• Mysql Servers for Attendance System

  - by foo

  I'm building an attendance system. There are about 20 places where people will check in and check out using Mifare 1K Card. It will use MySQL as the database. The system will display something like "#ID IN: 800AM" when the first time the user checks in and "#ID OUT: 400PM" when the user checks out. For this to work, all the databases need to be synchronized with each other all the times. For an example, if user A went to location #1 to check in but by the time he wants to return home, the server at location #1 went down, he needs to go to location #2 or the nearest server to check out. The server at location #2 should display '#ID OUT: 400PM" and not "#ID IN: 400PM" since he's already checked in. So, what should I use to ensure this idea will work? My main concern is with the network (other department manages it) which is very unpredictable. It just love to go down anytime it wants to. Update LOL, didn't realize my question is not clear, just noticed it when you guys pointed it out, sorry about that. My real question is, how can I configure my MySQL to be synchronized with each other (20 servers)? MySQL cluster ? (tried reading about it, but I'm not sure if it's the right thing to do) My current setup (first phase): Local database for each server OS: Slackware A main server that keeps track which staff is at which server A web based front end for the user to see their history (which connects to the server based on their records) Main Pros No worries about network problems since it is a local database Main Cons A user can only check in and out at the same server. Databases/Servers are not connected with each others. Have to add the user to each server if the users want to check in at different locations. Which means, if he wants to go to location A, he must be checked out from location A first and then check in at location B. The server at location B didn't know that the user has checked in before at A. By the way, I've already centralized my NTP to a local server. About the network, let's just say, I don't have the authority to make changes so that the network will be better. The network won't effect all 20 servers at once, usually, just a few of them for several times a week. If there are anything else you would like me to answer, please just ask.

• How secure is a subnet?

  - by HorusKol

  I have an unfortunate complication in my network - some users/computers are attached to a completely private and firewalled office network that we administer (10.n.n.x/24 intranet), but others are attached to a subnet provided by a third party (129.n.n.x/25) as they need to access the internet via the third party's proxy. I have previously set up a gateway/router to allow the 10.n.n.x/24 network internet access: # Allow established connections, and those !not! coming from the public interface # eth0 = public interface # eth1 = private interface iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -m state --state NEW ! -i eth0 -j ACCEPT iptables -A FORWARD -i eth0 -o eth1 -m state --state ESTABLISHED,RELATED -j ACCEPT # Allow outgoing connections from the private interface iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT # Masquerade (NAT) iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # Don't forward any other traffic from the public to the private iptables -A FORWARD -i eth0 -o eth1 -j REJECT However, I now need to enable access to users on our 129.n.n.x/25 subnet to some private servers on the 10.n.n.x/24 network. I figured that I could do something like: # Allow established connections, and those !not! coming from the public interface # eth0 = public interface # eth1 = private interface #1 (10.n.n.x/24) # eth2 = private interface #2 (129.n.n.x/25) iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -m state --state NEW ! -i eth0 -j ACCEPT iptables -A FORWARD -i eth0 -o eth1 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A FORWARD -i eth0 -o eth2 -m state --state ESTABLISHED,RELATED -j ACCEPT # Allow outgoing connections from the private interfaces iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT iptables -A FORWARD -i eth2 -o eth0 -j ACCEPT # Allow the two public connections to talk to each other iptables -A FORWARD -i eth1 -o eth2 -j ACCEPT iptables -A FORWARD -i eth2 -o eth1 -j ACCEPT # Masquerade (NAT) iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # Don't forward any other traffic from the public to the private iptables -A FORWARD -i eth0 -o eth1 -j REJECT iptables -A FORWARD -i eth0 -o eth2 -j REJECT My concern is that I know that the computers on our 129.n.n.x/25 subnet can be accessed via a VPN through the larger network operated by the provider - therefore, would it be possible for someone on the provider's supernet (correct term? inverse of subnet?) to be able to access our private 10.n.n.x/24 intranet?

