• Connect to wired and wireless networks at same time, Ubuntu

  - by Gary Chambers

  Currently, I have a media PC running Ubuntu 10.04 that I am trying to connect via a wired network cable directly to a NAS box, and wirelessly to the router. This works no problem after I run sudo /etc/init.d/networking restart but I can't get both interfaces to come up on system startup. My /etc/network/interfaces file reads as follows: auto eth0 iface eth0 inet static address 10.0.1.2 netmask 255.255.254.0 broadcast 10.0.1.255 network 10.0.1.0 auto wlan2 iface wlan2 inet dhcp As I say, I know this works, because I can get it to work by restarting the network interfaces, but I can't bring them both up on system startup. Does anyone know why this might be?

• LamedropXPd-like very simple zipper?

  - by overtherainbow

  Hello A friend of mine needs to zip a bunch of MP3's on her locked-down XP or Vista PC at work. There are two requirements: Since she doesn't have admin rights, the application should either not require an installer, or the installer doesn't require admin rights (don't know if it's possible) Ideally, the UI should be as dead-simple as eg. LamedropXPd, ie. just drag 'n drop files from Windows Explorer onto the icon, and off she has a ZIP file in the same directory as where the MP3's are located. Does someone know of such a utility? Thank you.

• Any opinions on Paragon's NTFS for Mac solution?

  - by AngryHacker

  I am currently using the free NTFS-3G to access my NTFS drive from the Mac. It seems pretty stable (except once in the very beginning, it locked up the Mac and corrupted my NTFS drive, which I then fixed with chkdsk from a PC). However, speed is NOT one of its virtues. I've been looking at buying Paragon NTFS for Mac OS X 7.0. Their product comparison PDF claims nearly double the speed (vs NTFS-3G) in almost every category (read, write, etc...). Can someone tell me whether the product is stable and whether the speed claims are true.

• Does anyone still use Iometer?

  - by Brian T Hannan

  "Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It is used as a benchmark and troubleshooting tool and is easily configured to replicate the behaviour of many popular applications." link text Does anyone still use this tool? It seems helpful, but I'm not sure if it's for the thing I am trying to work on. I am trying create a benchmark computer performance test that can be run before and after a Windows Optimization program does its stuff (ex: PC Optimizer Pro or CCleaner). I want to be able to make a quick statement like CCleaner makes the computer run 50% faster or something along those lines. Are there any newer tools like this one?

• cannot access new drive through nfs

  - by l.thee.a

  I am running nfs-kernel-server to access my files on my linux machine(ubuntu - /share). The disk I have been using is full. So I have added a new disk and mounted it to /share/data. My other pc mounts the /share folder to /mnt/nfs; but cannot see the contents of /mnt/nfs/data. I have tried adding /share/data to /etc/exports, but it did not help. What do I do? PS: I am looking for another solution than explicitly mounting /share/data on the second drive.

• How to quickly switch monitors on multi-monitor setup?

  - by Saxtus

  At my desktop PC, I have 3 displays hooked up on my Palit GeForce GTX 480 to extend my desktop: DVI: Samsung SyncMaster T220 (22" 16:10, 1680x1050, as my main) DVI: Samsung SyncMaster 940BF (19" 4:3, 1280x1024) HDMI: Sony Bravia KDL-32D3000 (32" 16:9, 1360x768) As expected, the GFX card can only utilize 2 of the displays at any given time, so I have to manually switch using Windows' "Display Properties" dialog, each time I want to switch between them. I've tried UltraMon, DisplayFusion and PowerStrip (so please don't refer me to a question where those are given as solutions) but they are unable to switch monitors. Instead they can only change display resolutions and settings on the existing active monitors, with specially weird results when I've saved the monitor states and then tried to switch monitors using the saved states! Any idea on how to bypass the awful "Display Properties" dialog and it's "confirm your change" timer?

• Unexpected network traffic?

