• How to create a static IP on Windows Server 2008 R2 so I can access the server remotely

  - by Aesir

  I have just purchased a HP Proliant N40L which I am intending to use as a NAS, learning tool and just in general something to mess around with. As a student via the Microsoft dreamspark program I can get a free copy of Windows Server 2008 R2 which I am using as the OS. So that I can remote to the box from outside of my local network and so that I can stream media from it to my PS3, I have read that I need to create a static IP for the server and use port forwarding to forward to this IP so I can remote in. Is this correct? I am not really sure how to do this and if I need to make these changes on my router configuration, on the OS or both. I am a novice when it comes to networking however most resources for Windows server 2008 R2 seem to assume a fair amount of experience already. I realise that using this particular OS may seem like overkill for what I currently wish to do with it (stream content to other devices and backup) but as I can get a copy for free it seems sensible. Edit: From reading answers posted I feel I should give more information. I have now tried to add a static IP address using my router configuration settings. I have used the getmac command to get the mac address of the server. My ISP is Virgin Media and I have gone to the LAN IP section and I have added an IP address to the DHCP Reservation Lease Info. I can now use remote desktop connection internally to remote to the server (so I am assuming assigning this IP has worked). How do I configure this on the OS as well? I am also unsure on how I would remote to this machine outside of my local network?

• How can I setup OpenVPN with IPv4 and IPv6 using a tap device?

  - by Lekensteyn

  I've managed to setup OpenVPN for full IPv4 connectivity using tap0. Now I want to do the same for IPv6. Addresses and network setup (note that my real prefix is replaced by 2001:db8): 2001:db8::100:0:0/96 my assigned IPv6 range 2001:db8::100:abc:0/112 OpenVPN IPv6 range 2001:db8::100:abc:1 tap0 (on server) (set as gateway on client) 2001:db8::100:abc:2 tap0 (on client) 2001:db8::1:2:3:4 gateway for server Home laptop (tap0: 2001:db8::100:abc:2/112 gateway 2001:db8::100:abc:1/112) | | | (running Kubuntu 10.10; OpenVPN 2.1.0-3ubuntu1) | wifi | | router | | OpenVPN INTERNET | eth0 | /tap0 VPS (eth0:2001:db8::1:2:3:4/64 gateway 2001:db8::1) (tap0: 2001:db8::100:abc:1/112) (running Debian 6; OpenVPN 2.1.3-2) The server has both native IPv4 and IPv6 connectivity, the client has only IPv4. I can ping6 to and from my server over OpenVPN, but not to other machines (for example, ipv6.google.com). net.ipv6.conf.all.forwarding is set to 1, I've tried disabling net.ipv6.conf.all.accept_ra as well, without luck. Using tcpdump on both the server and client, I can see that packets are actually transferred over tap0 to eth0. The router (2001:db8::1) send a neighbor solicitation for the client (2001:db8::100:abc:2) to eth0 after it receives the ICMP6 echo-request. The server does not respond to that solicitation, which causes the ICMP6 echo-request not be routed to the destination. How can I make this IPv6 connection work?

• Apache local verses external (domain)

  - by Jessy Houle

  I have an Apache server running on Ubuntu server 10, using Passenger for Ruby on Rails. I have configured my site under the sites-enabled directory of Apache and can hit the server with an internal IP address (192.168.X.X) and the site comes back as expected. However, whenever I try to hit the site externally, either through the domain name or the IP address tied to the domain name, the site will not come back. I have a router in the middle with a static IP address, with Port Forwarding turned on (forwarding 80/443) to the server and I'm quite confident the issue isn't there. In fact, I even DMZed to the Ubuntu Server just to make sure. Also, all router firewall options have been turned off. So here is the question... Is there something else I have to do with Ubuntu server to allow externally requested port 80 traffic? Otherwise, is there some settings that need to be set in Apache to allow domain or external IP address port 80 traffic through? I'm pretty new to Apache, so, please take it a bit easy on me :-) Thank you for your responses. -Jessy Houle

