 13%/3%

• exim4 to relay emails

  - by Matthieu

  I have exim4 installed on a Linux box. The basics work fine and I can send email from that machine without any problem to whatever email address. I also have a printer/scanner which is capable to send scans as emails. It needs an SMTP gateway to be able to do that. So I give the IP address of that Linux box, changed the configuration a little bit but still cannot get it to work. After I run dpkg-reconfigure exim4-config, here is what I get in /etc/exim4/update-exim4.conf.conf : dc_eximconfig_configtype='internet' dc_other_hostnames='' dc_local_interfaces='127.0.0.1;192.168.2.2' dc_readhost='' dc_relay_domains='mycompanyemail.com' dc_minimaldns='false' dc_relay_nets='192.168.2.0/24' dc_smarthost='' CFILEMODE='644' dc_use_split_config='false' dc_hide_mailname='' dc_mailname_in_oh='true' dc_localdelivery='mail_spool' My problem is that with this configuration, I can only send to emails @mycompanyemail.com... It says I can use wildcard, but when I do that, the '*' is replaced by whatever filename is in the directory where I run all that. How can I configure it to be able to send emails with any domain ? Or am I doing it wrong ? EDIT : here is the part of the log that's causing trouble : 2011-08-03 16:28:18 H=(NPI2D389C) [192.168.2.20] F=<[email protected]> rejected RCPT <[email protected]>: relay not permitted The first part ([email protected]) does not matter. I changed the email address. The point is that if this email is @mycompanyemail.com then everything works fine. Anything else does not work. I could add gmail.com, but I am looking to have any domain working...

• Apache 403 after configuring varnish

  - by w0rldart

  I just don't know where else to look and what else to do.

• Sendmail in Nexenta core 3.0.1

  - by maximdim

  I'm trying to setup sendmail in Nexenta core 3.0.1 (Solaris based OS). All I want is to be able to send emails from that host - like notifications about failures, cron jobs output etc. Initially Nexenta core doesn't have sendmail so here is what I've done: apt-get install sunwsndmu Now there is a sendmail in /usr/sbin/sendmail. When I try to send email from command line: $mail maxim test . It doesn't give me any error but in log file I see: Dec 20 12:41:08 nas sendmail[12295]: [ID 801593 mail.info] oBKHf8u7012295: from=maxim, size=107, class=0, nrcpts=1, msgid=<201012201741.oBKHf8u7012295@nas>, relay=maxim@localhost Dec 20 12:41:08 nas sendmail[12295]: [ID 801593 mail.info] oBKHf8u7012295: to=maxim, ctladdr=maxim (1000/10), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30107, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1] So I guess I need to have SMTP service running. How do I do that in Nexenta? svcs -a | grep sendmail doesn't return anything and # svcadm enable sendmail svcadm: Pattern 'sendmail' doesn't match any instances I'm not married to sendmail so if there are easier ways to achieve y goal I'm open to suggestions as well. Thanks,

• Windows Server 2003 with Apache and IIS causing random faulting and performance issues with Apache?

  - by contrebis

  I'm trying to fix a problem on a Windows Server 2003 SE install which is running IIS6 and Apache webserver (with PHP and MySQL). IIS sites are bound to one IP, Apache to the other. Everything seemed fine till the other IP address was installed to allow a webservice to run under IIS. Symptoms: Apache now responds very slowly, even requests for static files (often 30 seconds or more) Sporadic errors are appearing in the event logs like: Faulting application httpd.exe, version 2.2.14.0, faulting module php5ts.dll, version 5.2.13.13, fault address 0x000ac14f. I've double-checked the config files, taken account of this question/answer http://serverfault.com/questions/51230/running-iis-and-apache-on-the-same-windows-server, upped the Apache log level to debug, run TCPView to check for conflicting bindings, upgraded to latest Apache/PHP versions but still no success or indication of a cause. Any suggestions on where to look, or debugging tips would be gratefully received. I'm a web programmer so not so familiar with Windows Server admin or details of the networking stack. Running PHP under IIS is not an option and hosting on another server is non-ideal.

