• ProFTPD / PAM issues with new centos/virtualmin install

  - by iamthewit

  Hi All, I just installed CentOS 5.4 on a rackspace cloud server and installed virtualmin which all seemed to go fine. The only problem I have is that I can not access the virtual servers directories via FTP. I get the following from filezilla: Status: Connecting to 1.1.1.1:21... Status: Connection established, waiting for welcome message... Response: 220 FTP Server ready. Command: USER username Response: 331 Password required for username.

I do like to know exactly why problems occur though and how exactly to fix them so the more detail the better! cheers

• Ubuntu upgrade process failed

  - by Spin0us

  I tried to dist-upgrade my ubuntu server on my percona cluster but it failed with this message The following packages have unmet dependencies: libmysqlclient18 : Depends: libmariadbclient18 (= 5.5.33a+maria-1~precise) but it is not installable And here is the package listing # dpkg --list | grep -E 'percona|mysql' ii libdbd-mysql-perl 4.020-1build2 Perl5 database interface to the MySQL database iU libmysqlclient18 5.5.33a+maria-1~precise Virtual package to satisfy external depends ii mariadb-common 5.5.33a+maria-1~precise MariaDB database common files (e.g. /etc/mysql/conf.d/mariadb.cnf) ii percona-xtrabackup 2.1.5-680-1.precise Open source backup tool for InnoDB and XtraDB ii percona-xtradb-cluster-client-5.5 5.5.31-23.7.5-438.precise Percona Server database client binaries ii percona-xtradb-cluster-common-5.5 5.5.33-23.7.6-496.precise Percona Server database common files (e.g. /etc/mysql/my.cnf) ii percona-xtradb-cluster-galera-2.x 157.precise Galera components of Percona XtraDB Cluster ii percona-xtradb-cluster-server-5.5 5.5.31-23.7.5-438.precise Percona Server database server binaries ii php5-mysql 5.3.10-1ubuntu3.8 MySQL module for php5 During the install of the server, mariadb and galera cluster have first been installed.

• HTTP Error: 413 Request Entity Too Large

  - by Torben Gundtofte-Bruun

  What I have: I have an iPhone app that sends HTTP POST requests (XML format) to a web service written in PHP. This is on a hosted virtual private server so I can edit httpd.conf and other files on the server, and restart Apache. The problem: The web service works perfectly as long as the request is not too large, but around 1MB is the limit. After that, the server responds with: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>413 Request Entity Too Large</title> </head><body> <h1>Request Entity Too Large</h1> The requested resource<br />/<br /> does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit. </body></html> The web service writes its own log file, and I can see that small messages are processed fine. Larger messages are not logged at all so I guess that something in Apache rejects them before they even reach the web service? Things I've tried without success: (I've restarted Apache after every change. These steps are incremental.) hosting provider's web-based configuration panel: disable mod_security httpd.conf: LimitXMLRequestBody 0 and LimitRequestBody 0 httpd.conf: LimitXMLRequestBody 100000000 and LimitRequestBody 100000000 httpd.conf: SecRequestBodyLimit 100000000 At this stage, Apache's error.log contains a message: ModSecurity: Request body no files data length is larger than the configured limit (1048576) It looks like my step #4 didn't really take, which is consistent with step #1 but does not explain why mod_security appears to be active after all. What more can I try, to get the web service to receive large messages?

