• Why java -version returning a different version than the one defined in JAVA_HOME?

  - by Shekhar

  I am trying to set JAVA_HOME in Ubuntu OS. I have copied jdk 1.7 in /usr/lib/jvm and set JAVA_HOME in /etc/profile file. Contents of /usr/lib/jvm folder are as follows : shekhar@ubuntu:~$ ls /usr/lib/jvm/ default-java java-1.6.0-openjdk java-6-openjdk java-6-openjdk-i386 jdk1.7.0_01 java-1.5.0-gcj-4.6 java-1.6.0-openjdk-i386 java-6-openjdk-common java-7-openjdk-i386 and last few lines of /etc/profile file are as follows : export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_01 export PATH=$PATH:$JAVA_HOME/bin After finishing all this when I run java -version command I get following output : shekhar@ubuntu:~$ java -version java version "1.6.0_24" OpenJDK Runtime Environment (IcedTea6 1.11.4) (6b24-1.11.4-1ubuntu0.12.04.1) OpenJDK Server VM (build 20.0-b12, mixed mode) and when I run ls -lah command I get following output : shekhar@ubuntu:~$ ls -lah /usr/bin/java lrwxrwxrwx 1 root root 22 Sep 29 09:58 /usr/bin/java -> /etc/alternatives/java shekhar@ubuntu:~$ ls -lah /etc/alternatives/java lrwxrwxrwx 1 root root 45 Sep 29 09:58 /etc/alternatives/java -> /usr/lib/jvm/java-6-openjdk-i386/jre/bin/java Can anyone please tell me which thing I am missing? Why Ubuntu is still pointing to open jdk and not to my jdk 7? PS : I have seen this similar question and its answers but that question is related to Windows OS and not for Ubuntu so I am reposting this similar question for Ubuntu.

• Getting rid of your server in a small business environment

  - by andygeers

  In a small business environment, is it still necessary to have a central server? Speaking for my own company (a small charity with about 12 employees) we use our server (Windows Server 2003) for the following: Email via Microsoft Exchange Central storage Acting as a print server User authentication / Active Directory There are significant costs associated with running a server like this: Electricity, first for the server itself then for the air conditioning required (this thing pumps out a lot of heat) Noise (of which there is a lot) IT support bills (both Windows Server and Exchange are pretty complicated, and there are many ways they can go wrong) I've found ways to replace many of these functions with cheaper (better?) alternatives: Google Apps / GMail is a clear win for us: we have so many spam related problems it's not even funny, and Outlook is dog slow on our aging computers You can buy networked storage devices with built in print servers, such as the Netgear ReadyNAS™ RND4210 that would allow us to store/share all of our documents, and allow us to access printers over the network The only thing that I can't figure out how to do away with is the authentication side of things - it seems to me that if we got rid of our server, you'd essentially have a bunch of independent PCs that had no shared pool of user accounts / no central administrator. Is that right? Does that matter? Am I missing any other good reasons to keep a central server? Does anybody know of any good, cost-effective ways of achieving the same end but without the expensive central server?

• Five stars of open data - example and review

  - by Joe

  (there may be a more suited SE site for this question so feel free to shift) I have some data I'd like to make open to the public - It's synatesis of some related data retrived from freedom of infomation requests over the last year. The data itself is at http://www.cs.rhul.ac.uk/home/joseph/domesday/Domesday-Scotland.csv or for fans of Excel, at http://www.cs.rhul.ac.uk/home/joseph/domesday/Domesday-Scotland.xlsx . It's no more than a table with about five columns. I'd like to make this properly open data, so I was looking at the 5 star deployment scheme for Open Data. Much of which is fine but I'm confused towards the end and I could do with an explenation from people who know the answers. So to get achieve the star levels I need: "make your stuff available on the Web (whatever format) under an open license" trival - all I have to do is put the notes up on the page that will give the provance of the data. "make it available as structured data (e.g., Excel instead of image scan of a table)"… done… "use non-proprietary formats (e.g., CSV instead of Excel)" - done… "use URIs to identify things, so that people can point at your stuff" - this is where I start to get a bit hazy - does this mean there should be an URI for every line in the table? "link your data to other data to provide context" - this isn't massively clear to me - does this mean to give the provence of the data? One column of the data I've put out is a link to where the data came from - is that the sort of thing we're looking at? Any and all information and answers welcome… EDIT - or if anyone wants to recommend a place SE or other place to ask the question - that would be cool...

