  • Debootstrap Ubuntu over NFS leads to mknod I/O error

    - by Aaron B. Russell
    Hi everyone, I'm trying to prepare an Ubuntu environment for a diskless machine that will PXE boot and mount an NFS share as it's root. I've currently got another Ubuntu machine mounting the NFS share and I'm trying to debootstrap into it, but it has trouble creating devices over NFS: root@kimiko:~# mount | grep Seiuchi 192.168.0.203:/mnt/user/Seiuchi on /mnt type nfs (rw,addr=192.168.0.203) root@kimiko:~# debootstrap --arch i386 maverick /mnt http://gb.archive.ubuntu.com/ubuntu/ mknod: `/mnt/test-dev-null': Input/output error E: Cannot install into target '/mnt' mounted with noexec or nodev My NFS rule on the unRAID server is 192.168.0.201/32(rw,no_root_squash,sync). I don't have the noexec or nodev options set. I've not got much experience with NFS, so I'm probably missing something basic in the way I'm sharing this, but my attempts at Googling for an answer isn't really turning anything useful up. Does anyone have suggestions on what I might have missed or maybe relevant docs? Edit: Creating normal files (and directories) works just fine, I just can't create devices... root@kimiko:/mnt# mkdir foo root@kimiko:/mnt# cd foo root@kimiko:/mnt/foo# touch bar root@kimiko:/mnt/foo# mknod quux c 4 64 mknod: `quux': Input/output error root@kimiko:/mnt/foo# ls bar

  • Load balancing a Windows File Share using HA-Proxy

    - by NathanE
    After pulling my hair out over DFS I just had this weird and potentially dangerous idea come into my head whereby, just possibly, I might be able to use HA-Proxy to load balance a file share between servers. I've done some remedial packet traces and it does appear that TCP port 445 is the only thing involved in using Windows file sharing. I've always thought for many years that UDP 139, 135 etc were also involved in at least establishing the connection - but apparently not! So I setup a basic test: listen SMBTest *:445 mode tcp server Smb1 172.16.61.201:445 server Smb2 172.16.61.202:445 And you'll never guess what... it works??? (!) Now obviously there is the whole concern about synchronisation between the file servers (of course). That could easily be taken care of with a little bit of Robocopy script. And considering I only need a HA read-only file share there wouldn't be any issues with regard to file locking etc. Can anyone tell me if what I'm playing with here is fire? I really didn't think it would work at all and now I'm a little shocked. What would be the downsides? Could this be relied upon for a production environment?

  • Why Ubuntu could treat hosts file so strange?

    - by z4y4ts
    I have almost fresh Ubuntu desktop box. OS was installed two weeks ago and updated from karmic repositories. Last week I had no problems with DNS. But this week something had changed. I'm not sure what and when, and not sure whether I changed any configs. So now I have some really weird situation. According to logs name resolving should work normally. /etc/hosts 127.0.0.1 localhost test 127.0.1.1 desktop /etc/host.conf order hosts,bind multi on /etc/resolv.conf # Generated by NetworkManager search search servers obtained via DHCP nameserver 192.168.0.3 /etc/nsswitch.conf passwd: compat group: compat shadow: compat hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis But if fact it is not. user@test ~ping test PING localhost (127.0.0.1) 56(84) bytes of data. [skip] Pinging is ok. user@test ~host test test.myviacube.com has address xx.xxx.161.201 But pure I suspect that NetworkManager might cause this misbehavior, but don't know where to start to check it. Any thoughts, suggestions?

  • ISC DHCPD IPv6 for multiple interfaces

    - by Seoman
    I want to assign multiple IPv6 to a server with multiple NIC. As IPv6 RFC defines, each server has a unique DUID that can have one of the 3 formats (LL, LLT or enterprise). And each NIC has an IAID. So a request from NIC1 its the DUID and the IAID of the NIC1 and the request from NIC2 its the same DUID but the IAID its different. The problem is that from a Centos box, when I ask for an IP in 2 different interfaces, I get the same IP. I can't find how to specify host entry based on DUID and the IAID. I see some people generating a unique DUID based on the MAC of the NIC but this is not IPv6 RFC says. What I tried is: host entry1 { host-identifier option dhcp6.client-id 00:01:00:01:19:fc:f8:1c:52:54:00:7e:c9:ec; option dhcp6.ia-na "00:09:40:5d"; fixed-address6 2001:db8:0:1::202; } host entry2 { host-identifier option dhcp6.client-id 00:01:00:01:19:fc:f8:1c:52:54:00:7e:c9:ec; option dhcp6.ia-na "00:7e:c9:ec"; fixed-address6 2001:db8:0:1::201; } This causes a Segmentation Fault in the client (what is scary...). I guess is not the right use for ia-na option but I don't see any other option.

