  • Routing all data through an VPN tunnel with ppp

    - by Oliver
    I'm trying to create a VPN tunnel that forwards all data from the local machine to the VPN server. I'm using ppp-2.4.5 for this with the following configuration: pty "pptp <VPNServer> --nolaunchpppd" name <my login name> remotename PPTP usepeerdns require-mppe-128 file /etc/ppp/options.pptp persist maxfail 0 holdoff 5 I have a script in if-up.d with the following content: route del default eth0 route add default dev ppp0 Before starting the VPN tunnel my routing looks like: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 2 0 0 eth0 127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo 192.168.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 After starting the tunnel (via pon) it looks like: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0 12.34.56.1 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo 192.168.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 Now the problem is, that the VPN tunnel seems to be looped into itself. If I run ifconfig after a few seconds without any traffic: eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.0.10 netmask 255.255.0.0 broadcast 192.168.255.255 ether 00:01:2e:2f:ff:35 txqueuelen 1000 (Ethernet) RX packets 39931 bytes 6784614 (6.4 MiB) RX errors 0 dropped 90 overruns 0 frame 0 TX packets 34980 bytes 7633181 (7.2 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 20 memory 0xfbdc0000-fbde0000 ppp0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1496 inet 12.34.56.78 netmask 255.255.255.255 destination 12.34.56.1 ppp txqueuelen 3 (Point-to-Point Protocol) RX packets 7 bytes 94 (94.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 782863 bytes 349257986 (333.0 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 It states that already over 300 MiB have been send, ppp0 is only online since a few seconds and the connection isn't working anyway. Can someone please help me to fix the routing table, so that the traffic from ppp0 is not send again through ppp0 but instead goes to the remote server?

  • Is it worth the effort to block failed login attempts

    - by dunxd
    Is it worthwhile running fail2ban, sshdfilter or similar tools, which blacklist IP addresses which attempt and fail to login? I've seen it argued that this is security theatre on a "properly secured" server. However, I feel that it probably makes script kiddies move on to the next server in their list. Let's say that my server is "properly secured" and I am not worried that a brute force attack will actually succeed - are these tools simply keeping my logfiles clean, or am I getting any worthwhile benefit in blocking brute force attack attempts?

  • Build a server in KVM linux

    - by Lai Yu-Hsuan
    I owned a linux server. Now there are several users want to build web services on it, but they require different enviroments. For convenience I give a KVM virtual machine root permission to each user. But obviously the linux server has only one IP. How can I deliver the external requests to corresponding virtual machine? (I expect it's somewhat complicated. If so I want at least some docs/websites I can start reading.)

  • routing through multiple subinterfaces in debian

    - by Kstro21
    my question is as simple as the title, i have a debian 6 , 2 NICs, 3 different subnets in a single interface, just like this: auto eth0 iface eth0 inet static address 192.168.106.254 netmask 255.255.255.0 auto eth0:0 iface eth0:0 inet static address 172.19.221.81 netmask 255.255.255.248 auto eth0:1 iface eth0:1 inet static address 192.168.254.1 netmask 255.255.255.248 auto eth1 iface eth1 inet static address 172.19.216.3 netmask 255.255.255.0 gateway 172.19.216.13 eth0 is conected to a swith with 3 differents vlans, eth1 is conected to a router. No iptables DROP, so, all traffic is allowed. Now, passing the traffic through eth0 is OK, passing the traffic through eth0:0 is OK, but, passing the traffic through eth0:1 is not working, i can ping the ip address of that sub interface from a pc where this ip is the default gateway, but can't get to servers in the subnet of the eth1 interface, the traffic is not passing, even when i set the iptables to log all the traffic in the FORWARD chain and i can see the traffic there, but, the traffic is not really passing. And the funny is i can do any the other way around, i mean, passing from eth1 to eth0:1, RDP, telnet, ping, etc, doing some work with the iptable, i manage to pass some traffic from eth0:1 to eth1, the iptables look like this: iptables -t nat PREROUTING -d 192.168.254.1/32 -p tcp -m multiport --dports 25,110,5269 -j DNAT --to-destination 172.19.216.1 iptables -t nat PREROUTING -d 192.168.254.1/32 -p udp -m udp --dport 53 -j DNAT --to-destination 172.19.216.9 iptables -t nat PREROUTING -d 192.168.254.1/32 -p tcp -m tcp --dport 21 -j DNAT --to-destination 172.19.216.11 iptables -t nat POSTROUTING -s 172.19.216.0/24 -d 172.19.221.80/29 -j SNAT --to-source 172.19.221.81 iptables -t nat POSTROUTING -s 172.19.216.0/24 -d 192.168.254.0/29 -j SNAT --to-source 192.168.254.1 iptables -t nat POSTROUTING -s 172.19.216.0/24 -o eth0 -j SNAT --to-source 192.168.106.254 dong this is working, but,it is really a headache have to map each port with the server, imagine if i move the service from server, so, now i have doubts: can debian route through multiple subinterfaces?? exist a limit for this?? if not, what i'm doing wrong when i have the same setup with other subnets and it is working ok?? without the iptables rules in the nat, it doesn't work thanks and i hope good comments/answers

