Cannot browse remote networks even with WINS configured

- by paradroid

As the NetBIOS protocol acts on Layer 2 and so is not routable, In order to enable network browsing of remote networks, WINS has been installed and configured on two domain controllers, both of which are on different networks. The WINS servers seem to be replicating with eachother, and each has 127.0.0.1 set as the Primary WINS Server in each of their LAN interface properties, with nothing entered for Secondary WINS Server. The DC which holds the PDC Emulator FSMO role has the Computer Browser service running and set to Auto start, and it has the WINS/NBT node type network setting at 0x8 (H-node - Hybrid node). Remote network browsing does not work. Is the WINS/NBT node type correct for this scenario? The reason why I think it may not be the right one is because I set the DHCP Server's 046 WINS/NBT node type option to 0x8 as well, after which the DHCP clients started to disappear from the Network folders. When that option is not set, does it default to B-node (Broadcast node)? Or could it be a problem with the WINS servers setup?

Managing an application across multiple servers, or PXE vs cfEngine/Chef/Puppet

- by matt

We have an application that is running on a few (5 or so and will grow) boxes. The hardware is identical in all the machines, and ideally the software would be as well. I have been managing them by hand up until now, and don't want to anymore (static ip addresses, disabling all necessary services, installing required packages...) . Can anyone balance the pros and cons of the following options, or suggest something more intelligent? 1: Individually install centos on all the boxes and manage the configs with chef/cfengine/puppet. This would be good, as I have wanted an excuse to learn to use one of applications, but I don't know if this is actually the best solution. 2: Make one box perfect and image it. Serve the image over PXE and whenever I want to make modifications, I can just reboot the boxes from a new image. How do cluster guys normally handle things like having mac addresses in the /etc/sysconfig/network-scripts/ifcfg* files? We use infiniband as well, and it also refuses to start if the hwaddr is wrong. Can these be correctly generated at boot? I'm leaning towards the PXE solution, but I think monitoring with munin or nagios will be a little more complicated with this. Anyone have experience with this type of problem? All the servers have SSDs in them and are fast and powerful. Thanks, matt.

Why can I view my site over a 3G connection but not through my wifi?

- by Jonathan

So, I am sitting in my office with four computers on the same network and internet connection. Two of the computers can visit this particular website. Two of the computer get a message "Google Chrome could not find". I have tried FF and IE also with the same problem. I can view the site 90% of the time on two of the working computers although the site seems slow and sometimes I also get the same errors as the other two computers. I have flushed the DNS, reset the router, tested the site on other peoples computers with success. Is this likely to be a site issue, an ISP issue, a hosting issue? Any advice is greatly appreciated.

Router's ssid changes from infrastructure to ad-hoc

- by waldo

For a period of time the router's ssid is shown (on various computers) as a normal infrastructure network - computers connect fine and everything works however after a few minutes / hours all computers see the same ssid as an ad-hoc network (not infrastructure). At this point a computer that was already connected continues to work - a computer that isn't cannot connect. Rebooting the router temporarily restores the visibility of the correct infrastructure ssid. Is something interfering? Connecting computers: macbook (2009), iphone 3g, windows vista desktop, windows xp desktop. Details: - D-Link DSL-2740B router set to WPA2-PSK (Personal) - Enable Wireless : Yes - Wireless Network Name (SSID) : ###### - Country : Australia - Wireless Channel : 1 - 802.11 Mode : Mixed 802.11n, 802.11g and 802.11b - Channel Width : Auto 20/40 MHz - Transmission Rate : Best (automatic) - Hide Wireless Network : No - Group Key Update Interval : 0 (seconds)

How to fake ip at localhost without LoopBack.

