• Can I set up two NICs bridged together and still SSH into the bridging machine?

  - by squinlan

  I have a ubuntu box setup with two NICs. I can bridge them together just fine, but I haven't been able to setup a way to SSH into the box once the connections are bridged together. Here's my /etc/network/interfaces: auto lo iface lo inet loopback auto eth1 iface eth1 inet manual auto eth0 iface eth0 inet manual auto br0 iface br0 inet static address 192.168.33.213 netmask 255.255.255.0 gateway 192.168.33.1 bridge_ports eth0 eth1 bridge_stp off bridge_fd 0 bridge_maxwait 0 This works just fine for bridging, but I'm not able to SSH into the box. I tried setting up another interface on one of the NICs: auto eth0:1 iface eth0:1 inet static address 192.168.33.215 netmask 255.255.255.0 gateway 192.168.33.1 But this really didn't help. Is it possible to ssh into a machine that has all of its NICs bridged? If it is, how?

• Configure server on network to analyze traffic

  - by Strajan Sebastian

  I have the following network: http://i.stack.imgur.com/rapkH.jpg I want to send all the traffic from the devices that connect to the 192.168.0.1 router to the 192.168.10.1 router(and eventually to the Internet), by passing through the server and an additional router. Almost 2 days have passed and I can't figure what is wrong. While searching on the Internet for some similar configuration I found some articles that are somehow related to my needs, but the proposed solutions don't seem to work for me. This is a similar article: iptables forwarding between two interface I done the following steps for the configuration process: Set static IP address 192.168.1.90 for the eth0 on the server from the 192.168.1.1 router Set static IP address 192.168.0.90 for the eth1 on the server from the 192.168.0.1 router Forwarded all the traffic from 192.168.0.1 router to the server on eth1 interface witch seems to be working. The router firmware has some option to redirect all the traffic from all the ports to a specified address. Added the following rules on the server(Only the following, there aren't any additional rules): iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT I also tried changing iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT into iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT but still is not working. After adding the following to enable the packet forwarding for the server that is running CentOS: echo 1 /proc/sys/net/ipv4/ip_forward sysctl -w net.ipv4.ip_forward = 1 After a server restart and extra an extra check to see that all the configuration from above are still available I tried to see again if I can ping from a computer connected to 192.168.0.1/24 LAN the router from 192.168.1.1 but it didn't worked. The server has tshark(console wireshark) installed and I found that while sending a ping from a computer connected to 192.168.0.1 router to 192.168.1.1 the 192.168.0.90(eth1) receives the ping but it doesn't forward it to the eth0 interface as the rule tells: iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT and don't now why this is happening. Questions: The iptables seem that don't work as I am expecting. Is there a need to add in the NAT table from iptables rules to redirect the traffic to the proper location, or is something else wrong with what I've done? I want to use tshark to view the traffic on the server because I think that is the best at doing this. Do you know something better that tshark to capture the traffic and maybe analyze it?

• Postfix - How to process incoming emails?

  - by Borivojevic

  Hello Does anybody know how to process incoming emails for virtual mailboxes in postfix? I am building web application where users add new content by sending emails to application. Email address used for each user is custom (eg. [email protected]) and it is dynamically created as a Postfix virtual mailbox. User needs to be able to send email to his custom mailbox address ([email protected]) and i want to process each incoming email, parse it's contents and populate my database with data from email. I tried using Postfix After Queue filter but what i really wont is to process emails once they are saved in users virtual mailbox folder.

• Why can't we reach some (but not all) external web service via VPN connection?

