• Trouble installing Server 12.10 - Dead keyboard, Blank Screen, Network Config

  - by Mikey

  Installing 12.10 server from cd - minimal installation: basic system, ssh server,postgreSQL, manual updates. Hardware is brand new HP server that also runs Win 2003 Server Standard as a DNC excellently - I installed the grub boot manager on the primary partition and it is working fine - can boot to Win or Ubuntu without issue. Everything seemed to go OK on the installation - BUT when I restarted the system after install and booted to Ubuntu, I got the command prompt for Ubuntu, but the keyboard was UNREPSONSIVE - dead. There is nothing wrong with the keyboard - works fine if I boot to Win. With a completely unrepsonsive keyboard I had to hit the power switch - when I restarted and booted to Ubuntu, Ubuntu started but no command prompt came up at all - just black screen. I powered down and rebooted to advanced Ubuntu options - it tried to reinstall/initliaze a long list of packages - when it got to 'waiting for network configuration' it waited, then a message 'waiting 60 seconds for network configuration'... it waited 60 seconds and then I got a 'failed to configure network message' and it continued. Finally it finished, I hit enter and got to a prompt - but again, keyboard UNREPSONSIVE - dead. I went through this several times - tried 'repairing broken installation' option and also reinstalling entirely - always same results. I am flummoxed. The only clue I have is that for the Windows DNC config, the IP address is static - not via DHCP. But I don't think that should impact Ubuntu at all - perhaps I am mistaken. What is wrong?

• Dual LAN Printing

  - by Christopher

  I want to use Ubuntu 10.10 Server in a classroom, a computer lab whose bandwidth is provided by a local cable ISP. That's no problem, though the school network has an IP printer that I want to use. I cannot reach the printer through the cable Internet. But, I have two network cards. How is it possible to use both networks at once? eth0 (static 192.168.1.254) is plugged into a four-port router, 192.168.1.1. On the public side of the four-port router is Internet provided by the cable company. I also have the classroom workstations plugged into a switch. The switch is plugged into the four-port router. The whole classroom is wired into the cable Internet. The other NIC, eth1, could it be plugged into an Ethernet jack in the wall? It uses the school network, and I might receive by DHCP an IP address like 10.140.10.100, with the printer on maybe 10.120.50.10. I was thinking about installing the printer on the server so that it could be shared with the workstations. But how does this work? Can I just plug eth1 into the school network and access both LANs? Thanks for any insight, Chris

• How to disable "N" Wireless Mode RTL8192 (Thinkpad Edge 15 Core i5) in natty

  - by Gustavo Rubio

  I've seen many owners of thinkpad edges which are supossed to be linux-friendly having problems with wireless adapter. I've found several links inside askubuntu and in ubuntuforums which have a lot of work-arounds for those problems, mine seems to be wierd though. I use my laptop on both my office and at home. At home I have a router which is A/B/G and here at home the wireless connection works just fine, using a WEP key. But in work I have a B/G/N wireless router and it doesn't work, my guess is that this adapter works with N modes but somehow this is buggy in the bundled driver in natty. I've tried to disable the "N" mode in the router but that didn't work. Later I went to realtek website, downloaded their driver and compiled myself, kinda seems to work most of the time but sometimes some websites keep trying to load or load just parts of it and images start to look like their links are broken and so on, much like what you get when you were loading a page and suddenly the connection is lost. This problem, as I said, is only using the realtek driver from their website. Dmesg gives me this a lot of these: [ 5869.049454] rtl8192se_update_ratr_table: ratr_index=0 ratr_table=0x00000ff5 [ 5879.240563] DHCP pkt src port:68, dest port:67!! So I thougth I might as well switch back to the original driver which seems to work just fine on A/B/G wireless networks but not on N networks so if anybody knows how to disable that mode from within the driver please let us know :) Thanks in advance! PS: I do found a link to a similar question and it was answered but let me remind you I'm NOT using the intel version of wireless for my thinkpad but the realtek (RTL8192SvB)

• J2EE or .Net Framework [closed]