- by sexer

How can i fake an ip on my own PC? for example if there were an ip address lets say 201.91.81.71, that Host is somewhere outside of my red and is hosting a webserver. How can set a website on my own PC, and when i go to browser and try to explore 201.91.81.71 it actually explore the website at my own PC? pd: I need it with IP addresses not domain names, since I need to implement it on a non-web service. First guess was installing a LoopBack with 201.191.81.71 as ip, but since some times the subnet works and some other it doesn't isn't a stable solution. Second guess was adding a route to route table : route add 201.91.81.71 mask 255.255.255.255 192.168.1.2 192.168.1.2 is the ip address of my NIC. If i could add this route it would work but windows doesn't let me do so. route add 201.91.81.71 mask 255.255.255.255 127.0.0.1 it doesn't let me set as gateway 127.0.0.1 if 201.91.81.71 isn't set in a NIC, so thats why i set sometimes loopback and this route add is auto, but it needs a subnet mask which doesn't match the ip and cannot set 255.255.255.255, im in real throubles here. can i get some help? thx.

OpenVPN on Tomato and Vista - can't see my network

- by Ian

I followed the instructions here (http://todayguesswhat.blogspot.ca/2011/03/quick-simple-vpn-setup-guide-using.html) to set up a TCP connection to OpenVPN on my Tomato router. Used TCP because the place I usually surf at seems to have the other ports blocked. My Vista laptop is able to connect to the router but I don't appear to be getting an IP address. I'm able to access my router's admin page, but I can't see the network at home. When I browse to Whatsmyip I see my home IP. Here are the results of route print -4 when I'm just connect to the library and when I've fired up the VP connection as well: Library only: =========================================================================== Interface List 22 ...00 ff c4 a0 e7 5c ......

How do I configure a secondary gateway in RHEL5?

Greetings, we have been experiencing a random timeout issue with VPN users connecting to one of our servers which is causing a problem. My network administrator has instructed me to configure a secondary gateway to include the VPN connection.

Is browser based wireless authentication secure?

- by johnnyb10

Our wireless network previously used a preshared WPA/WPA2 key for guest access, which allows them access to the Internet. (Our employee access uses 802.1x authentication). We just had a wireless consultant come in to fix various wireless issues we had; one of the things he wound up doing was changing our guest access to HTML-based instead of the preshared key. So now that guest SSID is open (instead of using WPA) and users are presented with a browser-based login screen before they can get on the Internet. My question is: Is this an acceptable method from a security standpoint? I would assume that having an open network is necessarily a bad idea, but the consultant said that the traffic is still using PEAP, so it's secure. I didn't get a chance to question him further on this because we ran late and a bunch of other things came up. Please let me know what you think about the advantages/disadvantages of using HTML-based wireless authentication as opposed to using a preshared WPA key. Thanks...

Looking for a stepped-up ALIX or Soekris embedded network appliance to load pfSense and/or handle other FOSS-based network roles. Main criteria is a GbE NICs (will be used for core routing/firewalling with managed GbE switches), DDR3 RAM capable, and multi-core/Intel Atom processor, in a 1U rack-mountable case or smaller. Axiomtek has the ideal product but I don't think they have retail channels.

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!

How to configure Windows 2008 R2 server for LAN and wireless internet connections

- by Alchemical

For special testing purposes, we need a Windows server to allow the following: A team member can log in remotely to the server. When remotely logged in, they can disconnect the wireless connection, perform a few tests, and then reconnect the wireless connection. In general, the LAN connection would just be used for the remote login, the wireless connection would be used for performing tests including using a web browser to test certain web sites, etc. How can we successfully configure the server to support 2 network connections like this? (A regular LAN connection + a wireless connection). And also make sure that the tests we perform using the browser utilize the wireless connection for the outgoing internet activity.

Software for managing a gamenet

I need a software for managing gamenet (Gamenet is like a cybercafe except people play games in gamenet instead of surfing the web!) The software should have this basic features: Accounting features (defining users, assigning a usage time to them, etc) Denying access to regular windows features (windows explorer, creating/editing/deleting files) Showing a list of available games to users to run. Creating login report I've tested a software named GamePort but it has some bugs and shortcomings.

