Server :: Adding New VM - Failing Console Connection
Jun 21, 2010
I have a KVM server and am trying to add a new VM. The problem is I am unable to connect to the consle to finish the installation. I have put the details of the steps I took and my ssh config file for clarity. It seems I have a problem with a vnc 'security type'.
Code:
$ virt-manager -c qemu+ssh://root@phoenix:2200/system
[Prompt for password and connects OK]
KVM Server
Code:
# virt-install --connect qemu:///system -n web -r 1024 --vcpus=1 -f /dev/vms/web_os -s 5 -c ~ecosta/debian-504-amd64-netinst.iso --vnc --noautoconsole --os-type linux --os-variant debianLenny --accelerate --network network:default --hvm
Starting install...
Creating domain... 0 B 00:00
Domain installation still in progress. You can reconnect to the console to complete the installation process.

I can see the new VM but when I chose to open the console, the password is asked again and again without a successful connection to the console. The following is what I found in the log.
virt-manager log: .....
I then tried to make an ssh tunnel and use vncviewer to connect:
Code:
$ vncviewer localhost:2

i have successfully installed zimbra on Debian machine but am failing to log in to the console admin. i have used my server name as well as my ip address but both do not work.
I am trying to write a little port knocking daemon that needs to see every failed connection attempt on every port on the system. The primary way to do this (as the Wikipedia page points out) is to monitor the firewall log file. I am using UFW and reading its output in /var/log/kern.log. Typically, when UFW blocks something, it prints a little line like this:
But it seems that whenever UFW experiences a significant "load" (my client sends eight packets over the span of about 25 seconds, not too significant if you ask me), it just kind of "gives up" after 10 or so attempts. Log messages stop appearing in kern.log. I know the packets are coming; wireshark confirms this.
It seems to me that a buffer of some sort is filling up, because if I give the system a breather and try sending my sequence again in, say, three minutes, it prints log messages for 10-12 straight attempts before giving up again. I've tried sending packets at longer intervals and reading from other logs like /var/log/messages, but none of this has helped. Does anyone have any idea why UFW would fail to log all blocked connection attempts?
First i installed openwsman-server- .2.0-5.el5.i386. Then i installed sblim-sfcb-1.3.7 and sblim provider packages by building the source code. Then i gave cim-xml request directly to SFCB using "wbemcat" and i am able to enumerate classes and its instances. But when i try to give a request to SFCB through Openwsman using the following command "wsman enumerate http://sblim.sf.net/wbem/wscim/1/cim...ComputerSystem --port 5985 -y Basic -u <username> -p <password>" i get a response "wsa:EndpointUnavailable" and in Openwsman log it is displaying the following error message "*** Connection to CIMOM http://localhost:5988 failed with 1null)"
I checked the correctness of the CIM schema specified in the request and both sfcb's and openwsman's configuration files i didn't get any help.
I'm using Kubuntu 9.10, my pppd version is 2.4.5 and pptp is 1.7.2 I'm trying to connect to the iPredator VPN service, but I keep running into problems with LCP. I've tried using knetworkmanager, nm-applet, kvpnc and plain old text-based configuration to no avail. Here's a snippet of pppd's output:
[Code].....
(I've got "defaultroute" in my /etc/ppp/peers/ipred config file.) Any ideas what could be causing this? Could it even be my router? It claims to support PPTP, but considering it claims a lot of other things which aren't true, I wouldn't be surprised if it was the culprit.
My ubuntu system has been running really well until this morning - software update prompt appeared on the screen, so I ran with it and let it do its thing. A while after this, my WiFi network connection started failing. I've tried rebooting and then it can take up to five minutes or more for the password (keychain) prompt to appear. Once I have typed in the password the network connection starts to work. Then cuts out. Works. Then fails again.
Using Wicd and it keeps dropping out or telling me "bad password" when the password is in fact correct. I even know it works because the first couple of times it worked, but the connection wasn't sustained for more than a few seconds each time. My reasoning is my wireless is functional in Ubuntu, there's no reason it shouldn't be in Debian. Wireless network card is ASUS PCE-N13. Ralink driver is installed. WPA-supplicant is installed. Gnome Network Manager is also present, though I've heard that it doesn't support my particular situation.
I'm running an up-to-date Fedora 12 machine with the Gnome desktop (meaning with Network Manager). My network connection is a wired ethernet to a switch which then connects to a Netgear router. For some reason, this machine can't renew its leases with DHCP, so NetworkManager deactivates eth0, taking my machine off the network. I have to click Network Manager and enable eth0, which seems to work every time.
How can I fix it? Here are the relevant bits from /var/log/messages showing a failed DHCP request and then the successful renewal.
Code: Aug 1 04:00:08 ironton dhclient[12452]: DHCPREQUEST on eth0 to 192.168.1.1 port 67 Aug 1 04:00:08 ironton dhclient[12452]: DHCPNAK from 192.168.1.1 Aug 1 04:00:08 ironton NetworkManager[1261]: <info> (eth0): DHCPv4 state changed reboot -> expire Aug 1 04:00:08 ironton NetworkManager[1261]: <info> (eth0): device state change: 8 -> 9 (reason 6) Aug 1 04:00:08 ironton NetworkManager[1261]: <info> Marking connection 'System eth0' invalid because IP configuration expired.
