  • Problems setting up a VPN: can connect but can't ping anyone

    - by Fernando
    This is my first time setting a VPN. Clients can connect but can't ping other machines. This is certainly a route problem but i can't find the right way to configure it. Here is a sample example of the two LANS i want to connect: So, i want machines from 192.168.1.0/24 being able to connect with 192.168.0.0/24 as if they were on the same network. For the VPN network, i would like to use the 10.0.0.0/24 range. Here is my server.conf: proto udp port 1194 dev tun server 10.0.0.0 255.255.255.0 push "route 192.168.0.0 255.255.255.0 192.168.0.1" push "dhcp-option DNS 192.168.0.1" push "dhcp-option WINS 192.168.0.1" comp-lzo keepalive 10 120 float max-clients 10 persist-key persist-tun log-append /var/log/openvpn.log verb 6 tls-server dh /etc/openvpn/keys/dh1024.pem ca /etc/openvpn/keys/ca.crt cert /etc/openvpn/keys/server.crt key /etc/openvpn/keys/server.key tls-auth /etc/openvpn/keys/mykey.key 0 status /var/log/openvpn.stats And one of my clients 192.168.1.2: client dev tap proto udp remote my.no-ip.address 1194 route 192.168.1.0 255.0.0.0 192.168.1.1 3 resolv-retry infinite nobind persist-key persist-tun ca "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\ca.crt" cert "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\test1.crt" key "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\test1.key" tls-auth "C:\\Program Files\\OpenVPN\\easy-rsa\\keys\\mykey.key" 1 ns-cert-type server cipher BF-CBC comp-lzo verb 1 What exactly i am doing wrong? All machines can connect to openvpn but the ping doesn't work. At the client log i see the following error: Wed Feb 16 09:43:23 2011 OpenVPN ROUTE: OpenVPN needs a gateway parameter for a --route option and no default was specified by either --route-gateway or --ifconfig options Wed Feb 16 09:43:23 2011 OpenVPN ROUTE: failed to parse/resolve route for host/network: 10.0.0.1 Thanks!

