• Unable to mount XP share using fs-cifs from Linux

  - by MetalSearGolid

  I have a head unit that runs Linux that is connected to my PC via an Ethernet cable. I have a Windows XP share on this PC that the head unit needs to be able to mount, however, when mounting using the following command, it fails. Here is the command that fails, along with the verbose output: # fs-cifs -vvvvvvvvv -l //CUMBRIA-XP:192.168.1.2:/hnet /mnt/net cifs[2158679-1]: starting... cifs[2158679-1]: user is to input both name & passwd. cifs[2158679-1]: server [192.168.1.2] share [hnet] prefix [/mnt/net] user [nu ll] passwd [null] Welcome: 192.168.1.2(:/hnet) -> /mnt/net Username:headunit cifs[2158679-1]: user name: headunit length 8 cifs[2158679-1]: new server Password: cifs[2158679-1]: establishing connection to (192.168.1.2)CUMBRIA-XP cifs[2158679-1]: session request: 192.168.1.2:CUMBRIA-XP -> localhost cifs[2158679-1]: negotiating smb dialect cifs[2158679-1]: skey(idx=2): 00000000, challenge:(8), 6137bfa2 f2d7803b cifs[2158679-1]: negotiation: success with dialect=2 cifs[2158679-1]: logging headunit on 192.168.1.2 cifs[2158679-1]: new packet cifs[2158679-1]: returning: mid 0 status= 0 cifs[2158679-1]: smb_logon successful: dialect 2 enpass 1 cifs[2158679-1]: mounting 192.168.1.2:/hnet cifs[2158679-1]: returning: mid 1 status= 13 cifs[2158679-1]: smb_mount: Bad file descriptor cifs[2158679-1]: try upper case share. cifs[2158679-1]: session request: 192.168.1.2:CUMBRIA-XP -> localhost cifs[2158679-1]: negotiating smb dialect cifs[2158679-1]: skey(idx=2): 00000000, challenge:(8), 2d3e910f e3e148c4 cifs[2158679-1]: negotiation: success with dialect=2 cifs[2158679-1]: logging headunit on 192.168.1.2 cifs[2158679-1]: returning: mid 2 status= 0 cifs[2158679-1]: smb_logon successful: dialect 2 enpass 1 cifs[2158679-1]: mounting 192.168.1.2:/HNET cifs[2158679-1]: returning: mid 3 status= 13 cifs[2158679-1]: smb_mount: Bad file descriptor cifs[2158679-1]: mount failed. cifs[2158679-1]: io_mount: smb_connection failed: Bad file descriptor io_mount: Bad file descriptor cifs[2158679-1]: user is to input both name & passwd. fs-cifs: missing arguments, or all mount attempts failed. run "use fs-cifs" or "fs-cifs -h" for help. Any ideas? It is worthy to note that /mnt does not exist on the filesystem, but I was told by the company who gave us these units that fs-cifs should automatically create the /mnt/net folders if they don't exist.

• missing files after reassemble of RAID-5

  - by Kris_R

  I had to open my file-server's housing on Sunday to replace a faulty fan. What I didn't see was that one of the sata-cables was not properly connected. The 1st thing I did after a reboot was a check of the RAID status and it showed immediately that one drive is missing. Till this moment the device was not used (however it was mounted, so I'm not 100% sure that system did nothing). I stopped md0 and re-plugged the cable: mdadm --stop /dev/md0 poweroff After another reboot I checked the removed drive: mdadm --examine /dev/sdd1 ... Checksum : 3276bc1d - correct Events : 315782 Layout : left-symmetric Chunk Size : 32K Number Major Minor RaidDevice State this 0 8 49 0 active sync /dev/sdd1 0 0 8 49 0 active sync /dev/sdd1 1 1 8 65 1 active sync /dev/sde1 2 2 8 33 2 active sync /dev/sdc1 3 3 8 17 3 active sync /dev/sdb1 I was a bit surprised that it was shown as active (even if earlier mdadm said, that this device was removed from array) and its checksum was OK. I recreated RAID with: mdadm --assemble /dev/md0 --scan The command mdadm --detail /dev/md0 showed that all drives were running and system was in "clean" state. I mounted the device md0 and then came hic-cup. I wanted to work on one of the last files that I had been using before all the situation and it was not there. In another place I missed actually all files from the directory where I was working. As far as I can see most of the files that are older than a few days are intact but some newer ones are missing. Now the big question: what would be your advice? Is there a way to get these data? I thought about removing the drive that was earlier labeled by mdadm and rebuild array with another empty HDD. I've found that after re-assemble the "broken" drive has another label (changed from sdd to sdb). Can this have influence on rebuilt process? If yes, how to reassemble the array properly? I'm sure the SATA-cables are connected still in the same order to the controller. p.s. Please no advises like "restore from backup". I'm doing back-ups on Sunday's night and this happened in the late afternoon, so backup is not really options for me. p.s.s. I asked this question on Unix&Linux but no answer came up during last two days. I'm getting quite anxious. Sorry for duplicating if any of you reading the other forum.

