• Virtualmin Configuration

  - by Allen

  I am trying to get Virtualmin setup and have reached a point where my noobish sysadmin skills aren't getting the job done. This is the message I get now when I try and refresh the configuration of Virtualmin. BIND DNS server is installed, and the system is configured to use it. However, the default master DNS server XXXXXX is not a fully qualified domain name. Sendmail is only accepting SMTP connections on the following ports : 127.0.0.1 port smtp. Email from other systems on the Internet will not be accepted. This can be changed in the Sendmail Mail Server module. Please advise what I need to do to get Sendmail configured properly. Thanks!

• Add MS-DOS boot option to Windows 2000

  - by Ben Miller

  I've got an old laptop that is running Windows 2000 & Windows 98 in a multi-boot configuration. I need to add MS-DOS to that list of startup options. I've already added a primary partition, formatted it for FAT16 and made it bootable, and installed MS-DOS 6.22. My question is, how do I add my MS-DOS partition to the list of startup options? More information: My single hard drive has three primary partitions: 0: FAT32 Windows 2000 1: FAT32 Windows 98 2: FAT(16) MS-DOS 6.22 Currently, the boot-up screen lists Windows 2000 and Windows 98 as options, with Windows 2000 as the default choice. My boot.ini file currently looks like this: [Boot Loader] Timeout=30 Default=multi(0)disk(0)rdisk(0)partition(1)\WINNT [Operating Systems] multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect C:\="Microsoft Windows 98"

• Process for configuring network settings on a headless rack mount device

  - by PherricOxide

  I'm with a small company that plans to sell a rack mounted network appliance which is configurable via a web interface (think of a router configuration page sort of deal), and I'm wondering in large data center like environments what the process usually is for the initial setup of such systems. The main question is, if the system is headless, how do you get initial remote access to it? Do companies usually first plug a server into a monitor/keyboard/mouse in order to configure the network settings before mounting it in a rack? How else would they know what the IP address of the machine was if DHCP (and it can't be hard coded because of IP conflict potential)?

• Remote Access Problems with DRAC 5 on Dell PowerEdge 1950

  - by Darin Peterson

  Today I received my first Dell PowerEdge 1950 server with a DRAC 5 card. On my local network I have static configurations on my Linux systems using this for instance: iface eth0 inet static address 192.168.1.210 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 dns-nameservers 8.8.8.8 8.8.4.4 For the DRAC card, I configured the LAN like this: address 192.168.1.215 netmask 255.255.255.0 gateway 192.168.1.1 For the advanced LAN settings I used dns-nameservers 8.8.8.8 8.8.4.4 I've tried many different IP addresses, but cannot communicate with the card. Is there anyone who might know if I have configuration issues, or maybe if the card might be bad?

• Mysterious problem...can remotely connect to a system but can't browse back out.

  - by GregH

  I have LogMeIn installed on my home system. I went on travel and my wife called saying that none of our home systems could browse the internet. I thought I would try to connect to my home system using logmein. Surprisingly, I was able to connect to my home system and log in without any problems using logmein. When I opened a browser from my home system, I indeed could not browse. I opened a command prompt and tried to ping my router (192.168.1.1) and it failed/timed out. How is this possible? I can remotely connect to my system but once logged in cannot even ping my router. What's up with that?

• How do I mount a harddrive to my /home folder in OS X?

  - by Joachim Hedberg

  Im wondering how to mount my second HDD to my /home folder like you do in other *NIX systems, making the mount point just that folder and not a standard HDD. I am aware of the method of copying my /home folder and then telling OSX via System Preferences/Users & Groups to look for the folder in a different location. What I am wondering is if there is a way to properly mount the entire HDD to become nothing more than my /home. I don't want it to even show up in Finder as an HDD. Is this even possible?

• Problem with Nobody and PhP

  - by user39190

  We use Cpanel/WHM and have just used EasyApache to upgrade to Apache 2.2 and PhP 5.3.2 As a result of the upgrade process, the user "Nobody" who runs php can no longer access directories or create directories in the various owners web directories. For instance, with Word Press we can no longer upload images. We have tried rebuilding with SuEXEC on and off, SuPHP on and off and nothing makes any difference. It feels as if the user "Nobody" has got its permissions messed up, but that is a wild guess. How can we get back to where we started which is, I assume, that "Nobody" had the rights to the file systems in the web directories?

