• How to rename network printer on Windows 7?

  - by Adrian McCarthy

  This question is similar to How do you rename a printer device in Windows 7 64 bit, except the answers there do not work, and I'll provide more information. This is a home network, not a domain. I have set up a Brother HL-5170DN. It is a network printer connected directly to an Ethernet hub. I can connect to it with Windows 7, but on Windows 7 it defaults to the name "binary_p1 on Brn37415f", which isn't very useful. And I cannot seem to change the name. I have it working with several Windows XP and Vista machines, and I can change the name on those machines. On Windows 7 Printer properties: I can see the "binary_p1" name on the General tab. I can select the text, but I cannot change it. The field is not grayed out, but I cannot type anything into it. On the Ports tab, all of the controls are grayed out (disabled). The selected Port is called "\\Brn_37415f\binary_p1", and it's described as "Client Side Rendering Provider" and the printer field says "binary_p1". On the Security tab, I can see that my account has "Manage this printer" permissions. If I choose Printer Server Properties, I can select the port and click Configure Port, but I get a dialog that says, "An error occurred during port configuration. This option is not supported." I have found many forums with people asking the same question without getting an answer. Update: No more bounties to offer, but I'm still looking for a solution to this problem.

• Disabling LDAP Signing on Windows PDC in Local Policy

  - by Golmaal

  I just tripped over my own feet it seems. Playing around on a Windows 2008 R2 server (set up as domain controller), I was intrigued by certain warning event (event id 2886) which says: "To enhance the security of directory servers, you can configure both Active Directory Domain Services (AD DS) and Active Directory Lightweight Directory Services (AD LDS) to require signed Lightweight Directory Access Protocol (LDAP) binds." So I thoughtlessly did some Googling and set the relevant policies which enforce LDAP signing. Now I don't remember but I may have done that using Local Policy. Now I have setup a pfsense box which must authenticate AD users via LDAP. While the firewall can communicate over secure channel, it is difficult to manage the same for other packages such as Squid and SquidGuard. So now I have to disable i.e. undo those policy changes. The problem is that they are greyed out! The policies in question are LDAP server signing and LDAP client signing. I don't remember what I did but when I access these policies from Local Policy editor on the server, they are set to "Require Signing" and are greyed out. The same policies can still be set via Default Domain Controller option in Group Policy editor. So how can I reset these greyed out policies? Thanks

• How to setup firewall to allow internet connection sharing via Wifi USB stick?

  - by hannanaha

  I have a Windows8 computer linked to the internet via an ethernet cable ("Ethernet" network connection). I have attached to it a DLink Wifi USB stick, and I'm trying to share the main PC's internet connection with my Android phone via a local wifi network. I am using the following batch file to set up this network: netsh wlan set hostednetwork mode=allow ssid=MyWifiName key=password keyUsage=persistent netsh wlan start hostednetwork After I run this script, I can see a new network connection appear in "Control Panel\Network and Internet\Network Connections" named "Local Area Connection *12", and I can see "MyWifiName" on the Android phone. The device name for this connection on the PC is "Microsoft Hosted Network Virtual Adapter". I also set up the "Ethernet" connection to share Internet with "Local Area Connection *12". However, the Android phone usually doesn't manage to obtain an IP from the wireless network, and when it does, there still seems to be no connectivity to the internet. When I turn off the Windows Firewall completely, or even just for "Local Area Connection *12", the Android connection is perfect. My questions are: How should I set up the Windows firewall to allow the phone to connect properly? Is there a specific rule I need to add to the Windows firewall advanced settings? [Note: the above method worked great in Windows 7, without any specific tinkering with the firewall]. Is it safe to turn off the firewall specifically for the "Local Area Connection *12" (the wifi connection) if the main Ethernet connection is still protected by the firewall? Thanks in advance.

