Help With Virtual server

Hi, I'm trying to get virtual server set up on my computer. I seem to be having trouble with my computer's configuration, I've edited ssh_config to use port 2222 (port 22 is blocked by my ISP) and to use GatewayPorts, so I know the connection is reaching my computer, but ssh -v [email protected] gives me the following:
OpenSSH_4.2p1, OpenSSL 0.9.7i 14 Oct 2005
debug1: Reading configuration data /etc/ssh_config
debug1: Connecting to 207.148.144.12 [207.148.144.12] port 2222.
debug1: connect to address 207.148.144.12 port 2222: Connection refused
ssh: connect to host 207.148.144.12 port 2222: Connection refused
I've played around with my config files and can't find a way to get it not to be refused. Remote login is on. I'm not a UNIX user much at all so I might need a bit more help
Do I have to enter an authentication name in my configuration somehwere? Have I forgoetten to do anything? And is it just me or is it actually telling me its October of last year?
Thanks in advance,
~Stuart Barth

Are you trying to connect to port 2222 on the server? if so, changing ssh_config isn't going to have any effect.
ssh_config controls the ssh client configuration. In addition you need to tell the server to listen on port 2222 as well. It doesn't sound like you've done that.
Normally this would be controlled by the file /etc/sshd_config, but in the case of Mac OS X, sshd doesn't actually run as a daemon, so even this won't work.
Mac OS X uses launchd to manage the sshd server - invoking the sshd process when a network connection comes in. Therefore it's launchd that you need to change to tell it to listen to port.
You'll need to edit the file /System/Library/LaunchDaemons/ssh.plist and change the section:
<pre class=command> <key>SockServiceName</key>
<string>ssh</string></pre>
to replace 'ssh' with the port number you want to use (off hand I'm not sure if substituting a port name with a number will work, but it's worth a try.
The alternative, and somewhat simpler, option is to setup port forwarding on your router (assuming you're using some kind of NAT router) to forward connections from port 2222 on the public interface to port 22 on the server. This will only work if your router supports changing the port number as well s the destination IP address (not all of them do), but if it does then you don't need to change anything on the server.

Need Help with Virtual Host

a quick Explaination of what I'm trying to do.
We have a DNS name, "our_intranet.com". This DNS points to a load balancer which routes the call to "our_weblogic_server:7015". When a request with this DNS comes in, we really want to go to our_weblogic_server:7015/portal/site/our_intranet. Can this be acheived using a Virtual Host? And if so, could give an example of creating a virtual host?
Thanks,
Tom.

