OpenSUSE Network :: IPv4 Entry For Localhost Missing In 11.4?
Jun 28, 2011
I had some fun here, with my local Cyrus IMAP daemon. I "updated" the machine to openSuse11.4 (from 11.2) by doing a fresh install. Because some of my involved HW here isn't capable of IPv6, I switched it off using yast2:
Netzwerkgeräte/Netzwerkeinstellungen [my translation: Network devices / Network Settings] Globale Optionen [global options] Removed the mark on "IPv6 aktivieren" [activate IPv6]
Then I had a hard fight with Cyrus IMAPd, mostly caused by user brain damage on my part... But one thing really looks like a problem on the Suse side of the fence: My /etc/hosts missed the "localhost"-entry for IPv4 ! This was the contents:
Code:
# special IPv6 addresses
::1 localhost ipv6-localhost ipv6-loopback
127.0.0.2 godot.site godot
[Code].....
I haven't seen this effect on 11.2 here and I haven't seen it on "my other" machine (running 64 bit version of Suse 11.4). But there I think IPv6 is still activated. I will check this, as soon as I get there.
Should this be reported as a potential bug in 11.4 ? Or is there some way, I could have messed up this. (No I didn't edit /etc/hosts by hand, before I corrected this thing)

Is there a way to access today the openSUSE servers via IPv4? My ISP does not support ipv6, nor my router, and I can't install software right now in openSUSE, because it wants to access te servers via IPv6.
If would be grat to have the download.opensuse.org ipv4 address.
I really need to install some packages, they are required for my school project.

How do I assign IPv4 and IPv6 static addresses permanently in OpenSUSE 11.2? Currently I am only able to assign either IPv4 or IPv6 static address not both. I cannot find even the interfaces file(/etc/sysconfig/network/interfaces).

We're trying to replicate something that Windows servers can do. Basically on a Windows box, you can give it a static IP address, but there is an option to have it update the DNS server with it's IP and hostname. We are trying to do this on SUSE 11.I know I can get this function to work on SUSE if the box is set up as with DHCP. What we're having difficulty is when the server is set up as a Static IP to get it to update the DNS server

I have a problem with one of my new OpenSuse installation. I install ntop on this machine so the port 3000 become open, but when i want to use it on a other pc, it cannot see the open port. I really don't understand why i cannot access this port.
I disabled firewall to make sure everything pass.
Here my ntop on my localhost
Nmap done: 1 IP address (1 host up) scanned in 0.07 seconds
Here my ntop from another host
Nmap done: 1 IP address (1 host up) scanned in 0.07 seconds

This is a follow-on to "samba write failure crashes linux". It has the dmesg output when the write failure occurs.The remote server is os/2 v4.50 fp3.The failure occurred in this instance attempting to write a file from the localhost to a samba-mounted resource on a remote host. The failure always happens when at least 3 MB have been transferred. Smaller files are not a problem.
Other cases:
1. Saving any email (thunderbird) attachments to the localhost,
2. Downloading anything to the localhost using Firefox.
The most notable aspect are the phrases "kernel BUG" and "invalid opcode".

I got everything working except any localhost connections from within the server. I've tried to connect using localhost, 127.0.0.1, and dedicated IP from within the server and several CMS sites I have moved over to the server and all the local host connections fail.

I recently installed OpenSUSE 11.3 amd64 from DVD on a new HP 625 Laptop. Whenever networking is activated, application startup slows down significantly. When I deactivate networking in the nm-applet application startup is fine. I am using the broadcom-wl package from packman for the broadcom wireless card (BCM4313)

I installed WordPress 3.x on my localhost/Apache server, but I can neither install plugins nor update anything.This happens with both the stable WP3.0 version and the 3.1 beta. When I try to search the Plugin Directory from the WP dashboard, I get this message: An Unexpected HTTP Error occurred during the API request.When I run an update, I get a page asking for the login credentials for the ftp user ("To perform the requested action, WordPress needs to access your web server. Please enter your FTP credentials to proceed. If you do not remember your credentials, you should contact your web host."). Since I'm part of the 'ftp' group on the system, I enter my system login information, click Proceed -- and get a blank page that does nothing.
I've gone to YaST, and I see that the system ftp user has a 6-character password (which may or may not be mine). I'm afraid to change it and risk screwing up other ftp-related functions. I'm running openSUSE 11.3, and am obsessive about updating. I will note that I have an old 2WIRE router that often requires me (including Zypper repos) to enter IP addresses instead of DNS-based URLs to successfully download stuff. Not sure if this is related, but just in case...