• What kinds of protections against viruses does Linux provide out of the box for the average user?

  - by ChocoDeveloper

  I know others have asked this, but I have other questions related to this. In particular, I'm concerned about the damage that the virus can do the user itself (his files), not the OS in general nor other users of the same machine. This question came to my mind because of that ransomware virus that is encrypting machines all over the world, and then asking the user to send a payment in Bitcoin if he wants to recover his files. I have already received and opened the email that is supposed to contain the virus, so I guess I didn't do that bad because nothing happened. But would I have survived if I opened the attachment and it was aimed at Linux users? I guess not. One of the advantages is that files are not executable by default right after downloading them. Is that just a bad default in Windows and could be fixed with a proper configuration? As a Linux user, I thought my machine was pretty secure by default, and I was even told that I shouldn't bother installing an antivirus. But I have read some people saying that the most important (or only?) difference is that Linux is just less popular, so almost no one writes viruses for it. Is that right? What else can I do to be safe from this kind of ransomware virus? Not automatically executing random files from unknown sources seems to be more than enough, but is it? I can't think of many other things a user can do to protect his own files (not the OS, not other users), because he has full permissions on them.

• hp DL380 G4 won't boot with disk plugged into front USB

  - by Kev

  We outgrew a few older external USB backup drives, and purchased WD My Passport 1 TB USB 3.0 drives to replace them. When they are plugged into the front of our G4, it will blink forever after the BIOS (which is current, BTW) and never boot, even though the USB disks are not "bootable" per se. Our old drives did not exhibit this behaviour (so I don't think it's this type of issue that I've read about other servers.) The old drives were USB 2.0, but this shouldn't make a difference, AFAICT--the specs say all of the G4's USB ports are the same, 2.0, anyway, so I'm not sure how one port would handle a USB 3.0 device better than another. If we plug the new drives in one of the back slots, it boots fine. What's the cause? My concern is that the front USB port, and possibly the motherboard, might be starting to die. (We are experiencing other strange issues with them, or were initially, like intermittent file permissions errors despite wide-open ACL on these local drives, but some serverfault users have me convinced they may be coincidental software/security related issues.)

• Intermittent Trouble Entering Hibernate on WinXP

  - by kquinn

  My personal desktop, running 32-bit Windows XP SP2 (with 4GB RAM, 2.75GB addressable, swap disabled, hiberfil.sys existing and contiguous on C:\; SP3 is not installed because SP2 has been working fine and I do not want to re-qualify with SP3 just for sheer perversity) typically gets hibernated at night. For a long time this worked great, but recently the machine has had trouble entering hibernation. Sometimes when I press my power button (configured to hibernate), the box will start the procedure for hibernating (i.e., go to the blue "Windows XP" background logo and display a message about entering hibernation), but before displaying the usual blue-on-black hibernation progress bar it will drop back to the desktop. No error messages appear, on screen or in the system log. The only record of unsuccessful hibernation attempts in the system log, which proudly proclaims that "The Windows Image Acquisition (WIA) service entered the running state." once per failed hibernation attempt. The problem is almost certainly resource related: if I then close one or more applications which are running, and repeat the exact same process, the machine will hibernate perfectly. There does not appear to be a reliable high-water mark for virtual or physical memory use, below which the machine is guaranteed to hibernate; it's different every time (though typically, below about 1.1–1.4 GB memory usage seems to be where hibernate succeeds most often). Memory may not even be the relevant resource; as far as I know, it could also be handles or sockets. This behavior is relatively recent: it has only started in the last few months; before then, I could hibernate reliably no matter what the current resource use of the system. This machine claims to have hotfix Q909095 installed, but since the symptoms of my problem match KB909095 rather well, I'm suspicious if this fix is actually working as intended. Any ideas on how to fix this or where to start debugging?

