• Trouble in Team Viewer VPN Connection

  - by Sumit Pal

  I have completed initial vpn connection setup. It has connected. I have tested with ping and it is ok. My problem is, when I want to start file transfer in VPN it asks for username & password. So what is the user name? I have tried giving Computer-Name/User-Name. I have found my Computer Name by going to Control Panel/System/ & clicking 'Computer Name' tab & username from user accounts or it is shown when I login in windows account (Please correct me if the above procedure is wrong). But what is the password? I have tried giving the account password but it always give 'The username or password is incorrect.' My Question: How to find the username & password? For Information: a) I have Team Viewer 7 installed in one Windows XP PC & one Windows 8 PC. I like to create a secure connection between these two PCs. b) The two PCs are connected in the same local network via a router. Please ask if you need additional information.

• NTFS 'Owner' missing when accessing hard disk from external USB adapter

  - by trismarck

  I have a hard drive with Windows XP SP3 installed on it. When the drive is connected through the standard SATA connector inside the laptop, everything works as expected. However when I remove the drive from the laptop and connect the drive to the external USB adapter, almost all files / folders lose the 'Owner' field contents. I was wondering why could that be. I've tried two USB adapters and this happens on each. I could take the ownership of all of the files, but this would overwrite the Owner value (the Owner value that is present when the drive is accessed through standard SATA connector in the laptop). //edit: if the hard drive is used through the USB adapter, I can't access most of the files, at least until I take ownership of the files (/folders). This is how it looks like: HDD inside USB adapter: HDD inside laptop: (note the Owner column) //edit: some of the files on the first screenshot have Owner field filled up. That's because I took the ownership of those files / folders to be able to access the files on the hard drive. //edit2: also, if the hard drive is connected through USB adapter and if I've took the ownership of some files by the 'ddd' user, then if i login as a different user (lets say 'eee' user), the owner field is _still_ empty: ddd user: eee user: eee user can't access the 'ddd' folder. Both users have Administrator priviledges.

• A router that supports connecting with 2 different wifi networks

  - by Allan Deamon

  I Have the following setup in one place: We have a small local ISP through wireless. I have a external parabolic antenna, connected to a external usb wifi radio, connected through USB to a desktop old PC. The pc connects do the ISP wiki network, then do a Dial Up (PPPoE) connection through the this wifi setup. This will expand with others mobiles devices to be used. When I need, I take my home wireless router and connect though Ethernet in the PC, which is shares the internet. The problem is that the PC must be always ON and working. I would like to buy a wireless router which could be an AP to the mobile devices, notebooks, etc, as also could connect to the ISP Wifi/PPPoE network. So, this device must: Have one radio with detachable antenna to connect to the external antenna. It must connect as client to a network and then dial up the PPP Have another radio serving as AP (infrastructure) to the local place This can't be very expensive. I found a candidate: ( http://www.tp-link.com/en/products/details/?categoryid=1682&model=TL-WR2543ND ) It have 3 deatachable antennas, working with dual band. Officially, his firmware doesn't support it. My supposition: If internally there is 3 or 2 distinct wlan ports (like wlan0, wlan1), and there is support, i could use a OpenWRT, DD-WRT or Tomato to make this works. It also have 1 USB port, which I cold use to connect my actual USB Wifi card on it instead to the old PC. Another alternative, is a router that can do this out of box, with the original firmware. But I don't think this is a easy thing to find.

• postfix - connection refused from behind NAT

  - by manchine

  When attempting to telnet postfix from a different host in the same LAN through the FQDN (and thus the LAN's public IP), the following error occurs: root@mailer:/var/log# telnet mail.domain.com 25 Trying 1.2.3.4... telnet: Unable to connect to remote host: Connection refused Other services can be reached from the exact same host, however: root@mailer:/var/log# telnet mail.domain.com 22 Trying 1.2.3.4... Connected to mail.domain.com. Escape character is '^]'. SSH-2.0-OpenSSH_6.0p1 Debian-4+deb7u1 To make matters more intriguing, Postfix can be accessed from outside the LAN: nunos-mbp:mailog nzimas$ telnet mail.domain.com 25 Trying 1.2.3.4... Connected to mail.domain.com. Escape character is '^]'. 220 mail.domain.com ESMTP Postfix (Ubuntu) To sum thing up: a) Postfix (running on 10.10.10.4 / mail.domiain.com) refuses connection from a host in the same LAN (10.10.10.2), but only when queried through the FQDN (mail.domain.com) b) mail.domain.com accepts connections to other services (but Postfix) from 10.10.10.2 c) mail.domain.com accepts connections to all services, including Postfix, from the outside world If it were a firewall issue, then I believe it would not be possible to connect to any service from 10.10.10.2 through the FQSN / public IP. It ought to be some missing parameter in Postfix, although I haven't found any clear pointers so far.