  • Move Files from a Failing PC with an Ubuntu Live CD

    - by Trevor Bekolay
    You’ve loaded the Ubuntu Live CD to salvage files from a failing system, but where do you store the recovered files? We’ll show you how to store them on external drives, drives on the same PC, a Windows home network, and other locations. We’ve shown you how to recover data like a forensics expert, but you can’t store recovered files back on your failed hard drive! There are lots of ways to transfer the files you access from an Ubuntu Live CD to a place that a stable Windows machine can access them. We’ll go through several methods, starting each section from the Ubuntu desktop – if you don’t yet have an Ubuntu Live CD, follow our guide to creating a bootable USB flash drive, and then our instructions for booting into Ubuntu. If your BIOS doesn’t let you boot using a USB flash drive, don’t worry, we’ve got you covered! Use a Healthy Hard Drive If your computer has more than one hard drive, or your hard drive is healthy and you’re in Ubuntu for non-recovery reasons, then accessing your hard drive is easy as pie, even if the hard drive is formatted for Windows. To access a hard drive, it must first be mounted. To mount a healthy hard drive, you just have to select it from the Places menu at the top-left of the screen. You will have to identify your hard drive by its size. Clicking on the appropriate hard drive mounts it, and opens it in a file browser. You can now move files to this hard drive by drag-and-drop or copy-and-paste, both of which are done the same way they’re done in Windows. Once a hard drive, or other external storage device, is mounted, it will show up in the /media directory. To see a list of currently mounted storage devices, navigate to /media by clicking on File System in a File Browser window, and then double-clicking on the media folder. Right now, our media folder contains links to the hard drive, which Ubuntu has assigned a terribly uninformative label, and the PLoP Boot Manager CD that is currently in the CD-ROM drive. Connect a USB Hard Drive or Flash Drive An external USB hard drive gives you the advantage of portability, and is still large enough to store an entire hard disk dump, if need be. Flash drives are also very quick and easy to connect, though they are limited in how much they can store. When you plug a USB hard drive or flash drive in, Ubuntu should automatically detect it and mount it. It may even open it in a File Browser automatically. Since it’s been mounted, you will also see it show up on the desktop, and in the /media folder. Once it’s been mounted, you can access it and store files on it like you would any other folder in Ubuntu. If, for whatever reason, it doesn’t mount automatically, click on Places in the top-left of your screen and select your USB device. If it does not show up in the Places list, then you may need to format your USB drive. To properly remove the USB drive when you’re done moving files, right click on the desktop icon or the folder in /media and select Safely Remove Drive. If you’re not given that option, then Eject or Unmount will effectively do the same thing. Connect to a Windows PC on your Local Network If you have another PC or a laptop connected through the same router (wired or wireless) then you can transfer files over the network relatively quickly. To do this, we will share one or more folders from the machine booted up with the Ubuntu Live CD over the network, letting our Windows PC grab the files contained in that folder. As an example, we’re going to share a folder on the desktop called ToShare. Right-click on the folder you want to share, and click Sharing Options. A Folder Sharing window will pop up. Check the box labeled Share this folder. A window will pop up about the sharing service. Click the Install service button. Some files will be downloaded, and then installed. When they’re done installing, you’ll be appropriately notified. You will be prompted to restart your session. Don’t worry, this won’t actually log you out, so go ahead and press the Restart session button. The Folder Sharing window returns, with Share this folder now checked. Edit the Share name if you’d like, and add checkmarks in the two checkboxes below the text fields. Click Create Share. Nautilus will ask your permission to add some permissions to the folder you want to share. Allow it to Add the permissions automatically. The folder is now shared, as evidenced by the new arrows above the folder’s icon. At this point, you are done with the Ubuntu machine. Head to your Windows PC, and open up Windows Explorer. Click on Network in the list on the left, and you should see a machine called UBUNTU in the right pane. Note: This example is shown in Windows 7; the same steps should work for Windows XP and Vista, but we have not tested them. Double-click on UBUNTU, and you will see the folder you shared earlier! As well as any other folders you’ve shared from Ubuntu. Double click on the folder you want to access, and from there, you can move the files from the machine booted with Ubuntu to your Windows PC. Upload to an Online Service There are many services online that will allow you to upload files, either temporarily or permanently. As long as you aren’t transferring an entire hard drive, these services should allow you to transfer your important files from the Ubuntu environment to any other machine with Internet access. We recommend compressing the files that you want to move, both to save a little bit of bandwidth, and to save time clicking on files, as uploading a single file will be much less work than a ton of little files. To compress one or more files or folders, select them, and then right-click on one of the members of the group. Click Compress…. Give the compressed file a suitable name, and then select a compression format. We’re using .zip because we can open it anywhere, and the compression rate is acceptable. Click Create and the compressed file will show up in the location selected in the Compress window. Dropbox If you have a Dropbox account, then you can easily upload files from the Ubuntu environment to Dropbox. There is no explicit limit on the size of file that can be uploaded to Dropbox, though a free account begins with a total limit of 2 GB of files in total. Access your account through Firefox, which can be opened by clicking on the Firefox logo to the right of the System menu at the top of the screen. Once into your account, press the Upload button on top of the main file list. Because Flash is not installed in the Live CD environment, you will have to switch to the basic uploader. Click Browse…find your compressed file, and then click Upload file. Depending on the size of the file, this could take some time. However, once the file has been uploaded, it should show up on any computer connected through Dropbox in a matter of minutes. Google Docs Google Docs allows the upload of any type of file – making it an ideal place to upload files that we want to access from another computer. While your total allocation of space varies (mine is around 7.5 GB), there is a per-file maximum of 1 GB. Log into Google Docs, and click on the Upload button at the top left of the page. Click Select files to upload and select your compressed file. For safety’s sake, uncheck the checkbox concerning converting files to Google Docs format, and then click Start upload. Go Online – Through FTP If you have access to an FTP server – perhaps through your web hosting company, or you’ve set up an FTP server on a different machine – you can easily access the FTP server in Ubuntu and transfer files. Just make sure you don’t go over your quota if you have one. You will need to know the address of the FTP server, as well as the login information. Click on Places > Connect to Server… Choose the FTP (with login) Service type, and fill in your information. Adding a bookmark is optional, but recommended. You will be asked for your password. You can choose to remember it until you logout, or indefinitely. You can now browse your FTP server just like any other folder. Drop files into the FTP server and you can retrieve them from any computer with an Internet connection and an FTP client. Conclusion While at first the Ubuntu Live CD environment may seem claustrophobic, it has a wealth of options for connecting to peripheral devices, local computers, and machines on the Internet – and this article has only scratched the surface. Whatever the storage medium, Ubuntu’s got an interface for it!

  • OpenVPN Bridge LAN-to-LAN Configuration?

