Ubuntu Networking :: Apache Binds To Ipv6 But Not To Ipv4?
Sep 1, 2011On my 10.04 LTS Ubuntu Server installation, apache2 doesn't bind to ipv4. It does bind to ipv6. I didn't notice this at first, because from my home connection I could visit the webpages without trouble. I noticed it running netstats -ta:
Code:
tcp 0 0 localhost:10024 *:* LISTEN

Networking :: Ipv6 Stack Not Enabled On Centos 5.6
Jul 25, 2011I've got a little server setup on my local network and I'm trying to configure it to use miredo. I've got my laptop successfully using it, but for some reason miredo gives this error when I try to start it:
Code:
Error: IPv6 stack not available.
also running "lsmod | grep ipv6" gives these results
Code:
ipv6 270049 1 cnic
xfrm_nalgo 13381 1 ipv6
I get the impression that ipv6 is not enabled on my server, but I'm not sure how I enable it short of doing a reinstall.

Ubuntu :: Processes Listening To Ports / Ipv4 | Ipv6 Only
Jul 3, 2011I'm running a native dual-stack (ipv4 & ipv6) dsl connection.So, I've been adding firewall rules, cleaning up unwanted processes, etc to tighten security.I'm left with only 3 processes that are listening to ports. mysql, ipp & ssh.Still not quite sure I need mysql. I run Amarok but without using a database, so I don't actually use sql for anything that I'm aware of.Anyway, my question is;Is it possible to make any any of these processes listen to ipv4 only or ipv6 only? Is there a distinction there at all?
Example- ssh is currently listening to port 22 on both tcp & tcp6. I do all my ssh connections using 'ssh -6', so, Can I make ssh listen to tcp6 only, or ignore tcp ?

Ubuntu Security :: Set A Rule In Iptables, Does That Rule Also Apply To Ipv6, Or Just Ipv4?
Jul 16, 2010Question (and Google results aren't making this clear): Ubuntu has both iptables & ip6tables installed. 1. If I set a rule in iptables, does that rule also apply to ipv6, or just ipv4?
2. If "no" to above, then it would be prudent to *also* set ip6tables rules as well if I want to maintain an active firewall, correct?
3. Does ip6tables rules have the same syntax and behavior (more or less) to iptables rules - i.e. can I just copy my iptables rules & change "iptables" to "ip6tables"?
4. Any gotchas or issues that I should be aware of?

View 2 Replies View RelatedFedora Networking :: FC15 IPV6 Wireless Router - No Longer Gets An IPv6 Address
Aug 31, 2011I have been struggling to get FC15 to act as an IPv6 router for a while now, am sure I am missing something trivial.. The idea is that I have a ppp / adsl connection (this works fine), use the wireless card on my pc with hostapd and dhcpd to provide connections to other pcs (works fine), and radvd to delegate ipv6 addresses.
The issue seem to be that as soon as I turn on ipv6 forwarding (net.ipv6.conf.all.forwarding =1), the ppp connection no longer gets an IPv6 address. This means the router cannot ping any ipv6 address outside my network.
If I disable ipv6 routing, my router gets an IPv6 address on its ppp connection, and can ping things such as ipv6.google.com just fine, however (of course) no packets are forwarded from my network and radvd complains that forwarding is disabled.

Slackware :: Disable And Enable Ipv6 Connectivity?
May 7, 2011I just finished setting up my slack machine as a home server (printers & files) and I noticed that I have an IPv6 address (from ifconfig)... I didn't know I did. I used to work in tech support and when a windows or OSx machine didn't connect properly on a LAN, disabling IPV6 was a common troubleshooting step. Is there a way to easily turn inet6 connectivity off/on in Slackware? (I want to keep the ability to get an IPv6, we will all use those in the future)