• Port forwarding not working properly

  - by sudo work

  I'm trying to host a small web server from my home network; however, I have not been able to successfully port forward ports to the local server. My current network topology looks like this: Cable Modem/Router - Secondary Wireless Router - Many computers (including server) The modem/router I'm using is a Cisco (Scientific Atlantic) DPC2100, provided by my ISP. The wireless router that I'm using as the central hub to my home network is a Linksys E3000. The computer being used as a server is running Ubuntu 10.04 Server Edition. The main issue is that I can't access the server remotely, using my WAN IP address. I have port forwarded my wireless router; however, I believe that I need to somehow set my modem to bridge mode. As far as I can tell though, this isn't possible. Here are the various IP address settings: DPC2100 WAN: 69.xxx.xxx.xxx Internal IP: 192.168.100.1 Internal Network: 192.168.7.0 E3000 IP Address: 192.168.7.2 Gateway: 192.168.7.1 Internal IP: 192.168.1.1 Internal Network: 192.168.1.0 Server IP Address: 192.168.1.123 Gateway: 192.168.1.1 Now I can do an nmap at various nodes, and here are the results (from the server): nmap localhost: 22,25,53,80,110,139,143,445,631,993,995,3306,5432,8080 open nmap 192.168.7.2: 22,25,80 (filtered),110,139,445 open (ports I have forwarded in the E3000)* nmap 69.xxx.xxx.xxx: 1720 open *For some reason, I can SSH into the server at 192.168.7.2, but not view the website. Here are also some other settings: /etc/hosts/ 127.0.0.1 localhost 127.0.1.1 servername ::1 localhost ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters /etc/apache2/sites-available/default snippet <VirtualHost *:80> DocumentRoot /srv/www/ <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> ... </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> ... </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/"> ... </Directory> </VirtualHost> Let me know if you need any other information; some stuff probably slipped my mind.

• Enterprise IPv6 Migration - End of proxypac ? Start of Point-to-Point ? +10K users

  - by Yohann

  Let's start with a diagram : We can see a "typical" IPv4 company network with : An Internet acces through a proxy An "Others companys" access through an dedicated proxy A direct access to local resources All computers have a proxy.pac file that indicates which proxy to use or whether to connect directly. Computers have access to just a local DNS (no name resolution for google.com for example.) By the way ... The company does not respect the RFC1918 internally and uses public addresses! (historical reason). The use of internet proxy explicitly makes it possible to not to have problem. What if we would migrate to IPv6? Step 1 : IPv6 internet access Internet access in IPv6 is easy. Indeed, just connect the proxy in Internet IPv4 and IPv6. There is nothing to do in internal network : Step 2 : IPv6 AND IPv4 in internal network And why not full IPv6 network directly? Because there is always the old servers that are not compatible IPv6 .. Option 1 : Same architecture as in IPv4 with a proxy pac This is probably the easiest solution. But is this the best? I think the transition to IPv6 is an opportunity not to bother with this proxy pac! Option 2 : New architecture with transparent proxy, whithout proxypac, recursive DNS Oh yes! In this new architecture, we have: Explicit Internet Proxy becomes a Transparent Internet Proxy Local DNS becomes a Normal Recursive DNS + authorative for local domains No proxypac Explicit Company Proxy becomes a Transparent Company Proxy Routing Internal Routers reditect IP of appx.ext.example.com to Company Proxy. The default gateway is the Transparent Internet proxy. Questions What do you think of this architecture IPv6? This architecture will reveal the IP addresses of our internal network but it is protected by firewalls. Is this a real big problem? Should we keep the explicit use of a proxy? -How would you make for this migration scenario? -And you, how do you do in your company? Thanks! Feel free to edit my post to make it better.