    - by Shad Reese
    I'm trying to configure an OpenVPN bridge LAN-to-LAN setup. Currently, I have the OpenVPN bridge Server/Client setup up running. On the server-side my br-lan interface has tap0, eth0, and wlan0 in the bridge group. On the client-side the br-lan interface has eth0 and wlan0 in the bridge group, the client tap0 is outside of the br-lan group. Currently the two bridge groups are connected via the wlanO interfaces (server-side is the Access Point - AP and the client-side is the wireless client). My goal is to connect the two bridge groups with a wireless VPN pipe. My network configuration: Server: br-lan: 10.4.96.50 Client: br-lan: 10.4.96.75 tap0: 10.4.96.100 <---- issued by the VPN server. Unfortunately, I'm stuck with using a bridge instead of a routed OpenVPN setup. My question is how (if possible) do I add the client tap0 interface to the client bridge group, as to ensure all traffic between the server/client bridge groups is using the VPN pipe? SERVER CONFIG FILE. config openvpn sample_server # Set to 1 to enable this instance: option enable 1 option port 1194 option proto udp option dev tap0 option key /etc/easy-rsa/keys/server.key option dh /etc/easy-rsa/keys/dh1024.pem option ifconfig_pool_persist /tmp/ipp.txt option server_bridge "10.4.96.50 255.255.255.0 10.4.96.100 10.4.96.200" list push "redirect-gateway local def1" list push "dhcp-option DNS 10.4.96.14" option duplicate_cn 1 option comp_lzo 1 option max_clients 100 option log /tmp/openvpn.log option verb 3 CLIENT CONFIG FILE: config 'openvpn' 'sample_client' option 'enable' '1' option 'client' '1' option 'dev' 'tap' option 'proto' 'udp' list 'remote' '10.4.96.50 1194' option 'status' /tmp/openvpn-status.log option 'log' /tmp/openvpn.log option 'ca' '/etc/easy-rsa/keys/ca.crt' option 'cert' '/etc/easy-rsa/keys/client.crt' option 'key' '/etc/easy-rsa/keys/client.key' option 'comp_lzo' '1' option 'verb' '5' Thanks in advance,

  • How do I enable the confluence-users group?

    - by M. Joanis
    I've got an issue with Atlassian Confluence. Normal users can't log in, but administrators can... Details below! I manage users using an Apple Open Directory (LDAP). I created two groups: "confluence-administrators" and "confluence-users". I've added team leaders and managers to both groups, and I've added some users to "confluence-users". Everyone in "confluence-administrators" can log in easily. People in "confluence-users" can't log in at all. When I look at the user list (in Confluence), and select a user to examine the list of groups he or she belongs to, I can see that the Confluence Administrators are indeed members of the "confluence-administrators" group, but not a single user is a member of the "confluence-users" group. Not event the Confluence Administrators, which are members of both groups! So I tried to have one of the "confluence-users" log in while watching the Confluence logs. Here's the result: 2012-07-05 14:50:19,698 ERROR [http-8090-11] [core.event.listener.AutoGroupAdderListener] handleEvent Could not auto add user to group: Group <confluence-users> is read-only and cannot be updated at com.atlassian.crowd.directory.DbCachingRemoteDirectory.addUserToGroup(DbCachingRemoteDirectory.java:461) ... So it says the group group is read-only... I'm not sure why it is a problem. Well confluence-administrators too is read-only and it doesn't complain. Some things I don't think are part of the problem: I've synchronized Confluence with LDAP many, many times. I have verified many times that I didn't make a typo while setting the groups on the LDAP server. LDAP synchronization goes well. No errors in the logs (only INFO level log messages). The user exists. Errors in the logs are different when a user doesn't exist. Any help is most welcome!

  • svnstat script

    - by Kyle Hodgson
    So I'm building out a shell script to check out all of our relevant svn repositories for analysis in svnstat. I've gotten all of this to work manually, now I'm writing up a bash script in cygwin on my Vista laptop, as I intend to move this to a Linux server at some point. Edit: I gave up on this and wrote a simple .bat script. I'll figure out the Linux deployment some other way. Edit: added the sleep 30 and svn log commands. I can tell now, with the svn log command, that it's not getting to the svn log ... this time, it did Applications, and ran the log, and then check out Database, and froze. I'll put the sleep 30 before and after the log this time. co2.sh #!/bin/bash function checkout { mkdir $1 svn checkout svn://dev-server/$1 $1 svn log --verbose --xml >> svn.log $1 sleep 30 } cd /cygdrive/c/Users/My\ User/Documents/Repos/wc checkout Applications checkout Database checkout WebServer/www.mysite.com checkout WebServer/anotherhost.mysite.com checkout WebServer/AnotherApp checkout WebServer/thirdhost.mysite.com checkout WebServer/fourthhost.mysite.com checkout WebServer/WebServices It works, for the most part - but for some reason it has a tendency to stop working after a few repositories, usually right after finishing a repository before going to the next one. When it fails, it will not recover on its own. I've tried commenting out the svn line, it goes in and creates all the directories just fine when I do that - so its not that. I'm looking for direction as well as direct advice. Cygwin has been very stable for me, but I did start using the native rxvt instead of "bash in a cmd.exe window" recently. I don't think that's the problem, as I've left top on remote systems running all night and rxvt didn't seem to mind. Also I haven't done any bash scripting in cygwin so I suppose this might not be recommended; though I can't see why not. I don't want all of WebServer, hence me only checking out certain folders like that. What I suspect is that something is hanging up the svn checkout. Any ideas here? Edit: this time when I hit ctrl+z to cancel out, I forgot I was on Windows and typed ps to see if the job was still running; and as you can see there are lots of svn processes hanging around... strange.