  Hello all! I´m a windows xp user (but not for much time...) and I usually see how my computer stop of responding me. The process is this: Firsly it became totally stopped or very slow for certain periods of 5 minutes. How could I do? After that it gets stopped (Even not totally because If I click on the bar I see a blinking response in the bar botton of the program I click on. It´s could be anything related with security (like the firewall or some virus)? Computer university: I usually experience this, using Matlab (R2007a) with System Generator (its respective compatible version) My personal laptop: It´s usually works well but when stopped periods became to appears I know in not much time it will became totally stopped. I usually see how Word 2007 get stopped and after a while my windows xp gets stopped. (well I can access to the the manage task pressing ctr+alt and...). The only solution I see is to kill program by program... My petition: Please, I need good references that help me how to think in order to avoid or to manage the problems previously described.

• How do I restore a Windows Server 2008 R2 bare metal backup to a Windows Server 2012 R2 Hyper-V instance?

  - by Michael J. Gray

  I have been trying to find a simple way to migrate a physical Windows Server 2008 R2 installation over to a virtual machine hosted on Windows Server 2012 R2 Datacenter Edition /w Hyper-V. I came across the bare metal backup feature on Windows Server 2008 R2 and assumed I would be able to easily back it up and simply restore it into a new virtual machine by booting the installation media and getting into the Windows recovery process. When I attempted this, Hyper-V got into a network based restore process, but I do not have a PXE server or anything like that and I would rather not set it up. I tried mounting the VHD produced in the bare metal backup, just to see if it would somehow work, but it of course did not and failed with an error related to an incorrect boot device. I checked the virtual machine's BIOS settings and everything looked fine. I did not expect this to work anyway, so I stopped working through this method any further. Is there a way to take my bare metal backup and restore it into a virtual machine without a PXE server or SCVMM? I am opening to using proprietary tools but since the last time I did this I used Norton Ghost, which is no longer supported, I figured I would try doing it with what is readily available.

• What's needed in a complete ASP.NET environment?

  - by Christian W

  We have a ASP3.0 application with a few ASP.NET (2.0) dittys mixed in. (Our longtime goal is to migrate everything to ASP.NET but that's not important for this issue) Our current test/deploy workflow is like this: 1 Use notepad++ or VS2008 to fix a bug/feature (depending on what I have open) 2 Open my virtual test-server 3 Copy the fixed file over, either with explorer, or if I can be bothered to open it, WinMerge 4 Test that the fix works 5 Close the virtual test-server 6 Connect to our host with VPN 7 Use WinMerge to update the files necessary 8 Pray to higher powers that the production environment is not so different that something bombs. To make things worse, only I have access to my "test-server". So I'm the only one testing it. I really want to make this a bit more robust, I even have a subversion setup running. But I always forget to commit changes... And I don't even work in my checked out folder, but a copy of what is currently in production... Can someone recommend some good reading on deploying, testing, staging and stuff like that. I currently use VS2008 and want to use subversion or GIT (or any other free VCS). Since I'm the only developer, teamsystem is not really an option (cost-related). I have found myself developing an "improved" feature, only to find a bug in the same feature in the production system. And since my "improved" feature incorporated deleting some old functionality, I have to fix bugs directly in production... That's not a fun feeling... (I have inherited this system recently... So it's not directly my fault that it is like this ;) )

• How to use Cisco AnyConnect VPN Client?

  - by ktm5124

  I wrote a related question earlier, which is still unresolved. This question is much more specific. So I installed Cisco AnyConnect VPN Client on Snow Leopard. I connect to my work VPN. Once connected, I can't ping my work machine. I don't see any computers on the network. If the client were not running, I wouldn't believe myself to be connected to the VPN. Is there something that I am doing wrong? Do I have to route my network traffic through the tunnel manually? (ifconfig route comes to mind) Is the POST request that I am about to submit going to go through the tunnel created by my VPN? I guess the main question is: why do I feel so in the dark? Cisco says I am connected to my VPN, but for all I know it is invisible. N.B. I do have the up-to-date Cisco VPN Client: version 2.3.2016. I installed it about a week ago.