  - by Paul Haldane

  At work (UK university) we use a set of Windows servers running WS2008R2 and RRAS which offer VPN service to students in our accommodation. We do this to associate the network connections with individuals. Before they've connected to the VPN all they can talk to is the stuff thats needed to setup the VPN and a local web site with documentation on how to connect. Medium term we'll probably replace this but it's what we're using at the moment. VPN on the 2008 servers allocates client a private (10.x) address. Access to external sites is through NAT on the campus routers (same as any other directly connected client on a private address). Non-VPN connections aren't seeing this problem. Older servers run WS 2003 and ISA2004. That setup works but has become unreliable under load. Big difference there was that we were allocating non-RFC1918 addresses to the clients (so no NAT required). Behaviour we're seeing is that once connected to the VPN, clients can reach local web sites (that is sites on the campus network) but only some external sites. It seems (but this may be chance) that the sites we can reach are Google ones (including YouTube). We certainly have trouble reaching Microsoft's Office 365 service (which is a pain because that's where mail for most of our students is). One odd bit of behaviour is that clients can fetch (using wget on a Windows 7 client) http://www.oracle.com/ (which gets a 301 redirect) but hangs when asked to fetch http://www.oracle.com/index.html (which is what the first URL redirects to). Access works reliably if we configure clients to use our local web proxies (Squid). My gut tells me that this is likely to be something in the chain dropping replies either based on HTTP inspection or the IP address in the reply. However I'm puzzled about why we're seeing this with the VPN clients. Plan for tomorrow (when I'm back in the office) is to setup a web server on external connection so that we can monitor behaviour at both ends of the conversation (hoping that the problem manifests itself with our test server). Any suggestions for things we should be looking at?

• Why configuring manual IP do not work for me in DHCP?

  - by user58859

  I have broadband connection in my laptop. It's getting the IP by protocol. configuration is : ip : 192.168.1.2 subnet : 255.255.255.0 gateway : 192.168.1.1 Now I am curious, In IPV4 properties when instead of choosing "Obtain an IP address automatically", I choose "Use the following IP address" and configure everything same, why it do not work? Do DHCP do not work when we configure the IP manually? (operating system : windows-7) EDIT : After configuring the ip manually, when I used ipconfig/all , it's showing dhcp enabled : NO. I am not doing it. Why it got disabled automatically? and how to enable it?

• How to configure OpenVPN server to use custom default gateway?

  - by Arenim

  I have a vpn server at address 10.1.0.2 and the server have another ip in it's network -- 10.0.0.2 in his subnet (it's a tun2socks router). But default server's gateway is NOT 10.0.0.2 (and it's ok) but another external IP. I want all the client's traffic to be forwarded through this ip address -- 10.0.0.2. Here is part of my server's config: dev tap0 server-bridge 10.1.0.1 255.255.255.0 10.1.0.50 10.1.0.100 push "route 10.0.0.0 255.255.255.0" ; now client can ping 10.0.0.2 push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 10.1.0.1" push "dhcp-option WINS 10.1.0.1" in fact i want some like push "redirect-gateway 10.0.0.2" How can I achieve this?

• xenserver: xe command never returns?

  - by ethrbunny

  I'm trying to port a xen server 6.2 pool to a new IP address range. I've got three servers total: 2 currently at their new IP but no longer in the pool and one remaining. I'm trying to set IP address information on the two disconnected ones using the xe command and all of its variants. Oddly enough, it never returns with any values. xe host-list It just sits there until I ctrl-c it. The server is still awake and responding though. I can enter other commands (EG ifconfig) and they work fine. If I enter this same command on the remaining server in the pool it works ok. I've tried restarting the toolstack and even rebooting. No change. What am I doing wrong?

• How to add network printer remotely without knowing the IP?

  - by Steve

  Assume your friend from over 100km away asked you to add a network printer to his computer since you're so tech savvy. How would you add network printer remotely in this case? You would need: 0. Remote connection to your friend's computer 1. Printer IP and brand/model names 2. Respective drivers downloaded either from manufacturer's website or Windows Update driver Question is, how would you find out the IP address of the printer without bothering your friend too much with technical steps? Since your friend isn't as tech savvy as you - they wouldn't know which buttons to press to get IP address.

• Cant connect to home server

  - by user52141

  Trying to figure out what I might be doing wrong. I installed XAMPP - and everything looks fine. If I go to localhost everything comes right up. But when I go to my IP address, I just get a message that the browser could not connect to it. I go into my router and set up port forwarding for port 80 etc, and I even tried putting the server as a DMZ - still nothing. I turned the firewall off to see if that was interfering in some way, then uninstalled it completely for good measure, made no difference. I'm out of ideas.. oh, and yes I have a static IP address.