  • Possible to IPSec VPN Tunnel Public IP Addresses?

    - by caleban
    A customer uses an IBM SAS product over the internet. Traffic flows from the IBM hosting data center to the customer network through Juniper VPN appliances. IBM says they're not tunneling private IP addresses. IBM says they're tunneling public IP addresses. Is this possible? What does this look like in the VPN configuration and in the packets? I'd like to know what the source/destination ip/ports would look like in the encrypted tunneled IPSec Payload and in the IP packet carrying the IPSec Payload. IPSec Payload: source:1.1.1.101:1001 destination:2.2.2.101:2001 IP Packet: source:1.1.1.1:101 destination:2.2.2.1:201 Is it possible to send public IP addresses through an IPSec VPN tunnel? Is it possible for IBM to send a print job from a server on their network using the static-nat public address over a VPN to a printer at a customer network using the printer's static-nat public address? Or can a VPN not do this? Can a VPN only work with interesting traffic from and to private IP addresses?

  • Setup LDAP In WAMP

    - by Cory Dee
    I'm having a really tough time getting the LDAP extensions to work in PHP on a WAMP server. Here is what I've done: Went to C:\Program Files\Apache Software Foundation\Apache2.2\modules and made sure that mod_ldap.so exists. I've gone into C:\Program Files\Apache Software Foundation\Apache2.2\conf\httpd.conf and made sure that this line is not commented out: LoadModule ldap_module modules/mod_ldap.so I've gone into C:\Program Files\PHP\php.ini and made sure this line is not commented out: extension=php_ldap.dll I've made sure C:\Program Files\PHP is in the Path I've made sure C:\Program Files\PHP contains libeay32.dll and ssleay32.dll Restart apache phpinfo() still doesn't show mod_ldap as being turned on. It shows util_ldap under Loaded Modules, but that's the only reference anywhere to LDAP. For a bit more background, I originally posted this on SO.

  • How is it possible that I can do a host lookup but not a curl?

    Has anyone ever seen this before? Note that this happens not only with google.com, but with every domain I try. It's a wireless connection (WEP), but I'm not sure how that would be relevant: $ curl -v google.com # This takes about 60s to return * getaddrinfo(3) failed for google.com:80 * Couldn't resolve host 'google.com' * Closing connection #0 curl: (6) Couldn't resolve host 'google.com' $ host google.com google.com has address 209.85.148.106 google.com has address 209.85.148.147 google.com has address 209.85.148.99 google.com has address 209.85.148.103 google.com has address 209.85.148.104 google.com has address 209.85.148.105 google.com mail is handled by 30 alt2.aspmx.l.google.com. google.com mail is handled by 40 alt3.aspmx.l.google.com. google.com mail is handled by 50 alt4.aspmx.l.google.com. google.com mail is handled by 10 aspmx.l.google.com. google.com mail is handled by 20 alt1.aspmx.l.google.com. $ cat /etc/resolv.conf # Generated by NetworkManager nameserver 192.168.1.201 $ cat /etc/hosts 127.0.0.1 localhost ::1 localhost $ netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.1.254 0.0.0.0 UG 0 0 0 wlan0 127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0

