  • How to share text, pictures and video to restricted set of users

    - by joaoc
    I want to share pictures and videos of my kid growing up but I don't want it to be open to the public. I just want me and my wife to be able to add material and then share with grandparents and friends who would be given a username/password or some other solution that authenticates them. This content would preferably be available remotely over the internet or downloaded periodically to the allowed viewers computers. The second option most likely means they would have to install a client, which I am not too fond of doing (I would have to ask them to install it, help configure for different platforms, ...) I'm at the start but I would like software that also allows export of the data (if one day I want to migrate to a different solution). Folder sharing I don't know if Windows folder sharing is reliable, robust and safe enough to share over the internet. Dropbox could be a software solution, but it's limited to 2GB and requires receivers to also install and configure software. A folder is just a collection of files, so it would be harder to keep them organized with text describing the pictures/video Email I could email the content every now and then but videos are almost always too big to go as attachments This would also not provide a history of updates to anyone just recently joining in Are there other solutions to achieve this? NOTE: I also thought that software to run a local or remote blog could be an option but we aren't allowed to ask those questions on superuser because one admin doesn't like cloud-computing questions. But if you do think it's the best approach and can suggest a solution, do state it in the answers anyway!

  • Generic/Text Printer on Windows 7 not prompting for file name

    - by Trevor Tippins
    Hope someone can shed some light on this. I am downloading reports from an AIX-based system by directing them to a TT printer which the terminal emulator (MultiView 2000) intercepts and directs to the default printer on the local system. This local printer is configured as a vanilla Generic/Text printer attached to a FILE port. When I print from AIX, the output is spooled down and the local printer prompts for a file name into which to save the file...but not under Windows 7. This has worked fine for many years, on both Win2K and WinXP. However, on Windows 7 the output gets spooled as a file into spool\PRINTERS (and looks as expected) but the print job then hangs with a status of "Error - Printing" and never prompts for a file name. I have to cancel the job. The Generic/Text printer works as expected with other applications. I have tried setting the printer to print directly rather than spooling but this only serves to hang the terminal session too. I've also tried to run the emulator in Windows 2000 Compatibility Mode and as Administrator in case it was something like that but with no luck. As you might expect, it does work fine in XP Mode (as long as I print to a printer defined therein and not the host's printer) but operationally this isn't going to be an option. Obviously this emulation software is a decade old (at least) and I could just cross/upgrade all the users (at a cost) but, before I do so, has anyone seen this sort of behaviour before and found some sort of fix? Remote OS: AIX 5 Client OS: Windows 7 Pro (32-bit) Printer: Generic/Text on a FILE port TE Software: MultiView 2000 (32-bit) Thanks in advance.

  • Server Crash Diagnosis...Are there any 'black box recorder' style programs available.

    - by columbo
    My redhat server is crashing every three weeks or so at 4:15am ish on Sunday mornings. (well it was sundays the last two have been Thursday mornings at 4:15ish) Looking at the logs (mysql, httpd, messages) there are no clues as to why. They just seem to stop. I ran a little script to take memory readings every 15 minutes and it too stops (with normal readings) at this time. The server is remote at a provider so I can only access it via the web. I use Plesk. It appears to be a set job or something that is causing the issue. I can see nothing in crontab. So my question is...has anyone else had this and can offer advice? Failing that. Does any one know of a way to get more detailed logging than that offered by the messages file? I was thinking of a black box style recording program or maybe something as simple as an option somewhere to increase the level of reporting in the messages log. Thanks

  • Installing sphinx on a web hosting server

    - by fiftyeight
    I want to install sphinx search on a web-hosting server. I'm on a Linux VPS with hostgator, but I never actually installed anything on a remote server so this will be a first time for me. If there's anyone here who installed sphinx it's really help me I had some problems when using sphinx on my PC with the permissions and the MySQL files, eventually I got it working on my PC. Anyway, I'd me really grateful if anyone can help me with some questions Do i need root access to install sphinx? I have root access to the server but I'd connect to it as a normal user since doing stuff as root is always less secure. can anyone tell me by what user I need to execute the indexer and the search daemon? Should I use root access in order to this? when I did it as a normal user on my PC it gave me some trouble with the PID file and the log files. last time I executed the search deamon I executed it as a normal user and it gave me some trouble, I created the folder /var/log/ for log files and did chmod 777 on it, but still when I executed the search daemon it created the PID file "searchd.pid" file but with no permissions for some reason, any idea why? Thanx in advance. fiftyeight