• Find routers IP address on the other side

  - by corsiKa

  Here's the basic setup of my network In this diagram: 1: The internet c: cable 2: Wireless router w: wireless connection 3: A win7 box with internet connection sharing enabled 4: A wireless router, but I'm only using its LAN capabilities to connect box 5 to the internet. 5: A win7 box, the computer I'm using to make this post. So its internet works just fine. Now if I'm on box 5, and I ping 192.168.1.1, I hit 4. If I'm on box 3 and I ping 192.168.1.1, I hit 2. Now obviously box 3 does not think 4's IP address is 192.168.1.1, or I wouldn't be able to connect to the internet. Okay, now that you know as much as I do about my network, here's my question: If I was on box 3, how would I determine the IP address of 4? Basically I'm running a webserver on box 5 and want to access this webserver on box 3 and other boxes. So that's the end goal. If there's other information there that can help, I'd appreciate it. Thanks!

• 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.

• Can I autoregister my servers hostname in my local DNS? [on hold]

  - by Christian Wattengård

  We have evaluated a W2k12 server as a domain controller at work. This has the extra benefit of registering every "subordinate" computers name in it's DNS so that I don't have to go around remembering IP's all the time. (And it let's me easily run dhcp also on my "pop-up" dev-servers). We need to rework our work network for several odd reasons, and in this new scenario there was no money for an extra Windows 2012 license. We have at our disposal several old boxes that run linux quite well. Is it possible to set up a DNS-server-"appliance" that somehow autoregisters it's own hostname.. Scenario: Router (N66u) on 172.20.20.1. Runs DHCP on 172.20.20.100-200 range. Server [verdant] of a *nix flavor on 172.20.20.2 Laptop [speedy] of W8 flavor on DHCP assigned Laptop [canary] of W8 flavor on DHCP assigned Desktop [lianyu] of Ubuntu flavor on DHCP assigned What I would like is that all of the above servers (except possibly the router) would be available on verdant.starling.lan and canary.starling.lan and so on. This is how it works right now (except the Ubuntu box... I haven't cracked that one yet) because Windows just does this for you.. I would also be able to do this without any manual labor on the server. When I tell my box it's name is smoak it should "immediately" be available as smoak.starling.lan without any extra configuration on my part. How can I do this in a Linux (Ubuntu) environment?

• What's the best way to telnet from a remote Windows PC without using RDP?

  - by Rob D.

  Three Networks: 10.1.1.0 - Mine 172.1.1.0 - My Branch Office 172.2.2.0 - My Branch Office's VOIP VLAN. My PC is on 10.1.1.0. I need to telnet into a Cisco router on 172.2.2.0. The 10.1.1.0 network has no routes to 172.2.2.0, but a VPN connects 10.1.1.0 to 172.1.1.0. Traffic on 172.1.1.0 can route to 172.2.2.0. All PCs on 172.1.1.0 are running Windows XP. Without disrupting anyone using those PCs, I want to open a telnet session from one of those PCs to the router on 172.2.2.0. I've tried the following: psexec.exe \\branchpc telnet 172.2.2.1 psexec.exe \\branchpc cmd.exe telnet 172.2.2.1 psexec.exe \\branchpc -c plink -telnet 172.2.2.1 Methods 1 and 2 both failed because telnet.exe is not usable over psexec. Method 3 actually succeeded in creating the connection, but I cannot login because the session registers my carriage return twice. My password is always blank because at the "Username:" prompt I'm effectively typing: Routeruser[ENTER][ENTER] It's probably time to deploy WinRM... Does anyone know of any other alternatives? Does anyone know how I can fix plink.exe so it only receives one carriage return when I use it over psexec?

