• Hi , is there any wiki that supports ACL , ADI and API ? [closed]

  - by goutham

  Possible Duplicate: Which wiki satisfies ACL ADI and API ? Hi , is there any wiki that supports ACL , ADI and API ? and my requirement is we need a wiki that does three things 1. Uses ACL (Access Control lists - who can access what pages) 2. Needs AD (active directory integration) 3. Is scriptable via an API (meaning I can create a wiki page through an API in a program instead of logging in and manually typing in the page.) Ur help is appreciated Thanks in Advance Goutham

• Windows Server 2012 Essentials - Trying to setup "Anywhere Access" but the "Computer Access" list for users is blank

  - by tetranz

  I have a new installation of Windows Server 2012 Essentials and I'm trying to setup "Anywhere Access" for both VPN and remote desktop. The basic setup is all working. Shared folders is working but remote desktop has no computers available. On the server, if I edit a user with the Essentials Dashboard and go to "Computer access", the list is empty. The desktop computers have been joined to the domain. I can see them in AD under "Computers". I think our mistake was that we didn't use the connector tool to join the domain. We moved from a previous domain and went to Computer / Properties, changed the domain and started with a new profile. Is there something I can do now to make these desktops available for remote desktop? I can access a desktop directly no problem by going directly to it with the RDP client on port 3389. I do that from the outside world through an SSH tunnel.

• How do I Connect a 30yr-old Tandy 1400LT laptop to the internet?

  - by Clemens Bergmann

  Just for the fun of it, I want to get an old Tandy 1400LT laptop: small monochrome display two floppy drives rs-232c connector "printer" connector connect the thing the internet and use it as an ssh terminal. How would I connect it to the internet? The software should be no problem as it is a 386 hardware. There should be a small linux distribution which can be run on it. But how would I phisically connect the hardware? It has no ethernet port. Has someone experience with Serial/Paralel-to-ethernet converters?

• Weighted round robins via TTL - possible?

  - by Joe Hopfgartner

  I currently use DNS round robin for load balancing, which works great. The records look like this (I have a ttl of 120 seconds) ;; ANSWER SECTION: orion.2x.to. 116 IN A 80.237.201.41 orion.2x.to. 116 IN A 87.230.54.12 orion.2x.to. 116 IN A 87.230.100.10 orion.2x.to. 116 IN A 87.230.51.65 I learned that not every ISP / device treats such a response the same way. For example some DNS servers rotate the addresses randomly or always cycle them through. Some just propagate the first entry, others try to determine which is best (regionally near) by looking at the ip address. However if the userbase is big enough (spreads over multiple ISPs etc) it balances pretty well. The discrepancies from highest to lowest loaded server hardly every exceeds 15%. However now I have the problem that I am introducing more servers into the systems, that not all have the same capacities. I currently only have 1gbps servers, but I want to work with 100mbit and also 10gbps servers too. So what I want is I want to introduce a server with 10 GBps with a weight of 100, a 1 gbps server with a weight of 10 and a 100 mbit server with a weight of 1. I used to add servers twice to bring more traffic to them (which worked nice. the bandwidth doubled almost.) But adding a 10gbit server 100 times to DNS is a bit rediculous. So I thought about using the TTL. If I give server A 240 seconds ttl and server B only 120 seconds (which is about about the minimum to use for round robin, as a lot of dns servers set to 120 if a lower ttl is specified.. so i have heard) I think something like this should occour in an ideal scenario: first 120 seconds 50% of requests get server A -> keep it for 240 seconds. 50% of requests get server B -> keep it for 120 seconds second 120 seconds 50% of requests still have server A cached -> keep it for another 120 seconds. 25% of requests get server A -> keep it for 240 seconds 25% of requests get server B -> keep it for 120 seconds third 120 seconds 25% will get server A (from the 50% of Server A that now expired) -> cache 240 sec 25% will get server B (from the 50% of Server A that now expired) -> cache 120 sec 25% will have server A cached for another 120 seconds 12.5% will get server B (from the 25% of server B that now expired) -> cache 120sec 12.5% will get server A (from the 25% of server B that now expired) -> cache 240 sec fourth 120 seconds 25% will have server A cached -> cache for another 120 secs 12.5% will get server A (from the 25% of b that now expired) -> cache 240 secs 12.5% will get server B (from the 25% of b that now expired) -> cache 120 secs 12.5% will get server A (from the 25% of a that now expired) -> cache 240 secs 12.5% will get server B (from the 25% of a that now expired) -> cache 120 secs 6.25% will get server A (from the 12.5% of b that now expired) -> cache 240 secs 6.25% will get server B (from the 12.5% of b that now expired) -> cache 120 secs 12.5% will have server A cached -> cache another 120 secs ... i think i lost something at this point but i think you get the idea.... As you can see this gets pretty complicated to predict and it will for sure not work out like this in practice. But it should definitely have an effect on the distribution! I know that weighted round robin exists and is just controlled by the root server. It just cycles through dns records when responding and returns dns records with a set propability that corresponds to the weighting. My DNS server does not support this, and my requirements are not that precise. If it doesnt weight perfectly its okay, but it should go into the right direction. I think using the TTL field could be a more elegant and easier solution - and it deosnt require a dns server that controls this dynamically, which saves resources - which is in my opinion the whole point of dns load balancing vs hardware load balancers. My question now is... are there any best prectices / methos / rules of thumb to weight round robin distribution using the TTL attribute of DNS records? Edit: The system is a forward proxy server system. The amount of Bandwidth (not requests) exceeds what one single server with ethernet can handle. So I need a balancing solution that distributes the bandwidth to several servers. Are there any alternative methods than using DNS? Of course I can use a load balancer with fibre channel etc, but the costs are rediciulous and it also increases only the width of the bottleneck and does not eliminate it. The only thing i can think of are anycast (is it anycast or multicast?) ip addresses, but I don't have the means to set up such a system.

