• Windows Server 2008 (Web Server) Replication

  - by justjoshingyou

  We have a load balanced environment with Windows Server 2008. What are some best practices to setting up replication across the web servers? Do I only want to replicate the web folders? How about replicating IIS changes - or do I need to make IIS changes on every server? I've never, ever set up replication, but I have worked with a web farm that used it before. Basically, I only know the basics about how it works, and am looking for any advice, guides, warnings, etc on setting this up. If you'd like to offer any advice, I'll let you know how our environment is for now. We have 1 prod server up and the second is nearly ready to go. We are using a cloud system and all machines are VM's. I am in the process of setting up the domain controller now (as I need to have one for DFS). Any ideas on the best way to go about setting up replication? Should we just stick the prod server in from the start or set up using a test VM and our second server and then switch it up later? I do not want to risk overwriting our prod server. Thanks!

• SQL Server 2008 Cluster Installation - First network name always fails

  - by boflynn

  I'm testing failover clustering in Windows Server 2008 to host a SQL Server 2008 installation using this installation guide. My base cluster is installed and working properly, as well as clustering the DTC service. However, when it comes time to install SQL Server, my first attempt at installation always fails with the same message and seems to "taint" the network name. For example, with my previous cluster attempt, I was installing SQL Server as VSQL. After approximately 15 attempts of installation and trying to resolve the errors, e.g. changing domain accounts for SQL, setting SPNs, etc., I typoed the network name as VQSL and the installation worked. Similarly on my current cluster, I tried installing with the SQL service named PROD-C1-DB and got the same errors as last time until I tried changing the name to anything else, e.g. PROD-C1-DB1, SQL, TEST, etc., at which point the install works. It will even install to VSQL now. While testing, my install routine was: Run setup.exe from patched media, selecting appropriate options After the install fails, I'd chose "Remove node from a SQL Server failover cluster" and remove the single, failed, node Attempt to diagnose problem, inspect event logs, etc. Delete the computer account that was created for the SQL Service from Active Directory Delete the MSSQL10.MSSQLSERVER folder from the shared data drive The error message I receive from the SQL Server installer is: The following error has occurred: The cluster resource 'SQL Server' could not be brought online. Error: The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F) Along with hundreds of the following errors in the Application event log: [sqsrvres] checkODBCConnectError: sqlstate = 28000; native error = 4818; message = [Microsoft][SQL Server Native Client 10.0][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

• Mac creating files w/ wrong perms on samba share

  - by geoffjentry

  In my group, which is very heterogeneous in terms of machines, we use a samba share to collaborate on files and such. In all but one case, it works as expected (or at least close enough). The one exception is my boss' laptop, a snow leopard macbook air. On his desktop (also snow leopard), if he creates a file it ends up serverside with perms of 774, but when he creates it with the Air, the perms are 644. The key problem is the lack of group write permission on the laptop created files. What's really confusing is that everything that I've looked at on the two machines are identical - same version of OS X, same version of samba (3.0.25b-apple), same settings for the same software, etc. I can't imagine why one machine would be different than the other, but it is. To try to be complete w/ the description, here is the relevant portion of my smb.conf file: comment = my Share path = /path/to/share public = no writeable = yes printable = no force group = myshare directory mask = 0770 create mask = 0770 force create mode = 0770 force directory mode = 0770 EDIT: I looked at three more Macs and all of them worked as expected which leaves this one laptop the true oddball. This wasn't as good as a test as the others though, as they were all leopard.

• Where to get glib-config for Kubuntu?

  - by Carl Smotricz

  I'm trying to compile Midnight Commander on a KUbuntu 9.10 (Karmic) box with no root access. I've set up a directory under $HOME, downloaded the mc source package and various stuff required for building, such as autotools. I've unpacked the CONTENTS of all those packages into this working directory such that I have the usual ./usr, ./lib, ./etc hierarchy. I manage to get configure through a lot of tests, but I can't seem to fool it into finding glib. checking for glib-2.0... checking for glib-config... no checking for glib12-config... no checking for glib-config... no checking for GLIB - version >= 1.2.6... no *** The glib-config script installed by GLIB could not be found *** If GLIB was installed in PREFIX, make sure PREFIX/bin is in *** your path, or set the GLIB_CONFIG environment variable to the *** full path to glib-config. configure: error: Test for glib failed. GNU Midnight Commander requires glib 1.2.6 or above. My system has glib installed: /lib/libglib-2.0.so.0 /lib/libglib-2.0.so.0.2200.3 ... and I've also downloaded and unpacked the glib package into my working directory: libglib2.0-0_2.22.2-0ubuntu1_i386.deb libglib2.0-dev_2.22.2-0ubuntu1_i386.deb ... but still the elusive glib-config is nowhere to be found. It's not in any debian package for Karmic, either. So I'd appreciate any help getting over this hurdle. Please note, again, that I don't have root, so I can't just merrily apt-get stuff.

