  • CentOS 5 VPN Server won't work

    - by Miro Markarian
    I have a CentOS 5 server configured to be both a L2TP server and a PPTP server + a radius server for hosting the AAA. My problem is that, the L2TP works great and I can connect to it, but can't connect to PPTP and every-time it ends up with error #619 when it gets to the verifying username and password section. Here is the log I got from /var/log/messages Dec 17 07:40:02 serverdl pptpd[8570]: CTRL: Client 5.52.247.62 control connection started Dec 17 07:40:03 serverdl pptpd[8570]: CTRL: Starting call (launching pppd, opening GRE) Dec 17 07:40:03 serverdl pppd[8571]: Plugin radius.so loaded.

Dec 17 07:40:03 serverdl pptpd[8570]: CTRL: Client 5.52.247.62 control connection finished Just yesterday when I hadn't set up the L2TP yet PPTP was working great but then I uninstalled it and removed all it's config from /etc/* and installed L2TP first and then installed PPTP after it. and then it stopped to work. I believe it must be a radiusclient issue because both of the PPTP and L2TP services use radius to authenticate. And another thing I think must be the issue is that when assigning IPs to the PPP interfaces, I have done the following config. Is that right? For L2TP: localip 10.10.10.1 remoteip 10.10.10.2-254 For PPTP: localip 10.10.9.1 remoteip 10.10.9.2-254

  • Migrating to Windows Server 2008 R2 Domain Controllers - a few Questions/Issues

    - by Chris
    Ok so here's our setup: We have 2 Windows 2003 Domain Controllers. I am trying to replace them with Windows 2008 R2. The 2003 servers are named DC01 and DC02. The 2008 R2 servers are DC1 and DC2. I prepared the Windows Server 2003 Forest Schema for a Domain Controller that runs Windows Server 2008 or Windows Server 2008 R2. Then with both of the new servers up as member servers I ran dcpromo on DC1 using the advanced option and added it successfully to my existing domain. It's roles are GC, DNS and Active Directory Domain Services. I transferred The PDC Emulator, RID Pool Manager, and Infrastructure Master roles to DC1. The Schema Master and Domain Naming master are still on DC01. The first issue that I'm encountering is when I dcpromo the DC2 and select "Replicate data over the network from and existing domain controller" I select that I want to replicate from DC1 and I get the following error: Failed to identify the requested replica partner (dc1.xxx.org) as a valid domain controller with a machine account for (DC2$). This is likely due to either the machine account not being replicated to this domain controller because of replication latency or the domain controller not advertising the Active Directory Domain Services. Please consider retrying the operation with \dc01.xxx.org as the replica partner. "The server is unwilling to process the request. Is this because the Schema Master and Domain Naming Master roles are still on the old DC01? And if so, if I transfer Schema Master and Domain Naming Master roles to DC1 what is the risk or breaking my AD? I'm a little paranoid because this process HAS to be transparent. ANY down time or interruption will result in me getting a verbal ass kicking from my I.T. Director. Both of the new servers DNS point the the old DNS servers (DC01 and DC02) not themselves by the way.

  • Should integration testing of DAOs be done in an application server?

    - by HDave
    I have a three tier application under development and am creating integration tests for DAOs in the persistence layer. When the application runs in Websphere or JBoss I expect to use the connection pooling and transaction manager of those application servers. When the application runs in Tomcat or Jetty, we'll be using C3P0 for pooling and Atomikos for transactions. Because of these different subsystems, should the DAO's be tested in a fully configured application server environment or should we handle those concerns when integration testing the service layer? Currently we plan on setting up a simple JDBC data source with non-JTA (i.e. resource-local) transactions for DAO integration testing, thus no application server is involved....but this leaves me wondering about environmental problems we won't uncover.

  • Why is sql server giving a conversion error when submitting date.today to a datetime column?