• Ubuntu: Network connection seems to fail after some time

  - by chrischu

  I just bought a Shuttle XS-35 barebone mini-PC and put a 1 TB WD hard drive and 2 Gigs of RAM into it and installed Ubuntu onto it. The machine will post as a media server (streaming videos to my PS3) and as a webserver for some small private projects. Now I wanted to copy my videos from my Windows 7 machine to the Ubuntu machine and therefore created a Samba share on the Ubuntu machine. I tried copying the files with the standard Windows copy function and with SyncToy but after some time (sometimes 5 copied files, sometimes 120 copied files) the Samba share just disappears. When that happens I can't reach the internet from the Ubuntu machine although the network connection still seems to be fine (IP still there etc.). Between the machines lies a LinkSys router. When I try to ping my router (after the connection doesn't work anymore) from the Ubuntu machine only a very small subset of the packages actually get there (something around 20%). When I restart the Ubuntu machine everything seems to work normal again. I have no idea where the problem lies here. Does anybody have a clue? Thanks in advance!

• Vyatta masquerade out bridge interface

  - by miquella

  We have set up a Vyatta Core 6.1 gateway on our network with three interfaces: eth0 - 1.1.1.1 - public gateway/router IP (to public upstream router) eth1 - 2.2.2.1/24 - public subnet (connected to a second firewall 2.2.2.2) eth2 - 10.10.0.1/24 - private subnet Our ISP provided the 1.1.1.1 address for us to use as our gateway. The 2.2.2.1 address is so the other firewall (2.2.2.2) can communicate to this gateway which then routes the traffic out through the eth0 interface. Here is our current configuration: interfaces { bridge br100 { address 2.2.2.1/24 } ethernet eth0 { address 1.1.1.1/30 vif 100 { bridge-group { bridge br100 } } } ethernet eth1 { bridge-group { bridge br100 } } ethernet eth2 { address 10.10.0.1/24 } loopback lo { } } service { nat { rule 100 { outbound-interface eth0 source { address 10.10.0.1/24 } type masquerade } } } With this configuration, it routes everything, but the source address after masquerading is 1.1.1.1, which is correct, because that's the interface it's bound to. But because of some of our requirements here, we need it to source from the 2.2.2.1 address instead (what's the point of paying for a class C public subnet if the only address we can send from is our gateway!?). I've tried binding to br100 instead of eth0, but it doesn't seem to route anything if I do that. I imagine I'm just missing something simple. Any thoughts?

• I just got a virus 6 mins ago, how? Situation.

  - by acidzombie24

  -Edit- for the people who say it isn't a virus. Norton does detect it as a virus, an icon was placed on my system tray and rkpg.exe is in my C: which was placed 6 min ago around the time my computer rebooted on its own causing me to lose data :@. Situation I on Windows XP, behind a Linksys router, I don't have DMZ on so nothing should be connecting to me. I had Firefox, MSN and Visual Studio opened. With C# I programmed a quick application to scan some pages with Internet Explorer. The site it was scanning was deviantART (which is pretty trustworthy), I doubt any banners there would hold a virus. I went to a suspicious site called freetxt.com but that was on Firefox and it didn't load the site. With an extra check I ping it and got this message "Ping request could not find host freetxt.com." The virus seems to be called braviax. Right now it brought up a message saying my computer may be infected? How on earth did it get in? I don't have uTorrent installed or any torrent or p2p applications. Nothing is installed on my computer that I haven't installed before and I know the exact time it installed because I see rkpg.exe on my C drive and my computer restarted on its own around the same time. For the previous 30 minutes actually the previous hour all I did was talk on MSN, not click any links (I went to freetxt on my own) and had that Internet Explorer thing running (which I programmed). How did it get in? I really doubt it came from a banner on deviantART and installed when I loaded the page with the webbrowser-control so something else may have happened? Is there any system defaults I should turn off? I have remote assistance off but even if it was on I shouldn't be infected due to the router not forwarding any ports?