• postfix smtp_fallback_relay for deferred messages to a single domain

  - by EdwardTeach

  I use Postfix to send messages to a mail server outside my organization which frequently rejects/defers my mail. My Postfix server sees that these messages are deferred and tries again, eventually getting through. Final delivery can take up to an hour, which makes my users unhappy. In comparison, mail from my Postfix server to other hosts works normally. I have now found out about a second, unofficial MX for this domain that does not reject/defer mail. This second MX does not appear when doing a DNS MX query for the domain. Therefore, for the problem domain I would like to use this second MX as a fallback. That is: whenever mail is deferred by the primary MX, try again on the unofficial second MX. I see that there is already a postfix configuration "smtp_fallback_relay". However the documentation seems to indicate that I can not restrict usage of the fallback to a single domain. The documentation also doesn't mention deferred message handling. So is there a way to configure a single-domain, deferred-retry fallback host in Postfix? For reference, I am including my postconf output (the host names and ip addresses are fake): alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases, hash:/etc/postfix/legacy_mailman, ldap:/etc/postfix/ldap-aliases.cf append_dot_mydomain = no biff = no config_directory = /etc/postfix default_destination_concurrency_limit = 2 inet_interfaces = all inet_protocols = all local_destination_concurrency_limit = 2 local_recipient_maps = $alias_maps mailbox_size_limit = 0 mydestination = myhost.my.network, localhost.my.network, localhost, my.network myhostname = myhost.my.network mynetworks = 127.0.0.0/8, [::ffff:127.0.0.0]/104, [::1]/128, 10.10.10.0/24 myorigin = my.network readme_directory = no recipient_delimiter = + relay_domains = $mydestination relayhost = smtp_fallback_relay = the.problem.host smtp_header_checks = smtpd_banner = $myhostname ESMTP $mail_name virtual_alias_maps = hash:/etc/postfix/virtual

• computer build for extreme tabbed browsing

  - by David Berger

  I'm interested in building or buying a task-specific computer for my brother. His requirements are ridiculously simple: the machine has to be able to wait in hundreds of web-based virtual waiting rooms at once and not crash. To be competitive, he needs to be able to enter the waiting rooms an dauto-refresh them faster. My question is, what priority do I give the different specs? My initial surmise is this: Connection speed (nothing to do with my build, but I kind of think this will be more beneficial than anything I build for him) Memory size -- I don't usually see firefox taking up more than a gig, even when heavily tabbed, but I think one gig for the operating system and two gigs for the browser are necessary. Processor speed -- I think the processor will affect performance, but even something out of date will do what he needs Memory speed/RAM bus -- I doubt this will matter much, but it seems just on this side of irrelevant. Everything else is a non-issue for him. Does this seem to stack up correctly? Also, since he's looking to stay on the cheaper side, and I might end up recommending a refurb to him, is there anything particularly egregious that Vista would do if it came pre-installed? If I build it myself, I'll give him linux, but if I have it shipped to him, I'm not sure I could walk him through the install process for linux, but I probably could walk him through the process to upgrade to Windows 7, if it were somehow worth it.

• administrator user unable to login, suspicious user accounts "sky$", "admin$"

  - by mks

  I have a Windows 2008 R2 Standard (64 bit) running in a virtual machine. Suddenly from yesterday onwards I am not able to login as administrator. Nobody changed the password. Both in the console as well as using remote desktop I am unable to login. Whenever I login as Administrator I am getting this error: "The user name or password is incorrect" Nothing has changed in the machine and I have logged in the past successfully both through console and via remote desktop several time on the same machine. One strange behaviour I noticed is, I am seeing some additional user accounts if I try to login as other user. The suspicious user account are: sky$ admin$ SUPPORT_388945a0 Is it created by some malware/virus? Or is it some windows hidden account? Microsoft site says that SUPPORT_388945a0 is: The Support_388945a0 account enables Help and Support Service interoperability with signed scripts. This account is primarily used to control access to signed scripts that are accessible from within Help and Support Services. Administrators can use this account to delegate the ability for an ordinary user, who does not have administrative access over a computer, to run signed scripts from links embedded within Help and Support Services. These scripts can be programmed to use the Support_388945a0 account credentials instead of the user’s credentials to perform specific administrative operations on the local computer that otherwise would not be supported by the ordinary user’s account. When the delegated user clicks on a link in Help and Support Services, the script executes under the security context of the Support_388945a0 account. This account has limited access to the computer and is disabled by default. However I am not sure from where this "admin$" and "sky$" came. Anyone has similar experience?