3 Servers, 2 Work Fine, One Has Network Issues

- by ScaleOvenStove

i have 3 servers, all relatively the same hardware/config, etc. I run some data pulls on all 3, and on 2 of them, they have 1 nic, and they work fine. On the other , there are 2 nics, and unless they are both plugged in or teamed, the processes time out. Any ideas on why this would be? It doesn't make sense to me, as the other two work fine with 1 nic and don't time out when running the same processes.

LXC container can only access host via bridge

- by vitaut

I have an LXC container with i686 Ubuntu 12.04 running on a x86_64 Ubuntu 12.04 host. I've set up a bridge using instructions here. However the ping from the container only goes through to the host and not to other machines on the local network. Similarly only the host and not the other machines see the container OS. The host's /etc/network/interfaces file looks as follows: auto lo iface lo inet loopback iface eth0 inet manual auto br0 iface br0 inet dhcp bridge_ports eth0 bridge_fd 0 bridge_maxwait 0 The container's /etc/network/interfaces file looks as follows: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp And here's the relevant part of the container's config: lxc.network.type=veth lxc.network.link=br0 lxc.network.flags=up Any ideas what I'm doing wrong?

We currently use a free SSL-FTP client called Move-It-Freely to transmit data from a custom data entry program at over forty facilities scattered around the state to our central server. Under XP, it works flawlessly. Some facilities have upgraded to Windows 7. On these machines, uploads (transfers to us) work, downloads (transfers from us to them) fail. Replacing the Windows 7 machine with an XP machine solves the problem. We have also verified that the network firewall settings have not changed. This problem persists even if Windows firewall is not running. We were able to remote into one of the Windows 7 machines to verify that the Windows firewall was indeed turned off. We cannot replicate the problem on our own Windows 7 machines, and are at a loss of how to fix this feature for our customers. The data contain health-related information, and needs to be encrypted (hence SSL-FTP.) Despite hours spent on Google, we cannot find a solution.

Apache access.log interpretation

- by Pantelis Sopasakis

In the log file of apache (access.log) I find log entries like the following: 10.20.30.40 - - [18/Mar/2011:02:12:44 +0200] "GET /index.php HTTP/1.1" 404 505 "-" "Opera/9.80 (Windows NT 6.1; U; en) Presto/2.7.62 Version/11.01" Whose meaning is clear: The client with IP 10.20.30.40 applied a GET HTTP method on /index.php (that is to say http://mysite.org/index.php) receiving a status code 404 using Opera as client/browser. What I don't understand is entries like the following: 174.34.231.19 - - [18/Mar/2011:02:24:56 +0200] "GET http://www.siasatema.com HTTP/1.1" 200 469 "-" "Python-urllib/2.4" So here what I see is that someone (client with IP 174.34.231.19) accessed http://www.siasatema.com and got a 200 HTTP status code(?). It doesn't make sense to me... the only interpretation I can think of is that my apache server acts like proxy! Here are some other requests that don't have my site as destination... 187.35.50.61 - - [18/Mar/2011:01:28:20 +0200] "POST http://72.26.198.222:80/log/normal/ HTTP/1.0" 404 491 "-" "Octoshape-sua/1010120" 87.117.203.177 - - [18/Mar/2011:01:29:59 +0200] "CONNECT 64.12.244.203:80 HTTP/1.0" 405 556 "-" "-" 87.117.203.177 - - [18/Mar/2011:01:29:59 +0200] "open 64.12.244.203 80" 400 506 "-" "-" 87.117.203.177 - - [18/Mar/2011:01:30:04 +0200] "telnet 64.12.244.203 80" 400 506 "-" "-" 87.117.203.177 - - [18/Mar/2011:01:30:09 +0200] "64.12.244.203 80" 400 301 "-" "-" I believe that all these are related to some kind of attack or abuse of the server. Could someone explain to may what is going on and how to cope with this situation? Update 1: I disabled mod_proxy to make sure that I don't have an open proxy: # a2dismod proxy Where from I got the message: Module proxy already disabled I made sure that there is no file proxy.conf under $APACHE/mods-enabled. Finally, I set on my browser (Mozzila) my IP as a proxy and tried to access http://google.com. I was not redirected to google.com but instead my web page appeared. The same happened with trying to access http://a.b (!). So my server does not really work as a proxy since it does not forward the requests... But I think it would be better if somehow I could configure it to return a status code 403. Here is my apache configuration file: <VirtualHost *:80> ServerName mysite.org ServerAdmin webmaster@localhost DocumentRoot /var/www/ <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log LogLevel warn CustomLog /var/log/apache2/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 </Directory> </VirtualHost> Update 2: Using a block, I restrict the use of other methods than GET and POST... <Limit POST PUT CONNECT HEAD OPTIONS DELETE PATCH PROPFIND PROPPATCH MKCOL COPY MOVE LOCK UNLOCK> Order deny,allow Deny from all </Limit> <LimitExcept GET> Order deny,allow Deny from all </LimitExcept> Now methods other that GET are forbidden (403). My only question now is whether there is some trick to boot those how try to use my server as a proxy out...