  - by Kevino

  I want to learn JAVA or C#... tell me the strength and weakness of each platforms J2EE and .Net Framework today in 2012 and which is safer for the future jobs wise? I tend to prefer Java because here (Montreal, Toronto) there is like 6 Java jobs for each C# jobs and some experienced programmers advised me to go with Java because they say JVM languages are winning in the cloud and the rise of Android can't do anything except help Java in the long run. Is that true today with the release of windows 8 soon and ios devices? On the other side 1 of these programmers told me that corporation love Asp.Net Mvc3 for intranet and web dev and that tomcat/apache java jsp adoption is slowing down compared to Asp.net and ruby on rails & html5 etc. He told me too since I have a good background in system admins & networking C# would be better for me because I'll be able to do more things in the microsoft world with powershell automation and creating my own apps for all the networking stuffs (windows server, dns,dhcp, active directory, sharepoint etc). But what if windows 8 flop java and android aren't safer in the long run? because he told me mono was a joke compared to Java/android or native objective-c on ios devices. (I plan to do a full time study of 10hr's / 15hr's a day for the next 9 months of either Java or C# that's why I ask this)

• Kubuntu 12.04 - DNS Issues

  - by AndrewJesaitis

  Starting yesterday (6/11/12), I've been having many network problems. When requesting a page in chrome, the page hangs on "Sending request" and then will eventually timeout. I'm within a VPN that has it's own DNS server. I've tried to manually set my DNS through the Network-Manager applet and by editing /etc/network/interfaces. Having no luck I unlinked the resolv.conf file and dumped the contents of my old resolv.conf into it. Again having no luck, I deactivated the dnsmasq server in /etc/NetworkManager/NetworkManager.conf by commenting out the dns=dnsmasq. $ cat NetworkManager.conf [main] plugins=ifupdown,keyfile #dns=dnsmasq no-auto-default=D0:67:E5:EA:B6:6B, [ifupdown] managed=false $ nm-tool NetworkManager Tool State: connected (global) - Device: eth0 [Wired connection 1] ------------------------------------------- Type: Wired Driver: tg3 State: connected Default: yes HW Address: D0:67:E5:EA:B6:6B Capabilities: Carrier Detect: yes Speed: 1000 Mb/s Wired Properties Carrier: on IPv4 Settings: Address: 192.168.254.122 Prefix: 24 (255.255.255.0) Gateway: 192.168.254.2 DNS: 192.168.254.1 What is strange is that the network will work fine for a few minutes then start to timeout. A few minutes later it will work again. I'm unable to hit internal or external sites when it is timing out. When I $dig local sites, I receive no answer. I do receive an answer from google.com. At this point, I would usually blame the DNS Server, especially since when I change to Google's DNS server things work. But, I need to use our internal DNS to hit our internal sites. Nobody else is having issues and they are all using DHCP. This group includes one user who is using 11.04. At this point, I'm at a loss for what to do, so any help would be appreciated.

• Install VirtualBox Guest Additions "Feisty Fawn"

  - by codebone

  I am trying to install the virtualbox guest additions into a feisty fawn (7.04) VM. The problem I am running into is that when I Click install guest additions, or place the iso in the drive manually, the disk never shows up in the machine. I even manually mounted and went to the mounted directory and it was empty. When using the file browser, doubling clicking on the cdrom yields Unable to mount the selected volume. mount: special device /dev/hdc does not exist. Secondly, I tried installing via repository... but according to the system, I have no internet connection. But, I can browse the web using firefox just fine (in the guest). Here is my /etc/network/interfaces file... code auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp I also tryed setting a static ip... auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.253 netmask 255.255.255.0 gateway 192.168.1.1 The reason I am trying to get this particular installation running is because it is part of a book, "Hacking: The Art of Exploitation" (Jon Erickson), and is fully loaded wilh tools and such to go along exactly with the book. I appreciate any effort into finding a solution for this! Thanks

• How to connect Ethernet on Ubuntu (with auto-detection)

