How to detect remote (client) host name or remote host address?

Hello!
I need to receive remote host name or remote IP address in the BSP controller DO_REQUEST method. How to do it?
In Java I can use getRemoteAddr() or getRemoteHost() methods of HttpServletRequest class. But in the BSP I can not find analogues of these methods.
Please help
Best regards,
Eugeny

Hi,
I guess there is something "cleaner", but here is a solution:
DATA l_host TYPE string.
l_host = me->request->if_http_entity~get_header_field( '~remote_addr' ).

Get Client Host Name

Dear Experts,
I am using
String ipAddress = WDProtocolAdapter.getProtocolAdapter().getRequestObject().getClientHostAddress();
retrieve client ip address.
When I use getClientHostName(), it still present client ip address.
Regarding the client hostname, how do I get it?
thank you.
Regards,
Weng

Use this
String hostName = WDProtocolAdapter.getProtocolAdapter().
getRequestObject().getClientHostName();
You also have one more method to get IP address.
String Address = WDProtocolAdapter.getProtocolAdapter().
getRequestObject().getClientHostAddress() ;

Open LMS Session from client host

Dear all,
i have a LMS application installed on a server X, the campus manager version is 3.2.
the application version is pretty old, but it is just working fine.
LMS is opening normally from the server itself.
My problem is that if i try to open Campus Manager/Topology services from a host different than the server itself a java screen opens mentioning trying to connect to ani server, and it just freeze and do not proceed. if i reopen from the server itself it works fine.
the server and the client host are on the same vlan, so no network access limitation exists.
Note: When i open the http request on LMS server from the client side, i authenticate and enter to the app normally but if i try to open the topology services or path analysis it do not proceed.
While checking the logs i found that it is like denying the Client Host name or IP Address.
please find log attached.

Dear Afroj,
Concerning the above mentioned debug steps; i don't find the option in the sequence on my server.
Point 1)      I can find LMSHomeScreen --> ServerConfiguration --> Setup --> ANI ServerAdmin --> DebuggingOptions
Point 2) & 3) I Select "Enable tracing on the selected modules". From the drop down list i check the "Trace enable" check box for the Module "topo".
       On the same page down, i check the "Record trace messages in log file", i enter the name and the path for the log file, C:\ANI_Debug
       And i press apply,
Point 4) & 5) From here i am not able to continue, there is no button to start debug nor under LMSHomeScreen --> ServerConfiguration --> Setup --> ANI Server        Admin --> Debugging Options nor under LMSHomeScreen --> Campus Manager --> Topology Services
There no path Campus Manager --> Admin
Point 6) How to run a new data collection?!
Point 7) if i enable "debugging" of java from control panel and i select to "show" java console, how to view Java Logs?
Thank you for your help

Getting host name and IP address

I have develop different types of forms which resides on server and clients are acessing it.Now from my end i want to track that which user is accessing my forms on the server i.e i want to know the client IP address and host name.When the user execute some query on the database then i will get it easily using sys_context function but if it perform some functions within the form and i catch the host name then it returns the server host name where the actual forms resides not the client host name and i want to know the client host name and IP address who is running the forms.Plz let me know the way so i can do that easily .
thanks

DHCP Client does not send host name to DHCP Server

Hello,
I installed Solaris 10 on VirtualBox and I cannot ping/ssh/telnet the virtual machine by its host name (even from the host computer) but only by it's ip.
I tried everything I could find on internet with no success (I don't want to add the hostname in every hosts file on every computer because it's not really professionnal)
I followed what said here: http://docs.oracle.com/cd/E26505_01/html/E27061/eyhuv.html#scrolltoc
Can someone has an idea of what I can do or why this does not work.
I installed a virtual Windows7 and an Ubuntu, and it worked perfectly.
Any help would be grantly appreciated.