• Load balancing with puppet

  - by Gonçalo Queirós

  Hi there. Im trying to setup a loadbalancing system. My load balancer (nginx) has a conf file where i should list all IP's of the upstream servers. I could put the IP's on the conf manually, but this ways i would need to change the conf file every time i add/remove an upstream server. For now i came up with two different ideas, but i don't like much of neither: 1 - Have every upstream machine to use Exported Resources to create a file with it's IP..Then the load balancer server will have an "include conf_directory/*", and load all the files created by the upstrem servers. Since the load balancer is using nginx this can be done, but if i wan't latter on to configure something that doesn't have the "include" on the conf files, this solution will not work. 2 - If the config doesn't support the "include" command, then we could have again, every upstream server use the Exported Resources to create a filw with its IP, and latter on, the load balancer execute a command that would pick every file and generate the config Both versions addopt the same techinque, the difference is that version 2 is used when the server (that needs to have a conf generated) doesn't recognize a command like "include" inside its own conf. Now, my question is, is there any way to do this in a different form? I suspect that there is, since puppet is made to manage multiple servers, it seems a bit strange not have a easy way to configure load balancers.

• Deploy our own software using Puppet?

  - by Ken

  (Apologies in advance for the stupidity in this question. I'm normally a programmer, not a sysadmin, but I've taken it upon myself to automate some things, and clean up some other things which are automated but not in the prettiest way. :-) I've been looking around at various tools for automation of software deployment to a bunch of servers, like cfengine, Puppet, and Chef. So far, Puppet looks the most appealing, but I've certainly not committed to anything yet. These tools all look like they can do a great job of keeping a bunch of servers up-to-date with prepackaged software. What I don't get is: how does one use a tool (like Puppet) to manage deployments of our own internal software? I think I'm at a loss because I've seen a thousand tutorials showing how to keep Apache ensure => latest (which is pretty cool), but nothing that quite corresponds to my use-case today, which is something more like: when a human being pushes The Button, pull branch A from the version-control repository B run command C to compile it copy the binaries D to servers E1 through E10 on each server, run command F to make all changes take effect Puppet sounds great, and I totally see the advantage of declarative, idempotent configuration over some shell scripts, but I've not seen any tutorials for "you want to update your shell scripts to Puppet (or Chef, or cfengine) so here's what you should do". Is there such a thing? Is it obvious to other people how to take the things provided in the Puppet docs and replicate the behavior I want? Am I just not getting it? What it's sounding like to me, so far, is that the human being (#1) would manually package the software (#2 and #3) external to Puppet, manually update the Puppet config, which would trigger Puppet to update the servers ... maybe? (I'm a little confused here, as I'm sure you can tell.) Thanks!

• Can a website company that builds 4-5 websites a year afford dedicated hosting?

  - by Petras

  We manage about 30 websites that use shared ASP.NET SQL Server web hosting. These are typical small/medium business websites and they perform fine in this environment. Recently I was looking at VPS hosting in this thread http://serverfault.com/questions/128329/how-do-you-host-multiple-public-facing-websites-on-a-vps After contacting a provider in one of the replies I was told that VPS hosting is not recommended for 30 sites, even if they are small. The resource requirements might be too great even for VPS. So I should turn to dedicated hosting. The lowest cost dedicated hosting is $219 per month (see http://www.serverintellect.com/dedicated/pentiumdservers.aspx). But this is only for a single processor which seems too light for a machine running both IIS and SQL. In our office all the developers work on quad cores so I assume I’d really need the Quad Processor. However, this starts at $599 monthly. Now, I won’t be able to transfer all of our 30 sites to this machine. I’d only be able to transfer say 5 or 6. However, moving forward, I’d be able to host all future sites on this machine. This amounts to 4-5 per year. Let’s look at the economics. Shared hosting costs are typically $16.95 monthly (see http://www.crystaltech.com/dotnet.aspx). So here’s the dilemma First months costs: $599 First month revenue: 6x$16.95 = $101.7 Loss in first month: $497.3 First year costs: $599x12=$7188 First month revenue: 6x$16.95x12 + 5x$16.95x6(averaged) = $1728.9 Loss in first year: $5459.1 Clearly it is going to take years for this server to pay for itself. It just doesn’t seem economical! Am I missing something here, or is dedicated not the way to go with the amount of sites we build?

