OpenSUSE Network :: Can't Get Ssh To Work On One Opensuse 11.2 Machine
Jan 12, 2010
I have three machines with the same configuration. ssh and SFTP enabled on all three and I can see all three from the network. I can also ping all three. Here is what I get with the ssh debug command on the problematic machine:
linux-csp7:/home/ines # ssh -vvv firstname.lastname@example.org
OpenSSH_5.2p1, OpenSSL 0.9.8k 25 Mar 2009
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug2: ssh_connect: needpriv 0
I have an appliance called my_appliance.raw. To start the appliance locally, I use:
After that I would like to ssh into the guest from the host but just the ssh command doesn't work. firewall is disabled on guest. the ip I use is the one that ifconfig shows when I run it on guest. sshd is running.
First off How do you disable IPV6 access on all connections used on the pc-is there a way to test for ipv6 connectivity?
Secondly how secure is a default opensuse 11.04 machine out of the box? should i be making some changes to the default configuration?
Thirdly what does the default firewall settings do? on my network i use my wpa2 psk aes connection via my local wireless network-in the event that some can hack into my wireless would the opensuse firewall prevent direct access to my pc from a attacker on the same wireless subnet?
Fourthly when does opensuse 11.04 go out of date? in a year from now?
This is a thread I've moved over from the install forum and is hopefully more focused. Sorry if I have violated some protocol. Problem I have a new machine build configured to dual-boot Windows 7 and OPENSUSE 11.4. Network performance in Windows is very good but network performance in OPENSUSE is very poor.
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.
Recently loaded 11.3 onto a virtual machine, however none of the network settings will allow me to connect to the internet. First time Ive had this happen, other distro's Ive experimented with connected with no problems. I recall seeing a similar topic some time ago (dont remember if it was here or another forum), but at the time, there had been no fix. Anyone know if this has been fixed?
I had an OS 11.3 machine running as an Nis server with Nfs, also providing dns, squid, samba shares and running apache
Internet connection provided by a netgear router at 192.168.0.1, server at 192.168.0.2, clients at 192.168.0.3, 192.168.0.4, etc. The clients all being configured to use the server for dns the squid running on it for their proxy, logging on with Nis using the exported server's Nfs /home share as /home on the clients
Everything was setup through Yast with some conf file editing being done later for samba and apache and all working brilliantly
I added another network card to the server machine and set it up as a router, where they will be placed once ready the router providing the internet connection doesn't have gigabit ethernet
So I figured if I had gigabit cards in the clients and a gigabit card in the server set up for the internal zone and providing routing, then the clients using it as their router the local stuff would be more responsive, especially as they are using an nfs share for /home
I set the clients up to use the server at 192.168.1.1 for their router and changing their own local ip addresses to suit, i.e. 192.168.1.2, 192.168.1.3 etc and rebooted
Nis and nfs were no longer working, so I logged on as the local user, ecky, who's home directory isn't in the nfs share but at /ecky, the internet connection worked fine and so did everything else, dns, proxy, etc
I tried changing the nfs share and nis server to the internal card's ip, 192.168.1.1 and that didn't work either
Samba shares work at both 192.168.0.2 and 192.168.1.1, so my problem is that nis logons and nfs mounts don't work from either address
I've tried to give as much info as possible on what I've done without being too confusing ... don't know whether I succeeded
Darned annoying cos it took me a day and a half to get the gigabit card to detect properly in one of the machines...
I have had a notebook with an ethernet plugged in cable before, sent a signal through the cable by resetting my router, and it switched my notebook on from cold. My question is, is there a way of doing this using a remote desktop client. Ideally, I would like a machine switched off at home running suse linux/windows, then have a client computer sent the remote request, this in turn activates the machine, which boots and then gives the rmote client control.
So here is what I am trying to do. I want to connect my Open Suse 11 machine to the internet. I am almost there.
1. I configured my network card and eth0 is up.
2. I configured my DSL with user name and password and I am authenticated.
3. An IP address is assigned to me and the DNS servers are retrieved.
However I cannot ping or visit any website I use the YAST automatic configuration and kinternet to connect. Here are the gritty details
I do see that kinternet has trouble reading /etc/resolv.conf. It says 'permission denied' although read permissions are set on both /sbin/route and the path that it links to. This should not matter however since the existing entries are already there and valid. I also tried to turn off the firewall suspecting it could be a problem.