• CSS and JS files not being updated, supposedly because of Nginx Caching

  - by Alberto Elias

  I have my web app working with AppCache and I would like that when I modify my html/css/js files, and then update my Cache Manifest, that when the user accesses my web app, they will have an updated version of those files. If I change an HTML file, it works perfectly, but when I change CSS and JS files, the old version is still being used. I've been checking everything out and I think it's related to my nginx configuration. I have a cache.conf file that contains the following: gzip on; gzip_types text/css application/x-javascript text/x-component text/richtext image/svg+xml text/plain text/xsd text/xsl text/xml image/x-icon; location ~ \.(css|js|htc)$ { expires 31536000s; add_header Pragma "public"; add_header Cache-Control "max-age=31536000, public, must-revalidate, proxy-revalidate"; } location ~ \.(html|htm|rtf|rtx|svg|svgz|txt|xsd|xsl|xml)$ { expires 3600s; add_header Pragma "public"; add_header Cache-Control "max-age=3600, public, must-revalidate, proxy-revalidate"; } And in default.conf I have my locations. I would like to have this caching working on all locations except one, how could I configure this? I've tried the following and it isn't working: location /dir1/dir2/ { root /var/www/dir1; add_header Pragma "no-cache"; add_header Cache-Control "private"; expires off; } Thanks

• Which events specifically cause Windows 2008 to mark a SAN volume offline?

  - by Jeremy

  I am searching for specific criteria/events that will cause Windows 2008 to mark a SAN volume as offline in disk management, even though it is connected to that SAN volume via FC or iSCSI. Microsoft states that "A dynamic disk may become Offline if it is corrupted or intermittently unavailable. A dynamic disk may also become Offline if you attempt to import a foreign (dynamic) disk and the import fails. An error icon appears on the Offline disk. Only dynamic disks display the Missing or Offline status." I am specifically wondering if, on the SAN, changing the path to the disk (such as the disk being presented to the host via a different iSCSI target IQN or a different LUN #) would cause a volume to be offlined in disk management. Thanks! Edit: I have already found two reasons why a disk might be set offline, disk signature collisions and the SAN disk policy. Bounty would be awarded to someone who can find further documented reasons related to changes in the volume's path. Disk signature collisions: http://blogs.technet.com/b/markrussinovich/archive/2011/11/08/3463572.aspx SAN disk policy: http://jeffwouters.nl/index.php/2011/06/disk-offline-with-error-the-disk-is-offline-because-of-a-policy-set-by-an-administrator/

• Windows Network File Transfer to Samba server: “Are you sure you want to copy this file without its properties?”

  - by jimp

  I am transferring a lot of files to a new NAS based on OpenMediaVault, with the Samba 3.5.6 service running. I am transferring from Windows 7 64-bit to the NAS, and on some media files Windows is prompting about losing some property data across the transfer. I have never seen this before when transferring to Samba boxes I have built myself (vs this turnkey solution), so I'm guessing there must be a Samba setting I can change to preserve the file properties in question instead of permanently losing whatever they contain (Date Taken? Exposure? Flash Fired? etc). Or maybe I've just never encountered this before; I'm really not sure. I tried adding ea support = yes and store dos attributes = yes to the [global] section, but the problem remains. The Linux file system is ext4 mounted with user_xattr (full options: defaults,acl,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0) as Samba requires. Any ideas would be greatly appreciated. Thank you! Samba config: [global] workgroup = WORKGROUP server string = %h server include = /etc/samba/dhcp.conf dns proxy = no log level = 2 syslog = 2 log file = /var/log/samba/log.%m max log size = 1000 syslog only = yes panic action = /usr/share/samba/panic-action %d encrypt passwords = true passdb backend = tdbsam obey pam restrictions = yes unix password sync = no passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* . pam password change = yes socket options = TCP_NODELAY IPTOS_LOWDELAY guest account = nobody load printers = no disable spoolss = yes printing = bsd printcap name = /dev/null unix extensions = yes wide links = no create mask = 0777 directory mask = 0777 use sendfile = no null passwords = no local master = yes time server = yes wins support = yes ea support = yes store dos attributes = yes Note: I found this related question, but it explains the loss due to the user trying to transfer from NTFS to FAT32.