• Laptops on Windows Domain sometimes have problems accessing internet when off-site

  - by FSUScoot

  Hi all-- We've had this problem for a long time. When users travel, sometimes they can't get internet access from a wired or wireless connection. Here are a couple examples: 1) A user goes to a hotel and tries to access the wireless in their room. They can connect to the access point. They open a web browser and they can't get re-directed to the hotel's login page. Because they can't log in, there's no internet access. 2) A user goes to another laboratory/university and tries to access the wired network. They connect, link is fine, PC gets IP from DHCP but no internet access. There's no login page to be re-directed to. It should just "work". What I've found is that it's a DNS issue. Because the computer is on a Windows Domain, it seems it MUST use our DNS servers. Even if you connect to an outside network and do an ipconfig /all, it looks like everything is ok. It'll even show their DNS servers listed in the config. The computer just won't use the other network's DNS server. I found a reg key that keeps our DNS servers listed and it seems that they take priority every time: HKLM\SOFTWARE\Policies\Microsoft\Windows NT\DNSClient All the values under that key are for our AD domain. NameServer and Searchlist never change. What I've found is if the user edits the NameServer string and puts the DNS server of the network they're on, everything works just fine. They get re-directed to the hotel's correct login page or their internet access starts working. It's only a problem if the network they're on blocks outside DNS or a hotel that uses an internal name in their front page redirection that only their DNS server knows about, i.e., not public. If the re-direct page starts with an IP, like 10.10.10.10, it'll work just fine. Obviously this isn't a fix for everyone. Most of my users are pretty knowledgeable so it’s easy for me to walk them through or send them a .reg file that they can edit and run. This problem isn't limited to Windows 7. It was like this with XP as well. It's not hardware related. The problem exists on both wired and wireless, Intel or Broadcom, laptops or desktops. Anyone else have this problem? Is there a GPO I can change that I missed? Got a good work-around for this? Thanks for any help!

• Cannot get to configure Kerberos for Reporting Services

  - by Ucodia

  Context I am trying to configure Kerberos in the domain for double-hop authentication. So here are the machines and their respective roles: client01: Windows 7 as client dc01: Windows Server 2008 R2 as domain controller and dns server01: Windows Server 2008 R2 as reporting server (native mode) server02: Windows Server 2008 R2 as SQL Server database engine I want my client01 to connect to server01 and configure a data source that is located on server02 using Intergrated Security. So as NTLM cannot push credentials that far, I need to setup Kerberos to enable double-hop authentication. The reporting service is runned by the Network Service service account and is configured only with the RSWindowsNegotiate options for authentication. Issue I cannot get to pass my client01 credential to server02 when configuring the data source on server01. Therefore I get the error: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. So I went on dc01 and delegated full trust for any service to server01 but it not fixed the problem. I want to notice that I did not configured any SPNs for server01 because Reporting Service is runned by Network Service and from what I read on the Internet, when Reporting Services is going up with Network Service, SPNs are automatically registered. My problem is that even if that I want to configure SPNs manually, I do not know where I have to set them up. On dc01 or on server01? So I went a bit further on the issue and tried to trace this problem. From my understanding of Kerberos, this is what should happen on the network when I try to connect the data source: client01 ---- AS_REQ ---> dc01 <--- AS_REP ---- client01 ---- TGS_REQ ---> dc01 <--- TGS_REP ---- client01 ---- AP_REQ ---> server01 <--- AP_REP ---- server01 ---- TGS_REQ ---> dc01 <--- TGS_REP ---- server01 ---- AP_REQ ---> server02 <--- AP_REP ---- So captured my local network with Wireshark, but whenever I try to configure my data source from client01 on server01 to pass my credentials to server02, my client never sends a AS_REQ or TGS_REQ to the KDC on dc01. Questions So does anyone can tell me if I should configure the SPNs and on which machine does it have to be configured? Also why client01 never request for a TGT or a TGS to my KDC. Do you think there is something going wrong with the DC role of dc01?