• Different external ip addresses from different sites

  - by user630286

  My router is ClearOS 6(Centos 6). In my router, I have two external (internet) network connections from two ISP's. The primary connection is eth2 connected to a cable modem and the second one is ppp0 connected to a dsl modem. I have assigned eth2 as the primary connection (with a high metric value). In fact this is done through clearos's multiwan web interface. I have a test in my Nagios to monitor whether the primary connection. This connection is done based on the result of curl ifconfig.me But it seems that ifconfig.me is always giving the ip address of my secondary connection. I tested it through a browser. Yes ifconfig.me gives the secondary internet's(ppp0) ip address. But whatismyipaddress.[com|org] give my primary ip address (eth2). I checked the default route on the router through ip route list 0/0 which also shows the primary connection (eth2) as the default route. The traceroute www.google.com and traceroute ifconfig.me both seems to trace through the primary connection (eth2). As our secondary internet connection has only got a limited download, I don't want to end up having to pay a large sum at the end of the month. Has somebody got an idea why the ifconfig.me shows my secondary address? What is the best way to ensure that my router(and thus the lan) use the right internet connection.

• Windows Server 2008 - RAID 5 Fails on Reboot

  - by Adam

  Hey, I've got an install of Windows Server 2008 Enterprise. It's running software RAID-5 with five disks. The disks were originally formatted under Windows Server 2003, but came up fine once I installed Windows Server 2008. The issue I'm having is that every time I reboot the server, the RAID comes up with a "Failed Redundancy" - the data stays available. I have 4 disks on a PCI SATA controller, and one of the disks connected to the motherboard's on-board SATA ports. (The other on-board port has the system disk connected.) I was having Disk #4 fail consistently, so I tried swapping the cables on the controller end. I swapped the on-board RAID disk with one on the PCI controller. Same issue now, expect with disk #1. Once the system's up, I can reactivate the RAID, it will resync for a while, then go to "Healthy", and will stay that way for an indefinite amount of time - until I reboot. As soon as I reboot, the disk drops again. I've ruled out disk + cable with the recabling. I don't believe it would be the controller as it seems to work fine most of the time - only failing on reboot, and the other port on the same controller connects the system disk - which is clearly working. I did look in the event log, but didn't see anything particularly relevant (although I didn't know what I was looking for - just looked for anything with a "Warning" or "Error" symbol that looked disk-related :)). I'm not particularly familiar with RAID on Windows, does anyone have any idea why this might be doing this? Any idea how to fix it? Any suggestions appreciated! -- Adam

• Western Digital HDD disappears and reappears in BIOS

  - by tbkn23

  I know many people asked about similar problems, but I have a very specific case where I can't understand what's going on... I have a 3TB Western Digital Caviar Green disk connected in my Desktop, that also has a seagate 1.5TB disk and 2 SSD drives (OCZ and Sandisk). After working fine for quite some time (probably more than a year), suddenly my Caviar Green drive disappeared from windows. I checked the BIOS, and it wasn't there either. I opened my PC, played with the connectors, power, etc, but nothing helped. Even tried switching connectors with those of the 1.5TB disk, and nothing changed, the 1.5TB seagate was there, but the 3TB WD was not. Ok, now for the strange part. I have another desktop at home, so I took out my 3TB drive, connected it there, and it worked fine! I copied the most important files out of it, and then made another attempt in the original desktop. Surprise! It now appeared in the BIOS and worked fine! I even ran the SMART test with the WD tools and it said everything was intact. It doesn't end here. After leaving it overnight in the original desktop, it disappeared again in the morning. I repeated the entire process, connecting it to the second desktop, and there it is again working fine. Now for my question... Whats going on? The disk seems to be appearing on/off in my original Desktop, while other drives there work fine. SMART test says the disk is fine. Any ideas? Is the disk defective and should be replaced? Or maybe there's a problem with the controller in the desktop? I'm using a Gigabyte GA-880GA-UD3H motherboard and tried connecting the drive to both bridges (SATA2 and SATA3 bridges). Thanks EDIT: Power options are set never to turn off hard drives:

• Snow Leopard takes a long time to connect to Windows/Samba server

  - by hood

  We run a very heterogeneous network here: There is some XP, Vista, 7, Leopard, Snow Leopard clients, and Windows 2003 (one remaining legacy app), 2008, and Linux servers. The main file server runs Ubuntu Linux and has been added to the Windows Domain and has been used for many years; SBS 2008 is the PDC (the 2003 and 2008 are on the domain also). In Leopard there were no problems at all authenticating to the file servers. We've upgraded one of the Leopard iMacs to Snow Leopard, though the same problem occurs in a new MBP which came with the newer OS as well as a clean install on another iMac. It does not matter whether connected through wired or wireless. In the Finder when clicking on the server - whether on first boot or after it is connected - it will display "Connecting..." for up to a few minutes before either generally working (if username/password in keychain) or displaying "Connection Failed" - at which time clicking "Connect As" and typing in the username/password will take some more time and eventually work. Sometimes it will display "Connecting..." indefinitely. (I've left it as long as 15 minutes before trying something else) Accessing shares on the the 2003 and SBS servers have the problem (so I don't think it's a Samba server issue). The Server 2008 Standard is connecting instantly at the moment. Accessing the share through an alias/stacks doesn't have this problem. Leopard and Windows clients still have no problem. I've searched Google but hasn't yielded any working result. How do I get rid of this delay?

• How can I redirect/forward all the UDP/TCP traffic on one interface to another interface in OpenWrt

  - by Sina Sou

  I am new to networking and I have a measurement device (D) that periodically sends all its readings over few UDP multicast sockets (with different multicast IP addresses and different port numbers). That device even listens to a TCP socket simultaneously to modify its configuration on port 7234. Since the device has just a Ethernet interface for communication and I want to make it work wireless, I decided to use a very small wireless open-wrt based router that attaches to the device (D) and redirect/forward all the network traffic(Both UDP/TCP) to the router wireless interface. In order to simplify the problem assume that the Device (D) establishes following sockets (at the same time) UM_SOCK1: UDP mcast socket on 239.1.2.3 port# 50620 UM_SOCK2: UDP mcast socket on 239.1.2.4 port# 50640 TC_SOCK3: TCP DHCP/STATIC ip address 192.168.1.200 port 7234 And (D) is connected to Open-Wrt router (R) via interface en01 (Ethernet) the router has it own wireless interface on (wlan0) I want all the traffic from interface pass through wlan01 and vice versa (bi-directional) en01 <---- wlan01 What would be the minimum iptables or ... commands that I need to make this possible? Even I am wondering if traffic directing can be made easier like if the direction is not going to be based on IP addresses(not desired if the device is connected via DHCP) I would rather redirection to be Interface(en0) based or on MAC address (The best solution since my device has unique MAC address)? Thanks