• DNS problems with Google on Windows 7

  - by awishformore

  Hello dear superuser community. I had no idea where to post this because it is a problem that completely baffles me. I have a lot of experience with network configuration, but I am completely out of ideas on how to fix this. I have a Fritz!Box branded router on my ISP 1&1 in Germany. My computer is connected to it with a normal Ethernet cable. I always manually set my IP on the computer and use the Google DNS servers for name resolution. I also tried OpenDNS and the result is the same. With that configuration the following happens: Google search responds with big delay Gmail, Google Calendar & Google Drive requests time out the majority of the time In order to troubleshoot, I set the network connection to DHCP for both IP & DNS. At that point, what happens is the following: Google search times out most of the time Gmail, Google Calendar & Google Drive work most of the time Sometimes, it happens that the sites that time out will come up, but weirdly enough, the pictures on the buttons will be missing. For instance, the magnifying glass on Google will be gone or the circle arrow on Gmail (but all buttons of course). All other websites load just fine - and very quickly. All other network functionality is completely unimpacted. The behaviour of fixed IP & Google DNS vs automatic IP & DNS is easily reproducible. I am going crazy trying to fix this as I have no idea what the hell is going on at this point. Here a list of the things I have tried thus far: Flushed the DNS Tried on different browsers (Works fine on my laptop by the way) Tried disabling Teredo & IPv6 stack Emptied all caches Checked the HOSTS file Rebooted the router Reset the router Reinstalled the network adapter Tracert displayes normal route until timing out at one point Ping usually doesn't work for the unreachable sites either Ran both complete Norton 360 & Kaspersky 2012 scan Ran Kaspersky Virus Removal Tool in safe mode Tried connection in safe mode & networking enabled If you have any ideas, please let me know. I'm getting desperate...

• Windows Server 2003 IPSec Tunnel Connected, But Not Working (Possibly NAT/RRAS Related)

  - by Kevinoid

  Configuration I have setup a "raw" IPSec tunnel between a Windows Server 2003 (SBS) machine and a Netgear FVG318 according to the instructions in Microsoft KB816514. The configuration is as follows (using the same conventions as the article): NetA | SBS2003 | FVG318 | NetB 10.0.0.0/24 | 216.x.x.x | 69.y.y.y | 10.0.254.0/24 Both the Main Mode and Quick Mode Security Associations are successfully completed and appear in the IP Security Monitor. I am also able to ping the SBS2003 server on its private address from any computer on NetB. The Problem Any traffic sent from a computer on NetA to NetB, or from SBS2003 to NetB (excluding ICMP Ping responses), is sent out on the public network interface outside the IPSec tunnel (no encryption or header authentication, as if the tunnel were not there). Pings sent from a computer on NetB to a computer on NetA successfully reach computers on NetA, but the responses are silently discarded by SBS2003 (they do not go out in the clear and do not generate any encrypted traffic). Possible Solutions Incorrect Configuration I could have mistyped something, somewhere, or KB816514 could be incorrect in some way. I have tried very hard to eliminate the first option. Have re-created the configuration several times, tried tweaking and adjusting all the settings I could without success (most prevent the SA from being established). NAT/RRAS I have seen multiple posts elsewhere suggesting that this could be due to interaction between NAT and the IPSec filters. Possibly the NetA private addresses get rewritten to 216.x.x.x before being compared with the Quick Mode IPSec filters and don't get tunneled because of the mismatch. In fact, The Cable Guy article from June 2005 "TCP/IP Packet Processing Paths" suggests that this is the case, (see step 2 and 4 of the Transit Traffic path). If this is the case, is there a way to exclude NetA-NetB traffic from NAT? Any thoughts, ideas, suggestions, and/or comments are appreciated. Update (2011-06-26) After failing to solve the problem, I resorted to paid Microsoft support. They were unable to solve the problem. Since then I have implemented a solution based on Linux that is working quite well. I will attempt to evaluate any proposed answers as best I can, but current configurations and time constraints will make this slow...

• OS X Snow Leopard 10.6 Refuses to Load Websites the first time intermittently

  - by Brandon

  Many times when I am browsing the web, Snow Leopard will sit and load a site for 20 seconds or more, until it times out and says it cannot be displayed. If I refresh, it loads RIGHT away, every time. The issue is intermittent but happens from once every couple of days to a few times a day. So the long and short of it is this: Aluminum MacBook (Non-Pro) 2.4GHz Core2Duo, 4GB DDR3 I am using 10.6.6 but I have had this issue since 10.6.0 It happens in Firefox, Chrome, and Safari I have flushed my DNS (using the command 'blablabla flush') I am using custom DNS servers which I hoped would fix it but it had no effect* I am running Apache currently but haven't been for most of the time I've reformatted multiple times, always experiencing the issue I am on Cox cable internet, with a Motorola Surfboard & a Belkin F6D4230-4 v1 (Pre?) N wireless router. I've put the router in G only & N only & G+N to no effect It seems to be domain dependant as I can sometimes load the Google cache right away, and sometimes other sites will load but Google will refuse My Powerbook G4 with Leopard, other Windows XP laptops, & my wired Win7 desktop do not suffer from the issue. *I recently started using these to escape the awful Cox redirect page on timeouts I'm almost positive the issue has happened on other networks but I can't recall a specific instance (I have a terrible memory). The problem is intermittent and fixable enough (I just have to wait until it times out and hit refresh one time) but incredibly annoying since I'm constantly reading documentation from a large variety of sites. EDIT: To clarify, this happens with ALL sites, not only specific sites. I haven't been able to detect any pattern to the failures, but one day Google.com will refuse to load while reddit.com will, and the next day vice versa. Keep in mind that waiting for a timeout and hitting refresh loads the page right away, every time. If I don't wait for the timeout, opening more links, hitting refresh, and clicking the link a billion times have no effect. It seems to be domain neutral, affecting sites seemingly at random. It doesn't seem to have anything to do with connection inactivity either, because I will be SSHed into different servers, uploading files, browsing, downloading, etc, and it will just quit loading Jquery.com (for example) until I sit and wait for a timeout. /EDIT This is my last resort. Please, someone, tell me what is happening. Thank you.