  - by robwalker

  My internet connection is via a fixed wireless connection using a 900MHz Motorola Canopy module. The router reports a fairly consistent 32-64Kbps of incoming traffic on the WAN port. When I attached a PC directly to the port and run Wireshark, I get a dump showing a lot of chatter from other machines that I presume are connected to the same tower. This didn't include end-to-end traffic, but was there were a lot of ARP requests, SSDP traffic, ICMP and other network discovery type stuff. Is this 'normal' or does it suggest a misconfiguration somewhere? As far as I can tell there is no need for my modem to be receiving any of this traffic (other than wanting to know what the names of my neighbours machines and printers are!) Since the internet connection is slow at the best of time, having this amount of background noise seems very wasteful.

• What equipment do real ISP's use?

  - by Allanrbo

  In a dormitory of 550 residents, people often mistakenly set up DHCP servers for the whole network by plugging in their private Wi-Fi routers wrongly. Also recently, someone mistakenly configured their PC to a static IP being the same as that of the default gateway. We use cheap 3Com switches at the moment. I know that Cisco switches support DHCP snooping to solve the DHCP problem, but that still does not solve the default gateway IP takeover problem. What sort of switch equipment do real ISP's use so their customers cannot break the network for the other customers? What we ended up doing In case anyone are courious, we ended up doing seperate VLANs for each user. And as a matter of fact, not just the 550 users, but for 2500 users (11 dorms). Here's a page describing the setup: http://k-net.dk/technicalsetup/ (the section "Transparent firewall using VLANs"). There was no significant load on the router server as I feared in one of the comments below. Even at 800Mpbs.

• Hybrid drive not booting faster than a normal HD

  - by Nigel Trotter

  I have used Windows 7 to create an image of my existing standard 160GB HD and copied this image back to a bigger 500GB Seagate hybrid drive. After copying the image to the hybrid I had to resize the partition, which was fine but after rebooting a few times to "teach" the hybrid, I have no increase in boot speed. It still takes 20-25 seconds to close down and then over a minute to start up. Is this something to do with the way the image lays itself on the drive indiscriminately? Do I need to load the OS on the drive from scratch to get the benefits? My PC with an i5 processor, is using AHCI mode.

• Moving a VM from MS Virtual Server R2 to VirtualBox

  - by AngryHacker

  I have a Windows 2000 Professional VM happily running under MS Virtual Server R2 on WindowsXP. I need to move it to a different PC and the only one available is a Mac with VirtualBox on it. Theoretically, VirtualBox accepts .VHD files out of the box, but my attempts to run my VHD on VirtualBox resulted in failure. The Guest OS just keeps rebooting. I've attempted to get help on the VirtualBox forums, and they said that the VM image must first be prepped for the move, but could not give me any specifics. Anyone here know what is specifically involved in moving a Win2k .VHD to VirtualBox on the Mac?

• Windows 7 systeminfo reporting incorrect System Boot Time?

  - by rdingwall

  I work 9-5 and switch my PC off when I leave the office each day. When doing timesheets I need to know what time I got to work, so I usually use cmd systeminfo for finding the System Boot Time. Since upgrading to Windows 7 however, it's started reporting bizarre numbers between 11pm-2am instead of 8-9am. Today it says it booted at 11:34pm last night! I checked the event log and there is no entries between when I shutdown at 5:30pm yesterday and booted around 8am this morning. Has anyone else encountered this?

• Ultra-lightweight web browser?

  - by zildjohn01

  Are there any good super-lightweight graphical web browsers out there? I'd like to be able to browse the web on an old PC, but the mainstream crop of browsers is just too heavy, and I don't want to resort to something like Lynx. There must be something decent out there that'll fit in 16 or 32MB of RAM comfortably. 100% standards compliance isn't necessary, but I'd like something that supports the most widely used parts of CSS and JavaScript. The goal is to get 98% of sites usable in a nice, graphical format.