    - by kpierce8
    I am getting a conversion error every time I try to submit a date value to sql server. The column in sql server is a datetime and in vb I'm using Date.today to pass to my parameterized query. I keep getting a sql exception Conversion failed when converting datetime from character string. Here's the code Public Sub ResetOrder(ByVal connectionString As String) Dim strSQL As String Dim cn As New SqlConnection(connectionString) cn.Open() strSQL = "DELETE Tasks WHERE ProjID = @ProjectID" Dim cmd As New SqlCommand(strSQL, cn) cmd.Parameters.AddWithValue("ProjectID", 5) cmd.ExecuteNonQuery() strSQL = "INSERT INTO Tasks (ProjID, DueDate, TaskName) VALUES " & _ " (@ProjID, @TaskName, @DueDate)" Dim cmd2 As New SqlCommand(strSQL, cn) cmd2.CommandText = strSQL cmd2.Parameters.AddWithValue("ProjID", 5) cmd2.Parameters.AddWithValue("DueDate", Date.Today) cmd2.Parameters.AddWithValue("TaskName", "bob") cmd2.ExecuteNonQuery() cn.Close() DataGridView1.DataSource = ds.Projects DataGridView2.DataSource = ds.Tasks End Sub Any thoughts would be greatly appreciated.

  • Server not accepting uploads

    - by Tatu Ulmanen
    I'm having a strange problem with my VPS: I can download files from it, I can use PuTTy to connect to it and all behaves normally. But sometimes, when I try to upload a file to the server or save a file via SFTP, the connection inexplicably fails. I am using jEdit to edit files remotely via SFTP. When it works, it works fine. When it doesn't, I get an error message: Cannot save: java.io.IOException: inputstream is closed Cannot save: java.io.IOException: 4: I can see that a temporary save file (#file.php#save#) is created on the server with a filesize of 0. So the connection works, but when it comes to sending the actual data, something fails. The same thing with WinSCP, but the error is different: Copying file fatally failed. Copying files to remote side failed. And I can always browse the server with PuTTy without a problem. I see nothing abnormal in any log files. Auth.log shows this when I try to save: sshd[32638]: Accepted password for - from - port 62272 ssh2 sshd[32638]: pam_unix(sshd:session): session opened for user - by (uid=0) sshd[32640]: subsystem request for sftp sshd[32638]: pam_unix(sshd:session): session closed for user - When I wait for a while (say, an hour), everything works fine again. It can't be a temporary ban, as I am still allowed to connect to the server, right? I know this may not be enough info to solve the problem, but I am grateful for any clues or bits of information that might help me. What are the possible causes for this kind of behaviour, what log files can I check for clues etc.. I'm running out of ideas!

  • Is it possible to partition more than one way at a time in SQL Server?

    - by meeting_overload
    I'm considering various ways to partition my data in SQL Server. One approach I'm looking at is to partition a particular huge table into 8 partitions, then within each of these partitions to partition on a different partition column. Is this even possible in SQL Server, or am I limited to definining one parition column+function+scheme per table? I'm interested in the more general answer, but this strategy is one I'm considering for Distributed Partitioned View, where I'd partition the data under the first scheme using DPV to distribute the huge amount of data over 8 machines, and then on each machine partition that portion of the full table on another parition key in order to be able to drop (for example) sub-paritions as required.

  • Is there a SQL Server error numbers C# wrapper anyone knows of?

    - by Mr Grok
    I really want to do something useful when a PK violation occurs but I hate trapping error numbers... they just don't read right without comments (they're certainly not self documenting). I know I can find all the potential error numbers at SQL Server books online but I really want to be able to pass the error number to some helper class or look it up against a Dictionary of some sort rather than have non-descript err numbers everywhere. Has anyone got / seen any code anywhere that encapsulates the SQL Server Error numbers in this way as I don't want to re-invent the wheel (or I'm lazy maybe).

  • How do I create queries to SQL Server tables via Visual Studio when no knowledge about SQL nor Linq?

    - by Kent S. Clarkson
    Let´s be frank, my knowledge regarding SQL language is very low. Nevertheless, my boss gave me the task to build a database application using the following tools: SQL Server and Visual Studio 2008; C#. I use the VS DataSet as a local mirror of the SQL Server. And let´s be frank again, my understanding of the VS Query builder is also very small, I´m finding it quite confusing, actually. So no help to find from Query builder. And my knowledge of Linq is even lower... Perhaps I should mention that the deadline for the project is "aggressively" set, so I have no chance to learn enough about these things during the project. And I´m a bit stupid too, which is no help when it comes to challenges like this (on other occations it might be quite useful though) With these permissions, what should I do (except for killing myself or retire) to be able to query my tables in a sufficient way?