• USB ports causing Wireless and Mobile Phone tethering drop out

  - by chrolli

  I have a problem with my USB ports and I can't seem to pinpoint the problem. I'm hoping that I can get some idea as to how to troubleshoot my problem. Problem description: I recently bought a USB Wireless Adapter in order to connect my Desktop PC to the WLAN. The dongle keeps dropping off connection regularly on average once a minute. And the connection is slow. What I've tried: I installed a network scanner to determine signal strength. The PC/adapter combo is getting about 70% signal strength. I have a laptop that has an internal Wireless adapter. I moved the laptop near the location of the PC. The signal strength was above 90%. I installed the USB adapter on the laptop. I placed the laptop near the location of the PC. The signal strength was above 80%. And there is no drop out issue. I've isolated the problem to be on the PC. I used internet tethering on my mobile phone in order to test the USB ports. I get the same problem, themobile phone keeps dropping in and out. I plugged the adapter and phone on all USB ports, and it is still dropping out on all ports. I've isolated the problem to be the Motherboard, USB hub. I updated the BIOS, and USB driver. Still dropping out. I noticed that when I used the mobile phone tethering method, the phone (iphone 5) is guarenteed to drop out and does not appear to charge if I jiggle the the 8-pin connector on the base of the phone. If I push the pin tightly on the phone, the phone starts charging, as soon as I let go, it stops and drops out from the PC. This is strange because this doesn't happen when it is plugged to the powerboard. Which means that the 8 pin connector is fine. I'm not sure what the problem is. I assume that it is to do with the USB ports not supplying enough power which in turn causes the devices to intermittently drop out. The reason I say this is because the USB cable works fine when plugged into a powerboard with enough power supplied to the phone. Only when it is plugged into the USB port on the PC, does it drop out. My motherboard is Asus P8z68-v le. My Wireless adapter is the D-link DWA131. I can't seem to find any settings in the BIOS to increase the south bridge voltage so as to supply more power to the USB ports. Although this problem only occurs when I'm trying to hook up to a device supplying internet connection. My USB HDD, Flash drives, and Mouse and Key are working fine! Any suggestions please?

• OpenBSD pf 'match in all scrub (no-df)' causes HTTPS to be unreachable on mobile network

  - by Frank ter V.

  First of all: excuse me for my poor usage of the English language. For several years I'm experiencing problems with the 'match in all scrub (no-df)' rule in pf. I can't find out what's happening here. I'll try to be clear and simple. The pf.conf has been extremely shortened for this forum posting. Here is my pf.conf: set skip on lo0 match in all scrub (no-df) block all block in quick from urpf-failed pass in on em0 proto tcp from any to 213.125.xxx.xxx port 80 synproxy state pass in on em0 proto tcp from any to 213.125.xxx.xxx port 443 synproxy state pass out on em0 from 213.125.xxx.xxx to any modulate state HTTP and HTTPS are working fine. Until the moment a customer in France (Wanadoo DSL) couldn't view HTTPS pages! I blamed his provider and did no investigation on that problem. But then... I bought an Android Samsung Galaxy SII (Vodafone) to monitor my servers. Hours after I walked out of the telephone store: no HTTPS-connections on my server! I thought my servers were down, drove back to the office very fast. But they were up. I discovered that disabling the rule match in all scrub (no-df) solves the problem. Android phone (Vodafone NL) and Wanadoo DSL FR are now OK on HTTPS. But now I don't have any scrubbing anymore. This is not what I want. Does anyone here understand what is going on? I don't. Enabling scrubbing causes HTTPS webpages not to be loaded on SOME ISP's, but not all. In systat, I strangely DO see a state created and packets received from those ISP's... Still confused. I'm using OpenBSD 5.1/amd64 and OpenBSD 5.0/i386. I have two ISP's at my office (one DSL and one cable). Affects both. This can be reproduced quite easily. I hope someone has experience with this problem. Greetings, Frank

• Cannot access a very specific site from my router

  This is a problem for me because this site is important to me. It's MY website. And sadly my email is hosted on my site (which I cant access either) When I try to access my website when connected to my Linksys E3000 router, these days it simply just doesn't go through.

So I'm at a bit of a loss what to do here, as NO device (Computers, Laptops, Tablets, Phones, PS3/ 360, etc) can access my site or its features, so it's not just my computer either. But every other site is just fine. When I connect to my neighbors router, the site comes up just fine. And shes with SHAW as well. What should I do?!

• What are some of the best wireless routers for a price-conscious home power-user?