So I am being authenticated successfully ( verified with the logs ); assigned an IP; the route seems ok; firewall seems ok. But I cannot browse or do internet things I have been tweaking settings for 3 days now and all seems in vain. Do enlighten me on what I am doing wrong. I bet its something silly that I overlooked. I have had success configuring the same thing in red hat linux and browsing the internet without trouble. Is there something OpenSuse specific that I am missing ?
I am starting a MCSE course and part of it is to create and configure a domain etc etc I have done this and all my windows XP and 7 machines on my LAN are now functioning as part of the domain just great.
Unfortuntely, I have several Open suse machines which are currently not part of the domain yet (they are in a basic Workgroup).
get these computers onto the domain so that a user can log on using their domain credentials and I can apply security policies and what not?
regarding a remote connection from my workplace to my home system. On my home a have a connection to the ISP and the provider is allocating a dynamic IP to my router. How can I connect from my work computer to the home computer? There are other application or other stuff for making this possible?
I have been working on this for about 4 hours so I am extremely frustrated. I am trying to access windows shares from my linux box. I will worry about getting my own data shared afterwards.
I was having the authentication problem described by swerdna's sticky, and it was solved by the upgrade. However apparently that is not the main problem. samba is trying to use my ISP's DNS to resolve the internal network names. I have a vague conceptual understanding of WINS and NetBIOS - but Windows does this without any extra steps. Do I need to configure my machine to also act as a WINS? how do I do that? In my searches I found a thread about "why do windows to linux users give up?" this is why.
I'm in the situation where I'm trying to create 2 private networks using ESX server, all behind a NAT router (static ips are used). I used an openSuse11 vm as a router and was able to configure it so that a machine on one private network was able to access the public network. The problem I have now it that I need to be able to access a machine on the private network from the public network using a different set of IP's.
So if a machine in the private network has an IP of 10.1.0.222 I should be able to ping it using 10.99.0.222 or some other IP. I have never done this before and after reading up on iptables and linux routing I feel more confused than before. Is it possible to add IPs to eth0 (public) and have them mapped to machines on a private network eth1 or eth
I have created a small network using Win7 (not a home network, it's a workplace network), but cannot see the Win7 machine from my Linux box (openSUSE 11.3 32 bit). I am getting the error message "Empfangen der Speicherliste vom Server ist gescheitert" ("couldn't receive storage list from server" or so), wenn I try to connect via "Locations -> Server -> Windows Network -> 126.96.36.199 (which is the Win7 machines local IP address).
Disabling the firewall doesn't help.
My setup is a DSL router to which all my computers are connected.
Despite searching the inet for hours I couldn't find a solution.
Another problem is that from the Win7 machine I can only access the public folders on the Linux machine using the root login (not the user I used to make the folders public).
I set up a Samba server on my openSuSE 11.2 machine and I can connect to it locally with the local ip and with my actuall ip. My friend however cannot. I tried to have him ping my ip and that wouldn't even work. I'm confused and wondering why it doesn't work. We share a lot of files and this would make both of our lives much easier.
It took me a while..But I finally got samba to be a pdc. I was able to join a test xp machine to the new domain samba made. That part worked well. In my Swat I added a samba new user and password. restarted samba etc.. Then tried to log in from the xp with the new user name as the password. As I hit enter im waiting for it to log in..the XP machine reboots. It seems to do that ever time I try. Im sure theres something not qit right in samba.conf or is it something else.
I have one machine (out of a couple dozen) that continues to refuse to allow "vncserver :1" to start. It is perfectly happy with :2 - :9 but tells me :1 is already running - yet ps tells me that there is no running Xvnc instance. What have I done here and how do I get that session back? I've cleared the /tmp/.X11-unix entries but that did no good. Could I have checked something in Yast that is launching an invisible session?
i have a suse 11.3 machine and i cannot set it to be a NFS server that is i cannot mount a directory of this machine on another one running as well a 11.3 while i can mount without problem a directory from 10.0.i do not know where to start as the NFS server option seems to have vanished from YAST.
