OpenSUSE Install :: Configure To The Server And Gateway - Internet Stops Working
Feb 6, 2010
i did install opensuse and everything ok; i did configure it to be the server and gateway for a little office network Everything seems to be ok most of the time but sometimes (usually between 5 and 7 pm each day) internet stops working and there is no way to let it start again. So i turn off the suse, switch all cables to the old fedora server, just turn it on fedora and internet works. Turn off fedora, connect suse, let it start and everythng ok...it happens all the times

Last night I upgraded the kernel to 2.6.34.4-0.1-desktop and now X has stopped working. I can go into run level 3 OK.
I have tried removing the xorg.conf file, using a copy of the install xorg.conf. I have also tried reinstalling the ati drivers
-rwxr-xr-x 1 readyp home 101178081 2010-08-07 23:45 ati-driver-installer-10-7-x86.x86_64.run
-rwxr-xr-x 1 readyp home 103164399 2010-08-29 21:25 ati-driver-installer-10-8-x86.x86_64.run
the ATI drivers stop at 75% and do not complete.
If I go into run level 3 and run startx the screen goes black and all the keys stop working (Ctrl-Alt-F1 etc..)
I can attach the Xorg.0.log if you like, but it does not look strange.
I am sure the hardware is OK as I have my system dual boot with 11.2 and 11.3.

I need to place an Ubuntu machine on a network where I have a DHCP server which does not configure the Degault Gateway parameter (we don't want ordinary users to browse the internet). Is it possible to leave the machine using DHCP and define the Default Gateway manually (as in Windows XP i.e.)? How?

I just recently erased my hard drive and installed ubuntu 9.10 all over again. I updated as expected and everything was going well, until, my internet stopped working after maybe 40 mins or so after a successful boot. Now this same thing happens every 40 mins and I have to reboot the computer by forcing my laptop to shut down by holding down the power button. This also made me aware of another problem when restarting or logging off my laptop. The laptop hangs at that terminal-syled screen and the underscore blinks and fails to shut the computer down/log off. I resort to holding down the power button to restart. I am using a wireless connection with WEP key protection.

It just happened again..... I am typing now in tomboy notes....
Time to restart again......
I also try to open terminal and it fails to function (after the internet stop working), any reason for that? I would also like to note that the signal strength decreases as time passes by.......

I just set up a linux server which is acting as an internet gateway. For specific reasons, clients first make a vpn connection trough the internet to the linux server.
CLIENT ---->Internet----->Linux VPN Server ------> Internet
On the linux server iptables is configured for NAT. The problem is that the internet speed becomes slower than expected. I used windows and RAAS and the speed was pretty good. The server has only 1 NIC(eth0) and an alias interface is added to eth0. The alias is eth:0 with ip address 192.168.0.253
iptables config is as follows:
iptables -P INPUT ACCEPT
iptables -F INPUT
iptables -P OUTPUT ACCEPT
iptables -F OUTPUT
iptables -P FORWARD DROP
iptables -F FORWARD
iptables -t nat -F
iptables -A FORWARD -d 192.168.0.0/24 -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A FORWARD -s 192.168.0.0/24 -j ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j SNAT --to MY_VALID_IP

This holds true in Transmission and NOT in Vuze. UPnP is enabled, ports are randomized and open each time. Pings to outside still work fine, but I cannot browse to websites (404 errors) when the app is running. I'm stumped, is Transmission locking all other in bound traffic/ports except the one it wants to use?

Not sure if I've listed the specs of this machine before, so I'll do it again. 'm running an HP Pavilion 760n with 512MB of RAM and (I think?) a Pentium III processor... not sure on that one right now. It's currently running a laptop version of Ubuntu 10.04.I went to log into my online classes tonight only to find that the computer wasn't responding at all. I did a hot shutdown and restarted it, and now the system isn't detecting the internet connection at all. It should be noted that the connection was working perfectly fine earlier today, perhaps 6 or 7 hours ago.I know it's something to do with my computer and not my router, as I'm on my wireless network from a Windows 7 laptop and it's connecting just fine.
In viewing another thread,..lems+-wireless, I found a bunch of commands that it was said would be helpful diagnosing this issue. That said, below is the output of all the commands that I could think of.
Sudo ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:e0:18:5c:45:7a
inet addr:192.168.2.1 Bcast:192.168.2.255 Mask:255.255.255.0

Im having problems with Ubuntu 10.04. My wireless disconnects frequently and firefox seems to stop working. it seems the connection times out sometimes when firefox stops. other times the connection just disconnects. When I was running 9.04 everything worked and nothing disconnected, so I know its not my computer.
My laptop is an IBM t40, 1.4 ghz, 2gig of ram.It does not seem to mater if Im using the wireless or the wired connection. The problem happens either way.does anyone have a solution for this?

I haven't worked with linux before, I am a network administrator, mostly working with cisco routers and windows 2003 server configured with ISA, I want to shift to linux, since its a free OS, offers more than windows 2003 server, and I have the time and resources to test it at my work place, I want to give it a try. Now ... this is what I want:
I want to use Linux OS (server or desktop editions) as Internet Gateway, I have less than 50 hosts (internet users) on my network, and I simply want to know what is the most convenient linuxs distro for me to work with as a beginner to install, configure and administrating a linux OS(working as an Internet Gateway).
Its a simple network, 50 users connected to a switch, the switch to a server (where I will run the linux OS), the server to a cisco router, the router to the internet line. (Any tips on what do I need to be able to configure firewall rules and user activity monitoring like I am used to do with ISA on windows server 2003).