• [CentOS 4.8] nslookup resolves domains to IPs, but I can't get a response to pings to external servers

  - by Beco

  I have a fresh install of CentOS 4.8 running on an internal development server. I haven't done anything to it besides setting up sudoers and SSH. I can SSH into the server and from there resolve domains to IPs and ping internal servers, but for some reason I don't get any response from pinging external servers. The software firewall is disabled, and the problem is present with both static and DHCP-assigned network configurations. The network domain controller is a Windows Server 2003 box. $ nslookup google.com Server: 10.254.2.5 Address: 10.254.2.5#53 Non-authoritative answer: Name: google.com Address: 74.125.47.147 Name: google.com Address: 74.125.47.99 <etc...> 10.254.2.5 is the Win2K3 server. $ ping google.com PING google.com (74.125.47.106) 56(84) bytes of data.

• Event ID: 861 - The Windows Firewall has detected an application listening for incoming traffic

  - by Chris Marisic

  Firstly, my machines aren't compromised any person suggesting such will be DV'd. The security logs on some of my networks client machines (all Windows Xp Sp3) get filled with these useless error messages. Security Failure Audit Detailed Tracking Event ID: 861 User: NT AUTHORITY\NETWORK SERVICE The Windows Firewall has detected an application listening for incoming traffic.

I have in my global policy under AT < Network < Network Connection < Widnows Firewall < Domain Profile (I haven't changed any standard profile options do both need configured?

I'd much rather fix the problem and get rid of these entries ever being created instead of just trying to cover up the problem.

• BAT file will not run from Task Scheduler but will from Command Line

  - by wtaylor

  I'm trying to run a BAT script from Task Scheduler in Windows 2008 R2 and it runs for 3 seconds and then stops. It says it successfully completes but I know it doesn't. I can run this script from the command line directly, and it runs just fine. The bat file I'm running actually deletes files older than 7 days using "forfiles" then I'm mapping a network drive, moving the files across the network using robocopy, and then closing the network connection. I have taken the network and copy options out of the file and it still does the same thing. Here is how my file looks: rem This will delete the files from BBLEARN_stats forfiles -p "E:\BB_Maintenance_Data\DB_Backups\BBLEARN_stats" -m *.* -d -17 -c "cmd /c del @file" rem This will delete the files from BBLEARN_cms_doc forfiles -p "E:\BB_Maintenance_Data\DB_Backups\BBLEARN_cms_doc" -m *.* -d -14 -c "cmd /c del @path" rem This will delete the files from BBLEARN_admin forfiles -p "E:\BB_Maintenance_Data\DB_Backups\BBLEARN_admin" -m *.* -d -10 -c "cmd /c del @path" rem This will delete the files from BBLEARN_cms forfiles -p "E:\BB_Maintenance_Data\DB_Backups\BBLEARN_cms" -m *.* -d -10 -c "cmd /c del @path" rem This will delete the files from attendance_bb forfiles -p "E:\BB_Maintenance_Data\DB_Backups\attendance_bb" -m *.* -d -10 -c "cmd /c del @path" rem This will delete the files from BBLearn forfiles -p "E:\BB_Maintenance_Data\DB_Backups\BBLEARN" -m *.* -d -18 -c "cmd /c del @path" rem This will delete the files from Logs forfiles -p "E:\BB_Maintenance_Data\logs" -m *.* -d -10 -c "cmd /c del @path" NET USE Z: \\10.20.102.225\coursebackups\BB_DB_Backups /user:cie oly2008 ROBOCOPY E:\BB_Maintenance_Data Z: /e /XO /FFT /PURGE /NP /LOG:BB_DB_Backups.txt openfiles /disconnect /id * NET USE Z: /delete /y This is happening on 2 servers when trying to run commands from inside a BAT file.

• Exchange 2003: Fresh install, couple noob questions.