• Sar data not collected for 10 minutes

  - by Ichorus

  We have a RedHat server whose only job is to run a JBoss server. Monitors said that memory usage spiked (we have the JVM limited to far less than the total memory on the system) and JBoss crashed. We restarted and everything seems ok now. Odd thing is that sar data for 10 min leading up to the crash is simply not there. Load average got up to the 50s. I have seen severely busy systems (350+ Load Average) still collect sar data. Does anyone have any idea what could cause sar to stop collecting data?

• Satellite TV on my PC?

  - by jasondavis

  What would be a good solution for hooking up the satellite TV box (Dish network) in my room to be able to watch it on my PC and possibly record video from it? Please share with me the best cards, cables, software, anything else needed to do this in the most efficient way? I am looking at the WinTV-HVR from Hauppauge. I am not sure, for performance, what would be the best to go with, PCI, PCI express, USB2.0? Also on the Hauppauge website I saw this note: "WinTV-PVR products will not work in PC systems with 4GB or more of memory." The new PC I am building will be 12-24gb of DDR3 RAM, does that mean their products will not work at all with my memory? So confused now!

• Is it possible to create a read-only user account for security auditing purposes?

  - by user2529583

  An organization requires several administrators to have a role of a security auditor. They must have read-only (via network/remote) access to Windows Server 2008 / R2 systems and have permissions to view the server configuration. They must not be able to make any other changes to the server or the network, like restarting or making any configuration chanages. However I can't find any built-in settings for a user like this. The closest thing is the "Users" user group [1], however from my understanding every user in the domain is in this group and cannot view the domain server's configuration. So, what are other options of implementing a read-only user account in Windows Server 2008? [1] http://technet.microsoft.com/en-us/library/cc771990.aspx

• printing foreign text for PHP on UBUNTU and CENTOS

  - by hao

  Hey guys, I am using domdocuments and using things like $div-nodeValue to obtain certain info from a web page. On my ubuntu machine when i do php crawl.php everything is displayed properly in Chinese (the page is in UTF-8). However on my CENTOS machine using the same code I get æ´å¤åå¸ when I print in the terminal. and when I save it to the database, the characters are also messed up. One thing I noticed is that when I do print $content, both systems display them properly.

• Server Room Protocols/Server Room Management

  - by Matthew E

  Hi, I'm new to this site but have found the articles and feedback very useful. We have a Server Room which our Organisation owns and controls, yet there are several thirs party companies that have open access to this room. As such, we have been asked to put together a protocol paper that stipulates the standards that we expect to be adhered to when working in this room. Other than the monitoring of UPS loads, Air Cooling functionality, alarm systems etc, does any one have any guidance on the kind of issues that need to be documented to make this protocol all encompassing? I'm thinking along the lines of not leaving cardboard or other combustibles in the room, not having food and drink in the room, not altering the fabric of the building by drilling through walls etc? Many thanks in advance for any guidance provided.

• Linux server remounted to read-only

  - by Eustahije

  I have tried to find anwser on SF, but no luck. Nothing worked. (and I have just basic knowledge of linux systems - I'm more developer) Hour ago I noticed that database is not reacting anymore. From some reason system went to readonly mode. Complete server is now, ofc, unavailable. Server is VPS in Dutch company, and have no idea what I can do with it now to unlock it. Every suggestion would be more then appriciated. I tried to save as much of database as possible but there are 20G of images, that would be hard to backup, but I can do that also, if that is something that is smart to do.

• Ubuntu issues when moving hard disk to new system

  - by Tim

  I'm working on a legacy project with a small single board computer running Ubuntu 10.04 on a compact flash card. I need to be able to save away a working image (via dd) and copy said image to other compact flash cards for use in other single board computers (with identical hardware) I'm able to copy the image to other flash cards and bootup on other systems no problem. But I'm seeing strange behavior. For instance, I can't use sudo on the new system (“sudo: must be setuid root”). I've gone down the path of trying to fix this, but have run into a slew of other issues. General question is: what do I need to be aware of when moving a hard disk containing Ubuntu (in my case a compact flash card) to another computer? I was hoping it would be seamless to Ubuntu since it's moving to a system with identical hardware. Is there something that needs to be done to make it "portable"?