• AVCHD MTS h264 1080p file with choppy playback in Linux

  - by marc

  When I'm trying play video files from my camera: Seems stream 0 codec frame rate differs from container frame rate: 50.00 (50/1) -> 50.00 (50/1) Input #0, mpegts, from '00027.MTS': Duration: 00:00:38.88, start: 2.884289, bitrate: 16945 kb/s Program 1 Stream #0.0[0x1011]: Video: h264 (High), yuv420p, 1920x1080 [PAR 1:1 DAR 16:9], 50 fps, 50 tbr, 90k tbn, 50 tbc Stream #0.1[0x1100]: Audio: ac3, 48000 Hz, stereo, s16, 256 kb/s … on my Linux computer (Ubuntu 12.04), I get choppy playback. It's completly unusable... I tried: Totem VLC mplayer The result is always same issue. I sent the same video file to a friend who has ubuntu 10.04 to test, and he also has the same issue. He has Windows 7, and confirms that on Windows, the video work well. I have an Intel® Core™2 CPU 6300 @ 1.86GHz × 2 with GF 9600 GT, with closed NVIDIA drivers. This is not any kind of issue with big files playing slow from an HDD issue. I have an SSD drive! I spent the last days and nights, trying hundreds of commands for ffmpeg, handbrake, mencoder... Any of them won't let me create a file with enough quality. I downloaded few movies from YouTube in 1080p, and playback worked well without any big pixels and choppiness. I would like have highest possible quality, I will put following files onto a Blu-ray disk so I don't need to compress them to get a smaller size. I just want smoth playback on my Linux box. On Windows, the same file is working well.

• Compressing and copying large files on Windows Server?

  - by Aaron

  I've been having a hard time copying large database backups from the database server to a test box at another site. I'm open to any ideas that would help me get this database moved without having to resort to a USB hard drive and the mail. The database server is running Windows Server 2003 R2 Enterprise, 16 GB of RAM and two quad-core 3.0 GHz Xeon X5450s. Files are SQL Server 2005 backup files between 100 GB and 250 GB. The pipe is not the fastest and SQL Server backup files typically compress down to 10-40% of the original, so it made sense to me to compress the files first. I've tried a number of methods, including: gzip 1.2.4 (UnxUtils) and 1.3.12 (GnuWin) bzip2 1.0.1 (UnxUtils) and 1.0.5 (Cygwin) WinRAR 3.90 7-Zip 4.65 (7za.exe) I've attempted to use WinRAR and 7-Zip options for splitting into multiple segments. 7za.exe has worked well for me for database backups on another server, which has ~50 GB backups. I've also tried splitting the .BAK file first with various utilities and compressing the resulting segments. No joy with that approach either- no matter the tool I've tried, it ends up butting against the size of the file. Especially frustrating is that I've transferred files of similar size on Unix boxes without problems using rsync+ssh. Installing an SSH server is not an option for the situation I'm in, unfortunately. For example, this is how 7-Zip dies: H:\dbatmp>7za.exe a -t7z -v250m -mx3 h:\dbatmp\zip\db-20100419_1228.7z h:\dbatmp\db-20100419_1228.bak 7-Zip (A) 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Scanning Creating archive h:\dbatmp\zip\db-20100419_1228.7z Compressing db-20100419_1228.bak System error: Unspecified error

