Debian Configuration :: Ssh Doesn't Work After Sending Reboot Command
May 2, 2011
last week while I was using ssh to the computer1 inside a NAT as usual, I made another tunnel from the computer1 that I was connecting to, to another computer2 inside that NAT (ssh 192.168.1.130) and after making some changes in computer2 I typed reboot. The computer2 rebooted but the tunnel totally hung and I had to kill it in my laptop. Since that day I haven't been able to ssh to the computer1 as I am used to.
Here is some more information:
debug3: authmethod_is_enabled publickey
debug1: Next authentication method: publickey
debug1: Offering public key: /home/une/.ssh/id_rsa
I have installed Firestarter, and set it up following some manual (just a simple, baseline setting, nothing fancy). However, after restart I got error message: Starting the Firestarter firewall... failed! and then, later: startpar: service(s) returned failure: firestarter ... failed! Why this happens?
I've upgraded a server on our LAN from fully functioning Wheezy to Jessie. All seems fine except remote administering using Putty from my windows workstation when issuing reboot from command line, it goes down and reboots but stops at login prompt asking for username and password and does not come back on the LAN network. This server does not normally have a monitor or keyboard so my ability to remote admin this server in effect is disabled.
If I log on, it will come back on the LAN network. I've checked the logs but can't see any errors. Is it in the configuration of Jessie somewhere or perhaps a Grub issue. I have 5 other production Wheezy servers that I intend to update to Jessie once I understand how to deal with this problem.
I have an Atheros wireless USB dongle that will connect to my Wifi network just fine in Gnome but in KDE doesn't. I've read through the http://wiki.debian.org/WiFi/HowToUse and have installed all packages and tried all methods noted there but still can't get the wlan0 to work at all in KDE. Is wireless in KDE & Debian Squeeze useless?
So, as per Arch Linux's wiki, I tried to make some optimisations to the intel driver through setting it up in Xorg.conf (or as advised by that wiki article, in '/etc/X11/xorg.conf.d/20-intel.conf' ), but I've ran into trouble enabling DRI3. Here's my current config file:
So far everything works fine, I haven't seen any noticeable tearing, nor did I had any problems with any graphics-intensive programs I run, but there's a slight problem with the DRI3 part as indicated by Xorg's logs:
Code: Select all[ 26.556] (II) Loading sub module "dri2" [ 26.556] (II) LoadModule: "dri2" [ 26.556] (II) Module "dri2" already built-in [ 26.556] (==) Depth 24 pixmap format is 32 bpp [ 26.616] (II) intel(0): SNA initialized with Haswell (gen7.5, gt2) backend [ 26.616] (==) intel(0): Backing store enabled
First of all it still mentions the DRI2 driver, is this supposed to happen, or did something go wrong? Also it complains that it cannot find a file, which I can't figure out which package it belongs to, and taking a quick search around the interwebs hasn't produced anything useful...
The IGP is the CPU, which is actually a i5-4460... which according to Wikipedia it has a HD Graphics 4600 GPU.
My net-book is working properly with Debian squeeze 2-6-32-5-686, only the wlan does not work. After typing lsusb I have got the message: lsusb : Bus 002 Device 002 : ID 160a:3184 VIA Technologies, Inc. VIA VNT-6656 [WiFi 802.11b/g USB Dongle]
So I obtained the driver package : VT6656_Linux_src_v1.19_12_x86. I followed the instructions ( make install... ) - but the result is only a lot of error messages. Mayby I am using the wrong driver package for the squeeze kernel - I don't know.
i created a second instance of postfix.It isn' t the first time that i made this procedure but with debian i had a lot of problem.I think that the problem is chroot configuration of postfix .In the first i had two problem smtp “fatal: unknown service: smtp/tcp” and the second instance was enable to make nslookup of domain.I copied the necessary file in /var/spool/postfix-second-instace and i solved the errors.Now the problem is that there aren't error in log file but connect to xxx.xxx.net[yyy.nn.yyy.yyy]:25: Connection timed out for all connection. and the email are all in defer directory and the second instance doesn' t send emails.
Debian configurating, so I try to use wifi adapter, but it doesn't work. I have installed Debian Jessie from netinst CD. To reach perfect speed no options were selected. After I installed xfce4 and xfce4-goodies.I follow some different instructions and no dice. Wicd show me no avalable wifi connections. used Ubuntu 14, Ubuntu 12, etc. and I didn't have any problems with wi-fi connections. Some outputs of comands...
I have Debian Squeeze x64 on ThinkPad T61p with standard 2.6.32-5-amd64 kernel. thinkpad_acpi loaded as module, suspend to RAM works fine from menu in KDE as well as by closing the lid, however machine doesn't appear to react on pressing Fn+F4 which should put it to sleep as well. I've read through thinkpad_acpi documentation and asked Google but so far can't find the solution. Can anyone, point me in correct direction?
I have recently bought a branded Onda MT835UP USB broadband modem. The hardware comes with its own drivers/GUI for linux, however I'd rather use the Debian-provided NetworkManager+modemmanager packages.
A few details:
- I'm using debian unstable, - latest NetworkManager 0.8.2-3 from experimental - latest modemmanager 0.4+git$foo from testing - latest usb_modeswitch[_data] from experimental
I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.
My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.
I saw that Evolution 3.0 was available for 11.04 so I decided to give it a shot. I installed it via ppa following these directions:
There were a bunch of dependencies that installed and required a restart. Upon reboot, autologin doesn't work and graphically the desktop is uglier with a different theme. Unity is not working properly, the wallpaper does not exist and many, many artefacts are present.