Can someone explain me ipv4 notation like:
192.168.1.0/255.255.255.0
Does it mean "any host on 192.168.1.x" network?

Can I just copy all the files in /var/lib/mysql >>reinstall MySQL >> copy all the old folders into the new /var/lib/mysql ( while MySql is off)

I'm working in windows, and that's why I have been able to access the network. In F14, I was able to access the router address while the internet access ain't. Tried restarting network, and still the problem persists. Tried [URL] and the only thing that i've infered is that IPv4 Failed: FATAL plus, the routing table showed 0.0.0.0 as one of the entries (Gateway). So, i've deleted the wired network configuration from the Network Configuration and checked whether the os would pick it up automatically. It still didn't work.

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.

After upgrading from 9.10 to 10.04, a hundred or so of (for example)
Code:
error (network unreachable) resolving '14.42.117.203.in-addr.arpa/PTR/IN': 2001:500:13::c7d4:35#53: 1 Time(s)
messages appear in syslog each day. Each URL has from 2 - 6 attempts at various ipv6 addresses. My question is why is bind9 trying to resolve ipv6 addresses? I have done nothing to enable or disable ipv6 and thought that if not explicitly enabled I would not have to be concerned with it.

For some reason my gconf-editor does not have a ftp entry. (/desktop/gnome/url-handlers/ftp)This is annoying as it sets all unknown urls to firefox. I always liked Nautilus as the default.
I tried creating a %gconf.xml file to $HOME/.gconf/desktop/gnome/url-handlers/ftp/ and still no luck.

Last weekend I upgraded my Opensuse 11.1 machine (pretty clean) to 11.3. After the upgrade, the NVidia graphics no longer worked, but more importantly, eth0 was not bound to my Intel 82566DC gigabit ethernet controller. I fooled around in yast network devices long enough to know that everything there is configured correctly. The Yast message at the bottom of the Network Settings screen says:
"Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details."dmesg output shows nothing related to networking. The boot screen shows:
Setting up (localfs) network interfaces:
lo ...
Waiting for mandatory devices: eth0 __NCS__
29 28 27 ... 1 0 ... failed
eth0 no interface found ... failed
[code].....
Any ideas here? I've googled till my fingers were tired and all I've found are references from folks with real hardware issues. This machine worked fine for me under 11.1. Now I can't get 11.3 to bind the nic.

I have a strange problem. An old PC is my home server. On the PC I had in the long past 2 NICs. For the last year or so, I had only one NIC installed, a Compex with 8139too module which run just fine. After the upgrade to 11.4, 32bit of course, with zypper dup, I saw that I had no internet and no network connection to the server. So, I logged on the server and found that rcnetwork could not start the eth0 and eth3(!). OK, a mistake I thought. Enter Yast and solve it. Unfortunately, yast reports 2 cards! I removed all of them, rebooted but nothing. lspci reports 2 cards, while I have NONE installed on the motherboard!hwinfo --netcard the same! yast the same! So, the OS "knows" that I have 2 NICs, while I definitely have none!
Checked if /etc/udev/rules.d/70- had any left data from the past, but the file was empty. Checked the /etc/sysconfig/network/scripts nothing again.In principle, the openSUSE 11.4 believes that I have 2 cards (and with wrong MACs, obviously) and I cannot make it rescan the PCI bus to find that I have nothing! I am sure that some garbages are left somewhere but I don't know where to look at. it is very critical to have that server but on-line and in my LAN.