Thank you James for your reply,
I do appreciate you taking a moment to respond and include some suggestions. At this point I feel 90% certain that the answer lies within WebLogic configuration somewhere.
Discoverer is a J2EE application as I understand it and based on that belief it is probably using the standard J2EE servlet API calls such as ServletRequest. getScheme() (the protocol portion of the URL such as http, https, ftp), ServletRequest.getHostname(), and ServletRequest.getPort(). Those API calls return values derived by the server either from the connection itself or from server configuration.
The URL's being returned by the web application are not static either. Although the protocol and the port never change (always http://...:80/) the server hostname does. If I add an entry to my host file for fred.somewhere.com and then hit the server using that server name then the URL's returned by the web application are http://fred.somewhere.com:80/, and if I use barney.somewhere.com I get a similar result. Now, the web application could be reading the "Host" HTTP header out of the request itself to derive that information but why go through all that trouble when the Servlet API gives you a standard way to do it.
For this reason I believe Discoverer (the web app causing our grief) is getting this information from WebLogic even though I cannot verify that with absolute certainty. I wish someone from the Disco area could verify that. I have had a support request open with Oracle for over a week but so far they haven't been able to tell me where they get that information from (which I'm sure is just because I'm not speaking with a developer). I may actually in fact pass on this question to the Discoverer forums you suggested. If someone can at least tell me if Discoverer is getting this information from the application server then I can at least pass that along as confirmation to WebLogic folks.
I have set up an Apache web server as a reverse proxy server for http and https in front of this particular server as an experiment and get similar results with the server name. Whether I hit Apache via http or https I always get back http://servername:80/ from the back-end WLS. The fact is WebLogic isn't even running on port 80 which makes it even more interesting why the URL's we get back should point at 80 instead of the port WLS is listenning on. Since there is no port or protocol information contained within the HTTP request sent by client browsers (only the Host header which just has the hostname) that may have something to do with why the server doesn't know how to provide correct values, but that doesn't explain why it would choose to tell the web application port 80 instead of the port it is actually listening on.
As far as tracking down how to configure this beast it might be complicated by the fact that I don't think this is just WebLogic Server. This is Fusion Middleware. I didn't think that included Apache HTTP Server, but actually I can see there is a directory for Apache on the server identified as ohs (stands for Oracle HTTP Server). Some of the help in Enterprise Manager (or maybe it was in the WebLogic administration web console) actually talks about Oracle HTTP Server which they say is based on Apache HTTP Server and in fact the configuration files are consistent with Apache. That doesn't mean I don't believe WebLogic folks like yourself that say Apache is not a part of WebLogic server (which seems like a pure Java application) but maybe it is a part of Oracle Fusion Middleware. They might just have it there for other stuff working together with WLS (such as Oracle Web Cache) or for load balancing as you mentioned. If it is there then it might either complicate things, or might provide a possible solution. If it really is running there in front of WLS and we can use some Apache configuration values to override URL information that the server passes on to the web applications maybe it could help. I did see some processes running on the same server with a name something like HTTPD.worker. My Apps DBA's (who are also learning as they go with WLS) said they did zero Apache configuration as part of the install however and I know zero about how (or if) Apache is working together with WLS.
I tried going down the path of setting up a custom Network Channel and Virtual Host because a) it seemed like a logical place to look and b) I had seen some references to them on the web but as I tried to step through the configuration I admit I never saw any settings that related to protocol overrides. I have seen host and port overrides somewhere along the way but never a protocol override.
I'm confused that this seems so complicated. I mean, aren't there a lot of people out there running their servers behind a hardware load balancer with SSL termination at the load balancer (it handles the https decryption and then forwards the requests unencrypted to the back-end servers)?
Your link to the "Corecoreserverserverprotocolshttptitle.html" looks like just the right place (almost). If it only had Frontend Port and Frontend Protocol as well as Frontend Host (and instead of Frontend HTTP Port and Frontend HTTPS Port). So frustrating to be so close but miss. I do appreciate the pointer though.
Funny that you should bring up the post on WebLogic Wonders because that is actually the example I tried to follow when I attempted to set up a network channel and virtual host. I aborted before the deploy because the deploy wasn't working quite how I expected and I had little confidence it was going to help me at that point (because I hadn't been presented with any setting that allowed me to override the protocol (http/https) value for a front-end system. I'm still not quite sure how the Network Channel works together with the server/domain/virtual host so perhaps I need to do a little more reading.
If anyone understands exactly what I am trying to achieve though and can give me some direction it would be much appreciated. It seems straight forward to me:
We have an F5 hardware load-balancer that runs here:
https://external-servername:443/....
It uses hardware SSL accelleration to decrypt the incoming request and if it sees /discoverer/ in the URL it then forwards the request unencrypted to a back-end WLS here:
http://internal-servername:8888/...
We would be happy if any connection that server recieved it always overrides the scheme (https instead of http), server (external instead of internal...it actually does this properly already), and port (443 instead of 80). In a perfect world it might behave differently if we connect internally directly to the server (in other words if we don't access it through the load balancer then it provides URL information to continue accessing it directly) but that is just icing on the cake which probably would require virtual host configuration to differentiate the two. We'd be ecstatic if we could simply override those values all the time for the entire server to some constant values that we set.
Thanks,
Eric R.

