• cannot at all find sql instance (while installing an asp.net app on IIS)

  - by giddy

  So I'm really not a DBA, I'm an app dev. I had to install my asp.net mvc3 app on my client's(a large company) IIS6 + Win2k3 machine, with absolutely no help from their sysadmins. The final problem now is SQL Server 2008 r2, after figuring out how to create a login from windows, my app and sqlcmd.exe always complains it cannot find a sql server instance!! I have all the sql services (in services.msc) running to Log On as the local system. I can login fine with SQL Server Management Studio with Windows Auth. I created my database, my asp.net app needs/uses windows auth. But for the love of God, whatever I do my app always complains it cannot find the instance. (Also tried running SQL CMD and it complains of the same thing too!) My data base connection string looks like this: Data Source=machinename\username;Initial Catalog=myDataStore;Integrated Security=True;MultipleActiveResultSets=True Machinename\user is the same thing that shows up on the sql server management studio login if I choose windows authentication right?

• Remote Desktop Services create LAN and WAN user groups

  - by PHLiGHT

  I'm setting up one server with the gateway, server host and web access roles on it. I know that isn't ideal but I don't expect to have many simulatenous users. I want users to access remote desktop web access and connect to the server host via the gateway as outlined here which avoids opening 3389 to the internet. Users will be connecting from the LAN and the WAN. What I'm looking to do is to allow some users LAN access but not WAN access and added plus would be if security settings (such as no clipboard) would be different when accessing via the WAN. Is this possible? It seems all users can logon to remote desktop web access by default. They can't run the remoteapps once logged in though without the proper permissions. Can I prevent them from even logging into remote web access? Since they renamed it from terminal services to remote desktop services it has made my Googling a bit harder. Thanks!

• What's the difference between a normal ActiveX killbit update and one for IDX?

  - by Bob

  I'm looking back at some old MS security bulletin for distribution to new clients and when I look at downloads for the last set of MS ActiveX killbits, KB article here, under each platform I see links with the term IDX. For instance there will be an entry that says "For Windows 7 for 32-bit versions" and then one a few rows down that says "For Windows 7 IDX for 32-bit versions". What's the difference between the two? I understand from a little digging that idx is one of the field names for the database that ActiveX controls are stored in, but that's not really helpful.

• CentOS - Yum doesn't update anymore?

  - by Xanathos

  I've been trying to use yum now, but for some reason, not even the search work anymore. I even tried putting packages I already downloaded in the search criteria and is the same.

• Permission to see the expandable list of ISA Server 2006

  - by Hossein Mobasher

  I am working on ISA Server 2006 in Windows Server. I want to add some policy rules to my server, I followed this link. But It points to In the Microsoft Internet Security and Acceleration Server 2006 management console, expand the array name, and then click the Firewall Policy node. When I open the ISA Server 2006 Management Console, I can not show the expand list, how can I force ISA to show the expandable tree to start Firewall Policy? Could any one please help me to do this ? Note : I have administrator permission for my account. Thanks in advance :)

• RAID 1 not performing as expected

  - by Faken

  I recently bought a new 320Gb hard drive for my computer to set up RAID 1 on it for some added security. Installation went as smooth as could possibly be (plug in power, plug in data cable, start up computer, Intel software recognized new drive, right click create RAID 1, done!). However, for some inexplicable reason, I seem to have strange test results when using BENCH32. On my old configuration, a single 7200 rpm drive, I achieved about 60 MB/s write and 70 MB/s read. With a new RAID 1 configuration, I would expect the write to be slightly diminished but read to be significantly improved (though not exactly double speed). However, with the new configuration, I am getting 90 MB/s write and only about 80 MB/s read. I should NOT be getting improved write performance, especially NOT better than read! What's going on? My system setup is: q6600 2.4ghz CPU 4Gb DDR2 667mhz RAM on board Intel ICH9R "RAID chip" 2x Seagate 7200 RPM 320GB drives in RAID 1 Widows 7 home premium 64-bit

