I'm having a little problem here. That, or I'm missing the obvious staring me in the face. I have this file server, called toad. I nuked it's system disk, reorganising the partitions and upgrading to openSUSE 11.3 x64. I installed vsftd with "Yast FTP server", and the config looks OK. I even compared it with that of another machine. But when I try to connect, this is what I get:
ftp> open toad
Connected to toad.geuens.org.
500 OOPS: could not bind listening IPv6 socket
I'm prettige sure IPv6 is deactivated. The firewall is disabled on both machines. I've looked this over again and again. Can't find it. It's not the connecting machine, I've tried from another.
I'm working with OpenSusse 11.2. I installed and activated the NFS server via yast2. I exported the relevant directory via yast2 (NFS server configurastion) I'm trying to setup my Linux target to boot via NFS. The kernel boots up but fails to mount the file system. When looking on a capture from ethereal it can be found that the NFS server return error when client try to mount the /nfstest directory from this server. The returned error is 13
im on node1 when i type the command ssh node2@ip the terminal hangs up a bit then an error message stating that connection timeout but here is a thing: i cant ping to node2 but i can terminate the ping manually using ctrl+c when i terminate the ping usual message appears stating 10 packets transmitted, 100% loss
ps: when i go to node3 and ssh to node2 it works fine and also i can ping from node3 to node2 very fine. and the firewalls are down at all nodes -all wired connection over a switch
I am running vsftp on one of my systems and when trying to connect to it it errors out with this: vendion@Loki:~> ftp 192.168.1.100 Connected to 192.168.1.100. 500 OOPS: could not bind listening IPv6 socket
I have tried stopping the firewall and even disabling IPv6 nothing changed, any clues as to what is going on?
I'm using Internet connection through local network, receiving white (global) IP, route, DNS with local DHCP server. Lately I noticed that my Ubuntu gets ipv6 autoconfiguration from ISP router, receiving global ipv6 address and automatically adding ipv6 route. I can access Internet resources using ipv6 connection: I can ping inet resources using my ipv6 global address and access, for example, ipv6.google.com or URL..
How can I share ipv6 connection to my home network? Using ipv4 it's easy, I just can use NAT for this. But if I understand correctly, in ipv6 there isn't such thing as NAT, because there is no limit in ip addresses.
I use DNS on my server as a chasing DNS so its not fully configured. I seem to be having trouble with IPV6 addresses. I'm guessing this is linked to the 6to4 tunnel I have set up to my windows box, but I'm not really sure.
I am trying to Setup citrix ICA client 9 on Ubuntu 9.04 Server. I installed it very easily and I am not getting any lib error also. But when I try to connect to the citrix server, it fails with a pop up saying "Error in Network Connection Network or Dialup connection may be preventing ......" This is driving me crazy from 3 days. My project is to check the feasiblity of a Linux desktop
I have a service on my Suse 11 server which runs an ssh command (using openSSH) on another box.The output below is returned, but legitimate output is also returned as if the command had executed successfully. For example, the service executes an ls command through ssh, gets the error below, but also the contents of the remote directory as output. This is a problem because the service retries the command until it receives no error. I have been unable to replicate this manually from the command line. Does anyone know what might cause this or what this error really means?
I'm extremely new to SuSE Linux. I wanted to move away from Windows and so I decided to reload my Desktop with SuSE linux.I have had no trouble until now. I'm trying to connect to my work VPN connection. From my laptop (which unfortunately is Vista) I'm able to connect without any issues. However, when I tried out the KVPN application on my SuSE linux, it just doesn't work. I get the error: Authentification has failed. As a side note, when I type ping google, the packets are received 100% but when I ping my company address, no packets are received. Hope this info is useful.