• Change source address based on destination IP

  - by hgj

  We have several "router" machines that gather a lot of external IP addresses on the same host and redirect, NAT or proxy the traffic to the internal network. They also act as routers for the machines on the internal network. This works fine, however I am unable to make the routing table, so I can change the source address, based on the destination a machine from the internal network want to access. Let's say I have a router, that has public addresses P1 (5.5.5.1/24) and P2 (5.5.5.2/24). All traffic goes through P1, but if necessary, the host is reachable on P2 too. This looks like this and works fine: > ip addr ... 1: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether aa:bb:cc:dd:ee:11 brd ff:ff:ff:ff:ff:ff inet 5.5.5.1/24 brd 5.5.5.255 scope global eth1 inet 5.5.5.2/24 brd 5.5.5.255 scope global secondary eth1:p2 ... Now I want to use P2 as the source address, if I want to access the Google DNS service for example (8.8.8.8). So I add a row in the routing table like: > ip route add 8.8.8.8 via 5.5.5.254 dev eth1 src 5.5.5.2 > ip route ... default via 5.5.5.254 dev eth1 5.5.5.0/24 dev eth1 proto kernel scope link src 5.5.5.1 8.8.8.8 via 5.5.5.254 dev eth1 src 5.5.5.2 ... But this does not work. If I ping 8.8.8.8, the host still uses P1 as the source address, and does not use P2 at all for outgoing connections. Am I doing it right? I guess not...

• SSH connection times out unless I tunnel in from a different server-

  - by rm-vanda

  OK, so this just started last week - Whenever we try to connect to our server via ssh (we use sftp, as well) - The connection times out. However, when you ssh to any other server and then ssh into the machine - it works flawlessly. Now, the mindblowing thing is that sometimes the ssh connection will succeed. Moments ago, I tried it from another machine, and then my own, and it worked - only to time out the next go around. Last week, simply restarting the ssh daemon worked, but this week, no such luck. I even went in and changed: /etc/hosts.allow ALL : ALL and /etc/hosts.deny is blank. The firewall config hasn't changed - but I even disabled the firewall to see if that would work - It did, for a moment - before cutting off, again. (ufw is set to "ALLOW" not "LIMIT") When I try SSH'ing in from my phone -- it works, fine -- So, it seems the problem is with our ISP/router/gateway - However, I see no log in the router/gateway that says its blocking our connections - And that wouldn't explain why we can SSH into any other server -- except for this one - from our network --- I truly appreciate any insight that anyone may have on this matter -

• Slow upload, fast download on Windows 7 64bit system

  - by Malik

  I've got a weird problem in the download speeds on my desktop PC (Windows 7 Home Premium 64bit) are consistently fast (approx. 400kB/s) but uploads are very slow (around 6-10kB/s). This has been going on for the last 3 weeks or so. I am a very competent user and troubleshooter, and have searched online for 2 weeks for a solution, to no avail. Part of the problem is that internet is provided by WiFi by my landlord and I have no access to the router (BT Home Hub router) although I know for sure he wouldn't have the first idea on how to restrict my usage :) (rules that out) Anyway, I've tried: - various drivers (my Wifi 'card' is TP-link TL-WN851N, and I've tried TP-link + Atheros + Qualcomm Atheross drivers, suggested by Microsoft) - various tweaks to network parameters (e.g. as suggested by SpeedOptimser) - various tweaks to Windows 7 services (e.g. disabling/manual-ing unecessary services) - raising and lowering head onto a reasonably firm surface at moderate frequency (jk :D) None of the above have helped, and I'm officialy asking for help now!! Thanks for your time and effort in advance!