Help with OSX server mail setup

Please if anyone can tell me what I am doing wrong, I would be very grateful. I have a company with an externaly hosted website and an an internally hosted email (OSX server). I have everything kind of working, but some things don't seem quite right. I'll explain below:
I have a purchased domain: mycompany.com hosted by godaddy.
I am using Godaddy name servers: ns65.domaincontrol.com and ns66.domaincontrol.com
The external godaddy DNS has an a name entry for my mail server: mail pointing to 123.123.123.123 (which is my companies external static IP address).
There is also a null (@) a name record for my website hosting service (squarespace) pointing to 456.456.456.456
There is a cName record www pointing to the squarespace domain "www.squarespace6.com" (know this is unusual, but it is how squarespace asks this to be set up and does not work otherwise)
There is an MX record with priority 10 and host name @ pointing to mail.mycompany.com
I have a airport extreme router with the appropriate ports forwarded to the OSX server.
The DNS servers on the router are pointed to the internal IP address of the OSX server
I did not change the domain name on the router (mistake?) it is currently san.rr.com
On the OSX server I have set up host name to be mycompany.comDNS is set up with primary zone being mycompany.com
Primary Zone entries include
nameserver = mycompany.com
machine record host name is mycompany.com and the IP address is the internal IP address of the OSX server
another machine record with host name "mail" and IP address is the internal IP address of the OSX server.
Finally, there is a mail exchanger record with mail server "mail.mycompany.com" and priority 10
There are 2 entries autocreated in the Reverse zone
Mail is setup and running on the OSX server providing mail for "mail.mycompany.com"
Users are setup with email address: [email protected] (note: without the mail subdomain - I think this is OK?)
I am using self signed certificate.
In my clients (windows Thunderbird, Mac Mail, iOS mail), the settings are for the incoming mail server host name to be "mail.mycompany.com" and the outgoing also to be "mail.mycompany.com"
I woud have expected this to be imap.mycompany.com and smtp.mycompany.com respectively, but it doesn't work when I input these values and works with the former. Have I set this up wrong?? imap seems to require SSL on port 993 and SMTP seems to require TLS on port 587.Outlook on PC gives me an error that after googling appears to be a problem with not recognizing a fuly qualified hostname form the SMTP client. I see the fix, but wanted to know if that meant that my server didn't have a fully qualified host name and whether I should change that rather than just remove that restriction???
The final problem is that my outgoing emails seem to be getting caught up in other people's spam filters too frequently. What is the main reason for this? Is it because I have set something up wrong and it brings up flags or is it simply because I am not a huge hosting company, or somethign else althogether?
If you've gotten this far, big thanks! If you can help me, even more thanks!

Well, actually they are both getting caught up in spam filters and bounced back. I actually realized that part of the problem is that I have a dynamic IP address, but it doesn't change. Regardless, on the bounce back it looks like hotmail and other domains are rejecting email from my IP and recognize it as dynamic. This was a test server that i would by physically taking to my business where there is a static business IP address (Cox).
Sorry for the very long original message, but it seems that most people don't post enough information for the problem to be solved in their original posts and I was hoping to provide as much detail as possible.
The other is the question of "are things set up right?" It seems strange to me that both my outgoing and incoming servers are "mail.mycompany.com" and not imap.mycompany.com and smtp.mycompany.com and I wonder if this is going to cause me to have problems?
Is it a problem that my email addresses are [email protected] and not [email protected]?
Was I supposed to change the domain name on the router?
Also is it going to be a problem that I am using a self signed certificate?

Help with SQL Server 2005 http Endpoint

I am trying to use mx:webservice to directly connect to a SQL
Server 2005 HTTP Endpoint. Is this possible. Is there going to be a
problem with crossdomain issues? If the Endpoint is actively
listening on port 80 then IIS cannot. So I cannot place
crossdomain.xml in webserver, how will I overcome this crossdomain
problem? Am I making this more complicated than it is? If anyone
has an example it would be appreciated. All I want is a flex2 app
talking directly to sql server. Seems possible.

Kent, I see that many others have reported that error (doing
a google search), but I see no ready answers. I saw something that
reminded me of a connection string value that I've seen answer some
problems. May be worth a shot for you: try adding this string to
the connection string (in "advanced options") for your datasource:
AuthenticationMethod=Type2
If it doesn't solve it, remove it. But keep it handy in case
it ever may help with some other problem.
Here's one other possible answer for you:

Help with a server - crashed after update -SOLVED

Hi everybody.
at the school where I study,. its the student who´ll take cake of the network, and now we have a really big problem...
After an pacman -Syu, (by an older student) one of the servers crashe. Its the only one that´s been updatet. Its run f.i. Apache , stunnel and up against an LDap server.
The problem is that the only way you can get into it, is in single user mode. At normal boot at the login-menu - we could type in the username and passwd, but the machine is too long to validate the passwd so it times out. thats also when you trying to lock in as root. And we cant start Apache(Even though we selv compiled it, and not did a pacman on that one.) But I´m not into arch that much yet, so hoefully someone can give me a hint about what went wrong during the updates..
But the worst part about that one is, that everything goes by that one, so we cant get in på using ssh.. But after 7 hours trying and studying the net - we didn´t get anywhere. and we don´t have a clue what to do ...
looking in the logfiles do not show anything unusual....
in normalboot at the login screen, after ca. 40sek. the message comes :
The server died unexpectet... thats it
So please help with this one - if anyone have a clue what went wrong..