• SQL Query to update parent record with child record values

  - by Wells

  I need to create a Trigger that fires when a child record (Codes) is added, updated or deleted. The Trigger stuffs a string of comma separated Code values from all child records (Codes) into a single field in the parent record (Projects) of the added, updated or deleted child record. I am stuck on writing a correct query to retrieve the Code values from just those child records that are the children of a single parent record. -- Create the test tables CREATE TABLE projects ( ProjectId varchar(16) PRIMARY KEY, ProjectName varchar(100), Codestring nvarchar(100) ) GO CREATE TABLE prcodes ( CodeId varchar(16) PRIMARY KEY, Code varchar (4), ProjectId varchar(16) ) GO -- Add sample data to tables: Two projects records, one with 3 child records, the other with 2. INSERT INTO projects (ProjectId, ProjectName) SELECT '101','Smith' UNION ALL SELECT '102','Jones' GO INSERT INTO prcodes (CodeId, Code, ProjectId) SELECT 'A1','Blue', '101' UNION ALL SELECT 'A2','Pink', '101' UNION ALL SELECT 'A3','Gray', '101' UNION ALL SELECT 'A4','Blue', '102' UNION ALL SELECT 'A5','Gray', '102' GO I am stuck on how to create a correct Update query. Can you help fix this query? -- Partially working, but stuffs all values, not just values from chile (prcodes) records of parent (projects) UPDATE proj SET proj.Codestring = (SELECT STUFF((SELECT ',' + prc.Code FROM projects proj INNER JOIN prcodes prc ON proj.ProjectId = prc.ProjectId ORDER BY 1 ASC FOR XML PATH('')),1, 1, '')) The result I get for the Codestring field in Projects is: ProjectId ProjectName Codestring 101 Smith Blue,Blue,Gray,Gray,Pink ... But the result I need for the Codestring field in Projects is: ProjectId ProjectName Codestring 101 Smith Blue,Pink,Gray ... Here is my start on the Trigger. The Update query, above, will be added to this Trigger. Can you help me complete the Trigger creation query?

• PHP Output buffer flush issue on Apache/Linux

  - by Iiro Vaahtojärvi

  Hi, I'm running into issues with the PHP output buffer flushing on my Linux web server. The output buffer is maintained correctly and all the right data is pushed to it in my code, but the usual flushing mechanisms won't flush it to the browser. I have tried everything posted here: http://php.net/manual/en/function.flush.php but no success so far. I got a small script from php.net to test it: <?php ob_start(); for($i=0;$i<70;$i++) { echo 'printing...<br />'; ob_get_flush(); flush(); usleep(300000); } ?> This should print "printing..." to the browser 70 times, one line every three seconds. This works fine on my other testing environment which is based on Windows (still using apache, XAMPP package), but on my Linux server it doesn't. It waits for the script to finish before giving anything to the browser, basically ignoring the whole flush command. If anyone has experienced this before or knows of anything that could help (be it server configuration or adjustment to code) it would be greatly appreciated!

• Do entries in local 'hosts' files override both forward and reverse name lookups?

  - by Murali Suriar

  If I have the following entries in a hosts file: 192.168.100.1 bugs 192.168.100.2 daffy.example.com 192.168.100.3 elmer.example.com. Will IP-name resolution attempts by local utilies (I assume using 'gethostbyaddr' or the Windows equivalent) honour these entries? Is this behaviour configurable? How does it vary between operating systems? Does it matter whether the 'hosts' file entries are fully qualified or not? EDIT: In response to Russell, my test Linux system is running RHEL 4. My /etc/nsswitch.conf contains the following 'hosts' line: hosts: files dns nis If I ping any of my hosts by name (e.g. bugs, daffy), the forward resolution works correctly. If I traceroute any of them by IP address, the reverse lookup functions as expected. However, if I ping them by IP, ping doesn't appear to resolve their host names. My understanding was that Linux ping would always attempt to resolve IPs to names unless instructed otherwise. Why would traceroute be able to handle reverse lookups in hosts files, but ping not?

• How can I recover a Fedora 12 installation that is showing signs of disk errors?