  • Multiple websites each with an SSL certificate of its own

    - by ServerDown
    Hi, We run cent os, plesk with apache and php, mysql. There are around 25 sites and each of them need an SSL certificate now. The host cannot have more than 16 IPs on the same server. Is it possible to have all these sites use just one IP address and have SSL certificate setup for each site? If yes, please let me know how I can set this up. Thanks

  • Primary/secondary ethernet interfaces via NetworkManager in Ubuntu 9.10

    - by Josh
    I have an Ubuntu 9.10 machine with three ethernet interfaces, eth0, eth1 and eth2. eth2 is connected to a private network. eth0 and eth2 are connected to two different LANs. Either one will provide access to the internet. All three networks have DHCP servers. Using Ubuntu's the default settings (And Gnome), when I boot up all the interfaces are active and my system gets three IP addresses. However any attempt to access the internet results in connection timeouts and other weirdness. I suspect that traffic is going out on one NIC (like eth0) and coming back in on another (like eth1). I'm not sure what's going on. The only way I can access the internet at the moment is to bring two of the devices down with ifdown. How can I configure eth0 as my primary interface so all trafic goes out by default on that interface, while keeping the other two active? Also, I want to make sure Avahi broadcasts properly on all three IPs so that the computers on the LAN of eth1 can still connect to myHostname.local... EDIT: Here's my routing table: Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 172.16.151.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2 172.16.30.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.1.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 172.16.30.2 0.0.0.0 UG 0 0 0 eth0 0.0.0.0 10.1.0.1 0.0.0.0 UG 0 0 0 eth1 I want the 172.16.30.2 network to be the primary one and the 10.1.0.0 network to be the secondary one. EDIT2: My nameservers are also incorrect. It seems like Ubuntu is bringing the networks up in order, eth0, then 1, then 2, and the DHCP information from eth1 is overriding eth0, and eth2 is overriding eth1. How can I reverse this so the DHCP information from eth0 is the "master"? EDIT3: This seems to be an issue with Gnome's NetworkManager.

  • Divide a network into two subnets of equal size

    - by kylex
    I have been given the following IP 192.168.14.137/25 and asked to divide the network into 2. This is what I've come up with: The subnet mask is therefore 255.255.255.128 The network address is 192.168.14.128 There are a total of 128 available addresses (including the network address and broadcast address) To divide the network we create to subnets: 192.168.14.128/26 192.168.14.192/26 This will have a subnet mask of 255.255.255.192 Am I missing anything, or is this correct?