• Connection refused in ssh tunnel to apache forward proxy setup

  - by arkascha

  I am trying to setup a private forward proxy in a small server. I mean to use it during a conference to tunnel my internet access through an ssh tunnel to the proxy server. So I created a virtual host inside apache-2.2 running the proxy, the proxy_http and the proxy_connect module. I use this configuration: <VirtualHost localhost:8080> ServerAdmin xxxxxxxxxxxxxxxxxxxx ServerName yyyyyyyyyyyyyyyyyyyy ErrorLog /var/log/apache2/proxy-error_log CustomLog /var/log/apache2/proxy-access_log combined <IfModule mod_proxy.c> ProxyRequests On <Proxy *> # deny access to all IP addresses except localhost Order deny,allow Deny from all Allow from 127.0.0.1 </Proxy> # The following is my preference. Your mileage may vary. ProxyVia Block ## allow SSL proxy AllowCONNECT 443 </IfModule> </VirtualHost> After restarting apache I create a tunnel from client to server: #> ssh -L8080:localhost:8080 <server address> and try to access the internet through that tunnel: #> links -http-proxy localhost:8080 http://www.linux.org I would expect to see the requested page. Instead a get a "connection refused" error. In the shell holding open the ssh tunnel I get this: channel 3: open failed: connect failed: Connection refused Anyone got an idea why this connection is refused ?

• Maximum limit of filepointer in php reached and not changeable

  - by mlaug

  I have a server with the current 5.3.x version installed. Since we are running a really simple and small server in php using sockets, that connects to a lot clients using sockets we need to raise the open file limit that has been already done on the server for the user, that runs the server #ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 29879 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 8192 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 29879 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited and we compiled php with --enable-fd-setsize=8192 still we are getting [19-Nov-2012 09:24:23 Europe/Berlin] PHP Warning: socket_select(): You MUST recompile PHP with a larger value of FD_SETSIZE. It is set to 1024, but you have descriptors numbered at least as high as 1024. --enable-fd-setsize=2048 is recommended, but you may want to set it to equal the maximum number of open files supported by your system, in order to avoid seeing this error again at a later date. once in a while in our logs. Anyone knows who to configure the unix server and php correctly to have that working? I found a bug, but that is related to 2006 and marked as "not a bug" https://bugs.php.net/bug.php?id=37025&edit=1

• Running Debian as guest operating system on a Hyper-V VM

  - by kce

  Hello. Layer-9 considerations are prompting a migration from Citrix XenServer to Hyper-V as our shop's virtualization platform of choice. This will require me to migrate our existing virtual machines from XenServer to Hyper-V. A hand full of these VMs are running Debian. Unfortunately, Debian does not seem to be on the list of approved/supported guest operating systems. In fact it seems that running Debian as a guest operating system of is rather difficult, although apparently not impossible. I have two interrelated questions: Does anyone have any experience running a Debian guest on Hyper-V? Is it one of those things where it just will not work at all or is more along the lines of "it will probably work fine, but we won't support it". Any experience here, positive or negative, would be helpful. How much of a bad idea is it to deviate from Hyper-V's list of supported guest operating systems? Again, is it either basically asking for Bad Things (TM) to happen or is just another instance of "it will probably work fine, but we won't support it"? Or is it somewhere in the middle? Thank you.

• how would it be possible to discover a cable modem's MAC remotely?

