  • Dynamic Paging and Sorting

    - by Ricardo Peres
    Since .NET 3.5 brought us LINQ and expressions, I became a great fan of these technologies. There are times, however, when strong typing cannot be used - for example, when you are developing an ObjectDataSource and you need to do paging having just a column name, a page index and a page size, so I set out to fix this. Yes, I know about Dynamic LINQ, and even talked on it previously, but there's no need to add this extra assembly. So, without further delay, here's the code, in both generic and non-generic versions: public static IList ApplyPagingAndSorting(IEnumerable enumerable, Type elementType, Int32 pageSize, Int32 pageIndex, params String [] orderByColumns) { MethodInfo asQueryableMethod = typeof(Queryable).GetMethods(BindingFlags.Static | BindingFlags.Public).Where(m = (m.Name == "AsQueryable") && (m.ContainsGenericParameters == false)).Single(); IQueryable query = (enumerable is IQueryable) ? (enumerable as IQueryable) : asQueryableMethod.Invoke(null, new Object [] { enumerable }) as IQueryable; if ((orderByColumns != null) && (orderByColumns.Length 0)) { PropertyInfo orderByProperty = elementType.GetProperty(orderByColumns [ 0 ]); MemberExpression member = Expression.MakeMemberAccess(Expression.Parameter(elementType, "n"), orderByProperty); LambdaExpression orderBy = Expression.Lambda(member, member.Expression as ParameterExpression); MethodInfo orderByMethod = typeof(Queryable).GetMethods(BindingFlags.Public | BindingFlags.Static).Where(m = m.Name == "OrderBy").ToArray() [ 0 ].MakeGenericMethod(elementType, orderByProperty.PropertyType); query = orderByMethod.Invoke(null, new Object [] { query, orderBy }) as IQueryable; if (orderByColumns.Length 1) { MethodInfo thenByMethod = typeof(Queryable).GetMethods(BindingFlags.Public | BindingFlags.Static).Where(m = m.Name == "ThenBy").ToArray() [ 0 ].MakeGenericMethod(elementType, orderByProperty.PropertyType); PropertyInfo thenByProperty = null; MemberExpression thenByMember = null; LambdaExpression thenBy = null; for (Int32 i = 1; i 0) { MethodInfo takeMethod = typeof(Queryable).GetMethod("Take", BindingFlags.Public | BindingFlags.Static).MakeGenericMethod(elementType); MethodInfo skipMethod = typeof(Queryable).GetMethod("Skip", BindingFlags.Public | BindingFlags.Static).MakeGenericMethod(elementType); query = skipMethod.Invoke(null, new Object [] { query, pageSize * pageIndex }) as IQueryable; query = takeMethod.Invoke(null, new Object [] { query, pageSize }) as IQueryable; } MethodInfo toListMethod = typeof(Enumerable).GetMethod("ToList", BindingFlags.Static | BindingFlags.Public).MakeGenericMethod(elementType); IList list = toListMethod.Invoke(null, new Object [] { query }) as IList; return (list); } public static List ApplyPagingAndSorting(IEnumerable enumerable, Int32 pageSize, Int32 pageIndex, params String [] orderByColumns) { return (ApplyPagingAndSorting(enumerable, typeof(T), pageSize, pageIndex, orderByColumns) as List); } List list = new List { new DateTime(2010, 1, 1), new DateTime(1999, 1, 12), new DateTime(1900, 10, 10), new DateTime(1900, 2, 20), new DateTime(2012, 5, 5), new DateTime(2012, 1, 20) }; List sortedList = ApplyPagingAndSorting(list, 3, 0, "Year", "Month", "Day"); SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/2.0.320/scripts/clipboard.swf'; SyntaxHighlighter.brushes.CSharp.aliases = ['c#', 'c-sharp', 'csharp']; SyntaxHighlighter.all();