• Move the uploads folder in Wordpress

  - by Victor Hurdugaci

  Currently, my Wordpress' upload folder is located in \wp-content\uploads. Initially there was no structure so all files were put there. After a while it was changed to upload the files in \wp-content\uploads\YEAR\MONTH. Now that folder contains a mix of files (those starting with + are folders) like: +wp-content | +2010 | | +02 | | | File-1 | | | File-2 | | | .. | | | File-n | | +01 | | | File-1 | | | File-2 | | | .. | | | File-n | +2009 | | +12 | | | File-1 | | | File-2 | | | .. | | | File-n | | +11 | | | File-1 | | | File-2 | | | .. | | | File-n | +.. | | | .. | Unstructured-file-1 | Unstructured-file-2 | ... | Unstructured-file-n Based on the dates of the unstructured files, I would like to move them in a structured hierarchy (based on date, move it to a folder \wp-content\uploads\YEAR\MONTH). Now, my questions are: Where do I write and execute a script to the movement (I don't have full access to the server, just to a cPanel and to the Wordpress Admin page)? What must be updated so that the links in posts, that reference the unstructured files, point to the new location of those files? Not fully related to the previous description: is it alright to move the whole uploads folder to another location, like \uploads? PS: Moving the files/updating the database manually is not an option :)

• Destination NAT Onto the Same Network from internal clients

  - by mivi

  I have a DSL router which acts as NAT (SNAT & DNAT). I have setup a server on internal network (10.0.0.2 at port 43201). DSL router was configured to "port forward" (or DNAT) all incoming connections to 10.0.0.2:43201. I created a virtual server for port forwarding on DSL router. I also added following iptables rules for port forwarding. iptables -t nat -A PREROUTING -p tcp -i ppp_0_1_32_1 --dport 43201 -j DNAT --to-destination 10.0.0.2:43201 iptables -I FORWARD 1 -p tcp -m state --state NEW,ESTABLISHED,RELATED -d 10.0.0.2 --dport 43201 -j ACCEPT # ppp_0_1_32_1 is routers external interface. # routers internal IP address is 10.0.0.1 and server is setup at 10.0.0.2:43201 Problem is that connections coming from external IP addresses are able to access internal server using External IP address, but internal clients (under NAT) are not able to access server using external IP address. Example: http://<external_address>:43201 is working from external clients But, internal clients are not able to access using http://<external_address>:43201 This seems to be similar to the problem described in http://www.netfilter.org/documentation/HOWTO/NAT-HOWTO-10.html (NAT HOW-TO Destination NAT Onto the Same Network). Firstly, I am not able to understand why is this a problem for internal clients? Secondly, what iptables rule will enable internal clients to access server using external IP address? Please suggest.

• UDP blocked by Windows XP Firewall when sending to local machine

  - by user36367

  I work for a software development company but the issue doesn't seem to be programming-related. Here is my setup: Windows XP Professional with Service Pack 3, all updated Program that sends UDP datagrams Program that receives UDP datagrams Windows Firewall set to allow inbound UDP datagrams on a specific port (Scope: Subnet) If I send a UDP datagram on any port to other, similar machines, it goes through. If I send the UDP datagram to the same computer running the program that sends (whether using broadcast, localhost IP or the specific IP of the machine), the receiver program gets nothing. I've traced the problem down to the Windows XP Firewall, as Windows 7 does not have this problem (and I do not wish to sully my hands with Vista). If the exception I create for that UDP port in the WinXP firewall is set for a Scope of Subnet the datagram is blocked, but if I set it to All Computers or specifically enter my network settings (192.168.2.161 or 192.168.2.0/255.255.255.0) it works fine. Using different UDP ports makes no difference. I've tried different programs to reproduce this problem (ServerTalk to send and either IP Port Spy or PortPeeker to receive) to make sure it's not our code that's the issue, and those programs' datagrams were blocked as well. Also, that computer only has one network interface, so there are no additional network weirdness. I receive my IP from a DHCP server, so this is a straightforward setup. Given that it doesn't happen in Windows 7 I must assume it's a defect in the Windows XP Firewall, but I'd think someone else would have encountered this problem before. Has anyone encountered anything like this? Any ideas?