• users unable to add registry keys to HKCU

  - by Eds

  I may not have this 100% correct so need some clarification. Are normal users on a 2003 terminal server allowed to add registry keys the their own HKCU section in the registry, or are they only allowed to edit existing ones? The reason I ask is that we have 3 keys that we need to add for each user on login. I thought it would be as simple as having a straightforward batchscript run that silently adds the keys for the user. Here is what I used: regedit.exe "C:\Documents and Settings\All Users\Desktop\example.reg" When the user runs this batch scipt, they see nothing as you would expect, but the keys are not added. If I simply run the .reg file as the user, it asks if I want to add the key, but then has an error saying there was an error accessing the registry. Do I need something a bit more complex to accomplish this task. Many Thanks Eds EDIT: Contents of .reg file Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Policies\Microsoft\office\14.0\outlook\Security] "PromptSimpleMAPINameResolve"=dword:00000002 "PromptSimpleMAPIOpenMessage"=dword:00000002 "PromptSimpleMAPISend"=dword:00000002

• Will I have internet connection issues next day, if I unplug router at night?

  - by headskracher77

  I did this regularly a few years ago and used to feel like I was 'being punished' by the Interent svc provider for disabling access to my computer, because trying to re-connect the next day became a constant pain. I have the same linksys router, a comcast modem, and hi-speed broadband through their LAN. Question: who or what is at fault for lousy internet connections, slow connections, or no connections: (everybody's tech dept. blames everybody else) The router? 10 year olds, maybe obsolete? The modem? came with the service plan - can connect three devices on a sharedconnection. The ISP: I read they not only even control and completely regulate bandwidth usage, but they also ration it!! (true?) So can I safely 'pull the plug' each night for security or not? thnx

• recommendations for a lightweight linux distribution for a test server

  - by Jack

  I'm planning on setting up a test server to experiment with some application servers (tomcat/jboss/...) and with some portals. Now the machine I've set aside for this is lightweight CPU/GPU wise(Atom D510, 4 gigabyte ram, 500 GiB hdd, onboard GPU). But it should suffice for most things, I'm more interested in the stability of JBoss/Tomcat for my purposes than the stability. However I'm having a bit of trouble picking an appropriate distribution size/performance/setup time wise/security wise since it seems I can't sneeze without another distribution popping up. I've been thinking about going for Fedora since I've read that that distribution has been optimized for Atom, but I'm not really familiar with it. My experience with Linux has mostly been limited to Ubuntu and some tinkering with puppylinux. I'm not afraid to get my hands dirty using the command line. I'm not planning on starting a discussion per se, mostly the pros/cons that people have encountered with some distributions

• icacls, Network Service, and setting ACLs on Windows Server 2008

  - by Ted

  Setting ACLs on Windows Server 2008 via the command line is giving me some problems. As per http://web2.minasi.com/forum/topic.asp?TOPIC%5FID=26907 I've tried all sorts of variations: C:\Windows\system32icacls "D:\Websites\site.com\Web\bin*" /grant 'NT A uthority\NETWORK SERVICE: (OI) (CI)M' C:\Windows\system32icacls "D:\Websites\site.com\Web\bin*" /grant "NETWORK SERVICE": (OI) (CI)M And all variations in between. However, each try leads to i.e. "Invalid parameter "'NETWORK'"" depending on the variation above. As per http://technet.microsoft.com/en-us/library/cc753525%28WS.10%29.aspx (see in comments), it appears that others have experienced the same issue where the same command works on Windows 7/Vista/etc., but not on Windows Server 2008. What's the best way to apply permissions to Network Service account on a directory and/or files via the command line in Windows Server 2008? Especially as there's no way to do multiple file permissions at once via the GUI (see http://serverfault.com/questions/30991/windows-server-2008-change-security-settings-for-multiple-files-at-once).

• Are there other application layer firewalls like Microfot TMG (ISA) that do advanced http rules?

  - by Bret Fisher

  Since the old days ISA and now TMG have had several great features that I often want to deploy to my customers because of the enhanced functionality and security, but often the cost of an additinal server HW, Windows Server, and TMG license is too much to justify when compaired to a $300-500 appliance. Are there other gateway firewalls that can perform one or more of these application layer features: pre-auth incoming http traffic against AD/LDAP before sending packets to internal server (forms auth or basic creds popup)? read host headers of incoming http traffic (even on https) to a single public IP and route packets to different internal servers based on that host header?

• Remote Access Without Explicit Permission: Convenience or Liability?