(I'm probably going to have my forum account revoked due to excessive usage ) I'm setting a VPN connection on openSUSE 11.2. Using the networking icon on the tray I add a PPTP connection, set it up but I receive a message 'VPN connection failed'. Googling it up I tried changing a setting called 'refuse-eap' to 'yes' but it doesn't seem to work. Here's the result from the log file:
I decided to enable dual stack on my home 11.3 machine and play with IPv6. I use ifup to assign static addresses to eth0. FYI here are some things I found:
1. YaST doesn't seem to support associating IPv6 addresses to interfaces, it complains that the address is invalid. However you can edit /etc/sysconfig/network/ifcfg-eth0 manually and specify it like this:
and when you restart the networking you will see an additional IPv6 address associated with eth0. Fortunately YaST doesn't mangle the entry when you look at it, but you can't edit it.
2. The SCOPE qualifier is documented in /etc/sysconfig/network/ifcfg.template, but seems to have no effect. Site local addresses in IPv6 are supposed to start with FE[CDEF] according to this:
The TCP/IP Guide - IPv6 Special Addresses: Reserved, Private (Link-Local / Site-Local), Unspecified and Loopback
Once bound, you can connect to services using the IPv6 address just like normal. You have to use ping6 instead of ping though.
I added an AAAA record to my nameserver and that seems to work. Whether the client software tries the IPv6 address varies. It depends on whether the software asks for the AAAA record and uses it. It seems my web browsers don't. I'm not surprised, since few people have IPv6 tails from their ISP. I'm going to look and see if there is some browser setting I have to adjust. I also have to figure out a way of making sure that only LAN destinations use IPv6.
I have set up an ubuntu server running PPTP Server for VPN connections. I can successfully connect from a laptop within the LAN, but taking that same machine to an internet connection and trying to connect back in does not work. The only difference is that when I connect from within the network, I am obviously using the server's LAN (non-routable) address, and when I am connecting from outside the network (from Verizon Business DSL ), I am using the Comcast connection's static IP address.
I have a static IP address on a Comcast Business Class internet connection. Router is set to forward pptp and GRE ports.
Works: VPN Server <- Laptop iPhone -> Internet -> Router -> VPN Server
Does not work: Laptop -> Internet -> Router -> VPN Server
Here is the weird thing. I have an iPhone that connects flawlessly every time through it's AT&T data connection. The laptop however, gets to "verifying username and password", and then returns error 619. It seems that there is an issue only when going through the router using the PPTP client built into MS windows.
I have local and remote networks that have various printers. I can add any printer (local or remote) to any PC, except for one PC that's refusing to allow remote connection (it used to, but doesn't now!). The problem PC has two printers connected and work OK as a local printer, but both display same problem when attempting to connect from any remote PC via YaST. Using 'Connection Wizard> CUPS Server' connection method requires IP address of remote PC and printer name. But if I correctly select either of the two printers I get an error message:
"PING 192.168.1.149 (192.168.1.149) 56(84) bytes of data. 64 bytes from 192.168.1.149: icmp_seq=1 ttl=64 time=1.12 ms
Both printers are set to 'Accept Print Jobs' and 'Share Printers> Allow remote access' permits all networks to connect. why this PC is requiring the root password?
does opensuse 11.2 come with IPv6 enabled by default? where in the gnome gui can i access these settings?
Edit-i went into the gnome network manager applet and i cant find any IPv6 settings for any of my used connections-ethernet, wireless and VPN connections all seem to only IPv4. Can anyone else confirm that opensuse 11.2 uses only IPv4 on its network connections?
I had this issue with Fedora Core 13, so I switched my laptop back to OpenSuse and continued to have the problem. I can do a host lookup for software.opensuse.com and I get a correct response ... Code: linux-edxs:/etc # host software.opensuse.org software.opensuse.org has address 126.96.36.199 linux-edxs:/etc # host download.opensuse.org download.opensuse.org has address 188.8.131.52
Firefox works. Thunderbird finds my mail servers just fine. SSH works. But then when I try to do anything involving software updates or installation, I get ... Code: linux-edxs:/etc # zypper update Retrieving repository 'Updates for openSUSE 11.3 11.3-1.82' metadata  Download (curl) error for '[URL]': Error code: Connection failed Error message: Couldn't resolve host 'download.opensuse.org'
I've seen others here post queries about this, and I'll tell you what it was in my case: our DSL modem's DHCP server returns its own IPV4 address as the DNS server. When I looked at /etc/resolve.conf, I saw "nameserver: 192.168.50.254" on the last line -- the IPV4 address of our DSL modem. I manually inserted "nameserver" lines for our ISP's two actual DNS servers, and everything magically started working. Why this should confuse some software under Linux, but not other software, is a mystery. It also seems to be Gnome-specific (I didn't have this problem with OpenSuse 11.3 and KDE 4).