• Are there any sFTP clients that support a proxy that uses NTLM authentication?

  - by Iraklis

  The title pretty much summarizes the question. We have deployed an sFTP server that needs to be accessed from our client's MS Windows Pc's that reside within a restricted local area network. The only way they can get out for their Intranet is to use an HTTP proxy that requires NTLM authentication. From what I understand all open-source sFTP clients (FilleZilla,WinSCP,etc) do NOT support NTLM authentication (Because of legal issues). I know that there are workarounds to this (installing a local proxy at the machine that understands NTLM) but this would break all sorts of security policies of our client. So my question is : Does anyone know of any sFTP client that supports a NTLM Proxy?

• Configure Windows Routes for VPN

  - by Florin Sabau

  I have a Virtual PC/VMWare machine that runs Windows Server 2003. This virtual machine uses an IPSec VPN client program to connect to a remote network. I configured the virtual machine to have 2 NICs: NAT - to be used by the VPN Client to access the remote network Host only - to be able to access the virtual machine from the host The reason I have this setup is because I want to be able to access some remote network from the host machine. I could've installed the VPN client on the host machine, but the host runs Windows 7 and the client doesn't support it. The problem: although the virtual machine is normally reachable (ping + http access), as soon as the VPN client is started, neither of the NIC addresses are reachable anymore. I'm wondering if it is a routing problem that needs to be addressed? How do routing/VPN client connection affect the ability of the server to respond to client requests from the host?

• Cisco T1 Routing Help

  - by Joseph

  Thanks to someone on this site I was able to get the Serial0/0 interface up. I now have: DCD=up DSR=up DTR=up RTS=up CTS=up My next challenge seems to be in the routing and/or PC ip setup. This are the pertinent details from L3: WAN Network: 6.59.186.60/30 Level3 Side: 6.59.186.61 Customer Side: 6.59.186.62 Cust. LAN IPs: 6.59.192.224/27 What would be the IOS commands to setup this route correctly? Am I correct that I would the choose an IP like 6.59.192.224, subnet 255.0.0.0, gateway 6.59.186.62? Thanks

• Beam display from any computer to shared display

  - by rcourtna

  There are probably a lot of ways to skin this cat. Looking for the cleanest. In our office, we have a large display in a common area. We want to allow any computer in our office (mac, linux, windows) to output its video on the large display. Since some of the computers in the office are stationary, and it's not practical to run video cables everywhere, it would be preferable to make this all happen through the network. It is also possible for us to connect a dedicated (& networked) PC to the large display. How can I do this?

• Move virtual machine hard disk to a separate physical hard disk for better performance?

  - by joeeoj

  I have a dual-core machine with the host OS and many guest virtual OSs. Although I have 8GB of RAM, I notice a slowdown when I turn some virtual machine on (and it takes only 1GB RAM). I was told that I should move virtual machine hard disk file to a separate (another) physical hard drive in my PC to get better performance. This way the head of the hard disk would not have to jump from the virtual OS to the host OS as each hard drive would have its own head to deal with the OS: hard drive 1 head for host OS and hard drive 2 head for guest OS. Is this true? Should I get another hard disk only for virtual machine hard disk files?

• Logitech M185 Wirless Mouse issue

  - by Elliot Harrison

  An issue with a Logitech M185 mouse today. A user is unable to use the device. The device works perfectly fine on my PC (It appears as HID-compliant mouse), but not on her laptop. It does not appear in her device manager on the 'Mice and other pointing devices' section. I did notice an unknown device in the Universal Serial Bus Controllers section, but when I try to update the driver, it says it has the most up to date driver. We've tried plugging in the dongle in multiple USB slots but no luck. Any advice? It's a HP 620 Laptop on Windows 7. Thank you :)

• RDP for High DPI Monitors?