I need to setup a Linux VPN server at work for resources' sharing, I currently have a server running CentOS 5.4, and tried endless tutorials on the web, but to no avail, and can't find where the logs are kept for the VPN server to check where the error is. But all my attempts to try to connect keep failing.
I am trying to get fedora-ds running on a machine. I can't log onto the console at all. If I use the command line below the log shows multiple instances on the following lines. fedora-idm-console -D 9 -x nologo
I have an application that uses a telnet console, and I have an autostart script to start it (and check that it is running).The problem is that if the program is not startet by root, or by using sudo, I cant get access to the telnet console, it just says "connection refused".The application works fine, but I cant acces its console, so I have to shut it down, and then restart it with sudo to be able to log in to it.Anyone know how to make the script start the application with enough rights?
I have set up a nis slave server on Fedora 14. It was set up on a laptop so that the user can log in when he is at home (no NFS, local home dir). However, whenever the eth0 is disconnected, ypbind fails.
I have tried the same setup on a RHEL 4 (configured it as a slave server) against the same master nis as on the Fedora 14. Disabling eth0 on it however does not fail ypbind.
Linux printing appeared to be working fine up until yesterday. Today typing lpq gives the following: lpq Printer 'sdst@other.domain' - cannot open connection - Connection timed out Make sure LPD server is running on the server
The /etc/cups/printers.conf file is properly set, the printers appear in localhost:631 and they are printing test pages. However, all command line print commands seem to be trying to print to sdst@other.domain I don't know why printers.conf is being ignored and why and how sdst@other.domain was added. Seems like it might have been auto-discovered?
# dit: sdst@other.domain was mentioned in /usr/local/etc/lpd.conf I'm not sure why lpd.conf is being used instead of /etc/cups/printers.conf
Is it possible to add the routes to my routing table for dynamic pppoe connections? I have this setup on windows 7 with power-shell scripting and some 3rd party commercial pppoe client called Cfos, but since I'm now trying to move away from windows to Ubuntu and cant use the same programs anymore and its getting abit tricky now. I'm not trying to do any fancy load balancing here just some basic stuff which should be possible. Here is same basic info.
My ISP resets my pppoe connection every 24 hours. However the advantage of this is that I can call out 2 or more simultaneous PPPOE connections through the same modem. This is my routing table I wrote which has 5 PPPOE connections [URl]..Id like this to be automated when the PPPoes reconnect and the computer restarts.
I two servers set up: 192.168.1.150 and 192.168.1.160 Initially, I want all traffic to be served by server 150. So for this purpose I am leaving the IPTables on .150 empty. At a point in time, I want to forward all incoming traffic to be served by .160 instead. I have accomplished this using these commands (on .150):
My problem is that if I have an open SSH connection to .150 (prior to adding the rules), the packets are still handled by .150 after adding the rules.. e.g. my SSH session stays active. I want these packets to be forwarded to .160, which would effectively disconnect the SSH session. I do not want the packets flat out dropped, I just want them forwarded on in whatever state they are in. If I try a new SSH session, it is properly forwarded to .160
I have created a VPN through network manager to a Windows 2003 server.
However when I try connecting it fails every time, I have tested with a windows XP client and this works so this would indicate I am doing something wrong in the network manager configuration.
I seem to be having a problem with mod_proxy and https websites. A simple connection to port 80 works fine but all calls to 443 fail.
I had a look at my firewall but can't see anything that would block port 443, although I get no tcpdump traffic on that port on the deb01 client when I try and connect to it. I disabled the firewall but still no luck.
My configuration consists of 3 VMs (KVM) each running a different website.
I get the following error when connecting to ssl deb01
Code: An error occurred during a connection to deb03.example.com.
SSL received a record that exceeded the maximum permissible length.
I have a Redhat fedora core release 6 (2.6.22.9-61.Ns4) server and form time to time ssh fails although I am still able to ping the device and with a reboot the device will start working correctly so upon further investigation it appears the sshd daemon fails.Not knowing a great deal about Linux I thought I would ask some advice on the path I am thinking of taking. The first would be to put an entry in the cron to try and start the ssdh every hour or so. Would this cause issues in the long term run it multiple times when the sshd daemon was still running?
The Second though I had was having a bash script to check if the process was running and if not restarts it and if it was just exit the program which would seem like a neater way to do it but this is where my limited Linux knowledge hits a wall so was looking for suggestion on how to implement this?
I'm a frequent user of the shared connection feature of SSH. Usually i have two or three connections open at the same time through the connection sharing feature, but sometimes when i try to start another i get the message "Shared connection to <server< closed". All the connection that are established through the connection sharing feature are still active and not closed, but when i try to create a new one i get that message.. i've even got that message when i have only had two connections through the shared connection feature.
I've tried to search google but it doesnt seem like anyone else has had the same kind of problem, does someone know why i sometimes get this error ?
For some reason my DNS servers aren't able to resolve certain names. Most names resolve fine there are just a few that don't work. Nslookup doesn't work either of course, and curiously neither does "whois".