  • IP tables blocking access to most hosts but some accesses being logged

    - by epo
    What am I getting wrong? A while back I locked down my web hosting service while hardening it or at least trying to. Apache listens on port 80 only and I set up iptables using the following: IPS="list of IPs" iptables --new-chain webtest # Accept all established connections iptables -A INPUT --protocol tcp --dport 80 --jump webtest iptables -A INPUT --match state --state ESTABLISHED,RELATED --jump ACCEPT iptables -A webtest --match state --state ESTABLISHED,RELATED --jump ACCEPT for ip in $IPS; do iptables -A webtest --match state --state NEW --source $ip --jump ACCEPT done iptables -A webtest --jump DROP However looking at my apache logs I notice various log entries in access_log, e.g. 221.192.199.35 - - [16/May/2010:13:04:31 +0100] "GET http://www.wantsfly.com/prx2.php?hash=926DE27C156B40E55E4CFC8F005053E2D81E6D688AF0 HTTP/1.0" 404 206 "-" "Mozilla/ 4.0 (compatible; MSIE 6.0; Windows NT 5.0)" 201.228.144.124 - - [16/May/2010:11:54:16 +0100] "GET /w00tw00t.at.ISC.SANS.DFind:) HTTP/1.1" 400 226 "-" "-" 207.46.195.224 - - [16/May/2010:04:06:48 +0100] "GET /robots.txt HTTP/1.1" 200 311 "-" "msnbot/2.0b (+http://search.msn.com/msnbot.htm)" How are these slipping through? I don't mind the indexing bots (though I am a little surprised to see them get through). I suppose they must be getting through using the ESTABLISHED,RELATED rules. And no, I can't for the life of me remember why the first match state rule is there So 2 questions: is there a better way to set up iptables to restrict access to specified hosts? How exactly are these 3 examples slipping through?

  • Is there any way for ME to improve routing to an overseas server? [migrated]

    - by Simon Hartcher
    I am trying to make a connection to a gaming server in Asia from Australia, but my ISP routes my connection through the US. Tracing route to worldoftanks-sea.com [116.51.25.54]over a maximum of 30 hops: 1 <1 ms <1 ms <1 ms 192.168.1.1 2 34 ms 42 ms 45 ms 10.20.21.123 3 40 ms 40 ms 43 ms 202.7.173.145 4 51 ms 42 ms 36 ms syd-sot-ken-crt1-ge-6-0-0.tpgi.com.au [202.7.171.121] 5 175 ms 200 ms 195 ms ge5-0-5d0.cir1.seattle7-wa.us.xo.net [216.156.100.37] 6 212 ms 228 ms 229 ms vb2002.rar3.sanjose-ca.us.xo.net [207.88.13.150] 7 205 ms 204 ms 206 ms 207.88.14.226.ptr.us.xo.net [207.88.14.226] 8 207 ms 215 ms 220 ms xe-0.equinix.snjsca04.us.bb.gin.ntt.net [206.223.116.12] 9 198 ms 201 ms 199 ms ae-7.r20.snjsca04.us.bb.gin.ntt.net [129.250.5.52] 10 396 ms 391 ms 395 ms as-6.r20.sngpsi02.sg.bb.gin.ntt.net [129.250.3.89] 11 383 ms 384 ms 383 ms ae-3.r02.sngpsi02.sg.bb.gin.ntt.net [129.250.4.178] 12 364 ms 381 ms 359 ms wotsg1-slave-54.worldoftanks.sg [116.51.25.54] Trace complete. Since I think it will be unlikely that my ISP will do anything, are there any ways to improve my routing to the server without them having to intervene? NB. The game runs predominately over UDP, so I believe most low ping services are out of the question, as they rely on TCP traffic.

  • using gmail as email relay for sendmail

    - by Nikita
    I used to be able to send emails using a gmail account & sendmail configured using one of the guides on the Internet, for example: http://appgirl.net/blog/configuring-sendmail-to-relay-through-gmail-smtp/ This is a small server and I've recently moved it to a different house. And sendmail has stop working. The only thing different in the network setup is a new router. What is happening: In the log files, I see the following error: ...stat=Deferred: smtp.gmail.com: No route to host When I run from the command line: strace sendmail -f A -t B -u "Subject" -m "Message" -tls=yes ssl=yes -s smtp.gmail.com:587 -xu A -xp XYZ It hangs on this call: recvfrom(3, "m0\201\203\0\1\0\0\0\0\0\0\4ares\3lan\0\0\34\0\1", 8192, 0, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("192.168.1.254")}, [16]) = 26 close(3) = 0 time(NULL) = 1339997943 open("/etc/localtime", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=3477, ...}) = 0 fstat64(3, {st_mode=S_IFREG|0644, st_size=3477, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb76ff000 read(3, "TZif2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\4\0\0\0\4\0\0\0\0"..., 4096) = 3477 _llseek(3, -24, [3453], SEEK_CUR) = 0 read(3, "\nEST5EDT,M3.2.0,M11.1.0\n", 4096) = 24 close(3) = 0 munmap(0xb76ff000, 4096) = 0 socket(PF_FILE, SOCK_DGRAM|SOCK_CLOEXEC, 0) = 3 connect(3, {sa_family=AF_FILE, path="/dev/log"}, 110) = 0 send(3, "<18>Jun 18 01:39:03 sendmail[268"..., 96, MSG_NOSIGNAL) = 96 nanosleep({60, 0}, So it looks like at some point it tries to resolve the DNS name, but I don't have anything running on 53, so it dies out and then just hangs. The other interesting thing is that msmtp works just fine on the same server. Update: ares in strace output is actually the name of my server, but .254 IP address is the address of the router. Could anyone tell me why this is happening or what further steps can I take to investigate the issue? Thanks!