• Run application or script on Windows RDC connection

  - by NickLarsen

  I checked this thread, but it did not solve my exact problem. I need to run a script on when a connection is made across my network using windows remote desktop connection. The thread listed above works for the initial login, however, if I don't log out (which is necessary for some processes running on my network), then it wont run the script again the next time someone connects to the system using remote desktop connection. Previously we were using pcAnywhere to achieve this, however after running into some graphical issues with pcAnywhere, we have decided to move away from it to RDC. For a little more information, we need to have an email sent out anytime a connection is made to particular machines. The login name will always be the same for those systems and we do not log off when closing the connection.

• HTTPS is not working in transparent proxy with Squid

  - by Supratik

  Hi I am using Squid proxy 3.1, all systems in the LAN connects to the internet through proxy. Direct connection is blocked using the iptables from the gateway server. There are some devices which does not have options for auto proxy or manual proxy and can only connect to the internet directly. So I enabled transparent proxy in Squid and redirected packets for port 80 and 443 to Squid proxy using iptables. Now the problem is it is working fine for HTTP port but HTTPS is not working. It is throwing "ssl_error_rx_record_too_long" error. If it is not possible through transparent proxy can you please suggest me another solution. Warm Regards Supratik

• Access Denied on a Drive where All Users list have been deleted in Security Tab

  - by darkstar13

  Hi All, (System is Windows 7 x64) I wanted to restrict access of other people in a certain drive of my computer (Harddisk 1 is partitioned to C & D; I want to restrict Drive D). What I did was go to the Security Tab (under Drive Properties) and remove the All Users entry. My account is an administrator account. I left only Systems and Administrator on the list. However, when I tried to access drive D, I got an Access Denied error, and Security Tab is already missing. I tried to edit Local Group Policy; it does not work. Take Ownership is not available for the Drive as well, but I see it enabled if I select files / folders. Please help. Thanks. Also, I am wondering why, as an Administrator, have my access to that drive denied.

• Easy Deployment Split Tunnel VPN Connection

  - by Joey Harris

  I was wondering if anybody could offer some insight as to how I can mass deploy VPN connection settings that support split tunneling. It has to work on both Mac and Windows systems though if a script is used, it obviously can be 2 separate scripts for both platforms. I will be setting up a Windows server with a file server and Exchange server and to access the file server I will have the clients go through VPN because we will have sensitive data. I don't want the servers network to be bogged down with the clients normal internet traffic so I will be needing some way to setup split tunneling on the clients without them having to put in a few commands every time to setup the static routes. Ive looked at Cisco VPN client but I want to try and stick with windows RRAS and avoid buying a Cisco VPN endpoint. Im basically looking for a good VPN client that can support split tunneling and mass deployment.

• Difference in VISUAL STUDIO VERSIONS

  - by karthik ram

  I would like to understand some fundamental VS version differences, What is the difference between Visual Studio 2008 and Visual Studio 2008 Team System? Does the Team System 2008 include VS2008, TFS 2008 & Team Explorer 2008? Furthermore, what is the difference betwene Team System 2008 and Team Suite 2008? I beleive there are no more Team Suites or Team Systems in 2010? Does Visual Studio Ultimate 2010 include all Team System components, like TFS 2010 & Team Explorer 2010, so in effect it is like an upgrade of Visual Studio 2008 Team System? Or does TFS 2010 & Team Explorer 2010 need to be installed separately?

• How to install compiler and binutils on FreeNAS?

  - by spoulson

  I'd like to run a backup tool, duplicity, that apparently requires a cc compiler and binutils. I'm able to locate and install the required BSD packages for python, gcc, and dependencies from ftp2.freebsd.org. However, I can't find binutils. How are binutils installed on a system like FreeNAS? I'm working with FreeNAS 0.70 (based on FreeBSD 7.2). I see several packages with binutils in the name, but it's not clear any of them are for my i386 platform. e.g. I see i386-rtems-binutils-2.19.1, but I can't find any info that suggests this is correct for my platform. Google results mention it's for realtime systems.