  - by amateurenthusiast

  i was reading the back archives of a canadian privacy law blog, and he linked to a judicial decision. apparently as part of an investigation in which were used yahoo chat and google's old 'hello' image trading program the officer was able to determine a suspect's modem's MAC address: In order to determine who STEPHTOSH was, the officer did a trace on a programme called WHO IS in an effort to learn from where STEPHTOSH was coming. WHO IS is a command program available to the public. The officer was able to ascertain that the person using the name STEPHTOSH was a Rogers Internet customer. The officer was able to obtain the Internet Protocol address, also known as the I.P. There is only one location for an I.P., which is unique to that subscriber. By use of the website known as DNS STUFF.com, one is able to find with which company this I.P. is registered. It was ascertained that the I.P. address used by STEPHTOSH was registered to Rogers Cable, from the Toronto area. The officer also learned the Cable Modem MAC address used by STEPHTOSH. This was all the information the officer was able to amass. now it was my understanding that the MAC address of any given device can only be accessed if you're only one 'hop' away on the Internet. the suspect in question was in Markham and the officer part of the Toronto Police, so it's conceivable that they both might have used Rogers internet. but would that still put them only one 'hop' away from each other? i thought the first hop after the modem was usually the ISP? and if he'd used a netBIOS query against this guy's machine it would return the ethernet card's MAC, not the modem's. so is this guy on the same rogers subnet as the suspect's cable modem, is that functionality part of google's Hello (i could only think that it would be possible if Hello operated as a virtual LAN or something), does the officer have remote access to the arp caches of the routers at Rogers or is he just full of crap and lying to make his case stronger?

• Why can't I update Adobe Creative Suite?

  - by Lynda

  I am attempting to check for updates using the Adobe Application Manager on Windows 8 and I get this error: The update server is not responding. The server might be offline temporarily, or the Internet or firewall settings may be incorrect. I have seen this error before on Windows 7 and remembered that I needed to disable the Microsoft Virtual WiFi Miniport Adapter. I navigated to the correct place but the Miniport Adapter was not there. After a bit of searching across several forums I saw a recommendation to change <logLevel>2</logLevel> to <logLevel>10</logLevel>. I attempted that and again it still did not work. I have also tried disabling my anti-virus protection and disabling Windows Firewall. Neither worked. I am not sure what else to try or do at this point. Are there any other recommendations to solve this issue? Notes: I am running Windows 8 Pro using the Creative Cloud Version of CS6. I check for updates by choosing Help Updates from within any Adobe Application This issue was not present in Windows 7 before I upgraded to Windows 8 I originally posted this question on the Adobe Forums and received no help there.

• SQL 2008 SP1 crashing almost daily

  - by matijake

  Hey, almost every day our new DB crashes. It is virtual server residing on same hardware as 5 other servers, two of them beeing identical MS SQL2008sp1 and two Oracle 11g's so I can pretty much rule out hardware issues. Server has dedicated local LUN, 4vCPU and 8GB memory with 2GB windows swap file. It runs 4 instances. Primary instance is limited to 5GB memory and paralelism set to 4 running on MS SQL 2008 SP1 @ Windows Server 2008 Enterprise R2 x64. Only that primary instance is crashing. After it crashes nothing can connect to it, it's even impossible to shut it down through service manager. What I found in logs is: ***Stack Dump being sent to C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\LOG\SQLDump0081.txt SqlDumpExceptionHandler: Process 4788 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server i s terminating this process.     Whole log can be seen at: http://kabl.org/files/SQLDump0081.txt second crash log made second later at: http://kabl.org/files/SQLDump0082.txt I have analyzed mini crashdump with Microsoft tools, but no promising results. If it can help, here it is: http://kabl.org/files/SQLDump0081.mdmp Any ideas are greatly welcome, since it is becoming quite a pain in the ass to restart server almost every day :) Regrads, -Matija

• Network card very slow, only on Windows

  - by J Penguin

  This only happens to 1 of my machine, and only when booting into Windows 7. No matter what network card I put in, Windows would default its mode to 10Mbps full duplex. Transfer speed is approximately 1 MB/s. If I set it to 100Mbps, the transfer drops to 100-200K/s. If I set it to 1000Mbps, the connection is lost completely. I've tried swapping in different cards, both PCI-E and PCI. I'v etried update the windows, I've tried reinstalling the drivers... On this very same machine, if I boot into Fedora, it can use the card at its full capacity 1000Mbps transfering 80+ MB/s And all the cards work just fine when plugging into other machines on the same network. I'm very curious. What could be the reason for this? The only different software that this machine has is virtual box with a VPN emulator, but disabling that VPN doesn't seem to do anything. I would like to get this fixed, hopefully, without reinstalling windows _< Will that be possible?