Based on my description and the posted instructions, is there a way to undo what I did short of a format and re-install?
I read about PulseAudio and thought it might be nice to try (especially the way you could individually control the volume of all applications seems nice), so I installed it and it worked fine.
I rebooted, and now it doesn't work again. Before, when I opened pavucontrol and went to the "Output Devices" tab, it showed the actual output sevices I have. Now it only lists one called "dummy output".
So what's the problem? Also, can I start it before X11 (I guess that putting "pulseaudio --start" in ~/.bash_profile should do it)?
reason my Debian 5 system will not stop printing blank pages. I've got the CUPS system installed, and I've gone to the control page and canceled everything. I've also turned the printer off and restarted it several times. Every time it comes back online it starts printing blank pages again. My paper does not need to be heat treated. It's fine as it is. So, how to I stop this waste of electricity and printer MTBF? What else might be sending commands to the printer besides the CUPS system?
I have installed Fedora 12 on my laptop.Installing my Broadcom BCM 4312 wireless drivers works just fine, but after a reboot I have to reinstall them. modprobe wl, modprobe wlan0 etc doesn't work either. I need to reinstall them every time I reboot.
I have a Microsoft LifeCam webcam. It works great under Ubuntu 10.04... Until I reboot. After the reboot, Cheese reports no device connected. I have to get down behind my PC, unplug the webcam and plug it in againThen it works... until the next reboot.
Since we switched our server to Squeeze, I'm receiving emails from the cron about a mysql error (...can't use locks with log tables). But this is not the issue I want to talk about here. The issue is that since the executed command is: /usr/bin/mysqlcheck -uroot -pmypassword --all-databases --check-only-changed --silent which is a command that was automatically added to the cron by the mysql package (I believe), the password is sent in clear text in the email's subject. In my sense, this is a serious security issue (sending root password in email subject...)
I don't know at what level it should be corrected, but it seems to me like it should be corrected in the Debian distrib, shouldn't it ?
And for now, how can I hide the password in the emails I receive ?
Struggled a little to get Broadcom driver working with my Dell laptop. But I am at a point where if I manually type 'modprobe b43' the wireless works. If I reboot, it doesn't work automatically and I have to 'modprobe b43' again. Any ideas what I am missing here?I can't seem to figure out how to get this to work automatically. I did check to activate device when computer starts in network manager
I have installed knoppix 6.0.1 persistent to a usb flash drive. I am currently testing it on my laptop and have successfully installed the graphics driver for nVidia Geforce 7150m driver 180.51 All looks great until i restart and it doesnt work again. when i go to reinstall it, it says its already there, but when i open the nvidia-settings, it doesnt look the same as before. If i reinstall it, it works again, until i restart of course.In case this is important, here is how i installed the driver in root terminal: sudo apt-get install gcc make init 3 cd /home/knoppix/Desktop sh NVIDIA-Linux-x86-180.51-pkg1.run (A series of questions come up asking to compile a kernel, etc.) (install runs) init 5
I am guessing that the new kernel needed for the driver that is installed is not being booted up on when knoppix restarts. I am just unsure as how I can make this kernel accessible at start up or how to start up this kernel again without reinstalling the driver
i have a HP MSA 2312fc SAN with 2 LUNs configured. The first LUN (LUN ID 1) is correctly connected to the system, but when i connect the second LUN (LUN ID 30), i find in the syslog this message: multipathd: 8:64: size 6835937472, expected 5267578112. Discard
Here is the multipath.conf
So I correctly see the two luns, but multipath doesn't create the relative devices. Under /dev/mapper I see: control mpath0 mpath0-part1 mpath0-part1 is the first lun, the one I mounted in a directory under filesystem. I can't find the device for the second lun
I rebooted my vServer (Debian 8) and it doesn't came back up. Well, I used the rescue console on my server and the server seems to be running fine, except the network was broken. So I tried 'ifconfig' but nothing came up. So I tried to enable my interface with 'ifconfig venet0 up', and now it appears in my ifconfig list
My HWaddr doesn't look that well :) 'ip addr' prints this result:
Code: Select allroot@i67svof:/var/www# ip addr 1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
These are the last lines in /var/log/syslog:

And finally my network config in /etc/network/interfaces

Upgraded webserver to Jessie as an upgrade to Wheezy produced errors, and before reboot everything was up and running, but as all upgrade docs and info I read, I rebooted the server. However it never came back. I have the original backup files before I did the Wheezy upgrade. I also have access by Rescue to the server.Made a back up of critical files and have a 24GB tar file and I can connect by SFTP.
how to check the Debian files... Grub etc.. I would prefer to find the issue than start again.I am not able to sudo from Putty. I cannot run apt-get update. I did go to chroot, but then I get unable to resolve host errors and Could not open lock file because Permission denied errors and asking if I am root.There is information by googling for start up issues, but as I am working remotely with a Rescue set up, a lot of the commands I see and have tied do not work.
A couple of days ago I asked why my pc changes the wireless card name.It switches between AR9285 ( right) and AR5008 ( wrong). Well, it is not the case. When system identified with AR9285,it loads ath9k and I can connect to the router. When system identifies my card as AR5008, no kernel module is present at all ( lspci -k). The wrong card name occurs only when system rebooted. If I gracefully shut down the system, it always comes up with a right name for the card( AR9285). So, how to force the system identify my card right no matter if I reboot or shut down?