  - by Eli

  Hi All, Thanks for reading! I have a small network set up for a local office here, and have a fresh install of Exchange 2003 on our sole-server PDC. The network uses one domain, call it ourdomain.net, which is DNSed locally, but not DNSed for the actual domain, so ourdomain.net works from within the network, but from outside, it's just pointed to some domain parking. I have a completely different domain, call it emaildomain.com, which is currently setup for our website and email, which is hosted with a standard hosting company. We've been using a combination of Thunderbird and Outlook (with local .pst files) for email. I've been asked to setup Exchange to work with our email, but am not familiar with it. The install seems to have gone just fine. The question is: How do I get email from a domain outside our network to work with the exchange server? Do I need to move the email for that domain to point to our local server (I so hope not!), or can I just set exchange so somehow slurp mail from the existing mailboxes on our host for that domain's mail? Or are there better ideas I don't know to ask for? Any help very appreciated - thanks!

• No internet connection using Edimax routers

  - by idan315

  I have two computers connected to a router, connected to my ADSL modem by PPPoE. One of those computrs use Windows XP, the other uses Windows 7. The computer using Windows 7 keeps getting limited or no connectivity, and I can't use it to connect to the internet. Connecting the computer to the modem without the router 'in the way' worked, and I was able to use the internet - which led me to believe that the problem is with my router. However, I have changed my router, and the problem persists. I am really lost on how to approach this problem. Possible leads: when I view the network information, I see that my computer is connected to 'Multiple Networks'. One of those is "Network 4" (probably my router), and the other is Unidentified network. I don't know how to make the "Unidentified Network" disappear, or why is it even there in the first place. When I try using "ipconfig", I have two default gateway IPs. The first is 0.0.0.0, and the second is the IP of my router (192.168.2.1). The first router was Edimax BR-6204Wg. The second one I've tried connecting is BR-6424n. Any ideas?

• Per client DNS server assignment using Pfsense

  - by Trix

  I have a network where pfsense is the gateway. There are two sets of clients that I want. One where there will be some restrictions to the network (example, IM being blocked) and one network where there are no restrictions. One easy way I thought about doing this was assigning the different domains different DNS servers. One set could use OpenDNS, the other could use Google's Public DNS. The set with OpenDNS would have the filter options on (using OpenDNS' dashboard, I can check block IM .... so I do not manually need to block login.oscar.aol.com, meebo.com, gmail chat ....etc). So the problem is the DHCP server looks like it will only assign a single set of DNS servers to clients. Is there a way to set a per client assignment? Is there a better way to obtain what I want to obtain. This is just a small home network. I do not need anything fancy, but I do need this functionality in one way or another.

• Finding cause of TCP retransmission within a LAN

  - by Surreal

  Hello denizens of Server Fault I have an irritating problem with a LAN of about 100 computers, 2 Windows domain servers, and 12 VoIP phones. Since their installation around a year ago, every week or so, we notice a VoIP phone resetting itself - occasionally in the middle of a call. Simultaneously there are often signs of temporary loss of connection on computers: freezes in explorer while accessing network shares, errors in our administration software due to loss of connection to the database server. I have been doing some Wireshark monitoring on the connection between the VoIP PBX and the rest of the network. Wireshark picks up a clump of retransmitted TCP packets at the times when we record phone restarts. The Wireshark log shows about 2 clusters of retransmissions a day ranging from 5 packets to hundreds. Those in each cluster are mainly between the PBX and some set of the VoIP phones, but not always the same set. Often retransmissions at the same time are to phones connected to the same switch, but sometimes retransmissions occur together to phones at opposite ends of the network. There are usually some coincident retransmissions in passing TCP traffic, for example between client machines and the file servers. The spikes in retransmissions and phone resets do not correlate well with when the network is heavily loaded. They seem to occur slightly more during the day, but most in the evening, when traffic should be decreasing. They occur reasonably often late at night when most computers are turned off and traffic should be lowest. Do you have any ideas that might help diagnose the cause of problems like this? One thing I have not yet tried, but should have, is updating the firmware of all the switches.