• chkconfig creating service symlinks with the wrong order

  - by Robert

  On RHEL 6.3, I have a system service that should be starting after postgresql and httpd (order 64 and 85, respectively), but chkconfig always places it at order 50. I tried an experiment on a CentOS 6.0 virtual machine to make sure I understood the LSB stanza syntax. I created /etc/init.d/foo, owner root, permissions 755, with this text: ### BEGIN INIT INFO # Provides: foo # Required-Start: postgresql httpd # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Description: Foo init script ### END INIT INFO And then ran chkconfig --add foo. Result: /etc/rc5.d/S86foo is created, as expected. (The other runlevels are also as expected.) I repeated the exact same experiment on the RHEL machine, and it created /etc/rc5.d/S50foo instead. I can't see anything different between the two that would lead to different results. Both machines have postgresql and httpd starting at the same orders and runlevels. Any thoughts? I could just use # chkconfig: 2345 86 50, or manually rename the service symlinks to the correct order, but I'm trying to document an install process for later users, and I want to know how to do it right and understand why it's not working as expected.

• DAS vs SAN storage for serving 2 to 4 nodes

  - by Luke404

  We currently have 4 Linux nodes with local storage, arranged in two active/passive pairs with storage mirrored using DRBD, running virtual machines (actually using Xen Hypervisor) for typical hosting workloads (mail, web, a couple VPS, etc.). We're approaching the (presumed) maximum IOPS of those servers, and we're planning to migrate to an external storage solution with two active nodes, with capacity for up to four active nodes. Since we're an all-Dell shop I've done some research and found the MD3200 / MD3200i products should be the ones we're looking for. We are pretty sure we won't be attaching more than 4 hosts on a single storage and I'm wondering if there is any clear advantage for one or the other. In theory I should be able to attach 4 SAS hosts to a single MD3200 (single links on a single controller MD3200, or dual redundant SAS links from each host to a dual-controller MD3200), or 4 iSCSI hosts to a single MD3200i (directly on its 4 GigE ports without any switch, again with dual links for the dual controller option). Both setups should let us implement live VM migration since all hosts can access all the LUNs at the same time, and also some shared filesystem like GFS2 or OCFS2. Also, both setups should allow full redundancy of the whole system (assuming dual controllers in the storage). One difference I can see is that the DAS solution is actually limited to 4 hosts while the iSCSI one should be able to grow to more hosts (adding two GigE switches to the mix). One point for the iSCSI solution is that it would allow us to start out with our current nodes and upgrade them at a later time (we can't add other SAS controllers, but they already have 4 GigE ports each). With the right (iSCSI|SAS) controllers I should be able to connect diskless nodes and boot them off the external storage which I think is a good thing (get rid of any local storage). On the other hand, I would have thought the SAS one to be cheaper but it seems like an MD3200 actually costs a little less than an MD3200i (?) (please note: I've used Dell gear in my examples since that's what we're looking for but I assume the same goes with other vendors) I would like to know if my assumptions above are correct, and if I'm missing any important difference between the two setups.

• Ubuntu Wubi "drive" failure; mount drive in XP?

  - by 618034

  Hi there, I installed the Wubi distribution of Ubuntu on a separate partition (which is silly, since why do I care if Windows can still manage the partition?) a few months back; it was pretty awesome, until Linux hosed. At this point, I can get Ubuntu to boot if I try really hard through grub, but once it does start, the screen is hosed, so no dice. At this point, I'd like to wipe it all and start over, but I need to get some stuff off the "disk". The Wubi install makes this difficult, since the "disk" is a flat file on an NTFS partition. I've done just about everything I can think of — I renamed the virtual disk .iso, mounted it with VirtualCloneDrive, then used whatever magic EXT3 (EXT4?) readers I could dig up on the Internet to parse the mount — but nothing's working. Can you offer any suggestions? The "disk" is currently in D:\ubuntu\disks\root.iso. Many thanks! (I may be high-latency at the moment, apologies if I don't address follow-ups quickly)

