Server claiming its IP address is 127.0.0.1

I know I've seen this error in the past, but can't remember what we did about it.
Trying to connect to an RMI Server on a remote PC, the client uses its actual IP but the remote object stub returned claims and endpoint of 127.0.0.1, causing method calls on the stub to fail with a socket exception.
It only seems to occur on linux/unix based servers. Anyone familiar with this issue?
Thanks,
Mike

This entire forum is familiar with it. Try searching it for 127.0.0.1.

Why does RMI server sets its connection address?

I use RMI for several years now and it is really great. But what I did not understand all this time: why the server has to inject its own address to a client. I only see disadvantages of this behavior and this is a big pitfall to all newbies using RMI (two nics, different networks connecting to one server).
So my question is, what is the reason for this kind of design? Do I miss some essential security/network point?
Probably a proper callback mechanism might be one reason, but what else?
I don't need answers like it is all documented and it is easy. As I said I am used to it, but I believe it is not as easy as it sounds and it is hard to understand for a lot of people. I want to give you one example: We are developing and servicing products which are operated in closed private networks. For service and diagnostics we have to connect to these networks via VPN connections. In such cases it is hard to connect to the system applications because all the RMI servers insists on their own address/name which might be know only to the local network.
Thanks in advance for your attention

The registry and the server could be on different machines, so the client would know the address of the registry in order to lookup the remote object, but the registry would have to tell the client where the server is. That is, after all, the whole point of the registry!Ok I got this,
Also, there are facilities to give the client a different address to the servers actual address. This is used in cases where, for example, the server is behind a NAT firewall. The server will only be aware of its internal address, but clients beyond the firewall will need to use the server's external address to reach it, so the objects returned from the registry will need to have the server's external address embedded in them even if the server and the registry are running on the same machine.Ok, so you have to set this to a reachable address for all clients. But in general the client already knows this since it reached the server already. So I don't see the point the server should have to change this afterward.
However I still think only the first point is not enough to have so much hassle in all other environments. Do you know a way to override the registry or possibly the client registration to ignore what the server does say to it as the "real" address?

My Client Admin wants to access the server by its IP address using the web Browser

Dear All,
I am new admin.
I have created a Virtual Server and I have configured an IP address provided to me by the NW admin.
So now I have to request the NW admin to allow this IP to be remotely connected through remote desktop connection.
If this IP is allowed for the Remote Desktop connection then can I enter the same IP address in the Browser's address bar and access this virtual server on the
Local Network.
If Yes, then I am very happy to know this info.
If no, then please provide me steps to make this IP accessible through the browser's address bar (on the Local Network).
Please provide me necessary info as I have to make this task completed as Instructed by the client.
Best Regards,
Ahmed

Dear Sir,
Thanks for the reply and support.
My Question: Rather than opening the "Remote Desktop Connection", Can we directly enter the IP address of the server in the browser's address bar and login to
our server on the local network?
If we cannot login to the server by entering the IP address of the server in the browser address bar by this method, then what is the method to login to our server by entering the IP address in the browsers address bar.
Note: I just need to do it on the local network only.
Please show me how to do it.
Regards,
Ahmed
By enabling RDP, you are enabling remote access to the desktop where you can login and have a Windows Desktop. I have seen in another thread you created that you would like your developer to be able to administer a Website remotely. In this case, that is
something different. If you are using IIS then you need to check your Bindings and make sure that you do have an administration portal that you can access to make changes remotely.

How do I have a cRIO register its IP address with the DNS server, clearing any previous entries?

I've run into a problem when I try to move a cRIO-9073 from one network segment to another (say 10.1.33.x to 10.1.36.x): The old IP address remains registered on our DNS server, so trying to access the cRIO by its DNS name fails as the DNS server tells my PC to look for the old IP address.
When I search the DNS server from my PC using "NSLOOKUP" with the old IP address, it finds the DNS name of the device. If I repeat the search with the new IP address (MAX finds the device with its new address, but I hate to have users use MAX to find it), it again returns the DNS name, so it appears the DNS name is registered under two IP addresses on our DNS server. I've also repeatedly tried to flush my PC's DNS cache using command "IPCONFIG /FLUSHDNS", but it still tries the old IP address. I also see in MAX that the cRIO is using the same DNS server my PC uses.
Our IT people say that I have to tell the device to re-register its DNS name. They told me a command to do it from Windows (command "ipconfig /registerdns"), but obviously this is VxWorks on the cRIO. Is there a command to do this on the cRIO or a setting in the "NI-RT.INI" file I can change? I honestly don't think this is the issue (as it successfully registered the new IP address under its name), but I want to try it if it's possible.
Thanks!
Erik
ps - Our IT dept. won't let me use static IPs unless I get them assigned by both their MAC address AND the network jack they're connected to, so that's out.