• VMWare Server Windows 2008 NAT Problem

  - by David

  At my new job our workstations run Windows Server 2008. However, for the specific task for which I've been hired, I need to set up a couple Linux VMs. So I grabbed the free VMWare Server and created an Ubuntu image and a Slackware image. (The former to more closely mimic the production server, the latter because I'm more familiar with it.) For desktop security purposes I need to use NAT for the network access (I would have preferred bridged, but I'm told that would go against some policy here and my whole workstation would be sandboxed from the switch). However, I can't seem to get it working right. I can ping out from the VMs to LAN addresses as well as internet addresses. I can resolve DNS names. However, attempts to use a web browser or perform any kind of higher-level interaction like that just time out. Googling around yesterday led me to various workarounds that were similar, but didn't solve my specific situation. (For example, Norton firewall blocking the connection on the host, or even the Windows firewall.) I also saw some forum posts where people said it's a known issue with VMWare and Windows Server 2008 (and Windows 7). So far I haven't been able to find a suggestion that gets me past this roadblock. I'm really not very familiar with managing a Windows Server 2008 box, so it's possible there's just some security setting somewhere that I need to modify. Does anybody have any suggestions on where I should look? UPDATE: I'm now looking at the "Network and Sharing Center" on the host workstation and it shows "VMWare Network Adapter VMnet8" (which is what I'm using) as an "Unidentified network" with "No Internet access." Looks like I can't modify ICS under the group policy. Any suggestions on how to allow this connection to have internet access?

• DNAT to 127.0.0.1 with iptables / Destination access control for transparent SOCKS proxy

  - by cdauth

  I have a server running on my local network that acts as a router for the computers in my network. I want to achieve now that outgoing TCP requests to certain IP addresses are tunnelled through an SSH connection, without giving the people from my network the possibility to use that SSH tunnel to connect to arbitrary hosts. The approach I had in mind until now was to have an instance of redsocks listening on localhost and to redirect all outgoing requests to the IP addresses I want to divert to that redsocks instance. I added the following iptables rule: iptables -t nat -A PREROUTING -p tcp -d 1.2.3.4 -j DNAT --to-destination 127.0.0.1:12345 Apparently, the Linux kernel considers packets coming from a non-127.0.0.0/8 address to an 127.0.0.0/8 address as “Martian packets” and drops them. What worked, though, was to have redsocks listen on eth0 instead of lo and then have iptables DNAT the packets to the eth0 address instead (or using a REDIRECT rule). The problem about this is that then every computer on my network can use the redsocks instance to connect to every host on the internet, but I want to limit its usage to a certain set of IP addresses only. Is there any way to make iptables DNAT packets to 127.0.0.1? Otherwise, does anyone have an idea how I could achieve my goal without opening up the tunnel to everyone? Update: I have also tried to change the source of the packets, without any success: iptables -t nat -A POSTROUTING -p tcp -s 192.168.1.0/24 -d 1.2.3.4 -j SNAT --to-source 127.0.0.1 iptables -t nat -A POSTROUTING -p tcp -s 192.168.1.0/24 -d 127.0.0.1 -j SNAT --to-source 127.0.0.1