  • Iptables ignoring a rule in the config file

    I see lot of established connections to my apache server from the ip 188.241.114.22 which eventually causes apache to hang . After I restart the service everything works fine.

  • VirtualBox doesn't see raw partitions

    - by smbear
    What I want to achieve is to set up virtual machine with VirtualBox. Host OS is Windows 7 Home Premium, guest will be (k)Ubuntu 12.04 on a raw partition. The first problem is that when I issue following command: VBoxManage.exe internalcommands listpartitions -rawdisk \\.\PhysicalDrive0 I get following result: Number Type StartCHS EndCHS Size (MiB) Start (Sect) 1 0xee 0 /0 /1 1023/254/63 715404 1 I'm guessing that VirtualBox is unable to see my partitions. If I use diskpart tool, then all partitions are listed correctly (note Polish language version of Windows): DISKPART> select disk 0 Obecnie wybranym dyskiem jest dysk 0. DISKPART> list partition Partycja ### Typ Rozmiar Przesuniecie ------------- ---------------- ------- ------------ Partycja 1 System 200 MB 1024 KB Partycja 2 Zarezerwowany 128 MB 201 MB Partycja 3 Podstawowy 139 GB 329 MB Partycja 5 Nieznany 4883 KB 140 GB Partycja 6 Podstawowy 50 GB 140 GB Partycja 7 Podstawowy 484 GB 190 GB Partycja 4 Odzyskiwanie 24 GB 674 GB Additional note: my PC is using EFI to boot OS.

  • Bandwidth monitoring with iptables for non-router machine

    - by user1591276
    I came across this tutorial here that describes how to monitor bandwidth using iptables. I wanted to adapt it for a non-router machine, so I want to know how much data is going in/coming out and not passing through. Here are the rules I added: iptables -N ETH0_IN iptables -N ETH0_OUT iptables -I INPUT -i eth0 -j ETH0_IN iptables -I OUTPUT -o eth0 -j ETH0_OUT And here is a sample of the output: user@host:/tmp$ sudo iptables -x -vL -n Chain INPUT (policy ACCEPT 1549 packets, 225723 bytes) pkts bytes target prot opt in out source destination 199 54168 ETH0_IN all -- eth0 * 0.0.0.0/0 0.0.0.0/0 Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 1417 packets, 178128 bytes) pkts bytes target prot opt in out source destination 201 19597 ETH0_OUT all -- * eth0 0.0.0.0/0 0.0.0.0/0 Chain ETH0_IN (1 references) pkts bytes target prot opt in out source destination Chain ETH0_OUT (1 references) pkts bytes target prot opt in out source destination As seen above, there are no packet and byte values for ETH0_IN and ETH0_OUT, which is not the same result in the tutorial I referenced. Is there a mistake that I made somewhere? Thanks for your time.

  • How can I write an excel formula to do row based calculations; where certain conditions need to be met?

    - by BDY
    I am given: An excel sheet contains around 200 tasks (described in rows 2-201 in Column A). Each task can be elegible for a max of two projects (There are 4 projects in total, called "P1-P4" - drop down lists in Columns B and D); and this with a specific %-rate allocation (columns C & E - Column C refers to the Project Column B, and Column E refers to the Project in Column D). Column F shows the amount of work days spent on each task. Example in row 2: Task 1 (Column A); P1 (Column B) ; 80% (Column C) ; P3 (Column D) ; 20% (Column E) ; 3 (Column F) I need to know the sum of the working days spent on Project P3 respecting the %-rate for elegibility. I know how to calculate it for each Task (each Row) - e.g. for Task 1: =IF(B2="P3";C2*F2)+IF(D2="P3";E2*F2) However instead of repeating this for each task, I need a formula that adds them all together. Unfortunately the following formula shows me an error: =IF(B2:B201="P3";C2:C201*F2:F201)+IF(D2:D201="P3";E2:E201*F2:F201) Can anyone help please? Thank you!!