  - by Alain

  I'm extremely dissatisfied with the 'popular' choice for routers in homes and small offices. They are expensive (upwards of 60$), lack a great deal of useful configuration options, and seem to need to be restarted quite often. (Linksys comes to mind). I've been on the market for a good router lately, and slowly collecting a set of requirements I feel good routers should meet. Maximum number of TCP/IP connections. - This isn't something I see any routers advertise, but in terms of supporting torrent applications, I've been screwed by routers that support less than 20 here. From what I understand a fairly standard number is 200, but there are not so expensive routers that support thousands. Router configuration menu - Most have standard menu's that let you set up basic things like your wireless network encryption settings, uPnP, and maybe even DMZ (demilitarized zones). An absolute requirement for me, however, are routers with good enough firmware to support: Explicit Port forwarding Assigning static local ips to specific mac addresses, or at least Port forwarding by MAC address Port, IP and MAC filtering Dynamic DNS service for home users who want to set up a server but have a dynamic IP Traffic shaping (ideally) - giving priority to packets from certain machines or over certain ports. Strong wireless signal - If getting a reliable signal requires me to be so close to the router that I can connect an Ethernet cable, it's not good enough. As many Ethernet ports as possible. - Because I want to be able to switch from console gaming to PC gaming without visiting my router. So far, the best thing I've stumbled upon (in the bargain bin at staples) was a 20$ retail plus router. It was meant to be the cheapest alternative until I could find something better to purchase online, but I was actually blown away by the firmware capabilities. It supports defining reserved bandwidth for certain network traffic, dynamic DNS, reserving local IPs for specific MAC addresses, etc. At 2 am when my roommate is killing our Internet with their torrents, I can limit their bandwidth without outright blacklisting them. I have, however, met serious limitations when it comes to network traffic between local machines. It claims a 300Mbps connection, but I have trouble streaming videos from my PC to my console or other laptops wirelessly. It has a meltdown and needs to be reset once in a while (no more than a couple times a month), and it's got a 200 connection limit. There 4 Ethernet ports in the back but I'm pretty sure the first doesn't work. So some great answers to this question would be: Any metrics you use to compare routers, and requirements you have for new candidates. The best routers you've found for supporting home servers, file management systems, high volume torrent traffic, good price/feature ratio, etc. Good configuration advice (aside from 'use Ethernet whenever possible') Thanks for your feedback and experiences!

The screen that we have registers that it is connected to something (by not displaying the screen it does when the cable is unplugged) but just remains blank, no output at all. I recently took the card to my University and one of my friends who is better with hardware issues than I am tried it in his system and it worked perfectly. No issues whatsoever. I do not have a spec list for his system but I could get one if you need it. If you need any more information on this issue I will be happy to supply you with it as I am starting to get very annoyed with this problem ^_^

• Choosing my first Domain Registrar?

  - by user36914

  This will be the first domain i've ever registered. So i'm at a loss what to look for. I definitely don't want to go with GoDaddy. Here are my requirements: Must have unlimited email forwards for my domain Easy to transfer away if i choose. Must not be one of those shady registrars that will try to auction your domain at the end. Ability to create sub domains Domain Registration is Private I would like a domain registrar that would let me use my dynamic ip of my ISP (Cable) if i want to. So hopefully they would have some type program that would detect IP changes and update accordingly So i've looked at a variety of registrars so far. The three left were really NameCheap, DreamHost, & DomainMonster. I have heard good things about DreamHost but i think its off the list because they don't give you any information about the features you get when you register your domain with them. They have a "Whats included" button the page but it mainly list the features with hosting not registration. DomainMonster looks pretty cool but i don't see anything about subdomains. Also i would assume they don't have a system for dynamic ip address updating. So you would have to constantly check that your ip of your ISP has changed or not and update it manually. NameCheap also looks nice. There are two things i really like about them. Right on their feature page they list "Free Dynamic DNS With Client" which is pretty cool. They also have a free SSL certificate for the first year. Haven't messed a lot with certificates but this would definitely be something i would use. Only minus i can see is you only get free private whois for the first year. After that its $2.99 which isn't that big of a deal. I'm leaning towards NameCheap now. Is this a good choice. Is there anything else i should be looking at?

• Ubuntu box static routing problem

  Hello, I'm trying to configure a ubuntu server to be a router. This is my interface configuration (eth2 connects to my WAN, eth0 to my LAN): auto eth2 iface eth2 inet static address 192.168.0.249 netmask 255.255.255.0 gateway 192.168.0.1 broadcast 192.168.0.255 auto eth0 iface eth0 inet static address 192.168.100.1 netmask 255.255.255.0 This is the router information: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2 0.0.0.0 192.168.0.1 0.0.0.0 UG 100 0 0 eth2 And this is dhcp configuration: subnet 192.168.100.0 netmask 255.255.255.0 { range 192.168.100.101 192.168.100.254; option domain-name-servers 201.70.86.133; option routers 192.168.100.1; authoritative; } I'm then connecting a mac os x by cable on eth0.