• ASUS WL-500gP v2 network between two local machines

  - by Epsiloncool

  I have two windows XP machines in my home networks, connected with ASUS WL-500gp V2 which also used as internet router. Problem is: while I have both computers normally goes to internet (used DHCP, static routes is ON, routing table is empty, operation mode is Home Gateway). I see both computers listed on the Network Neighborhood on 1st computer (wired to router), can enter to my own computer, but can not enter to other. I see only one computer (2nd) on the Network Neighborhood on 2nd computer (connected thru Wi-Fi), can enter to itself, getting error when trying to enter 1st computer address in address line (like \My1stComp). What is the problem? I totally crazy founding problem about 3 months.

• Squid 2.7.6 not honoring ACL rules

  - by peppery

  Hello there, I have a /24 block of IP addresses assigned to a single server that I have been attempting to install Squid on an Ubuntu server machine. All of the IP addresses are set up correctly (aliases of eth0) in /etc/networking and work as they should be, using cURL I can specify an interface and it goes out on the correct address as it should be. I would like Squid to take the incoming IP address the request was sourced to and proxy the request out on the same IP (e.g incoming 123.123.123.1:3128 - 123.123.123.1, .2 - .2, etc) and have set up these ACL rules in /etc/squid.conf acl ip1 myip x.x.x.1 tcp_outgoing_address x.x.x.1 ip1 acl ip2 myip x.x.x.2 tcp_outgoing_address x.x.x.2 ip2 acl ip3 myip x.x.x.3 tcp_outgoing_address x.x.x.3 ip3 and so on, as this seems to be the only way to do what I want (from research). However, after much frustration, Squid seems to be ignoring these rules and sending requests out on the default interface. Does anybody have any suggestions? Thanks.

• How to forward traffic using iptables rules?

  - by ProbablePattern

  I am new to iptables and I have been doing Google searches for a few days now without finding a good solution to this problem. I have computer A with a public ip address (say 192.0.2.1) that can access the Internet unrestricted. I have another computer B with a private ip address (192.168.1.1) that can only access computer A. How do I use iptables to forward network traffic from B through A to the Internet? I need to use http, ftp, and https in order to use apt-get with sudo. Both computers run Ubuntu linux. I have tried using Squid but I think it is far too complicated for what I need to do.

• Cannot access internal network on OSX 10.6.6

  - by cabuki

  Last week, I began having trouble connecting to our internal web servers. Usually, a refresh would take care of it or switching to a different wireless network, but as of yesterday, this wasn't enough. We have an internal DNS server using dnsmasq and a private internal host name (us.lcl). Once I started having more issues with the names not resolving, I tried pinging the server. Using the internal host name (s1.us.lcl), it failed. I tried using the IP address, but that also failed. I have no problems accessing external sites with the exception of it being a bit slower than normal. A reboot yesterday at lunch time after following the instructions here seemed to fix the issue, but when I came into the office this morning, it had stopped working. As of this posting, I cannot ping, ssh or access the web server using the internal host name or ip address. I'm the only one running 10.6 in my office and none of my colleagues has this issue.

• Mirrored servers in data centers nationwide -- how?

  - by Sysadmin Evstar

  Mirrored servers in data centers nationwide -- how? I flunked my IT interview by getting this question wrong. I thought that in the various metropolitan areas, an "http://google.com" request goes to the ISP's DNS server, which somehow returns an IP address for one of several geographically-nearby http servers, and then something internally rolls over to the next available local Google server. But then, I could not explain where the table of available local Google servers is actually cached, or the details of the IP address rollover. Or how they could manually take some server out of the rotation, from anywhere. So, what should I be reading now so I can ace this question next time? Also, what daemons run on these machines 24/7 to keep all those mirrored database disks synchronized?

• Changed domain A records for new static ip, but no mail

  - by Tim the Enchanter

  We have recently changed our ISP, I have changed the mail and mailserver DNS A records for our domain name to point to the new external static IP address assigned to the router by the new ISP (the MX record points to mail.<mydomain> as always) but I am not getting any email (though sending email works). Do I just have to wait will the change propagates? I am slightly concerned because I can connect to the web email service made visible through the new router which suggests that the mail.<mydomain> static I.P. address change has happened. Have I missed something?