  • MySQL slave server from dumps

    - by HTF
    I've created a slave server from live machine which is acting as a master now. I use the following procedure to create it: mysqldump --opt -Q -B --master-data=2 --all-databases > dump.sql then I imported this dump on the new machine, applied the "CHANGE MASTER TO..." directive with a log file/position from the dump. Please note that I have around 8000 databases and I didn't stop the master while the dumps were running. The replication works fine but is this a properly method for creating a slave server? I'm planning to promote this slave to a master (different location) so I would like to make sure that there is a 100% data consistency between the servers. I've found this article where it says: The naive approach is just to use mysqldump to export a copy of the master and load it on the slave server. This works if you only have one database. With multiple database, you'll end up with inconsistent data. Mysqldump will dump data from each database on the server in a different transaction. That means that your export will have data from a different point in time for each database. Thank you

  • Getting prompted for password accessing page through script even when client and server are in same

    - by Munawar
    I'm trying to pull up an internal webpage in automated fashion using the methods in 'Internetexplorer.Application' using vbscript. But I'm getting prompted for password, although the client and the server both are in the same domain. Predictably when I manually try to access the web page, I don't have any problem. Only when I try using cscript.exe or iexplore.exe, I get prompted. I'm trying to automate some of the smoke test we do after a new build is deployed. But this password prompt is getting in the way. Following are the system specs Client machine - IE 7.0, OS is Windows server 2003 Server machine - Windows Server 2008 Both are in the same domain. So far I've unsuccessfully tried following to automate the password input system.diagnostics.process.start var WinHttpReq = new ActiveXObject("WinHttp.WinHttpRequest.5.1"); WinHttpReq.Open("GET", "http://website", false); WinHttpReq.SetCredentials("username", "password", 0); Nothing seems to work I checked in IIS. we have only anonymous and forms authentication enabled Is there any configuration setting in the client machine that can be tweaked to bypass this, although I'd hate to do it since you step on the toes of twenty people trying to do that. Preferable way would be to programmatically input it if its possible. Also, if you can suggest a more appropriate forum, that'd be great too. Please help.

  • Shared configuration for Eclipse on Debian server

    - by Joris Meys
    I've manually installed the latest Eclipse on our debian server and wanted to configure it so all users share the same configuration. It turned out less obvious than I thought: I don't seem to be able to install packages for all users. If I run it myself, all configuration data is saved under my own home directory. If I run Eclipse using sudo, everything is saved under the root directory but is not accessible for other users when they run Eclipse. I've been browsing the manual of Eclipse and some forums, but apart from a "yes, you can" I couldn't find any information on how that should be done. The biggest problem is installing plugins for all users to be found. Any help is greatly appreciated. Eclipse : 3.6.1 classic, installed using this procedure. Server uname: GNU/Linux * 2.6.26-2-amd64 Server is accessed using Putty, and Gnome desktop through realVNC. Just mentioning it if that is of any importance. Our sysadmin is on "prolonged leave" (working in Spain and never replaced), so I'm stuck without help here. EDIT : -- I asked this question also on StackOverflow as I wasn't certain this is a genuine server-related question. Please feel free to merge both questions at the appropriate place. --

  • Besides EAR and EJB, what do I get from a J2EE app server that I don't get in a servlet container li

    - by dacracot
    We use Tomcat to host our WAR based applications. We are servlet container compliant J2EE applications with the exception of org.apache.catalina.authenticator.SingleSignOn. We are being asked to move to a commercial J2EE application server. The first downside to changing that I see is the cost. No matter what the charges for the application server, Tomcat is free. Second is the complexity. We don't use either EJB nor EAR features (of course not, we can't), and have not missed them. What then are the benefits I'm not seeing? What are the drawbacks that I haven't mentioned? Mentioned were... JTA - Java Transaction API - We control transaction via database stored procedures. JPA - Java Persistence API - We use JDBC and again stored procedures to persist. JMS - Java Message Service - We use XML over HTTP for messaging. This is good, please more!

  • SSL connection error for only one site (of many) on server

    - by Matt Lacey
    I have a server running many websites, each with SSL. One of the sites is now refusing connections over SSL. This was previously working and I'm looking for assistance in determining what has been changed. Here's the situation: http://site1.com/ - works https://site1.com/ - works http://site2.com/ - works https://site2.com/ - Doesn't work (but did previously) Both sites are on the same server (Win Server 2003 SP2 - IIS6) Both sites use certificates from the same authority and are both valid (according to IIS). As far as I can tell, both sites have certificates configured identically in IIS. (Checked by a manual/visual check of properties, side by side) Through use of OpenSSL I can see that there's a "ssl handshake failure" when trying to connect to site2 using https. What could be the cause of this? How can I investigate further? Without SSL connections being available to this site, users are unable to log in or register. :( disclaimer: I'm not a server admin and not responsible for the box. Yes, there are wider issues here but I need to get this working again first.

