Just wonder is there any command that blocks all connections?
I am aware about RedHat #sudo /sbin/services iptables panic
and wonder is there something with similar effect in opensuse?
For some reason my FTP packets are blocked by iptables even though I thought I allowed them through
My syslog errors are along this line:
And my iptables ruleset:
I've just started using ufw with the frontend gufw. I've configured it like this:
Accept everything in and out as default Block incoming FTP connections from a certain IPv4 address (brute-force for days)
Today I noticed that IPv6 connections don't work anymore. The connection to two hosts (IPv6 only) times out. As soon as I disable ufw entirely, the connections work again. The host I want to connect to is:
2001:638:a00:f00b:200:1cff:fedb:d38f port 7337
2001:638:a00:f00b:a00:6ff:fe07:cda2 port 7337
These are small telnet servers that print out a number (temperature nearby) and close again. I'm logging those values in a database.
Is ufw not IPv6-capable and blocks things it's not supposed to?
Update: ufw seems complete garbage to me... You can't even configure it while it's disabled! How am I supposed to safely activate it when the first thing it does is blocking all communications? I can't even configure it to let me in before I configure it to keep me out... And then, even if I explicitly let it pass port 7337, it still blocks it through IPv6.
I have a fresh install of SuSE 11.2. I have installed Communigate Pro (Email server) and Webmin. From my workstation (on the same LAN), I can access the web interfaces for both CGP and Webmin right after the server boots up. But after about 10 minutes or so, I can no longer access either web interface. The server itself still functions normally. I can get on the internet with the server, and I can control Webmin via localhost:10000.
The only thing that allows me to connect to it from my workstation again is to either restart the server, or go into "Network > Linux Firewall" and click "Apply Configuration". What's going on that makes my remote access stop working?
I have openSUSE 11.2 installed and i need to create a gateway server that allows virtual private network connections. I want to play with my friends some lan games, but we are in different networks, so i want to create this gateway server so we can connect with VPN clients to this server and play freely.

I first tried an upgrade from 11.3 to 11.4 and lost Internet Access, so i re-loaded 11.4 from scratch on clean partitions.
I am connected to my wireless WPA2/PSK connection, have an IP, am able to see the network.
I turned off and disabled the SUSE firewall.
I tried setting Firefox proxy settings to auto and to none, i dont use proxy.
I am currently posting this through an SSH connection to my 11.1 server from the new install of 11.4 on a Dell latitude D600 laptop (not using the on-board Broadcomm that is an issue for a later date).
I am running out of ideas anyone got a clue.
I had a google of this but can't find anything useful. I use networkmanager to configure my wireless card. Currently this only works when I'm logged in to KDE. If I log out the system loses the network connection. Is there a way to make it persistent using NetworkManager?
View 9 Replies View RelatedI just finished a fresh install of 11.3 on an HP 7900 small form factor and have no network connectivity. In Network Tools eth0 shows the state as inactive. Network Connections didn't have a connection, so after letting it create one there is no MAC address. I copied and pasted the MAC address from Network Connections eth0, set up a static address with default gateway, netmask, etc. all set appropriately and rebooted. Still no joy.
I want this to get an address via DHCP, I just set up a static address for testing.11.2 sensed the NIC without issue, but 11.3 doesn't seem to like me right now.I wanted to get this deployed on 40 machines today. Oh well.
network manager isnt showing any network interfaces. ifconfig shows wlan0 and eth0 and internet is working. how can i get network manager to manage those connections?
View 8 Replies View RelatedI remember when using openSUSE 11.3 with KDE 4.5, the network connections started to show the last date used for my "NIC".I am using the plasmoid-networkmanagement plasmoid and KNemo.After I downloaded and installed openSUSE 11.4 64-bit, the network connection no longer shows the last date used. I have set up my card via Yast and Iam connected directly to the Internet. No proxy.To find where this is located, navigate to:Configure Desktop --> Network Settings --> Network Connections --> Wired tab.
View 2 Replies View RelatedFirst a warning that I'm so clueless it hurts. Initially I entered the Linux world as a solution to my blue screening Alienware Aurora desktop (which later fried anyway ironically enough). I decided to give up on Windows for everyday use cause you can't strangle an operating system. My first and there after Linux experiences have been fantastic. Internet works without prompting through various distributions of Ubuntu, Mint, and KDE with the exception of enlightenment.
But now I come to openSUSE 11.4 and as my title suggests I'm having a hard time connecting to the internet. I've got a wireless card and router and all that jazz but I can't even select the options for wired or wireless connections under Network Connections in the Network Management Settings. Everything is greyed out except for VPN. I even have the desktop wired to the router and it still is not giving me any indication that it will connect.
I'm wary of trying to enter ip addresses and things of the like because I honestly don't know what i'm doing here.
My router is a Netgear N150 Wireless WNR1000 and in the Kinfocenter under Device Viewer I found my wireless card to be a RaLink RT2561/RT61 802.11 g PCI and my wired device thingy to be an Intel 82540EM Gigabit Ethernet Controller.
I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.