• How to remove google ads virus from IE?

  - by msbg

  I have picked up adware in that shows extra irrelevant google ads. This only happens in Internet Explorer 10, not Firefox or Iron. I have tried some removals for similar viruses with no luck. I have scanned with MalwareBytes, Windows Defender(I am using Windows 8 RTM, so this is the same as MSE), Spybot, Ad Aware, McAfee, Norton, and AVG, with no luck. Here's a screenshot: As you can see, ads are added to the tan area as well as several extra white results, which are especially irrelevant. I like IE10 and would like to keep using it, but these ads are annoying. I'm also worried there may be spyware as well.

• Use Adblock to allow most ads on a site

  - by jrob

  I leave Adblock turned on for all sites by default. I allow ads on some sites. You can do this by adding an exception for a site that is allowed to show ads. This puts a site in the white list. However, I do not know how to allow most ads on a page, but block a specific ad. I am not even sure Adblock will do this. I believe it is all or none. If a site is in the white list, it appears that all other rules are ignored. Is there a way to allow most ads on a website, but still block specific ads?

• How to unblock chm files - unblock button is missing

  - by Yoav

  I downloaded a CHM file. When I double click it it prompts me to open / save / cancel. Whether I open or save a new copy, the 'new' version will prompt the same open / save / cancel popup ad infinitum. Searching google it seems that Microsoft have deemed it right for security reason to block these files by default. The solution is to right click the file, and click the 'unblock' button at the bottom: The problem is that I don't have that button on my system: BTW, the button is also missing for .exe files.I'm using Win7 64bit. Any ideas?

• OpenLDAP PAM authen does not support SSHA on FreeBSD10

  - by suker200

  OpenLDAP PAM authen does not support SSHA? Hi everyone, Now, I lost one day to figure out, the reason my FreeBSD10 can not authenticate SSH user via LDAP because pam_ldap and nss_ldap do not support SSHA password when OpenLDAP support SSHA method. I have checked /usr/local/etc/ldap.conf, they just have these pam_password methods: clear, crypt, nds, racf, ad, exop. So, If I switch to CRYPT, I can authenticate successfully. So, IMHO, I will be very appreciative for any point or suggestion from everyone to make my FreeBSD10 PAM support SSHA, is there any way or can not? Infor: Ldap Server (389 DS - Centos) - Ldap client (FreeBSD10) what I have got: authen via Ldap between Centos - Centos (Okie). Centos (Ldap Server) - FreeBSD failed (work if I using crypt) Thank and BR Suker200

• How Can I Disable CRL Checks For A Windows 2008 App Using WinHTTP?