  - by user12285

  It's been well over six months but I have the same router SmartAX MT880d with Ethernet, and the exact same problem : no internet, even though I can successfully reach the modem settings page by entering 192.168.1.1 in Firefox. I'm a total beginner with Ubuntu. My internet works great in Windows but does not work in Ubuntu. Sorry if I don't use the right (technical) terminology to explain my issue. English is not my mother tongue. For 2 weeks, I've been doing reading on the web and forums and the ubuntuguide.org to name a few, but to no avail. Now I see no other solution but to ask for help. My problem is that I can't find a way to put the right digits in the right place because I don't know what numbers I need to put in what files. E.g.: do I need to use DHCP? or a static IP address? No clue whatsoever. I'm concerned that I might put figures in the wrong spaces. For example, is the modem/router's IP exactly 192.168.1.1 for Huawei Smart AXMT880d modem? Is the subnet 255.255.255.0? Gateway 192.168.1.1? I'm confused as I can also see a different IP starting with 155131*** (is it an account number?) on my contract with Huawei (a Chinese ISP). Apart from calling 911, what other numbers do I need to put in and where? How do I check that all the numbers have been entered correctly in every appropriate space before trying to connect the Internet?

• Cannot ping any computers on LAN

  - by Timothy

  I havem't been able to find a straight forward answer on this yet. I'm hoping people here are able to help! Keep in mind that I'm a complete beginner at this - this is the first installation i've done for any LINUX systems ever so please keep that in mind when answering this question. We are a complete Windows shop, using nothing but Microsoft products but looking into the value of OpenStalk however have been having problems getting Ubuntu Server installed and speaking to the network. The machine is getting an IP address which is telling me that some sort of DHCP activity is working but I'm not able to ping any computer on our network as well as not able to connect to the internet. Every time I try to ping i'm getting; Destination Host Unreachable I've tried using modifying the resolv.conf file with our static details to match my Windows 7 machine still with no luck. Even tried disabling the firewall on Ubuntu Server 11 and no luck. Any ideas? Please let me know if there is any information you need from the server and I'll post up.

• Reverse WiFi to Broadcast connection coming from a USB device

  - by Daniel Clem

  I am using the app called Clockworkmod Tether. It connects using a script ( command line " gksu ./run.sh " ) on the computer. All my programs connect to the internet perfectly, minitube, midori, transmission torrents. But the network manager does not show any connection, wired or wireless. So this may cause issues? What I want to do is take this connection, and be able to share it some way, any way, by wireless. This Acer Timeline "Aspire 5810TZ" does have an Ethernet, so wired out to a router might be an option. But I would prefer to simply reverse the Wireless card to broadcast out to about 2 or 3 devices. Is this possible? Yes I have taken a look at the other questions already posted here, but the answers are 1 year old or older, and not clear at all. I am moderately comfortable (4.5 out of 10 ) on the command line. But pretty much need line by line directions for what commands are needed and what order, ect. Edit I have already tried the method of "Left click network manager, Create New Wireless Network" It is created fine, and I am able to connect to it with a tablet, but am un-able to get an outside connection with it. Using the "Shared to other computers" option because DHCP doesn't seem to work, and WEP Passphrase Security. I get an IP address on the connected device. But as I said, won't bring up any outside webpages or the like. So perhaps this is the wrong approach?

• Reaping the Benefits of the Image Packaging System

  - by rickramsey

  source One of the promises made about Oracle Solaris 11 was easier installation. Remember? Do you also remember how involved installing Oracle Solaris Cluster used to be? It was so involved, in fact, that we (when we were Sun Microsystems) wouldn't even let you do it yourself. How times have changed. New - How to Automate The Installation of Oracle Solaris Cluster 4.0 Thanks to the new image packaging architecture in Oracle Solaris 11, you can now automate the installation of Oracle Solaris Cluster 4.0. Why is that such a big deal? As Lucia Lai explains it: "Without the AI, you would have to manually install the cluster components on the cluster nodes, and then run the scinstall tool to add the nodes to the cluster. If, instead, you use the AI, both the Oracle Solaris 11 and the Oracle Solaris Cluster 4.0 packages are installed onto the cluster nodes directly from Image Packaging System (IPS) repositories, and the nodes are booted into a new cluster with minimum user intervention." Lucia goes on to explain how to set up and configure the AI server, how to plan your cluster configuration for the automated installation, how to use the scinstall utility, how to set up the DHCP server, and more. A thorough, well-written article. - Rick Website Newsletter Facebook Twitter