Normally this is actually a function of your DNS server. It needs to perform a periodic flush of stale records. You can check the RFC for the DNS protocol and build the necessary packet yourself.

How can a client lie about its IP address to the server (HTTP)

I'm trying to set the user agent property to other than Java/1.4.2_02, and also send requests to the server that should appear coming from ip specified by me. In another words i am trying that I could hit the server with variety of different setting of user-agent and ip address. I have this piece of code that works fine for the user-agent. But how can I send request to the server mimicking different ip addresses. Any ideas?thanks
I don't to download the page. I just have to send the requests.
Here is the code that sends different user-agent configurations to the server:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import javax.swing.text.html.HTMLDocument;
public class teste {
private static HttpURLConnection conn = null;
private static URL url = null;
private static HTMLDocument html = new HTMLDocument();
public static void main(String args[]) {
BufferedReader in = null;
String str = "";
try {
url = new URL("http://www.google.com/search?hl=de&ie=ISO-8859-1&q=test");
} catch(MalformedURLException e) {
System.out.println(e);
System.exit(-1);
try {
conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7.2) Gecko/20040803");
conn.connect();
in = new BufferedReader(new InputStreamReader(url.openStream()));
} catch(IOException e) {
System.out.println(e);
System.exit(-1);
}

There is bad news, and their is worse news.
You need raw sockets. Java doesn't do raw sockets.
Windows doesn't eithier (XP SP2), though there ARE ways arround it, the problem is you will need to be administrator and it will be throttled (read SLOW) by the OS itself (no way arround this) and it will refuse to send Spoofed IPs (no sensible way arround this).
Linux you need to be root.
You need to write a JNI that will drop your requests onto the network.
It's horrible, and you need to consider whether java is the right language for this. Sounds like you are just doing some NATting or proxying or such, which would be much easier to do in pure c. Unfortunately I have to have raw packets from java so pain and suffering for me.

Why is Mail asking me for the name of an smtp server for an email address that doesn't exist?

I've migrated from Snow Leopard to Mountain Lion on a new Mac, but in trying to use Mail on ML, it keeps asking me for the name of an smtp server for an email address that's never existed. The addy has my user name correct, but the server part of the address doesn't exist, or at least I've never used an email address with that provider. On ML there's no plist file for Mail, so nothing to delete there. What else can I do to get Mail working? The only other option I have is to abandon Mail as being crippled and useless, and use Postbox, which for it's price (US$9.95) is an attractive option. OTOH, I've paid for Mail after all, so it really ought to work. Any clues as to what I can do to stop its nonsensical behaviour? How do I file a bug report?
TIA.

Error starting HTTP-Server: Cannot assign requested address: JVM_Bind

Hi.
Anyone know how to configure the Oracle HTTP server within Jdeveloper9i to work?
When I try run a JSP page, I get the following error:
C:\Oracle9iDS\jdk\bin\javaw.exe -ojvm -classpath C:\Oracle9iDS\j2ee\home\oc4j.jar com.evermind.server.OC4JServer -config C:\Oracle9iDS\jdev\system\oc4j-config\server.xml

cheers paul

A JVM_Bind error means that the port is already in use. This is an unusual error message to get because JDev scans the ports ahead of time to make sure they are free before launching the server.
Check if you have any processes running that might be holding port 8888. There might be a previous instance of the OC4J server running that hasn't released port 8888 yet. On Windows, at a command prompt, you can use "netstat -a" to see local ports that are in use.

Debugging WL Server when its an NT Service ...