  - by Mike B

  I've got a Windows 2008 server with an app that uses WinHTTP for SSL sessions. The server is isolated from the internet but still tries to connect to CRL distribution points, which leads to some timeouts. Since the server has no access to the internet whatsoever, I'd like to disable CRL checks. I had a similar issue on a Windows 2003 server and resolved it by adjusting the following registry keys: HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Http/Parameters/SslBindiongInfo/0.0.0.0:443/DefaultSslCertCheckMode (DWORD=1) HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Rasman/PPP/EAP/13/NoRevocationCheck (DWORD = 1) HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Rasman/PPP/EAP/13/NoRootRevocationCheck (DWORD = 1) That doesn't seem to be working in 2008. I've also tried disabling the CRL check from IE under Tools Internet Options Advanced. Is there anything else I can try here?

• Password expiration notice for Active Directory

  - by keithosu

  Are there any tools/apps/scripts out there that will do password expiry notification for Windows 2008 Active Directory credentials? This is needed for our web apps that use Active Directory for LDAP authentication. The problem is those apps do not notify you that your password is going to expire when you login. We have many offsite users who do not have machines bound to the AD. So there is no way to let them know to reset their password. I'd like the user to be notified 30,7 and 1 day before it expires. I'd also like our help desk to get an email for the expiring passwords for the week and recently expired passwords. I've looked at oldcmp.exe from link text and that gets me my reports but it does not do the automation that I'm looking for on the individual users.

• Toolkit & Habits for Linux Network & System Administration [closed]

  - by slashmais

  I am tasked with the administration of a small office network as well as several workstations running mostly Debian and Ubuntu. There are two servers: one database & print-server, and one backup & file server. Being relatively new to this side of things, knowing enough to help myself to some degree on Linux, I would like to know what software tools and tasks/habits I can use/acquire to learn this field and be effective while doings so. I don't need to know what is the best, just what a newbie sys-admin can use as a starter-pack to learn and use as a base to grow into proper system administration. [edit] What I need is those few basic tools to start with, and the kind of things I need to do regularly, e.g.: which logs to check, when & what to monitor, the kind of 'right' place to start and to which I can ad as I need.

• Send as another user / email address in Exchange 2010

  - by adamo

  In my setup there exist user1, ..., [email protected]. Mail for example.com is handled by Exchange 2010 and all the users user Outlook 2010. There also exists a Standard Distribution list named [email protected]. Is it possible to have some of the users being able to send email with [email protected] as the sender address? Can the sender's GECOS be different too when this happens so that the recipient sees "Offices of Example.com" instead of "User Name X"? Sometimes the secretaries need to send stuff as "the office" and not as theirselves ...

  - by Andrea Polci

  I'm trying to install a linux distribution on my PC. I have a GEForce 8400 GS with two connected monitors. I tried with fedora 12 and ubuntu 9.1 (both 64 and 32 bit) and the live cd cannot boot properly. I don't get a visible error on ubuntu, it simply hang up during the boot. With fedora I get this erro: [drm] Modeset on unsupported output type [drm] Table 0x0000 not found for 1/1 using first I tried to disconnect one of the two monitor and was able to install on my HD and boot from there, but if I try to connect the second monitor again I cannot boot. Have I to install something else? (a driver for my video card for example).

• Setting up a router as a DNS server only

  - by Jacob R

  I have a Linksys WRT54GL router that I don't need anymore, since I had to buy a 3G capable router (Dovado 3GN). As I only have a 3G connection at home, I want to optimize it as much as possible. I want to setup a caching DNS server, including some blacklisting of ad domains. The router currently runs the DD-WRT firmware. Is it possible to use this router as an ordinary computer, running only a DNS server, disabling all other features such as DHCP, WLAN, etc? Connecting it to my other router, should I simply run a cable into the WAN-port of the Linksys router?

• How to find the computer name a user logged on to

  - by V. Romanov

  Hi guys Is there a tool or script or some other way of knowing what computer name a specific user is currently logged on to? Or even was logged on to? Say the user "HRDrone" is working on his machine whose hostname is "HRStation01". I, sitting at my sysadmin desk, only know that the username is "HRDrone". Any way i can find out that he is logged on to "HRStation01" without asking the user? AD event viewer? anything? Thanks!

• Samba4 advice for production use

  - by pgb

  I have an old Samba 3 + LDAP server installed that needs to be rebuilt. I'm weighting my options, and Windows Server seems too expensive at the moment, and Samba 4 appeared to be a nice option, coupled with the last Bind 9 that can dynamically add the computers to the DNS. I have about 30 workstations, so I still consider it a small network. My questions are: Is Samba 4 stable enough for production? It seems as if the Samba team is too cautious on when to call their version final, or even beta, as compared with other open source projects. What Linux distribution would you recommend to set it up? I usually use Ubuntu Server, but may use another one if installing / maintaining Samba 4 is better on that one.

