I was setting up a new 11.4 system and disabled ip6 as we don't use it. After that I couldn't get X11 forwarding working. After searching around for a while, I found this topic [URL] ssh-x11-forwarding.html which at the end mentions enabling ip6. Magically, after doing that and rebooting I can now do X11 forwarding again. Just seems strange that IP6 is needed for X11 forwarding.

- eth0 private net
- eth1 internet
eth1 is connected to a cable modem and uses dhcp. After migrating to suse-11.2 ip-forwarding (once the system is up and running) is sometimes deactivated and i have no clue why. /etc/syslog.conf has an entry net.ipv4.ip_forwarding = 1
i have modified the SuSE-scripts /sbin/SuSEfirewall /sbin/ifup-dhcp /etc/init.d/SuSEfirewall2_setup to make sure each time my firewall-rules are loaded ip-forwarding is explicitly enabled. This worked perfectly with suse-11.0. Now ip-forwarding is enabled after a system reboot or after one of the above scripts is called, but somewhere somehow ip-forwarding is always deactivated and i have no idea how this happens. This may happen after 5 minutes or after 5 hours. As a workaround i created a cronjob running every 5 minutes issuing a sysctl-command to enable ip-forwarding.
I'm running suse 11.1 which is configured as a router. Configured are two DSL connections with static IP's and one LAN connection (3 NIC's all together).
Problem: suse firewall will only port forward connections from one of the DSL connections and not the other.
Because I'm running two DSL connections is there something special I have to turn on/enable on the firewall?
I used to have Opensuse 11.0 and Vuze 4.0.2 and both were working great. Recently I upgraded to OpenSuse 11.3 and installed Vuze 4.5.10. I did not change any configuration in the ADSL router but now I could not get the smiley icon to go green. I followed all the steps given here: A Quick Bittorrent Guide (with screenshots). It doesn't work. so I modified FW_ROUTE and FW_MASQUERADE to yes in /etc/sysconfig/SuSefirewall2. That also does not work. What did I miss here? My ADSL router is DSL-2640T.

I'm facing a challenge in setting up a simple routing between 2 networks. The situation is as follows.We're using 2 networks, 1 that handles all the office traffic and 1 that is used for storage traffic to the NAS. I'm trying to setup a simple router that will forward requests from the office LAN to the storage one, so people can access the NAS interface on the storage LAN.
So, I have a CentOS 5.5 box, connected to both networks that should handle this job. The office LAN is 172.29.38.0/24 and the storage LAN 10.1.2.0/24. IP adrresses of the linux box are 172.29.38.98 (eth0) and 10.1.2.98 (eth1).First I started by enabling IP-forwarding in the kernel:
Code:
# cat /proc/sys/net/ipv4/ip_forward
Below is a copy of the iptables in use:
Code:
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]

It just never seems to get to the machine on the other side. I've verified that I can access both networks from the router and I can ping the router from my client.
I have a question about port forwarding. I have an internal Red Hat server and I would like to use it as a central connection point to some back end servers. This is not an internet router setup. I was thinking I could use iptables and do port forwarding similar to an internet router but internal to internal.
Basically I would like to take any connections to port 22 on server1 interface eth0 and forward them out of interface eth1 to server2 port 22.I am finding a lot of information on port forwarding, but it is all based on using an internet router that is passing through to an internal server. I need to know how to configure a basic linux setup with no existing iptables entries so that I can do this within an existing network.Also, if there is a better or easier approach I would appreciate any direction. I don't want to do this through an SSH tunnel.I know to start I need the following to enable forwarding in the kernel and a firewall PREROUTING rule.
I have an OpenVPN(10.04.2 LTS) server running in bridge (TAP) mode. Its sitting behind a router and then a cable modem. The VPN works perfectly but I have a security concern. In order to allow the VPN clients to connect to the internet, I had to enable IPv4 forwarding on the server. Is this is a security hole? Can a hacker access my servers connection from the internet (without authenticating with OpenVPN) and access my network. Can someone use Ipv4 forwarding to access my LAN network from the WAN
I used this command to enable ipv4 forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward
Without IPv4 forwarding my VPN clients can only access my LAN and router, but they cannot reach my modem or the internet.

I am setting up Apache (Fedora 12) inside my home network. From inside my home network I access it without any problem. I need to set it up to access it from internet. I have the following questions. Here is temporary setup for testing purpose.
Internet-->ADSL modem (SEIMENS Speed Stream 4200)---> Apache (Fedora 12)
1. Do I have to do any kind of ports forwarding on ADSL modem. (There is no option to do port forwarding on Modem) May be I need different Model of Modem??
2. I tired to Ping my real IP for modem form another computer from internet. I am even unable to PING the ADSL 's real IP. Why it is that?

View 1 Replies View RelatedInitially i was on kubuntu 10.10 with kde 4.5.x and i realized that animations throughout kde stunk. For example, the kickoff menu would raise and lower very jerky. So thinking this was a kubuntu or even a kde 4.5.x problem, I made a switch to opensuse 11.3 and kde 4.4.x. After install i noticed that all animations, including the menu raising and lowering, where very smooth and crisp (like they should be). I later realized I wasn't even using all my hardware's power so I put my two gtx 460s in SLI=auto. After a reboot I realized that once again all animations got jerky again . This leads me to believe,and for good reason, that kde's visual performance is degraded with SLI enabled.
Ps: installed kde 4.5.2 and still same problem
I have a recently installed openSUSE 11.2. I am attempting to install from the openSUSE source repository with the Software Manager. By default this repository is not enabled, so I opened the configuration window and enabled it. Although the repository is enabled, Software Manager does not populate the Package Listing panel with available package and hence I cannot install source RPM packages.
I can, however, access the repository via HTTP and download packages although I don't yet know how to install individual packages. The repository URL as preconfigured in Software Manager is: Index of /source/distribution/11.2/repo/oss Again, Software Manager seems not to access this repository but I can access it directly via HTTP.
As it stands I have a small home network operating behind my modem/router. Some of the ports on this are forwarded to my PS3 for gaming but I was looking at forward some for my file server.
At the moment I've forwarded port xxx22 to port 22 on my server for SSH for instance. ANd similarly 21 for FTP (although it doesnt seem to want to connect for any more than a few seconds using that). What I was thinking of doing was placing a small website for a handful of ppl to use on the server too and port forward again - xxx80 to 80. It works just fine but I'm a little concerned on the security front.
As I've moved the port to something different from the outside world I'm presuming I will have already cut the potential for malicious folks to wander in but is there anything else I should be doing? At the moment there's no firewall operating on the server, usually as its hidden behind the modem/router. But if I open this thign up more permanently what should I be doing? I've read a few articles on it but I'm always left with the overwhelming thought of "Thats if theres no firewall in my router" as they just seem to do the same.