  • random generator to obtain data from array not displaying

    - by Yang Jie Domodomo
    I know theres a better solution using arc4random (it's on my to-try-out-function list), but I wanted to try out using the rand() and stand(time(NULL)) function first. I've created a NSMutableArray and chuck it with 5 data. Testing out how many number it has was fine. But when I tried to use the button function to load the object it return me with object <sampleData: 0x9a2f0e0> - (IBAction)generateNumber:(id)sender { srand(time(NULL)); NSInteger number =rand()% ds.count ; label.text = [NSString stringWithFormat:@"object %@", [ds objectAtIndex:number] ]; NSLog(@"%@",label.text); } While I feel the main cause is the method itself, I've paste the rest of the code below just incase i made any error somewhere.

  • Synchronous communication using NSOperationQueue

    - by chip_munks
    I am new to Objective C programming. I have created two threads called add and display using the NSInvocationOperation and added it on to the NSOperationQueue. I make the display thread to run first and then run the add thread. The display thread after printing the "Welcome to display" has to wait for the results to print from the add method. So i have set the waitUntilFinished method. Both the Operations are on the same queue. If i use waitUntilFinished for operations on the same queue there may be a situation for deadlock to happen(from apples developer documentation). Is it so? To wait for particular time interval there is a method called waitUntilDate: But if i need to like this wait(min(100,dmax)); let dmax = 20; How to do i wait for these conditions? It would be much helpful if anyone can explain with an example. EDITED: threadss.h ------------ #import <Foundation/Foundation.h> @interface threadss : NSObject { BOOL m_bRunThread; int a,b,c; NSOperationQueue* queue; NSInvocationOperation* operation; NSInvocationOperation* operation1; NSConditionLock* theConditionLock; } -(void)Thread; -(void)add; -(void)display; @end threadss.m ------------ #import "threadss.h" @implementation threadss -(id)init { if (self = [super init]) { queue = [[NSOperationQueue alloc]init]; operation = [[NSInvocationOperation alloc]initWithTarget:self selector:@selector(display) object:nil]; operation1 = [[NSInvocationOperation alloc]initWithTarget:self selector:@selector(add) object:nil]; theConditionLock = [[NSConditionLock alloc]init]; } return self; } -(void)Thread { m_bRunThread = YES; //[operation addDependency:operation1]; if (m_bRunThread) { [queue addOperation:operation]; } //[operation addDependency:operation1]; [queue addOperation:operation1]; //[self performSelectorOnMainThread:@selector(display) withObject:nil waitUntilDone:YES]; //NSLog(@"I'm going to do the asynchronous communication btwn the threads!!"); //[self add]; //[operation addDependency:self]; sleep(1); [queue release]; [operation release]; //[operation1 release]; } -(void)add { NSLog(@"Going to add a and b!!"); a=1; b=2; c = a + b; NSLog(@"Finished adding!!"); } -(void)display { NSLog(@"Into the display method"); [operation1 waitUntilFinished]; NSLog(@"The Result is:%d",c); } @end main.m ------- #import <Foundation/Foundation.h> #import "threadss.h" int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; threadss* thread = [[threadss alloc]init]; [thread Thread]; [pool drain]; return 0; } This is what i have tried with a sample program. output 2011-06-03 19:40:47.898 threads_NSOperationQueue[3812:1503] Going to add a and b!! 2011-06-03 19:40:47.898 threads_NSOperationQueue[3812:1303] Into the display method 2011-06-03 19:40:47.902 threads_NSOperationQueue[3812:1503] Finished adding!! 2011-06-03 19:40:47.904 threads_NSOperationQueue[3812:1303] The Result is:3 Is the way of invoking the thread is correct. 1.Will there be any deadlock condition? 2.How to do wait(min(100,dmax)) where dmax = 50.