• WSUS KB978338 Chain of Supersession Incorrect?

  - by Kasius

  The chain appears to be KB978338 to KB978886 to KB2563894 to KB2588516 (newest). All four of these updates are approved on our WSUS server. KB978338 is listing as Not Applicable on all machines, because it has been superseded. This is the behavior I would expect. However, our security office is reporting that KB978338 should still be installed on all machines because its actual effect is not replicated by any of the updates that follow it. Here is the analysis I was sent: KB978886 applies to Vista SP1 only. The rollout of SP2 did not address the ISATAP vulnerability and reintroduces it. KB2563894 only updates two files (Tcpip.sys and Tcpipreg.sys). It does not update the 12 other affected ISATAP, UDP, and NUD .sys and .dll files. (MS11-064) KB2588516 addresses malformed continuous UDP packet overflow. But does not address the ISATAP related NUD and TCP .sys and .dll files. (MS11-083) So yes, many IP vulnerabilities. But each KB addresses specific issues that do not cross over to other KBs. We can install KB978338 by manually running the .MSU file, but we aren't certain if that will overwrite the couple files that get updated by later patches since we would be installing the patch out of order. Is the above analysis correct? Is the chain of supersession incorrectly defined? If it is, what is the proper way to report it so that it can be changed by the correct Microsoft team? We are currently using 32-bit and 64-bit installations of Vista SP2. Note: I should mention that I posted this on Technet as well. I will keep this up-to-date with any information I get on there.

• Getting 0xc00000e windows 7 "Boot device inaccessible" after random crashes

  - by Dynde

  I've been having some weird random crashes that I can't seem to locate, and I'm unsure if it's windows or hardware related. It's a brand new computer and very powerful. I've run into a couple of these random crashes, now I don't know what causes them, as it happens during the night, when I'm sleeping. When I wake up, all I see is a boot manager screen that says Exception: 0xc00000e "Boot device inaccessible". A simple restart doesn't fix the problem - it seems to struggle locating my primary hdd - but a complete shutdown works, it'll just fly straight into windows again. The event viewer doesn't tell me much. The most reason incident just gives me this: "The previous system shutdown at 08:55:44 on ?11-?12-?2011 was unexpected." And also a kernel power event: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. and I can see only two application event entries around that time at 8.47 (about 8 minutes prior to the crash): The Windows Modules Installer service entered the running state. The WinHTTP Web Proxy Auto-Discovery Service service entered the running state. Can anyone tell me anything about this, or direct me to a forum or something that might know what's wrong? I can supply the extra details of the events too if needed. The hdd is an SSD - could that have anything to do with it? I ran a few diagnostics and memory and hdd should be okay - at least the diagnostics report is clean. Is it a faulty drive?

• PHP Causing Segmentation Fault & Apache Blank Response

  - by Joe

  I recently updated a Debian Lenny server to php 5.3,5 using the dotdeb source. Soon after doing so certain (but not all) sites on the server stopped responding to requests. A blank response would be returned - no headers, no content, nothing. I found this related question on stackoverflow which seems to describe something similar and used the same code the user had in their answer to see if I could replicate the issue: <?php class A { public function __construct() { new B; } } class B { public function __construct() { new A; } } new A; print 'Loaded Class A'; ?> This triggered the problem - the page returned absolutely nothing despite the original question stating this was fixed in PHP 5.5.0. No CPU block as you'd expect, no wait, just an almost instant zero response. I then ran this same code from the cli (php -f test.php) and the only output I got was 'Segmentation fault'. Tailing the kernel log I've spotted: Feb 16 07:04:06 creature kernel: [192203.269037] php[17710] general protection ip:76ef37 sp:7fff155e9bb0 error:0 in php5[400000+870000] Feb 16 08:57:31 creature kernel: [199639.699854] apache2[31136]: segfault at 7fff13a84fe0 ip 7f730514ea40 sp 7fff13a85008 error 6 in libphp5.so[7f7304ce8000+915000] All extremely odd and I'm not sure what it's pointing to/what I should do to debug this further. As I said some sites work but code such as the above definitely trigger it. Not that the sites I want to server have code like that - it's just an example. Any help is much appreciated!