  • Fixing my SQL Directory NTFS ACLS

    - by Shawn Cicoria
    I run my development server by boot to VHD (Windows Server 2008 R2 x64).  In that instance, I also have an attached VHD (I attach via script at boot up time using Task Scheduler).  That VHD I have my SQL instances installed. So, the other day, acting hasty, I chmod my ACLS – wow, what a day after that. So, in order to fix it I created this set of BAT commands that resets it back to operational state – not 100% of all what you get, I also didn’t want to run a “repair” – but, all operational again. setlocal SET Inst100Path=H:\Program Files\Microsoft SQL Server\100 REM GOTO SQLE SET InstanceName=MSSQLSERVER SET InstIdPath=H:\Program Files\Microsoft SQL Server\MSSQL10.%InstanceName% SET Group=SQLServerMSSQLUser$SCICORIA-HV1$%InstanceName% SET AgentGroup=SQLServerSQLAgentUser$SCICORIA-HV1$%InstanceName% ICACLS "%InstIdPath%\MSSQL" /T /Q /grant "%Group%":(OI)(CI)FX ICACLS "%InstIdPath%\MSSQL\backup" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\data" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\FTdata" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\Jobs" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\binn" /T /Q /grant "%Group%":(OI)(CI)RX ICACLS "%InstIdPath%\MSSQL\Log" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%Inst100Path%" /T /Q /grant "%Group%":(OI)(CI)RX ICACLS "%Inst100Path%\shared\Errordumps" /T /Q /grant "%Group%":(OI)(CI)RXW ICACLS "%InstIdPath%\MSSQL" /T /Q /grant "%AgentGroup%":(OI)(CI)RX ICACLS "%InstIdPath%\MSSQL\binn" /T /Q /grant "%AgentGroup%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\Log" /T /Q /grant "%AgentGroup%":(OI)(CI)F ICACLS "%Inst100Path%" /T /Q /grant "%AgentGroup%":(OI)(CI)RX REM THIS IS THE SQL EXPRESS INSTANCE :SQLE SET InstanceName=SQLEXPRESS SET InstIdPath=H:\Program Files\Microsoft SQL Server\MSSQL10.%InstanceName% SET Group=SQLServerMSSQLUser$SCICORIA-HV1$%InstanceName% SET AgentGroup=SQLServerSQLAgentUser$SCICORIA-HV1$%InstanceName% ICACLS "%InstIdPath%\MSSQL" /T /Q /grant "%Group%":(OI)(CI)FX ICACLS "%InstIdPath%\MSSQL\backup" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\data" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\FTdata" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\Jobs" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\binn" /T /Q /grant "%Group%":(OI)(CI)RX ICACLS "%InstIdPath%\MSSQL\Log" /T /Q /grant "%Group%":(OI)(CI)F ICACLS "%Inst100Path%" /T /Q /grant "%Group%":(OI)(CI)RX ICACLS "%Inst100Path%\shared\Errordumps" /T /Q /grant "%Group%":(OI)(CI)RXW ICACLS "%InstIdPath%\MSSQL" /T /Q /grant "%AgentGroup%":(OI)(CI)RX ICACLS "%InstIdPath%\MSSQL\binn" /T /Q /grant "%AgentGroup%":(OI)(CI)F ICACLS "%InstIdPath%\MSSQL\Log" /T /Q /grant "%AgentGroup%":(OI)(CI)F ICACLS "%Inst100Path%" /T /Q /grant "%AgentGroup%":(OI)(CI)RX endlocal