• Update BIOS on Sun Fire X4150 server

  - by Massimo

  I have some Sun Fire X4150 servers with a very old BIOS release (1ADQW015), which seems to have some compatibility problems with WMware ESX Server 3.5 and Windows 2008 R2 virtual machines; so I want to update the BIOS on them. The problem: according to this page, if your servers run ELOM (mine do), you first need to update to the latest ELOM release, then to the interim transition release, then finally you can update to the latest one. Ok, I'm willing to do that... but it looks like Sun (now Oracle) will happily let you download the latest firmware DVD (3.3.0), but it will not let you download the transition release (2.0) if you don't have a support contract. Well, I actuall don't care at all about the servers' management controllers (we don't even use them), so upgrading from ELOM to ILOM is totally irrelevant to me; but I need to update the servers' BIOS. So my question is: can I update the servers' BIOS to the latest version without doing the full ELOM-to-ILOM migration, or will this not work (or even make the servers unusable)? Do BIOS versions and SP ones need to be matched, or can one be updated without bothering with the other? Bonus question: if this whole ELOM-to-ILOM thing actually is needed in order to update the BIOS, can that 2.0 CD-ROM be obtained without having a support contract with Sun/Oracle (which we are definitely not going to sign, being that quite old hardware)? Update: I tried upgrading only the BIOS on one of the servers, and it didn't boot anymore. So it really looks like a full firmware upgrade is needed, and the management controller and BIOS versions should be kept in sync. So... where can I find that *&!£%$% 2.0 CD-ROM? Or at least the transition firmware that can be found on it?

• How does it hurt to use Linux (Ubuntu) as a guest OS for all my tasks?

  - by sauparna

  I have a machine running Windows, where the disk has two partitions C (50 GB) and D (250GB). I do research in Information Retrieval and need to work with a large corpus (more than 50 GB) and in Linux. So if I want to install Linux on the existing system, keeping the Windows installation intact, will it be fine to run it in a virtual box? (say, QEMU, VMWare, etc.) An alternative is using Wubi. In that case the Linux installation has to be on drive C. Then, if I keep a small Linux installation (say 5GB) on C, and my corpus on D (mounted in Linux), how will it affect the performance of my programs which would be accessing the mounted Windows drive D. Is it feasible to use Linux this way? Which of the above is better if at all they are a way out? Note : Since my post in July 2010, I have been using and have tried several ways of maintaining a disk-image that I can mount in Linux. I had a 100GB qcow2 disk and a 100GB raw disk, both formatted to an EXT3 file system. I was mounting and connecting to the qcow2 disk using qemu-nbd. The problem was that every now and then, the connection to the disk would get lost and the running programs would throw disk I/O errors. The raw disk would mount and work fine as a loop mounted device, but when writing data to it, the mount.ntfs program would hog the CPU and the process would take an enormous amount of time. I was in fact running make on a piece of software located on this raw disk, and after a point of time make was waiting while mount.ntfs would show 100% CPU usage.

• No apparent reason for high load average

  - by Oz.

  We have several web servers running on Amazon (ec2) c1.xlarge, over Amazon AMI. The servers are duplicates of each other, running the exact same hardware and software. Each server spec is: 7 GB of memory 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each) 1690 GB of instance storage 64-bit platform I/O Performance: High API name: c1.xlarge A couple of weeks ago we have run a yum upgrade on one of the servers. Starting on this upgrade the upgraded server started showing a high load average. Needless to say, we did not update the other servers and we can not do so until we understand the reason for this behavior. The strange thing is that when we compare the servers using top or iostat, we can not find the reason for the high load. Note that we have moved traffic from the "problematic" server to the others, which have made the "problematic" server less crowded in terms of requests, and still his load is higher. Do you have any idea what could it be, or where else can we check? Many thanks for the help!