Since I have a new internetaccount, 2 days ago, I have a problem on my server [Fedora Core 8]. I use it as a router.
eth0 is for the internet.
eth1 is for my LAN.
But since my new internetaccount my server uses eth1 for the internet. This is a line from my syslog:
Code:
NetworkManager: <info> Policy set 'System eth1' (eth1) as default for routing and DNS. I killed the NetworkManager daemon and now it works but this must not be the way to do it? Where do I tell my server that I use eth0 for routing and DNS?

What I need is some information to be studied and learned by me in order to be able to create with Ubuntu Server an Internet Gateway Server. From my ISP I get about 50 public routable IPs through DHCP. Into my LAN I need to forward this public routable IPs to machines but I want to be able to manage bandwidth and also to be able to enable or disable Internet access for every client machine. Maybe with subnets? Maybe with dchp really? It would be nice if it would possible through DHCP!

I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.
3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?

I have a wireless cable modem/router and a PCI-E 1x wireless card in my desktop PC. It works perfectly until I connect my Ethernet cable to my local router and printer, no more internet connection. I am guessing there is a setting somewhere that tells the networking software that the hard wire connection is the primary internet gateway. How do I tell it to use the wireless as the primary gateway?

My organization has been using PASV FTP via VSFTPD for some time now. We have defined the port range between 30000 and 33333 and as I mentioned, it has worked up to 20100108 (last Friday). It appears that VSFTPD is not negotiating the defined PASV port range, which we can see with both netstat and tcpdump. Has anyone here run into this before? Are there any VSFTPD hackers out there who know what mechanism VSFTPD is using to re-allocate the ports? I would think that it would release the port, and flag it as unused, or something.

On my virtual server I had the same issue within the last three month. The postfix daemon stopped working suddenly and I don't know why. I can restart postfix normally and it's working normally for a couple of weeks until the next crash. Does anyone have the same problems with CentOS 5.6 and postfix?

my netbook (running 10.10) has recently decided to only work with my wireless for a short while after connecting. After this time, it just won't load a page at all, but remains connected to the router. Disconnecting then reconnecting to the network allows me to use the internet again, but only for a short while. This is a recent problem, and the netbook used to "just work" with wireless.

This is an intermittent problem. My mouse works on boot, but stops working periodically. Once it stops, I have to reboot the computer. The problem is more than a little annoying. My hardware and software is as follows:
*AMD Phenom X3
*Integrated geForce 8200 GS
*Opensuse 11.3 64-bit
*Mouse - microsoft wireless comfort mouse 2.0
*Keyboard - microsoft wireless comfort keyboard 1.0A
I am not sure what logs I should attach. The contents of /var/log/messages leading up to the mouse stopping is as follows:
Code:
Aug 11 21:10:39 linux-r1v4 kernel: d:Ukonkyrlae tasae e ,cd x1o s06/ei0.<> 42159]akdsro:Ue'ekyoe 01<ecd> omk tkon

BAM your ftp doesn't work. Out of the blue my ftp connections stall when I ask for a directory listing. I am using ncftp as I have for several years. And after a long pause I get the answer:Data connection timed out.Falling back to PORT instead of PASV mode.I then get the listing and the connection continues in PORT mode. But not with FileZilla it just hangs. Also bit torrent no longer works. Set up is a home network of 6 machines reaching the internet through a linux firewall box, qwest DSL modem gt-701-gw. Nothing has changed but sometime in the last week something has changed because now FTP PASV and BIT TORRENT can no longer connect.
I am holding back from completely rewritting the iptables/shorewall rules and have spent the day with the website host 1 and 1 and Qwest. Trying to find a solution. This problem is universal, all machines (windoze and linux) and all software (coffeecup, ncftp, ftp, filezilla, bit torrent).

My mouse stops working under vmware I have ESXi 4.0. Reboot or (Ctrl) (Alt) (Backspace) fixes the issue. I'm seeing the same thing in OpenSuSE 11.3 running on ESX 3.5. Using the open-vmware-tools as part of the OpenSuSE install. Odd thing is that I have (3) 11.3 machines, 1 has never shown this behavior, I seems to have gotten another to stop by changing the KDE Activity setting Type to "Plain Desktop", and 1 that for the life of me I can't get it to stop.
The first one has been upgraded from 11.1 -> 11.2 -> 11.3. The second was 11.2 -> 11.3, and the third is a fresh install of 11.3. I'm able to fix it for a limited time by logging out or restarting X with Cntrl+Alt+Backspace. I've tried restarting the vmware tools without luck. I'm wondering if it is an Xorg bug.

I have an issue on a few servers where IPv6 stops working after a reboot. I can ping anything within the same subnet but anything outside of that it gives me host unreachable. I believe that it is not routing for some reason, but I am not sure why. I have tried adding a default Ipv6 route for Eth3 but nothing seems to work.

I have one server at home, connected through a router that gives me a static IP:192.168.1.2 - My PC192.168.1.3 - CentOS serverI enabled the port 80 into router forwarding system and I can connect properly to CentOS server, using the IP my internet provider gives me. My router automatically forwards a changed IP to my dyndns.com account so I can also access the server through a domain name (I pay to have it linked to one of my domains).My next step is to configure the mail server (dovecot) , so I can send emails from my local server(192.168.1.3).I was wondering if anyone has any tutorial links or tips to have the mail server configured through a home internet provider + home router.
