• Internet keeps getting Disconnected & Reconnected

  - by Paul

  I have an Internet connection thru a Phone company which uses DSL modem to connect. For past few weeks my net connection keeps getting disconnected for few seconds & it reconnects automatically. I asked the service provider & they checked & even replaced some wires but of no help. Funny thing is that sometimes there seems to be a rhythm where it disconnects for an average of 13 seconds or so plus or minus few seconds, for hours at a time. I don't know how to attach an image to this post where it shows the pattern of connect & disconnect. I have taken an image using snagit to show the timing pattern. If someone can explain it, I can attach it here. Thanks

• WiFi: Connect to a network with hidden SSID in Windows 7

  - by Dor

  I have Windows 7 with the following station: D-Link DWA-160 Xtreme N Dual Band USB Adapter(rev.A2) (driver version 3.5.0.21). I'm trying to connect to a wireless network that has an hidden SSID with the command: Netsh wlan connect name="myNetworkProfile" The profile is configured to connect even if the network is not broadcasting its name (SSID). Despite that, the command fails promptly every time with the message: The network specified by profile "myNetworkProfile" is not available to connect. Nonetheless, when trying to connect manually using the dialog box (see image below), it successfully connects to the network after about 10 or 15 seconds. Also, Please - no need to elaborate about how useless the hidden SSID feature is.

• Fortigate 200A firewall CPU high resource usage

  - by user119720

  This morning I'm receiving complaints from several end users that saying their whole department network are slow and have intermittent. Therefore I've checked our firewall to see whether if something goes wrong with the device.From my observation in the FortiGate dashboard status, the CPU resources is very high (99 percent). My first assumption is to clear the log since in the alert log the Fortigate log mention that it is already 90% full.Based on my understanding,the log can be cleared by restarting the firewall. After restarting the firewall the network seems okay again but then after several minutes it went up again.The condition still persist until now. Can someone show me where else I can check to fix this issue? I've really appreciate any help that I can get here.Thanks. Edit: diag sys top command

• Why is my connection slow?

  - by Jay R.

  I have a Dell Precision T5400 with a Broadcom 1Gb onboard NIC. For some strange reason, when I access machines on our local network, the best I can get is around 125KB/s download speed. My laptop that has a 10/100Mb NIC onboard usually gets around 300KB/s or better from the same network resource. Both machines are plugged into the same 1Gb switch which connects to our local network wall jack at 100Mb half duplex. There is also a printer plugged into the same switch at 100Mb full. The resource I'm using for the test is a 30MB zip file copied from a jetty webserver that is running as part of a cruisecontrol installation. The cruisecontrol installation is running WindowsXP with full real-time antivirus and Altiris patch management and inventory running. That stuff on its own is eating some of the download speed. I've seen the laptop reach into the multiple MB/s download speed before, but the desktop never seems to get past 125KB/s to 130KB/s. In WindowsXP, before I upgraded the driver in the desktop, it was that slow. In Fedora, it is still slow even though it appears to be using the same driver version as the upgraded Windows driver. The upgraded Windows driver is faster, but still not nearly as fast as the laptop. What gives? Any insight to improve the situation would be appreciated. Could it be that the BroadCom board just isn't that good, or the driver in linux is just not as good as the Windows one?

• How to configure 2 LAN Cards

  - by PatDiazJr

  How do we configure two (2) LAN cards on one computer. One LAN card is connected to the internet via the DSL through a router, configured as DHCP. The other LAN card is to be connected via our office's IP/VPN (for email and other office online processes). I know it could be done, but I do not know how. By the way, the operating system is Windows XP.

• Wireless vs. Wired: which is faster?

  - by studiohack

  I have the option of hooking up my machines to the internet either wirelessly or via ethernet cable (wired). I'm curious as to which is faster; the approximate wireless signal strength (average) is about 60%. My question is, would my internet be faster if I used ethernet, resulting in a stronger connection?