I am running 11.3 with Remote Admin(VNC) turned on. This has installed TightVNC.I also have also enabled xinetd to manage the startup of new (incoming) VNC requests.All this is working just fine. So, what's the problem, you ask? Its that missing Shift+3 symbol. To reproduce, I run TightVNC (viewer) from a variety of clients (Win & OpenSUSE) to a number of OpenSUSE servers with xinetd managed VNC services enabled. The Xvnc sessions start and the clients display the KDE log-on screen. You will notice that in the username field that the sign is not displayed.
I have run a parallel VNC service (is it Xvnc or vncserver?) which gave me a twm session. It also is missing thesign, so I conclude that it is not KDE that is causing the problem?Secondly, a scan throughog file produced by the parallel VNC service shows:Code:KbdAddEvent: unknown KeySym 0x3a - allocating KeyCode 92 Has anyone any suggestions on how I can get my pound sign?

I can access my NAS box with telnet but the file I am looking for is not in the expected directory. Of course I could go through all the directories using ls -a but that would take days. Is there a command I can run to look for the file for me using the telnet console?

I've just re-installed 11.04 and noticed that my RAID array does not appear as an entry under "Places". In the previous installation, and in the LiveCD boot (which I'm using now), it appeared as en entry which I could click on to mount. In Disk Utility (and Gparted I think - not 100% sure) I can see both hard drives, and I can see the SIL controller that they come under, but I'm just not getting the array showing up in "Places", and the array checks out OK in BIOS. Using the Live CD, the array appears as an entry in /dev/mapper but when using the main installation all I can see in this location is "control".

sudo apt-get install xorg gnome-core gdm gnome-applets gnome-system-tools gnome-utils ubuntu-artwork compiz-gnome firefox sysv-rc-conf

I'm having trouble pinging localhost, specifically, pinging localhost when I'm not connected to a network. When I try it keeps telling me the operation is not permitted:
Code:
matt@mubuntu:~$ ping localhost
PING localhost (127.0.0.1) 56(84) bytes of data.
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
if I connect to the network, start pinging then disconnect it continues pinging. Google seems to think it could be something to do with my iptables setup:
Code:
matt@mubuntu:~$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
[code]....
When not connected to network
Code:
matt@mubuntu:~$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
But as far as I can tell there isn't anything in there which would stop me connecting to the localhost (I also can't connect to my local apache instance when offline)... (It's worth mentioning that a couple of weeks ago I had the pc setup to share it's internet connection with a laptop, ala this guide, however I've since disabled the iptables rules and disabled ip forwarding.)

I'm working on setting up access for our developer via Telnet, we are on a local network behind a physical firewall. I set up the standard Telnet service for Fedora15 and from localhost I can login via any user and root.... However I cannot login from another terminal on the LAN, even though I can ping and FTP to the fedora15 box. I added the firewall rules for telnet, that did not work, so I disabled the firewall, still cannot get a connection via port 25. I feel either port 25 is closed in another manor or the telnet is restricted to the localhost.
Also I cannot login to root to configure the Firewall Desktop GUI, only standard users, is this an issue? I also cannot login to the console as root even though I use the correct password.I can only su to root and sometimes it is a PITA. There must be some settings to clear these issues up...

a while ago, Network manager kept on messing around and disconnecting me etc. I attempted to setup a static network (wired) and since then, everything worked fine. I also have apache running and have had no problems with that. I know there were some apache auto updates this week but I have been doing no dev work. I went to check out one of my local sites to do some work yesterday and there was just nothing happening.
I checked everything with apache, it is all running etc. I have stripped back the conf files to be clean and fresh and netstat is showing apache as listening on 127.0.0.1:80 as it should for a single default site that I have on there now. BUT if I try to ping localhost by name or by 127.0.0.1 I am getting "Destination Port Unreachable" Since I have been trying to fix this, I have been trawling the internet to try and clean up my network setup from scratch (I have also had problems with https sites that has turned up to be the MTU setting on my eth0 interface) but to be honest I am not sure exactly what should be set between ifconfig, route, netstat and apache. should I be able to ping localhost independantly of running apache2 (i.e if it is stopped) or would a successful ping rely on apache working correctly.