  - by Bob Cross

  I am currently overseas (i.e., very far from my normal library of tools) and my primary machine that would normally act as the data server in the performance test that we're trying to run is failing to boot to Fedora 12 properly. This is a machine that, as of yesterday, was booting fine. However, this morning, very strange portions of the boot process were complaining with messages such as "unexpected 0x0 in rpcbind" and "bad file descriptor" (I don't have the error in front of me - scavenged a windows installation to get onto serverfault). Eventually, the boot hung for a long time at the NFS service and then brought up what looked like the KDE login screen but neither the mouse nor keyboard functioned. In olden days, I would try to get to a point where I could manage to run fsck and pray that the bad sectors would come back into alignment just long enough for me to scrape the critical data off of the machine. However, now that we live in the future, it seems like our options in situations like this should be a little more varied. Is there a way to recover a Fedora 12 installation with bad disk sectors that won't boot properly? For completeness, I am comfortable working with bootable recovery distros-on-CD and such but I don't know which one is likely to work best with modern Fedora. In the absence of guidance, I'm frantically torrenting the Fedora 12 Live CD and DVD, hoping to try rescue mode before tomorrow morning.

• 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

• Accessing Virtual Host from outside LAN

  - by Ray

  I'm setting up a web development platform that makes things as easy as possible to write and test all code on my local machine, and sync this with my web server. I setup several virtual hosts so that I can access my projects by typing in "project" instead of "localhost/project" as the URL. I also want to set this up so that I can access my projects from any network. I signed up for a DYNDNS URL that points to my computer's IP address. This worked great from anywhere before I setup the virtual hosts. Now when I try to access my projects by typing in my DYNDNS URL, I get the 403 Forbidden Error message, "You don't have permission to access / on this server." To setup my virtual hosts, I edited two files - hosts in the system32/drivers/etc folder, and httpd-vhosts.conf in the Apache folder of my WAMP installation. In the hosts file, I simply added the server name to associate with 127.0.0.1. I added the following to the http-vhosts.conf file: <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot "c:/wamp/www/ladybug" ServerName ladybug ErrorLog "logs/your_own-error.log" CustomLog "logs/your_own-access.log" common </VirtualHost> <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot "c:/wamp/www" ServerName localhost ErrorLog "logs/localhost-error.log" CustomLog "logs/localhost-access.log" common </VirtualHost> Any idea why I can't access my projects from typing in my DYNDNS URL? Also, is it possible to setup virtual hosts so that when I type in http://projects from a random computer outside of my network, I access url.dyndns.info/projects (a.k.a. my WAMP projects on my home computer)? Help is much appreciated, thanks!

• How can I override mod-php5's .php mapping to php4-cgi per VirtualHost or Directory?

  - by geocoo

  I am running Debian Linux with apache2 and libapache2-mod-php5 5.3.3-7. I have one VirtualHost which requires php4. So I researched and compiled php4-cgi. However, I cannot seem to: Override mod-php5's mapping of .php in that vhost (or even globally, without disabling php completley). Even find where that mapping is made, in hope of disabling it and enabling mod-php5 or php4-cgi per vhost. This is my php4-cgi mapping (Inside the one php4 vhost): ScriptAlias /php4 /usr/local/php4/bin <Directory /usr/local/php4/bin> Options +ExecCGI +FollowSymLinks </Directory> <Directory /www/test> AddHandler php4-cgi-script .php Action php4-cgi-script /php4/php Options +ExecCGI </Directory> This does not work, mod-php5 still runs all .php files in that vhost/directory. If I change the file extension in the AddHandler above from .php to .php4, then .php4 files do run php4-cgi as expected, but I can't change all the files in the app to .php4. I thought maybe I could disable the mod-php5's mapping in my vhost or directory, then do my cgi-config (as above) but many combinations of these in different contexts did not work: RemoveHandler .php RemoveType .php php_flag engine off (this seems to even disable my php4-cgi so that wont work) The only other place I can find any mapping is in /etc/mime.types, but commenting out the relevant lines and restarting apache2 does not affect mod-php5's .php mapping. I have searched as much as I can, it is now a mystery to me. Any help or direction would be greatly appreciated.

• Performance: Nginx SSL slowness or just SSL slowness in general?