Setup: Notebook with openSUSE 11.2 using KDE 4. Using Network Manager to manage network connection (although I've tried configuring this using ifup as well with no luck).
I need to be able to connect to client networks via a network cable (Ethernet) and connect to the internet via my MiFi 2200 Mobile WiFi. Both cards/connections are active with the following:
I have no problem mounting drives from the client's network. But, can not reach the internet. If I disconnect the ethernet cable, the browser will immediately connect to the internet and load web pages.
I'm assuming the ethernet connection is taking precedence over the wireless connection?
I can't imagine that there is not a way to set this up. If Windows can do it, I'm sure openSUSE can!
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?
My question is simple - is there any linux app or applet which is able to show (monitor) incoming and outgoing connections assuming it's a direct internet access? I was using a firewall on a system off Redmont which was able to show every connection, listening ports of services if some were opened etc.
View 1 Replies View RelatedMy home computer has 11.3 and SuSEfirewall enabled. It connects to the net over the wireless and SuSEfirewall has this connection in the external zone.
I can successfully ssh into this computer from remote (the work computer) but none of the ssh port-forwarded connections work. I'm trying to tunnel VNC over ssh. I also tried setting http on the home computer to serve pages on a high-numbered port (8090) and tunnelling that but it also didn't work - proving that it's not a VNC problem.
Here are the relevant messages from the firewall logs on the home machine:
Code:
I don't understand why this isn't working now, I had the same setup on 11.2 and it worked fine.
The 95.91.92.92 is the public IP address of my home router, I don't understand why a connection would appear to be coming from there when I use ssh-tunnelling?
My ISP has for a long time had a broken forward/reverese DNS so that my ADSL connection with static IP address resolves to a completely different IP address on a reverse query. This has not been a problem until I upgraded a remote server from 10.3 to 11.3 last weekend and now ssh connections from my ADSL connection to it using public/private keys are being rejected with the following message in /var/log/messages (IP addresses changed):
Aug 10 12:00:32 penguin1 sshd[1270]: Address 83.175.246.243 maps to 83-175-246-243.static.dsl.aupex.com, but this does not map back to the address - Possible Break in Attempt!
But if I log in interactively with username & password, the connection succeeds. I've changed the StrictModes setting in sshd_config to 'no' but this hasn't resolved the problem. Obviously something in 11.3 is being stricter about this IP mismatch than it was in 10.2 (and no, the server is not using a firewall). There must be something I can change to make sshd more permissive? I've tried before to get my ISP to fix their problem but no luck. This needs to be sorted as a server at my home (which does not run SuSE) retrieves backups from the remote OpenSuSE 11.3 server every night using scp and these are now failing.
Every single time I enter the network manager to edit connections is crashes on exit. I am running opensuse on an Asus eee PC 1000HE with an Atheros network card. The crash report follows :
Distribution: openSUSE 11.2 (i586)

As an extra point. I wish I could disconnect individual networks instead of just disabling networking to disconnect. I think the newer version of the network manager does this.

View 2 Replies View RelatedI recently setup a new SUSE box for the purposes of acting as an ftp/sftp server. It's currently setup to run ProFTPD 1.3.3.rc3 and mod_sftp/0.9.7. The server has two internal network interfaces eth0 and eth1. eth0 is purely for internal use to accept ftp and ssh. eth1 is outward facing and receives connections from the WAN via SFTP over port 22. The problem I am facing is that after half hour to an hour eth1 stops accepting connections whenever there is no SSH connection present on eth0. I can't figure out why this is happening.
ProFTPD is setup as follows: SocketBindTight directive is on, default server and port are commented out.
[code]...
When the external interface is unreachable the proftpd and proftpd-sftp logs show no record of any connection attempt. I have noticed however if I leave eth0 down eth1 stays contactable without problem. Can anyone give me some pointers on what I can check to find out why this may be happening.

View 8 Replies View RelatedI'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
My OpenVPN config file (some details omitted)
--remote [gateway ip] # vpn12 load:
--remote [gateway ip] # vpn11 load:
--remote [gateway ip] # vpn15 load:
--remote [gateway ip] # vpn16 load:
[code]....
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.
I have my box setup as a router/NAT with two different network cards. One for external connection(connected to the Cable Modem) one for internal connection(used for internal DHCP). It works perfectly when I manually activate the two interfaces after booting(both interfaces always show up as inactive after booting), then the DHCP server and firewall. I am confused, however, by which program has control of these interfaces.
First, there is the Network Configuration (System->Administration->Network), which is where I manually start the interfaces after rebooting. Both interfaces are set to "Activate when computer starts" in here.
Second, Network Device control(System->Administration->Network Device Control), which looks to be almost the same thing as the above.
Third, the NetworkManager applet(on the top bar) - both devices show up as unmanaged when I left click on this, but if I set "Controlled by Network Manager" in the "Network configuration" window(number one above), It still does not work. Can I get rid of two of these programs, or is there some way to edit the startup scripts to start my ethernet cards before the dhcp server/firewall(which is shorewall BTW)?
