• VirtualBox Port Forward not working when Guest IP *IS* specified (while doc says opposite)

  - by Patrick

  Trying to port forward from host (Mac OS X) 127.0.0.1:8282 - guest (CentOS)'s 10.10.10.10:8080. Existing port forwards include 127.0.0.1:8181 and 9191 to guest without any IP specified (so whatever it gets through DHCP, as explained in the documentation). Here is how the non-working binding was added: VBoxManage modifyvm "VM name" --natpf1 "rule3,tcp,127.0.0.1,8282,10.10.10.10,8080" Here is how the working ones were added: VBoxManage modifyvm "VM name" --natpf1 "rule1,tcp,127.0.0.1,8181,,80" VBoxManage modifyvm "VM name" --natpf1 "rule2,tcp,127.0.0.1,9191,,9090" And by "non-working", I of course mean not listening (as a prerequisite to forwarding): $ lsof -Pi -n|grep Virtual|grep LISTEN VirtualBo 27050 user 21u IPv4 0x2bbdc68fd363175d 0t0 TCP 127.0.0.1:9191 (LISTEN) VirtualBo 27050 user 22u IPv4 0x2bbdc68fd0e0af75 0t0 TCP 127.0.0.1:8181 (LISTEN) There should be a similar line above but with 127.0.0.1:8282. Just to be clear, this port is listening perfectly fine on the guest itself. And when I remove the guest IP (i.e., clear the 10.10.10.10) the forward works fine, albeit to eth0 (not eth1 where I need it). I can tcpdump and watch the traffic flow back and forth. And yes, I've disabled iptables entirely while testing -- it's not getting blocked anywhere on the guest. As VirtualBox writes in their documentation, you are required to specify the guest IP if it's static (makes sense, no DHCP record it keeps): "If for some reason the guest uses a static assigned IP address not leased from the built-in DHCP server, it is required to specify the guest IP when registering the forwarding rule:". However, doing so (as I need to), seems to break the port forward with nary a report in any log file I can find. (I've reviewed everything in ~/Library/VirtualBox/). Other notes: While I used the above command to add the third rule, I've also verified it showed up correctly in GUI and then removed/re-added from there just to make sure). This forum link -- while very dated -- looks somewhat related in that a port forward to a static IP was not appearing (perhaps they think due to lack of gratuitous arp being sent for host to know IP is there/avail?). Anyway, what gives? Is this still buggy? Any suggestions? If not, easy enough workarounds? What's interesting is that this works perfectly fine on another user's Mac, however he's running a slightly older version (4.3.6 v. 4.3.12).

• I'm trying to setup Xvfb to run an GUI app on a remote server with no display

  - by jz87

  I have a 3rd party java app that I need to run on a remote server. Unfortunately, the app is designed for the desktop and assumes a GUI is available. The thing is I would like to leave this app running on the remote server without having to tie up my desktop machine with a persistent VNC connection to the remote machine. I'm trying to setup Xvfb on the remote machine so emulate a graphical environment, connect to the remote machine via VNC to launch the app and configure parameters and then log off and let it run. Here's what I have so far: I have ubuntu 11.04 server apt-get install xvfb apt-get install fluxbox apt-get install x11vnc Xvfb :1 -screen 0 1024x768x16 & fluxbox & At this point I run into a problem because it gives a very undescriptive error: Cannot connect to server. How do I know if the server is running and that it's running properly?

• Transparent, unicode X terminal not tied to a Desktop Environment?

  - by jamuraa

  I've been looking for this for a while now and I just haven't been able to find one. The last few that I used were: aterm - this one was fast and had good transparency support, but it doesn't support Unicode at all as far as I can tell. The dependency graph is also reasonable. gnome-terminal - was good, and had good transparency support plus unicode, but it pulls in about everything in gnome, and I don't use anything else in gnome. It was also somewhat slow (noticable lag in updating at times) and wouldn't use fonts that I wanted. Eterm - same thing as aterm, good dependencies and transparency but no unicode. Does anyone have suggestions, or will I be stuck with gnome-terminal's dependencies and slowness?