  - by routeNpingme

  For outsourced professional IT remote support, one habit most new technicians get into is the "instead of getting the user to start up remote support each time, I'll go ahead and install LogMeIn / GoToMyPC / Remote Desktop / whatever so that if they call again, I can just jump on and help them". This of course opens up a potential liability because a client PC on a network that we don't own is being accessed without a user explicitly providing permission by clicking a "Yes, allow technician to control my PC" option. I realize the rules totally change when you're an IT admin over a network that you "own", but this is outsourced IT support. Just curious what others' policies are. Is this an acceptable practice for convenience and I'm turning into one of those "security is more important than anything" people, or is this really a liability?

• Sending large files - do any vendors sell their solution?

  - by Rob Nicholson

  We currently have an account with www.mailbigfile.com to allow us to send & receive files which exceed our client's email limits. In our industry, a 10MB limit is not unknown. Mailbigfile works fine for what it is but increasingly, our clients are starting to block it as a security risk. A solution would be for us to license the software and run it from our own web server which is far less likely to be blocked. Does anyone know of vendors in this market? We are looking at web collaboration systems but that's a much bigger project. The technology behind www.mailbigfile.com isn't that complex (http upload, email notification and then http download) so I'm hoping it won't be very expensive. Cheers, Rob.

• What is the right way to use Internet Sharing in OS X?

  - by Bob King

  For a while now I've been using the Wireless in my Mac Mini as a seperate WiFi access point because my main router doesn't quite cover my whole house. There is a dedicated CAT 5E line down to the Mini, which has a static IP address. I've turned Internet Sharing on, using Airport/WiFi but it seems my options for security are limited. Can I do WPA2? Also, it seems like my iPhone only connects 25% of the time, and the rest of the time it claims I've given a bad password. I've tried "Forget this network" repeatedly.

• how to start with unmanaged vps?

  - by GaVrA

  Hello! I have a managed VPS, so whatever i need i can just ask my support, and they will do it for me. Now i plan to migrate to unmanaged VPS, so i need some guides, tips on how and where to start learning. I will have more specific questions once i start using it, but now i just need some general answers about this topic. Thanks. Update: Ok, i have decided to go for unmanaged VPS with cPanel. OS is CentOS-5. I contacted support only for some small(i think) things like creating new account in whm, some database importing, installing new software(rare)... What i will be using is apache, php, mysql. I think i will be able to cope with upgrading to new versions, so the thing that interests me the most is security i guess.

• login as rsh in rhel 6 without entering password

  - by cartmancakes

  I need to be able to login to a RHEL 6 server using rsh (please don't flame me about security, it's irrelevant in this particular instance) as root without having to enter a password. My procedure for setting this up works great in RHEL 5.x, but does not work in RHEL 6. I suspect this has something to do with PAM, but I'm inexperienced with how to use PAM. Can someone help me with this? /etc/pam.d/rsh auth required pam_rhosts.so auth required pam_nologin.so account include common-account password include common-password session required pam_loginuid.so session include common-session /etc/pam.d/rlogin auth required pam_nologin.so auth [user_unknown=ignore success=ok ignore=ignore auth_err=die default=bad] pam_securetty.so auth sufficient pam_rhosts.so auth include common-auth auth required pam_mail.so account include common-account password include common-password session required pam_loginuid.so session include common-session Thanks!

• MSSQL: Choice of service accounts

  - by Troels Arvin

  When installing MS SQL Server 2008, one needs to associate a service account with the installation (possibly even several accounts, one for the SQL Server Agent, one for Analysis Services, ..., but let's leave that for the case of simplicity). The service account may be local account, or a Windows domain account. If a domain account is used: Can MSSQL start, if connectivity to the domain controllers is temporarily down? If the answer is yes: Should each DBMS instance on each server have a separate account, or does it make sense to use a particular "MSSQL" domain account on all MSSQL-installations in the organization? If separate accounts are used for each instance on each server: Does it make sense to create a special MSSQL security group in the domain and place all the MSSQL service accounts in that group, perhaps to ease replication, etc? Is there a common, generally accepted naming convention for MSSQL service account(s)?

• SSH reverse tunnel to monitor and manage remote devices

  - by acid_crucifix

  I have a set a distributed set of devices running Ubuntu 12.04 that I am distributing to clients. I would like to manage them remotely. They may not have fixed IPs and potentially might be behind firewalls. What I am planning to do is have the devices (permanently connected to the net) poll a request URL and based on the response open a reverse tunnel to my server, so that I can access them via that tunnel. Most of what I read about reverse tunnel over SSH is for single use cases and very little about heavy production usage. Is there some reason for this, security issues? or stability? Any help would be much obliged.