• HP MSR 30-10a Router - Route Traffic over Default Route

  - by SteadH

  We have a brand new HP MSR 30-10a Router. We have a fairly simple routing situation - we have two IP blocks, one which has a route out. We need things on the first block to go through the router, and out. I have an old Cisco 2801 router doing the job right now. For our example - IP Block 1: 50.203.110.232/29, Router interface on this block is 50.203.110.237, route out is 50.203.110.233. IP Block 2: 50.202.219.1/27, Router interface on this block at 50.202.219.20. I have a static route created for: 0.0.0.0 0.0.0.0 50.203.110.233 The router seems to understand this. When on the CLI via serial cable, I can ping 8.8.8.8 and hear responses from Google DNS. Woo hoo! The issue arrives when any client sits on the IP Block 2 side. I configured my client with a static IP of 50.202.219.15/27, default gateway 50.202.219.20. I can ping myself. I can ping the near side of the router (50.202.219.20), and I can ping the far side of the router (50.203.110.237. I cannot ping anything else in IP block 1, nor can I ping 8.8.8.8. Here is my configuration file: <HP>display current-configuration # version 5.20.106, Release 2507, Standard # sysname HP # domain default enable system # dar p2p signature-file flash:/p2p_default.mtd # port-security enable # undo ip http enable # password-recovery enable # vlan 1 # domain system access-limit disable state active idle-cut disable self-service-url disable # user-group system group-attribute allow-guest # local-user admin password cipher $c$3$40gC1cxf/wIJNa1ufFPJsjKAof+QP5aV authorization-attribute level 3 service-type telnet # cwmp undo cwmp enable # interface Aux0 async mode flow link-protocol ppp # interface Cellular0/0 async mode protocol link-protocol ppp # interface Ethernet0/0 port link-mode route ip address 50.203.110.237 255.255.255.248 # interface Ethernet0/1 port link-mode route ip address 50.202.219.20 255.255.255.224 # interface NULL0 # ip route-static 0.0.0.0 0.0.0.0 50.203.110.233 permanent # load xml-configuration # load tr069-configuration # user-interface tty 12 user-interface aux 0 user-interface vty 0 4 authentication-mode scheme # My guess right now is there is some sort of "permission" needed to use the default route. The manuals haven't turned up a lot in this area that don't make the situation much more complicated (but maybe it needs to be more complicated?) Background: we use HP switches, and I love the CLI. I bought HP thinking the command line interface would be similar, or at least speak the same language. Whoops! I'd be happy to provide more information or perform any additional tests. Thanks in advance! Update 1: The manual mentions routing rules. I hadn't previously added these (since our Cisco 2801 seems to route anything by default). I added: ip ip-prefix 1 permit 0.0.0.0 0 less-equal 32 alas, still no dice.

• CPU overheating after cleaning it

  - by Roberts

  I wanted to clean my computer CPU heatsink and fan itself, because the temperature is not what I wanted. About (50C ~ 70C). I have Intel Core 2 Duo E4300 @1.8 GHz (LGA775). The heatsink wasn't so scary filled with dust but I wanted to clean it anyway. I didn't know how to get heatsink with fan from the socket. So after 25 minutes I've figured it out. But I didn't know how to get it back on so I spent a lot time getting out the motherboard from the case. The fan and heatsink... The case and all components are clear of dust. (I'm tired now). Then I put all back just the way it was, well did few things on cable management. But the problem was that I didn't know how to connect front audio connectors. I had Windows XP hibernated. So I started the PC and everything was normal, except CMOS memory was clear. I configured the BIOS just the way it was and while I was doing that I saw about 58C CPU temperature and fan at 1789 RPM. Restarted the computer with new settings applied. But Windows halted with Blue Screen (I forgot what error it was but something with KERNEL). Restarted the PC and deleted hibernation session and everything was back normal. But couldn't record any sound from front panel microphone. The problem was that I messed ground wire with mic. Again after fixing it I turned computer on. No problems. The fan currently is noisy and temperature was 78C. The temperature before was 55C - 60C at idle. Now it's about 60C. If I do something then temperature raises to 79C. While speaking in skype the temperature was 82C. Could this problem occur because of the thermal grease (it's old and never replaced)? Edit The problem wasn't in thermal paste (because I didn't touch it). The problem was that I installed heatsink wrong. Now instead of regular 60C CPU temperature the CPU is at 48C (cool).

• DVD ROM is not working

  - by Cyril N.

  (note: I don't know in which StackExchange site to put this question, I'll thank the moderator that will move it to a more appropriate place, if there is a S.E. available for my question). I have a DVD RW drive that is well listed in the bios, and if no CD is in, it is also present in the "My Computer" of my Fedora 16. But when I put a disc on it, the icon disapear from "My Computer", and I can not do anything with this ! (Like erasing a RW disc). I'd like to boot a Fedora 17 Live CD image. I burned it on an other computer but when I try to run it in bios, nothing is done and I'm redirected to Grub of my HD.

• Wake On Lan only works on first boot, not sequent ones

  - by sp3ctum

  I have converted my old Dell Latitude D410 laptop to a server for tinkering. It is running an updated Debian Squeeze (6) with a Xen enabled kernel (I want to toy with virtual machines later on). I am running it 'headless' via an ethernet connection. I am struggling to enable Wake On Lan for the box. I have enabled the setting in the BIOS, and it works nicely, but only for the first time after the power cord is plugged in. Here is my test: Plug in power cord, don't boot yet Send magic Wake On Lan packet from test machine (Ubuntu) using the wakeonlan program Server expected to start (does every time) Once server has booted, log in via ssh and shut it down via the operating system After shutdown, wake server up via WOL again (fails every time) Some observations: Right after step 1 I can see the integrated NIC has a light on. I deduce this means the NIC gets adequate power and that the ethernet cable is connected to my switch. This light is not on after step 4 (the shutdown stage). The light becomes back on after I disconnect and reconnect the power cord, after which WOL works as well. After step 4 I can verify that wake on lan is enabled via the ethtool program (repeatable each time) This blog post suggested the problem may lay in the fact the motherboard might not be giving adequate power to the NIC after shutdown, so I copied an acpitool script that supposedly should signal the system to give the needed power to the card when shut down. Obviously it did not fix my issue. I have included the relevant power settings in the paste below. I have tried different combinations of parameters of shutdown (the program) options, as well as the poweroff program. I even tried "telinit 0", which I figured would do the most direct boot via software. If I keep the laptop's power button pressed down and do a hard boot this way, the light on the ethernet port stays lit and a WOL is possible. I copied a bunch of hopefully useful information in this paste I have tried this with the laptop battery connected and without it. I get the same result. Promptly pressing the power button causes the system to shut down with the message "The system is going down for system halt NOW!", and WOL is still unsuccessful.