• Cannot Update Adobe Creative Suit

  - by Lynda

  I am attempting to check for updates using the Adobe Application Manager on Windows 8 and I get this error: The update server is not responding. The server might be offline temporarily, or the Internet or firewall settings may be incorrect. I have seen this error before on Windows 7 and remembered that I needed to disable the Microsoft Virtual WiFi Miniport Adapter. I navigated to the correct place but the Miniport Adapter was not there. After a bit of searching across several forums I saw a recommendation to change <logLevel>2</logLevel> to <logLevel>10</logLevel>. I attempted that and again it still did not work. I have also tried disabling my anti-virus protection and disabling Windows Firewall. Neither worked. I am not sure what else to try or do at this point. Are there any other recommendations to solve this issue? Notes: I am running Windows 8 Pro using the Creative Cloud Version of CS6. I check for updates by choosing Help Updates from within any Adobe Application I originally posted this question on the Adobe Forums and received no help there.

• Active Directory + IIS + SQL + ASP.NET

  - by Amira Elsayed Ismail

  I have sent the following question to stackoverflow website I have installed Windows server 2008 r2 on a virtual machine, Can I install Active directory with domain controller + IIS + SQL server on the same machine? I want to make web application and this web application will authenticate users from Active Directory, the web application should be published on the server IIS and the users should access it remotely from their home using domain name of my machine, Someone tell me that its very wrong to have IIS and Active directory on the same machine I got the following Answer You can't use ActiveDirectory over the internet. At least not without something like a VPN as a middle man. Their home computers will not be joined to the domain, so there is no pass-through authentication. Yes, it's a bad idea to put AD on the web server. Why is too complex to get into in an answer here. Suffice it to say that even if you did do this, it's probably would not work the way you are thinking it should. It's not impossible to do this. For instance, many of the Microsoft "Small Businesss" products put IIS, AD, and SQL Server on the same server. But, you kind of have to know what you're doing to configure it securely. Then I add the following comment Thanks for ur reply.so what you think about the best way to do this as I didn't do anything like that before should I install active directory on a machine and IIS on another machine ? and what about SQL should I add it to the same server of active directory ? I didn't mentioned also that it will be Microsoft dynamics server that will access some information about work and i have to read data from axapta also ? also what is VPN and how can I use it to let users access my web application anywhere ? Sorry for my long questions and thanks in advance so please if anyone can help I will be thankful

• Java VM problem in OpenVZ

  - by Ginnun

  Hi, I bought a vps for hosting my java needs. But I can't run java on it. Everything about java is correctly installed but when I try to run java ("java -version" forexample) I get this error : Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. I don't think this is a java centered problem, Out of memory for sure. I contacted the vps admin, but he says everything is fine, you have 2gb ram, expandable to 4gb! I did a bit search on the subject, here is my BEANS file (numbers converted to humanredable form using a script). By the way do JVM heap memory allocs count on kmemsize or privvmpages ? How much ram does that configuration allows me to allocate with jvm for a single process? resource held maxheld barrier limit failcnt kmemsize 2.25 mb 2.35 mb 13.71 mb 14.10 mb 0 lockedpages 0 0 1024.00 kb 1024.00 kb 0 privvmpages 20.54 mb 21.33 mb 256.00 mb 272.00 mb 156 shmpages 5.00 mb 5.00 mb 84.00 mb 84.00 mb 0 numproc 13 14 240 240 0 physpages 9.36 mb 9.45 mb 0 MAX_ULONG 0 vmguarpages 0 0 132.00 mb MAX_ULONG 0 oomguarpages 9.36 mb 9.45 mb MAX_ULONG MAX_ULONG 0 numtcpsock 3 3 360 360 0 numflock 3 3 188 206 0 numpty 2 2 16 16 0 numsiginfo 0 1 256 256 0 tcpsndbuf 69.17 kb 69.17 kb 1.64 mb 2.58 mb 0 tcprcvbuf 48.00 kb 48.00 kb 1.64 mb 2.58 mb 0 othersockbuf 6.80 kb 6.80 kb 1.07 mb 2.00 mb 0 dgramrcvbuf 0.00 kb 0.00 kb 256.00 kb 256.00 kb 0 numothersock 9 10 360 360 0 dcachesize 0.00 kb 0.00 kb 3.25 mb 3.46 mb 0 numfile 704 746 9312 9312 0 numiptent 10 10 128 128 0 Thanks in advance!