  • Virtual host is not working in Ubuntu 14 VPS using XAMPP 1.8.3

    - by viral4ever
    I am using XAMPP as server in ubuntu 14.04 VPS of digitalocean. I tried to setup virtual hosts. But it is not working and I am getting 403 error of access denied. I changed files too. My files with changes are /opt/lampp/etc/httpd.conf # # This is the main Apache HTTP server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs/trunk/> for detailed information. # In particular, see # <URL:http://httpd.apache.org/docs/trunk/mod/directives.html> # for a discussion of each configuration directive. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so 'log/access_log' # with ServerRoot set to '/www' will be interpreted by the # server as '/www/log/access_log', where as '/log/access_log' will be # interpreted as '/log/access_log'. # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # Do not add a slash at the end of the directory path. If you point # ServerRoot at a non-local disk, be sure to specify a local disk on the # Mutex directive, if file-based mutexes are used. If you wish to share the # same ServerRoot for multiple httpd daemons, you will need to change at # least PidFile. # ServerRoot "/opt/lampp" # # Mutex: Allows you to set the mutex mechanism and mutex file directory # for individual mutexes, or change the global defaults # # Uncomment and change the directory if mutexes are file-based and the default # mutex file directory is not on a local disk or is not appropriate for some # other reason. # # Mutex default:logs # # Listen: Allows you to bind Apache to specific IP addresses and/or # ports, instead of the default. See also the <VirtualHost> # directive. # # Change this to Listen on specific IP addresses as shown below to # prevent Apache from glomming onto all bound IP addresses. # #Listen 12.34.56.78:80 Listen

  • Running Apache and Tomcat together on different subdomains?

    - by Ritesh M Nayak
    Posted this on ServerFault but didn't get a response. Hoping I will have better luck on the Ubuntu site. I have been trying to get this working the whole of today. I have a server which resolves to the domain example.com . This is running Apache2 and Tomcat 6. The requirement is to direct requests to example.com to apache2 and app.example.com to Tomcat.

  • Dynamic Filtering

    - by Ricardo Peres
    Continuing my previous posts on dynamic LINQ, now it's time for dynamic filtering. For now, I'll focus on string matching. There are three standard operators for string matching, which both NHibernate, Entity Framework and LINQ to SQL recognize: Equals Contains StartsWith EndsWith So, if we want to apply filtering by one of these operators on a string property, we can use this code: public enum MatchType { StartsWith = 0, EndsWith = 1, Contains = 2, Equals = 3 } public static List Filter(IEnumerable enumerable, String propertyName, String filter, MatchType matchType) { return (Filter(enumerable, typeof(T), propertyName, filter, matchType) as List); } public static IList Filter(IEnumerable enumerable, Type elementType, String propertyName, String filter, MatchType matchType) { MethodInfo asQueryableMethod = typeof(Queryable).GetMethods(BindingFlags.Static | BindingFlags.Public).Where(m = (m.Name == "AsQueryable") && (m.ContainsGenericParameters == false)).Single(); IQueryable query = (enumerable is IQueryable) ? (enumerable as IQueryable) : asQueryableMethod.Invoke(null, new Object [] { enumerable }) as IQueryable; MethodInfo whereMethod = typeof(Queryable).GetMethods(BindingFlags.Public | BindingFlags.Static).Where(m = m.Name == "Where").ToArray() [ 0 ].MakeGenericMethod(elementType); MethodInfo matchMethod = typeof(String).GetMethod ( (matchType == MatchType.StartsWith) ? "StartsWith" : (matchType == MatchType.EndsWith) ? "EndsWith" : (matchType == MatchType.Contains) ? "Contains" : "Equals", new Type [] { typeof(String) } ); PropertyInfo displayProperty = elementType.GetProperty(propertyName, BindingFlags.Public | BindingFlags.Instance); MemberExpression member = Expression.MakeMemberAccess(Expression.Parameter(elementType, "n"), displayProperty); MethodCallExpression call = Expression.Call(member, matchMethod, Expression.Constant(filter)); LambdaExpression where = Expression.Lambda(call, member.Expression as ParameterExpression); query = whereMethod.Invoke(null, new Object [] { query, where }) as IQueryable; MethodInfo toListMethod = typeof(Enumerable).GetMethod("ToList", BindingFlags.Static | BindingFlags.Public).MakeGenericMethod(elementType); IList list = toListMethod.Invoke(null, new Object [] { query }) as IList; return (list); } var list = new [] { new { A = "aa" }, new { A = "aabb" }, new { A = "ccaa" }, new { A = "ddaadd" } }; var contains = Filter(list, "A", "aa", MatchType.Contains); var endsWith = Filter(list, "A", "aa", MatchType.EndsWith); var startsWith = Filter(list, "A", "aa", MatchType.StartsWith); var equals = Filter(list, "A", "aa", MatchType.Equals); Perhaps I'll write some more posts on this subject in the near future.

