• Motorola SBG6850 / Linksys WRT54G network problem

  - by user96407

  I am trying to resolve issues with connecting my desktop and LAN capable printer to my network. I recently upgrade to the Motorola Cable Modem Gateway SBG6580 and have TWC coming into it, this works great for wired and wireless connectivity. Although, I am unable to connect to my device from this modem gateway. So, I am trying to cable a Linksys WRT54G (firmware 4.21.4 build 0) to the backside of the SBG6850 so I can use my printer on my network from both my wired desktop and wireless devices. I am pulling wireless off of the SBG6580 and do not want to change this. I have disable the wireless feature on the Linksys WRT54G at this moment. Can someone please help me through this dilemma? I am open to both wired and wireless solutions, but please tell me which approach your sharing in the first line of your response. Cheers!

• Plugging GlusterFS and Openfiler together

  - by lpfavreau

  Has anyone had experience plugging GlusterFS and Openfiler together or something similar? Here is the motivation: Disk space on multiple server regrouped using GlusterFS Centralized access using LDAP/AD and quota management using Openfiler as the GlusterFS client SMB/CIFS server for easy sharing to multiple users on Mac and Windows I know I can have Gluster installed on Openfiler (rPath Linux) successfully but Openfiler seems to be very picky on what it can use as a shared drive. Mounting the Gluster volume inside an existing share does not seem to allow quotas with the mounted folder free space. If this is not possible, is there any alternative to give the same capabilities?

• Virtual PC, XP mode. Bidirectional parallel port physical LPT1 not available in VPC XP mode?

  - by Tom Merklin

  I need my LPT1 port to be available in XP mode. In the "guest" window, it shows up in system hardware, but it is not available to the application. If I look into Tools, settings there are no parallel port available? How can I fix this problem? (If I use VMWare Workstation XP mode, I load a driver and it works perfect).

• DHCP server with multiple interfaces on ubuntu, destroys default gateway

  - by Henrik Kjus Alstad

  I use Ubuntu, and I have many interfaces. eth0, which is my internet connection, and it gets its info from a DHCP-server totally outisde of my control. I then have eth1,eth2,eth3 and eth4 which I have created a DHCP-server for.(ISC DHCP-Server) It seems to work, and I even get an IP-address from the foreign DHCP-server on the internet facing interface. However, for some reason it seems my gateway for eth0 became screwed after I installed my local DHCP-server for eth1-eth4. (I think so because I got an IP for eth0, and I can ping other stuff on the local network, but I cannot get access to the internet). My eth0-specific info in /etc/network/interfaces: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 inet static address 10.0.1.1 netmask 255.255.255.0 network 10.0.1.0 broadcast 10.0.1.255 gateway 10.0.1.1 mtu 8192 auto eth2 iface eth2 inet static address 10.0.2.1 netmask 255.255.255.0 network 10.0.2.0 broadcast 10.0.2.255 gateway 10.0.2.1 mtu 8192 My /etc/default/isc-dhcp-server: INTERFACES="eth1 eth2 eth3 eth4" So why does my local DHCP-server fuck up the gateway for eth0, when I tell it not to listen to eth0? Anyone see the problem or what I can do to fix it? The problem seems indeed to be the gateways. "netstat -nr" gives: 0.0.0.0 --- 10.X.X.X ---- 0.0.0.0 --- UG 0 0 0 eth3 It should have been 0.0.0.0 129.2XX.X.X 0.0.0.0 UG 0 0 0 eth0 So for some reason, my local DHCP-server overrides the gateway I get from the network DHCP. Edit: dhcp.conf looks like this(I included info only for eth1 subnet): ddns-update-style none; not authoritative; subnet 10.0.1.0 netmask 255.255.255.0 { interface eth1; option domain-name "example.org"; option domain-name-servers ns1.example.org, ns2.example.org; default-lease-time 600; max-lease-time 7200; range 10.0.1.10 10.0.1.100; host camera1_1 { hardware ethernet 00:30:53:11:24:6E; fixed-address 10.0.1.10; } host camera2_1 { hardware ethernet 00:30:53:10:16:70; fixed-address 10.0.1.11; } } Also, it seems that the gateway is correctly set if I run "/etc/init.d/networking restart" in a terminal, but that's not helpful for me, I need the correct gateway to be set during startup, and i'd rather find the source of the problem

• Listing side projects in a jr. sysadmin resume

  - by Beaming Mel-Bin

  I have many "side-projects" that were not part of my past jobs. Just for example: Configuring web site environment for professors and friends Configuring a Linux box that does the routing, firewall (iptables), backup and file sharing (samba) for my apartment Developing small websites for things as simple as party invites to polling friends. Running my own SMTP server with domain keys, SPF and DNSBL Etc., etc. What would be the appropriate section to mention this? Should I even mention it? Perhaps it's best to just bring it up during the interview. I would especially appreciate the opinion of hiring managers.

