OpenSUSE Network :: VNC - "Failed To Connect To Server"
Jul 9, 2011
On one machine I have OpenSuSE 11.4 and the other is Windows 7. From OpenSuSE I can connect to the Windows 7 machine running Tight VNC using KDRC and no problems. But I get a message of 'Failed to connect to server (192.168.1.1)' when I go from the Windows machine to the OpenSuSE machine. ON the OpenSuSE machine, the firewall has VNC and VNC Sercver allowed in the firewall. In the Remote Administration, 'Allow Remote Administration' is checked and Open port in firewall is also checked. Why can I not connect? Also, how do I set what the password is on the OpenSuSE machine?

I'm having a real problem with intermittent ssh disconnections?It's the same thing regardless if it's over ethernet or wireless, and nfs shares don't have any problems at all.

I have an openSUSE 11.2 and I was trying to connect to a FTP server from Dolphin application but it didn't work. (I used ftp://<IP ADDRESS> in the address field)
From CLI or using FileZilla I can connect to that server.
What could be the cause of this strange behavior?

Upgraded two machines to 11.3 in the past 2 weeks. NFS is broken on both, in different ways. The problem I'll mention here is that the nfs server is running, but clients can't connect.
The server is running:
tinderbox:~ # /etc/init.d/nfsserver status
Checking for kernel based NFS server: idmapd running
mounted running
statd running
nfsd running
It has a valid export list:
tinderbox:~ # showmount -e
Export list for tinderbox:
/usr/local/share/common 192.168.1.0/24
The export exists:
tinderbox:~ # ls -lR /usr/local/share/
/usr/local/share/:
total 4
drwxrwxrwx 2 root root 4096 Jan 2 12:10 common
/usr/local/share/common:
total 0
-rw-r--r-- 1 root root 0 Jan 2 12:10 test.txt
But attempts to mount the export are unsuccessful, both from the local machine:
tinderbox:~ # mount.nfs 192.169.1.200:/usr/local/share/common /mnt -v
mount.nfs: timeout set for Sun Jan 2 12:14:19 2011
mount.nfs: trying text-based options 'addr=192.169.1.200,vers=4,clientaddr=192.168.1.200'
mount.nfs: mount(2): Connection timed out
mount.nfs: Connection timed out
...and from an OpenSUSE 11.0 machine.
moira:~ # mount.nfs 192.169.1.200:/usr/local/share/common /mnt/tmp/ -v
mount.nfs: timeout set for Sun Jan 2 11:52:17 2011
mount.nfs: text-based options: 'addr=192.169.1.200'
mount.nfs: Unable to connect to 192.169.1.200:111, errno 110 (Connection timed out)
mount.nfs: mount to NFS server 'rpcbind' failed: timed out, giving up
I've had NFS running on my local network for over a decade, and never had problems like this before.

until 2 weeks ago I had o.S11.3 on both my Siemens and Asus laptops. I have installed NX No Machine. ( I know it's not open source,I am using the free version). With commandline ( root) /usr/NX/bin/nxclient I was able to connect to the other machines. I got Qt: Locales not supported on X server, the NX menu popped up and I was able to connect by inserting resp codes. After fresh install of o.S.11.4 on the ASUS the commandline (root) answers:
xlib: connection to":0.0" refused by server
xlib: No protocol specified
nxclient: cannot connect to X server:0.0
The ASUS can still be reached from the other machines (one with o.S.11.3,the third one with o.S.11.2 ) SSH ( Lan)connections are all working forth and back between the machines, even to and from Win XP, however only from Win 7 on the ASUS, but that's a Win7problem. Comparing the installed xorg-x11- server-extra : on o.S. 11.3 Additional X servers ( Xmdx,Xephir,Xnest,Xvfb ) ,on o.S.11.4 the Xvfb is missing, might that be the reason?

So a while back I was able to mount a directory from my OpenSuse server as a NFS on an Esxi server. After restarting the Esxi server, the NFS became inactive and I was unable to remount it. The error given was that the Esxi client was unable to connect to the Suse server. I was looking into the showmount -a command on the Suse server and it showed the mount point on the Esxi server. Could this be causing the Suse server to reject new attempts to mount the directory? What else can I try to fix this problem? Also I should note that both servers can ping each other.

I have steup samba shares on my Susi pc. I get to the point where the server asks for a password for the user I have on the Susi box but when I enter the password it fails to connect. tried to add the user, password and enabled the user in the samba conf file. But not sure where it should appear I give below the smb.conf file:
# smb.conf is the main Samba configuration file. You find a full commented
# version at /usr/share/doc/packages/samba/examples/smb.conf.SUSE if the
# samba-doc package is installed.

I have x11 forwarding enabled in /etc/ssh/sshd_config on a suse 11.2 32 bit box running kde I can open x apps on a windows machine using xming and putty just fine, but when I boot the same machine into suse 11.2 64 bit using kde and try using konsole I get: cannot connect to x server
The command I'm using to log in is: ssh -X -l username host I doubt the problem is with the server I'm logging into or it wouldn't work in windows, not really sure what to look for as I've never had a problem using x11 forwarding from a linux client before only windows ones

I am running openSuse 11.2 on Acer Turion64 x2.
My wireless card is "Atheros Communications Inc. AR2413 802.11bg NIC (rev 01)".
For some reason, networkmanager can not connect to network at all.
In NetworkManager log, it is showing "kernel: [ 28.002378] ADDRCONF(NETDEV_UP): wlan0: link is not ready".
I try to find out why it can not connect to network by using knetworkmanager.