Heya,
have you tried using a knoppix-cd or another live-cd to have a look at the system or isn't that a possibility?
You can also login by adding the following kernelparameter: init=/bin/sh
However, I'm not sure how to mount the partitions then.
I'm guessing that the message "server died unexpectedly" is coming from a certain server-process (not the machine). Do you know which process and have you had a look at the logfiles (if there are any) of that process?
You can have a look at the output of the "dmesg"-command maybe if it is kernel-related (I think).
You say it isn't overridden. Are you sure? You can tell pacman to not override packages or certain files, but you have to mention it in the "/etc/pacman.conf"-file.
Hopes this helps you,
greetings,
Michel

Help with a server program

Hello,
I don't know much about threading, but I've got this server program (code follows). And where it does this... :
                    // Create a new thread for the connection
                    HandleAClient thread = new HandleAClient(connectToClient);
                    cn = clientNo;
                    // Start the new thread
                    thread.start();I need it to create another instance of the client program that accessing it with the same thread(I think, as i said I don't know much about threads). That way when a remote user accesses the client program, the server will automatically open another client program on the machine the server is running on. Then while their both using the same thread, they'll be able to speak back and forth without anyone else getting their text.
Does this make sense? Can anyone help?
Here is the server code, I don't have it perfected yet to send the text, but the clients will regester with the server.

Im working on a project for university, and one aspect of it is downloading files from a remote computer.
The majority of my project so far has been using RMI only, for browsing the remote computer, deleting files, renaming files, creating new directories and searching for files. All of this is done via a GUI client, with a server running on the server machine.
Ive now reached the part where I'll need to implement the downloading of files. I want the user to select a file from within the GUI and click download, and get it off the server.
I dont need any help with event handlers or getting the contents of the remote computer or anything of that sort.
Consider when I have the name of the file that I want to download from the client.
Im having trouble understanding how exactly its going to work. Ive seen examples of file transfer programs where the user types in the name of the file in the command line which they want to download. But my implementation will differ.
Every time the user clicks the button, I have to send to the server the name of a different file which will need to be downloaded.
I imagine in the event handler for the Download button I'll be creating a new socket and Streams for the download of the file that the user wants. But how am I to send to the client a dynamic file name each time when the user tries to download a different file?
I am a bit new at this, and Ive been searching on the forums for examples and Ive run through them, but I think my situation is a bit different.
Also, will RMI play any part in this? Or will it purely be just Socket and Streams?
I'll also develop an Upload button, but I imagine once I get the Download one going, the Upload one should be much harder.
Any ideas and help would be appreciated.

Hi
I'm no RMI expert... and I did not understand your question very well....
I think you should do this procedure:
you should send a request for the file from the client to the server . then a new connection between the two machines should be made which will be used to send the file.
by using UDP you will achive it quite nicely...
//socket - is your TCP socket you already use on the client...
//out - socket's output stream
byte [] b=new String("File HelloWorld.java").getBytes();
// you should use a different way for using this rather than using strings...
out.write(b);
DatagramSocket DS=new DatagramSocket(port);
DS.recieve(packet); //the data is written into the packet...on the server side you should...
//socket - is your TCP socket you already use on the server...
//in - socket's input stream
byte [] b=new byte[256];
out.read(b);
/*Here you check what file you need to send to the client*/
DatagramSocket DS=new DatagramSocket(server_port);
byte [] data=//you should read the file and translate it into bytes and build a packet with them
DS.send(packet); //the data is in the packet...This way the server sends the required file to the client .....
I hope it will help, otherwise try being clearier so I could help you...

URGENT HELP WITH VIRTUAL WLC

We had a problem with Virtual Machine which Cisco Virtual WLC installed. Virtual Machine files were damaged and the system was not start normally. We have had to reinstall the WLC, but after installation impossible to import current license to new one.
how can we install this licence again?

Licenses are tied to the device they're being used on. With a virtual WLC, the license is tied to the unique identifier of the vWLC and when you recreated the vWLC after your VMware problems the new vWLC has a different unique identifier.
It's a similar situation to what happens when a physical controller is faulty and is swapped out by cisco, the replacement will have a different serial number and you'd have to re-host the license to the new serial number.

Problem with virtual Server

We are trying to fix a problem where a URL is only supposed to be visible from the company intranet, not the internet as a whole.
We have created a virtual server on the same system that is listening on a different port (1443 instead of 443) . However despite various changes to the server.xml such as changing the docroot, disabling or removing WEBAPP entries etc, the server behaves exactly the same on port 1443 as it does on port 443.
If I could make it display ANYTHING differently it would be a start. Any assistance is appreciated.