• Using dnsmasq for accessing multiple nameservers assigned by DHCP

  - by Ash

  At my work desktop running openSUSE 11.4, I have a local network which gets its address, domain (work.site) and nameservers (10.100.1.1, 10.100.1.2) info through DHCP - which get written into /etc/resolv.conf I get to access the internet using the work network, and these 2 nameservers end up returning the entries for any public domain name lookups on the internet. I also have a private VPN that I end up connecting. The nameserver (10.111.1.1) and domain (private.site) are rarely bound to change for this network, but currently they're pushed by the openVPN client into networkmanager, and which also gets merged with the existing /etc/resolv.conf My resolv.conf ultimately ends up looking like this: search private.site work.site nameserver 127.0.0.1 nameserver 10.111.1.1 nameserver 10.100.1.1 As you can see the 2nd nameserver from my work network was pushed out because of the max 3 entry limitations. It is fine still, but would be a problem if that nameserver goes down for maintenance or something. So I found out that dnsmasq could help me here, and hence I setup dnsmasq just as a local DNS resolver without any DHCP support. So right now this is my /etc/dnsmasq.conf: resolv-file=/etc/resolv.conf server=/private.site/10.111.1.1 server=/1.111.10.in-addr.arpa/10.111.1.1 listen-address=127.0.0.1 bind-interfaces log-queries I've made dnsmasq get the list of nameservers from /etc/resolv.conf since NetworkManager seems to be updating this list correctly (for a max of 3 nameservers). I'm able to resolve the host names in both the networks correctly. So these are the questions I have: Is there a way I can make either NetworkManager or dhclient write out the list of nameservers somewhere else which I can make dnsmasq use as resolv-file ? How do I make dnsmasq use certain nameservers as the default for all queries ? Right now I notice that lookups for public domains on the internet are usually sent to both the nameservers - the one on work.site as well as private.site. It would be good if I can limit this only to work.site.

• Windows Server 2008 DHCP with RRAS

  - by Guillermo Prandi

  I have a Windows Server 2008 R2 which is a member of a domain, but is placed in a remote location. The server is directly connected to Internet. Clients need to access a particular insecure TCP service in this server (ports 9730 and 9731). Since clients have dynamic IP addresses I cannot know in advance, I thought it would be nice to have them connected through a VPN in order to access the insecure service, but ONLY to access that service, like this: Client ------> VPN TUNNEL ------> (Insecure service at Server) | \----> (Normal internet access) I'd enable the insecure ports in the firewall only from VPN accesses. For this I configured RRAS in the server and gave it a static IP address range (172.19.1.2 through 172.19.1.254) to serve the clients. First I thought I could use DHCP to assign the addresses, but I cannot use DHCP in my LAN connection (not allowed by the hosting service). I tried configuring DHCP binding it to a Microsoft Loopback Adapter, but that's not supported as a DHCP source by RRAS. What I want to accomplish is to send specific DHCP options to the client (network mask, routing table, etc.). In particular: Prevent the client from having the server as default router (without changing the client's "use default gateway in remote network"). Have it as a route for the server's internal RRAS address only (172.19.1.1). Prevent the client from using a 255.255.0.0 mask for the 172.19.x.x network (a 255.255.255.0 mask would be better). Can I do that with RRAS only? How? Currently, the only solution I can think of is to use DHCP in the LAN adapter, but filter DHCP packets so they don't reach the provider's network. However, I'm not sure if that will work. Any suggestions are welcomed! Guille

• How do I fix this Windows 7 wireless connectivity issue?

  - by Charles Randall

  I have a laptop with an Intel Wireless Centrino 6300 module. Recently, the machine has stopped properly connecting to my wireless router. It will get stuck in a loop of connecting, then disconnecting and reconnecting. While connected, it will simply say "No Internet Access." Running inSSIDer 2.0, it shows my network jumping around between two channels -- I know this isn't the case, because I've set my router to sit on one single channel. My MacBook Pro, Boxee Box, PS3, and Xbox 360 all connect fine to the wireless and have no problems at all. I know it's not the wireless module, as I bought a second one recently assuming the first had died -- but I get the same behavior with both. Sometimes, I can fix the issue temporarily by deleting the network (Using the Manage Wireless Networks page), and then re-adding it (via standard wireless methods). Then it will work for a few days. But inevitably the problem comes back, and now the laptop simply won't connect to the wireless at all, even if I take steps that usually work. Since I've ruled out the hardware, and it's unlikely some kind of interference issue (because I would expect to see it on any multitude of other devices), I would think at this point that it's a problem with Windows itself. One thing that might be a hint, even though I delete the network, when I add it again, it's always listed as "Wireless Network Connection 2" even though there isn't another in the list.

• client flips between internal and external IP addresses??