  • Lesser Known NHibernate Session Methods

    - by Ricardo Peres
    The NHibernate ISession, the core of NHibernate usage, has some methods which are quite misunderstood and underused, to name a few, Merge, Persist, Replicate and SaveOrUpdateCopy. Their purpose is: Merge: copies properties from a transient entity to an eventually loaded entity with the same id in the first level cache; if there is no loaded entity with the same id, one will be loaded and placed in the first level cache first; if using version, the transient entity must have the same version as in the database; Persist: similar to Save or SaveOrUpdate, attaches a maybe new entity to the session, but does not generate an INSERT or UPDATE immediately and thus the entity does not get a database-generated id, it will only get it at flush time; Replicate: copies an instance from one session to another session, perhaps from a different session factory; SaveOrUpdateCopy: attaches a transient entity to the session and tries to save it. Here are some samples of its use. ISession session = ...; AuthorDetails existingDetails = session.Get<AuthorDetails>(1); //loads an entity and places it in the first level cache AuthorDetails detachedDetails = new AuthorDetails { ID = existingDetails.ID, Name = "Changed Name" }; //a detached entity with the same ID as the existing one Object mergedDetails = session.Merge(detachedDetails); //merges the Name property from the detached entity into the existing one; the detached entity does not get attached session.Flush(); //saves the existingDetails entity, since it is now dirty, due to the change in the Name property AuthorDetails details = ...; ISession session = ...; session.Persist(details); //details.ID is still 0 session.Flush(); //saves the details entity now and fetches its id ISessionFactory factory1 = ...; ISessionFactory factory2 = ...; ISession session1 = factory1.OpenSession(); ISession session2 = factory2.OpenSession(); AuthorDetails existingDetails = session1.Get<AuthorDetails>(1); //loads an entity session2.Replicate(existingDetails, ReplicationMode.Overwrite); //saves it into another session, overwriting any possibly existing one with the same id; other options are Ignore, where any existing record with the same id is left untouched, Exception, where an exception is thrown if there is a record with the same id and LatestVersion, where the latest version wins SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/2.0.320/scripts/clipboard.swf'; SyntaxHighlighter.brushes.CSharp.aliases = ['c#', 'c-sharp', 'csharp']; SyntaxHighlighter.all();

  • Failing report subscriptions

    - by DavidWimbush
    We had an interesting problem while I was on holiday. (Why doesn't this stuff ever happen when I'm there?) The sysadmin upgraded our Exchange server to Exchange 2010 and everone's subscriptions stopped. My Subscriptions showed an error message saying that the email address of one of the recipients is invalid. When you create a subscription, Reporting puts your Windows user name into the To field and most users have no permissions to edit it. By default, Reporting leaves it up to exchange to resolve that into an email address. This only works if Exchange is set up to translate aliases or 'short names' into email addresses. It turns out this leaves Exchange open to being used as a relay so it is disabled out of the box. You now have three options: Open up Exchange. That would be bad. Give all Reporting users the ability to edit the To field in a subscription. a) They shouldn't have to, it should just work. b) They don't really have any business subscribing anyone but themselves. Fix the report server to add the domain. This looks like the right choice and it works for us. See below for details. Pre-requisites: A single email domain name. A clear relationship between the Windows user name and the email address. eg. If the user name is joebloggs, then joebloggs@domainname needs to be the email address or an alias of it. Warning: Saving changes to the rsreportserver.config file will restart the Report Server service which effectively takes Reporting down for around 30 seconds. Time your action accordingly. Edit the file rsreportserver.config (most probably in the folder ..\Program Files[ (x86)]\Microsoft SQL Server\MSRS10_50[.instancename]\Reporting Services\ReportServer). There's a setting called DefaultHostName which is empty by default. Enter your email domain name without the leading '@'. Save the file. This domain name will be appended to any destination addresses that don't have a domain name of their own.

  • Is it evil to model JSON responses to classes when they are mostly smilar?

