Fedora Networking :: F15 Gnome Install - No External Connections
Aug 2, 2011
I am new to Linux but not UNIX, I have been an HPUX SA in a previous life and now Oracle DBA. So I installed F15 (Gnome) onto an intel machine using LIVE USB from website. Install has gone fine but I have no external network access. I have tried for a couple of days to get this working but no luck. I can ping internally on our LAN but no external connections. I cannot ping external web sites from my PC either so guess work have locked it down in the firewall but I can browse from my PC so was hoping to be able to use Firefox and YUm etc from my F15 install. Which sort of leads onto my second issue which is setting up a remote X client session, I was trying to install VNC with YUm when I found this issue.
Here is some info:
[root@hrdevdba1 etc]# cat resolv.conf
# Generated by NetworkManager
domain hayshps.com
search hayshps.com
nameserver 10.190.27.14
nameserver 10.190.13.1
nameserver 10.190.13.13
# NOTE: the libc resolver may not support more than 3 nameservers.
# The nameservers listed below may not be recognized.
nameserver 10.171.90.215
nameserver 10.175.151.236
[root@hrdevdba1 etc]# ifconfig .....
I should add that I have also attempted to disable IPv6.

I just upgraded to 15 and was wondering if it was possible to specify which devices to prioritize a route through. I have my machine, a laptop, connected to my family's router for an internet connection and a wired connection to a personal router for a faster and private connection between my other two computers and a network storage device. Whenever the laptop is connected to my personal router everything goes through it and it can't connect to any external web sites. But when I unplug it and go only on my family's wireless everything is fine, except I can't connect to the storage device since it has no external connections.

I've got the following two subnets.
Code:
Subnet 1: 10.1.0.0/24
Subnet 2: 172.16.0.0/24
A machine in subnet 1 is natted to a static address in subnet 2. For instance 10.1.0.10 is natted to 172.16.0.10.
I have achieved this with the following iptables rule. (in addition to enabling forwarding)
Code:
iptables -t nat -A POSTROUTING -s 10.1.0.10 -j SNAT --to 172.16.0.10
So far this works perfectly. What I want to do now is to add another rule that only nats the machine in case it is NOT accessing subnet 1.
In other words, when this machine accesses any other machine in subnet 1, it should show up as 10.1.0.10. Whenever it accesses subnet 2 of anything else, it should appear as 172.16.0.10.

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.

I Installed Ubuntu which was on the laptop before and this install doesn't want to work with a Internet connection. I know my connections is good and the Laptop is fine because it used to have dual boot and windows connected fine.

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)?

I have exim setup on squeeze to run as an "internet site". Outgoing mail works fine but it seems to just ignore incoming smtp requests on port 25. I can see the incoming connection via tcpdump but exim doesn't seem to talk. If I connect via telnet it rather quickly says connection refused. Is there something additional I need in the Exim conf?

I just installed Fedora 14 in a hard disk of my PC. I installed MySQL also. I dontt know if this is the correct site for my question, but nobody MySQL related, have an answer yet. For MySQL accepting remote connections, my.cnf file must be edited (bind-address line or skip-networking line in that file). Well, that file in my Fedora-MySQL installation does not have such lines, so i assume, TCP/IP connections are allowed in MySQL. When i try to connect to the MySQL server it refuses the connection with the error 2003, that in short, means no TCP/IP connections are allowed. I disabled the firewall and retried but with no success, enabled the firewall again, and nothing happen. Is Fedora not accepting TCP/IP connections?

once I updated , there will be no connections to Internet in GUI , while it's available in TUI . So it's wired , huh ? Before upating, it's available both in TUI and GUI, though all the time the network-manager shows no connection , in fact , there is and both GUI and CUI . Now I updated , and it can't access Internet from GUI.