  • End User Ad-Hoc Reporting Tool: Microsoft SQL Server Management Studio or Microsoft Access?

    - by schultkl
    Our centralized IT department has suggested two primary ad hoc query tools for our general user base of approximately 200 staff members: Microsoft SQL Server Management Studio 2008 (SSMS) Microsoft Access 2003 Environment The backend database is a read-only Microsoft SQL Server 2005 database. The schema is 400+ tables; allowing access to the raw data for our general staff would be a disaster. We will be building an "abstraction layer" over the raw data for our general staff to run ad hoc queries against. The abstraction layer will most likely contain a number of views. A number of users have basic knowledge in Microsoft Access; none have used SSMS. Which of the above tools (or alternative) would be best for a decidedly non-techie user base of approximately 200 people? What are the pros and cons of each? Also, the IT department has suggested teaching people T-SQL so they may use SSMS. Is this reasonable?

  • Server configration for our website [duplicate]

    - by Varun Varunesh
    This question already has an answer here: Can you help me with my capacity planning? 2 answers We are a start-up and 6 month back we have launched our beta version website. Now we are in a phase of building our website and web-services for the final product. This website will be based on PHP, Python, MySql database and with wamp server. Right now in the beta version we are using Azure VM for hosting, with configuration of 786MB RAM and Shared CPU. We have 200 avg users daily coming to our website. Now we are trying to increase the number of users from 200 to 1500 daily users. And I am thinking our server should have capability to handle at least 100 concurrent user. Also we have developed web-services for our mobile-apps. Which can also increase loads on the sever. So here are the question that takes me here, I am pretty much confused about whether to go with shared hosting or VM based hosting. If VM, then what configuration will be best for our requirement (as I discussed above) ? Currently our VM is a Windows based server and its very simple to manage, So other than cost factor why should I go for Linux based sever? What other factor should I keep in mind while choosing the server as per our requirement ?

  • Manual NAT on Checkpoint (Redirect all http requests to a local web server)

    - by B. Kulakli
    We have a proxy server in our internal network and I want to redirect all internet http requests to a web server in local network. It'll be like a Network Billboard that says "No direct connection is available. Set up your proxy etc." For example: A user starts the computer Opens the browser Tries to open www.google.com Should see web server output on local network Tries another web site on internet Should see web server output on local network Sets up proxy Tries to connect to a web site Web site should be loaded I have added a simple manual NAT rule to address translation in Checkpoint firewall but it simply does not work. Here is my address translation rule Source Destination Service T.Source T.Destination T.Service MY_PC A_GOOGLE_IP ALL ORIGINAL INT_WEB_SRV ORIGINAL Then when I ping A_GOOGLE_IP, replies come from INT_WEB_SRV, as I expected. However, when I try to connect A_GOOGLE_IP from browser (http://A_GOOGLE_IP), no replies come from SYN_SENT and falls into timeout. When I look at the firewall log of INT_WEB_SRV, I can see the incoming connection requests from MY_PC is accepted and NO denies. By the way, there is no problem to see INT_WEB_SRV (http://INT_WEB_SRV) from browser. My understanding is, my NAT rule at checkpoint NGX R60 does not include return packets. I definitely need some help.

  • Poor write performance on Debian server running NFS with 22TB exported JFS filesystem

    - by user143546
    I am currently running a debian server that is exporting a large JFS filesystem (22TB) over NFS (nfs-kernel-server.) When attempting to write to the NFS share, the performance is very poor. The 22TB disk is sitting on a NAS mounted using iSCSI. It will bust for a moment near expected line speed, and then sit idle for several seconds. Very little traffic measured in the low kb/sec. The wait peeks on write. When reading from the NFS mount, the system operates at expected speeds (11MB/sec). The issue does not occur when using SFTP, rsync, or local coping (non-nfs). The issue persists between stable and testing releases. On the same machine I have a 14TB ext4 filesystem using the exact same export configuration that does not share the issue. This share is not in regular use and thus not consuming resources. NFS Server: cat /etc/exports /data2 10.1.20.86(rw,no_subtree_check,async,all_squash) cat /sys/block/sdb/queue/scheduler noop [deadline] cfq cat /etc/default/nfs-kernel-server RPCNFSDCOUNT=8 RPCNFSDPRIORITY=0 RPCMOUNTDOPTS=--manage-gids NEED_SVCGSSD= RPCSVCGSSDOPTS= NFS Client: cat /etc/fstab 10.1.20.100:/data2 /root/incoming nfs rw,noatime,soft,intr,noacl 0 2 cat /sys/block/sdb/queue/scheduler noop [deadline] cfq cat /proc/mounts 10.1.20.100:/data2/ /root/incoming nfs4 rw,noatime,vers=4,rsize=262144,wsize=262144,namlen=255,soft,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.1.20.86,minorversion=0,addr=10.1.20.100 0 0 This problem has me pretty stumped.