• How to send from my Z88 to my PC

  - by Bevan

  I've got a Cambridge Z88 that I want to get working with my PC. Around 6 years ago - in 2004 - I made heavy use of my Z88 to do a whole bunch of writing on the train while commuting to and from work. The Z88 is solid state, lightweight and has a full size silent keyboard, so it works very well as a writing instrument. I still have the serial cable I soldered up back then and used successfully in 2004. It has these connections: Z88 9 pin ----- ------- 2 TxD ------> RxD 2 3 RxD <------ TxD 3 7 GND <-----> GND 5 4 RTS ------> CTS 8 5 CTS <-+ RTS 7 8 DCD <-+---- DTR 4 9 DTR ----+-> DCD 1 +-> DSR 6 Unfortunately, I haven't been able to find my notes from 2004 that describe how I got it to work back then. I've spent several hours trying to Google a result, but to no avail. I'm pretty sure the cable is fine - after all, it's what I used successfully six years ago, and I've checked it out with a multimeter - so I'm focusing on the PC end of things, which is where I'd like some assistance. Q1: In my recent attempts, I've been using both Hyperterminal (as built into Windows XP) and the command line (copy com2: con:), but with no success. What's a good (better!) serial communications application to use? Is there one that allows me to see as deep as the signalling that's occurring on the wire? Q2: If you have a Z88 that works correctly with your PC, what software do you use on the PC end, and what's the pinout of your cable? I'm pretty sure that the Z88 itself is working properly: When using the built in Import/Export tool to send a file, I see different behaviour when my serial cable is connected compared to disconnected. When disconnected, the transmission appears to work, with a progress meter counting up and then finishing; when connected, nothing happens 'cept a timeout if I wait long enough.

• Virtual IPv6 Network between VirtualBox VMs

  - by Ben

  I'm trying to create a virtual IPv6 network as a test environment. I have 5 VirtualBox VMs (Ubuntu Server) with network adapters using host-only networking. You can imagine them being connected in series and every machine connects 2 subnets. I want to ping the last machine from the first one: On: 2001:db8:aaaa::100 I want to ping 2001:db8:dddd::101 (Note: there is no cccc network in between) Only static configuration and routes are used: /etc/network/interfaces auto eth0 iface eth0 inet6 static address 2001:db8:aaaa::100 netmask 64 /etc/network/interfaces auto eth0 iface eth0 inet6 static address 2001:db8:aaaa::101 netmask 64 auto eth1 iface eth1 inet6 static address 2001:db8:bbbb::100 netmask 64 up ip -6 route add 2001:db8:dddd::/64 via 2001:db8:bbbb::101 dev eth1 down ip -6 route del 2001:db8:dddd::/64 via 2001:db8:bbbb::101 dev eth1 I thought there might be some automatic route discovery going on. Anyway, ping6 2001:db8:dddd::100 will not work from aaaa::100 When I add the route: ip -6 route add 2001:db8:dddd::/64 via 2001:db8:aaaa::101 it will work. But the next interface in the same network dddd::101 is not reachable. How could that be? There is a machine with an interface bbbb::101 and another dddd::100 and I can ping the latter one, but the machine connected to it, dddd::101 not?? I also have also turned on forwarding. Any ideas?

• How to configure network on Windows Server 2008

  - by Gokhan Ozturk

  I have a IBM x3400 Server Machine with Windows Server 2008 R2 installed on it. But, since I am not expert on networking I have some problems. These roles installed on my server: Active Directory DNS File Sharing Hyper-V ISS VPN There is two network card on them. I configured them like this: Local Connection 1: 192.168.30.3 255.255.255.0 192.168.30.2 127.0.0.1 Local Connection 2: 192.168.30.101 255.255.255.0 192.168.30.6 127.0.0.1 My problem is, when I use this Ip gateways, It is sharing internet to all computers. This is not I want. I want to use Local Connection 1 for internal network. I am giving all computers gateway and DNS IP as 192.168.30.3 The Local Connection 2 is for Hyper-V and VPN connections. 192.168.30.2 and 192.168.30.6 are my modem's gateways. I am using 192.168.30.6 external IP for VPN connections. There is two 24 port switches. There is a connection between them and this two ethernet card connected directly to them. And modems are connected to switches as well (Morems are not near the server. They are somewhere in the building). I disabled network Bridge and removed all ethernet cards from it. With this configuration, all computers can ping my server's IP (192.168.30.3) but on server I cannot ping any clients (Request timeout). What is the best way to configure my network? Thank you.