View 2 Replies View RelatedUbuntu Networking :: 7.10 - No IPv4 With Eth0 - Can't Connect To LAN
Apr 19, 2010Current problem: fresh, clean install of Ubuntu 7.10 on known good hardware does not use/produce/get/have an IPv4 associated with eth0, so cannot connect to my home network for Internet access.
Background: Have been wanting to build and maintain a home file server for some time now. Have also been wanting some hands-on practice to help me progress from Noob to Intermediate, eventually advanced Linux Tech. (I have two decades of tech support experience, but only small fraction of that using command lines and almost zero Linux.)
Anyway, every time I download and attempt to burn a recent distro on my Vista Shuttle, I only end up making drink coasters and mini-frisbees. so I thought that I might have better luck if I used a Linux Workstation to download and burn a server distro.
That's where I an now. I took one of my fully functional WinXP systems offline, replaced the WXP HDD with an old 3.2 GB, dug out my 2008 edition Linux Bible, popped in the DVD that came with it, and installed Ubuntu 7.10.
Everything else seems to have progressed smoothly, but I cannot seem to get the onboard Via chipset ethernet controller to talk to the router. When I run "ifconfig" in Terminal, I see IPv6 info, but nothing for IPv4.
When I try to configure eth0, it doesn't matter whether I set it up for DHCP or static... nothing works.
Is there a command line tht I can use in Terminal to manually configure eth0 to use IPv4?
Ubuntu Networking :: Configuring IPv4 With Fixed Ip?
Aug 2, 2010Our router is pretty old and only capable of giving fixed ip and there is no support for IPv6. Via the gnome networkmanager I try to set a manual IP to 192.168.1.123 and a netmask to 255.255.255.0 and a default gw at 192.168.1.1 . However, this does not work.
If I open a terminal and type:
Code:
sudo ifconfig eth0 inet 192.168.1.123
sudo route add default gw 192.168.1.1
Then I get a perfectly valid connection to the internet.
ifconfig by it self returns:

ffor me it seems that the gnome network manager doesn't save the information that I gently ask it to.
I can fix it with the CLI commands, but I would like to know whats going on.
Networking :: Duplicate Address Detection In Ipv4?

View 2 Replies View RelatedNetworking :: No IPv4 On Eth0 - No Connect To Router
Apr 20, 2010I have tried clean installs of Knoppix v0.6, Xandros 2.0, and Ubuntu 7.1... same issue with all. I cannot seem to get eth0 (via chip on mobo) to get/have/use IPv4. ifconfig shows only IPv6. (I cannot paste any info because linux desktop is on different box.)
End result is that I cannot get the linux desktop to connect to my lan, either with dhcp or with static ip.
I have a belkin router configured as my gateway 192.168.3.1 and nothing fancy with the setup. I have dhcp open for 192.168.3.245 thru ...254 and at most there are only 4 systems in home connecting with dhcp at any time. all other systems have static addresses.
I have two decades of desktop and lan support under my belt, but relatively small amount of command line experience and almost no history with linux (unless you count a dozen unsuccessful attempts to burn linux distro install discs on this Vista desktop).
Therein lies the start of my prob. I need to build and manage a fileserver for my home, but cannot seem to get a working installer cd or dvd to burn from anything I download.
So I said to myself, "Self," I said, "you're a tech. Build a workstaion, use the DVD that came with your Linux Bible (2008 Ed.) to install one of the linux distros on it, then download a recent, stable server distro and burn it using the linux workstation."
Unfortunately, if I cant get an ipv4 connection to my home network, I cant get out to the Internet to download any newer ISO files.
So what am I missing or doing wrong? How do I tell linux to stop trying to use IPv6 and let me use IPv4?
BTW, eth0 works just fine if I install Windows on that PC, so I know its not bad HW. Could it be a driver issue? Or do I need to use some Terminal command to turn off IPv6 and reconfigure eth0 for IPv4?

Networking :: CentOS 5 System With Squid 2.6 - How To Enable Delay Pools
Apr 2, 2011I have install squid 2.6 in my cent os 5 system. The proxy server is working perfect using the following method.
Code:
[root@localhost squid-2.6.STATBLE22]# ./configure@--prefix=/usr/local/squid
I want to enable delay pools feature in it.For that purpose I do as following
Code:
[root@localhost squid-2.6.STATBLE22]# ./configure --enable-delay-pools && "configuration successful"
The question is should I configure it as I do it for squid
./configure --enable-delay-pools--prefix=/usr/local/squid
To enable delay pools may I need the correction in the steps which I have taken.
[root@localhost squid-2.6.STATBLE22]#make
[root@localhost squid-2.6.STATBLE22]# make install
In short to enable delay pools may I just use
# ./configure --enable-delay-pools
then
#make
#make install