• Forwarding all mail to a single dev box on IIS via virtual SMTP

  - by Greg R

  I am trying to set up a development environment for our web server. I would like all emails that are relayed by the server go to a specific mailbox, regardless of who they were sent to. For example, some application on the server sends an email to [email protected]. I want that email to go to [email protected]. Is that possible to do with IIS/Virtual SMTP? Is there some other way of doing this? I don't have exchange server running, if that makes a difference. Any help would be greatly appreciated. Thanks a lot!

• SSH port forwarding through Windows machine

  - by Leonardo Ramé

  is it possible to connect to an SSH server only accessible from inside a network, using a Windows machine without SSH as a gateway?. Let me clarify my question with a sketch: Me (Linux machine)--- WIN (Windows without SSHD)---LIN (Linux with SSHD). Machine Me, is the PC I'm using to connect to LIN through WIN. WIN is accessible from the outside, it has an RDESKTOP port open, and LIN is only accessible from inside the network. Hope you understand the question.

Please further all communication to this email". Using Outlook as my email client, how can I work this out?

• forwarding packets from wireless nic wlan0 to another Wireless nic wlan1

  - by user179759

  I have two wireless interfaces wlan0, wlan1 I want wlan0 to be connected to the internet via a wireless router and I want wlan1 to be in AP mode acting as a router to give internet access to whoever connectes to it. So basically all packets coming through wlan1 should be forwarded to wlan0 = Router = Internet. That's including DNS/DHCP/etc.. [A]~~~~~(Wi-Fi)~~~~~~v [B]~~~~~(Wi-Fi)~~~> [me] ~~~~(Wi-Fi)~~~~~>[AP/Router]------->[internet] [C]~~~~~(Wi-Fi)~~~~~~^ Any idea how can I do this? ps: I tried using bridges but I always get 'operation not supported' using the brctl tool.

• Gre Tunnel Cisco Linux traffic forwarding

  - by mezgani

  I setup a gre tunnel a cisco router and a Linux machine, the tunnel interface in the Linux box named pic. Well i have to forward traffic coming from cisco through the Linux box. the rules i've set in the Linux box is described as follow: echo "1" /proc/sys/net/ipv4/ip_forward iptables -A INPUT -p 47 -j ACCEPT iptables -A FORWARD -i ppp0 -j ACCEPT iptables -A FORWARD -i pic -o ppp0 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A FORWARD -i ppp0 -o pic -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE I see the traffic coming from tunnel and forwarded to internet but no reply from sent packet. May i miss something like a routing rule.

• IIS - Forwarding requests to a folder to another port

  - by user1231958

  Context I currently installed Glassfish 3 in a server that currently holds ASP and PHP inside Internet Information Server 7 so we can start moving to a new system architecture (the information system is being remade). Obviously, Glassfish uses another port and without too much configuration (all I had to do is to install it) it worked. If I write www.domain.com:8080, the person will be redirected to the Glassfish server. Issue Obviously I don't want the person to write the port! I also believe it might also hold some security issues. Requirement I need the server to take an address of the form www.domain.com/gf or new.domain.com or something alike, and when it receives such a request, "redirect" (masking the URL) the user to the Glassfish website (www.domain.com:8080). Thank you beforehand!

• Need help connecting to NAS externally-port forwarding and DDNS newbie

  - by Joel

  Hi folks, I just picked up a synology NAS, and I'm loving it for internal use, but I want to be able to access the NAS externally-both from my iPhone (3G) and from the net. I have a Linksys WRT54G-TM router. My first question is whether I have set up the dyndns correctly. On my computer that is on my network, if I put in mydomain.dyndns.org, I am taken to a password popup and when I enter my router login and password, my router admin page opens up. On the same computer, I get the same results if I use my external IP address, and if I use my internal IP 192.168.0.1 So that is all as expected. However, when I go to my iphone and turn off wifi, and try to connect with 3g to the external IP or the dnydns domain, I just get an error "Safari could not open the page because the server stopped responding". What's up?