• rsync not copying hard links

  - by A.Ellett

  I have two computers (both MacBook Airs) for which I sync one directory tree in both, but not the entire hard drive or any other directories. Let's say on computer A the directory is /Users/aellett/projects Let's say on computer B the directory is /Users/bellett/projects Generally, I'll log into computer B and then remotely connect to computer A as user 'aellett'. As super user I sync the two project directories as follows: rsync -av /Volumes/aellett/projects/ /Users/bellett/projects/ and this works as expected. On both computers I have another file letter.txt in a different directory which is not getting synced. Let's say on computer A the file is found in /Users/aellett/letters On computer B the file is found in /Users/bellett/correspondence Generally, I don't want to share what's not included in /Users/<username>/projects. But I do want to share this particular file. So on both computer I made a correspondence directory in projects. And then I made hard links as follows On computer A: ln /Users/aellett/letters/letter.txt /Users/aellett/projects/correspondence/letter.txt On computer B: ln /Users/bellett/correspondence/letter.txt /Users/aellett/projects/correspondence/letter.txt The next time I synced the two computers I did the following rsync -av -H /Volumes/aellett/projects/ /Users/bellett/projects/ When I checked on computer B, /Users/bellett/projects/correspondence/letter.txt was correctly synced. But, the hardlink to /Users/bellett/correspondence/letter.txt was no longer there. In other words, /Users/bellett/projects/correspondence/letter.txt was identical to /Users/aellett/projects/correspondence/letter.txt but it differed from /Users/bellett/correspondence/letter.txt. Since these two files were hard linked on both computers, I expected them to still have the hard link. Why are my hard links not being preserved?

• Mail server: can't connect via POP/IMAP

  - by MelkerOVan

  I've followed this guide on setting up a mail server on my dedicated server. I've been able to send mails from the php application I'm using and the linux commandline (using telnet, php, etc). The problem is that I cannot connect to the server via IMAP/POP which I've setup using Courier. I've tried using thunderbird but it complains that the username or password is wrong. I doubt it is the username/password but I don't know how to trouble shoot this. Edit: Here's the messages in mail.log: Jan 9 22:43:38 mail authdaemond: received auth request, service=imap, authtype=login Jan 9 22:43:38 mail authdaemond: authmysql: trying this module Jan 9 22:43:38 mail authdaemond: SQL query: SELECT id, crypt, "", uid, gid, home, "", "", name, "" FROM users WHERE id = '[email protected]' AND (enabled=1) Jan 9 22:43:38 mail authdaemond: password matches successfully Jan 9 22:43:38 mail authdaemond: authmysql: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/var/spool/mail/virtual, [email protected], fullname=peter, maildir=<null>, quota=<null>, options=<null> Jan 9 22:43:38 mail authdaemond: authmysql: clearpasswd=<null>, passwd=password Jan 9 22:43:38 mail authdaemond: Authenticated: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/var/spool/mail/virtual, [email protected], fullname=peter, maildir=<null>, quota=<null>, options=<null> Jan 9 22:43:38 mail authdaemond: Authenticated: clearpasswd=peter, passwd=password Jan 9 22:43:38 mail imapd: chdir Maildir: No such file or directory

• Can't pop3 from exchange server after a reboot

  - by BLAKE

  Last night I shutdown my Exchange 2003 Virtual Machine, I added a new VHD (For backups), and booted it again. Now I can't POP3 email from it with Outlook 2007. In Outlook I get the error: Task '[email protected] - Receiving' reported error (0x800CCC0F) : 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).' Does anybody know what is wrong? All I did was a reboot. I haven't formated the added disk. There are no weird errors in the event log. I can still send mail with Outlook over port 25. I can send and recieve mail with OWA. I can POP3 the mail to my phone (it take about 15 minutes after sending a message, but I do get it eventually). EDIT: The 'Microsoft Exchange POP3' Service says that it is started but if I stop it and try to start it again, it fails saying 'Could not start the Microsoft Exchange POP3 service on Local Computer. Error 1053: The service did not respond to the start or control request in a timely fashion.' I did some googling and someone on exchangefreaks.com said that if I use task manager to 'End Task' on inetinfo.exe, then I can start the POP3 service fine. Does anyone know what causes this problem? I am fine for now since I did get the Service started, but If it does this after every reboot...

• SQL Server restore a backup results in an error.