• SSH Connection Error : No route to host

  - by dewbot

  There are three machines in this scenario: Desktop A : [email protected] Laptop A : [email protected] Machine B : [email protected] All the machines have Ubuntu 11.04 (Desktop A is a 64bit one) and have both openssh-server and openssh-client. Now when I try to connect Desktop A to Laptop A or vice-versa by ssh [email protected] I get an error as port 22: No route to host in both the cases. I own both the machines, now if I try same commands from my friend's machine, i.e. via Desktop B, I can access both my Laptop and Desktop. But if I try to access Desktop B from my Laptop or by Desktop I get port 22: Connection timed out I even tried changing ssh port no. in ssh_config file but no success. Note: that 'Laptop A' uses WiFi connection while 'Machine A' uses Ethernet Connection and 'Machine B' is on an entirely different network. Laptop A && Desktop A - Router/Nano_Rcvr provided to me by ISP. So to one Router two Machines are connected and can be accessed at the same time. here is my ifconfig output for both the machines :- Laptop wlan0 Link encap:Ethernet HWaddr X:X:X:X:00:bc inet addr:1.23.73.111 Bcast:1.23.95.255 Mask:255.255.224.0 inet6 addr: fe80::219:e3ff:fe04:bc/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:108409 errors:0 dropped:0 overruns:0 frame:0 TX packets:82523 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:44974080 (44.9 MB) TX bytes:22973031 (22.9 MB) Desktop eth0 Link encap:Ethernet HWaddr X:X:X:X:c5:78 inet addr:1.23.68.209 Bcast:1.23.95.255 Mask:255.255.224.0 inet6 addr: fe80::227:eff:fe04:c578/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:10380 errors:0 dropped:0 overruns:0 frame:0 TX packets:4509 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1790366 (1.7 MB) TX bytes:852877 (852.8 KB) Interrupt:43 Base address:0x2000

• Curious enigma of a network cable / connection / quality

  - by Foo Bar

  So, the situation is like this: I'm renting an apartment in a large house and I'm sharing internet with the landlord who lives downstairs. The internet is (in my best guess) optical 20/20Mbit. I don't know how it's all wired in his flat (haven't been there / seen it). Anyway, in my flat comes a cable which seems to be connected directly to the optic to ethernet router (and the password is the default one, so I have access, he he). There was a switch connected to that and to wires that go around the flat, and the wiring is terrible. It's even mixing phone and ethernet, and from what I see some cables are even interconnected!? Anyways, this cable that comes to my flat is very short. I can barely connect my computer on it, but if I do, I seem to get decent speed / performance. Not great, but decent. If, however, I connect switch to it (tried 2 different switches and a wifi switch) it's all blinking but I can't even connect to 192.168.1.1 (the router). DHCP fails, ping is losing 80-100% of replies. So I connected this cable directly to the other cable which goes to my work room, with a connector that has two female jacks and no electronics. Now when I connect my computer in my room, again, the performance is decent. When I connect WRT54GL (with tomato, DHCP disabled) to it and I plug a cable in this WRT and to my computer... the performance is gone. Download seems okay on Speedtest, but upload is .2Mbps and it's connecting forever. So what kind cable troll am I having here? Any ideas?

• System With Two Network Adapters

  - by Synetech inc.

  Hi, My system has a NIC (Marvell Yukon) built-into the motherboard, but I also have a D-Link (RealTek) card. I figure that using the D-Link and disabling the Marvell makes the most sense, though I'm wondering if maybe the built-in one has better throughput (not that my Internet connection is so fast). Also, I'm wondering about the merits of using both at the same time. My router has four ports and I have experimented with enabling and plugging both NICs into the router. I was able to connect to the Internet, but the pattern of usage seemed irregular (which adapter was chosen for the transfer and any given point). I also considered bridging the two, but am having difficulty in finding out what exactly creating network bridge does in the context of the Windows Network Connections window. I am familiar with the concept of connecting networks, so it seems to me that birding two connections on the same segment is pointless at best (and can cause problems like loops?) Does anyone have any tips on what to do if a system has more than one NIC and any clarification on the bridge option? Thanks a lot.

• Monitoring instantaneous network throughput at one second intervals?