  • VPN service into 192 network

    - by tophersmith116
    I'm thinking about setting up a security testing lab. I work on a switched network, and that just makes for unnecessary headaches when doing testing. I'd like to create a 192 network with a few machines inside for DBs and AppServers etc. I will need a pivot machine that connects to both the outer network and the 192 (for automation purposes). But I'd like to be able to connect into the 192 network with my own machine from the outer network as the "attacking" machine (rather than have dedicated attack machines inside the 192 network). Therefore, I'd like to have the pivot server be a VPN server as well, so that my machine can VPN into the 192 network from the outer network. First off, is this even possible? Can I have a single computer with two NICs where a VPN service allows remote connections into the 192? Secondly, I'd like to have multiple outer clients connect to the VPN. Does anyone have any suggestions? I've used Hamachi well before, but I've also seen some good stuff from OpenVPN.

  • Simple Distributed Disconnected way to sync a directory

    - by Rory
    I want to start regularly backup my home directory on my ubuntu laptop, machine X. Suppose I have access to 2 different remote (linux) servers that I can backup to, machines A & B. Machine X will be the master, and should be synced to A and B. I could just regularly run rsync from X to A and then from X to B. That's all I need. However I'm curious if there's a more bandwidth effecient, and hence faster way to do it. Assuming X is going to be on residential style broadband lines, and since I don't want to soak up the bandwidth, I would limit the transfer from X. A and B will be on all the time, however X, will not be, so I'd also like to reduce the amount of time that X is transfering, potentially allowing A and B to spend more time transfering. Also, X won't be connected all the time. What's the best way to do this? rsync from X to A, then from A to B? Timing that right could be troublesome. I don't want to keep old files around, so if I was to rsync, then the --del option would be used. Could that mean something might get tranfered from A to B, then deleted from B, then transfered from A to B again? That's suboptimal. I know there are fancy distributed filesystems like gluster, but I think that's overkill in this case, and might not fit with the disconnected nature.

  • Send command through PuTTY automatic login

    - by Arthur
    I am using the following to login automatically to a remote server and then run commands listed in a commands.txt, like this: C:\path to\putty.exe -ssh adreese.ip -l user -pw Password -m C:\Path to\command.txt commands.txt contains the following: wakeonlan -i broadcast adress Macadress However, when I try to do so a new window for PuTTY appears, but it closes and exits instantly after login. As a result, I cannot see the output of the command(s). After a several tests, it appears that the command is not execute , cause my computer doesn't "wake on lan". I don't understand what's going on here ? I cannot use the plink.exe program cause I cannot make connection with public key ( too much distant site for doing all the registration keys in putty ) Can someone help me with this ? Or can i use another program to make ssh connection and send command with script from a windows os? Edit : I also try to make a bash file in the distant server with the same command and execute it from the session like this : C:\path to\putty.exe -ssh adreese.ip -l user -pw Password \home\user\script.sh Ihave the same problem... Need help please : /

  • What can I do to determine the root cause of a Windows server hanging/freezing?

    - by Aaronaught
    We set up a new server here a few weeks ago that I am informally responsible for managing. Almost everything works perfectly except for one thing: Every so often it hangs without warning. To clarify: When I say hangs, I mean completely. None of the services respond and I'm unable to even get onto a local console - the display acts as though there's no VGA signal. One time, the server actually responded to pings, another time I got the "destination host unreachable" response, but most of the time the pings just time out, as one would expect for a hung server. Event logs don't show anything after a reboot. I don't mean that they don't show anything interesting, I mean that they don't show anything at all from before the failure occurs to after the reboot. And there are never any performance problems, strange errors, or other obvious signs of impending doom before it happens. I don't expect any easy answers here. What I'd like to know his I can methodically determine the root cause of this problem, be it a misbehaving service, defective hardware, or something else. Is there any kind of logging I can set up that will help me get to the bottom of this? Any hardware diagnostics or remote monitoring? Anything else I can do to help me discover what's actually happening, or at least be able to eliminate what isn't wrong? Just to reiterate, I really don't want to start speculating about possible causes and take a trial-and-error approach, because it's going to be at least several days at a time before I would have conclusive results. I'm looking for solutions to reliably trace the problem to its source.