• VMWare web UI intermittent access on CentOS

  - by PeteWilliams

  I've got a CentOS 5.2 server that I'm trying to get set up as a development environment. As part of this, I planned to install VMWare Server 2 and set up several virtual development servers. I've got as far as installing VMWare Server 2 but access to the remote control panel is only working intermittently. If I access it through Firefox at https://127.0.0.1:8333/ui/# it usually says either: "Connection intterupted: connection was reset before the page loaded" Or "Firefox can't establish a connection to the server at 127.0.0.1" But every now and then it lets me in and I'll manage a few clicks in the web UI before it kicks me out with the following error: "The server could not complete a request (HTTP 0 ). The server encountered an unexpected condition that prevented it from fulfilling the request. If this problem persists, please contact your system administrator." I've done all the updates available in CentOS except one OpenOffice one that is causing a conflict, and I re-ran wmware-config.pl after updating the kernel. Though I went with all the defaults as I don't really know what I'm doing! I've since rebooted and nothing changed. I've also tried accessing the control panel remotely from another machine in the network and the results are the same. Does anyone have any ideas what might be causing this and how I can resolve it? I'm afraid I'm a developer playing at sys-admin, so I may be missing something obvious! Many thanks Pete Update I have now reinstalled both the operating system and VMWare and I'm still getting the same issue. I wonder if it's a result of the settings I'm putting in on the config.pl script..?

• How can I implement ansible with per-host passwords, securely?

  - by supervacuo

  I would like to use ansible to manage a group of existing servers. I have created an ansible_hosts file, and tested successfully (with the -K option) with commands that only target a single host ansible -i ansible_hosts host1 --sudo -K # + commands ... My problem now is that the user passwords on each host are different, but I can't find a way of handling this in Ansible. Using -K, I am only prompted for a single sudo password up-front, which then seems to be tried for all subsequent hosts without prompting: host1 | ... host2 | FAILED => Incorrect sudo password host3 | FAILED => Incorrect sudo password host4 | FAILED => Incorrect sudo password host5 | FAILED => Incorrect sudo password Research so far: a StackOverflow question with one incorrect answer ("use -K") and one response by the author saying "Found out I needed passwordless sudo" the Ansible docs, which say "Use of passwordless sudo makes things easier to automate, but it’s not required." (emphasis mine) this security StackExchange question which takes it as read that NOPASSWD is required article "Scalable and Understandable Provisioning..." which says: "running sudo may require typing a password, which is a sure way of blocking Ansible forever. A simple fix is to run visudo on the target host, and make sure that the user Ansible will use to login does not have to type a password" article "Basic Ansible Playbooks", which says "Ansible could log into the target server as root and avoid the need for sudo, or let the ansible user have sudo without a password, but the thought of doing either makes my spleen threaten to leap up my gullet and block my windpipe, so I don’t" My thoughts exactly, but then how to extend beyond a single server? ansible issue #1227, "Ansible should ask for sudo password for all users in a playbook", which was closed a year ago by mpdehaan with the comment "Haven't seen much demand for this, I think most people are sudoing from only one user account or using keys most of the time." So... how are people using Ansible in situations like these? Setting NOPASSWD in /etc/sudoers, reusing password across hosts or enabling root SSH login all seem rather drastic reductions in security.

• Ubuntu 10.04 bind9 local zone include files and apparmor

  - by Gilgongo

  Rather than putting all my zones in one named.conf.local file, I'd like to have them in groups that I can manage as separate files. So, I've tried putting the following into named.conf.local: include "/home/zones/group1.conf"; include "/home/zones/group2.conf"; include "/home/zones/group3.conf"; However, when I restart named, I see "permission denied" errors in the logs. Ubuntu uses apparmor for bind, so I also added the following in /etc/apparmor.d/usr.sbin.named: /home/zones/group1.conf r, /home/zones/group1.conf r, /home/zones/group1.conf r, Now, when I re-start named, all appears to be well. Zones are loaded (I think). However, a day or two later, I see my secondary name server complaining that the primary is telling it that it's not authoritative for those domains. I then have to put all the domains back into the named.conf.local file again. How can I get bind9 to use include files in this way? I don't know much about apparmor, so that may or may not be the issue here, but I've used include files in this way on Debian OK.