Ask if they're using Gnome, and ask them to check resolve.conf. A lot of DSL modems and home/small office routers return their own IP address (i.e., the same as the gateway address) for the DNS server on a DHCP query. The solution is to manually edit resolve.conf and put in your ISP's DNS server addresses manually. Incidentally, just my opinion, but Network Manager needs to make this an option. Under Windows, for example, you can select "automatically assign DNS" or you can enter them manually, even if you're using DHCP. It'd be nice if Network Manager permitted that.
My problem is that the Mailserver in OpenSuse 11.1 (postfix, amavisd, spamassassin, clamAV en Razor) can not recieve e-mails, outgoing is ok. The problem started when I added 2 new users to de LDAP-server connected to Postfix.Some users can login, but most of them are getting the error: cant connect POP3 connection refused port 995.
it's a couple of weeks I can't perform YaST updates from my openSUSE 11.2. The reason is that YaST wants to connect to repositories "only" through IPv6, but my network doesn't support it. I quoted only because I suppose it prefers v6 over v4, but it keeps trying to connect without switching to v4 or returning error.
Even if I disabled IPv6 from YaST/Networking/Network Settings, I still have a local scope address. I connect to Wifi using KNetworkManager. The TCP/IP stack should know that if an interface has a local scope v6 address and a global v4 address, it's a bad idea to keep trying with v6. Italian mirror, garr.it, of openSUSE repository both has v4 and v6 addresses. If I try to ping opensuse.mirror.garr.it I ping v4, but if I try to telnet that host on port 80 it tries to connect to v6. Same if I try to connect with Firefox.
How to tell Linux that I don't have IPv6? I'm connecting from University of Naples wireless network. While unina has IPv6 via GARR's Teredo tunnel (2001:760::/32 as I remember), it doesn't reach students' network because DHCP server doesn't release IPv6, nor Zeroconf obtains one. I just would like to use classic IPv4 until, at least for now.
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.
uname -a Linux server-1 184.108.40.206-5-default #1 SMP 2009-02-28 04:40:21 +0100 x86_64 x86_64 x86_64 GNU/Linux Code: route -A inet6 Kernel IPv6 routing table .....
IPV6 gets more and more interesting. YAST is failing to connect to the repositories. I have disabled ipv6 in several ways but none of them work or YAST (also Konqueror) seems to do it's own thing. I have managed to get Firefox to work see my "slow internet seems to be down to dns post" made earlier today. So as a check on the YAST problem I loaded each of the repository addresses into Firefox and lo they all connect without any problem at all. So it seems that the YAST problem is down to IPV6
In order to disable ipv6 I initially added ipv6.disable=1 to the end of all of the bootloader APPENDS. More recently following up further info on here I added a couple of lines to /etc/modprobe.d/99-local.conf. These were: alias net-pf-10 off alias ipv6 off This doesn't work either.
Maybe of use to others - It seems it's possible to see if IPV6 is active by typing the following into the command line: ip a | grep inet6 I'm told if it is active lines will be output? So just what do I do to disable it in YAST and I hope in Konqueror too? It's beginning to look like it is enabled or disabled at the app level according to the Firefox fix.
I've had a hell of a time with this and now all but YAST2 are ok. Going back some time to 10.0 this could be used to disable it very completely.
open terminal and run echo "alias net-pf-10 off" >> /etc/modprobe.conf echo "alias ipv6 off" >> /etc/modprobe.conf
restart computer. Has anyone used this on more recent issues even 11.4 and are there any repercussions?I assume that the inverse will but it back on ie off's just become on's? I will be using cups when I install my printer which is one concern and I am not at all sure that modprobe will do anything anymore?