    - by Aybe
    Here's the problem : While implementing a C# wrapper for an online API (Discogs) I've been faced to a dilemma : quite often the responses returned have mostly similar members and while modeling these responses to classes, some questions surfaces on which way to go would be the best. Example : Querying for a 'release' or a 'master' will return an object that contains an array of 'artist', however these 'artists' do not exactly have the same members. Currently I decided to represent these 'artists' as a single 'Artist' class, against having respective 'ReleaseArtist' and 'MasterArtist' classes which soon becomes very confusing even though another problem arises : when a category (master or release) does not return these members, they will be null. Though it might sound confusing as well I find it less confusing than the former situation as I've tackled the problem by simply not showing null members when visualizing these objects. Is this the right approach to follow ? An example of these differences : public class Artist { public List<Alias> Aliases { get; set; } public string DataQuality { get; set; } public List<Image> Images { get; set; } public string Name { get; set; } public List<string> NameVariations { get; set; } public string Profile { get; set; } public string Realname { get; set; } public string ReleasesUrl { get; set; } public string ResourceUrl { get; set; } public string Uri { get; set; } public List<string> Urls { get; set; } } public class ReleaseArtist { public string Join { get; set; } public string Name { get; set; } public string Anv { get; set; } public string Tracks { get; set; } public string Role { get; set; } public string ResourceUrl { get; set; } public int Id { get; set; } }

  • How do I use IIS7 rewrite to redirect requests for (HTTP or HTTPS):// (www or no-www) .domainaliases.ext to HTTPS://maindomain.ext

    - by costax
    I have multiple domain names assigned to the same site and I want all possible access combinations redirected to one domain. In other words whether the visitor uses http://domainalias.ext or http://www.domainalias.ext or https://www.domainalias3.ext or https://domainalias4.ext or any other combination, including http://maindomain.ext, http://www.maindomain.ext, and https://www.maindomain.ext they are all redirected to https://maindomain.ext I currently use the following code to partially achieve my objectives: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="CanonicalHostNameRule" stopProcessing="true"> <match url="(.*)" /> <conditions> <add input="{HTTP_HOST}" pattern="^MAINDOMAIN\.EXT$" negate="true" /> </conditions> <action type="Redirect" redirectType="Permanent" url="https://MAINDOMAIN.EXT/{R:1}" /> </rule> <rule name="HTTP2HTTPS" stopProcessing="true"> <match url="(.*)" /> <conditions> <add input="{HTTPS}" pattern="off" ignoreCase="true" /> </conditions> <action type="Redirect" redirectType="Permanent" url="https://MAINDOMAIN.EXT/{R:1}" /> </rule> </rules> </rewrite> </system.webServer> </configuration> ...but it fails to work in all instances. It does not redirect to https://maindomain.ext when user inputs https://(www.)domainalias.ext So my question is, are there any programmers here familiar with IIS7 ReWrite that can help me modify my existing code to cover all possibilities and reroute all my domain aliases, loaded by themselves or using www in front, in HTTP or HTTPS mode, to my main domain in HTTPS format??? The logic would be: if entire URL does NOT start with https://maindomain.ext then REDIRECT to https://maindomain.ext/(plus_whatever_else_that_followed). Thank you very much for your attention and any help would be appreciated. NOTE TO MODS: If my question is not in the correct format, please edit or advise. Thanks in advance.

  • Server 2008 R2 Dns Lockup

    - by Richard Maynard
    Hi, We've deployed our first 2008 R2 server on a client site which has replaced their existing 2003 DC. This server provides DNS resolution services to all client machines on that site for general internet usage. Since using the 2008 R2 DNS services we have noticed every couple of days the DNS server starts timing out when requests to certain sites are made (google is the only example I can provide at this time although it seems to be larger sites with problems rather than small - CDN compatiblity issue?). When you restart the DNS Server service then resolution returns to normal... just only for a day or so. Is anybody aware of any significant changes to the DNS server architecture or configuration out of the box in R2 that may explain this intermittent behaviour? I have already tried the fix listed here to no avail: http://weblogs.asp.net/owscott/archive/2009/09/15/windows-server-2008-r2-dns-issues.aspx The following PS command prompt info illustrates the issue: PS C:\Users\Administrator.UK> nslookup Default Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 > www.google.com Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 Non-authoritative answer: Name: www.l.google.com Addresses: 66.102.9.99 66.102.9.104 66.102.9.105 66.102.9.103 66.102.9.147 Aliases: www.google.com > www.google.co.uk Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 * s8209001.uk.kingdomfaith.com can't find www.google.co.uk: Server failed Thanks in advance.