• windows server 2008 r2 remote desktop issue with roaming clients

  - by Patrick D'Haese

  I have the following situation : a Dell windows server 2008 R2 computer, with remote desktop services installed. I have installed a java application making use of a PostgreSql database, and made this application available for clients using RDP. Clients are standard Win XP pc's and Psion Neo handheld devices running Windows CE 5 Pro. The application works fine for clients on standard XP pc's connected directly via cat 5E Ethernet cable to a Dell Powerconnect 2816 switch. The Psion Neo clients connect wireless to the network via Motorola AP6532 access points. These access points are connected via a POE adapter to the same switch as the XP pc's. The Psion devices can connect without any problem and very quickly to the server and to the application using RDP. So far, so good. When the Psion devices move around in the warehouse, and they roam from one access point to the other, the RDP session on the client freezes for approx 1 minute, and then it automatically resumes the session. This freezing is very annoying for the users. Can anyone help in solving this issue? Update (August 9) : After re-installing the access points we have a working situation, but only when connecting to the RDP host : * via a Win Xp SP3 laptop * via a Symbol MC9190 Win CE 6 mobile device When roaming we notice a small hick-up less then 1 second, what is very acceptable. With the Psion NEO it's still not working, when roaming the screen freezes from 2 to 30 seconds. The RDP client on the win xp sp3 laptop and the symbol mc9190 is version 6.0. The RDP client on the neo is version 5.2. I have changed the security layer on the RDP host to RDP security layer (based on forums on the internet), because older RDP clients seem to have issues with the RDP 7.1 protocol on the Win server 2088 R2. Psion adviced us to do some network logging activity on the different devices. We made this logging via wireshark, and based on this the conclusion of Psion is that the server fails in handling tcp-requests. Can anyone give me a second opinion by analysing the wireshark loggings. Thanks in advance. Regards Patrick

• Problems when trying to connect to a router wirelessly

  - by Ruud Lenders

  The situation - At my girlfriend's parents' place there are six Windows 7 devices that are wired or wireless connected to a router: 3 dekstops and 3 laptops. There are also several smartphones using the router. The router is secured with WPA2 (AES). The problem - We never had any problems with the router for over a year. But recently - about 3 weeks ago - my girlfriend's laptop (HP) and my laptop (ASUS) started to develop problems while trying to connect to the router. The router has stopped showing up from the network list. Sometimes it comes back and shows up, but then it keeps saying something along the lines of "Could not connect", and not long after that it dissapears again. The range of the router is not the problem here, because we experience the same when we sit next to the router. Sometimes, if we are lucky, and waited a long time (10-15 minutes) without using the laptop for anything, the laptop will eventually succesful connect to the router. The attempts - Of course, the Window 7 troubleshooter. We tried troubleshooting the connection problems and the wireless network adapter, but no luck. We also reset the router enough times to know that's not helping either. Here's the full list of things we tried, but did not help: Running the Windows 7 troubleshooter Resetting the router (more than once) Setting the router settings to factory defaults Disconnecting all other devices except one laptop Applying a system restore Trying static/dynamic IP/DNS - Dynamic is better, right? Enabling/disabling IPv6 - Should I keep IPv6 disabled? Running the command: netsh wlan stop hostednetwork Running the command: netsh wlan set hostednetwork mode=disallow Updating/reïnstalling wireless adapter drivers The tests - To help finding the core of the problem, we tested the following: Plugging an ethernet cable in the router and in our laptops - worked fine Connecting someone else's laptop to the router (wireless) - worked fine Connecting our laptops to someone else's router - worked fine The router - This information might be relevant: Router model: Sitecom 300N Wireless Router Router hardware: version 01 The DCHP Server's IPs range from 192.168.0.100 to 192.168.0.200. Router settings: Wireless channel: 12 Channel bandwidth: 20/40 MHz Extension channel: 8 Preamble type: Long 802.11g protection: Disabled UPnP: Enabled The laptops - If you are wondering about our laptops: My laptop model: ASUS Pro64JQ Girlfriend's laptop: HP Pavillion G6 OS: Both Windows 7 Professional x64 - with Service Pack 1 My wireless adapter: Atheros AR9285 AdHoc 11n: Enabled The question - Does anyone have experienced the same problems as I do? Or does someone know how to solve this? Are there more tricks I can try, or settings I should change? Note - Our laptops are not slow or old. My laptop is 1.5 years old, and the other laptop is just 5 months old. I know how to keep laptops clean and I'm pretty sure both laptops are not bloated with useless software.