  • Internet Explorer ignoring PHP setcookie() from CentOS server

    - by Hussein Sabbagh
    In the past we used a windows XAMPP server for an internal website. It worked fine but had some intermittent issues and we decided to move to a LAMP server on CentOS. We made the switch today but it turns out Internet Explorer ignores every attempt I make at saving a cookie. There is no underscore in the URL being used... the URL is actually the same as the one the XAMPP server used, where I was able to save cookies without any problems. It really doesn't make any sense to me, all of the code is the same. The only thing to change is the version of PHP and the server OS. The website works on all other browsers except IE. I can't even make a simple setcookie call. On a blank test page I use setcookie("test", "test", time()+36000, "/"); sleep(5); print_r($_COOKIE); and there is nothing there. Our users can't log into the website because of this and I have no idea what the issue is. If anyone can provide any clues or resolutions I would greatly appreciate it. Obviously the easy answer is to not use IE, but that is not an option in this case.

  • Local sites not displaying in VirtualBox when using Django's local development server?

    - by littlejim84
    Hello. I develop web applications using Django on Mac OSX 10.6. I use Django's built in local development server which I run on my computer's IP (such as: http://192.168.0.11:8001/). I test my applications in Firefox, Safari and Chrome and all display fine. I use Sun's VirtualBox with 3 different instances of Windows XP that have IE6, IE7 and IE8 on them. For whatever reason, these sometimes just don't display the Django sites. They come up with 'The page cannot be displayed'. Eight times out of ten, they display fine and function normally but for no reason at all they won't display. Sometimes restarting Django's local development server from the Terminal will fix the problem, sometimes it won't. Is there some sort of VirtualBox settings or Django settings that I need to set to ensure smooth operation of this? Am I overlooking something? Has anyone else had these problems?

  • PhpMyAdmin 500 Internal Server Error on Nginx/php5-fpm/Debian

    - by ThrownAway
    I downloaded PhpMyAdmin a while ago and am having a hard time getting it to work. Requesting localhost/phpmyadmin gives a 500 Internal Server Error response, but there's nothing in the error log. These are the steps I did: Downloaded the newest phpmyadmin and unzipped all the files to /var/vhosts/phpmyadmin/www/ Created a new php5-fpm pool and a server block on nginx Changed the owner of all the files inside phpmyadmin/ Tried requesting localhost/phpmyadmin and localhost/phpmyadmin/setup The phpmyadmin is running inside a chroot, and all the files are owned by www-data so it shouldn't be a permission error. I made a new php file in the same directory to produce an error and it logs just fine so it has to be just phpmyadmin. Here's my php5-fpm pool: [phpmyadmin] listen = /var/vhosts/phpmyadmin/tmp/.php.sock; user = www-data group = www-data chroot = /var/vhosts/phpmyadmin/ chdir = / php_admin_value[error_reporting] = E_ALL php_admin_value[error_log] = error.log php_admin_flag[log_errors] = on php_admin_flag[display_errors] = on php_value[session.save_handler] = files php_value[session.save_path] = /tmp And Nginx server block: server { listen 80; root /var/vhosts/phpmyadmin/www; server_name pma.domain; location / { try_files $uri $uri/ /index.html; autoindex on; } location ~ \.php$ { fastcgi_split_path_info ^(.+\.php)(/.+)$; include fastcgi_params; fastcgi_pass unix:/var/vhosts/phpmyadmin/tmp/.php.sock; fastcgi_param SCRIPT_FILENAME /www$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_param DOCUMENT_ROOT /www; } index index.html index.htm index.php; try_files $uri $uri/ =404; } Any ideas what could be wrong? Why is it not producing any errors even though I've forced them to be on?