• Accessing local resources over wifi with a BES-connected Blackberry

  - by bshacklett

  I'm trying to get to a local web site on my LAN at 192.168.1.10 with my Blackberry, but I'm getting a message saying the server did not respond. I know that some, if not all, internet traffic on a BES-connected blackberry goes through the BES. This is clear because I can access internal resources on my employers network via the mobile network. Is there any way for me to specify that the device should attempt to route directly over wifi before it tries to connect via the BES server at work?

• D-Link DWA-125 constantly disconnecting in winXP, but works fine on ubuntu..

  - by sil3nt

  Hey there, I'm dual booting winXp and ubuntu 10.10. I'm using a DWA-125 usb adapter to connect to my home wifi connection and I'm having this odd issue. First off, in ubuntu the adapter works fine and I have no trouble at all, but when I boot back in XP I get a dlink connetion wizard and the connection times out after every 2 minutes. It's odd because I can actually load up web pages and use the internet for 2 minutes, and then it would disconnect and the whole thing would repeat. I did a system restore on xp and this stopped the whole connect-disconnect thing but once I booted into ubuntu and came back to xp it started all over again!(?). Any ideas as to how I would go about fixing this?

• nagios wrongly reports packet loss

  - by Alien Life Form

  Lately, on my nagios 3.2.3 install (CentOS5, monitoring ~ 300 hosts, 1150 services) has sdtarted to occasionally report high packet loss on 50-60 hosts at a time. Problem is it's bogus. Manual runs of ping (or its own check_ping binary) finds no fault with any of the affected hosts. The only possible cures I found so far are: run all the checks manually (they will succeed but it may act up again on next check) acknowledge and wait for the problem to go away (may take several ours) I suspect (but have no particular reason other than single rescheduled checks succeeding) that the problem may lay with all the checks being mass scheduled together - in which case introducing some jitter in the scheduling (how?) might help. Or it may be something completely different. Ideas, anyone?

• Routing RFC1918 addresses through dd-wrt via a switch

  - by espenfjo

  I am a bit stuck with an experiment of mine. I have a network looking somewhat like this. | Internet | | ---- |Switch| ---- | | Server w/pub IP | DD-WRT router 192.168.1.1 | | RFC1918 clients 192.168.1.0/24 What I want is for the RFC1918 clients to speak directly with each others. On the server with the public IP I have this route: 192.168.1.0/24 dev eth0 scope link and can see that packets are infact reaching the dd-wrt router for 192.168.1.1, even though if I get no answer. Trying to reach one of the RFC1918 clients from the public IP server will get no result, as the dd-wrt router is not announcing that network on to its external interface (arp who-has 192.168.1.107 tell xxx.xxx.xxx.xxx, but no answer). The router being an WLAN dd-wrt router has of course a load of routes, VLANs and interfaces: xxx.xxx.xxx.1 dev vlan2 scope link 192.168.1.0/24 dev br0 proto kernel scope link src 192.168.1.1 192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.244 84.215.64.0/18 dev vlan2 proto kernel scope link src xxx.xxx.xxx.xxx 169.254.0.0/16 dev br0 proto kernel scope link src 169.254.255.1 127.0.0.0/8 dev lo scope link 0.0.0.0 via xxx.xxx.xxx.1 dev vlan2 xxx.xxx.xxx.xxx being the public IP, and xxx.xxx.xxx.1 being the default route for the public IP. I am not sure where to continue with this. I would recon that I both need routing on the dd-wrt router, as well as some iptables magic? Why do something this complex? Why not ;) Also, do not mind that "Internet" can get RFC1918 traffic, it wont go outside of the walls. EDIT 1: Following the tip from stew I do indeed get the correct ARP flowing. And adding an iptables rule for allowing traffic from that specific public IPd machine I get traffic between the systems! Oddly enough though, the speed I get from Server w/pub IP - RFC1918 clients are the same as if the traffic were routed out onto the Internet and back. Edit 2: Ok, disconnecting the external Internet connection will still give the same, crappy transfer speed. So it has to be something else. Edit 3: Ok, I guess there are other reasons for this crappy speed. Case closed. :)

• Can I connect an external antenna to a range extender?