  - by jmiller-miramontes

  I have what seems like a not-particularly-complicated home network, all things considered: a DSL line comes in to a modem/router, which goes off to a switch, which supports a bunch of machines. My machines live in a 192.168.0.x address space; however, I'm running some public servers on the network, so I have a block of 8 (5, really) static IP addresses that are mapped to the servers by the router. The non-servers get 192.168.0.x addresses via NAT; some machines have static addresses and some get addresses from DHCP. Locally, I'm running a DNS server (named) to map between the domain names and the 192.168 address space. Somewhat messy, but everything basically works. Except: One of my local non-server clients occasionally switches from its internal address to its external address. That is, if I check the logs of a website I'm running internally, the hits coming from this client sometimes show up with the internal 192.168 address, and sometimes with the external (216.103...) address. It will flip back and forth for no apparent reason, without my doing anything. This can be a problem in terms of how the clients interact with the way I have some of the clients' SSH systems configured (e.g., allowing access from the internal network but not the external network), but it also Just Seems Wrong. I will confess that I'm kinda skating on the very edge of my networking competence here, but I can't for the life of me figure out what's going on. If it helps, the client in question is running Mac OS X / 10.6; its address is statically assigned, is not one of the five externally-accessible addresses, and gets its DNS from (first) the internal DNS server and (second) my ISP's DNS servers. I can't swear that none of the other NAT clients are also showing this problem; the one I'm dealing with is my everyday machine, so this is where I run into it. Does anybody out there have any advice? This is driving me crazy...

• How to bypass firewall to connect to a proxy server?

  - by Bruce

  I am conducting a small experiment on my office network. I have setup a proxy server on my desktop machine (connected to my LAN) and I have volunteers access the internet via my proxy server. Everything is working well. The problem is people cannot connect to the proxy server through their laptops. I asked my network admin and he said the wireless network has a firewall which prevents users from connecting to my proxy. He said I could tunnel the traffic or use SSH though. I am afraid I do not understand fully what is going on. Is there a way by which users connected on the wireless network can connect to my desktop? I am using FreeProxy on Windows as my proxy server: http://www.handcraftedsoftware.org/index.php?page=download FreeProxy allows me to create a SOCKS 4/4a/5 proxy. Is that what I need? Part of the experiment involves logging the URL requests of the users. I am doing a measurement study. So, any solution must allow me to log the URL requests of users. Also, what changes do I need to make in the browser configuration.

• Linksys WAP54G v3.1 no access, power and link LED solid

  - by user142113

  I'm managing the Network of a small enterprise. A Linksys WAP54G v3.1 used to provide the WiFi network. I was called, because the device did not provide a WiFi network anymore. I first of all tried to ping the device via LAN, but there was no reaction. I've frequently reconnected the AP to the mains and always the POWER and the LINK LED keep solid, even if no network cable is connected. What I've done yet: Reset as documented: Pressed the RESET button for 10 seconds. After that I have tried to access the AP with a direct cable connection to my computer, that I've set to a static ip of 192.168.1.240, but i got no ping response on the default IP 192.168.1.245. Furthermore ipconfig reports "media disconnected". More complex reset method as described here http://bruceshankle.blogspot.de/2005/12/how-to-reset-linksys-wap54g.html as well had no effect. also tried to ping 192.168.1.1 without success Tried this method: http://www.daniweb.com/hardware-and-software/networking/threads/142437/linksys-wireless-access-point-problem#post680245 but there was no ping response when powering up. As well the tftp transfer timed out Finally tried to short pin 15 and 16 of the flash chip on the bottom side of the AP mainboard while booting to provoke a Checksum error. This should lead to the possibility to upload a firmware with tftp, as the AP stops booting and waits for a tftp connection on 192.168.1.1. But I've had no success. As well i've put pin 15 and 16 to ground while booting, also without an effect. After all that I still can't ping the AP, ipconfig still tells me "media disconnected". The POWER and LINK LED are solid. I would appreciate your answers