  • NoSQL Memcached API for MySQL: Latest Updates

    - by Mat Keep
    With data volumes exploding, it is vital to be able to ingest and query data at high speed. For this reason, MySQL has implemented NoSQL interfaces directly to the InnoDB and MySQL Cluster (NDB) storage engines, which bypass the SQL layer completely. Without SQL parsing and optimization, Key-Value data can be written directly to MySQL tables up to 9x faster, while maintaining ACID guarantees. In addition, users can continue to run complex queries with SQL across the same data set, providing real-time analytics to the business or anonymizing sensitive data before loading to big data platforms such as Hadoop, while still maintaining all of the advantages of their existing relational database infrastructure. This and more is discussed in the latest Guide to MySQL and NoSQL where you can learn more about using the APIs to scale new generations of web, cloud, mobile and social applications on the world's most widely deployed open source database The native Memcached API is part of the MySQL 5.6 Release Candidate, and is already available in the GA release of MySQL Cluster. By using the ubiquitous Memcached API for writing and reading data, developers can preserve their investments in Memcached infrastructure by re-using existing Memcached clients, while also eliminating the need for application changes. Speed, when combined with flexibility, is essential in the world of growing data volumes and variability. Complementing NoSQL access, support for on-line DDL (Data Definition Language) operations in MySQL 5.6 and MySQL Cluster enables DevOps teams to dynamically update their database schema to accommodate rapidly changing requirements, such as the need to capture additional data generated by their applications. These changes can be made without database downtime. Using the Memcached interface, developers do not need to define a schema at all when using MySQL Cluster. Lets look a little more closely at the Memcached implementations for both InnoDB and MySQL Cluster. Memcached Implementation for InnoDB The Memcached API for InnoDB is previewed as part of the MySQL 5.6 Release Candidate. As illustrated in the following figure, Memcached for InnoDB is implemented via a Memcached daemon plug-in to the mysqld process, with the Memcached protocol mapped to the native InnoDB API. Figure 1: Memcached API Implementation for InnoDB With the Memcached daemon running in the same process space, users get very low latency access to their data while also leveraging the scalability enhancements delivered with InnoDB and a simple deployment and management model. Multiple web / application servers can remotely access the Memcached / InnoDB server to get direct access to a shared data set. With simultaneous SQL access, users can maintain all the advanced functionality offered by InnoDB including support for Foreign Keys, XA transactions and complex JOIN operations. Benchmarks demonstrate that the NoSQL Memcached API for InnoDB delivers up to 9x higher performance than the SQL interface when inserting new key/value pairs, with a single low-end commodity server supporting nearly 70,000 Transactions per Second. Figure 2: Over 9x Faster INSERT Operations The delivered performance demonstrates MySQL with the native Memcached NoSQL interface is well suited for high-speed inserts with the added assurance of transactional guarantees. You can check out the latest Memcached / InnoDB developments and benchmarks here You can learn how to configure the Memcached API for InnoDB here Memcached Implementation for MySQL Cluster Memcached API support for MySQL Cluster was introduced with General Availability (GA) of the 7.2 release, and joins an extensive range of NoSQL interfaces that are already available for MySQL Cluster Like Memcached, MySQL Cluster provides a distributed hash table with in-memory performance. MySQL Cluster extends Memcached functionality by adding support for write-intensive workloads, a full relational model with ACID compliance (including persistence), rich query support, auto-sharding and 99.999% availability, with extensive management and monitoring capabilities. All writes are committed directly to MySQL Cluster, eliminating cache invalidation and the overhead of data consistency checking to ensure complete synchronization between the database and cache. Figure 3: Memcached API Implementation with MySQL Cluster Implementation is simple: 1. The application sends reads and writes to the Memcached process (using the standard Memcached API). 2. This invokes the Memcached Driver for NDB (which is part of the same process) 3. The NDB API is called, providing for very quick access to the data held in MySQL Cluster’s data nodes. The solution has been designed to be very flexible, allowing the application architect to find a configuration that best fits their needs. It is possible to co-locate the Memcached API in either the data nodes or application nodes, or alternatively within a dedicated Memcached layer. The benefit of this flexible approach to deployment is that users can configure behavior on a per-key-prefix basis (through tables in MySQL Cluster) and the application doesn’t have to care – it just uses the Memcached API and relies on the software to store data in the right place(s) and to keep everything synchronized. Using Memcached for Schema-less Data By default, every Key / Value is written to the same table with each Key / Value pair stored in a single row – thus allowing schema-less data storage. Alternatively, the developer can define a key-prefix so that each value is linked to a pre-defined column in a specific table. Of course if the application needs to access the same data through SQL then developers can map key prefixes to existing table columns, enabling Memcached access to schema-structured data already stored in MySQL Cluster. Conclusion Download the Guide to MySQL and NoSQL to learn more about NoSQL APIs and how you can use them to scale new generations of web, cloud, mobile and social applications on the world's most widely deployed open source database See how to build a social app with MySQL Cluster and the Memcached API from our on-demand webinar or take a look at the docs Don't hesitate to use the comments section below for any questions you may have

  • 426 Connection closed; transfer aborted.

    - by Jiaoziren
    Hi, I have an IIS FTP set up on Windows 2003 SP2 (S1). Everyday in the early morning, a script on another server (S2) will run and initiate FTP transfer of pulling log files from S1 to S2. The FTP client we're using is built-in FTP.exe in Windows 2000 on S2. Recently we replaced S1 with a new server however we kept the IP address. There are multiple IP addresses on new S1. Ever since the new S1 was in place, the '426 Connection closed; transfer aborted.' errors haven been occuring randomly. The log indicated that the transfer started ok however the file cannot be transferred completely, as per log below: mget access*.log 200 Type set to A. 200 PORT command successful. 150 Opening ASCII mode data connection for access02232010.log(205777167 bytes). 426 Connection closed; transfer aborted. ftp: 20454832 bytes received in 283.95Seconds 72.04Kbytes/sec. The firewall monitor suggested that the connection was setup in passive mode however I've been told that MS FTP.exe doesn't support passive mode. Though I can see the response of 'entering passive mode' from server when typing in 'quote pasv'. My network admin has told me to try the transfer in active mode however I don't know how to open active mode on client side. It's getting really frustrating. Wish someone here has the right knowledge/experience could shed me a light. Cheers.