• iptables forwarding between two interface

  - by broody

  So I have a linux box with two wireless interfaces, one is a station and the other an AP. wlan0 (station) - Connected to the internet connection wlan1 (AP) - Other clients connect to it. I would like for clients connected to wlan1 to be able to access the internet on wlan0. And I'd like to do this with iptables as my kernel doesn't have bridging support... Here's what I've tried so far with iptables but it's not working: iptables -A FORWARD -i wlan0 -o wlan1 -j ACCEPT iptables -A FORWARD -i wlan1 -o wlan0 -j ACCEPT I'd appreciate any help.

• Cisco ASA not forwarding traffic from one interface to another

  - by Antoine Benkemoun

  Hello ServerFault, I am needing help in the configuration process of my Cisco ASA 5510. I have set up 4 Cisco ASA interconnected together via a big LAN. Each Cisco ASA has 3 or 4 LANs attached to them. The IP routing part is taken care of by OSPF. My problem is on another level. A computer connected to one of the LANs attached to an ASA has no problem communicating with the outside world. The outside world being anything "after" the ASA. My problem is that I am completely unable to have them communicate with another LAN connected to the same ASA. To rephrase this, I am unable to send traffic from one interface of a given ASA to another interface of the same ASA. My configuration is the following : ! hostname Fuji ! interface Ethernet0/0 speed 100 duplex full nameif outside security-level 0 ip address 10.0.0.2 255.255.255.0 no shutdown ! interface Ethernet0/1 speed 100 duplex full nameif cs4 no shutdown security-level 100 ip address 10.1.4.1 255.255.255.0 ! interface Ethernet0/2 speed 100 duplex full no shutdown ! interface Ethernet0/2.15 vlan 15 nameif cs5 security-level 100 ip address 10.1.5.1 255.255.255.0 ! interface Ethernet0/2.16 vlan 16 nameif cs6 security-level 100 ip address 10.1.6.1 255.255.255.0 ! interface Management0/0 speed 100 duplex full nameif management security-level 100 ip address 10.6.0.252 255.255.255.0 ! access-list nat_cs4 extended permit ip 10.1.4.0 255.255.255.0 any access-list acl_cs4 extended permit ip 10.1.4.0 255.255.255.0 any access-list nat_cs5 extended permit ip 10.1.5.0 255.255.255.0 any access-list acl_cs5 extended permit ip 10.1.5.0 255.255.255.0 any access-list nat_cs6 extended permit ip 10.1.6.0 255.255.255.0 any access-list acl_cs6 extended permit ip 10.1.6.0 255.255.255.0 any ! access-list nat_outside extended permit ip any any access-list acl_outside extended permit ip any 10.1.4.0 255.255.255.0 access-list acl_outside extended permit ip any 10.1.5.0 255.255.255.0 access-list acl_outside extended permit ip any 10.1.6.0 255.255.255.0 ! nat (outside) 0 access-list nat_outside nat (cs4) 0 access-list nat_cs4 nat (cs5) 0 access-list nat_cs5 nat (cs6) 0 access-list nat_cs6 ! static (outside,cs4) 0.0.0.0 0.0.0.0 netmask 0.0.0.0 static (outside,cs5) 0.0.0.0 0.0.0.0 netmask 0.0.0.0 static (outside,cs6) 0.0.0.0 0.0.0.0 netmask 0.0.0.0 ! static (cs4,outside) 10.1.4.0 10.1.4.0 netmask 255.255.255.0 static (cs4,cs5) 10.1.4.0 10.1.4.0 netmask 255.255.255.0 static (cs4,cs6) 10.1.4.0 10.1.4.0 netmask 255.255.255.0 ! static (cs5,outside) 10.1.5.0 10.1.5.0 netmask 255.255.255.0 static (cs5,cs4) 10.1.5.0 10.1.5.0 netmask 255.255.255.0 static (cs5,cs6) 10.1.5.0 10.1.5.0 netmask 255.255.255.0 ! static (cs6,outside) 10.1.6.0 10.1.6.0 netmask 255.255.255.0 static (cs6,cs4) 10.1.6.0 10.1.6.0 netmask 255.255.255.0 static (cs6,cs5) 10.1.6.0 10.1.6.0 netmask 255.255.255.0 ! access-group acl_outside in interface outside access-group acl_cs4 in interface cs4 access-group acl_cs5 in interface cs5 access-group acl_cs6 in interface cs6 ! router ospf 1 network 10.0.0.0 255.255.255.0 area 1 network 10.1.4.0 255.255.255.0 area 1 network 10.1.5.0 255.255.255.0 area 1 network 10.1.6.0 255.255.255.0 area 1 log-adj-changes ! There is nothing really complicated in this configuration. It just NATs from one interface to another and that's it. I have tried enabling same-security-traffic permit inter-interface but that doesn't help. I therefore must be missing something a little bit more complicated. Does anyone know why I cannot foward traffic from one interface to another ? Thank you in advance for your help, Antoine