  • Power Outage Interrupted Upgrade from Windows Vista Ultimate to 7 Ultimate, Reverted to Vista, Now Vista is failing... What Next?

    - by tednewk
    I was in the midst of what seemed to be a successful upgrade from Vista Ultimate to 7 Ultimate when there was a brief blackout. The upgrade failed and Windows reverted back to Vista. Now Vista is very slow to boot, has problems waking back-up from inactivity and quickly loses it's wireless connection. The wake-up problem manifests itself as the mouse is clearly shown on a black screen but I have no access to the Desktop or Taskbar or Explorer. Even Alt-Ctrl-Delete doesn't seem to work. No task menu, no reboot. Hitting the reset button reboots the machine with the usual Black Screen warnings offering Safe Mode. I tried to do a system restore to a point before the upgrade. That didn't seem to work. My guess is that my system is a mutant with parts of Vista and parts of 7 crashing each other. I would like avoid a clean install if at all possible to avoid reinstalling other software. What should I try now? My thoughts are: My a system back-up to lock the computer in place Trying a second 7 upgrade If that appears to be working make another back-up If not reload back-up and try a repairing Vista from DVD. If that appears to work make another back-up, let system stablize about a week then try 7 install again If that doesn't work are there any other options to try before settling for a clean install? Another complication, I am doing this by "remote control". I'm traveling with my job and I'll be talking my son through it over the phone. (Kind of like the landing the 747 cliche from all the 70's adventure shows!) So is there a way of simplifying the steps? Thanks Ted

  • PuTTY inserts random characters during a session

    - by Zachary Polikarpus
    I recently started renting space on a remote server so that I could work on a project. I found that a relatively painless way to access it on a windows machine is through PuTTY. However, there is one thing that has always irked me when using it: for seemingly no reason random characters are sometimes inserted at the cursor. Most of the time it is just a single tilde, but rarely it spits out what looks like some escape sequence ([[^8 or the like). It will only occur when I am focused on the window, whether I am typing or 20 feet away from the keyboard. If left for long enough, it will spit tildes at random intervals (average is about 1 minute). Finally, this behavior seems to be inconsistant when running programs such as nano or the mysql interface: in nano, instead of inserting tildes, it will set marks (ctrl-^); in mysql, lines will become un-editable. My question is this: Has anyone else experienced this sort of behavior in PuTTY? And if so, what can be done to prevent/correct this behavior?

  • Shoretel Upgrade Path

    - by Brian
    I currently have a Shoretel Server running Server 2003 x32 as a virtual machine paired with a ShoreGear 90 switch and another unused switch of the same model being reserved for manual failover. I am getting the software mailed to me from my partner, but with limited support since the server is in a relatively remote area. I am tempted to upgrade the OS at the same time as performing the upgrade, but want to know if there are any horror stories or advice I should know about before diving in. I'm upgrading from Shoretel 9.2 Build. I will be upgrading first to version 10.1 then finally to 11.1. The system has been bullet proof since it was installed and we are upgrading mainly to get a client that is a little more modern. My question boils down to: Should I even bother with an OS upgrade or even possibly a fresh install of Windows with an install of Shoretel 11.1 and just transfer the configuration? Should I just stay with Server 2003 since it is supported in my target version of Shoretel and the upgrade will be more than enough to keep me busy as a novice?