I've tried to get an opensuse box I have to share a directory via NFS. I've failed each time, but I thought that the third time, I'd enlist some help from the forums, if I could. how do I know that the nfs server and not the client is the problem? Short answer is: I don't! That's why nfs (and many netwrk problems) are laborious, you're troubleshooting needs to take place at both source and desitination. Next question, what do I have set up so far? Well, I did download the nfs server kernel stuff (two months back) and /etc/init.d/nfsserver start seems to get set up OK. No errors and the daemons nfsd, idmapd, mountd area all running. So, I *think* that part is OK. I have the share set up properly in /etc/exportfs and have "exportfs -r" it.
OK, now onto the trickier stuff: the client and iptables. On the client pinging to the nfserver box is perfect, and I have rpcbind running. the reported error is "mount.nfs: mount system call failed" though from experience nfs errors don't mean a whole lot.However, I will go off and check now and see if I need a mountd running on client-side too.Then there's iptables .... ouch, that could be a long and painful trek. I don't see any specific ports being blocked, and it's the iptables that the default v11.2 opensuse came with. I did turn them off and the problem was the same, so whether wishfl thinking or not, I'm hoping it's not an iptables issue.

I was working recently on a perl program on our ftp server (box is running SuSE, I belive v9.3) designed to email a warning if the mountpoint to our backup machine could not be mounted. A couple of other programs, month-end critical, took me away from that for a while. I got back to it today, only to discover that I cannot even send the messages anymore (before, I could send, but I was having trouble interpreting the results I was sending).
The program is using MIME::Lite for its mailsending function. The actual error message I am receiving is
Code:
Failed to connect to mail server: Invalid argument at ./organize_bks_2 line 174
The line in question is the actual $msg->send command.
I have good reason to believe that the environment for this has changed; during the time I was working on other projects, our office phone setup was replaced and refined with an ethernet-connected setup installed by the company that provides our mailing services (and presumably network services in general, although I do not know this for a fact). I know that we were having email troubles with some of our month-end scripts after that, which required our main server's DNS values to be changed...but those errors were not the same as the one I am getting on this machine.
Is this simply going to be as easy as changing the DNS settings on our FTP box, and if not, where is the best place to start digging for more information?

If your machine is connected to the Internet, you'll probably want to disallow ssh password authentication (which is advised but not mandatory). Edit the /etc/ssh/sshd_config file and change/add the following lines:
PasswordAuthentication no
AllowUsers nx
Don't forget to restart the sshd daemon after making that change: service sshd restart I already have PasswordAuthentication yes in my file as I need it to login to the server through ssh. Do I just skip that line and only add AllowUsers nx mynxuser at the end? Also, I followed the rest of the manual and when I tried the client on Windows it failed: I put in a user and password to login but shouldn't it be using the key instead? I think the problem is related to the above due to:
Quote:
NX> 203 NXSSH running with pid: 1428
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files

I enabled remote desktop on my Fedora core machine.
SELinux is disabled, as is iptables.
I used UltraVNC to connect and it worked.
However, after I came back overnight, I tried to connect and it failed.
I received a "Failed to connect to server"
Found that the machine had rebooted.
How do I get it the Remote Desktop function to start as a service? I am new to Linux.

Im having some problem with my DNS. We are using a Linux web server as one of our web server which runs some live websites.When I trying to get the status of the DNS (NAMED) it comes the following error :
The same error appears when Im trying to apply any changes on zone level for a selected doamin in WEBMIN. (Basically can't apply changes)
WEBMIN > Servers > BIND DNS servers > click a selected-domain.co.uk > Apply changes
NDC command failed : rndc: connect failed: 127.0.0.1#953: connection refused

I've been using synergy on Ubuntu 9.04 and windows xp.Synergy 1.3.1 on both machines.My problem is that the server keeps cutting out. It seems to happen a lot when I watch flash videos on the server machine (ubuntu). This is what the server side looks like:
Code:
NOTE: synergys.cpp,500: started server
INFO: CServer.cpp,1141: screen "server" shape changed
NOTE: CClientListener.cpp,127: accepted client connection
[code]....
I dont think I usually get disconnected when doing other tasks. Mostly only when watching flash videos. Sometimes it doesnt automatically reconnect, and I have to kill synergys and restart it.

After installing 11.4, I need to type in the command to update the firmware for a broadcom wifi adapter. Then I needed to reboot, twice, before the system knew to use the adapter (where the adapter wifi light goes from orange to blue).
Then I needed to add my wireless network and type in my key. But the key does not take. If I click on my wireless network icon, it just re-asks for the key and does not connect nor give any other message. Network icon continues to display no connection.
So I need to reboot again.
When the system starts again, the adapter is blue, I click on the icon for my wifi network and it connects without asking for my key and I can then set to start my wifi by default.
Now my wifi works fine.

I have the wep key in there and i even made it visible to make sure.

I installed OpenSuSE 11.3. The only "extra" package I put in after the install was VirtualBox-ose. The firewall is disabled. I gave the machine a static IP address. I can get to the Internet from the machine. I enabled sshd to start on boot with "chkconfig sshd on" and also verified the service is running on the machine. I can ssh user@localhost from the machine as well.
When I try to connect to SSH from another machine, I get a connection refused. I verify that the firewall is down. I also try to get to VNC -- same problem: Connection refused. I ping the machine for fun. If I try to SSH again, it sometimes gives me a logon? I would check the server logs for the connection refused, but I wouldn't know where to look. I started in /var/log/messages, but nothing seemed to jump out there. I also find it strange because I can RDP to a windows guest running under VirtualBox. The Windows guest uses Bridged Network and DHCP.
I also find it interesting that I sometimes type a "ping google.com" from the 11.3 box and it will just hang - no output. Then I open firefox and get to the internet. All of a sudden, ping starts to give output. Could this be a neetwork card issue? A configuration issue? I don't know where to start.