• Can't find a wireless access point's IP address after changing router IP/LAN settings

  - by flagg19

  I have a modem/router, Netgear DG834, and a wireless access point (AP), Netgear WG602. The AP is directly connected to the router. My old working configuration was: Router IP address : 192.168.0.1 Access point IP address: 192.168.0.10 My new configuration is: Router IP address : 192.168.1.1 Access point IP address: ???.???.???.??? I changed my router's IP address/LAN settings to set up a VPN with another Netgear router that had the same LAN configuration. The wireless network is still up and perfectly working, but I can't find the AP's IP address. I've tried broadcast ping but the AP won't respond. I looked at the router "attached devices", but it's not there. I've played around with Nmap and arp request but the AP is totally invisible. I can fix it by resetting it to factory settings, but I'm very interested in learning more about this problem. I'm also interested in network security and this fact of having an invisible AP well, it's something I'd like to understand.

• how to change the default open-with program to a program on the second disk

  - by Scott????

  I have a 250GB HDD for my system and a 60GB SSD using a SATA port. I installed most of my applications on the SSD. There's a strange thing though. I can not change the default open-with program to a program which is on the SSD. I think it may be caused by permission so I gave my user a 'full control' permission on the security tab in disk properties. But changing permissions is not work. After I choose an application (I've tried Notepad++, Sublime, 7Zip, etc.), nothing is added in the below window: Also, if I install 7Zip on my machine, the right click menu items can not be added.

• Are less domains better than more domains in active directory?

  - by johnny

  A colleague of mine wants to add a domain to our forest. He said it would be good for security. I believe him but I have no idea why it is any better than with just one domain. I read this on Wikipedia but it has no source: "Microsoft recommends as few domains as possible in Active Directory and a reliance on OUs to produce structure and improve the implementation of policies and administration." I have no idea if it's right or not. I was hoping for comments. Thank you.

• Have to reset wireless frequently on iPad / Macs connected to Cisco WRV200

  - by retailevolved

  I have a Cisco WRV200 set up in our small office. The wireless signal works great for PCs, but I have found that Macs and iPads have to frequently reset the connection. It will be working for about 10 minutes, then stop. To fix it, I just turn off Airport and turn it on again. On an iPad, I have to go into settings, shut the wireless off, and then turn it on again. The router is broadcasting mixed B/G on channel 6. Security is WPA-PSK2. Anybody out there had similar issues with their router? How can I fix it?

• no UAC prompt when opening the Services applet

  - by Serge - appTranslator

  Not quite sure if this question is better asked here or on superuser.com Hi All, My Win7 Ultimate no longer 'UAC prompts' me when I open the services applet (administrative tools). I can manipulate services without ever confirming the elevation. Yes, UAC is still enabled. Yes, I've rebooted to make sure this is not due to a former UAC elevation of explorer.exe or so. It looks like a big security hole. Does anyone have an idea about the reason for this behaviour? Or how to investigate it? TIA,

• Why doesn't phpMyAdmin connect to MySQL server?

  - by Grafica

  I'm running xampp on Windows 7, and when I type localhost/phpmyadmin, there is an error: phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server. Here's what I did, but I'm still not able to connect: In config.inc.php, changed from true to false: $cfg['Servers'[$i]['AllowNoPassword'] = false; Changed password here: localhost/security/xamppsecurity.php In resetroot.bat, typed new password where it says 'password': echo REPLACE INTO user VALUES ('localhost', 'pma', 'password', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', 'N', '', '', '', '', 0, 0, 0, 0, '', ''); >>resetroot.sql Restarted apache and mySQL I still get the same error message.

• Copy large files to multiple machines on a LAN

  - by Jonathan Callen

  I have a few large files that I need to copy from one Linux machine to about 20 other Linux machines, all on the same LAN as quickly as is feasible. What tools/methods would be best for copying these files, noting that this is not going to be a one-time copy. These machines will never be connected to the Internet, and security is not an issue. Update: The reason for my asking this is because (as I understand it) we are currently using scp in serial to copy the files to each of the machines and I have been informed that this is "too slow" and a faster alternative is being sought. According to what I have been told, attempting to parallelize the scp calls simply slows it down further due to hard drive seeks.