  • alias gcc='gcc -fpermissive' or modifying ./configure script

    - by robo
    I am compiling quite big project from source. The compilation always ends with: error: invalid conversion from ‘const char*’ to ‘char*’ [-fpermissive] I have already compiled this project one year ago. So I know a solution to this. Actualy I found more solutions: Adding a typecast to appropriate line of cpp code (It went to endless number of changes in each file. So I found next solution.) Modifying a makefile to compile that file with -fpermissive option. (I had to modify a lot of lines in each makefile. So I find even better solution.) "g++" or "gcc" was stored in a variable so I added -fpermissive to these variables. This is the best solution I have. It is sufficient to add this option to each makefile once. Unfortunately this software has big number of subdirectories. So I need to modify more than 100 makefiles. It took me whole day one year ago. Is there a way how to do this faster. What about this? alias gcc='gcc -fpermissive' I am not familiar with aliases. But it should be easy to try this. Is the syntax correct? And is this one correct? alias g++='g++ -fpermissive' ? And do I need to export the alias somehow? Will the make program respect the alias? Should I maybe change ./configure script? Or the ./configure.in? Or other file?

  • Grant access for users on a separate domain to SharePoint

    - by Geo Ego
    Hello. I just completed development of a SharePoint site on a virtual server and am currently in the process of granting users from a different domain to the site. The SharePoint domain is SHAREPOINT, and the domain with the users I want to give access to is COMPANY. I have provided them with a link to the site and added them as users via SharePoint, which is all I thought I would need to do. However, when they go to the link, the site shows them a SharePoint error page. In the security event log, I am showing the following: Event Type: Failure Audit Event Source: Security Event Category: Object Access Event ID: 560 Date: 3/18/2010 Time: 11:11:49 AM User: COMPANY\ThisUser Computer: SHAREPOINT Description: Object Open: Object Server: Security Account Manager Object Type: SAM_ALIAS Object Name: DOMAINS\Account\Aliases\00000404 Handle ID: - Operation ID: {0,1719489} Process ID: 416 Image File Name: C:\WINDOWS\system32\lsass.exe Primary User Name: SHAREPOINT$ Primary Domain: COMPANY Primary Logon ID: (0x0,0x3E7) Client User Name: ThisUser Client Domain: PRINTRON Client Logon ID: (0x0,0x1A3BC2) Accesses: AddMember RemoveMember ListMembers ReadInformation Privileges: - Restricted Sid Count: 0 Access Mask: 0xF Then, four of these in a row: Event Type: Failure Audit Event Source: Security Event Category: Object Access Event ID: 560 Date: 3/18/2010 Time: 11:12:08 AM User: NT AUTHORITY\NETWORK SERVICE Computer: SHAREPOINT Description: Object Open: Object Server: SC Manager Object Type: SERVICE OBJECT Object Name: WinHttpAutoProxySvc Handle ID: - Operation ID: {0,1727132} Process ID: 404 Image File Name: C:\WINDOWS\system32\services.exe Primary User Name: SHAREPOINT$ Primary Domain: COMPANY Primary Logon ID: (0x0,0x3E7) Client User Name: NETWORK SERVICE Client Domain: NT AUTHORITY Client Logon ID: (0x0,0x3E4) Accesses: Query status of service Start the service Query information from service Privileges: - Restricted Sid Count: 0 Access Mask: 0x94 Any ideas what permissions I need to grant to the user to get them access to SharePoint?

  • mdadm cron job sends email that cron has run

    - by Andrew
    I've got an Ubuntu 8.04 server using mdadm to create several RAID1 arrays. I created /etc/cron.hourly/mdadm as follows: #! /bin/sh set -e mdadm --monitor /dev/md0 /dev/md3 /dev/md4 --oneshot (Yes, the array numbers are not sequential, and I'm not using --scan beacuse I have a degraded array that may or may not have been used as swap and I can't delete, but I think that's a separate issue. If it's the underlying cause of this, I need to fix it.) mdadm sends me email (configured in the /etc/mdadm/mdadm.conf) on DegradedArray etc. events. This is the desired behaviour. What is not desired, and I can't work out, is why cron is sending me (relatively pointless) emails, via an alias in /etc/aliases: From: root@<hostname> (Cron Daemon) To: root@<hostname> Subject: Cron <root@<hostname>> cd / && run-parts --report /etc/cron.hourly Content-Type: text/plain; charset=ANSI_X3.4-1968 X-Cron-Env: <SHELL=/bin/sh> X-Cron-Env: <PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin> X-Cron-Env: <HOME=/root> X-Cron-Env: <LOGNAME=root> Message-Id: <id@hostname> Date: Fri, 7 May 2010 13:17:01 +0930 (CST) /etc/cron.hourly/mdadm: mdadm: Monitor using email address "<root_alias@domain>" from config file I've got a dozen other servers behaving correctly (mdadm sends email, cron doesnt') with identical /etc/crontab files: # /etc/crontab: system-wide crontab # <snip comments> SHELL=/bin/sh PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin # m h dom mon dow user command 17 * * * * root cd / && run-parts --report /etc/cron.hourly <snip anacron jobs> Should I simply remove the --report, or is there something else in my cron config somewhere causing this?