Latest kernel update since Fedora 2.6.33 are mapping all my NFS "shares" twice (two sets of icons, etc.). All work, but why is this happening - was fine previously.

ok so the router works in windows and i know the config details of it.i can see other wifi access points in the area but not my one. i have tried joining it as a "hidden network" to no avail.is there any reason why fedora would not detect my own wifi when it detects substantially weaker signals instead??

I have a question, regarding the use of two internet connection on the same server. So, the thing is like this: The server will have 3 network adapters: connected to a DSL modem (on this adapter I have one of the internet connections, a PPPoE connection. It's only purpose is to share the internet connection to all LAN users using SNAT.
eth1 ----> the other internet connection, a much more expensive one actually, used for hosting a website, a domain name server, and a qmail server. eth2 ----> LAN connection So what I want is to make eth1 the "default gateway" (for outgoing mail, DNS requests, etc) and, as I said, use the ppp0 connection on eth0 only for internet sharing in LAN.
My question is (since I'l configure this server in about one week), does anybody have any suggestions regarding how could I accomplish this? I mean, I'm affraid that ppp0 will also try to use the default gateway from the other internet connection and vice-versa. Now, I know I can use the ip route/ip rule commands, but for many reasons I'd like to keep it simple and not use them.

On a Fedora 11 machine, I configured ppp0 on eth0 and ppp1 on eth1, each one is connected to a modem, I also defined ppp0 as the default gateway.. Should I do anything else to load balance the 2 connections or will ppp1 take some of the load by default? Should I add any other routing rules? If yes then please tell me what should I add, keeping in mind that for each pppoe connection both the pppoe address and the remote address are not static so I actually needed some scripting to change the default gateway each time the remote pppoe address changes.

I have two internet connections. One is wired ADSL Broadband & another is USB EVDO modem. I can use only one source at a time. That means the traffic will pass through either ADSL or EVDO. Other connection just sits idle. I want to use both the connections together so that I will have increased bandwidth. Is there a way to do that?
My computer has one NIC card. Both ADSL & EVDO use dynamic IPs.

Just moved over from the dark side (Vista) and was wondering how I can get two (or more) PPTP VPNs connected at any given time. I usually attempt to multi task (although swambo says I can't) and work on various clients' servers at the same time. The GUI network manager thingy only allows me to dial up one VPN at a time. Is there perhaps a cli version and if so where would I go to get a tutorial on this please. BTW, running F11 32bit. Tried Debian and Ubuntu as well and found F11 to blindingly fast on my DualCore Toshiba laptop. Pity I can't see the additional 1Gb of RAM though. (4Gb in total).

Code:
[bee@localhost ~]$ ulimit -a | grep files
open files (-n) 1024
that open files value set to 1024, but is it valid only for real files ("file handles/descriptors" of files on your filesystems: hd partitions / cdrom / floppy / usb devices) or does it counts also network/sockets connections? i'm just asking without a reason. it's just curiosity ... as you can see sockets with lsof, somebody like me could think connections are counted as they were "files" by ulimit too

I got 2 ADSL accounts from a provider, so I decided to configure a server as a gateway for my other PCs.. I created ppp0 device using pppoe-setup over eth0. Then I configured the second one as ppp1 over eth2 to the second modem.. When I finished, I used ifconfig to check the settings and I got only ppp0 and didn't see ppp1, I tried to ifup ppp1 but I still get one device with ifconfig.. The adsl-start command starts only ppp0.What should I do to get the 2 lines to work simultaneously?Are there any configuration files that need to be edited?

My current network setup at home is all wired, and that's worked for me so far. Now I want to set up a wireless connection on my Linux box that I can connect to with both my laptop and my Nintendo DS. I'd like to be able to host a wireless network from the Linux box, connect to it with some other wireless device, and have the wireless device communicate with the router, the internet, and other computers on the wired network. I have the wired network set up (statically configured) as eth0. Other network adapters present on the system are eth1 (not in use) and wlan0, wlan1, and wlan2 (identical cards, remnants from the last time I experimented with wireless).
So I guess my question comes in two parts:
1) How do I set up wlan0 such that it can host? Is Ad-hoc mode okay for this, or do I need to set it up in Master mode?
2) How do I forward connections between the wireless net and the router?
Note that I will be using WEP, as it is all that the NDS supports. I'd like to set up MAC filtering as well, but not until after I get something that works.