• Adventures in Lab Management Configuration: Part 3 of 3

  - by Enrique Lima

  This is long overdue.  But here it is. In the previous two sections I have discussed on how I got a CMMI v4.2 to take on the same fields as v5 and therefore be able to communicate with MTM and Lab Manager.  And that was quite a success. Yet when I opened up Lab Management while it was fully aware of the VMs being there, it refused to let me enroll them into an environment.  It kept stating there was no suitable host to deploy the VM to, error TF259115. This was an indication something was not matching the expected network configuration between TFS and Hyper-V/SCVMM. So, here are a couple of things that took place: Verified the network segment specified for network isolation matched what was configured physically for either DHCP or manually assigned IP addressing for the guest VMs Made sure TFS was fully aware of the configuration settings for the network location name.  For that I issued:  tfsconfig lab /settings /networklocation:”<name of the network location configured in SCVMM” On that last item, that was key to making sure Lab Management communicated with the VMs and for it to allow enrollment into the new Virtual Environment.

• My internet connection slows or dies unexpectedly

  - by genesis

  I installed Ubuntu 10.04 once again and I'm having some problems which I had before, but I have no idea how I solved them. On Windows, everything's working fine and I had no problems with this. My problem is that sometimes, when browsing through the internet, webpages just start to load really slow, sometimes it doesn't load anything at all (Error 118 (net::ERR_CONNECTION_TIMED_OUT): The operation timed out.) and it starts to work after few minutes. My IPv4 settings are automatic (DHCP), and IPv6 settings are Ignored/Disabled. I think my previous problems had something to do with IPv6, but I'm not sure. Is there a fix for this? iwconfig lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"Fsite1" Mode:Managed Frequency:2.442 GHz Access Point: C8:3A:35:40:43:68 Bit Rate=0 kb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:on Link Quality=43/70 Signal level=-67 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0

• Set up a GUI managed firewall for other machines?

  - by Azendale

  What ways are there of setting up a firewall for traffic routed for other machines whose rules can be managed by a GUI? Can GUFW do it? FireStarter? (or should that be avoided because it is supposedly no longer updated?) *By filtering, I'm mean the traffic I am setting rules up for is not destined for this computer. It is either from or to other computers on my LAN. Say, for (a simplified, hypothetical) example: I have an ethernet connection at my dorm that I have plugged into eth0. It gets an address of 192.168.1.185 and I also have 192.168.185.0/24 routed to me, so I don't have to do any NAT. I have a hub attached to my second ethernet port (eth1) with a few Windows computers and I give addresses out of my 192.168.185.0/24 block with DHCP. How can I use my Ubuntu box to block incoming connections from eth0 that are being routed to my Windows computers and let through just a few specific ports (so fellow students can't see what files my Windows boxes are sharing via SMB)?

• Ethernet Connection Unavailable

  - by fabikw

  I'm running Ubuntu Server 12.04 on a laptop with an Intel NIC (driver e1000e). When I connect the ethernet port to the internet (college network, DHCP) it works out of the box. Now I'm trying to connect it to a networked USRP (if you want to know what it is). A friend of mine managed to do this in his laptop (running regular Ubuntu 12.04) just by setting up a new Wired connection in the Network Manager with appropriate addresses. However, when I do the same, no wired connections are available. The output of nmcli -p dev is =========================================== Status of devices =========================================== DEVICE TYPE STATE ------------------------------------------- wlan0 802-11-wireless connected eth0 802-3-ethernet unavailable but the cable is connected to the device and the device is powered up. Any idea how to solve this? UPDATE: After stopping the network-manager service, setting up the connection manually and starting the service again, it now detects the ethernet connection. However, the device still can't receive data and doesn't answer to pings. UPDATE 2: As suggested I tried using a cross over cable but the result is exactly the same. However, I found out that connecting the device to the dock (as opposed to directly to the laptop) works fine. I know that the ethernet port in the laptop works fine, because connecting to the network through it works. Is it possible that the port in the laptop doesn't support Gb Ethernet (because that's what the device requires) but the one in the dock does?