  • getting "No LoginModules configured" for JAAS login under WebSphere security domain

    - by user1739040
    I have a JAX-RPC web service running on WebSphere V7. It requires a UserNameToken for security. I have a custom login module (MyLoginModule) which extracts the username and password, and that module is defined as a JAAS application login in the websphere admin console. Using IBM RAD 8.0, I have bound the token consumer to the login module using the JAAS config name of the module. This all works fine and happy on my development server. Now I realize, that for deployment to another server, I am required to move the JAAS login from global security to a security domain. When I do that, it breaks my web service. I get this SOAP Fault message: com.ibm.wsspi.wssecurity.SoapSecurityException: WSEC6520E: Construction of the login context failed. The exception is : javax.security.auth.login.LoginException: No LoginModules configured for MyLoginModule According to the IBM docs: The JAAS application logins, the JAAS system logins, and the JAAS J2C authentication data aliases can all be configured at the domain level. By default, all of the applications in the system have access to the JAAS logins configured at the global level. The security runtime first checks for the JAAS logins at the domain level. If it does not find them, it then checks for them in the global security configuration. Configure any of these JAAS logins at a domain only when you need to specify a login that is used exclusively by the applications in the security domain. So I am looking to make sure my application is in the domain, and I have tried everything I can think of. (I have assigned the domain to "all scopes", to the entire cell, etc.) No luck, I keep getting the same error response to my web service client. Any help or hints are appreciated.

  • Unable to receive any emails using postfix, dovecot, mysql, and virtual domain/mailboxes

    - by stkdev248
    I have been working on configuring my mail server for the last couple of weeks using postfix, dovecot, and mysql. I have one virtual domain and a few virtual mailboxes. Using squirrelmail I have been able to log into my accounts and send emails out (e.g. I can send to googlemail just fine), however I am not able to receive any emails--not from the outside world nor from within my own network. I am able to telnet in using localhost, my private ip, and my public ip on port 25 without any problems (I've tried it from the server itself and from another computer on my network). This is what I get in my logs when I send an email from my googlemail account to my mail server: mail.log Apr 14 07:36:06 server1 postfix/qmgr[1721]: BE01B520538: from=, size=733, nrcpt=1 (queue active) Apr 14 07:36:06 server1 postfix/pipe[3371]: 78BC0520510: to=, relay=dovecot, delay=45421, delays=45421/0/0/0.13, dsn=4.3.0, status=deferred (temporary failure.

    I tried to run logwatch at follows [root@machine cron.daily]# ./0logwatch ERROR: Date::Manip unable to determine TimeZone. Execute the following command in a shell prompt: perldoc Date::Manip The section titled TIMEZONES describes valid TimeZones and where they can be defined. My date is as follows root@machine cron.daily]# date Thu Aug 23 06:25:21 GMT 2012 Now based on details in various forums I tried to fix this by setting /etc/timezone to “+0800” but it didn’t work My /etc/localtime points to /usr/share/zoneinfo/GMT and is managed by puppet How do I go about fixing this? I still want all my machines to be in GMT timezone.

  • Environment variables in bash_profile or bashrc?