  - by Mario

  I have a database in dev (SQL Server 2005 on Windows Server 2008) that I need to move to prod (SQL Server 2000 on Windows Server 2003). My process is as follows: Login to dev, open SQL Server Management Studio Right click on the database | Tasks | Backup. Keep all default options (full backup etc.) Move .bak file locally to prod (no network drive), login to prod, open SQL Server Enterprise Manager. Right click Databases node | All Tasks | Restore database. Change Restore as database to reflect the same database name. Click radio button 'From device'. Click 'Select Devices' Click Restore from: Add..., browse to .bak file (small - only 6mb) Now I am ready to restore the database, so I click OK and get the following error: "The media family on device 'E:...bak' is incorrectly formed. SQL Server cannot process this media family. RESTORE DATABASE is terminating abnormally." This error is immediate. I have tried a few different variations of this - restoring the db to dev machine with a different db name and log file names (where it originated), creating an empty database with the same physical path to files before and trying to restore to that, making a few different .bak files and making sure they are verified before uploading them to prod. I know for a fact the directory for the .mdf and .ldf files exist on prod, though the files themselves don't exist. If, before I click OK to restore, go to the options tab instead I get the following error: Error 3241: The media family on device 'E:...bak' is incorrectly formed. SQL Server cannot process this media family. RESTORE FILELIST is terminating abnormally. Anyone have any bright ideas?

• Domino nchronos.exe multiple instances causing server to die, and Sametime problems

  - by Kevin

  I've had this problem for a few months now. I thought it started when I installed the Traveller software on the server to add ActiveSync support, but I removed that and the problem still persists. Basically new instances of "nchronos.exe" keeps spawning (and not ending), so over a period of a few days the server eventually gets drowned in nchronos.exe processes, stops responding and I need to kill Domino. My process count the last time was up at about 330, and when I killed it and restarted the Domino my process count went to 160. I'm running Domino 8.5.1 with Fix Pack 2. I don't know if it's relevant, but my Domino server was also acting as a Sametime server. At around the same time that nchronos started playing up sametime also stopped working. None of my users can connect to sametime and in the domino log it keeps telling me "stpolicy.exe" has terminated. I've googled for that and tried a few things, but nothing seems to make sametime work again. Any thoughts?? Cheers, Kevin

• IIS running but not serving content

  - by Kyle

  I have an internal dev server running Windows 2k8 R2 with the Web and FTP Server roles set up which won't serve any content at all. Trying to connect from another host via telnet yields 'connection failed': c:\>telnet devserver 80 Connecting To devserver...Could not open connection to the host, on port 80: Conn ect failed Using netstat -an | find "80" on the dev server returns no connections on port 80 (a few on 1801, etc) tcpview confirms this, listing no open connections on port 80. The following services related to the Web role are running: World Wide Web Publishing Service Application Host Helper Service Microsoft FTP Service (ftp connections to port 21 are granted) Windows Process Activation Service The default website bindings are: Type Host Name Port IP Address Binding Information http 80 * net.tcp 808:* net.pipe * net.msmq localhost msmq.formatname localhost When setting up a new application under the default site, the test function passes both connection/authorisation only if the 'connect as' user is local admin, otherwise the test errors with 'invalid application path'. At no point is the W3SVC service PID bound to port 80 (it is running and bound to 21 for ftp). There are no W3SVC log directory at c:\inetpub\logs\LogFiles\ (only FTPSVC2), and no HTTPERR directory at c:\windows\system32\ or c:\windows\system32\logfiles\. There do not appear to be any related errors in the event logs. I'd really appreciate any thoughts on be a good place dig into what's (not) going on here!

• ssh timeout issue connecting to an EC2 instance on OS X

  - by mamusr

  I am new to AWS and not a networking expert but curious to know more about it. I created a VPC with a public subnet only. Then i created an EC2 instance using an Ubuntu 14.04 64-bit pv AMI image (ami-e84d8480) as well generating the key pair needed to connect to it through ssh. I followed amazon's instructions to connect to an EC2 instance via ssh which did not work. Here is my attempted input and debug log: Running on OS X 10.9.4 user$ ssh -vvv -i key.pem [email protected] OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: /etc/ssh_config line 102: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to xxx.xxx.xxx.xxx [xxx.xxx.xxx.xxx] port 22. debug1: connect to address xxx.xxx.xxx.xxx port 22: Operation timed out ssh: connect to host xxx.xxx.xxx.xxx port 22: Operation timed out To attempt to resolve the issue: I enabled the SSH port. Tried different usernames other than ubuntu, like ec2-user and root. Initially set an inbound ssh rule in the security group to connect to only my ip address. When that did not work, i changed it to allow any ip to connect. But those actions did not fix the problem. Here are my guesses as to what i am missing in getting the EC2 instance connection to work. My etc/ssh_config file may be preventing the connection from taking place. I may have missed an important networking detail when setting up the VPC. I do not have a public ip address specified for the instance. I am connecting through the private ip address. My questions for the community: Am i going about it the wrong way connecting to the instance through the private ip address? if so, do i need to specify a public ip address for it to connect or some other method?