• unreachable subnet in one direction

  - by Carl Michaud

  I'm unable to route traffic to a subnet in my home. Here's my topology: INET <- Router A <- Router B <- WIFI AP where: Router A - ARRIS TG862G/CT (from comcast) - WAN DHCP, LAN 10.0.0.99 Router B - Linksys WRT400N with DD-WRT - WAN 10.0.0.12 , LAN 10.0.1.1 I was able to use DD-WRT to configure a static route for the 10.0.1.x network back to the 10.0.0.x network. But I'm not sure if i can do the reverse on the ARRIS router and was looking for suggestions on how to fix that. I've set things up this wasy because I am using OpenDNS to mange internet content for my kids and of course I wasn't able to configure DNS to my liking on Router A either. So at present I'm using Router A on 10.0.0.x to provide a private unfiltered WIFI AP (no ssid broadcast) that I use for netflix only and then I use router B to provide a filtered WIFI AP for the rest of my WIFI devices on 10.0.1.x. However I would like to be able to connect to my 10.0.1.x devices from the internet via dynamic dns; but I can't see anything behind router B this way. Thoughts?

• Virtualization in Ubuntu 11.10

  - by Mascarpone

  Since Ubuntu 11.10 use a new kernel, it's very difficult to have a decent support for virtualization. VirtualBox doesn't support guest additions for ubuntu 11.10, so I can't copy to and from my ubuntu desktop and windows, which I absolutely require, plus FreeBSD seems not to be able to use DHCP without guest additions. Virt-manager instead gives an error on launch: Unable to open a connection to the libvirt management daemon. Libvirt URI is: qemu:///system Verify that: - The 'libvirt-bin' package is installed - The 'libvirtd' daemon has been started - You are member of the 'libvirtd' group unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: Permission denied Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/connection.py", line 1146, in _open_thread self.vmm = self._try_open() File "/usr/share/virt-manager/virtManager/connection.py", line 1130, in _try_open flags) File "/usr/lib/python2.7/dist-packages/libvirt.py", line 102, in openAuth if ret is None:raise libvirtError('virConnectOpenAuth() failed') libvirtError: unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: Permission denied The problem is solved by running virt-manager as root, but I don't like that. How do I change permissions to run Virt-Manager as user? Is there a way to install guest additions on Ubuntu 11.10?

• Can't connect to Wireless Network - Ubuntu 12.04 LTS & Sabrent A111N USB Dongle

  - by Ohgodwhy

  I've been trying to connect to this network for quite some time. I can't directly connect to the router with a Wire, but can access the Router with other wireless devices without any issues. I had previously tried several other Wifi nic's but none of them would load properly. Today, i went and bought a new (supported) Sabrent A111N USB Dongle, which said explicitly that it works with Linux 2.4 +. I popped the Dongle in, and low-and-behold it immediately said that there were Available Wireless Connections. I selected my connection and tried to connect, but it just loops constantly while saying Wireless Disconnected then attempts to connect again over and over. ifconfig and iwconfig both show my device in a ready and working state. However, iwlist wlan0 scan says that there are no results found. I don't get it... At one point, I could see the CPU in the DHCP client list under the router, but it doesn't fully make the connection (something about a timeout?). Any help would be appreciated.

• Ubuntu 12.04 Network Manager: unable to save manual setting to set up a static ip

  - by Andy

  I am fairly familiar with setting up servers, and ubuntu is generally my flavor of choice, but I just installed 12.04 desktop and I am seeing some behavior in network manager that is really puzzling. The network connection works fine if I leave it set on dhcp, but I would like a static IP address for my new web server. When I go into network manager and edit the connection for the one and only NIC I can select MANUAL from the dropdown menu but as soon as I do the Save button becomes greyed out. Even after filling out all fields for the connection it is still grey and I am unable to save the static IP connection information. Any thoughts would be greatly appreciated. I'm hoping there is just some new setting that I am unaware of.... On another note, if I stop the network manager and go edit the interfaces file (and the appropriate hosts/routes/dns files), I do get a static ip address assigned and I can contact my server from the outside, however, the server cannot find the internet. Can't ping even its own ip... I can ping the loopback interface though. I'm really confused on this one. Hoping someone can offer some help.