• iptables port forwarding works only for localhost

  - by Venki

  Below is my iptables config. I used this for my accessing a node js website running in port 9000 through port 80. This works fine only if access the website through local host / loop back. When I try to use the ip of eth0, which is assigned by my router through dcp. this does not work, when I use ip like 192.168.0.103 to access the website. I am not able to figure what is wrong here, Already burnt a day in this, still not able to figure out :( Edit: ( more information) Earlier, I was using this configuration to develop the website, i had configured the domain name to point to 127.0.0.1 in the /etc/hosts file. It was working fine, but now I am trying to deploy the website in a vps with static ip, This configuration does not work with both static IP. # redirect port 80 to port 9000 *nat :PREROUTING ACCEPT [57:3896] :INPUT ACCEPT [0:0] :OUTPUT ACCEPT [4229:289686] :POSTROUTING ACCEPT [4239:290286] -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 9000 -A OUTPUT -d 127.0.0.1/32 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 9000 COMMIT # Allow HTTP and HTTPS connections from anywhere (the normal ports for websites and SSL). -A INPUT -p tcp --dport 80 -j ACCEPT -A INPUT -p tcp --dport 443 -j ACCEPT -A INPUT -p tcp --dport 9000 -j ACCEPT -A INPUT -j REJECT

• SRS / Sender Rewriting when forwarding mail through postfix

  - by Mikeage

  Is there any way to perform SRS, or something similar using Postfix? When I get a mail from [email protected], I forward it (via a catchall) to [email protected], but GMail is checking SPF, and seeing that my server is not authorized to send mail on behalf of example.org. I'd like to rewrite the sender to something@myserver, while leaving the from as [email protected].

• SSL Proxy: Forwarding without the encryption

  - by John

  I have a python application listening on port 9001 for HTTP traffic. I'm trying to configure Apache (or anything, really) to listen on port 443 for HTTPS connections, and then forward the connection, sans encryption, to port 9001 on the same machine. My application would then reply via the proxy, where the encryption would be reapplied, and returned to the client transparently. I'm not doing anything crazy with the site names and SSL certs, I have one public IP, one hostname, and one SSL cert. Stripping the encryption at the proxy doesn't seem to be a common requirement. Is what I'm asking for a normal requirement? Are there other concerns with this sort of configuration?

• TCP/IP Forwarding in Windows Vista and Above

  - by Charles Gargent

  This is the way to do it on XP, but is it possible on Windows Vista and Above? If so how do you detect it? Is there a registry setting for it, or is there com dll or api for it?