  - by Shaddi

  For a testing setup I have, I need to monitor the throughput through a "router"* at regular intervals of around 5 seconds or less (sub-second intervals would be very nice, but not required). Ideally, I would be able to generate a file which contained both the number of bytes and packets seen during each interval. I will eventually be generating a time-series of throughput from this data. On a previous setup using an older version of FreeBSD, there was a tool called "bpfmon" which gave me this information. However, I need to do this under a modern version of Linux (namely, Ubuntu 11.04). I have looked at both iptraf and iftop, but these do not appear to provide the resolution I need, nor do they seem to easily allow scraping the data I need. I understand iptables statistics may be able to give me what I'm after, but the examples I've seen of this seem to rely on repeatedly reading and resetting traffic counters, which seems like it could give inaccurate as read/reset is not an atomic operation. I already capture a tcpdump trace of the traffic I'm interested in on the link I want to monitor, so I am open to approaches which simply parse that. I feel like this must be a common problem though, so I am hoping there will be a standard "best practice" tool for accomplishing this. *I say "router" in quotes because I am really talking about a machine with two bridged NICs through which all the traffic I'm interested in passes.

• How to set up Windows 7 Professional as a NAS

  - by Enyalius

  I searched and didn't find any answers, so please forgive me if this is a repeat. Anyway, I have an older computer that I'm using as an HTPC, and I was hoping that I could use it as a NAS/multimedia server, as well. My primary uses would include accessing content on my PS3 (same LAN), accessing content from other computers on my home network and (if I can) accessing content from my Android phone over the internet. I have used SubSonic to stream music to my Android phone and other computers before, but I would really like to find a way to do this natively if possible. I know that I can buy external hard disk cases that can plug in the USB port of my router, that I can get a Drobo or other network storage solution, but I would really just rather not spend the money (especially considering that I already have a computer that I should be able to use). Hardware involved: Apple AirPort Extreme base station router (most recent revision) Home Theater Personal Computer: Core 2 Duo @ 2.4GHz, 8GB DDR2 RAM, ~3.5TB hard drive space Sony Playstaiton 3 Thin 120GB HTC Thunderbolt (I have 4G coverage) rooted and running Android 2.2.1 Various Apple laptops Various Windows 7 desktops/laptops Thanks in advance! Note- I have looked at open source NAS software but I would like to preserve the Windows Media Center functionality in Windows 7, so other NAS software is not an option for me currently. .

I am familiar with the concept of connecting networks, so it seems to me that birding two connections on the same segment is pointless at best (and can cause problems like loops?) Does anyone have any tips on what to do if a system has more than one NIC and any clarification on the bridge option? Thanks a lot.

• 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.

• Watchguard Firebox "split" fibre optic line into 2 interfaces

  - by fRAiLtY-

  We have a requirement on our Watchguard Firebox XTM505 to be able to split our incoming external interface, in this case a fibre optic dedicated leased line, 100/100. We use the line in our office of approx 30 machines however we also re-sell to an external company who utilise it to provide wireless internet solutions to the public. The current infrastructure is as follows: Data in (Leased Line) - Juniper SRX210 managed by ISP - 1 cable out into unmanaged Netgear switch - 1 cable into our firewall and office network, 1 cable to our external providers core router managed by them. We have been informed that having the unmanaged switch in the position it is poses a security risk and that a good option would be to get our Watchguard Firewall to perform the split, by separating our office onto a trusted interface, and by "passing through" the external line to their managed router. It is alleged that the Watchguard is capable of doing this and also rate limiting the interfaces, i.e. 20mbps for the trusted interface and 80mbps for the "pass-through", however Watchguard technical support don't seem to be able to understand what we're trying to achieve. Can anyone provide any advice on whether this is possible on a Watchguard device and how or perhaps if there's a better way of achieving this, perhaps with a managed switch instead of unmanaged? Cheers