  • Jailkit not locking down SFTP, working for SSH

    - by doublesharp
    I installed jailkit on my CentOS 5.8 server, and configured it according to the online guides that I found. These are the commands that were executed as root: mkdir /var/jail jk_init -j /var/jail extshellplusnet jk_init -j /var/jail sftp adduser testuser; passwd testuser jk_jailuser -j /var/jail testuser I then edited /var/jail/etc/passwd to change the login shell for testuser to be /bin/bash to give them access to a full bash shell via SSH. Next I edited /var/jail/etc/jailkit/jk_lsh.ini to look like the following (not sure if this is correct) [testuser] paths= /usr/bin, /usr/lib/ executables= /usr/bin/scp, /usr/lib/openssh/sftp-server, /usr/bin/sftp The testuser is able to connect via SSH and is limited to only view the chroot jail directory, and is also able to log in via SFTP, however the entire file system is visible and can be traversed. SSH Output: > ssh testuser@server Password: Last login: Sat Oct 20 03:26:19 2012 from x.x.x.x bash-3.2$ pwd /home/testuser SFTP Output: > sftp testuser@server Password: Connected to server. sftp> pwd Remote working directory: /var/jail/home/testuser What can be done to lock down SFTP access to the jail? FWIW, I mostly used this as a guide: http://digitalpatch.blogspot.com.ar/2010/03/openssh-daemon-hardening-part-3-setup.html

  • Browsing \\computer\share fails, but net use \\computer\share works?

    - by JMD
    I've had mixed results with using Windows Explorer to browse remote file shares. The setup: I'm at work on Windows XP SP3 Files are at home on Windows XP SP3 Two separate VPNs are available to access my PC at home corporate OpenVPN (10.1.2.3) a Hamachi/LogMeIn connection (5.1.2.3) With respect to my problem, it doesn't matter which IP I use. They both perform exactly the same way: I expect that if I open Windows Explorer and type in \\10.1.2.3\Shared I should be interrupted with a challenge for credentials, and then be able to interact with the files in the share. However, I just get that annoying dialog, "Windows cannot find '\10.1.2.3\Shared' Check the spelling and try again, or try searching for the item ..." However, I can take that exact same computername/sharename and with net use I can: net use * \\10.1.2.3\Shared * /user:homecomputername\username with this result: Type the password for \\5.69.83.158\C$: Drive Z: is now connected to \\5.69.83.158\C$. The command completed successfully. I can then access the files in Z: in Windows Explorer which was my original intent. Even after Z: is already mapped and the credentials are cached I still cannot bring up \\10.1.2.3\Shared in Windows Explorer. Why does the latter work, but not the former? Edit: Other services work fine, such as RDP. (I have a problem in which I can't SSH home, but I'll consider that separately.)

  • VMWare web UI intermittent access on CentOS

    - by PeteWilliams
    Hiya, I've got a CentOS 5.2 server that I'm trying to get set up as a development environment. As part of this, I planned to install VMWare Server 2 and set up several virtual development servers. I've got as far as installing VMWare Server 2 but access to the remote control panel is only working intermittently. If I access it through Firefox at https://127.0.0.1:8333/ui/# it usually says either: "Connection intterupted: connection was reset before the page loaded" Or "Firefox can't establish a connection to the server at 127.0.0.1" But every now and then it lets me in and I'll manage a few clicks in the web UI before it kicks me out with the following error: "The server could not complete a request (HTTP 0 ). The server encountered an unexpected condition that prevented it from fulfilling the request. If this problem persists, please contact your system administrator." I've done all the updates available in CentOS except one OpenOffice one that is causing a conflict, and I re-ran wmware-config.pl after updating the kernel. Though I went with all the defaults as I don't really know what I'm doing! I've since rebooted and nothing changed. I've also tried accessing the control panel remotely from another machine in the network and the results are the same. Does anyone have any ideas what might be causing this and how I can resolve it? I'm afraid I'm a developer playing at sys-admin, so I may be missing something obvious! Many thanks Pete Update I have now reinstalled both the operating system and VMWare and I'm still getting the same issue. I wonder if it's a result of the settings I'm putting in on the config.pl script..?