  • Connecting to a remote server through OpenVPN when local network subnet conflicts with remote network's subnet

    - by John Russell
    After connecting to a remote location via OpenVPN, I am trying to access a server on a network that exists on a subnet such as 10.0.1.0/24. However, the network I am trying to access this remote server from is on the same subnet: 10.0.1.0/24. I am unable to connect to my remote server via typing in its IP because of this conflict. I am unable to even access the public internet while connected to the VPN. Does anyone know how to mitigate this issue? I have access to the OpenVPN Access Server.

  • SCCM Client Push FAIL - Win2000 box

    - by ajp
    Hello, When trying to install the SCCM client onto a Windows 2000 box, the install fails. The install script is run through a batch file (CONTENTS: \mdop\SCCM_client\ccmsetup.exe /mp:MDOP /logon smssitecode=MID smsslp=MDOP) hosted on a public area of the network. This script has worked for all machines (mostly Win2003 Server). I've tried enabling all the common services it requires (BITS, IIS Admin, Windows Installer), but it still only runs for a second or two then quits. Here's the piece of the log file where it errors out: [LOG[Couldn't get directory list for directory 'http://MDOP/CCM_Client/ClientPatch'. This directory may not exist.]LOG]! time="13:55:53.618+300" date="06-30-2009" component="ccmsetup" context="" type="0" thread="1676" file="ccmsetup.cpp:6054" Full Log: http://paste-it.net/public/gb11732/

  • Read-only file system

    - by John
    The title might not be as descriptive as I would like it to be but couldn't come up with a better one. My server's file system went into Read-only. And I don't understand why it does so and how to solve it. I can SSH into the server and when trying to start apache2 for example I get the following : username@srv1:~$ sudo service apache2 start [sudo] password for username: sudo: unable to open /var/lib/sudo/username/1: Read-only file system * Starting web server apache2 (30)Read-only file system: apache2: could not open error log file /var/log/apache2/error.log. Unable to open logs Action 'start' failed. The Apache error log may have more information. When I try restarting the server I get : username@srv1:~$ sudo shutdown -r now [sudo] password for username: sudo: unable to open /var/lib/sudo/username/1: Read-only file system Once I restart it manually it just start up without any warning or message saying something is wrong. I hope somebody could point me into the right direction to resolve this issue. Thanks in advance!

  • SCCM 2012 - some remote clients unable to download some applications, 401.2 error

    - by growse
    I've got a small SCCM 2012 deployment with about 35 clients attached. Most of these clients are in the same network as the single SCCM host, but three are about 1000 miles away. Oddly, these three clients have stopped being able to download some application packages over BITS. Publishing a new package works for all the other clients, but for these three it never seems to download. If I go to the software centre, it just hangs at "0% downloaded". On the client, the DataTransfer.log says (repeatedly): CDTSJob::HandleErrors: DTS Job '{2DCBBB4C-6D84-479A-9218-885B72C834B9}' BITS Job '{E78147DD-4A26-4942-B4FD-6EC3EB77EECD}' under user 'S-1-5-18' OldErrorCount 442 NewErrorCount 443 ErrorCode 0x80072EE2 DataTransferService 30/07/2012 09:27:41 2964 (0x0B94) CDTSJob::HandleErrors: DTS Job ID='{2DCBBB4C-6D84-479A-9218-885B72C834B9}' URL='http://sccm-host:80/SMS_DP_SMSPKG$/Content_3e7f6982-6346-4f27-ae00-ad5dcb391455.1' ProtType=1 DataTransferService 30/07/2012 09:27:41 2964 (0x0B94) Cas.log says (repeatedly): Location update from CTM for content Content_3e7f6982-6346-4f27-ae00-ad5dcb391455.1 and request {AD041FCB-03D2-4FE6-A6FA-38A6B80FB2A1} ContentAccess 30/07/2012 08:33:39 5048 (0x13B8) Download location found 0 - http://lonsbrndsccm02.mcs.int.thomsonreuters.com/SMS_DP_SMSPKG$/Content_3e7f6982-6346-4f27-ae00-ad5dcb391455.1 ContentAccess 30/07/2012 08:33:39 5048 (0x13B8) Download request only, ignoring location update ContentAccess 30/07/2012 08:33:39 5048 (0x13B8) On the server, I've enabled failed request log tracing.

The failed request log is large, but the punchline is that it chucks out a Unauthorized: Access is denied due to invalid credentials. message. All clients are members of the same domain and appear to be (otherwise) working great. I've re-installed the SCCM client, deleted and re-added the computer to SCCM. Some other packages seem to work fine, the daily anti-malware delta gets downloaded and patched without issue. Why are these packages failing?