  - by ercan

  I live in a kind of dormitory and the next access point is 60 meters away from my room. So I bought a range extender (TP-Link WA730RE) and installed it into my room in the same height as the access point. But my problem is still not solved. The reception is slightly better but my connection still gets broken every two minutes. The antenna that comes with this range extender was 4dB. My question is, can I buy an 8dB external antenna (like this one: http://www.amazon.com/TP-Link-TL-ANT2408C-Desktop-Omni-Directional-Antenna/dp/B0034CQSKW/ref=sr_1_14?ie=UTF8&qid=1332074993&sr=8-14) and replace it with the antenna that comes with the range extender? Or is this external antenna only suitable for the "receiver" end of the connection, i.e. the computer?

• Ubuntu 12.04 suddenly cannot connect to WPA2/WPA Personal protected connection. Windows 7 can

  - by d4ryl3

  I have a laptop with Windows 7 and Ubuntu 12.04. I have a Cisco E1200 and when I set it up, it created 2 SSIDs. Let's name them: MyConnection (WPA/WPA2 personal), and MyConnection-Guest (no authentication, guest password entered via web browser). I had no problem connecting to MyConnection before, either in Windows 7 and Ubuntu. But now, I can't access MyConnection on Ubuntu. It just says "connecting..." then disconnects after a while. But I'm able to access the internet (on Ubuntu) when I connect to MyConnection-Guest. MAC filtering is off (even if it's on its MAC address is in the white list). Any idea why I'm unable to connect to MyConnection in Ubuntu? Thanks. Update: My Ubuntu installation can connect to ANY WiFi connection (WPA/WEP/no auth), except for MyConnection.

• Why would one of my servers stop being able to access other servers by FQDN?

  - by Newlyn Erratt

  I have a number of servers on our local network and our debian server has suddenly stopped being able to access the other servers via their FQDN. Initial symptom was inability to login with Active Directory accounts. On further inspection, this machine, porkbelly, was unable to access our other servers (e.g. bacon and albert) via their FQDN. That is, they can ping albert by running ping albert but not by running ping albert.domain.local though when running ping albert it will be expanded to albert.domain.local. The server is still accessible from other servers via both porkbelly and porkbelly.domain.local. Upon examination of hosts information and running hostname its hostname and FQDN are correct. The resolv.conf appears correct. It contains: domain domain.local search domain.local nameserver 192.168.0.xxx (the nameserver) The dns server is also our Windows AD server. I'm not even sure where to go from here or why dns seems to be partially working though I don't have much experience. Where should I go from here? What might be causing this issue where machines are visible via their hostname but not their FQDN?

• Windows Server 2008 Migration - Did I miss something?

  - by DevNULL

  I'm running in to a few complications in my migration process. My main role has been a Linux / Sun administrator for 15 yrs so Windows server 2008 environment is a bit new to me, but understandable. Here's our situation and reason for migrating... We have a group of developers that develop VERY low-level software in Visual C with some inline assembler. All the workstations were separate from each other which cased consistency problems with development libraries, versions, etc... Our goal was to throw them all on to a Windows domain were we can control workstation installations, hot fixes (which can cause enormous problems), software versions, etc... All Development Workstations are running Windows XP x32 (sp3) and x64 (sp2) I running in to user permission problems and I was wondering maybe I missed one, tWO or a handful of things during my deployment. Here is what I have currently done: Installed and Activated Windows Server 2008 Added Roles for DNS and Active Directory Configured DNS with WINS for netbios name usage Added developers to AD and mapped their shared folders to their profile Added roles for IIS7 and configured the developers SVN Installed MySQL Enterprise Edition for development usage Not having a firm understanding of Group Policy I haven't delved deeply in to that realm yet. Problems I'm encountering: 1. When I configure any XP workstations to logon our domain, once a user uses their new AD login, everything goes well, except they have very restrictive permissions. (Eg: If a user opens any existing file, they don't have write access, except in their documents folder.) Since these guys are working on low system level events, they need to r/w all files. All I'm looking to restrict in software installations. Am I correct to assume that I can use WSUS to maintain the domains hot fixes and updates pushed to the workstations? I need to map a centralized shared development drive upon the users login. This is open to EVERYONE. Right now I have the users folders mapped upon login through their AD profile. But how do I map a share if I've already defined one within their profile in AD? Any responses would be very grateful. Do I have to configure and define a group policy for the domain users? Can I use Volume Mirroring to mirror / sync two drives on two separate servers or should I just script a rsync or MS Synctool? The drives simply store nightly system images.