• Ubuntu 13.10 on Acer V5-472 with HD 4000

  - by Hyperboreus

  I have an Acer V5-472 with intel HD4000 graphics chipset and a built-in 1366*768 display. I have installed ubuntu 13.10 amd64 in legacy boot mode with an external monitor. Installation showed no problems, I can boot from HDD and log into my system. The internal display doesn't work and I have to use an external monitor. I have tried the following (found in other threads) to no avail: Setting grub option "acpi_backlight=vendor" or "acpi_osi=Linux" or both. Installing the intel HD drivers for Linux from their homepage. Running in circles, screaming and shouting. The internal display lights up (I can change the brightness with Fn-Left and Fn-Right) but that's all. When I boot, I get a purple splash screen and from then only the external monitor works. I read somewhere that this might be a problem with kernel 3.11? Has anybody ubuntu running on an Acer V5-472? Should I change ubuntu version or use 32-bit instead? In general, how can I get the internal display to work? Edit: The settings-display dialogue shows the internal display correctly with supported resolution of 1366.

• Unable to activate Windows XP

  - by Josh Kelley

  The latest round of Patch Tuesday updates left my Windows XP computer unbootable. ("Fatal System Error: The Windows Logon Process system process terminated unexpectedly.") After much messing around with the recovery console, an XP CD's repair mode, and manually copying registry files around, I have a system that can boot again. However, I overwrote my OEM XP installation's activation information while trying to run a retail XP CD's setup, so it needs reactivation. Here's my problem: I cannot activate it at all. I log in, Windows tells me I have to activate to continue, I click Yes, and absolutely nothing happens: no windows, no response to keyboard or mouse, no response to Ctrl-Alt-Del, nothing. Safe mode works, but I can't activate in safe mode (EDIT: not even safe mode with networking). I read a trick online of pressing [Windows Key]+U to bring up the Microsoft Narrator, and that works, but clicking its Microsoft Web Site link does nothing. My last attempt to resolve this was to reinstall Windows off of the OEM CD. Now I have two parallel Windows installations, both on the same hard drive, one with all of my stuff and no way to activate it, one fully activated with no usable programs. Any ideas? Any way to activate in safe mode? Any way to copy activation information from my activated installation to my unactivated installation (since they're both on the same hard drive)?

• Intel DriverInstall issue on HP ProLiant server DL580G5

  - by TomTom

  Given: A HP ProLiant server to be used for Hyper-V server (R 2) Problem: The server has a HP NC364T quad port card, which actually is an Intel 1000 Pro adapter. We are stuck getting this adapter properly working. We need to get it working with: 2 trunks of 2 ports each one of them fully vlan "aware" (without filtering anything - so that Hyper-V can do the VLAN filtering). So far we did: Install the server Install latest PSP. Problem here - tool does not work to set up teaming. We tried to install the latest ProWin pack from Intel - the drivers there are a LOT more current (26th of Marrch 2010, 9.13.41.0). The intalled driver (Microsoft) is ancient (march 2009, 9.13.4.10) A driver update fails both on command line (pnputil) as well as the PortLock device manager executable. No informatoin is provided. the ANS toolset can not create teams (fails with error - again, no reason provided), I know of no logs and the event log has no information either. Questions: What are the best drivers to use? How do we actually install them? How can we then set up teaming and how do we set up the VLAN behavior wanted?

• Tomcat web application intermittent freeze

  - by tinny

  I have a Grails web application (just a standard war file) deployed on a Ubuntu 10.10 server running on tomcat 6. My database is postgresql. The problem is that every so often (once or twice a day after inactivity) when I try to log into this web application it just freezes. I can navigate to the login page but when I try and login (first time the DB is hit, might be a clue..?) the application just freezes indefinitely, no 500 response code... the browser just waits and waits. I followed the instructions detailed here because the problem described sounded the same as mine. My GC logging showed no long running GC, all sub sec. When the application freezes a jmap heap output is... using parallel threads in the new generation. using thread-local object allocation.

• Why does ATI 5570 HD video card driver installation cause Windows 7 To Blue Screen?