• System and Router configuration for setting up a home firewall based on Zentyal

  - by Ako

  I am not much of a system administrator, so please be patient if this looks too simple for you. I have a several computers at home, and all of them connect using an ADSL modem/router (and Wireless AP). I have been attacked several times (mainly from Russia and Ukraine), so I thought I should have some kind of firewall, besides the ESET firewall on my Windows 7. So now I have these (new) configuration: I have a small ADSL modem (Zyxel brand) which has only one Ethernet port. This modem is used to connect to internet and is configured in NAT mode. The interface has is configured with IP address 192.168.1.1. I have an old PC and I have installed zentyal on it. It has two Ethernet ports, eth0 and eth1. Eth0 is connected to the Zyxel modem with IP 192.168.1.2 and is checked as the WAN interface (external). I have another ADSL modem which is also a router with 4 Ethernet ports and Wireless AP. One of the Ethernet ports is connected to eth1 on Zentyal box. The Ethernet port's IP is 192.168.2.1 and Zentyal's eth1 is 192.168.2.2. Now, I want to enable other computers to connect to internet through the router both using Wireless and Ethernet. The problem is that I don't know how to configure the router so it routes connections to the Zentyal box. Does anyone have any clue? Again I am sorry if this looks stupid. Thanks.

• Samba share will not connect (was working yesterday)

  - by David Gard

  I have a CentOS websver with a Samba share set up (\\webserver\websites). I was connected to this share just yesterday without issue, but today my Windows 8 PC will not connect to it. I've also tried making a connection from Windows 7 and Windows XP, all without success. I initially tried restarting my computer, but that did not work. I then tried restarting the Samba service on the webserver (service smb restart), and when that failed I restarted the webserver. All of that was to no avail, and I still cannot connect to the share. The webserver is contactable from my PC (and the others I tried), as the websites it hosts work fine and I'm able to Putty to the server. When connected to the webserver, I can see that Samba is running by using service smb status - service smb status smbd (pid 4685) is running... nmbd (pid 4688) is running... Can anyone please help me to get this share working? Here is my full Samba config (/etc/samba/smb.conf) - [global] workgroup = MYGROUP server string = Samba Server %v log file = /var/log/samba/log.%m max log size = 50 security = user encrypt passwords = yes socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 local master = no [websites] comment = Websites browseable = yes writable = yes path=/var/www/html/ valid users = dgard

• External HDD incorrectly detected as internal - how change to enable hot swap/eject?

  - by Sam

  I have win 7 x64 Home Prem. The HDD is a seagate barracuda, 7200.7 ST3120827AS. 3.5", Serial: 3ms006n6, Firmware: 3.42 (no further updates) NexStar CX External case (drivers installed). I have three drives: WD320 with OS installed WD750 data storage (internal) seagate 120 (external) - connected via esata board connected to sata on motherboard (MSI p43 neo) Tried uninstalling HDD in device manager to no effect. Also the internal WD750 is detected as an external drive and win taskbar icon allows for it to be ejected (unlike the seagate). All drives are configured - Online, Simple, Basic, NTFS, Active, Primary Partition (except c drive). The seagate was previously used as a primary disk with XP operating system so I deleted the volume and created/reformatted (not quick). HDD is no longer "Active". But did not fix problem. Background Originally, I installed win 7 with the bios set to IDE and forgot to install the chipset drivers. Then I changed win 7 to install the AHCI drivers, changed the bios to AHCI and rebooted. Win 7 loaded drivers but WD HDD gave problems/crashed. I installed chipset drivers and latest intell storage matrix software thingie (in safe mode). Everything worked fine after that except for the problem of not corrrectly detecting the external drive] I have noticed that under the driver properties (and similarly in the registry) the two drives are configured differently (e.g. in driver details property capabilities for the WD the value is set to 0000006, CM_DEVCAP_REMOVABLE & EJECTSUPPORTED - whereas the seagate shows 0000080 & CM_DEVCAP_SURPRISEREMOVALOK). Any easy way to configure things? I tried physically swapping the sata connections on the mainboard without success So far I have found that a solution to my problem might be to perform some reg changes: How do I remove the option to eject SATA drives from the Windows 7 tray icon?

• Freshly installed dd-wrt on dir-300 and no internet. What to do?

  - by Erik B

  With the d-link firmware I just connected the router and it worked, as is expected when using DHCP, but with dd-wrt I have no internet access. It is configured with DHCP, and dd-wrt's wan status page reports that it is connected and that it has an ip address. Yet it is impossible to reach the internet. If I disconnect the router and plugs the cable directly into my computer I get internet access, so it's obviously the dd-wrt software that isn't doing its job. However, I have no previous experience with the dd-wrt software and have no clue what to look for. I thought it would just work. By the way, the power led is orange, the internet led is off, and wireless+lan1 is green. They all used to be green with the d-link firmware. Not sure if it's relevant, but now you know. Does anyone have any idea what I should do to get internet access (besides reinstalling d-link's firmware)? EDIT: It's a version B1. I read that it is very different from the A1 version, so I thought it may be relevant.