  • PDC and Tech-Ed Europe Slides and Code

    - by Stephen Walther
    I spent close to three weeks on the road giving talks at Tech-Ed Europe (Berlin), PDC (Los Angeles), and the Los Angeles Code Camp (Los Angeles). I got to talk about two topics that I am very passionate about: ASP.NET MVC and Ajax. Thanks everyone for coming to all my talks! At PDC, I announced all of the new features of our ASP.NET Ajax Library. In particular, I made five big announcements: ASP.NET Ajax Library Beta Released – You can download the beta from Ajax.CodePlex.com ASP.NET Ajax Library includes the AJAX Control Toolkit – You can use the Ajax Control Toolkit with ASP.NET MVC. ASP.NET Ajax Library being contributed to the CodePlex Foundation – ASP.NET Ajax is the founding project for the CodePlex Foundation (see CodePlex.org) ASP.NET Ajax Library is receiving full product support – Complain to Microsoft Customer Service at midnight on Christmas ASP.NET Ajax Library supports jQuery integration – Use (almost) all of the Ajax Control Toolkit controls in jQuery For more details on the Ajax announcements, see James Senior’s blog entry on the Ajax announcements at: http://jamessenior.com/post/News-on-the-ASPNET-Ajax-Library.aspx In my MVC talks, I discussed the new features being introduced with ASP.NET MVC 2. Here are three of my favorite new features: Client Validation – Client validation done the right way. Do your validation in your model and let the validation bubble up to JavaScript code automatically. Areas – Divide your ASP.NET MVC application into sub-applications. Great for managing both medium and large projects. RenderAction() – Finally, a way to add content to master pages and multiple pages without doing anything strange or twisted. There are demos of all of these features in the MVC downloads below. Here are the power point and code from all of the talks: PDC – Introducing the New ASP.NET Ajax Library PDC – ASP.NET MVC: The New Stuff Tech-Ed Europe - What's New in Microsoft ASP.NET Model-View-Controller Tech-Ed Europe - Microsoft ASP.NET AJAX: Taking AJAX to the Next Level

  • Oracle Fusion Middleware-the best middleware for Siebel

    - by divya.malik
    With many choices available for Siebel customers today, selecting the right solutions to deliver the most value out of your applications  is challenging. What is Oracle Fusion Middleware? Oracle Fusion Middleware is a suite of products that Oracle offers to customers. It is a modern middleware foundation for building applications. It is certified with all of the Oracle Applications families, and it is also the foundation of Fusion Applications. There are a number of different components to Fusion Middleware. Some of the most important are: the SOA suite which provides the integration infrastructure to allow different applications to connect to each other. There is a Business Intelligence toolset that enables allows you to get biz intelligence out of the applications, there is a portal that allows you to build a  UI on top of different applications. Content management to manage invoices and other unstructured data that goes into the application and finally an identity management system to lower costs  of running your applications. So four ways to think about Oracle Fusion Middleware are: Use Fusion Middleware to connect and integrate different applications Use it to get business intelligence and insight out of the application Use it to customize or extend applications and build a composite applications user interface Use it to lower the cost of managing your applications Why Fusion Middleware? Fusion middleware is standards based, gives you a very open architecture that enables you to extend your apps to other systems, every piece of Fusion Middleware is a leader in its area (best of breed), it is hot-pluggable and certified on every application in the Oracle Applications family. Today, over 90,000 customers use Oracle Fusion Middleware applications. To learn more about Oracle Fusion Middleware for Siebel, read this white paper.