Is it possible to debug WL Server via a JPDA debugger (such as Kamira
Bugseeker) when WL Server is running as an NT Service? Are there
recommended changes to the cmdLine parameter in installNtService.cmd (its in
the samples)?
I've tried supplying command line parms

in the Service / <my name > / Parameters / cmdLine registry entry but it
seems to take FOREVER to come up. Any clues?

No entries at all about this in
D:\bea\wlserver6.0sp1\config\energizer\logs\weblogic.log or
D:\bea\wlserver6.0sp1\config\energizer\logs\access.log
Nothing in NT Event Log either.

Could this be a command-line length limitation of some sort?

This means that your Mac is not seeing your WinBox, either by IP address (a series of four sets of three numbers which might look something like this: 192.168.001.010) or by name (usually a SMB connection, which would look something like this: 'smb://winboxname' where 'winboxname' is the name of your WinBox).
Typically this means that you were connected by IP, and the target's IP address has changed.

You probably have DHCP enabled on your home net, and your WnBox's IP address has changed because its old lease expired. That kind of thing is why you should set up your net to either have fixed IP addresses or to reserve a specific IP for a specific machine, or you should use the smb name instead of the IP.
I don't understand why this message suddenly appeared keeping me from accessing the shared folder on my XP based computer.
See above. If you want to connect by IP address, you'll need to know the WinBox's IP. Go to your Start menu, select the 'Run' box, type 'cmd', hit Enter. You'll get the Windows terminal. In the terminal type 'ipconfig/all'. You'll see the IP address (and the MAC address, useful if you want to set up a reserved IP address). Ensure that the Mac is connecting to that IP. (enter 'smb://theIP' in the network connection box.)
If you want to connect by name, you'll need to know the WinBox's name. Right-click on 'my computer', select 'properties'. Click on the 'computer name' tab. There it is. Use 'smb://computername' in the network connection box.
Thanks

How can I force a DHCP client to renew its IP address??

Hi to all,
I have installed in a customer, a Cisco 2801 who has configured a DHCP pool. This router takes a reload every month (by maintenance purposes), when it is up (in the network we have AVAYA phones working fine, it's a call center), this phones takes a reload to renew the ip, which is assigned by the DHCP pool.
The problem is when some phones try to renew its IP address (after the router reload), the phone detects a IP conflict an it forces a reload. This reload normally is in production hours, the agents lose their phones and they can't work......
There is some option to force the DHCP client to do a IP renewal from the DHCP server???
Thanks to all.
Regards.
David.

First of all you should investigate what is going so horribly wrong in your network that you have to reload your router every month (and even worse in production hour). If it's an instability, have you tried to update to a newer IOS-version?
Regarding your DHCP-problem. For that you just have to configure your DHCP-server correctly by specifying a database-agent:
http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_dhcp/configuration/12-4t/dhcp-12-4t-book/config-dhcp-server.html#GUID-5F022CF5-671E-49E7-8FBD-69997EEBC730
With this function the router stores all bindings and knows (also after a reload) which addresses are already assigned to which system.

Unable to send email from my server to internet mail address. Labview.

But when I try to send from my server to some other email address I get an unable to relay "email address" server response. If someone has any ideas on this I would appreciate it. I have included some information that may aid in this endeavor. (I do not want to use Active X thanks to Outlook's dislike of that)

I agree, it is ususual for an SMTP server to check the validity of the reverse-path address, because mailers could just use a invalid address on a valid domain, e.g. [email protected] The address in the "MAIL FROM:" command gives the reverse path to communicate errors and can be different from the actual sender address.
In any case, this is quite irrelevant for the current discussion, because address verification has nothing to do with relaying.
The error message:
550 5.7.1 Unable to relay for [email protected]
is completely unrelated to your:
450 Unable to find nowhere.com
Just to clarify, I was talking about address in the FROM: field of the message header, and not what is
communicated in the "MAIL FROM:" SMTP command. (Similarly, the TO: field in the header is not used for message targeting and can be anything, it can even be missing and the SMTP server still does not care. Targeting is done entirely with the RCPT TO: SMTP command which not contained in the header (the mail header is part of the message DATA). Refer to RFC 821 for further details.
You probably won't find a legitimate SMTP server that allows relaying, so the solution is to use the designated SMTP server for the particular location.