  - by Mauvis Ledford

  I have an Amazon Web Services setup with an Apache instance behind Nginx with Nginx handling SSL and serving everything but the .php pages. In my ApacheBench tests I'm seeing this for my most expensive API call (which cache via Memcached): 100 concurrent calls to API call (http): 115ms (median) 260ms (max) 100 concurrent calls to API call (https): 6.1s (median) 11.9s (max) I've done a bit of research, disabled the most expensive SSL ciphers and enabled SSL caching (I know it doesn't help in this particular test.) Can you tell me why my SSL is taking so long? I've set up a massive EC2 server with 8CPUs and even applying consistent load to it only brings it up to 50% total CPU. I have 8 Nginx workers set and a bunch of Apache. Currently this whole setup is on one EC2 box but I plan to split it up and load balance it. There have been a few questions on this topic but none of those answers (disable expensive ciphers, cache ssl, seem to do anything.)

• CloudFlare dashboards empty, or performance issues

  - by Katafalkas

  I wanted to test CloudFlare performance so I set my image gallery domain on it and started testing. I have added PageRules for caching. And chose the Security: Essentially Off. I checked NS check tools and they say that my domain name is propagated with CloudFlare. For testing purpose I created a link that loads 200 images from that server, and was using loads.in website to determine how much it is faster. After trying few regions, I noticed that there were no improvement in loading speed. So I looked up the dashboards, and it was empty. I am not sure if I am doing something wrong, or made some error in my setup, or it takes few days to start caching or working properly, but at the moment - after a day of testing - dashboards are empty. Also the NS check tools sais that all name servers are propagated to CloudFlare and working fine. So I assume I got a bad performance because it is simply not working. I sent a letter to CloudFlare support team, but did not get any straight answer. So essentially my question is: Anyone has any experience with CloudFlare ? How long does it take for it to start caching static content to CDN ? Or there is simply something I am doing wrong ?

• "Error: Unknown error" when trying to start virtual machine from VMware server

  - by slhck

  Problem We are running VMware Server 2.0.0 build-116503 on a Ubuntu 10.04 LTS server. There is a virtual machine installed, running Lotus Domino on Windows Server 2003. Ever since a sudden power failure last week, the virtual machine won't properly start up. When I run the command: vmrun -T server -h https://127.0.0.1:8333/sdk -u root -p jk2x2208 start "[standard] lotus/test.vmx" … after 30 seconds it displays: Error: Unknown error That's about everything I get. I know the command is right, since that's what we've used all the time. This has happened last Saturday after a scheduled backup shutdown, and somehow I was able to start it again. This week, it happened again, and I can't get it back up. Occasionally, I also get: Error: Cannot connect to the virtual machine When I get this, and I run the start command, it seemingly works. Why is this so random? Which configuration could have been messed up? What I've tried / other info I already shut down VMware itself with /etc/init.d/vmware stop. This works. I tried to start VMware again with /etc/init.d/vmware start. It complains that it's "not configured", which is why I had to rm /etc/vmware/not_configured, and then try to start again. There have been no software updates on the machine, and no configuration changes

• AD domain on web servers behind NAT - DNS issues?

  - by Ant

  I'm trying to setup an AD domain to manage the security between two Windows Server 2008 webservers that will sooner or later use NLB to balance website requests. I've hit a problem which I think is a simple solution and is down to DNS. My website domain is mydomain.com. The two servers are running behind a NAT firewall on the 10.0.0.0 IP range. I've setup the AD domain to be called ad.mydomain.com (as recommended by MS and a few other answers to questions on here). The second web server however doesn't want to join the domain, and gives an error pinning the problem on DNS - "ensure that the domain name is typed correctly" even though it queries the SRV record successfully and gets the correct DC back - dc.ad.mydomain.com. Doing a dcdiag /test:dns on the DC gives the Delegation error 'DNS Server dc.mydomain.com Missing glue A record'. I have a feeling I need to add something to the public DNS so that it in some way knows about ad.mydomain.com. Can anyone suggest whether I'm on the right track in adding something to the public DNS? Or whether it's something else? Many thanks