  Do I need to post another thread for the same? If so, sorry.

My internet works great in Windows but does not work in Ubuntu. For 2 weeks, I've kept reading on the web and forums and the ubuntuguide.org to name a few but to no avail. Now I see no other solution but to ask for help. My problem is that as a beginner, I can't find a way to put the right digits in the right place because I don't know what numbers I need to put in what files (eg: do I need to use DHCP? or a static IP address? No clue whatsoever. I'm confused between putting figures in the wrong spaces. For example, is the modem/router's IP exactly 192.168.1.1 for Huawei Smart AXMT880d modem?? Is the subnet 255.255.255.0? Gateway 192.168.1.1. I'm confused as I can also see a different IP starting with 155131*** (is it an account number? no clue again) on my contract with Huawei (a Chinese ISP). Apart from calling 911, what other numbers do I need to put in and where? How do I check that all the numbers have been entered correctly in every appropriate space before trying to connect the Internet?

• How to host an AP or a hotspot?

  - by user1048138

  I'm running Ubuntu 12.04 as a virtual machine on my Mac. Since I am unable to get the virtual machine to have full access to my WiFi card, I bought another USB WiFi card to use. This is my WiFi card. If you are unfamiliar with Virtual machine, as far as I know, since the Ubuntu has its own card now, it shouldn't matter. I have followed these guides with no luck: https://help.ubuntu.com/community/WifiDocs/WirelessAccessPoint http://www.danbishop.org/2011/12/11/using-hostapd-to-add-wireless-access-point-capabilities-to-an-ubuntu-server/ The problem is that the WiFi connection appears on all of the machines that I have in my house: 2 iPhones, Dell machine running Ubuntu and two Macbooks. However the connection times out on all of these machines. Questions: Could this be a driver issue if that same WiFi card can connect to other WiFi points and use its internet Could this be DHCP related? I would think not. It should at least get a 169.X.X.X address? No? Any solutions for me?

  I have a Hewlett Packard DV6. I connected to the access point. I receive an IP address/default gateway/DNS,etc(DHCP). I cannot ping my gateway. DNS lookups fails. There is just no connectivity. My driver is listed as being IWLWIFI. An lspci shows my card to be a Realtek RTL8101E/RTL8102E. I can't ping myself from another computer. eth0 Link encap:Ethernet HWaddr c8:0a:a9:0c:a7:45 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:41 Base address:0xe000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:561 errors:0 dropped:0 overruns:0 frame:0 TX packets:561 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:42164 (42.1 KB) TX bytes:42164 (42.1 KB) wlan0 Link encap:Ethernet HWaddr 00:26:c7:04:97:c0 inet addr:192.168.1.109 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::226:c7ff:fe04:97c0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:12 errors:0 dropped:0 overruns:0 frame:0 TX packets:71 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2035 (2.0 KB) TX bytes:12371 (12.3 KB)

• How to start Ubuntu with no working video card?

  - by ViliusK

  I have a laptop with broken video card. It has two operating systems installed - Windows 7 and Ubuntu 10.10 Desktop Edition. It has GRUB to manage which operating system to boot up. Windows is default OS. And Windows fails to boot up without video card. I'm checking with ping to the ports which are shown as used by DHCP in my router. Normal boot of Ubuntu also fails and it restarts after a while. But when I choose (blindly, but checking HDD indicator and by counting button presses when GRUB menu appears) to boot second option of Ubuntu (rescue mode) it starts and I can ping it. But when I try to connect to it through SSH, I'm getting "connection refused" error from putty. I've took out HDD from my laptop already and inserted it to WD Passport case so now I can connect it to other computer to edit configuration files. How can I check if SSH server is working? How to enable it in rescue mode? Or better, how to disable video card to be required while booting Ubuntu in normal mode?