  • Getting AWStats to work in Ubuntu 12.04

    - by koogee
    I'm new to apache and i'm trying to set up AWStats on my ubuntu 12.04 server. I've followed the guide at Ubuntu docs https://help.ubuntu.com/community/AWStats I set it up according to the instructions and awstats is able to generate initial stats from apache log successfully. I placed the links to awstats in the default virtual host file. However when I try to run http://server-ip-address:8080/awstats/awstats.pl, I get: Error: SiteDomain parameter not defined in your config/domain file. You must edit it for using this version of AWStats. Setup ('/etc/awstats/awstats.conf' file, web server or permissions) may be wrong. Check config file, permissions and AWStats documentation (in 'docs' directory). Here is my /etc/apache2/sites-available/default file: <VirtualHost *:8080> ServerAdmin webmaster@localhost DocumentRoot /home/saad/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /home/saad/www/> Options Indexes FollowSymLinks MultiViews AllowOverride AuthConfig Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> Alias /awstatsclasses "/usr/share/awstats/lib/" Alias /awstats-icon "/usr/share/awstats/icon/" Alias /awstatscss "/usr/share/doc/awstats/examples/css" ScriptAlias /awstats/ /usr/lib/cgi-bin/ Options ExecCGI -MultiViews +SymLinksIfOwnerMatch ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

  • Oracle 10g for Windows does not start up on system boot

    - by Mike Dimmick
    We have an Oracle 10g Enterprise Edition installation (10.2.0.1.0) on a Windows Server 2003 virtual machine. It was initially created with Virtual Server 2005 R2 SP1 but has now been migrated to Windows Server 2008 Hyper-V. The services start on system boot, but the instance does not start up. This problem was actually occurring on Virtual Server after a migration from one server to another, but I managed to fix it then with: oradim -edit -sid ORCL -startmode auto However, this now has no effect. oradim.log (in %OracleHome%\database\oradim.log) says: Thu Jun 10 14:14:48 2010 C:\oracle\product\10.2.0\db_3\bin\oradim.exe -startup -sid orcl -usrpwd * -log oradim.log -nocheck 0 Thu Jun 10 14:14:48 2010 ORA-12560: TNS:protocol adapter error sqlnet.log in the same folder has: Fatal NI connect error 12560, connecting to: (DESCRIPTION=(ADDRESS=(PROTOCOL=BEQ)(PROGRAM=oracle)(ARGV0=oracleorcl)(ARGS='(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))'))(CONNECT_DATA=(SID=orcl)(CID=(PROGRAM=C:\oracle\product\10.2.0\db_3\bin\oradim.exe)(HOST=ORACLE-VM)(USER=SYSTEM)))) VERSION INFORMATION: TNS for 32-bit Windows: Version 10.2.0.1.0 - Production Oracle Bequeath NT Protocol Adapter for 32-bit Windows: Version 10.2.0.1.0 - Production Time: 10-JUN-2010 14:14:48 Tracing not turned on.

The problem also occurs when stopping and restarting the OracleServiceORCL service. I've enabled SQL*Net tracing which shows: [10-JUN-2010 15:09:33.919] snlpcss: entry [10-JUN-2010 15:09:34.419] snlpcss: Unable to spawn Oracle oracle (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq))) orcl, error 2.

Right now I have a horrible hack where I've created a Scheduled Task to run oradim -startup -sid ORCL when the Administrator account logs on, and set the VM to auto-logon. I'd still like to work out why it's not working.

  • Save output and exit code of command to files on windows

    - by poncha
    I want to run a command and save its output and its exit code, in different files. Here's what i am doing: cmd.exe /C command 1> %TEMP%\output.log 2> %TEMP%\error.log && echo %ERRORLEVEL% > %TEMP%\status || echo %ERRORLEVEL% > %TEMP%\status If i don't do output redirection (into %TEMP%\output.log and/or %TEMP%\error.log), then exit code is saved just fine. However, when i run the line as shown above more than once (just get back to previous line in command prompt and rerun it), i get 0 in %TEMP%\status regardless of the real exit code. What am i missing? Or maybe there's a better way of doing this?

  • Snort/Barnyard2 Logging

    - by Eric
    I need some help with my Snort/Barnyard2 setup. My goal is to have Snort send unified2 logs to Barnyard2 and then have Barnyard2 send the data to other locations. Here is my currrent setup. OS Scientific Linux 6 Snort Version 2.9.2.3 Barnyard2 Version 2.1.9 Snort command snort -c /etc/snort/snort.conf -i eth2 & Barnyard2 command /usr/local/bin/barnyard2 -c /etc/snort/barnyard2.conf -d /var/log/snort -f snort.log -w /var/log/snort/barnyard.waldo & snort.conf output unified2: filename snort.log, limit 128 barnyard2.conf output alert_syslog: host=127.0.0.1 output database: log, mysql, user=snort dbname=snort password=password host=localhost With this setup, barnyard2 is showing all of the correct information in the database and I'm using BASE to view it on the web GUI. I was hoping to be able to send the full packet data to syslog with barnyard2 but after reading around, it seems that it is impossible to do that. So I then started trying to modify the snort.conf file and add lines like "output alert_full: alert.full". This definitely gave me a lot more information but still not the full packet data like I want. So my question is, is there anyway I can use barnyard2 to send the full packet data of alerts to a human readable file? Since I can't send it directly to syslog, I can create another process to take the data from that file and ship it off to another server. If not, what flags and/or snort.conf configuration would you recommend to get the most data possible but still be able to handle quite a bit of traffic? In the end of it all, these alerts will be shipped to a central server via a SSH tunnel. I'm trying to stay away from databases.