• Exchange 2010 domainprep messing up mailbox permissions on existing Exchange 2003 server

  - by tearman

  So our environment is basically we have an Exchange 2003 server, and we're attempting to move to Exchange 2010 gradually, and move to new hardware while we're at it. So our first step was obviously to get Exchange 2010 installed on the new box. However, after running the domainprep steps listed in http://technet.microsoft.com/en-us/library/bb125224.aspx (including PrepareLegacyExchangePermissions) our mailbox permissions get messed up. Normally, we have an AD security group for Exchange Administrators that allows anyone in that group to view all folders inside any user's mailbox. However, now, this functionality is gone and our Exchange Admins can't access anyone's mailboxes. We'd like to get this functionality back if we could. Thanks

• Apache 2.2 Windows XP Uninstall Doesn't Remove All Files

  - by AJ

  Hello, I am trying to uninstall Apache 2.2 on Windows XP. The original installation was from the binary msi distribution. The uninstall function of the msi ran successfully, but it failed to remove a couple of folders: C:\Apache2.2\conf C:\Apache2.2\logs I am unable to remove these folders manually because they contain files for which I do not have ownership. And this is the source of my confusion: why if I installed the program do I not have permission to remove it? To be clear, I do not have local admin rights (nor can I request them), yet the files in these two remaining folders are owned by Administrator. How is it that Administrator created these files (and how can I possibly remove them)? Thanks, -aj

• SQL 2000 and group names

  - by Nasa

  I have a SQL 2000 server which has databases, under user section of the database object, I have some NT 4.0 groups. These groups were migrated over to Active Directory some time ago using ADMT with SID history. The original source domain groups have since been deleted. The access shown is olddomain\groupname. I don't know why, if they were ntfs permissions they would update automatically to target\groupname. The users in the AD domain still have access to the database as they are a member of the migrated group (Target\groupname). I was wondering 1) Why does the old group (source\groupname) show up as it doesn't exist anymore. But access is still granted to the target group? 2) Is there any easy way to update the group name from source\groupname to target\groupname? Thanks for any help.

• How can I limit CloudFront downloads

  - by Alex Crouzen

  I'm looking to use Amazon's CloudFront to host some content in the near future. Currently, I'm keeping it very simple and I'm just uploading my content to S3 and then making a distribution available via Cloudfront. However, because I have a limited budget, I'd like to be able to limit the number of downloads or the money spent on bandwidth. As far as I can see, I can't set any quotas or budgets like you can in Google's App Engine, so I'm looking for another way of doing this. Has anyone had any experience doing this? One approach I'm thinking of is having to place a webserver with redirects in between, but that kind of defeats the simplicity of CF for me.

• Windows Shares / NTFS permissions on folder redirection in Active Directory

  - by Shawn Gradwell

  A client has folder redirection in AD setup on each user's Home Folder set to the Z:\ drive as \server\share\username. A Group Policy redirects the user's Documents to the user's Home Folder with the option 'Grant the user to exclusive rights to Documents' selected. The share on the server has permissions for the relevant user security group with 'Full Control', but each user's folder only have NTFS permissions only for 'CREATOR OWNER' and 'Domain Admins'. Why can the different users access other user's folders? I thought the most restrictive permissions applied effectively between the share and the NTFS permissions. Also, this setup has been like this for years, and this client recently updated all client computers to Windows 7. What is the best way to setup this redirection now? I assume only in Group Policy, also Basic Redirection - to create a folder for each user under the root path?

• How to refresh open source software pkg manager on oldish OpenSolaris?

  - by Luke404

  I'm being presented with an OpenSolaris vps, actually a Solaris Container, which is based on SXCE snv_121 and is active since mid 2007: the good old Sun days, IIRC even before the Indiana stuff! For various reasons the system itself can't be rebuilt/upgraded but we can do whatever we want with the additional package manager on it. My Solaris skills and especially knowledge of the free package managers ecosystem is a bit rusty so I don't know what I can actually use while keeping the somewhat oldish base system. Currently there is pkg-get using some older Blastwave mirror, it has been used to install things such as Apache2, PHP, Python, Nagios. I would like to remove all the old rusty stuff and all of Blastwave, and start fresh with some newer package distribution. Can the current Blastwave system be used on that snv_121? Is there any better alternative still compatible with that system (eg. OpenCSW or anything else) ?