• XP boot timer=> set, but does nothing?

  - by mark

  My PC has XP Pro and the boot.ini file looks like this: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(2)\windows [operating systems] C:\CMDCONS\BOOTSECT.DAT="Microsoft Windows Recovery Console" /cmdcons multi(0)disk(0)rdisk(0)partition(2)\windows="eXPee Pro" /noexecute=optin /fastdetect Up until about a week ago it would just time-out and boot normally. I haven't made any hardware changes at all. Now, when the system boots it just sits there and waits for me to hit -enter-. I've searched all over for explanations & possible causes, but found nothing which seems to relate. Anyone here have any idea what may have caused the timer to simply quit working like that ? (BTW, the system clock works just as it ever did and keeps time precisely.) Thanks.

• How do you enable syslogd to accept incoming connections on Snow Leopard from remote loggers?

  - by Emmel

  How do I get syslogd to accept incoming connections from remote hosts on Snow Leopard? I'd like to centralize logging such that various devices and systems send logs to Snow Leopard's syslogd, which normally hangs out on UDP 514. However, I'm unable to get them to successfully be accepted by good ole syslogd. I tcpdumped on the Snow Leopard box to verify that packets are being spouted to port 514 -- they are. I checked that syslogd is listening on 514 -- it's not. Googling around told me that, on older versions of OSX (don't you love the way things change so rapidly on OSX), one just had to add a flag to the syslogd daemon to allow remote; one did this in com.apple.syslogd.plist. However the syslogd daemon has no flags (at least in its man page) that suggests any remote anything. What's the solution to this? Secondary, less import but relevant question: What's 'newsyslog'? I see a plist file but it's not running (apparently). Thanks

• Invalid BOOT.INI (dual boot XP with 7)

  - by Muxa

  I had Windows XP x64 as my main system, and i also had a second partition with Windows XP x64. Both booted from first partition (C:) I then installed Windows 7 Ultimate on the first partition. I've added NTLDR using BCDRDIT. I've also copied NTLDR, NTDETECT.COM and BOOT.INI onto the drive where XP remained. However then i try to boot into Windows XP x64 i get Invalid BOOT.INI file Booting from c:\windows\ NTDETECT failed I found instructions on how to fix it using a boot disk, however the partitions are on a software RAID. I've tried to boot from a customized XP CD with the drivers, however it does not offer me a Repair option for some reason - just setup. Partitions that i have:'= System Reserved Main (Windows 7) Secondary (Windows XP x64) Here's the contents of my BOOT.INI: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(3)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(3)\WINDOWS="Windows XP Professional x64 Edition" /fastdetect

• How can I selectively increase latency? E.g. throttle games

  - by Arcymag

  Basically, I want networked games to run poorly on a network, but I want everything else to run smoothly. I would also appreciate advice on blocking games in general. As far as I can tell, there's a few ways to completely prevent an internet game from running: Blocking entirely via DNS configuration (e.g. hosts file), or router DNS configuration Blocking entirely via a separate DNS server Blocking the application, by uninstalling or some kind of access control Blocking the application by automatically killing the process every once in a while Blocking the application by corrupting files periodically However, I would like a more subtle way to block a program. Something that either: Increases latency (would this be doable through some kind of QoS like what DD-WRT offers?) Increases latency by using a special routing configuration for specific target IPs Throttle other systems resources, such as memory, IO, or CPU Screw around with keyboard configurations when a game is launched I would like this to work on MacOSX and Windows, but Linux would be great too. FYI I don't have a kid, but I was brainstorming with some friends and parents.

• Green System Administrator looking for helpful tips

  I have just been promoted to Systems Administrator for our product. We are designing a application that communicates with the cloud(Amazon EC2). I will be in charge of maintaining all Instances and their underlying components. So far this involves a set of load balanced services instances that connect to a central DB in a multi-tennant DB design. Im interested in what other Sys. Admins have discovered as invaluable tools or practices. Any resources provided will be greatly appreciated.