• Where can I buy a good rackmount workstation?

  - by yan bellavance

  We have a product which consists of a GUI program and all the hardware goes in a rack. Our department bought a rackmount server for the first unit, but I dont think this is adequate for applications that use graphics (correct me if I'm wrong - we bought a Dell R710). Could you tell me of a good rackmount workstation we could buy for our product? Also, would it be risky for us to build our own rackmount?

• Common and maximum number of virtual machines per server?

  - by Rabarberski

  For a project I am trying to get real-life estimates for the number of virtual machines per server, both typically and maximally. Of course, the maximum number of VMs would be depending on the type of applications (disk intensive, network intensive, ...), and server hardware (like number of cores, memory, ...), but still it would be useful to know if a typical maximum is about 10, 20 or 30 VMs per server. Can anybody give practical numbers?

• Coding exercise for Linux Systems Admin?

  - by Prashanth Sundaram

  Hello All, I am preparing for a Systems Admin(linux) role for a big company(top 10 companies) and one of the requisite is knowledge of a language like perl, python or Ruby. I have a phone interview which involves sharing a editor with the interviewer, now what kind of coding exercise can I expect on a phone interview or a regular interview? I have used shell for most of my day-to-day tasks and occasionally Perl and python for bigger tasks. Now I don't expect them to ask Write a script that sync's AD users to LDAP? I don't think data structures, algorithms or sorting questions apply to me role? Can you give me any examples of SysAdmin related coding questions?

• Windows 7 Machine Makes Router Drop -All- Wireless Connections [closed]

  - by Hammer Bro.

  Note: I accidentally originally posted this question over at SuperUser, and I still think the issue is caused by some low-level networking practice of Windows 7, but I think the expertise here would be more apt to figuring it out. Apologies for the cross-post. Some background: My home network consists of my Desktop, a two-month old Windows 7 (x64) machine which is online most frequently (N-spec), as well as three other Windows XP laptops (all G) that only connect every now and then (one for work, one for Netflix, and the other for infrequent regular laptop uses). I used to have a Belkin F5D8236-4 wireless router, and everything worked great. A week ago, however, I found out that the Belkin absolutely in no way would establish a VPN connection, something that has become important for work. So I bought a Netgear WNR3500v2/U/L. The wireless was acting a little sketchy at first for just the Windows 7 machine, but I thought it had something to do with 802.11N and I was in a hurry so I just fished up an ethernet cable and disabled the computer's wireless. It has now become apparent, though, that whenever the Windows 7 machine is connected to the router, all wireless connections become unstable. I was using my work laptop for a solid six hours today with no trouble, having multiple SSH connections open over VPN and streaming internet radio in the background. Then, within two minutes of turning on this Windows 7 box, I had lost all connectivity over the wireless. And I was two feet away from the router. The same sort of thing happens on all of the other laptops -- Netflix can be playing stuff all weekend, but if I come up here and do things on this (W7) computer, the streaming will be dead within ten minutes. So here are my basic observations: If the Windows 7 machine is off, then all connections will have a Signal Strength of Very Good or Excellent and a Speed of 48-54 Mbps for an indefinite amount of time. Shortly after the Windows 7 machine is turned on, all wireless connections will experience a consistent decline in Speed down to 1.0 Mbps, eventually losing their connection entirely. These machines will continue to maintain 70% signal strength, as observed by themselves and router. Once dropped, a wireless connection will have difficulty reconnecting. And, if a connection manages to become established, it will quickly drop off again. The Windows 7 machine itself will continue to function just fine if it's using a wired connection, although it will experience these same issues over the wireless. All of the drivers and firmwares are up to date, and this happened both with the stock Netgear firmware as well as the (current) DD-WRT. What I've tried: Making sure each computer is being assigned a distinct IP. (They are.) Disabling UPnP and Stateful Packet Inspection on the router. Disabling Network Sharing, SSDP Discovery, TCP/IP NetBios Helper and Computer Browser services on the Windows 7 machine. Disabling QoS Packet Scheduler, IPv6, and Link Layer Topology Discovery options on my ethernet controller (leaving only Client for Microsoft Networks, File and Printer Sharing, and IPv4 enabled). What I think: It seems awfully similar to the problems discussed in detail at http://social.msdn.microsoft.com/Forums/en/wsk/thread/1064e397-9d9b-4ae2-bc8e-c8798e591915 (which was both the most relevant and concrete information I could dig up on the internet). I still think that something the Windows 7 IP stack (or just Operating System itself) is doing is giving the router fits. However, I could be wrong, because I have two key differences. One is that most instances of this problem are reported as the entire router dying or restarting, and mine still works just fine over the wired connection. The other is that it's a new router, tested with both the factory firmware and the (I assume) well-maintained DD-WRT project. Even if Windows 7 is still secretly sending IPv6 packets or the TCP Window Scaling implementation that I hear Vista caused some trouble with (even though I've tried my best to disable anything fancy), this router should support those functions. I don't want to get a new or a replacement router unless someone can convince me that this is a defective unit. But the problem seems too specific and predictable by my instincts to be a hardware hiccup. And I don't want to deal with the inevitable problems that always seem to take half a day to resolve when getting a new router, since I'm frantically working (including tomorrow) to complete a project by next week's deadline. Plus, I think in the worst case scenario, I could keep this router connected directly to the modem, disable its wireless entirely, and connect the old Belkin to it directly. That should allow me to still use VPN (although I'll have to plug my work laptop directly into that router), and then maintain wireless connections for all of the other computers. But that feels so wrong to me. Anyone have any ideas what the cause and possible solution could be? Clarifications: The Windows 7 machine is directly connected via an ethernet cable to the router for everything above. But while it is online, all other computers' wireless connections become unusable. It is not an issue of signal strength or interference -- no other devices within scanning range are using Channel 1, and the problem will affect computers that are literally feet away from the router with 95% signal strength.