  • Permission issues causes Unity Segmentation fault

    - by Dj Gilcrease
    I upgraded from 13.04 to 13.10 and I can boot to the unity-greeter and login just fine, but after login I just get a black screen with a cursor. I have tried following http://help.ubuntu.com/community/BinaryDriverHowto/ATI http://help.ubuntu.com/community/RadeonDriver and the manual install of the downloaded AMD drivers. All have the same affect. Also I have read Black screen after login with cursor I get a black screen after logging in ubuntu 13.04 black screen after login Ubuntu 13.10 - Black screen after login session Ubuntu 13.04 - Black screen with unresponsive cursor Upgrade to Ubuntu 13.04 Problem - Boots into Blank Black Screen All of which were no further help then the two support articles about ATI drivers So I switched back to the default drivers and went a little further into debugging, when I do ctrl+alt+F1 and login and try unity --debug > unity_start.log then ctrl+alt+F8 the screen stays black with a cursor and when I switch back ctrl+alt+F1 the contents of the log output are http://pastebin.com/rdQG4Hb0 However when I try sudo unity --debug > unity_start_root.log then ctrl+alt+F8, unity starts and the output of the log is http://pastebin.com/Yv4RD2j7 The fact that it starts as root tells be it is either a permissions issue of some required file or there is some setting that is specific to my user that is causing the SIGSEGV. So to narrow this down I activated the guest account and tried to login and got the same black screens with only a mouse cursor, so this tells me that it is not a configuration issue, but a permissions issue, so how do I narrow down which file has the wrong permissions? Also is there anything further that may help debug this issue? Ok after a few more hours of googling I found that if I add myself to the video group I can login and see the desktop, but there are lots of other permission related issues, so I am thinking something went wonky with PolicyKit during the upgrade, is there a way to reset PolicyKit settings for a user?

  • BIP Debugging to a file

    - by Tim Dexter
    If you use the standalone server or with OBIEE and use OC4J as the web server. Have you ever taken a looksee at the console window (doc/xterm) that you use to start it. Ever turned on debugging to see masses of info flow by that window and want to capture it all? I have been debugging today and watched all that info fly by and on Windoze gets lost before you can see it! The BIP developers use the System.out.println() and System.err.println()methods in the BIP applications to generate debugging formation. Normally the output from these method calls go to the console where the OC4J process is started. However you can specify command line options when starting OC4J to direct the stdout and stderr output directly to files. The ?out and ?err parameters tell OC4J which file to direct the output to. All you need do is modify the oc4j.cmd file used to start BIP. I didnt get fancy and just plugged in the following to the file under the start section. I just modified the line: set CMDARGS=-config "%SERVER_XML%" -userThreads to set CMDARGS=-config "%SERVER_XML%" -out D:\BI\OracleBI\oc4j_bi\j2ee\home\log\oc4j.out -err D:\BI\OracleBI\oc4j_bi\j2ee\home\log\oc4j.err -userThreads Bounced the server and I now have a ballooning pair of debug files that I can pour over to my hearts content. The .out file appears to contain BIP only log info and the .err file, OBIEE messages. If you are using another web server to host BIP, just check out the user docs to find out how to get the log files to write. Note to self, remember to turn off the debug when Im done!

  • How to create a very simple external FastCGI configuration in apache?

    - by Thiado de Arruda
    I have an externally started FastCGI application that listens on socket '/tmp/foo.sock' and a directory of static files in '/srv/static'. Apache has all needed permissions on the socket and the directories. What I need : All requests starting with '/static' should be handled by apache using the contents of '/srv/static'. All other requests should be handled by the FastCGI application. Here is my current virtual host configuration: <VirtualHost *:80> ServerAdmin [email protected] ServerName www.foo.com ServerAlias foo.com Alias /static /srv/static FastCgiExternalServer /* -socket /tmp/foo.sock ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog /var/log/apache2/access.log combined </VirtualHost> Even though this seems simple, its giving me quite the headache. According to http://www.fastcgi.com/mod_fastcgi/docs/mod_fastcgi.html#FastCgiExternalServer the first parameter to 'FastCgiExternalServer' should be a 'filename' that when matched will cause apache to delegate the request to the external FastCGI app. What am I missing here?