• Google Contacts/Calendars + Address Book + iCal: built-in sync (problems) or Exchange sync?

  - by jtbandes

  (I've looked at a few other questions related to this, but I've only found old questions with people saying that they're having problems, or anticipating Snow Leopard fixing them; no recent updates.) I'm looking to sync my Google Contacts & Calendars, and Gmail, with my Mac & iPhone. The iPhone I have currently set up thus: IMAP for Mail Exchange (Google Sync) for Contacts & Calendars The Mac: Address Book: built-in sync iCal: CalDAV, configured as a Google account I haven't been syncing Gmail to Apple Mail, because I was having weird IMAP glitches every so often that just got to annoying. Will Exchange / Google Sync work for this at all? Any suggestions there? Here are the other problems I'm having. Address Book only syncs certain fields (for example, Birthdays don't sync at all). I believe this is a list of the information that's synced. Address Book's "Synchronize with Google" checkbox doesn't stay checked when I quit Address Book. I think iCal is working fine, for the most part. Any suggestions on how to improve this setup? Why doesn't Address Book / Google Contacts sync stay enabled? Could I use Exchange for it like I am on the iPhone? Will that sync all the fields, including Birthdays, etc.? Thanks in advance!

• Shared configuration for Eclipse on Debian server

  - by Joris Meys

  I've manually installed the latest Eclipse on our debian server and wanted to configure it so all users share the same configuration. It turned out less obvious than I thought: I don't seem to be able to install packages for all users. If I run it myself, all configuration data is saved under my own home directory. If I run Eclipse using sudo, everything is saved under the root directory but is not accessible for other users when they run Eclipse. I've been browsing the manual of Eclipse and some forums, but apart from a "yes, you can" I couldn't find any information on how that should be done. The biggest problem is installing plugins for all users to be found. Any help is greatly appreciated. Eclipse : 3.6.1 classic, installed using this procedure. Server uname: GNU/Linux * 2.6.26-2-amd64 Server is accessed using Putty, and Gnome desktop through realVNC. Just mentioning it if that is of any importance. Our sysadmin is on "prolonged leave" (working in Spain and never replaced), so I'm stuck without help here. EDIT : -- I asked this question also on StackOverflow as I wasn't certain this is a genuine server-related question. Please feel free to merge both questions at the appropriate place. --

• Server 2008 Print Redirection is failing but only on 16Bit apps

  - by ian

  the main programmer for SoEasyAccounting and we are installing to Server 2008 Standard service pack 1. We install to 2003 with no problems. Important to understand that the print failure only happens in certain circumstances: Note: We use a standard Windows printer selection box to choose the printer Terms used Superbase = a program language that uses ntvdm.exe (Windows process hosting 16 bit apps) Local Printer = printing to a driver loaded onto the Server 2008 Redirect Printer = printing to a automatically established remote printer through an RDP connection Printing Scenarios Server 2008 - 1: Print from notepad to a Redirected Printer = works Server 2008 - 2: Print from Superbase to a Local Printer = works Server 2008 - 3: Print from Superbase to a Redirected Printer = fail Server 2003 - 4: Print from Superbase to a Redirected Printer = works Results The print causes a message in the drivers print queue of Local Downlevel Document, no print though and Superbase recognises that the "Print command failed". Eventvwr has no related issues to the print fail Any help greatly appreciated. So far 2 days spent trying to resolve and here goes my weekend :( unless someone has an idea :) Things I have Tried i. Switching on/off Easy print ii. Loading copy of redirected driver on server