• How to handle files that don't need version control in mercurial

  - by richardh

  I am new to mercurial, and for the most part do LaTeX reports and statistical calculations in R using .csv and/or .sqlite files. Re LaTeX, all I really care is the .tex file. Re R, I don't need version control on the .csv or .sqlite files because they are static. When I do 'hg add' for a repo with a .csv and/or .sqlite file, I get a warning like: rev2.sqlite: up to 3070 MB of RAM may be required to manage this file (use 'hg revert rev2.sqlite' to cancel pending addition) So I revert and subsequently use adds like hg add -X *.sqlite. I guess I really have two questions: (1) Should I ignore these warnings? Because these large files are static, can I just add to the repo knowing that the diff files will always be empty and not worry about wasted resources? (2) If I should keep excluding these files from the repo, is there away that I can fix this option? I.E., add to my .hgrc file something that always appends an option like -I *.tex -I *.R to my 'hg add' commands? Thanks!

• How to get data out of a Maxtor Shared Storage II that fails to boot?

  - by Jonik

  I've got a Maxtor Shared Storage II (RAID1 mode) which has developed some hardware failure, apparently: it fails to boot properly and is unreachable via network. When powering it on, it keeps making clunking/chirping disk noise and then sort of resets itself (with a flash of orange light in the usually-green LEDs); it then repeats this as if stuck in a loop. In fact, even the power button does nothing now – the only way I can affect the device at all is to plug in or pull out the power cord! (To be clear, I've come to regard this piece of garbage (which cost about 460 €) as my worst tech purchase ever. Even before this failure I had encountered many annoyances about the drive: 1) the software to manage it is rather crappy; 2) it is way noisier that what this type of device should be; 3) when your Mac comes out of sleep, Maxtor's "EasyManage" cannot re-mount the drive automatically.) Anyway, the question at hand is how to get my data out of it? As a very concrete first step, is there a way to open this thing without breaking the plastic casing into pieces? It is far from obvious to me how to get beyond this stage; it opens a little from one end but not from the other. If I somehow got the disks out, I could try mounting the disk(s) on one of the Macs or Linux boxes I have available (although I don't know yet if I'd need some adapters for that). (NB: for the purposes of this question, never mind any warranty or replacement issues – that's secondary to recovering the data.)

• Ubuntu xrandr rotate issue

  - by user83544

  I've just bought a second monitor for my PC which happens to be a pivot monitor. I've already read lots of forums related to my problem but haven't come across a solution - I have the same symptoms as dozens of posts but no matter whatever I try it just doesn't work. I've already changed the xorg.conf file and added in the device section just under Driver "nvidia" the following for my second monitor: Option "RandRRotation" "on" When I save and reboot I try to rotate my screen with the nvidia X server settings by choosing the second monitor and clicking either "left" or "right" for the rotation. It immediately exits the nvidia settings window and does nothing. I tried within the terminal by typing: xrandr -o right I get the following error: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 154 (RANDR) Minor opcode of failed request: 2 (RRSetScreenConfig) Serial number of failed request: 14 Current serial number in output stream: 14 I actually manage to rotate it with Option "Rotate" "CCW" instead of "RandRRotation". The problem with this solution is that you get the second monitor in the right position, but any window you open on that screen is practically unchangeable. You can't change the size nor move it, making it useless for reading PDFs, which is the main reason why I bought this second screen to help me write my thesis. Any help is really appreciated. sudo lshw -c video hiram@hiram-linux:~$ sudo lshw -c video *-display description: VGA compatible controller product: nVidia Corporation vendor: nVidia Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:16 memory:f8000000-f9ffffff memory:d8000000-dfffffff memory:d4000000-d7ffffff ioport:dc00(size=12 memory:fbd80000-fbdfffff

• [tcpdump] Proxy delegate refusing connexion ?