• DNS server failure when forwarding

  - by Abraham Katz

  I run Bind 9 on a Ubuntu 12.04 server. I want this server to be a sort of a "wrapper" over my default server, so that it will respond to "domain_name.My_TLD" itself and forward requests to any other request. The server resides in a domain (Disconnected from the internet), so I configured it to zone "company_domain."{ type forward; forwarders { 1.2.3.4 }; #the DC's ip }; When i query it about sommething.company_domain. it sends a query to the DC and gets a response, but it returns "server failure". What can cause that? Cheers, Abraham

• Port Forwarding(?) TD-W8961nd

  - by rich

  I have a bit of a weird internet setup. I am connected via a decent WiFi connection (from work) which I pick up using a Buffalo Airstation Wireless-G box. This simply picks up the signal and gives me 4 ethernet ports to connect to. That's all fine and works as it should. I also have a TP LINK TD-W8961nd router which used to be connected to the Airstation via an ethernet cable so I could essentially have WiFi access in my house. To cut a long story short I can't remember how the hell I got it to work and I can't find the notes I scribbled down on how to do it. I'm pretty sure I need to tell the router what ip to pick up the internet connection from and have the local wifi as a seperate network. How the hell I do that I have no idea right now. Can anyone give me some advice on this? If you need more information ask and I will be able to do so. Cheers in advance. edit I'm in work at the moment so I can't give 100% details but I will be able to later on.

• Recommendation for e-mail forwarding

  - by Paul Mrozowski

  We currently have a provider that we use to primarily forward our e-mails to both a hosted Exchange site and to outside e-mail addresses. We have a large # of forwards set-up (maybe 500). They work fine for us but the bandwidth costs are a getting pretty expensive (approx 80GB in email a month) so we're looking for a less expensive alternative (it costs us nearly $150/mo). I've looked at just hosting this here via a PostFix server and one of the nice front-ends available for it. However, I'm not thrilled with the prospect of being responsible for maintaining yet another server, backups, network connectivity, etc. So I'm leaning towards having this hosted by someone else if possible. Does anyone have any recommendations for hosting providers? Are there some I should stay away from?

  Newbie question: I've got the following set up, the server 2008, the iis and the smtp. I've my mydomain.com set up with DNS pointing to my public ip, www and smtp both.

Primary objective: [email protected] -- [email protected] Secondary objective, for extra love: [email protected] -- [email protected] and [email protected] -- [email protected] Do I need a popserver? Any tutorials people can recommend? Addition: And the MX. I've also pointed the MX record to my ip.

• multiple ssh aliases is selecting wrong user when forwarding

  - by Chris Beck

  I'm following the dual identity procedure for bitbucket: I have 2 bitbucket accounts ccmcbeck and chrisbeck. The former is personal, the latter is work. On my local Mac, I have this in my ~/.ssh/config Host *.work.com User chris ForwardAgent yes IdentityFile ~/.ssh/work_dsa Host bitbucket-personal HostName bitbucket.org User ccmcbeck ForwardAgent no IdentityFile ~/.ssh/bitbucket_ccmcbeck_rsa Host bitbucket-work HostName bitbucket.org User chrisbeck ForwardAgent no IdentityFile ~/.ssh/bitbucket_chrisbeck_rsa On my local Mac I ssh -T all is good, I get: $ ssh -T git@bitbucket-personal logged in as ccmcbeck. $ ssh -T git@bitbucket-work logged in as chrisbeck. On my local Mac, the ssh version is OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 When I ssh foo.work.com to my Linux box, I get: $ ssh-add -l 1024 ... /Users/chris/.ssh/work_dsa (DSA) 2048 ... /Users/chris/.ssh/bitbucket_ccmcbeck_rsa (RSA) 2048 ... /Users/chris/.ssh/bitbucket_chrisbeck_rsa (RSA) On foo.work.com, I also have this in my ~/.ssh/config Host bitbucket-personal HostName bitbucket.org User ccmcbeck ForwardAgent no IdentityFile ~/.ssh/bitbucket_ccmcbeck_rsa Host bitbucket-work HostName bitbucket.org User chrisbeck ForwardAgent no IdentityFile ~/.ssh/bitbucket_chrisbeck_rsa However, on foo.work.com when I ssh -T, it references the wrong User for git@bitbucket-work $ ssh -T git@bitbucket-personal logged in as ccmcbeck. $ ssh -T git@bitbucket-work logged in as ccmcbeck. On foo.work.com, the ssh version is OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 Why is my configuration causing foo.work.com to reference the wrong User?