• PHP displays blank white page even with all error reporting enabled

  - by Andy Shinn

  I am trying to debug a broken page in a Drupal application and am having a hard time getting PHP to spit anything useful out. I have the following set: error_reporting = E_ALL display_errors = On display_startup_errors = On log_errors = On error_log = /var/log/php/php_error.log I have a file showing me phpinfo() which confirms these variables are set correctly for the environment. I have increased memory_limit to 256M (which should be more than enough). Yet, the only indication I get is a status 500 code in the apache access log and a blank white page from PHP. The Apache virtual host has LogLevel set to debug and the error log only outputs: [Sat Jun 16 20:03:03 2012] [debug] mod_deflate.c(615): [client 173.8.175.217] Zlib: Compressed 0 to 2 : URL /index.php, referer: http://ec2-174-129-192-237.compute-1.amazonaws.com/admin/reports/updates [Sat Jun 16 20:03:03 2012] [error] [client 173.8.175.217] File does not exist: /var/www/favicon.ico [Sat Jun 16 20:03:03 2012] [debug] mod_deflate.c(615): [client 173.8.175.217] Zlib: Compressed 42 to 44 : URL /favicon.ico The PHP error log outputs nothing at all. kernel and syslog show nothing related to Apache or PHP. I have also tried installing suphp and checking its log just confirms the user is executing correctly: [Sat Jun 16 20:02:59 2012] [info] Executing "/var/www/index.php" as UID 1000, GID 1000 [Sat Jun 16 20:05:03 2012] [info] Executing "/var/www/index.php" as UID 1000, GID 1000 This is on Ubuntu 12.04 x86_64 with the following PHP modules: ii php5 5.3.10-1ubuntu3.1 server-side, HTML-embedded scripting language (metapackage) ii php5-cgi 5.3.10-1ubuntu3.1 server-side, HTML-embedded scripting language (CGI binary) ii php5-cli 5.3.10-1ubuntu3.1 command-line interpreter for the php5 scripting language ii php5-common 5.3.10-1ubuntu3.1 Common files for packages built from the php5 source ii php5-curl 5.3.10-1ubuntu3.1 CURL module for php5 ii php5-gd 5.3.10-1ubuntu3.1 GD module for php5 ii php5-mysql 5.3.10-1ubuntu3.1 MySQL module for php5 So, what am I missing here? Why no error reporting?

• conflicting info about the running kernel version in FreeBSD

  - by John

  I asked a related question about uname before, now want to ask from another angle because the following simple yet obvious conflicting outputs may mean there is something many people did not think of (me included). I'm running FreeBSD 9 RELEASE, please see the following commands: # sysctl kern.bootfile kern.bootfile: /boot/kernel/kernel # strings /boot/kernel/kernel |grep RELEASE|grep 9 @(#)FreeBSD 9.2-RELEASE-p7 #0: Tue Jun 3 11:05:13 UTC 2014 FreeBSD 9.2-RELEASE-p7 #0: Tue Jun 3 11:05:13 UTC 2014 9.2-RELEASE-p7 The above kernel file suggests the running kernel is 9.2-RELEASE-p7. But... # dmesg Copyright (c) 1992-2012 The FreeBSD Project. Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 The Regents of the University of California. All rights reserved. FreeBSD is a registered trademark of The FreeBSD Foundation. FreeBSD 9.1-RELEASE #0 r243825: Tue Dec 4 09:23:10 UTC 2012 ... # uname -a FreeBSD localhost.localdomain 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243825: Tue Dec 4 09:23:10 UTC 2012 [email protected]:/usr/obj/usr/src/sys/GENERIC amd64 So dmesg and uname says it's 9.1-RELEASE. I also did an extensive find / -type f -exec grep -l "9.1-RELEASE" {} \; but found no possible kernel file that contains 9.1-RELEASE. What could lead to the above conflict, and what kernel I am actually running? Please note I run RELEASE and ran freebsd-update to do binary update, so no compiled kernel is involved. And I have rebooted multiple times after freebsd-update. And the system is not in jail etc, just the only system on that computer.

• Own server, multiple website: most secure PHP setup

  - by plua

  Hi there, We have a company server with a variety of websites. They are maintained by different people from within our company. All websites are public. The server access is limited to our company only. This is NOT a shared hosting environment. We are looking into securing the server, currently analyzing the risk related to permissions of files. We feel the highest risk is when files are uploaded and then opened/executed by the public. This should not happen, but an error in a script might allow people to do so (there are image uploaders, file uploaders, etc). Uploader scripts use PHP. So the question is: what is the best way of setting / organizing permissions of files and processes? There seem to be several options to run PHP (and Apache), and setting the permissions. What should we take into consideration? Any tips? We are considering mod_php and FastCGI, but perhaps given our situation other solutions are preferred?