  • Building services with .Net Part 1

    - by Allan Rwakatungu
    On the 26th of May 2010 , I made a presentation to the .NET user group meeting (thanks to Malisa Ncube for organizing this event every month … ). If you missed my presentation , we talked about why we should all be building services … better still using the .NET framework. This blog post is an introduction to services , why you would want to build services and how you can build services using the .NET framework. What is a service? OASIS defines service as "a mechanism to enable access to one or more capabilities, where the access is provided using a prescribed interface and is exercised consistent with constraints and policies as specified by the service description." [1]. If the above definition sounds to academic , you can also define a service as loosely coupled units of functionality that have no calls to each other embedded in the. Instead of services embedding calls to each other in their service code they use defined protocols that describe how services pass and parse messages. This is a good way to think about services if you’re from an objected oriented background. While in object oriented programming functions make calls to each other, in service oriented programming, functions pass messages between each other. Why would you want to use services? 1. If your enterprise architecture looks like this   Services are the building blocks for SOA . With SOA you can move away from the sphaggetti infrastructure that is common in most enterprises. The complexity or lack of visibility of the integration points in your enterprises makes it difficult and costly to implement new initiatives and changes into the business - and even impossible in some cases - as it is not possible to identify the impact a change in one system might have to other systems. With services you can move to an architecture like this Your building blocks from Spaghetti infrastructure to something that is more well-defined and manageable to achieve cost efficiency and not least business agility - enabling you to react to changes in the market with speed and achieve operational efficiency and control are services. 2. If you want to become the Gates or Zuckerburger. Have you heard about Web 2.0 ? Mashups? Software as a service (SAAS) ? Cloud computing ?   They all offer you the opportunity to have scalable but low cost business models and they built using services.  Some of my favorite companies that leverage services for their business models include  https://www.salesforce.com/ (cloud CRM) http://www. twitter.com (more people use twitter clients built by 3rd parties than their official clients) http://www.kayak.com/ (compares data from other travel sites to give information to users in one location) Services with the .NET framework      If you are a .NET developer and you want to develop services, Windows Communication Framework (WCF) is the tool for you. WCF is Microsoft’s unified programming model (service model) for building service oriented applications. ( Before .NET 3.0 you had several models for programming services in .NET including .NET remoting, Web services (ASMX), COM +, Microsoft Messaging queuing (MSMQ) etc, after .NET 3.0 the programming model was unified into one i.e. WCF ). Windows Communication Framework (WCF) provides you 1. An Software Development Kit (SDK) for creating SOA applications 2. A runtime for running services on the Windows platform Why should you use Windows Communication Foundation if you’re programming services?   1. It supports interoperable and open standards e.g. WS* protocols for programming SOAP services 2. It has a unified programming model. Whether you use TCP or Http or Pipes or transmitting using Messaging Queues, programmers need to learn just one way to program. Previously you had .NET remoting, MSMQ, Web services, COM+ and they were all done differently 3. Productive programming model You don’t have to worry about all the plumbing involved to write services. You have a rich declarative programming model to add stuff like logging, transactions, and reliable messages in-built in the Windows Communication Framework. Understanding services in WCF The basic principles of WCF are as easy as ABC A – Address This is where the service is located B- Binding This describes how you communicate with the service e.g. Use TCP, HTTP or both. How to exchange security information with the service etc. C – Contract This defines what the service can do. E.g. Pay water bill, Make a phone call A - Addresses In WCF, an address is a combination of transport, server name, port and path Example addresses may include http://localhost:8001 net.tcp://localhost:8002/MyService net.pipe://localhost/MyPipe net.msmq://localhost/private/MyService net.msmq://localhost/MyService B- Binding   There are numerous ways to communicate with services , different ways that a message can be formatted/sent/secured, that allows you to tailor your service for the compatibility/performance you require for your solution. Transport You can use HTTP TCP MSMQ , Named pipes, Your own custom transport etc Message You  can send a plain text binary, Message Transmission Optimization Mechanism (MTOM) message Communication security No security Transport security Message security Authenticating and authorizing callers etc Behaviour You service can support Transactions Be reliable Use queues Support ajax etc C - Contract You define what your service can do using Service contracts :- Define operations that your service can do, communications and behaviours Data contracts :- Define the messages that are passed from and into your service and how they are formatted Fault contracts :- Defines errors types in your service   As an example, suppose your service service shows money. You define your service contract using a interface [ServiceContract] public interface IShowMeTheMoney {   [OperationContract]    Money Show(); } You define the data contract by annotating a class it with the Data Contract attribute and fields you want to pass in the message as Data Members. (Note:- In the latest versions of WCF you dont have to use attributes if you passing all the objects properties in the message) [DataContract] public Money {   [DataMember]   public string Currency { get; set; }   [DataMember]   public Decimal Amount { get; set; }   public string Comment { get; set; } } Features of Windows Communication Foundation Windows Communication Foundation is not only simple but feature rich , offering you several options to tweak your service to fit your business requirements. Some of the features of WCF include 1. Workflow services You can combine WCF with Windows WorkFlow Foundation (WWF) to write workflow type services 2. Control how your data (messages) are transferred and serialized e.g. you can serialize your business objects as XML or binary 3. control over session management , instance creation and concurrency management without writing code if you like 4. Queues and reliable sessions. You can store messages from the sending client and later forward them to the receiving application. You can also guarantee that messages will arrive at their destincation. 5.Transactions:  You can have different services participate in a transaction operations that can be rolled back if needed 6. Security. WCF has rich features for authorization and authentication  as well as keep audit trails 7. Web programming model. WCF allows developers to expose services as non SOAP endpoints 8. Inbuilt features that you can use to write JSON and services that support AJAX applications And lots more In my next blog I will show you how you can use WCF features to write a real world business service.               Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 ]] /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}