During the Solaris installation process, you told it what the hostname was going to be and that you wanted that environment to exist with a dynamic IP address instead of a specific address that you desired.
When Solaris boots it broadcasts that hostname and waits for a DHCP server to be quasi-intelligent enough to award an IP address based upon a pre-configured list inside that DHCP server.   Hostname ABC would always get IP address 123 on subnet rst, hostname DEF would always get IP address 456 on subnet xyz, and so on and so on.
That's the fundamental process for proper (and thus secure) DHCP.
All your other environments (Windows, Debian, Ubuntu) are what might be thought of as "hacked for convenience" to get around that sort of network configuration. They take the lazy way to exist. That partial networking setup is good enough for a home network but would be miserably insecure in a corporate environment. Those choices are operating environments that are nice for end-user desktops but aren't Enterprise Class.
My suggestion?
Review the IP address range in your Netgear router's setup.
It is likely something like 192.169.0.1 through 192.168.0.50 and can be customized.
You probably don't have 50 devices on your network and probably will never have 50 simultaneous devices on your network.
... just do a reconfigure reboot and set your Solaris to use a static IP of 192.068.0.45
Then reboot and I predict your issue that prompted this forum thread will be gone.
That's how I've done it at home for many years, even when installing Solaris to bare metal (no virtualization).

Macbook Pro showing old name in DHCP Client List

When I originally set up my macbook pro, I gave it a name, we will say 'X'. Since then, I've changed the name to 'Y', however whenever I connect to a wireless access point, if I login to the access point and list the clients, it shows 'X' as my host name. What I have tried:
System Preferences->Sharing and entered the new computers name
Sysem Preferences->Network->Wi-Fi, clicked Advanced and set a Client ID under TCP/IP as well as changed my Netbios name under WINS
I'm at a loss as to why 'X' keeps showing up as the client ID on wireless access points after I've changed it on the system. There must be another location where that is stored.
Short of doing a full file scan for 'X', does anyone have any idea where else I can look and change this on the macbook pro?
Thanks!

Power cycle your dhcp server (router). The dhcp protocol retains ip address and computer information for reassignment to the same device whenever possible. Force the router dhcp router to reconnect and reissue a dhcp address by power cycling the router.

Why won't my host name appear on belkin router client list

Connection to router (Belkin N1 Vision) is good and mac address is displayed ok but client name is shown as 'unknown'. I have entered a name in the DHCP clients name box and renewed the lease, but to no avail.
All other conections including HP printer, iphones, tv's PC's, even belkin powerline adaptors show their correct host names but not my 2 MAC book pros both running OS X 10.6.8. Has anyone else come accross this issue?
Many thanks

If it's working on that new network, then it's unlocked. But you should use a valid SIM card of the proper size. Get another, correct one from the carrier.

Hello All,
we have created shared folder on multiple client machine in domain environment on different 2 OS like-XP,Vista, etc.
from some day's When we facing problem when we are access from host name that shared folder is accessible but same time same computer when we are trying to access the share folder with IP it asking for credentials i have type again and again
correct credential but unable to access that. If i re-share the folder then we are access it but when we are restarted the system then same problem is occurring.
I have checked IP,DNS,Gateway and more each & everything is well.
Pls suggest us.
Pankaj Kumar

Hi,
According to your description, my understanding is that the same shared folder can be accessed by name, but can’t be accessed be IP address and asks for credentials.
Please try to enable the option below on the device which has shared folder:
Besides, check the Advanced Shring settings of shared folder and confrim that if there is any limitation settings.

UNABLE TO RETRIEVE THE CLIENT IP ADDRESS AND HOST NAME OF A PORTAL USER

I'm trying to retrive the client IP address and host name of a portal user
trying to access a portal page using APIs:
PortletRenderRequest portletRequest =
(PortletRenderRequest)request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
HttpServletRequest servletRequest =
(HttpServletRequest)portletRequest.getAttribute(HttpCommonConstants.SERVLET_REQUEST);
String l_szClientIPAddress = servletRequest.getRemoteAddr();
String l_szClientHost = servletRequest.getRemoteHost();
but i found that for all portal users on different machines IP addresses, the
returned IP is the same for all which is Portal middle tier IP address.
So how can retrive the IP addess of a portal user trying to access a portal
page ?