  - by simtris

  Hi guys, I'm a little disapointed ! My aim was to build a VERY simple smtp proxy under debian to handle mail from a port (51234) and forward it to the standard 25 port. I compile and install a "delegate" witch can handle easily that. It's working very well like that : delegated SERVER="smtp://anotherSmtpServer:25" -P51234 The strange thing is, it's working on my virtual test machine and on the dedicated server in local but I can't manage to use it trought internet. I test it like that. telnet [mySrv] 51234 Of course, no firewal, no deny host, no ined/xined, the service delegated is listening on the right port ... 2 clues : The port is answering trought internet with nmap as "51234/tcp open tcpwrapped" have a look at the tcpdump following : 22:50:54.864398 IP [myIp].1699 [mySrv].51234: S 2486749330:2486749330(0) win 65535 22:50:54.864449 IP [mySrv].51234 [myIp].1699: S 2486963525:2486963525(0) ack 2486749331 win 5840 22:50:54.948169 IP [myIp].1699 [mySrv].51234: . ack 1 win 64240 22:50:54.965134 IP [mySrv].43554 [myIp].auth: S 2485396968:2485396968(0) win 5840 22:50:55.243128 IP [myIp] [mySrv]: ICMP [myIp] tcp port auth unreachable, length 68 22:50:55.249646 IP [mySrv].51234 [myIp].1699: F 1:1(0) ack 1 win 46 22:50:55.309853 IP [myIp].1699 [mySrv].51234: . ack 2 win 64240 22:50:55.310126 IP [myIp].1699 [mySrv].51234: F 1:1(0) ack 2 win 64240 22:50:55.310137 IP [mySrv].51234 [myIp].1699: . ack 2 win 46 The part "auth" seems suspect to me but didn't ring a bell.

• How can I install iTunes in such a way that it can't put any "hooks" or helper programs on my computer?

  - by Joshua Carmody

  I'm buying a new iPad, which means I must once again install iTunes. I've not used iTunes in more than 6 months, since I bought a new computer. I don't like iTunes, but I can live with using it to buy/manage media and sync my Apple devices when the program is open. What I would like to do though, is find a way to install iTunes in such a way that it has absolutely no effect on my system when it is closed. iTunes normally installs several helper programs such as iTunesHelper.exe, and the Bonjour service. These programs run in the background when iTunes is closed. You can force-close them, or remove them from your setup files, but iTunes will often put them right back when you run it. I know these programs are mostly harmless, but they have at times caused issues such as iTunes spending system resources trying to catalog media files or drives connected to VPN, or other issues. At best they're just one more small background process eating up a small piece of my CPU time and RAM. How can I run iTunes without letting it get it's "hooks" into my system? One thought I had is that I could create a Windows user account just for iTunes, and deny it admin privileges. Then if I installed iTunes using that account maybe anything it installed wouldn't affect the "main" account on my PC? But I'm not sure if that would work.... Failing that, maybe some kind of virtualization software or sandbox I could install it in? I'm open to any suggestions. My system is an Intel-based PC running Windows 7 Professional 64-bit. Thanks!

• Systemd Service Start With Dynamic Port Value From Docker

  - by Sheriffen

  Using CoreOS, Docker and systemd to manage my services I want to properly perform service discovery. Since CoreOS utilizes etcd (distributed key-value) there is a very convenient way to do this. On systemd's ExecStartPost I can just insert the started service into etcd without problems. My usecase needs something like this: ExecStartPost=/usr/bin/etcdctl set /services/myServiceName '{ \"host\": \"%H\", \"port\": 5555 }' which works like a charm. But this is where my idea popped up. Docker has the power to randomly assign a port if I just run docker run -p 5555 which is awesome since I don't have to set it statically in the *.service file and I could possibly run multiple instances on the same host. What if I could get the randomly assigned port and insert instead of the static 5555? Turns out I can use the docker port command to get the port and with some formatting we can get just the port with $(echo $(/usr/bin/docker port my-container-name 5555) | cut -d':' -f2) which works if I set it (using bash) like this: /usr/bin/etcdctl set /services/myServiceName '{ \"host\": \"%H\", \"port\": '$(echo $(/usr/bin/docker port my-container-name 5555) | cut -d':' -f2)' }' but using systemd I just can't get it to work. This is the code I'm using: ExecStartPost=/usr/bin/etcdctl set /services/myServiceName '{ \"host\": \"%H\", \"port\": '$(echo $(/usr/bin/docker port my-container-name 5555) | cut -d':' -f2)'}' Somehow I got something wrong but it's hard to debug since it works when typed in the terminal.