'"Connection Failed" : The server "rrnas01" may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again' message

'"Connection Failed" : The server "rrnas01" may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again' message keeps displaying whenever I try to open any Adobe CS5 applications (except for Adobe Acrobat Pro). It displays until I click "OK" about 15-20 times or so and then will finally let my program open.
I have tried deleting files within my Library/Preferences folder and turning off/deleting login items within my system preferences as other forums suggested but nothing happened. Spending 3.5 hours on the phone with Adobe and completely uninstalling and then reinstalling the entire CS5 Master Collection didn't work either.
Also, it may be helpful to know that my programs worked fine for about three weeks then when we got internet and changed the password (the join, not the adminstrative password) with the wireless network "ScubaSteve" (which I've used with no problems at my old apartment) it started acting up. I have never seen "rrnas01" before so I don't know at all where it came from. I also installed the free 30 day trial of Suitcase Fusion 3 recently, but thinking that could also be the cause I have uninstalled it, and still no help.
Please help me! And please keep in mind I don't know all the computer lingo that a lot of the people in these forums seem to know. Thanks in advance for ny help you can give me.

It may not be possible .. there is a major bug between Mountain Lion and the TC where the TC disk goes off the radar of the computer.
Lion is also affected but not as badly.
7.6.4 seems worse than earlier firmware.. so back to 7.6.1 or 7.5.2 if that is possible.
Obviously that is not a solution for a later Gen5 TC.
Reset to factory after the firmware downgrade. .use all network names that are short, no spaces and pure alphanumeric.
If the TC is the main router set the dhcp to a very short lease time.. eg 30min.. and see how it goes, or try a longer lease like 99days.
I prefer the very short lease but response has been mixed.
Use ethernet not wireless.. ethernet is always more reliable and stable than wireless.
And last .. a nightly electric timer that powers off every night at midnight for 1min.. would not be the first device we have suggested a fix that amounts to beat the unit to the punch by forcing it to reboot since it is unstable.

My MacBook is self-assigning its IP address (and won't let it go)

My MacBook is generally well-behaved, but at times (seemingly random times), it self-assigns an IP address when it should be getting one from a router. The problem is sporadic and occurs in two separate locations - home (where I have control of the wireless router) and school (where I have no control over the router).
Sometimes I come home from school, and I have no problem connecting to my WLAN (2Wire router). Sometimes, however, I get the dreaded "self-assigned IP address" message, and I cannot thereafter get an "un-self-assigned" IP address. I have tried renewing the DHCP lease - no luck. I have tried trashing com.apple.airport.preferences.plist, and although that has worked on occasion, usually it doesn't solve the problem. Even more maddening is that rebooting doesn't help. Nothing consistently solves the problem - and that is so much more annoying than the problem itself!
At school I have this same problem and more. The school network SSID is not broadcast, so AirPort seems not to be able to remember it. Every single time, despite the fact that I've asked it to "remember this network," I have to type in the SSID and WEP in order to join the network. Sometimes it works quickly, and sometimes it won't work for a while, and other times it self-assigns an IP address. (ARGH!) And then I have to try the hit-and-miss "solutions" that work sporadically at home, which work equally unreliably at school.
Can I make it STOP self-assigning an IP address when it thinks it can't get one from the network? Part of the problem seems to be that the AirPort does not to want to give up its IP address after it has self-assigned. Is there an equivalent to the DOS command ipconfig /release that I could type from a terminal window? (It has been a while since I used UNIX.)
There are many things I like about my new Mac (I was a UNIX user in grad school and then had to use a PC at work, so I am a newbie to Mac OS), but this problem is totally unacceptable for a computer that is supposed to be so much better than a Windows-based machine. At least in Windows I knew how to troubleshoot problems - here I am completely helpless! And I CANNOT believe Apple has not fixed this, because from what I can tell by looking on the web (when I can actually get a real IP address), people have had the problem for at least FOUR YEARS!!!!!!
Please help - I am desperate! Thank you in advance.

Have you tried making a New Location for each yet? The Automatic one get confused easily.
Some "nix" to try when it happens also...
sudo ipconfig set en1 BOOTP;sudo ipconfig set en1 DHCP
sudo ifconfig en1 down;sudo ifconfig en1 up
Sometimes having an all OFF Location can help, thanks to Gnarlodious...