• hardware addressing and configurable addressing scheme

  - by Zia ur Rahman

  basically i want to ask question about configurable addressing scheme for LAN interface hardware. i have read about it from a book, some main points are given by a configurable addressing scheme provides a mechanism that a customer can use to set a physical address.The mechanism can be manual (the switches that must be set when the interface is first installed).or an electronic memory such as an EPROM that can be downloded from the computer(what does this means). Most hardware needs to be configured only once- configuration is usually done when the hardware is first installed. Question:Suppose a network administrator configures the LAN interface hardware (assigns the address) when he installs it. Now later on if he needs to change the physical address of the device can he change it? Or in this addressing scheme the hardware can only be configured once and we can not reconfigure it later on.

• Can't access certain specific IP/domain on Windows 7

  - by jfrobishow

  Been banging my head on the wall for some time now. I have a fresh install of Windows 7 - Ultimate ~x86. Some IPs can't resolve properly, it doesn't matter if I try using Firefox, Chrome or IE I end up with a domain not found (server not found, etc.) I am behind a router, all the other computers aren't affected only this Win 7 machine. It's only certain sites. e.g. xkcd.com, facebook's cdn, google group. Things I have tried: flushdns ipconfig renew Disable IP v6 on the NIC Double checked that the computer was in the right timezone @ the right time. Reinstall the NIC driver. Again 90% of the sites will work but not the major one :P help!!!

• With CentOS 6 and LXC, "ifconfig" is unable to see network interface (but busybox "ifconfig" works fine)

  - by larsks

  I've just started working with LXC under CentOS 6 (via the libvirt adapter). If I create an LXC container, I'm unable to see any network interfaces when using the native system tools: # ifconfig -a # The behavior is very odd; specifying an interface by names yields neither the expected output nor an error message. This is true even for clearly invalid interface names, like this: # ifconfig foo # The ip command exhibits the same behavior. On the other hand, if I use "ifconfig" provided by busybox, everything works as expected: # busybox ifconfig -a eth0 Link encap:Ethernet HWaddr 52:54:00:E0:12:C8 inet6 addr: fe80::5054:ff:fee0:12c8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:268 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:17814 (17.3 KiB) TX bytes:552 (552.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) So...what does busybox know that the native tools don't? The libvirt config for this environment is pretty standard; the network definition looks like this: <interface type='network'> <mac address='52:54:00:e0:12:c8'/> <source network='default'/> <target dev='veth0'/> </interface> The full configuration is here if you think it might help. I'm running: lxc-0.7.2-2.el6.x86_64 kernel-2.6.32-71.29.1.el6.x86_64 EDIT Weirder and weirder...it's a display issue, not a functionality issue. I can see the output of ifconfig if I pipe it into anything, so for example: # ifconfig eth0 | cat eth0 Link encap:Ethernet HWaddr 52:54:00:E0:12:C8 inet addr:192.168.10.10 Bcast:192.168.10.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:fee0:12c8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:573 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:37914 (37.0 KiB) TX bytes:552 (552.0 b) And in fact even when not piping the output, strace shows that ifconfig is in fact writing the output to file descriptor 1 (aka stdout), so it's not clear why no output is actually showing up. This could be either an LXC or a virsh issue, I guess.

• How to make sure Windows PC is reasonably secure?

  - by Coder

  I'm not much of a network and network security expert, but I need to add an existing Windows PC to a network with always on connection. The problem is, I have no idea if the PC is really clean, and, actually, no knowledge to check it. I scanned the PC with Process Explorer to verify if all running processes are signed, ran an AVG scan, but this is where my knowledge ends. IIRC, there can be bad code attached to svchost or something, bad drivers, and so on, but I have no idea how to check all those things. Reformatting the PC is unfeasible as of now. Are there any suggestions on what I could do?