Care to share your non-working server.xml file?

Please help with Forms server and forms

Hi, all
I am new to oracle.
Mine is home PC and the spec. of the system are as follows.
database:Oracle 8i EE
Forms :6i
OS :Windows 2000
Yesterday I downloaded Oracle9iAS Server and followed the documentation in installing.
As per the documentation, I accepted default values in many cases and went thru with installation.
At the end of the installation, i got the following config(found at the bottom of the message).
Please give me steps in resolving the issues below.
Also,
when I run the "Run form from web" from Programs....
what if the web listener port is taken. how do we figure out if one is already in use and if so what are other ports available to me.
and finally in the same app. is "Web Host" the name of my computer on which I installed the Oracle server?
TIA
Shankar

Thanks, Vikas!
But I did a search for 6iServer.conf and did NOT locate any such file
Please help
TIA
SHANKAR
Shankar,
It would have helped if you had indicated what is the full version of 9iAS that you have installed. By default the portnumber that is used is 7778.
As per the entries, they should have already been made in the config files. But check that the 6iServer.Conf file and it should contain the entries that you are being told to update. If not, then add the entries in the 6iServer.conf file and that is all you need.
HTH.

Help with Mail Server Setup/DynDNS

I don't have a static IP so I setup an account/registered a domain with DynDNS. The test site is hosted fine via Leopard Server. However, I am trying to setup a mail server to no avail. Configured Mail Server through the assistant and ended up with these settings: domain name - performa460.com hostname - mail.performa460.com POP, IMAP, and SMTP all enabled. Setup a user in workgroup manager and enabled mail. Still Cannot access mail through Mail.app and no users are listed on the Maintenance/Accounts pane. Obviously I'm new to this and need to be pointed in the right direction. Any help is apreciated; thanks!

DynDNS's base service won't work for you if you want to use your own full domain name unless you use their Custom DNS paid service. I'm assuming this is something you've already done. If so, you need to configure both the host name and the MX records for your domain to point to the right places. You'll need to set up DynDNS name servers through whatever domain registrar you use and then configure the CustomDNS service through DynDNS's web interface. Once you can successfully connect using a web browser, then look into your mail settings.
However, depending on what provider you're using for your broadband, you may have the mail ports blocked by your ISP and/or in your cablemodem/router. Be sure to open 25 and 587 and any other ports you intend to use.
Finally, you may find that even if you've configured everything correctly, other providers will refuse your mail as spam (google, yahoo, etc) because your IP address is on a "residential subnet" or because your forward and reverse DNS don't match. That means you'll need a mail reflector to bounce your mail off of with a proper IP. DynDNS has inbound and outbound mailhop services that you can use for an additional fee.
Bottom line is, because spambots inhabit a lot of dynamic IP blocks, you have to jump through a ton of hoops to get it working reliably.

Help with Test Server & Binding Recordset ASP-SQL

Using CS 3.3/DW. Behavior is the same on two different
machines. One is Vista Home Premium SP1 IIS 7 with 6 compatability,
other is XP SP 3 IIS 5.1, both have IE 7 and full SQL 2005 with
SP's.
Haven't gotten very far away from static page yet, because I
can't test. Have scoured forums and even talked to Adobe who
recreated the problem then told me that they hadn't done sufficient
testing to SQL 2005 prior to release, were supposed to call me
back, did once, supposed to call back again and haven't (3 days).
So I'm turning to the community for help, please.
Set up test server in folder 'TServer' under
C:\inetpub\wwwroot. Built a 'Hello World' ASP/VB Script page with
no data attached, tests fine, puts in the appropriate folder and
says "Hello World" in browser like a good little box should! Have
built many DSN's, they tested during the building fine, I've tried
various versions of ODBC and OLE DB, including but not limited to
Native SQL Client, which is my preference and have been quite
successful setting up the DSN's...they add to the ASP page/Site
(it's greyed out unless you have an open ASP page) fine. Test at
that point works fine. As soon as I bind a Recordset (whether I
have dropped data on the page or not...same 'Hello World' page with
Recordset info near the top of the code) and test, I error out.
Any thoughts? I'm sure you'll need more info...I've tried to
put as much as I can for starters. Thanks in advance.
Peter

When you say that you error out, what error are you getting?