    - by Viriato
    I have found this question [blog]: Difference between .bashrc and .bash_profile very useful but after seeing the most voted answer (very good by the way) I have further questions. Towards the end of the most voted, correct answer I see the statement as follows : Note that you may see here and there recommendations to either put environment variable definitions in ~/.bashrc or always launch login shells in terminals. Both are bad ideas. Why is it a bad idea (I am not trying to fight, I just want to understand)? If I want to set an environment variable and add it to the PATH (for example JAVA_HOME) where it would be the best place to put the export entry? in ~/.bash_profile or ~/.bashrc? If the answer to question number 2 is ~/.bash_profile, then I have two further questions: 3.1. What would you put under ~/.bashrc? only aliases? 3.2. In a non-login shell, I believe the ~/.bash_profile is not being "picked up". If the export of JAVA_HOME entry was in bash_profile would I be able to execute javac & java commands? Would it find them on the PATH? Is that the reason why some posts and forums suggest setting JAVA_HOME and alike to ~/.bashrc? Thanks in advance.

  • Connecting to RDS database from EC2 instance using bind9 CNAME alias

    - by mptre
    I'm trying to get internal DNS up and running on a EC2 instance. The main goal is to be able to define CNAME aliases for other AWS services. For example: Instead of using the RDS endpoint, which might change over time, an alias mysql.company.int can be used instead. I'm using bind9 and here's my config files: /etc/bind/named.conf.local zone "company.int" { type master; file "/etc/bind/db.company.int"; }; /etc/bind/db.company.int ; $TTL 3600 @ IN SOA company.int. company.localhost. ( 20120617 ; Serial 604800 ; Refresh 86400 ; Retry 2419200 ; Expire 604800 ) ; Negative Cache TTL ; @ IN NS company.int. @ IN A 127.0.0.1 @ IN AAAA ::1 ; CNAME mysql IN CNAME xxxx.eu-west-1.rds.amazonaws.com. The dig command ensures me my alias is working as excepted: $ dig mysql.company.int ... ;; ANSWER SECTION: mysql.company.int. 3600 IN CNAME xxxx.eu-west-1.rds.amazonaws.com. xxxx.eu-west-1.rds.amazonaws.com. 60 IN CNAME ec2-yyy-yy-yy-yyy.eu-west-1.compute.amazonaws.com. ec2-yyy-yy-yy-yyy.eu-west-1.compute.amazonaws.com. 589575 IN A zzz.zz.zz.zzz ... As far as I can understand a reverse zone isn't needed for a simple CNAME alias. However when I try to connect to MySQL using my newly created alias the operation is giving me a timeout. $ mysql -uuser -ppassword -hmysql.company.int ERROR 2003 (HY000): Can't connect to MySQL server on 'mysql.company.int' (110) Any ideas? Thanks in advantage!

  • Server 2008 R2 DNS Lockup / Stops Resolving Internet Names

    - by Richard Maynard
    We've deployed our first 2008 R2 server on a client site which has replaced their existing 2003 DC. This server provides DNS resolution services to all client machines on that site for general internet usage. Since using the 2008 R2 DNS services we have noticed every couple of days the DNS server starts timing out when requests to certain sites are made (google is the only example I can provide at this time although it seems to be larger sites with problems rather than small - CDN compatiblity issue?). When you restart the DNS Server service then resolution returns to normal... just only for a day or so. Is anybody aware of any significant changes to the DNS server architecture or configuration out of the box in R2 that may explain this intermittent behaviour? I have already tried the fix listed here to no avail: http://weblogs.asp.net/owscott/archive/2009/09/15/windows-server-2008-r2-dns-issues.aspx The following PS command prompt info illustrates the issue: PS C:\Users\Administrator.UK> nslookup Default Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 > www.google.com Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 Non-authoritative answer: Name: www.l.google.com Addresses: 66.102.9.99 66.102.9.104 66.102.9.105 66.102.9.103 66.102.9.147 Aliases: www.google.com > www.google.co.uk Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 * s8209001.uk.kingdomfaith.com can't find www.google.co.uk: Server failed