• Do emails from ShoppyBag contain virus or malware ?

  - by Sysadmin Evstar

  I am curious -- when the ShoppyBag virus gets sent to you from a compromised "friend", inside the message is a secret one-pixel IMG unique to your email address --- and when your GMail message pulls up the message and the IMG is loaded from their server and displayed, their server knows you have read the message. At that moment, does it then grab your Gmail address book, the Flash Cookies, and all the Local Shared Objects it can find, i.e. at the instant you READ the message with the ShoppyBag virus, is it already too late? Do you have to Delete it to the Trash , then Delete Forever it , without reading it to be safe?

• /etc/hosts in Windows 8.1 doesnt work like in Windows 7 [on hold]

  - by user225438

  Last time when i installed Win7, i configured it to block some netbios names in LAN with hosts file. Something like this: 192.168.0.10 computer_name 192.168.0.10 computer_IP where 192.168.0.10 some ip-address in network, where user need to login to access it. So, when user trying to access computer_name via \\computer_name, he will redirect to 192.168.0.10 rather then going to computer_name. In Windows 8.1 I can't do this trick. I tried to disable Windows Defender, flushed DNS, nbtstat -R. Nothing works. When I pinging computer_name, IP address returning 192.168.0.10, but when I accessing it via explorer (\\computer_name\d$), it opening computer partitions. In Win7, when I trying to access \\computer_name, its trying to open 192.168.0.10 one. Maybe its not the best solution to do this, but it works in Windows 7.

• postfix + mysql, user unknown

  - by stoned

  I have installed postfix with dovecot and postfix admin and all seemed well at the beginning. I can log in with thunderbird and check the mailboxes (all empty now) and TRY to send mail, even TLS works. The problem comes when I try to send mail. This is the output of mail.log when I try to send mail from an address to the same address: Nov 23 16:41:55 mailforge postfix/local[6322]: 297792467C: to=, relay=local, delay=0.01, delays=0/0/0/0.01, dsn=5.1.1, status=bounced (unknown user: "test") Nov 23 16:41:55 mailforge postfix/qmgr[6293]: 297792467C: removed To me it looks like as if postfix tries to look for the user "test" while in the mysql database users are named as [email protected] . Where should I change this behaviour?

  So I have a info.php page which is located on the folder /var/www/nginx-default, however when I go to my ip address/info.php, it always redirects me to this site: http://www.iana.org/domains/example/ is this because I have a virtual host that I called example?

• Access logs show someone "GET"ing a random ip, why does this return 200?

  - by Wilduck

  I have a small linux box set up with Apache as a way to teach myself Apache. I've set up port forwarding on my router so it's accessible from the outside world, and I've gotten a few strange requests for pages that don't exist from an ip address in China. Looking at my access_log shows that most of these return 404 errors, which I'm guessing is a good thing. However, there is one request that looks like this: 58.218.204.110 - - [25/Dec/2010:19:05:25 -600] "GET http://173.201.161.57/ HTTP/1.1" 200 3895 I'm curious what this request means... That ip address is unconnected to my server as far as I know, and visiting it simply tells me information about my uid. So, my questions are: How is it that this request is showing up in my access_log, why is it returning 200, and is this a bad thing (do I need to set up more security)?

• Set up homeserver with single IP to host multiple sites on Ubuntu [closed]

  - by Ortix92

  I am trying to set up my homeserver so it can function as a regular server one would rent. I am running Ubuntu 12.04 LTS with openpanel. I have a single static IP address. I am used to having two addresses and pointing them to NS1.domain.tld and NS2.domain.tld and setting up the propper DNS records. I would also like to mention I am somewhat new to DNS zones. Either way, how would I go about setting this up correctly (in openpanel) with just a single IP address if possible at all? I have also read about free solutions online, but I would like to keep everything secure and private so other people can't peer into my data somehow. Thanks!