• TCP/UDP hole punching from and to the same NAT network

  - by Luc

  I was wondering if tcp/udp hole punching would still work when you are in the same network (behind a NAT), and what the packet's path would be. What happens when using hole punching on the same network, is that it will send a packet out with the same destination and source address. Only the source and destination port would differ. I imagine a router with NAT loopback enabled will handle this as it should, but how about other routers? Would they drop the packet, or would a router (the first?) from the ISP bounce the packet back after which it gets handled okay? I'm wondering because I was thinking about using this technique to circumvent a block between peers in a network (like a school network where clients can only access the internet, but any contact with each other is blocked). The only other option is to use a man in the middle as proxy (tunnel?). The disadvantage of this is that you have to have a server with significantly more bandwidth than one that would only do hole punching. Also the latency would increase significantly.

• VirtualBox with Ubuntu Server guest can't ping outside

  - by Danidan

  Here's my situation: an Ubuntu 12.04 Host running VirtualBox; two guest VMs running Ubuntu Server 12.04 home network, so my Host pc has a wireless connection to the router of my ISP. My problem is in one of the virtual machines: it has 3 NICs, one in NAT mode and the others in Host Only mode. My purpose is to use eth0 (NAT) for Internet access and eth1, eth2 (Host Only) for management of internal virtual network (eth1 uses a VBoxNet with this IP 192.168.69.254). Whenever I try to $ping 8.8.8.8 I get Destination Host Unreachable. While if I $ping 192.168.69.10, that is the IP of the other VM, it works. I can't also ping my Host nor my router My /etc/network/interfaces file is: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 inet static address 192.168.69.1 netmask 255.255.255.0 auto eth2 iface ifconfig $IFACE 0.0.0.0 up up ip link set $IFACE promisc on down ip link set $IFASE promisc off down ifconfig $IFACE down $route -n returns: Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.0.2.2 0.0.0.0 UG 100 0 0 eth0 10.0.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.69.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0 Forgetting for now what eth2 needs to do and its setup, why I can't go outside the Host box? What can I do to help you helping me? :-)

• Exim, hot to route local mail to other adress

  - by kheraud

  I have setuped an Exim4 server on my debian wheezy server. This mail server only sends mail coming from localhost. The purpose is sending mail for my website. I have cron tasks and other services generating mails for root user. These mails are not stored in /var/mail as before, but sent by exim to [email protected]. I try to make exim send mails for root to [email protected] rather than [email protected]. I tried adding a .forward in /root with [email protected] as content. I tried also changing /etc/aliases with root: [email protected]. The fact is that routing works for root@localhost but not for root which is resolved as [email protected] I tested how routing is resolved with exim -bt : root@srv02:~# exim -bt root@localhost R: system_aliases for root@localhost R: dnslookup for [email protected] [email protected] <-- root@localhost router = dnslookup, transport = remote_smtp host gmail-smtp-in.l.google.com [173.194.67.27] MX=5 host alt1.gmail-smtp-in.l.google.com [74.125.143.27] MX=10 host alt2.gmail-smtp-in.l.google.com [74.125.25.27] MX=20 host alt3.gmail-smtp-in.l.google.com [173.194.64.27] MX=30 host alt4.gmail-smtp-in.l.google.com [74.125.142.27] MX=40 root@srv02:~# exim -bt root R: dnslookup for [email protected] [email protected] router = dnslookup, transport = remote_smtp host aspmx.l.google.com [173.194.78.27] MX=1 host alt1.aspmx.l.google.com [74.125.143.27] MX=5 host alt2.aspmx.l.google.com [74.125.25.27] MX=5 host alt4.aspmx.l.google.com [74.125.142.27] MX=10 host alt3.aspmx.l.google.com [173.194.64.27] MX=10 I bet this is a matter of how my server is configured (rather than how exim is configured). But to understand well I would like to have a solution for both : how to have root resolved as root@localhost ? how to have [email protected] routed to [email protected] ?