  • ServerName not working in Apache2 and Ubuntu

    - by CreativeNotice
    Setting up a dev LAMP server and I wish to allow dynamic subdomains, aka ted.servername.com, bob.servername.com. Here's my sites-active file <VirtualHost *:80> # Admin Email, Server Name, Aliases ServerAdmin [email protected] ServerName happyslice.net ServerAlias *.happyslice.net # Index file and Document Root DirectoryIndex index.html DocumentRoot /home/sysadmin/public_html/happyslice.net/public # Custom Log file locations LogLevel warn ErrorLog /home/sysadmin/public_html/happyslice.net/log/error.log CustomLog /home/sysadmin/public_html/happyslice.net/log/access.log combined And here's the output from sudo apache2ctl -S VirtualHost configuration: wildcard NameVirtualHosts and default servers: *:80 is a NameVirtualHost default server happyslice.net (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost happyslice.net (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost happyslice.net (/etc/apache2/sites-enabled/happyslice.net:5) Syntax OK The server hostname is srv.happyslice.net. As you can see from apache2ctl when I use happyslice.net I get the default virtual host, when I use a subdomain, I get the happyslice.net host. So the later is working how I want, but the main url does not. I've tried all kinds of variations here, but it appears that ServerName just isn't being tied to the correct location. Thoughts? I'm stumped. FYI, I'm running Apache2.1 and Ubuntu 10.04 LTS

  • NIS user not being added to NIS group

    - by Brian
    I have set up a NIS server and several NIS clients. I have a user and a group on the NIS server like so: /etc/passwd: myself:x:5000:5000:,,,:/home/myself:/bin/bash /etc/group: fishy:x:3001:otheruser,etc,myself,moreppl I imported the users and groups on the NIS client by adding +:::::: to /etc/passwd and +::: to /etc/group. I can log in to the NIS client, but when I run groups, fishy is not listed. But getent group fishy shows that it was imported correctly and lists me as a member. And if I do sudo su - myself, then suddenly groups says I am in the group! I also had nscd installed, and the groups worked correctly for a while. It seemed like after being logged in for a while, I would silently be dropped out of the group. If I restarted nscd and logged in again, then the groups worked correctly...for a while. There are no UID or GID conflicts with local users or groups. Update: Contents of /etc/nsswitch.conf: passwd: compat group: compat shadow: compat hosts: files nis dns networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis aliases: nis files

  • Disable IPv6 on Debian VPS (Virtuozzo!)

    - by chris_l
    I have a Debian Lenny VPS, that's running virtualized by Parallels/Virtuozzo. Currently, the network interface doesn't have an IPv6 address - and that's good, because I don't have an ip6tables configuration. But I assume, that I could wake up one day, and ifconfig will show me an ipv6 address for the interface - because I have no control over the kernel or its modules - they're under the control of the hosting company. That would leave the server completely vulnerable to attacks from IPv6 addresses. What would be the best way to disable IPv6 (for the interface or maybe for the entire host)? Usually I would simply disable the kernel module, but that's not possible in this case. Update Maybe I should add, that I can use iptables and everything normally (I'm root on the VPS), but I can't make changes to the kernel or load kernel modules because of the way Virtuozzo works (shared kernel). lsmod always returns nothing. I can't call ip6tables -L (it says that I need to insmod, or that the kernel would have to be upgraded). I don't think, that changes to /etc/modprobe.d/aliases would have any effect, or do they? Networking Config? I thought, that maybe I can turn IPv6 off from /etc/network/... Is that possible? I just see, that they've set up avahi, so I should probably change the setting use-ipv6=yes to "no" in /etc/avahi/avahi.conf (?) Has anybody already tried this solution, and can I rely on it? I don't know too much about avahi. Would it actually have any effect? Or could it even bring my entire interface down, once IPv6 is enabled by the kernel?

  • Adding new SPNs to existing service ids

    - by jmh
    We have a tomcat server using spring-security kerberos to authenticate users to the webpage against active directory. There are around 25 domain controllers. The site has two CNAME based DNS aliases. The site currently has one Service ID with SPNs registered for the DNS A record as well as each of the CNAMEs. While everything is working right now, I don't know how to reliably change this configuration without possible downtime. The reason is that clients cache kerberos tickets: http://www.juniper.net/techpubs/en_US/uac4.2/topics/concept/user-role-active-directory-about.html The 'kerbtray.exe' program is helpful for viewing and deleting Kerberos tickets on the endpoint. Old tickets must be purged from the endpoint if SPNs are updated or passwords are changed (assuming the endpoint still has a cached copy of the ticket from a prior SPNEGO request to the MAG Series device. During testing, you should purge tickets before each authentication request. Description of "klist" program used to inspect/delete cached tickets: http://technet.microsoft.com/en-us/library/hh134826.aspx So if each of the clients (users running windows) who connect to my web server have kerberos tickets that become invalid as soon as I update the SPNs or passwords, how do I ensure changes are seamless? Are there any operations that can be done safely? I can't just ask all of the users to install klist and delete their old tickets.