    the main programmer for SoEasyAccounting and we are installing to Server 2008 Standard service pack 1. We install to 2003 with no problems. Important to understand that the print failure only happens in certain circumstances: Note: We use a standard Windows printer selection box to choose the printer Terms used Superbase = a program language that uses ntvdm.exe (Windows process hosting 16 bit apps) Local Printer = printing to a driver loaded onto the Server 2008 Redirect Printer = printing to a automatically established remote printer through an RDP connection Printing Scenarios Server 2008 - 1: Print from notepad to a Redirected Printer = works Server 2008 - 2: Print from Superbase to a Local Printer = works Server 2008 - 3: Print from Superbase to a Redirected Printer = fail Server 2003 - 4: Print from Superbase to a Redirected Printer = works Results The print causes a message in the drivers print queue of Local Downlevel Document, no print though and Superbase recognises that the "Print command failed". Eventvwr has no related issues to the print fail Any help greatly appreciated. So far 2 days spent trying to resolve and here goes my weekend :( unless someone has an idea :) Things I have Tried i. Switching on/off Easy print ii. Loading copy of redirected driver on server

  • Cisco ASA user authentication options - OpenID, public RSA sig, others?

    - by Ryan
    My organization has a Cisco ASA 5510 which I have made act as a firewall/gateway for one of our offices. Most resources a remote user would come looking for exist inside. I've implemented the usual deal - basic inside networks with outbound NAT, one primary outside interface with some secondary public IPs in the PAT pool for public-facing services, a couple site-to-site IPSec links to other branches, etc. - and I'm working now on VPN. I have the WebVPN (clientless SSL VPN) working and even traversing the site-to-site links. At the moment I'm leaving a legacy OpenVPN AS in place for thick client VPN. What I would like to do is standardize on an authentication method for all VPN then switch to the Cisco's IPSec thick VPN server. I'm trying to figure out what's really possible for authentication for these VPN users (thick client and clientless). My organization uses Google Apps and we already use dotnetopenauth to authenticate users for a couple internal services. I'd like to be able to do the same thing for thin and thick VPN. Alternatively a signature-based solution using RSA public keypairs (ssh-keygen type) would be useful to identify user@hardware. I'm trying to get away from legacy username/password auth especially if it's internal to the Cisco (just another password set to manage and for users to forget). I know I can map against an existing LDAP server but we have LDAP accounts created for only about 10% of the user base (mostly developers for Linux shell access). I guess what I'm looking for is a piece of middleware which appears to the Cisco as an LDAP server but will interface with the user's existing OpenID identity. Nothing I've seen in the Cisco suggests it can do this natively. But RSA public keys would be a runner-up, and much much better than standalone or even LDAP auth. What's really practical here?

  • How can I monitor VNC via Nagios?

    - by atroon
    I have a number of remote sites which have VNC running on a few computers for support purposes. They are (obviously) only available on our internal network. I am using Nagios to keep track of all the systems in the network and I want to have it check to make sure the VNC server is running on the appropriate hosts. There is a 'check_vnc' plugin available here but it relies on VNC Snapshot which I don't want to use. Certainly I could use it, but it adds more complexity and dependency, which I want to avoid. It seems simpler to just use check_tcp to make sure I get the proper response to a connection request for VNC, e.g. port 5900, send a connect string, get back framebuffer info. My real question, I suppose, is this: What is the 'proper' generic connect string for VNC (I use both UltraVNC and RealVNC) and what is the expected response? If it's really easier to use the VNC Snapshot and check_vnc, let me know. I just can't imagine that a string of text isn't easier, faster, and less bandwidth intensive to monitor.

  • Windows VPN always disconnects after < 3 minutes, only from my network

    - by hemp
    First, this problem has existed for almost two years. Until serverfault was born, I pretty much gave up on solving it - but now, hope is reborn! I've set up a Windows 2003 server as a domain controller and VPN server at a remote office. I am able to connect to and work over the VPN from every windows client I've tried, including XP, Vista, and Windows 7 without issue, from at least five different networks (corporate and home, domain and non.) It works fine from all of them. However, whenever I connect from clients on my home network, the connection drops (silently) after 3 minutes or less. After a short while, it will eventually tell me the connection has dropped and attempt to redial/reconnect (if I've configured the client that way.) If I reconnect, the connection will re-establish and appear to work correctly, but again will silently drop, this time after a seemingly shorter time period. These are not intermittent drops. It happens every single time, in exactly the same way. The only variable is how long the connection survives. It doesn't matter what type of traffic I send. I can sit idle, send continuous pings, RDP, transfer files, all of that at once - it makes no difference. The result is always the same. Connected for a few minutes, then silent death. Since I doubt anyone has experienced this exact situation, what steps can I take to troubleshoot my evanescing VPN?