  - by Mort

  This one is for the hive mind. I have a brand new Dell Optiplex 760 workstation with 4 gigabytes of RAM running Windows 7 Professional (32bit). This is a new box with nothing installed other than what was provided for directly by Dell. I installed a Saphire ATI PCI Express 5570 HD. Upon trying to install the 10.4 Catalyst drivers the system will blue screen. It blue screens during the hardware detection phase of the installation process. I have already performed the following trouble shooting steps: Changed system RAM Installed only 2 gigabytes of RAM Installed different versions of Catalyst drivers (10.4 - 9.12) Tried to install video only component of driver (vs entire Catalyst suite) Made sure Windows 7 was fully updated Flashed mother board BIOS to current version Removed and re-seated video card Contacted ATI Support (We all know how this went......) Verified supply outputting properly The blue screen error (via Windows BugCheck entry in event log) is a 0x000000CA and refers to a plug and play error most likely caused by a bad driver. The problem is that the driver installation process never gets far enough to actually install a driver. The resolution center in Windows provides a solution of installing the 10.4 Catalyst driver to resolve issue (which fails). Looking for some alternate views to resolve.

• Repairing inconsistent pages in database

  - by Raj

  We have a SQL 2000 DB. The server crashed due to Raid array failure. Now when we run DBCC CHECKDB, we get an error that there are 27 consistency errors in 9 pages. When we run DBCC PAGE on these pages, we get this: Msg 8939, Level 16, State 106, Line 1 Table error: Object ID 1397580017, index ID 2, page (1:8404521). Test (m_freeCnt == freeCnt) failed. Values are 2 and 19. Msg 8939, Level 16, State 108, Line 1 Table error: Object ID 1397580017, index ID 2, page (1:8404521). Test (emptySlotCnt == 0) failed. Values are 1 and 0. Since the indicated index is non-clustered and is created by a unique constarint that includes 2 columns, we tried dropping and recreating the index. This resulted in the following error: CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 2. Most significant primary key is '3280'. The statement has been terminated. However running Select var_id,result_on from tests group by var_id,result_on having count(*)>1 returns 0 rows. Here is what we are planning to do: Restore a pre-server crash copy of the DB and run DBCC CHECKDB If that returns clean, then restore again with no recovery Apply all subequent TLOG backups Stop production app, take a tail log backup and apply that too Drop prod DB and rename the freshly restored DB to make it prod Start prod app Could someone please punch holes in this approach? Maybe, suggest a different approach? What we need is minimum downtime. SQL 2000 DB Size 94 GB The table that has corrupt pages has 460 Million+ rows of data Thanks for the help. Raj

• How Could My Website Be Hacked

  - by Kiewic

  Hi! I wonder how this could happen. Someone delete my index.php files from all my domains and puts his own index.php files with the next message: Hacked by Z4i0n - Fatal Error - 2009 [Fatal Error Group Br] Site desfigurado por Z4i0n Somos: Elemento_pcx - s4r4d0 - Z4i0n - Belive Gr33tz: W4n73d - M4v3rick - Observing - MLK - l3nd4 - Soul_Fly 2009 My domain has many subdomains, but only the subdomains that can be accessed with an specific user were hacked, the rest weren't affected. I assumed that someone entered through SSH, because some of these subdomains are empty and Google doesn't know about them. But I checked the access log using the last command, but this didn't show any activity through SSH or FTP the day of the attack neither seven days before. Does anybody has an idea? I already changed my passwords. What do you recommend me to do? UPDATE My website is hosted at Dreamhost. I suppose they have the latest patches installed. But, while I was looking how they entered to my server, I found weird things. In one of my subdomains, there were many scripts for execute commands on the server, upload files, send mass emails and display compromising information. These files had been created since last December!! I have deleted those files and I'm looking for more malicious files. Maybe the security hold is an old and forgotten PHP application. This application has a file upload form protected by a password system based on sessions. One of the malicious scripts was in the uploads directory. This doesn't seem like an SQL Injection attack. Thanks for your help.