I want to write a custom rule to allow all connections to the ip addresses on my local network (192.168.2.2 through ...99) but I don't know how. I know adding a custom rule asks me to read a file and put it in "iptables" format, but I don't know how...

I'm having a problem that seems to plague a lot of people judging from my research on the web. I have a hosting provider that limits the number of incoming connections to the shared host to 50 per IP.
I have a single IP for outbound connections and I use Squid as a proxy server.
Lately I've tripped across the 50 connection limit frequently - and that's with only 1 user. It seems the problem is related to the performance you can get out of a desktop these days. Its not impossible to have several browsers open with several connections to different sites on the same server - and boom - locked out!
So it occurred to me that there must be some way to limit the number of outbound connections in the kernel - but I've not found it. I did find that Microsoft had been limiting the number of outbound connections in XP to 10 to address the virus problem, and I've found countless hosting complaints and dialog on the subject with no easy solution.
So my question is simply, does anyone know how to limit the number of OUTBOUND connections to a single IP in the kernel?

I have a machine that I'm trying to setup as a reverse web proxy. It will have two NICs, eth0 will face the public network, and eth1 will face the "internal" network (connects to a switch that goes out to the other web servers that are statically assigned a private IP address).
When both interfaces are started, I can ping hosts on the 1.2.3.0 network and the 192.168.10.0 network without problem when doing so by IP, but if I try to run a ping or nslookup command with a DNS name, it does not work. I've tried commenting out my entries in /etc/resolv.conf and adding the DNS entries in the /etc/sysconfig/network-scripts/ifcfg-ethX files directly (DNS1=x.x.x.x and DNS2=x.x.x.x), but the results are the same.

I need a utility to record the traffic on a particular TCP port. I know there are packet sniffers that can do this, but I don't need to monitors the wire, just the traffic to and from my own computer. I would assume there is something out there that can hook into the TCP stack and copy the data to a file just before/after it goes out/in, but my google fu has failed me.

I installed Nvidia drivers according to the post in HowTos section. It downloaded a different version of the existing kernel, i guess. And the kernel using which I downloaded, when shows up GUI, looks like a Safe Mode of Windows. So I boot the kernel that it downloaded. And there the problem is that in Network Manager applet, it doesn't show me the wireless connections. It doesn't even show the Enable Wireless checkbox upon right clicking it. How to get it back?

I am using a VPN proxy service for privacy reasons. I have configured NetworkManager and it's PTPP VPN plug-in successfully.
I would like to configure NetworkManager to drop connections when the VPN fails so that I do not suffer 'privacy leaks' when it happens.

I have a problem with my F13 and wired connections on my Acer TravelMate 2410. When I connect the inet cable it doesn't show it as connected. When I type ifconfig, it shows everything as it should. When I tried to bring up eth0 with ifup eth0, it said that the device is not managed by NetworkManager. I tried to restart nm with service network restart, but it gave this error:
Shutting down loopback interface: Error org.freedesktop.NetworkManagerSettings.InvalidConn ection: ifcfg file ;/etc/sysconfig/network-scripts/ifcfg-lo' unknown
The same error came up for eth0 and Wired_connection_1 (the connection I configured from NM )
When I typed nmcli dev list it gave me:

I'm trying to get wireless working in F10. Using pci wireless card with Atheros chipset. To be sure, I tested this hardware with a PCLinuxOS Live CD. Connects to AP perfectly.
Hardware drivers seem all OK in F10, and ifconfig shows wlan0 as expected. When I use the Wireless-Assistant 0.5.7 there's no connection.
Actually, the AP logs show numerous connections and disconnections.
Preferring CLI, I'm using a drop-dead simple wpa_supplicant.conf as follows :