• Apache httpd: Send error logs to syslog and local disk? Without touching /etc/syslog.conf?

  - by Stefan Lasiewski

  I have an Apache httpd 2.2 server. I want to log all messages using syslog, so that the requests are sent to our central syslog server. I also want to ensure that all log messages are sent to local disk, so that a sysadmin can have easy access to the log files on the local system. It is easy to send HTTP access logs to both the local disk and to syslog. One common method is: LogFormat "%V %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined CustomLog logs/access_log combined CustomLog "|/usr/bin/logger -t httpd -i -p local4.info" combined But it is not easy to do this for error logs. The following configuration doesn't work, because the error logs only use the last ErrorLog stanza. The first ErrorLog stanza is ignored. ErrorLog logs/error_log ErrorLog syslog:local4.error How can I ensure that Apache errors logs are written to the local disk and are sent to syslog? Is it possible to do this without touching /etc/syslog.conf ? I am fine if my users want to manage their own Apache configuration files, but I do not want them touching system files such as /etc/syslog.conf

• "could not find suitable fingerprints matched to available hardware" error

  I have a thinkpad t61 with a UPEK fingerprint reader. I'm running ubuntu 9.10, with fprint installed. Everything works fine (I am able to swipe my fingerprint to authenticate any permission dialogues or "sudo" prompts successfully) except for actually logging onto my laptop when I boot up or end my session.

• Site Goes Offline Every Day At Midnight - No One Knows Why

  - by HollerTrain

  0 down vote favorite Seems today a website I manage has been going online and offline between 12a and 12:25a. I have no idea what is causing the issue so I am seeking guidance on where to start. It is a Wordpress based site. So here is what I DO know: I have a pingdom account which alerts me when the site goes offline so we can see every day, like clockwork, the site goes on/off. At the time of the ups/downs I see a lot of strain on the memory usage. Look at the load average when the site is going online/offline (http://screencast.com/t/BRlfXkqrbJII). Then I ran this command to restart http (http://screencast.com/t/usVtYWZ2Qi) and the memory usage then goes down to this (http://screencast.com/t/VdTIy3bgZiQB). An hour after I restarted http, the site then went offline/online so restarting the http didn't do much help. When the site is going offline/online, I ran the top command and get this (http://screencast.com/t/zEwr7YQj3). Here is a top command when the site is at it's lowest (http://screencast.com/t/eaMfha9lbT - so this would be dubbged "normal"). Here is a bandwidth report (http://screencast.com/t/AS0h2CH1Gypq). The traffic doesn't seem to be that much (http://screencast.com/t/s7hrWNNic1K), but looking at my times the site is going up/down this may be one of the reasons? I have the dvp Nitro package at Media Temple (http://mediatemple.net/webhosting/nitro/). So at this point I would request some help in trying to figure out what the cause of this is, and how I can go about pinpointing this issue. ANY HELP is greatly appreciated.

• How to implement a virtual server running Ubuntu inside a fileserver in windows?