• Windows RDP cannot connect to x64 server from XP SP3+ [closed]

  - by Tom

  Hi all, I have a strange problem that I can't seem to find the answer to anywhere online. The issue has to do with using Windows RDP to connect to our servers. Here is what works: -XP/Vista client (any SPs) connecting to 32-bit Server 2003 machine -XP (SP2 and lower) client conecting to 64-bit Server 2003 machine Here is what does not work: - XP SP3+/Vista client connecting to 64-bit Server 2003 machine It appears that the issue is that XP SP3 and Vista clients cannot connect to x64 Server 2003 boxes. After entering the username/password, we get an error message saying the below, and the connection drops: To log on to this remote computer, you must have Terminal Server User Access persmissions on this computer. By default, members of the Remote Desktop Users group have these permissions. If you are not a member of the Remote Desktop Users group or another group that has these persmissions, or if the Remote Desktop User group does not have these permissions, you must be granted these permissions manually. The issue is that the user is a member of the Administrators group, which has permission. Also, logging in using the same username, but from an XP SP2 machine, has no problems at all. I hope I explained this well enough, and any help/insight that can be given would be greatly appreciated. Thanks, Tom

• can't Remote desktop to windows XP, blaming the server side

  - by Jin

  After rebooting my work PC (windows XP sp3) this Wednesday (thank to Microsoft Tuesday), I found that I can't remote desktop to my work PC from home (with VPN to company). I have been remote-desktop to work for years and I am really surprised since connectivity is not the problem, so I brought up wireshark to sniff the packets. I can see after TCP handshake, client sent X.224 Connection Request 03 00 00 13 0e e0 00 00 00 00 00 01 00 08 00 03 00 00 00 server sent X.224 Connection Confirm. 03 00 00 0b 06 d0 00 00 12 34 00 According to "MS-RDPBCGR", the official spec on RDP, the server should include Negotiation Response in the "Connection Confirm" message but it didn't. It's empty. I googled a lot but didn't find any clue on why server did that. By the way, I used the same remote desktop client and can connect to other windows XP PC. Here are a couple of pieces of information that may help to give a clue: Since TCP handshake (server port being 3389), I believe the svchost service is actually running. going to control panel -- system window, --- "Remote" tab, the remote desktop is indeeded checked and it states that my username is allowed. according to the packet capture, client didn't even get a chance to tell server what user was trying to logon. Yes, the progress bar showed up a few seconds and then it went back to the "Remote desktop Connection" window again. Searched "windowsupdate.log", didn't find any appearance of the word "remote".

• Samba and Windows 7

  - by John Gaughan

  I built a new computer with the intention of it being primarily a home file server. Here is my setup: one desktop with Windows 7 64 HP one laptop with Windows 7 64 HP one desktop with Kubuntu 11.10 (server) The two desktops use static IPs, and I have hostnames mapped in the HOSTS files on all three systems. I have the same username/password combo on all three systems. I have been trying for a while now to set up Samba so the Windows 7 systems can see and use it. Even if I can get the server to show up, Windows is unable to log in. One of the first things I did was to enable LMv2 authentication, which this version of Samba (3.5.11) supports. The workgroup is set correctly. I can normally see the server, but cannot authenticate. Windows homegroup is turned off. Pinging between machines works fine, and the two Windows 7 systems work together flawlessly. What I am trying to do is set up Samba to use peer to peer networking using NTLM security and user-mode authentication. According to the documentation this is possible, but there are no examples that I could find. In all the googling I have done, I see a lot of people asking how to set this up but it either works for someone else and not for me (no idea what I'm missing), or it doesn't work. Has anyone gotten this to work? Is there a place I could download a smb.conf that is set up to work in this environment?

• SQL Server 2005 standard filegroups / files for performance on SAN

  - by Blootac

  I submitted this to stack overflow (here) but realised it should really be on serverfault. so apologies for the incorrect and duplicate posting: Ok so I've just been on a SQL Server course and we discussed the usage scenarios of multiple filegroups and files when in use over local RAID and local disks but we didn't touch SAN scenarios so my question is as follows; I currently have a 250 gig database running on SQL Server 2005 where some tables have a huge number of writes and others are fairly static. The database and all objects reside in a single file group with a single data file. The log file is also on the same volume. My interpretation is that separate data files should be used across different disks to lessen disk contention and that file groups should be used for partitioning of data. However, with a SAN you obviously don't really have the same issue of disk contention that you do with a small RAID setup (or at least we don't at the moment), and standard edition doesn't support partitioning. So in order to improve parallelism what should I do? My understanding of various Microsoft publications is that if I increase the number of data files, separate threads can act across each file separately. Which leads me to the question how many files should I have. One per core? Should I be putting tables and indexes with high levels of activity in separate file groups, each with the same number of data files as we have cores? Thank you