• Bare-Metal Restores of Linux Servers with Tivoli

  We currently use IBM Tivoli to back up our Linux servers and we are looking for suggestions on the best way to restore to bare metal. I've read IBM's doc on this issue. Is that still relevant or is there a better way? Also, how do you handle testing a restore to a vm or another piece of hardware on the same network that the original server lives?

• Windows shared printers: Process job on server machine, not the client

  - by asr

  Hi. While working with Linux clients to Windows SMB/CIFS filesharing servers, from time to time I find myself having to print to a printer with no drivers available under Linux. For some reason, the Windows computer expects the job to be sent in an already processed format, so it can be fed directly to the printer in its own, weird language. It would be great if I could send the print job in Postscript or other standard format to the Windows computer sharing this printer, and then this PS could be processed under Windows. Is there a way to accomplish this? Because I don't seem to find the option. Thanks a lot.

• Run one virtual machine on a Linux server + standard Linux functions

  - by fistameeny

  Hi, I am looking for a method to setup a Linux server (running Ubuntu Server) that uses Samba for file sharing, as well as hosting a Windows virtual machine (in this case, Windows Small Business Server 2003, which in turn hosts SQL Server Express - Exchange won't be used on this). I would like to have the Linux server serving the files over Samba, and hosting the Virtual Machine. This obviously rules ESXi out as it couldn't do Samba at the same time. What would be the next best solution to give reasonable speed? Vmware Server 2.0, VirtualBox, Xen? There will be 10-15 users accessing the Samba shares and the SQL Express virtual machine. Matt

• Mac OS X: pushing all traffic through a VMWare VM [closed]

  - by bj99

  I want to set up an Astaro (Sophos) UTM in a Virtual Machine. The Setup should be at the end the following: Cable Modem (one IP adress) | [Ethernet] Sophos UTM (running as VM [VMWare Fusion 5] on the MacMini) | [WIFI] Airport Express v2 (for sharing Local Network to wireless and wired clients) 1)| [WIFI] 2)| [Ethernet over Thunderbolt Ethernet Adapter]* Clients MacMini (Local File Server) *To have the Mini also protected behind the UTM So the setup process for the UTM works fine, but then the problems start: I just have one external IP (from my cable modem provider)== So if I put the VM in briged mode my Internet connection drops, because the MacMini also has its IP adress. If I put the VM to NAT mode the Mini itself is not protected by the UTM So: is there a way to hide the en0 interface(Ethernet) and the en1 interface (Wifi) from the MacMini, so that they not even appear in System Preferences Network section but are available to the VM? That way the Mini must connect to the en2 interface (Thunderbolt adapter) to make any Internet/LAN connection and I just use the given single IP from the Cable Modem. Thaks for any suggestions...