• Limited connections to Ubuntu 12.04 server

  - by Luis M. Valenzuela

  I'm having a weird problem with my server. The server is inside my network, connected to a 3com switch which is connected to the router that handles the internet connection. The main purpose of the server is to host a php application. What's happening is that user 1 to 15 in the private network have no problems connecting to the server, when user 16 tries to connect a time out comes out and is unable to connect to the server. It's not just to the php application, but to any service from the server. When the 15 users are using the application, the server doesn't even answer to ping. I haven't set any special limit in Apache's ini file or MySql and the firewall is being turned off because the server is only to give service to the internal network. Is there a parameter in any of the network's card conf. files that might me causing this ? Or should I suspect from the router's or switches configuration ? UPDATE. Tomorrow, I'm gonna do some test on the server modifying two kernel params in : /etc/sysctl.conf The settings are: net.core.somaxconn which has the limit on simultaneous network connections to the server and kernel.shmmax which controls the amount of memory the system can use for managing connections.

• Computer does not boot, often

  - by tam

  I've ran into a issue with my computer that it does no longer reach POST, but simply powers on for a fraction of a second and powers off. But this is not always, some times it boots just normally and it works as it should, no issues with not enough power or anything. But as soon as I turn it of, I can not turn it back on, but then again at some random point it just powers up again, and resumes normal operation. If I disconnect the 8pin ATX connector from the motherboard, it powers up, fans and disks spinning normally until I power it off again. So this problem only happens when ATX is connected, which seems odd, I normally always saw this kind of an error if ATX was not connected, but here it's the exact opposite. It also does not emit any sound on the buzzer, except the normal beep, when it powers up normally. I have already tried: Remove graphics card Remove one and/or all RAM sticks Disconnect everything non-essential, even hard drives Clear CMOS I have not yet tried to remove all components and tried to boot everything outside of the case, because I did not have the time to disassemble and bleed the water loop. However, I can confirm that nothing is stuck underneath the motherboard, not is any of those brass raisers touching the board where it should not. Specs: Gigabyte GA-970A-UD3 AMD FX6300 ATI HD7850 I think this should be enough for this issue.

• lenovo x1 carbon windows 8 frequent wifi disconnect issue

  - by hIpPy

  I'm having frequent wifi disconnects on my Lenovo X1 Carbon Touch laptop. I got this laptop 2 months back and it has been happening ever since about 3-5 times a day and 10 times a week on average. I've Frontier Fios internet. Power connected or not does not matter. Once I get disconnected, I try below to connect again in that order: turn Airplane mode on and off, troubleshoot network problems windows troubleshooter), restart the laptop I'd find that the WiFi adapter would get disabled and sometimes windows troubleshooting would help but more than often I'd end up restarting the laptop. A week back, I upgraded my wifi network adapter drivers (now Intel, version 15.5.6.48, 10/3/2012). I still get disconnected frequently but turning Airplane mode on and off gets me connected again. So the driver update did help. Windows 8 is updated. None of the other devices (nexus, iphone phones, nexus7, ipad tablets) would have wifi issues when my laptop would get disconnected. config: Intel(R) Centrino(R) Advanced-N 6205 (WiFi network adapter) Microsoft Windows 8 Pro Microsoft Windows [Version 6.2.9200] x64-based PC LENOVO System Model: 3443CTO X1 Carbon Touch I recently noticed this log message When I got disconnected in event viewer: Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x[XXXXXXXXXXXX]. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server. Any idea?