  • My network drive disappears from Mac OS Finder

    - by Mariusz
    I have recently bought a Netgear WNDR3800 router to use it in my home network. But just the same day I installed it, I noticed a strange behaviour of Finder and iTunes. Let me explain it further. There is a Synology DS111 NAS attached to that router and two Macs with Mac OS X Lion. One of them is connected by a cable and the second one wirelessly. Before I changed my router to the new one I mentioned above, Finder always used to display my NAS on its sidebar. So I could just click its network name to access shared folders existing on it. But after I installed WNDR3800, I can no longer access the NAS that way. It is no longer displayed. I always have to mount it manually by typing its IP address using the Finder's 'connect to server' option. The same NAS supports TimeMachine backups and has an inbuilt DLNA server. And the same situation here. I can't perform a backup because my NAS is no longer accessible in TimeMachine preferences. iTunes does not display it as well (as a multimedia server) even though it used to before I installed that router. What's important, everything works fine for a couple of minutes after I restart the router or the NAS. Or even when I change the NAS's IP address it becomes accessible again in Finder, TimeMachine and iTunes, but only for some time. Both the Mac computers I mentioned behave the same way. And all those issues have been taking place sice I installed that new router. Before I did that, everything had worked fine. My old router was Netgear WGR614v10. Would you be so kind to tell me what you think could possibly be the reason of that behaviour? What settings of the router should I look closer at? I'm not a network specialist, but is it possible that some network packets are blocked for some reason? I will be grateful for any clues you give me. Thank you.

  • How to test if DNS information has propagated?

    - by Andrew
    I set up a new DNS entry for one of my subdomains (I haven't set up any Apache virtual hosts or anything like that yet). How can I check that the DNS information has propagated? I assumed that I could simply ping my.subdomain.com and assume that if it could resolve, it would show the IP address I specified in the A record. However, I don't know if I am assuming correctly. What is the best way to check this information?

  • Can someone access my locally ran website even if I haven't specified any port forwarding?

    - by user701510
    I am using Xampp so I can test my web application directly on my own computer. I am concerned that someone can access my Xampp site since I am still connected to the internet. However, I have NOT explicitly enabled any port forwarding with respect to my Xampp site in my router firewall settings. Furthermore, I am using a dynamic ip address. Given the factors already stated, can someone from outside my local network still access my locally ran website?

  • Routing table with two NIC adapters in libvirt/KVM

    - by lzap
    I created a virtual NAT network (192.168.100.0/24 network) in my libvirt and new guest with two interfaces - one in this network, one as bridged (10.34.1.0/24 network) to the local LAN. The reason for that is I need to have my own virtual network for my DHCP/TFTP/DNS testing and still want to access my guest externally from my LAN. On both networks I have working DHCP, both giving them IP addresses. When I setup NAT port forwarding (e.g. for ssh), I can connect to the eth0 (virtual network), everything is fine. But when I try to access the eth1 via bridged interface, I have no response. I guess I have problem with my routing table - outgoing packets are routed to the virtual NAT network (which has access to the machine I am connecting from - I can ping it). But I am not sure if this setup is correct. I think I need to add something to my routing table. # ifconfig eth0 Link encap:Ethernet HWaddr 52:54:00:B4:A7:5F inet addr:192.168.100.14 Bcast:192.168.100.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:feb4:a75f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:16468 errors:0 dropped:27 overruns:0 frame:0 TX packets:6081 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:22066140 (21.0 MiB) TX bytes:483249 (471.9 KiB) Interrupt:11 Base address:0x2000 eth1 Link encap:Ethernet HWaddr 52:54:00:DE:16:21 inet addr:10.34.1.111 Bcast:10.34.1.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:fede:1621/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:34 errors:0 dropped:0 overruns:0 frame:0 TX packets:189 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4911 (4.7 KiB) TX bytes:9 # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.34.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 1002 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1003 0 0 eth1 0.0.0.0 192.168.100.1 0.0.0.0 UG 0 0 0 eth0 Network I am trying to connect from is different than network the hypervisor is connected to: 10.36.0.0.

I thought setting correct interface would be sufficient. What is needed to get my packets coming through?

When I enter the exact ip of the polling server it works (192.168.3.180) It even works if I enter the whole netmask (255.255.252.0) Anyhow it should work according to documentation. Did I do anything wrong?