• ASA and cisco vs NSA sonic firewall

  - by Lbaker101

  Currently I’m trying to structure our network to fully support and be redundant with BGP/Multi homing. Our current company size is 40 employees but the major part of that is our Development department. We are a software company and continued connection to the internet is a requirement as 90% of work stops when the net goes down. The only thing hosted on site (that needs to remain up) is our exchange server. Right now i'm faced with 2 different directions and was wondering if I could get your opinions on this. We will have 2 ISPs that are both 20meg up/down and dedicated fiber (so 40megs combined). This is handed off as an Ethernet cable into our server room. ISP#1 first digital ISP#2 CenturyLink we currently have 2x ASA5505s but the 2nd one is not in use. It was there to be a failover and it just needs the security+ license to be matched with the primary device. But this depends on the network structure. I have been looking into the hardware that would be required to be fully redundant and I found that we will either of the following. 2x Cisco 2921+ series routers with failover licenses. They will go in front of the ASAs and either connects in a failover state or 1 ISP into each of the 2921 series routers and then 1 line into each of the ASAs (thus all 4 hardware components will be used actively). So 2x Cisco 2921+ series routers 2x Cisco ASA5505 firewalls The other route 2x SonicWalls NSA2400MX series. 1 primary and the secondary will be in a failover state. This will remove the ASAs from the network and be about 2k cheaper than the cisco route. This also brings down the points of failure because it’s just the 2x sonicwalls It will also allow us to scale all the way up to 200-400 users (depending on their configuration). This also makes so the Sonic walls. So the real question is with the added functionality ect of the sonicwall is there a point in paying so much more to stay the cisco route? Thanks!

• Why does unpartitioned Hitachi HDS5C3020 drive start consuming 50% more power 15 minutes after boot?

  - by Pro Backup

  In a Debian 6.0.6 system there are 74 pieces of 2TB Toshiba DT01ABA200 drives. These drives are identified as Hitachi HDS5C3020BLE630 drives running firmware revision MZ4OAAB0. 64 Drives attached via HP SAS expander cards to an LSI 2008 SAS controller, another 5 drives are connected directly to the mainboard, 4 drives are connected to a Sil based PCI controller and last 1 drive is only powered and has no data cable connected. The controller LSI and Sil card's their onboard BIOS are both disabled and the mpt2sas and sata_sil modules are removed from the Linux debian 2.6.32-5-amd64 #1 SMP Sun Sep 23 10:07:46 UTC 2012 x86_64 GNU/Linux kernel. The mpt2sas module is loaded after boot using a modprobe command in /etc/rc.local. These 74 drives are not partitioned, neither formatted and also not mounted. The system consumes: with 0 drives: 70.6 - 70.9 Watt (also 15 minutes after boot); with 74 drives: 330 - 360 Watt, just after boot (is equivalent to 3.5 - 3.9W per drive in idle state); with 74 drives: 420 - 466 Watt, each time in the 15th minute of uptime (is equivalent to 4.7 - 5.3W per drive in idle state). The drive specification lists 4.7W as read/write, and 3.3W as idle power consumption. The increased power consumption is most likely on the 5V line, because after roughly 1 minute an "over current protection" (OCP) of the power supply (PSU) shuts down the power. The used PSU is a single rail model with an OCP of 122A on the 12V line and 55A on the 5V line. Regression: It doesn't matter whether the drive its APM value is set to disabled or 1 (maximum power saving). The operating system records no read/write activity in /proc/diskstats. The values there are identical (28 read, 0 write operations) as immediately after the modprobe operation. Can't test what happens when booting into the mainboard it's BIOS - to exclude any OS intervention - because the Super Micro X8SI6-F mainboard running firmware 06/27/12 has a bug that incorrectly reads a +74.0 C CPU sensor temperature as "High" in BIOS mode, and shuts down the power after 1 minute. What might be causing the drive read/write activity on all drives in the 15th minute after boot and how to prevent it from happening?

• New monitor connected to HDMI adaptor doesn't show output after booting

  - by Paul

  Hello out there in the multiple monitors’ world. I am a very old newbie in your world and need help. I just purchased a new Asus VH236H monitor and hooked it up the HDMI port of an ATI Radeon HD4300 / 4500 Series display adaptor. I left the old Princeton LCD19 (TMDS) hooked up to the DVI port of the same display adaptor. Both monitors displayed the boot sequence, after I fired good old Sarastro2 (Asus P5Q Pro Turbo – Dual Core E5300 – 2.60 GHz) up. The Asus lacked one half of a second behind the Princeton until the Windows 7 Ultimate SP 1 boot up was complete. Then the Asus displayed “HDMI NO SIGNAL” and went into hibernation. The Princeton stayed lit up as before. Both monitors are displayed on the “Screen Resolution Setup Display” and I plaid around with them for a while. The only thing I accomplished was to shove the desktop icons from the Princeton to the still hibernating Asus. The “Multiple displays:” is set to “Extend these displays”, the Orientation is “Landscape” and the Resolutions are set on both to the “recommended” one. Both monitors show that they work properly in the advanced Properties display. What am I doing wrong, what am I missing? Never mind the opinions about the different resolutions of the two monitors. I always can unhook the Princeton and give it to a Goodwill Store if I do not like the setup. I just would like to make it work. Any constructive help is very much appreciated, Thank you. Thank you Anees Bakrain Only the ATI Radeon HD 4300/4500 Series adapter is displayed in the Device Manager, for that reason I have to assume that the onboard display adaptor is not active. All 40 drivers of Sarastro2 are up to date and the HDMI cable can not be the problem because both monitors displayed the boot sequence up to the moment when Windows 7 was loaded completely. This was the moment, when the Asus monitor lost its signal. Both connectors, HDMI and DVI are connected and removing the DVI connector would not solve my problem of running both monitors simultaneously. However, your suggestions shifted my seventy one year old brain into the next gear. The only question remaining is; “Why the signals to the Asus monitor stop after the sequence is complete”. The ATI Radeon HD 4300/4500 Series adapter seems to be capable of sending simultaneous HDMI and DVI signals, what is done during the boot sequence. Why do the signals change after the boot sequence is complete is the key question or der springende Punkt? Is this a correct assumption slhck?