• IPv6 works only after ping to routing box

  - by Ficik

  Situation: There is ipv4 only router in network and every computer is connected to it (wifi or cable). Server with ipv4 and ipv6 is connected to this router as well. Server has configured tunnelbrokers 6to4 tunnel and radvd. Clients in network has right prefix and can ping each other. But they can't ping to internet until they ping Server (the one with tunnel). I found somewhere that it's icmp problem, but I couldn't find solution. Is it problem that there is ipv4 only router? server and client runs linux router runs dd-wrt without ipv6 support :( Ping try: standa@standa-laptop:~$ ping6 ipv6.google.com PING ipv6.google.com(2a00:1450:8007::69) 56 data bytes ^C --- ipv6.google.com ping statistics --- 29 packets transmitted, 0 received, 100% packet loss, time 28223ms standa@standa-laptop:~$ ping6 2001:470:XXXX:XXXX:21c:c0ff:fe2b:6478 PING 2001:470:XXXX:XXXX:21c:c0ff:fe2b:6478(2001:470:XXXX:XXXX:21c:c0ff:fe2b:6478) 56 data bytes 64 bytes from 2001:470:XXXX:XXXX:21c:c0ff:fe2b:6478: icmp_seq=1 ttl=64 time=3.55 ms 64 bytes from 2001:470:XXXX:XXXX:21c:c0ff:fe2b:6478: icmp_seq=2 ttl=64 time=0.311 ms 64 bytes from 2001:470:XXXX:XXXX:21c:c0ff:fe2b:6478: icmp_seq=3 ttl=64 time=0.269 ms 64 bytes from 2001:470:XXXX:XXXX:21c:c0ff:fe2b:6478: icmp_seq=4 ttl=64 time=0.292 ms ^C --- 2001:470:XXXX:XXXX:21c:c0ff:fe2b:6478 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 0.269/1.107/3.559/1.415 ms standa@standa-laptop:~$ ping6 ipv6.google.com PING ipv6.google.com(2a00:1450:8007::69) 56 data bytes 64 bytes from 2a00:1450:8007::69: icmp_seq=1 ttl=57 time=20.7 ms 64 bytes from 2a00:1450:8007::69: icmp_seq=2 ttl=57 time=20.2 ms 64 bytes from 2a00:1450:8007::69: icmp_seq=3 ttl=57 time=23.4 ms ^C --- ipv6.google.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2001ms rtt min/avg/max/mdev = 20.267/21.479/23.413/1.392 ms

• Server 2008 RAID 5 Write Speeds

  - by Solipsism

  I recently configured a RAID 5 partition in Server 2008 with 4 RAID 5 disks. These disks are connected through a SATA expansion card that uses PCIe. This morning, I checked and they had finally finished synchronizing, and so I tried to do some speed tests. Copying off the disks started pretty much fine - speeds began at 125MB/s, then trailed down to about 70MB/s, which I found odd but not worrying. Writing TO the disks however is a completely different story. I attempted to copy some of my VM host ISOs onto the disks (~2-4 GB apiece) and this resulted in speeds of approximately 10MB/s. I tried copying both from a local disk (connected directly to the motherboard) and from another server ththe gigabit network and results were the same. I checked the performance monitor while transferring the files and the only thing that stuck out was that my memory hard faults shot up to 6,000 per minute (spiking around 200/s) by explorer.exe. The system is running 2GB of DDR667 ECC RAM and a quad-core 2.3GHz opteron. Is there anything I can do to fix this performance issue (buy more RAM? move the drives to a faster box?, etc) or am I just screwed so long as I stick to windows.

• DVI output only working on Windows, not during booting or on Linux

  - by Mononofu

  So yesterday I booted my laptop up and the external monitor I have it connected to just stayed black. At first, I thought the problem would go away when Ubuntu was loaded, but it didn't. I tried to reboot a few times, to no avail. Then I decided to give Windows 7 a try, and suddenly (at the login-screen), my external monitor turned on and worked like normal. I have connected the monitor via DVI, and this only seems to work with Windows now. I don't even get a signal in my BIOS! Mind you, everything was working fine before that, and I didn't change a single thing. I then tried to connect the monitor via VGA (from my DVI jack, which can output VGA using an adaptor), and it worked again. However, 1920x1200 using VGA looks like crap - black print on white background is basically illegible. Do you have any ideas how to fix this peculiar problem? I only use windows for gaming, so it's no real help that it still works normally. Please also excuse any spelling mistakes, I am practically typing this blindly. Edit: I only have one graphics card in my laptop, and I can't select anything related to that in my BIOS. In fact, I can pretty much do almost nothing there. My laptop is a Nexoc Osiris E703, graphics gard is a GeForce Go 7900 GTX. As I mentioned before, DVI output during booting and on Ubuntu was working fine for years before yesterday!