I also recollect that there is a command to cause the kernel to effectively reboot which would save restarting. Can't remember what it is. Maybe some one can refresh my memory.
I got connecting to our NAS over NFS working perfectly. Direct NAS Reading & Writing - How? But on Saturday I found out it had stopped working. For no apparent reason, not straight after an update either I don't think. When I manually try to mount --verbose:
mount 192.168.100.14:/IHL /mnt/IHL --verbose mount: no type was given - I'll assume nfs because of the colon mount.nfs: timeout set for Tue Jul 6 14:48:32 2010 mount.nfs: text-based options: 'addr=192.168.100.14' mount.nfs: Unable to connect to 192.168.100.14:111, errno 111 (Connection refused) mount.nfs: mount to NFS server '192.168.100.14:/IHL' failed: System Error: Connection refused
Corresponding fstab line that used to work just fine. 192.168.100.14:/IHL /mnt/IHL nfs auto 0 0 For now, I can drop back to Samba but this is a PITA as I can't open OpenOffice documents and write to them directly on the NAS. The fact smb://192.168.100.14/IHL works proves networking wise we're cool too. There is no firewall between this PC and the NAS, the NAS is instructed to allow my PC's LAN IP full access. OpenSuse's software firewall has been told to allow NFS Client too. Why would this setup break out of nowhere? How can I debug this best? I see nothing relevant in /var/log/messages How can I get it to work again? A hopeful reboot didn't do its usual wonders...
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).
On our Home LAN, we have several different SuSE machines running. Now, I have run into a problem which I cannot solve myself. One of the computers (a 11.2) just doesn't receive any IPv6 lease from the main router. The router has radvd running and distributes addresses to the other computers just fine. The network card on the box ist a
My ISP offers the service of native IPv6. So my ADSL router provides me with a local and global IPv6 address. However after a reboot it takes minutes to finally see the global address when using "ifconfog eth0". During that time I can't do a ping6 to an external server, which seems logical. So I waited several minutes, but no global address. After that I started a KDE session, went back to the console(<Ctrl>+<Alt>+F1) and now the global address was there. Is this normal behavior or should I file bug report?
I installed 11.3amd64 as a VM under Vista/VMWare Player - all worked fine. I have now installed it as a physical system. It nstalled cleanly BUT during first boot it could not access the repos. With each repo it gave the message
- download (curl) error for (repo) - error code connection failed - error message could not resolve host (repo)
This was followed by a message box containing
- UI syntax error - no widget with ID 'contents
Firefox could not access the internet (cannot find server) until I disabled IPV6 (I used about:config), now it works fine. I think the repos problem is because of IPV6 - I usually have trouble with IPV6. I tried disabling IPV6 with the following (How To Disable ipv6 on SuSE Linux | Linux Poison)
I can make a connection to the vpn server, the connection starts, but nothing happens! My IP address remains the same as previous! There is nothing added to my Knetworkmanager, I'm a beginner I should use a pcf file for my vpn connection. I use it properly, I'm sure because the connection starts and an icon is added to my panel and remains until I disconnect.
I checked it via ifconfig -a, the last part (which is for vpn) is:
I am not so experienced with networking in Linux. I've successfully installed Red Hat Linux Enterprise 5.2 on a VMware host. When I issued nslookup command, it returns "connection timed out" error as follows:
Code: [root@rac1 ~]# time nslookup rac1 ;; connection timed out; no servers could be reached real 0m15.038s user 0m0.000s sys 0m0.000s
My questions are: (1) Is that error normal? (2) Is there a way to decrease the 15.038s value? rac1 is the local hostname, so why it takes all that time to resolve it.
Following info may help: Code: [root@rac1 ~]# hostname rac1.mydomain.com [root@rac1 ~]# cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost #eth0 - PUBLIC 192.0.2.100 rac1.mydomain.com rac1