• vmware vmdk disk problem

  - by dmtr

  Hello, I have a vmware esxi 4 server and 2 storage servers (mount as nfs). Between the storage servers (fedora 14) is made drbd cluster (dual primary) and ocfs2 filesystem, also every server has local partition with ext4 filesystem, both are mounted as nfs on esxi server. When i tried to copy a virtual machine (naturally it power off) files from ext4 partition to ocfs2 partition, vmdk total file size is different, but md5sum is the same. on ext4 partition: # ls -la total 28492228 -rw------- 1 root root 42949672960 Jan 14 14:46 disk-flat.vmdk # md5sum disk-flat.vmdk 0eaebe3138beb32f54ea5de6dfe5a987 on ocfs2 partition: # ls -la total 13974660 -rw------- 1 root root 42949672960 Jan 14 16:16 disk-flat.vmdk # md5sum disk-flat.vmdk 0eaebe3138beb32f54ea5de6dfe5a987 When i power on the virtual machine from ocfs2 partition it dosn't work. I have a windows on the virtual machine and it freez?s after windows logo. From ext4 partition the virtual machine is worked. Test with linux (create and install on ext4 partition and copy) the same problem appears. When i create a virtual machine directly from ocfs2 partition, there are no problems. I tried to copy via vSphere client, and i have the same problem. Any suggestions ?

• Rebuild Fedora 19 ISO adding Kickstart for USB install

  - by dooffas

  I am attempting to edit a Fedora 19 DVD ISO to add a kickstart file. I then need this ISO burnt to a USB stick for instillation. The error I get when booting is Warning: Could not boot. Warning: /dev/root does not exist To try and determine which part of the process is failing I have broken the process down in to separate stages. Step 1: Burn the original ISO "Fedora-19-x86_64-DVD.iso" (Available - here) to a pendrive and see if that will install. dd if=/path/to/iso of=/dev/sdc Burning this image was successful and it installed without issue. Step 2: Exctract the ISO, repackage it and burn it to a pendrive and see if that will install. PLEASE NOTE: The final command in this section has been broken down in to multiple lines for ease of reading, in fact it was run as a single command on one line. mkdir -p /mnt/linux mount -o loop /tmp/linux-install.iso /mnt/linux cd /mnt/ tar -cvf - linux | (cd /var/tmp/ && tar -xf - ) cd /var/tmp/linux xorriso -as mkisofs -R -J -V "NewFedoraImage" -o ouput/file.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -isohybrid-mbr /usr/share/syslinux/isohdpfx.bin . This iso was then burnt to a pendrive as before. dd if=/path/to/iso of=/dev/sdc This ISO burnt to the pen drive with no problem and will boot. I then see the fedora options screen. After choosing either "Install Fedora 19" or "Test this media & install Fedora 19" I then receive the errors highlighted above. This means the kickstart file is not to blame, but repackaging the ISO. Is there something I am missing in the repackaging process? Any input would be great! NOTE: If it is of any help, I attempted Step 2 with an Ubuntu server ISO and the process was successful.

• Creating Active Directory on an EC2 box

  - by Chiggins

  So I have Active Directory set up on a Windows Server 2008 Amazon EC2 server. Its set up correctly I think, I never got any errors with it. Just to test that I got it all set up correctly, I have a Windows 7 Professional virtual machine set up on my network to join to AD. I set the VM to use the Active Directory box as its DNS server. I type in my domain to join it, but I get the following error: DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain "ad.win.chigs.me": The query was for the SRV record for _ldap._tcp.dc._msdcs.ad.win.chigs.me The following domain controllers were identified by the query: ip-0af92ac4.ad.win.chigs.me However no domain controllers could be contacted. Common causes of this error include: - Host (A) or (AAAA) records that map the names of the domain controllers to their IP addresses are missing or contain incorrect addresses. - Domain controllers registered in DNS are not connected to the network or are not running. It seems that I can talk to Active Directory, but when I'm trying to contact the Domain Controller, its giving a private IP to connect to, at least thats what I can make out of it. Here are some nslookup results. > win.chigs.me Server: ec2-184-73-35-150.compute-1.amazonaws.com Address: 184.73.35.150 Non-authoritative answer: Name: ec2-184-73-35-150.compute-1.amazonaws.com Address: 10.249.42.196 Aliases: win.chigs.me > ad.win.chigs.me Server: ec2-184-73-35-150.compute-1.amazonaws.com Address: 184.73.35.150 Name: ad.win.chigs.me Address: 10.249.42.196 win.chigs.me and ad.win.chigs.me are CNAME's pointing to my EC2 box. Any idea what I need to do so that I can join my virtual machine to the EC2 Active Directory set up I have? Thanks!