  • Device CAL, User Cal or Processor license needed for SQL 2008 (architecture explained inside)?

    - by nycgags
    So we have a number of servers in the Amazon cloud running SQL Server Standard edition to aggregate data. For that purpose we are fine, the licensing is handled by our contract with Amazon, no problem there. For the beefier work, we want to install Enterprise Edition (EE) on our servers processing raw data so that we can take advantage of table partitioning. We currently have 3 servers aggregating data from about 40 node servers, all 43 of these servers are running standard edition which is fine. We also have 4 servers running standard processing the raw data, but I think we can get away with 2 (for redundancy) running Enterprise Edition. We have 2-3 dba's that access these DW servers for maintenance (using the same windows login via remote desktop). So visually: 40 -- 3 -- [2] -- 2 -- 1 nodes -- aggregators -- raw (which we want to run EE) -- calculators -- datawarehouse Nodes PUSH to aggregators, Raws PULL from aggregators, Calculators PULL from Raw, Calculators PUSH to datwarehouse I am specifying the push vs. pull in case that changes how the # of licenses is calculated. Q1) how many device (or user) CAL's do we need? Q2) do I need to speak with someone from MSFT to find out if it is ok to install in the Amazon Cloud (Amazon said we need to verify it is ok in our license terms)? Q3) what happens if another device tries to access a server with the limited number of device CAL's? Q4) Are the device CAL's simultaneous number of devices or total? Q5) Do Device and User CAL's cost the same or is there a difference? Q6) Would we need to buy a processor license (we are hoping not to)?

  • Login failed for user 'XXX' on the mirrored sql server

    - by hp17
    Hello, We have 4 web servers that host our asp.net (3.5) application. Randomly, we get error messages like : 1) "Login failed for user 'userid'" 2) "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)" we are running sql2005 and have a principle and a mirror db (sync). When these exceptions are thrown, I look at the SQL error logs on the mirrored db and noticed the failed login messages in there. The principle db is running fine and the other web apps are working great. this will happen for maybe 10 min, then the app pool recycles and it starts hitting the principle db again. Is there a configuration I have incorrect? my theory is that our principle db is forwarding the request to the mirror, but that should never happen. any help??

  • Random server lag, no CPU/mem/pagefile usage

    - by Kev
    We have a fairly new server running Windows 2003 SP2, and the past few days we've noticed random slowdowns. When I'm logged into the server over remote desktop while this is happening, or if I'm physically sitting at the server logged in, suddenly everything becomes extremely laggy. Any UI element I try to interact with takes upwards of ten seconds to react, and then responds very slowly. Then a minute later everything is quite snappy again. During this, I have Task Manager minimized to the tray, and there's no CPU usage. I open it up right after this happens, and there's very little CPU usage on the graph, and no memory or pagefile usage above normal. (Normal being 1.5 GB free in the case of memory.) This is what I see logged into the server, and then users start calling saying things are slow, timing out, and failing--anything to do with our server. No events in the Event Viewer around the times this happens. The context I'm working in (last thing I clicked, etc.) seems different every time--different programs active, different combinations of programs open. Never anything particularly stressful (like adding an event entry to a Cobian Backup configuration, or editing text in TextPad, which has been exceptionally stable in my extensive usage of it.) I would've thought it was just the server, but a family member's home PC (entirely separate) running WinXPSP3 had the same thing happen to it last night a few times. Is this some new behaviour introduced by the latest Windows Updates? Either way, where do I even start to look when nothing seems to be chewing up resources?