  - by user541445

  I work in a company that has some limitations regarding their budget. They need client/server aplication. I can code the aplication, I've made mini tests on primordial applications that work. The thing is that they only have fileservers, and the application they need must be concurrent compliant, so the database must be in their local network (Fileserver is the only choice). So far, I have explored almost any option available, starting with: Desktop databases. Access (We have a license)(But concurreny is just not effective, besides it's a windows software, yuck). Sqlite (Nice, but since the information they manage is a lot, I've performed some concurrency tests with INSERTs and doing SELECTS at the same time). It fails, somehow it just stops inserting. Open office Base (I dismember a base office only to see that it was a file mode HSQLDB). I've tried, not concurrent at all. Etc (You name the Open source Desktop Database manager, and yes, I've tried that one.) Server databases Call me a stubborn person, but reading some server databases documentation say that their databases will work in a file mode. I've tried a lot of products. Postgres, MySQL, FireBird, H2, Derby, Oracle Express, IBM DB2 Express, etc. So, I really need a hand here, I've been doing this install/delete/depression thing with a lot of databases for 3 weeks, until I got with a crazy idea and I just came here to express it. So, my question comes down to this: Installing a light virtual OS software like Virtual PC and then installing in there a Server OS like an Ubuntu server inside that virtual software will work? Will it work 24/7 or when I close the virtual pc software? Will this work in a fileserver? Any suggestion, answer, critic to the place I work, crazy new concurrent database that will work in fileserver will be most than welcome.

• Users and Groups management on 7 Home Premium

  - by AviD

  Recently upgraded the home pc from XP pro, to Windows 7 Home Premium. I'm looking for a solution for a few things that seem to be missing from this edition... Since Local Users and Groups is blocked on Home Premium, I can't figure out how to manage groups, or even do anything even slightly advanced to users (basically, create/group/picture is it). net localgroup, net users, net etc dont seem to work - getting "system error 5". While I'm on the topic, I cant activate (what was once) "Local Security Policy"... Looking for any help, advice, or even a new direction cuz things is differ'nt on Winnows7... To clarify, I'm looking to do some of the following, which were simply back in XP-land: remote user only (i.e. no local logon) Grant special privileges for specific user grant access to e.g. C$ share for specific remote user create custom groups for users, to be able to separate privileges of say, my wife's from my kids define quite specifically what each user can do (beyond just standard users) Harden OS (hmm, i guess maybe what i'm looking for is security hardening guide for 7...?)

• VMWare web UI intermittent access on CentOS

  - by PeteWilliams

  Hiya, I've got a CentOS 5.2 server that I'm trying to get set up as a development environment. As part of this, I planned to install VMWare Server 2 and set up several virtual development servers. I've got as far as installing VMWare Server 2 but access to the remote control panel is only working intermittently. If I access it through Firefox at https://127.0.0.1:8333/ui/# it usually says either: "Connection intterupted: connection was reset before the page loaded" Or "Firefox can't establish a connection to the server at 127.0.0.1" But every now and then it lets me in and I'll manage a few clicks in the web UI before it kicks me out with the following error: "The server could not complete a request (HTTP 0 ). The server encountered an unexpected condition that prevented it from fulfilling the request. If this problem persists, please contact your system administrator." I've done all the updates available in CentOS except one OpenOffice one that is causing a conflict, and I re-ran wmware-config.pl after updating the kernel. Though I went with all the defaults as I don't really know what I'm doing! I've since rebooted and nothing changed. I've also tried accessing the control panel remotely from another machine in the network and the results are the same. Does anyone have any ideas what might be causing this and how I can resolve it? I'm afraid I'm a developer playing at sys-admin, so I may be missing something obvious! Many thanks Pete Update I have now reinstalled both the operating system and VMWare and I'm still getting the same issue. I wonder if it's a result of the settings I'm putting in on the config.pl script..?

• HTC Diamond Touch sync problem

  - by Anders

  I have a HTC Diamond Touch with all my contacts etc. on it. Did however not use it for 6mo while being abroad. When I start the phone now I realize that the touch screen has stopped working. I have tried restarting, soft resetting, shutting it off etc but the touch just wont follow commands. However, I can manage the phone by buttons so it's not frozen. Hence I can get into the phone and watch contacts but not use it to call etc. The problem is, how do I get my 300 contacts out of the thing!? When I'm plugging in the phone, it lets me choose between "Sync with Outlook" and "Use as storage device". It automatically selects "Use as storage device". Now, I cannot choose to sync it with the buttons. I can not change this option afterwards either. In short, I have a phone with all of my contact data and am completely unable to get that out of it. Any tips/help/suggestions? If possible, preferably one that does not including sending the phone to a hardware workshop for three weeks in order to get it fixed:)