• Same native and tagged vlan possible on Redhat?

  - by Chris Phillips

  Hi guys and gals, I'm looking at implementing a systems using a number of tagged and a native vlan connected to a server over a a/p bonded interface. The untagged vlan is for physical machine access, the tagged vlans are connected to bridges and then to QEMU VM's inside the machine. Hopefully this plan is fine, but I'm trying to implement a crippled version of this in a dev environment due to a lack of underlying network config in this location where I just have the same single vlan delivered to the machine on a tag AND plain. I'm nto clear if this is going to work (and that I should just be confident that it will work using different vlans) as I'm seeing odd things like a vm is arping out over the vlan out to the core switch, but the arp reply is coming back on the untagged interface. Now an ARP reply is unicast right? So it's a deliberate thing to send the ARP response on the untagged interface, and not a case that a broadcast response isn't being passed on the tagged side... i.e. there's some underlying logic pushing it that way. Something about the MACs somehow? This is on a CentOS 5.5 machine, vlan's from vconfig. (I've seen reference to the Linux mac-vlan project work, but that's not available here by default.) so 1) Should having the SAME vlan tagged and untagged work? 2) Will different tagged vlans to the untagged interface work nice and easily?

• SSH not working through Double NAT

  - by d_inevitable

  I am trying to setup port forwarding for ssh through 2 NATs The first Router translates my internet IP to my outer network (10.1.7.0). In the outer network there's a second Router that does NAT to my inner network (192.168.1.0). The target server is connected to both, the outer network and the inner network. I cannot change the port forwarding options for outer router. It is currently configured to forward the SSH and HTTP port to the router for the inner network. Internet + | v +-----------------+ +------------------+ | Outer Router | | Inner Router | |-----------------| |------------------| | | SSH HTTP | | +----+ +--------------------->| | | | | | | | | | | | | +-------+---------+ +------+---------+-+ | | | | | | | | | | | | | | +------------------+ | SSH | | | | Server | | | | | |------------------| | | | +-----------> |<-------+ | | | | |HTTP (testing) | +------------------+ | | | +------v------------------+ | | Outer Workstation | +-------------------+ | |-------------------------| | Inner Workstation| | | | |-------------------| | | | | |<----------------+ +-------------------------+ | | +-------------------+ When connecting from a outer workstation to the address of the inner router, then both SSH and HTTP work fine. When connecting from the internet to my public ip with HTTP, the connection works fine as well. However SSH just times out. Most likely because the reply is not routed back properly. I suspect its either because of the SSH itself, or because the server is connected to both, the inner and outer network. Any ideas how I could resolve this issue? The routes on the server are currently: ip route show default via 10.1.7.254 dev eth0 metric 100 10.1.7.0/24 dev eth0 proto kernel scope link src 10.1.7.1 192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.2 Do I have to change this? If so how?

• Uninstalled server 2008 now router won't handle DHCP

  - by john

  My set up is this. server behind router, router has a server and switch connected to it with multiple computers. router used to serve DHCP and DNS, a couple of days ago installed AD, DNS and DHCP on the server, and the server gave out IP's. For various reasons we had to uninstall the domain on our server. I removed AD, DHCP and DNS from the roles and set the router back to serving DHCP and DNS. Now I can't get computers on the network. I reset my router back to factory defaults, and if I plug a computer directly into the router I can get a IP address, but all the computers behind the switch can't get an IP address and can't see the router. All my computers say unidentified network, and if I ping the router it says host is unreachable. On the other hand, my wireless devices are just fine and connect no problem. But for desktops, ipconfig /release doesn't release anything and /renew can't find a server to renew on. My router log shows several FIN scans but they are from innocuous websites (google, netgear) and it shows a couple of smurf attacks but they are all from my external IP. Any ideas? the server isn't even connected to the route right now, and all the computers are set for dynamic IP addresses.. I don't know what else to try? Any help?