• VPN Connects with local access only

  - by user20102

  I have Windows Server 2008 and I have set up a VPN. When a user logs into their VPN they can not view the internet. It comes up as local access only on the the client PC. On the server when I go to the Network And Sharing Centre it displays (Network) with local and internet below it has the RAS Dial-in interface and it displays as local only there as well. I want all users that connect to my VPN to have internet access (full access). If anyone can help me it would be appreciated. Also I've activated dial-in properties and I've done it via policy who can access the VPN and internet. It still doesn't work, but there is a connection but just local only. Thanks

• How to make Linux reliably boot on multi-cpu machines?

  - by Adam Tabi

  I've got two machines, one with 4x12 AMD Opteron cores (AMD Opteron(tm) Processor 6176), one with 2x8 Xeon cores (HT disabled; Intel(R) Xeon(R) CPU E5-2660 0 @ 2.20GHz). On both machines I experience difficulties during boot of Linux using recent kernels. The system hangs during the initialization of the kernel, before or just when initramfs started initializing the hardware. The last thing which got displayed was a stacktrace like this: CPU: 31 PID: 0 Comm: swapper/31 Tainted: G D 3.11.6-hardened #11 Hardware name: Supermicro X9DRT-HF+/X9DRT-HF+, BIOS 3.00 07/08/2013 task: ffff880854695500 ti: ffff880854695a28 task.ti: ffff880854695a28 RIP: 0010:[<ffffffff8100a82e>] [<ffffffff8100a82e>] default_idle+0x6/0xe RSP: 0000:ffff8808546b3ec8 EFLAGS: 00000286 RAX: ffffffff8100a828 RBX: ffff880854695a28 RCX: 00000000ffffffff RDX: 0100000000000000 RSI: 0000000000000000 RDI: ffff88107fdec690 RBP: ffff8808546b3ec8 R08: 0000000000000000 R09: ffff880854695500 R10: ffff880854695500 R11: 0000000000000001 R12: ffff880854695a28 R13: ffff880854695a28 R14: ffff880854695a28 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffff88107fde0000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000002b43256a960 CR3: 00000000016b5000 CR4: 00000000000607f0 Stack: ffff8808546b3ed8 ffffffff8100aec9 ffff8808546b3f10 ffffffff8109ce25 334ab55852ec7aef 000000000000001f ffffffff8102d6c0 0000000000000000 0000000000000000 ffff8808546b3f48 ffffffff810276e0 ffff8808546b3f28 Call Trace: [<ffffffff8100aec9>] arch_cpu_idle+0x20/0x2b [<ffffffff8109ce25>] cpu_startup_entry+0xed/0x138 [<ffffffff8102d6c0>] ? flat_init_apic_ldr+0x80/0x80 [<ffffffff810276e0>] start_secondary+0x2c9/0x2f8 I compiled the kernel myself and it works fine, if I boot with nolapic. Yet, only one core is used. Also, the kernel of RHEL6 seems to work fine. I suspect that there are some patches used to make things work. Using the kernel config file from RHEL6 and building a more recent kernel yields the same problems. On the Xeon machine, things got better by disabling Hyperthreading completely. The machine now boots successfully on at least 4 out of 5 times. And if it boots, multicore stuff works just fine. However, I'm wondering about what to do about the AMD machine. So to sum it up: Gentoo kernel 3.6 - 3.11 won't reliably boot those machines unless you reduce the amount of cores (e.g. via nolapic). RHEL6 kernel (which is 2.6.32) boots just fine. RH kernel config used to build a 3.x kernel won't yield a working kernel. Not distribution specific (apart from the kernel being used). These stack traces got printed every minute or so. The kernel seems to be stuck in an endless loop. Yet, a recent kernel is needed for various reasons. So the question is: What does the RHEL6 kernel do, what vanilla or gentoo kernels don't do? Is there a boot option that might lead to a reliable boot with all the cores enabled? Best, Adam

• Three ways to upload/post/convert iMovie to YouTube [closed]

  - by alexyu2010

  For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.

• Enterprise desktop antivirus without a Windows server

  - by Adam

  Are there any desktop antivirus products suitable for use in an enterprise environment without a Windows server? We're currently using McAfee for our Windows desktops but to get updates and alerts with the latest version it looks like you need to be running their EPO server software. I'd like to avoid the cost of hardware and Windows licensing, and if possible to run just client-based antivirus. Ideally it would support: Updates from an internal copy of the definitions (e.g. a wget mirror) Automated configuration of the install Alerts from the client via email