• Crossover cable in addition to normal network connection on servers?

  - by Zero0ne

  I have 2 servers, both with Windows 2003 R2 Each have 2 NIC ports that are 10/100/1000 They are both connected to our LAN + joined to the domain (1 NIC port free on each server) The problem is that our main router is only 10/100 on the ports that these servers are connected to. Since one server is going to host SQL 2005 and the other will be running Altiris NS7, I was hoping that I could use a crossover cable to connect the two directly, thus taking advantage of their 1gbps NIC cards. Is this possible? If so what steps do I need to take to accomplish this? What needs to be done to make sure that when the app server is communicating with the SQL server that it is using the direct link vs traversing the LAN? Thanks a lot!

  I have recently configured 2 firewall (on 2 DELL PowerEdge R210II with ESXI 5.1) with pfsense. We have several LANs and 2 WANs. Everything is running fine but i have a strange behavior: i can access internet from alla LANs but not from the firewall (itself). For example the firewall cannot retrive package information or if i setup a gatway monitor ip (like google 8.8.8.8 ) this fails. These are the screenshots of firewall configuration: http://imgur.com/a/LNuMz#0 ATM i kept firewall rules to minimum to avoid problem or conflicts. Any ideas how to solve the problem?

• Printing on Windows 8 with PDF viewer (Adobe Reader) from network

  - by Bongo

  i have a problem with the Adobe Reader 8, but the problem seems to be equally bad with other pdf viewers. Here is the configuration: My PDF viewer is located on network drive "Z:" which is the network adress \dgs-main\progs. I tried to start the adobe reader from here - \\dgs-main\progs\Adobe\Reader 8.0\Reader\AcroRd32.exe and open the PDF from here - C:\Users\ServiceDesk\AppData\Local\Temp\GeneratedPDF.pdf The problem is as follows, if i open the PDF with a local PDF viewer everything works fine and i can print the document. If i open the PDF with the Network PDF viewer then it opens, but printing is impossible. The error message states: "Unable to start print job. Is printer available?" As mentioned above, it works with a local pdf viewer. In both cases i use the same printer. The Printer is a network printer but even with a local printer it fails. The error occurs only on Windows 8 machines. On windows 7 it works fine. I Hope somebody can tell me what the problem is. Thanks in advance and have a fine day.

• Anyone interested in obtaining a cable list from a visio Diagram? [closed]

  - by Alex

  it's my first post here. Just wondering if anyone had to deal with the following problem - you have to install over say a 100 network elements and servers - cabling is done via contractors, so you need to provide them with an accurate, error-free cable list - your inputs are a set of detailed, port by port, visio diagrams. Prb is to obtain the cable list and get the cabling started while you're busy crafting the switch/routers configs. I coded a Visio plugin, which I plan to release under the GNU license, that returns a cable list from a diagram, and tested it on intermediate size infrastructure, 2K+ cables. It works well. The tool needs a little work to be user friendly, so before getting started, I wanted to know if that was worth the effort. Questions are welcomed, let me know -A PS: the tool is targeted for those who need a port by port description of their network, in the form Source/slot/port/Destination/slot/port.

• How to configure 2nd network card for use in VMWare Workstation?

  - by Timo

  Hi all, I am using VMWare Workstation 6.5, connected to my network with a bridged adapter so that the virtual machine OS (Windows XP) has its own IP adress. This just worked out of the box. Now my host machine (Windows Vista) has an additional network card that is directly connected to another computer using a crossover cable (and fixed IP adress 10.1.1.4, while the "main" network connection is using DHCP with IP in the 192.68.0.* range). How can I use that network connection as well in the virtual machine? Do I need to bridge my 2nd network adapter to some VMnetX adapter? Do I need to add a host virtual adapter? I do not know much about networks, and the VMWare network settings really confuse me :-) Thanks, Timo