I have OpenSuse 11.3 with VirtualBox on it, and with installed Oracle DB (on host OS).. but, sometimes this computer is disconnected, without it's gateway (adsl router)... and in that case, I cannot ping from virtual OS to host OS, or another virtual OS. I tried to use 'Host only' option within VirtualBox, but it doesn't work. What should I do? It seems that virtual machines requires some kind of gateway/router, but since machine is disconnected, it's not working.. how could I fix it?
I may have to work in another state for some time, and I'd like to access my home machine desktop remotely, like this: Server - home machine, oS 11.4 64-bit, KDE 4.7, 1920 x 1200 screen (currently set to 24-bit color depth), 1 Mbps upload speed, behind a Dlink DL-524 router I manage.
Client: laptop, oS 11.4 64-bit, KDE 4.6.5, 1280 x 800 screen (also 24-bit color depth), unknown up/down speed - probably huge at work, crappy at apart hotel. I'd like to keep the server resolution, if possible, even if the client's is smaller. I want to be able to star/stop KDE apps in the server, move files between folders, and fix the issues that only happen when my wife is at the keyboard (it's a machine conspiracy, she says ). So I'd need to connect to the server's current session/user (which is myself, i.e., same login/password).
What do you recommend for this? I've read Swerdna's tutorial for 11.2/11.2 (a million seen malcomlewis xrdp 0.6 packages for 11.4 (you rock, malcomlewis!), as well as this thread: RDP into OpenSUSE 11.2, however most seem concerned with rdp between windows and linux boxes. Is there something better/faster/simpler for oS-to-oS RDP or should I use xrdp all the same?
I have a 11.1 NFS server and several 11.1 NFS clients. If for some reason the server shuts down before the clients then the clients become almost frozen, particularly KDE is rendered useless even after cycling back to init 3 then init 5. I would like to make the clients immune to shutdowns on the server.
Im trying to setup samba so that i can copy some files from my windows 7 machine over to the drive on the opensuse machine running 11.2. i believe i set everything how it should be set up but no matter what i do i cant write filesfrom the windows machine. Here is my smb.conf
# 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. # Date: 2009-10-27 [global]
Have a pureftp server on OpenSuse 11.2 (x86-64 bit), KDE 4.3.5, dual core AMD. It responds to ftp clients on another machine (openSuse 11.1) within the same subnet (192.168....) and delivers lists of directories, changes directories, etc. The clients (gftp, jftp, filezilla, dolphin--tried them all) are unable to upload to the server (after a successful log-in on the server as a user, not root) with an error message that seems to indicate an inability to open the file on the client machine. Also logged in as user on the client machine. From FileZilla:
Command:STOR FCtinyLogo2.jpg Response:553-Can't open that file: Permission denied Response:553 Rename/move failure: No such file or directory
What am I missing in permissions? The directory where the JPG is located belongs to the user who is signed in, its in his home directory. The users on the two machines are not the same.
I have the following problem with xterm on vnc on opensuse 11.4. I start a vncserver, and then inside that session I start xterm. However, if the xterm emits a beep/bel/ascii 7 then the sound comes out on the machine on which the *server* is running. Every other installation I've used has the sound come out on the viewer end (which is what you'd expect and want).
In short: browsing the internet with domain names does not work. The long version: I've configured my network with DHCP and ifup. Ping works on my internal net and with servers in the internet. Dig work's too! I get the right IP to the requested domain. When i try to access the internet using firefox or even wget i get an DNS error. For example wget is showing the following error: Resolving heise.de... failed: Name or service not known. wget: unable to resolve host address 'heise.de'
Again dig show me the right IP and if i add the entry to /etc/hosts it work's too! I've even tried it with manually setup of ip address, nameserver and default gateway but with the same result. Switching off the firewall has no effect on this problem, too.
I deleted the firewall files "K09SuSEfirewall2_init", "K01SuSEfirewall2_setup", "S11SuSEfirewall2_setup" and "S01SuSEfirewall2_init" from "/etc/rc.d/rc5.d" in order to disable the firewall when rebooting.
As a consequence all network services are not working. I can't connect to any other machine nor to the internet.
I rebuilt the symbolic files based on the ones for runlevel 3, but still no network services are available.
Any suggestions how to make it work again? I'm using Suse 11.3.
I install from openSUSE-11.3-NET-x86_64.iso. Installation was succesfull, but after install all packet on test internet / update was error. And after log in in installed system internet not work. I use router with DHCP