Brijesh,
Do you mean how to see hostname/ip address of client requests processed by the server? If yes, depending on what's your front ending component - Web Cache or OHS, you can configure the access log format to have this information recorded in either of these component's access log file.
For Web Cache access log file, refer this:
http://download.oracle.com/docs/cd/B14099_19/caching.1012/b14046/diagnostics.htm#sthref2090
For OHS access log file, refer this:
http://download.oracle.com/docs/cd/B14099_19/web.1012/b14007/servlog.htm#sthref439
By default, both Web Cache and OHS are configured to use Common Log Format (CLF) that does record hostname/ip address so if you haven't made any changes to log format, this info is already there for you. Look for $ORACLE_HOME/webcache/logs/access_log file for Web Cache and $ORACLE_HOME/Apache/Apache/logs/access_log file for OHS.
Thanks

How to find the host name of a client?

Iam doing a project in grid computing. I have developed a client-server program. In that program I have to get the host name of the connected client. Can anyone tell me the code to do that?

Its the .getInetAddress().getHostName().getPort() methods...
Good Luck.

Can I send DHCP host name to my ISP from RV220W?

My ISP waits a definite host name from me to return my white IP address via DHCP. Can I set this parameter in RV220W router? I don't find such parameter in IPv4 WAN configuration page.

After firmware update to 1.0.3.5 I can set up router name but provider support answer that router doesn't send its name to provider during DHCP handshake. Is that right?

Is it not IPv6 by any chance?It is. And if I remember correctly, then "0:0:0:0:0:0:0:1" (or "::1" for short) is the IPv6-equivalent to "127.0.0.1", i.e. it's the loopback device.

Host name not showing up under Active Clients

When I go into my router and check active connections, I can see all host names like "Acer Laptop", "IPhone" etc..., IP and MAC address' that are connected to router. Today, when I was in there looking, I saw an asterisk where host name should be for the TouchPad. (it took me a while to figure out it was the TouchPad) Is there a reason why Host name would not show up?
I have gone into "Device Settings" and set "Name" as "Chucks TouchPad". Is that the host name that should be showing on router?
Thank You for any assistance.
Post relates to: HP TouchPad (WiFi)

Sure is, but it will involve some commandline work. First, you're going to need to install the SDK. You only need the Novacom part of the SDK, but AFAIK there's no seperate download for Windows... you have to get the whole thing. The SDK is available here: https://developer.palm.com/content/resources/develop/sdk_pdk_download.html
Next, you're going to need to enable Developer mode on your TouchPad, here's how to do that:
Start a Just Type search and enter webos20090606
A Developer Mode icon will display, tap it
Tap the toggle switch to turn it On
Leave the password blank and tap Sumbit
Close the Developer Mode app
Now, connect your TouchPad to your computer. Next, you're going to find a file called Novaterm.bat. It's buried in the install directory of the SDK. I don't remember the exact path (I don't use Windows anymore) but it's something like C:\Program Files\Palm SDK\Current\bin (keep digging around for bin folders in the C:\Program Files\Palm SDK path and you'll find it eventually). Doubleclick that to start a nice little terminal app. Choose your TouchPad from the drop down list and click connect.
Now, time for some command line stuff. Run the following commands in the terminal:
mount -o remount,rw /
cd /etc/dhcp
vi dhclient.conf
Press the I key on your keyboard to go into edit mode (this is a Vi specific thing)
Remove the # at the beginning of line 14 and change the andare.fugue.com inside the quotes to whatever you want your TouchPad reporting as. For example: #send host-name "andare.fugue.com"; would become send host-name "RidiusTouchPad";
To save your changes, hit the ESC key (to exit edit mode), then type :wq and hit enter. Note there is a colon in there. Again, this is Vi specific stuff.
sync
mount -o remount,ro /
Once you've done this, disable and re-enable your Wi-Fi and your TouchPad should be reporting a hostname. Kind of a lot of work if you ask me (unless you already have the SDK installed).