• Synchronize Active Directory to Database

  - by Tommy Jakobsen

  We are in a situation where we would like to offer our customers to be able to manage their users themselves. It is around 300 customers with up to a total of 10.000 users. Besides creating, updating and removing users, they will very often read information about users for statics and other useful informations available. All this functionality, should be available from an Intranet web page (.NET Framework 4) that the users will access through Citrix or similar. Now the problem is that we would really like the users not to query AD directly for each request, but rather make them hit a database that is synchronized with AD. It would be sufficient to run this synchronization a few time each day (maybe every 5. hour). When they create a user, it should not be available right away, but reviewed and then created within two days (the next step would be to remove this manual review, but that's out of scope for this question). What do you think about this synchronization of AD? Does anyone have any experience with it and is it something that is done in other organizations, where you will have lots of requests which is better handled by a database than AD (I presume)? Are there any techniques out there for writing such a script that synchronizes AD with database tables? My primary concern is the groups/members relations which can be rather complicated. Or are there software that synchronizes AD with a database? Any comments will be much appreciated. Thank you.

• Windows 7 Blank Screen on Boot / Login

  - by Greg

  I have a new system that's having a few problems... sometimes (seems to be when the PC is cold, i.e. has been switched off for a while, though that could be my imagination) I get a blank blue screen when I boot up. The system boots normally and auto-logs-in. The desktop loads and I'm even able to launch applications, but then everything disappears and the screen goes to the default windows desktop blue colour (not the desktop image, just a plain blue with no mouse cursor). At this point the machine completely locks up - I'm unable to even toggle Num Lock and have to hold in the power button for 5 seconds to kill it. Interestingly if I manage to launch some applications before it goes blank, they will usually crash... sometimes explorer.exe will crash too. When I reboot, the system is fine and stable. I've installed the latest graphics drivers and run memtest86+ for 6 passes (and counting) with no errors. The system specs are: CPU: Intel I7 2.66 @ 3.4GHz RAM: 6GB (3 * 2GB DDR3) HDD: 128GB Crucial M225 SSD Motherboard: Gigabyte EX58-UD3R Gfx: ATI Radeon Sapphire 5870 1GB Note: There are a few similar questions but I haven't found one that matches my symptoms

• Cisco ASA user authentication options - OpenID, public RSA sig, others?

  - by Ryan

  My organization has a Cisco ASA 5510 which I have made act as a firewall/gateway for one of our offices. Most resources a remote user would come looking for exist inside. I've implemented the usual deal - basic inside networks with outbound NAT, one primary outside interface with some secondary public IPs in the PAT pool for public-facing services, a couple site-to-site IPSec links to other branches, etc. - and I'm working now on VPN. I have the WebVPN (clientless SSL VPN) working and even traversing the site-to-site links. At the moment I'm leaving a legacy OpenVPN AS in place for thick client VPN. What I would like to do is standardize on an authentication method for all VPN then switch to the Cisco's IPSec thick VPN server. I'm trying to figure out what's really possible for authentication for these VPN users (thick client and clientless). My organization uses Google Apps and we already use dotnetopenauth to authenticate users for a couple internal services. I'd like to be able to do the same thing for thin and thick VPN. Alternatively a signature-based solution using RSA public keypairs (ssh-keygen type) would be useful to identify user@hardware. I'm trying to get away from legacy username/password auth especially if it's internal to the Cisco (just another password set to manage and for users to forget). I know I can map against an existing LDAP server but we have LDAP accounts created for only about 10% of the user base (mostly developers for Linux shell access). I guess what I'm looking for is a piece of middleware which appears to the Cisco as an LDAP server but will interface with the user's existing OpenID identity. Nothing I've seen in the Cisco suggests it can do this natively. But RSA public keys would be a runner-up, and much much better than standalone or even LDAP auth. What's really practical here?