Offline Files (CSC) on Windows RT

- by Aeyoun

Windows RT does not have the Offline Files service. The Sync Center is also gone. Can it be enabled somehow? or can anyone recommend a replacement? My options are very limited on Windows 8.1 RT. The only thing it seems Microsoft is offering is something called Work Folders. These are only supported in Windows 8.1. I really want a more generic solution so that I can access files on OS X and Linux (like a samba share).

Encrypting traffic on remote end of SSH tunnel

- by Aaron

Using an example of someone connecting to a VPS, an SSH tunnel will encrypt any traffic coming from the user to the VPS. Once it reaches the VPS network, the traffic is not encrypted and is easily sniffable by network administrators on that particular network. (am I understanding all that correctly?) Is there a way to have the traffic encrypted on both ends so that neither side is susceptible to packet sniffing to reveal what kind of data/traffic/protocol is being transmitted?

Open ports in Windows 7, firewall, public network, port 445

- by chris

I selected "public network" in Windows 7. Windows is listening on TCP port 445: TCP 0.0.0.0:445 WIN7TEST:0 ABHÖREN The corresponding incoming firewall rule isn't activated (4th column): When I choose "workplace network" the SMB incoming port 445 rule is still disabled in the advanced windows firewall configuration. I thought "public network" / "workplace network" and so on is influencing the windows firewall rules!? Where's the difference between workplace and public network then? http://www.abload.de/image.php?img=winfire2nxku0.png

How to get Atheros ar242x wireless adapter working under Debian Linux?

- by Mark

Does anybody know how to get the Atheros ar242x wireless adapter working under Debian Linux (5.0.2 and/or 5.0.3)? My Debian live CDs and install CDs both don't like this card at all. Curisouly, it seems to work on other, Debian-based, Linuxes. Is this a free/non-free Driver issue? I know Debian gets mardy about that. Although for what it's worth, the Live CD doesn't seem to detect my wired LAN connection either... Specifically this is on a Samsung R610 laptop (some version of which seem to have an intel wireless adapter - this one definitely doesn't!) I've tried all sorts of things but obviously on a live CD installing software is limited. I've also tinkerering with network config files and kernel modules etc but to no avail.

GNS3 Cannot ping/resolve DNS record

- by Eldad Cohen

I set up an internet lab with GNS3, which has 3 routers, in each node there is a computer directly connected. One of the hosts is a DNS server, Windows 2003 Server. The other one is a Windows XP machine. Ping is good between routers and machines but no ability to ping domain.com record on DNS server 2003. I set a static nat on the router to route all traffic from gateway to the DNS server internal ip address, still no answer for the dns request. Any ideas or thoughts will be most welcome.