• Backing up Excel Files to a different Directory

  - by Joe Taylor

  In Excel 2007 in the Save As box there is an option to 'Create a Backup' which simply backs up the file whenever it is saved. Unfortunately it backs up the file to the same directory as the original. Is there a simple way to change this directory to another drive / folder? I have messed about with macros to do this, coming up with: Private Sub Workbook_BeforeClose(Cancel As Boolean) 'Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean) 'Saves the current file to a backup folder and the default folder 'Note that any backup is overwritten Application.DisplayAlerts = False ActiveWorkbook.SaveCopyAs Filename:="T:\TEC_SERV\Backup file folder - DO NOT DELETE\" & _ ActiveWorkbook.Name ActiveWorkbook.Save Application.DisplayAlerts = True End Sub This creates a backup of the file ok the first time, however if this is tried again I get: Run-Time Error '1004'; Microsoft Office Excel cannot access the file 'T:\TEC_SERV\Backup file folder - DO NOT DELETE\Test Macro Sheet.xlsm. There are several possible reasons: The file name or path does not exist The file is being used by another program The workbook you are trying to save has the same name as a... I know the path is correct, I also know that the file is not open anywhere else. The workbook has the same name as the one I'm trying to save over but it should just overwrite. I have posted the question about the coding on Stack Overflow but wondered if there is an easier way to do this. Any help would be much appreciated. Joe

• Clipboard bug in Wordpad in Windows 7 (accidentally pasting large file into application)

  - by frenchglen

  In Win7, I use Wordpad, and I really like it. For my needs it's lean and fast, yet has the formatting functionalities I'm after when working on my TXT/RTF files on a daily basis. I don't intend to change text editors. There's a really bad bug which has ALWAYS plagued me. If you have a large file contained in the clipboard, like a 238MB FLAC file, and you accidentally paste it into Wordpad for whatever reason - it hangs the application for a VERY long time (like 2 hours, it depends on how big the file is, because it tries to 'handle' it). You either have to close the application and lose any unsaved changes, or go do something else until the item has finished pasting into Wordpad (it actually eventually drops the file's icon in wordpad just like how it appears in Windows Explorer). It's a Windows bug, a Wordpad bug. Is there some solution for this? Or is the problem fixed in Windows 8 (if anyone can tell me)? .....I'm not going to try out Win8 myself, merely to answer this question - that's what I'm asking it on SuperUSer for! I'm really hoping it's one of those little-yet-big things that they've fixed in Win8 (like removing the 255-character file path limit in Explorer, which is awesome). Thank you for your help, if you have Win8 handy and can test this. :)

• Allow incoming connections on Windows Server 2008 R2

  - by Richard-MX

  Good day people. First, im new to Windows Server. I've always used Linux/Apache combo, but, my client has and AWS EC2 Windows Server 2008 R2 instance and he wants everything in there. Im working with IIS and PHP enabled as Fast-CGI and everything is working, but, i cant see the websites stored in it from internet. The public DNS that AWS gave us for that instance is: http://ec2-XX-XXX-XXX-121.us-west-2.compute.amazonaws.com/ But, if i copy paste that address, i get nothing, no IIS logo or something like that. My common sense tells me that maybe the firewall could be blocking the access. Can anyone help me and tell where to enable some rules to get this thing working? I don't wanna start enabling rules at random and make the system insecure. If you need any additional info, you can ask me and i will provide it. Thanks in advance. UPDATE: Amazon EC2 display this: Public DNS: ec2-XX-XXX-XXX-121.us-west-2.compute.amazonaws.com Private DNS: ip-XX-XXX-XX-252.us-west-2.compute.internal Private IPs: XX.XXX.XX.25 In my test microinstance, i just to use the Public DNS address (the one that starts with "ec2") and it works like a charm (of course, the micro instance have its own Public DNS im not assuming same address for both instances...) However, for the large instance, i tried to do the same. Set up everything as in the micro instance but if i use the Public DNS, it doesnt load anything. Im suspicious about the Windows Firewall, but, the HTTP related stuff is enabled. What should i do to get access to the large instance? I don't want to set up the domain yet, i want access from an amazon url. 2ND EDIT: all fixed. Charles pointed that maybe Security Groups was not properly set up for the instance. He was right. Just added HTTP service to the rules and all works good.