I added the "@clustering" and "@kvm" keywords to my ks.cfg file but during installation, an error about not being able to find either of these packages popped up and it wasn't installed.
I do see the Cluster and VT directories in my redhat_es5.4 directory along with the Server directory. The rest of the files install just fine.
In doing some net and forum searching, I find a reference to a base.repo file that lists the directories but I'm not sure if it's related to creating a yum repository or if not, should it have been created in the redhat_es5.4 directory.
While I've built kickstarts for several years and am comfortable with the file, this is the first time I'm working with rpms outside the main Server path.
I just upgrade from 10.3 to 11.4. Everything went fairly smoothly and most things are still working execp nfsserver

we have a server that runs a backup (cron job) at 9:15 every night. When I log on in the morning I have mail message that gives me a long list of all the files that were backed up the night before. For a couple of weeks now, the mail message gives me an empty list. Yet, when I run the same job manually from a #prompt, it runs. I am not able to run this job with cron in the daytime because too many users are in it. I wanted to browse the tape to see if the backup is really failing to copy the files or if they are on the tape and the mail message is bogus.
Since the backkup was done with cpio instead of tar, I'm not sure if I can browse the tape with restore -i anyway.What would be the best way to browse the tape on /dev/rmt/1 without actually restoring anything ?This is an ancient DGUX system, not Linux, and I'm not a unix expert I just inherited this server recently, but a lot of things are very similar to Linux and it looked like this might be a good place to ask.
The title pretty much says it all. Once I get past GRUB, the font becomes HUGE and starts off screen. It appears to be center zoomed because I cannot see the login prompt nor anything I type. It's not really an emergency, I installed OpenSSH during the OS installation and can just turn it on and log in over SSH or start up Webmin. It just bugs me that I cannot figure this out.
There is no graphical environment installed, so it's not a video card issue. I tried adding vga=ask as a kernel flag and then tried several options, but to no avail.
I'm a light linux user over the last couple of years and I decided to built a HTPC/NAS device.
Setup: 40gb ide -> usb boot drive 3x2tb sata (4k Sector) drives
I've got another 2tb identical drive but it's holding data that is going to be copied to the raid after it's up and running and then be 'grown' into the raid array to yield a final 5+tb array. I tried doing a disk util raid array and it ended up failing after reboot due to it using the /dev/sd* designations and they swapped. I have no idea how to do the UUID version, my googlefu and practical guide to ubuntu. So I decided to do it manually in order to also fix the sector issue as disk util wasn't formatting them correctly and once formatted wouldn't let me create a raid array from the discs.
I seem to have a complex issue on my hands that i can't figure out. first, i wasn't able to get access to my LVM'd hard drives via SSH without half of the content being missing or locked out (read-only or unable to open at all). the problem then went up to being unable to boot up - all i got was a long slew of [100.1234] ata1.00: error messages (they eventually DO stop once they get to around 998.234234 or whatever, and then i can log in and it seems to be "stable").
Part way through this rebooting ordeal i realized / decided to make power-on-self-test stop and wait if it finds errors (via bios) - that showed me that my 750G SATA drive is "bad" and my two (older) 120G & 250G IDE drives are "ok". i then unplugged the SATA drive, rebooted, and didn't see those error messages. however, my LVM was still obviously not coming together (since LVM was made up of the 120G, 250G, and 750G drives)
So, now it seems:
a) I can't boot smoothly with all drives in place b) I can't do anything with lvm if i remove the 750G sata c) With all drives hooked up, i can wait 10mins for the errors to go away, but STILL can't do anything with lvm d) I need to recover the lvm stuff so that i can nicely migrate ALL those files (1.1TB of it) onto a new 1.5TB drive and do away with lvm
This is all running ubuntu 7.10 server edition (32-bit version on a 64-bit computer). i DID post a question on the ubuntu forum as well but so far got no replies at all.
Here's a few pics of the booting process, with one or two "fail" lines showing.
I am trying to connect the one of server RHEL5.4 to the IBM iSCSI storage. Server is equipped with 2 single port Qlogic iSCSI HBA(TOE). RHEL detected the HBA and installed driver itself (qla3XXX). I have configured the HBA ip address in the range of iSCSI host port of storage. Both of the HBA is connecting to the two different controller of storage. I have discovered the storage using command iscsiadm -m discovery command for both of the controller and it went through fine. But problem is whenever server is restarting if both of the hba is connected to the storage then server will not detect the volumes which is mapped to the server and then to detect the volume I need to run "mppBusRescan" and "vgscan" command each time. If only one path is connected it is fine.
I am Amit, working with IGate. I am able to configure NIS server and client,but after configuring server and client,when I add a new user to server and client and when I login througy new user from client, It shows error "user cannot found".I added a new user to NIS server make entry of user to client pc in /etc/auto.master file and restarted the services bind,nfs,autofs,portmap on server also restarted the serveces on client bind,autofs,portmap then alon I cannot login by new user on client matchine. Please tell me what is cause and how to resolve it.I shared server's /home dir and on client pc automounted the server's /home dir by making entries in /etc/auto.misc file on client pc.