  • Help trying to figure out why IIS7 is crashing / locking up / denying connections

    - by Pure.Krome
    Hi folks, I've got a pretty busy website that is running on a single web front end machine, on W2K8 + IIS7. Every now and then - eg. maybe monday at 3am or something, then a few days later .. some early morning time .. then nothing for 2 weeks ... etc - the website fails to respond to any client connections. ie. no one can connect to the website. I can remote desktop to the machine, etc no probs. I restart the app pool (the website is running in intergrated mode), still nothing. I try and get a crash dump of the process (it's around 600 mb maybe even more) ... that fails after about a min of trying (and i have plenty of HD space). The only way to fix this issue, is to manually stop the www service and then start it again. The stopping takes a while (a minute?) while starting is nearly instant. I'm at a loss to figure out what part of my code is causing this. At first, I thought it might be a stack overflow because of some error that might be going to the error page, which in turn errors .. rinse repeat boom. But i've had a look at the error page and it feels ok. So, I'm hoping someone might be able to help and say how I can correctly get a proper dump of the IIS process so i can then do some more autopsy on it. I would email Tess Ferrandez (the goddess of crash debuging) but I thought I'd try here before I spam her. Can anyone have any suggestions to how I can figure out how to start to debug this issue?

  • backup an existing linux server to a virtualbox virtual machine

    - by user146526
    I have some servers and VPSs to many companies across the world. I want to back them up locally. I have some backup solutions enabled to remote hosts, but I want to have a local backup on a computer at home. What I am thinking is: 1) Create a virtualbox virtual machine, install the same version linux as the server. 2) Use rsync to backup the server to the local virtualbox machine. (something like rsync -av --delete --progress --exclude '/dev/' --exclude '/proc/' root@server_ip:// / ) 3) Repeat the command every few days update files. 4) In case of a hard disk failure, or any other bad event, reverse the rsync command and get the files back and continue my bussiness. I tried it with 2 openvz VPS, the one was a backup of the other. I also tried to transfer normal linux server host to openvz machine and it worked great. That way looks pretty clean and easy to me, this is the kind of solution I am looking for. However I need to be sure that this will work if I am going to do it. The question is, will that work ok ? Does anyone see any problem with that ? Do you have any other suggestions ? Thanks

  • Not able to connect to port different than 22 - OpenVPN

    - by t8h7gu
    I have OpenVPN network with 5 clients. Computer with Arch Linux which hosts OpenVPN server, It also hosts virtual machine with Computer with CentOS which is also connnected to OpenVPN subnet. Windows 8 which hosts virtual machine with CentOS. Both of them are connected to OpenVPN. Last one machine is virtual machine with CentOS which is hosted by computer with Ubuntu 14( which is not connected to OpenVPN. All machines in OpenVPN subnet are bolded. All phisical computers are in different networks. The problem is that when I use nmap to scan Windows and it's guest virtual machine it's saids that host seems down. When I force namp to scan specific port it shows filtered state: nmap -Pn -p 50010 n3 Starting Nmap 6.46 ( http://nmap.org ) at 2014-06-07 19:49 CEST Nmap scan report for n3 (10.8.0.3) Host is up (0.11s latency). rDNS record for 10.8.0.3: node3.com PORT STATE SERVICE 50010/tcp filtered unknown Telnet also cannot connect to this port telnet n3 50010 Trying 10.8.0.3... telnet: Unable to connect to remote host: No route to host But ss on this host show's proper state of this port ss -anp | grep 50010 LISTEN 0 50 10.8.0.3:50010 *:* users:(("java",12310,271)) What might be possible reason of that and how to fix it? EDIT I've found that I am able to connect via telnet to ssh port: telnet n3 22 Trying 10.8.0.3... Connected to n3. Escape character is '^]'. SSH-2.0-OpenSSH_5.3 So it seems that it's not problem with Windows firewall. But I have no idea what it might be. Also nmap result for first thousand ports: nmap -Pn -p 1-1000 n3 Starting Nmap 6.46 ( http://nmap.org ) at 2014-06-07 20:08 CEST Nmap scan report for n3 (10.8.0.3) Host is up (0.49s latency). rDNS record for 10.8.0.3: node3.com Not shown: 999 filtered ports PORT STATE SERVICE 22/tcp open ssh Nmap done: 1 IP address (1 host up) scanned in 77.87 seconds