• Cannot Access Shared Folder From IIS

  - by Tim Scott

  From IIS I need to access a folder on another computer. Both servers are Window 2008 SP2, and they live in a Virtual Private Cloud on Amazon EC2. They reach one another by private IP -- they are in WORKGROUP, not a domain. I can access the shared folder manually when logged in to the client as Administrator. But IIS gets "access denied." Here's what I have done: Set File Sharing = ON Set Password Protected Sharing = OFF Set Public Folder Sharing = ON Shared the folder Added permission to the share: Everyone, Full Control Added permission to the share: NETWORK SERVICE, Full Control Verified that File & Printer Sharing is checked in Windows Firewall Opened port 445 to inbound traffic from local sources I tried adding <remote-machine-name>\NETWORK SERVICE to the share but it says it does not recognize the machine, which makes sense, I guess. As I said, from the other computer I have no trouble accessing the shared folder from my user account, but IIS is shut out. How does the file server even know the difference? I would assume that with Everyone given full control and password protected sharing turned off, it would not matter what the client user account is. In any case, how to solve? UPDATE: To clarify, I am not trying to serve up files on the share directly through IIS. Rather I am writing files to the share from my code (System.IO).

• pfSense router on a LAN with two gateways

  - by JohnCC

  I have a LAN with an ADSL modem/router on it. We have just gained an alternative high-speed internet connection at our location, and I want to connect the LAN to it, eventually dropping the ADSL. I've chosen to use a small PFSense box to connect the LAN to the new WAN connection. Two servers on the LAN run services accessible to the outside via NAT using the single ADSL WAN IP. We have DNS records which point to this IP. I want to do the same via the new connection, using the WAN IP there. That connection permits multiple IPs, so I have configured pfSense using virtual IP's, 1:1 NAT and appropriate firewall rules. When I change the servers' default gateway settings to the pfSense box, I can access the services via the new WAN IPs without a problem. However, I can no longer access them via the old WAN IP. If I set the servers' default gateway back to the ADSL router, then the opposite is true - I can access the services via the ADSL IP, but not via the new one. In the first case, I believe this is because an incoming SYN packet arrives at the ADSL WAN IP, and is NAT'd and sent to the internal IP of the server. The server responds with a SYN/ACK which it sends via its default gateway, the pfSense box. The pfSense box sees a SYN/ACK that it saw no SYN for and drops the packet. Is there any sensible way around this? I would like the services to be accessible via both IPs for a short period at least, since once I change the DNS it will take a while before everyone picks up the new address.

• Windows 2012 RDS Temporary profile for Administrator

  - by Fabio

  I've configured a Windows 2012 RDS Farm with two virtual servers (VMWare - each one on a different ESX server). Both servers have Licensing, Web Access, Gateway, Connection Broker and Session Host roles. High Availability is set up and it works fine. Remote Apps are working and even Windows XP clients have access to the web interface. User profile path is \vmfiles1\UserProfileDisks\App\ and almost everyone has full right access to it. The problem I have is that I would like to be able to access both servers at the same time with the Administrator account (console), but each time I try, the second server that I logon to give me access with a temporary profile. I tried to enable/disable multiple sessions per user and forced Admin logoff with the GPO but nothing changed. Another thing is that the server pool is not saved, so each time I restart the RDS server or I logoff from it, I have to add a server in the server manager. Do you have any idea? Sorry if my english is not perfect.