  - by Joey

  A client is having some problems with their laptop. They use RDP to remote into their work PC, but the laptop they are using is a small 13" Sony Vaio laptop, but with 1920x1080 resolution. Everything is pretty small on the laptop anyway, but the problem is much worse after connecting with RDP, where everything is almost unreadable. I have done the obvious with changing the resolution on the server, the RDP size, forced scaling on the terminal server etc, but nothing has worked. Something else which I would normally do is change the laptop resolution to something a little lower, but the laptop only has 2 resolution settings, the big one, and a 1024x768 (wrong ratio). Any ideas?

• Can't get any SMART or temperature data from HDDs

  - by Regs

  I have a PC with recently installed Gigabyte GA-X79-UD5 MB. I've encountered some weird problem with getting SMART data or temperature for HDDs. Every single tool I've tried in Windows 7 just can't get any data (HDTune, AIDA64...). I was suspecting that SMART feature is disabled in BIOS but it's seems like there is no such option in BIOS settings. I've even tried to update BIOS but still no luck. Same issue with both controllers on that MB (Intel and Marvell). It seems unlikely that both controllers end up with exact same issue. Both controllers are working in AHCI mode. Is there anythig that can interfere with getting SMART ant temp data from HDDs? Or is there any way to check that it's actuall MB issue? Is it even possible that it is hardware issue since all HDDs seems to work normal despite the fact that I can't get any temperature or SMART data from it.

• Wireless card not found on Ubuntu

  - by idealflip

  Hello all, I'm trying to setup Ubuntu on an old PC. I ran the following command, lspci, in order to get info on the wireless card installed. 00:0a.0 Ethernet controller: Marvell Technology Group Ltd. 88w8335 [Libertas] 802.11b/g Wireless (rev 03) Does anyone know where I can get drivers for this card/chip? And also, how to install (I'm rather new to linux). Also, I'm sure the card is working because I just formatted over xp, and everything was working well. Thanks in advanced!

• Python multithreading not working on VPS server

  - by Sabirul Mostofa

  I am running an python multithreaded application with multiple processes which scrapes data from some websites. While running on my localhost It works great, but on the vps server I am using( Centos 5.8, 2.6 GHZ with 4 cores) performs very slow. From the nethogs command I get the network usage too low. I get around 8KBps with 15 threads. On other hand, in my PC I get the usage around 100-120KBPS. I have read about the Python GIL and threading limitations. It seems GIL never releases the lock on the VPS though it should while doing I/0 Is there any configuration in the VPS that I need to change for the threading to work properly?

• Suggestions for a SOHO/Home Asterisk system

  - by James

  I would like to buy a small embedded system that runs Linux and Asterisk. I would like two FXS ports ( to plug analogue phones into ) and one FXO port ( to plug in to my real line to allow access to the POTS ). I would like it to have a USB port to hold storage for voicemail. I really want it for home use so I would like it to be under £150 ( say $250 ), given that you can buy ADSL routers for around this much can any of them be made to run Linux and Asterisk? I don't want a PC as the power usage would be too high. I am looking for something like this ASDL router but open and able to run Asterisk or another open PBX. At worst I would like a box which had one FXO and two FXS and just made them completely available over IP to a full Asterisk system on a low power Atom system.

• Why do I get "General Failure" when pinging host name on a Win 7 node on the network?

  - by hydroparadise

  This is a very peculiar problem with a station on our network. The client pc is running Windows 7 Pro. What makes this problem interesting is that this client is the only node on the network that seems to be experiencing this proglem. When I try to ping a specific Win 08 server by host name, I get an IPv6 address and get General failure. But when I ping it's IPv4 address, it responds just fine. My first thought would check the DNS server the name resolutions to see what would be going on, but the problem begs the quesion, why does the station get an IPv6 address back and fails as opposed to using the IPv4 settings (which are static btw). What gives? I am including a screen shot of trying the one specific server and failing while trying another server with success. All other nodes on the network don't have problems communicating with the server the one station is having issues with.