• XP shared folders not accessible after BIOS changed

  - by stijn

  Here's what worked for over a year: PC A runs Windows 7, PC B runs Windows XP. Both are on the same subnet behind a router. A uses user account X, but logs in to PC B using the Administrator account. PC B is a Dell Precision 470. A known problem with these is that sometimes when plugging in their power cable they somehow loses all BIOS settings. This happened yesterday. After this happens Windows won't boot, because the default BIOS setting is 'RAID ON' while there is no RAID configured. No problem though, changing the BIOS settings to 'RAID OFF' makes it boot without problems. Note that in the meantime, nothing config-related was changed on machine A. It wasn't even on. Indeed after doing this, everything is fine. Everything includes all normal operations, remote desktop from PC A to PC B, running Synergy between A and B, accessing shared folders from B to A. But accessing the shared folders on B from A does not work any more. I tried pretty much everything I found via Google (fiddling with policies/registry kes/...) but no avail. > ping -a 192.168.2.2 Pinging A [192.168.2.2] with 32 bytes of data: Reply from 192.168.2.2: bytes=32 time<1ms TTL=128 > net view \\192.168.2.2 System error 5 has occurred. Access is denied. > net use /persistent:no K: \\A\myshare /user:A\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:192.168.2.2\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:USERNAME PASSWORD System error 86 has occurred. The specified network password is not correct. A solution to this would be great: I haven't been able to do any work since yesterday ;] update after taking the hard drive out of B and putting it in another Precision 470 with almost exactly the same hardware (at first sight, only the video card differs) the shared folders work.. Putting the disk back into A, same problem remains. Why does this depend on hardware, and more important, on which hardware?

• Possible capacitor plague - need help identifying

  - by cornjuliox

  I've been having some PC power issues lately, and I think I've tracked it down to a bad power supply. Lately, when I'm on my PC it will often restart without warning, displaying "Hypertransport sync flood error occurred last boot." once POST finishes. I've googled the error, but can't come to a definitive conclusion as to what's causing it. I've seen posts suggesting that it might be a power supply issue, but nothing conclusive. Here's what I've done so far: -I haven't installed anything suspect within the last 3 months. -I do overclock just a tiny bit, so I tried raising the voltages a little. That didn't work so I brought both CPU multiplier and voltages all back to their default settings, but that didn't solve the problem either. The problem still occurs. -AV scanned the whole system, nothing suspect. -I suspected that it might be a bad power supply so I cracked that open and found the following: I think it might be cap plague, but I'm not sure. It looks more like glue TBH. Could someone help me figure out what might be wrong with this PC? EDIT: Sometimes, after these restarts, I noticed that the GPU fan doesn't spin up, and the single rear case fan that just happens to be connected to the same molex Y-cable as the GFX card doesn't spin up either. Anything to that? EDIT 2: I do use the system quite heavily, but I don't know how that will factor into this. I often play Diablo 3 and EVE Online at the same time, frequently alt-tabbing between the two. I also have Firefox open in the background, sometimes with several tabs, and if I feel like it, I'll mute the in-game sound and open foobar2000 for better music. Could it be that I'm just pushing this thing too hard? EDIT 3: I also noticed something odd. Right before I experience these restarts, my monitor would suffer from very faint lines of static moving across the screen. The monitor is still very much useable, but it is very annoying. Following the restart it disappears, and then would gradually re-appear over the next few days, and then restarts again. I find it to be very odd.

• Is it possible to change an "Unidentified Network" into a "Home" or "Work" network on Windows 7

  - by Rhys

  I have a problem with Windows 7 RC (7100). I frequently use a crossover network cable on WinXP with static IP addresses to connect to various industrial devices (e.g. robots, pumps, valves or even other Windows PCs) that have Ethernet network ports. When I do this on Windows 7, the network connection is classed as an "Unidentified Network" in Networks and Sharing Center and the public firewall profile is enforced by Windows. I do not want to change the public profile and would prefer to use the Home or Work profile instead. For other networks like Home and Work I'm able to click on them and change the classification. This is not available for unidentified networks. My questions are these:- Is there a way to manual override the "Unidentified Network" classification? What tests are performed on the network that fail, therefore classifying it as an "Unidentified Network" By googling (hitting mainly vista issues) it seems that you need to ensure that the default gateway is not 0.0.0.0. I've done this. I've also tried to remove IPv6 but this does not seem possible on Windows 7. UPDATE For those still having problems here is the answer to my issue and the possible reasons why:- Win7 keeps a list of the networks you visit by (I am assuming, but don’t know for sure) the MACID of the device pointed to by the Default Gateway. The default gateway is usually the constant device in a network (i.e. the NAT or router) so can be used to uniquely identify one network from another. The default gateway in the IPv4 properties panel must therefore point to an actual endpoint so windows can then keep track of it. If there is a device at the end of the Default Gateway windows will identify it and track it remembering its settings. The ways you can therefore fool Win7 is to either point the default gateway to your own IP address, or the IP address of the target device you’re communicating with. This will have the side effect of expecting that target device to start routing packets for IP destinations that are outside your subnet. So some applications on Win7 will try to communicate with the internet, these will be passed on to the default gateway (either back you the same IP address or a target device that is not a router) and thus will eventually timeout because neither can route packets. Which you can usually live with. This gets slightly complicated when you mix a this type of connection with a real connection to the internet via WIFI. The wired network card usually has priority when routing because of the “interface metric” so some applications might not connect correctly.
