Login to Oracle 8i Server from a remote location.
Hi Experts,
I wish to connect to Oracle 8i Server at Site 1 from Site 2.
Situation
Site 1 - Oracle 8i on Win 2K. This is behind a firewall FW1. Is in Win NT Domain1.
Site 2 - Oracle 8i Client on Win 98. This is also behind (a separate) firewall FW2. Is in Win NT Domain2. There is no oracle instance running at Site 2.
Also -
a. There is a secure VPN between Site 1 and 2 (through separate Firewalls. one at each site).
b. Site 1 and Site 2 use different set of IP-Address and also different set of Subnet Mask.
c. Both, the Client at Site 2 & Oracle 8i Server at Site 1, are able to ping each other successfully.
d. As there is no oracle database at Site 2, a Database Link cannot be created.
At Site 2, I have tried the following -
1. Installed Oracle 8i Client.
Configured the tnsnames.ora file.
The Port used is 1521.
Tried to connect from SQL*Plus but do not connect.
2. Installed development version of Oracle Forms 6i (surely after removing Oracle 8i client).
This also installs SQL*Plus.
Configured the tnsnames.ora file.
The Port used is 1521.
Tried to connect from SQL*Plus but do not connect.
Tried to connect from Oracle Forms 6i but login fails.
However, other Win98 clients (of Win NT Domain1) at Site 1 use the same settings of tnsnames.ora file to connect to the Oracle 8i Server.
3. Changed the IP address (of Win98 client at Site 2) to become a member of Win NT domain1 (same domain as that of Oracle 8i Server).
Repeated the above steps 1 & 2 but login still fails.
What more needs to be done?
Thanks in Advance.

Hi Fredrik,
You r right. But I have its entry in tnsnames.ora file. The entry looks like this -
My_Service_Name.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(COMMUNITY = tcp.world)
(PROTOCOL = TCP)
(Server = Computer_Name_of_Server_having_Ora8i)
(Host = IP_Add_of_Server_having_Ora8i)
(Port = 1521)
(Pipe = ORAPIPE)
(CONNECT_DATA = (SID = ORCL)
The same entry exists in the tnsnames.ora file on the local PCs (same office where the Oracle 8i Server is present) at Site 1 and these PCs connect the server without any problem.
Thanks

I need helping configuring RDP access to my local server from a remote location on my Cisco ASA 5505 Firewall.
I have attempted to configure rdp access but it does not seem to be working for me Could I please ask someone to help me modify my current configuration to allow this? Please do step by step as I could use all the help I could get.
I need to allow the following IP addresses to have RDP access to my server:
66.237.238.193-66.237.238.222
69.195.249.177-69.195.249.190
69.65.80.240-69.65.80.249
My external WAN server info is - 99.89.69.333
The internal IP address of my server is - 192.168.6.2
The other server shows up as 99.89.69.334 but is working fine.
I already added one server for Static route and RDP but when I try to put in same commands it doesnt allow me to for this new one. Please take a look at my configuration file and give me the commands i need in order to put this through. Also please tell me if there are any bad/conflicting entries.
THE FOLLOWING IS MY CONFIGURATION FILE
Also I have modified IP information so that its not the ACTUAL ip info for my server/network etc... lol for security reasons of course
Also the bolded lines are the modifications I made but that arent working.

ciscoasa(config-network)#Unclear what did not work. In your original post you include said some commands were added but don't work:
static (inside,outside) tcp interface 3389 192.168.6.2 3389 netmask 255.255.255.255
and later you state you add another command that gets an error:
static (inside,outside) tcp 99.89.69.333 3389 192.168.6.2 3389 netmask 255.255.255.255
You also stated that 99.89.69.333 (actually 99.89.69.233, guessing from the rest of your config and other posts) is your WAN IP address.
The first static statement matches Cisco's documentation, which states that a static statement must use the 'interface' directive when you are trying to do static PAT utilizing the IP address of the interface. Since 99.89.69.333 is the assigned IP address of your WAN interface, that may explain why the second statement fails.
Any reason why you are using static PAT (including the port number 3389) instead of just skipping that directive? Static PAT usually makes sense when you need to change the TCP port number. In your example, you are not changing the TCP port 3389. -

Connect to Sybase SQL Anywhere from a remote location.
BH
Hi, we are running SQL Anywhere 16. Currently our client computers are connecting through ODBC. Is there a way to connect to our server from a Remote Location (over the internet)? If yes, how?
Thanks
AronHi Aron,
Is there a way to connect to our server from a Remote Location (over the internet)?
Yes, there is.
If yes, how?
You will need to supply a HOSTNAME (or direct IP) and PORT to the server running the network database server, communicating over TCP (Note: This may involve opening a TCP port on your firewall to provide a direct TCP route). For the SQL Anywhere client, this information can be set in the ODBC DSN entry as the following screenshot shows:
Note that this is unencrypted traffic across TCP/IP, by default.
If this communication is over the Internet, using an unencrypted channel directly to the database is not recommended. Instead, we would recommend that you also configure Transport Layer Security (TLS) with strong encryption enabled using a certificate (either self-signed or provided by a Certificate Authority (CA)). To do this, you need to create the certificates and then start the SQL Anywhere database server with the (private) server-side identity certificate.
Once the database server is started, you will then need to configure the client for secure communication with the public certificate. When configuring Transport Layer Security on the ODBC client, the security settings (e.g. trusted_certificates, certificate_unit, certificate_company, certificate_name) can be entered on the "Network" tab:

Query a List of Open WMI connections on a server from a remote system
We are monitoring a specific windows service on a server using Sitescope remote monitoring. The sitescope system uses a WMI method to Check if the service on a specific server is up or not. Initially it works like a charm but over time the WMI connections from
sitescope time out and we have been told that Sitescope is not closing the WMI connection it opens gracefully and the open connections pile up.
I am looking for a way to list open WMI connections to a specific service and/or server from a remote system and a way to kill those connections via a scheduled PowerShell (or batch/perl) script. I was able to list specific classes by -list parameter
of the Get-WmiObject cmdlet
but am unable to determine which class will give me the information that I require and the method to kill those connections.Sitescope is not closing the WMI connection it opens gracefully and the open connections pile up.
1. It's not clear what "not closing the WMI connection it opens gracefully" means. WMI is a management technology that uses DCOM to connect to remote computers. (Is it really a question about DCOM?)
2. It's not clear what specifically "open connections pile up" means and what problem(s) it causes.
3. This is really a support question for that software's developer, not a question about WMI.

Invoking a Crystal Report stored on a BOXI3.1 server from a remote web page
We would like to run Crystal Reports stored on our BOXI 3.1 server directly from an in-house intranet website written in ASP.Net. Is there a recommended way of achieving this?
Some possible options we are considering are:
1) A pop-up window opens with InfoView loaded and showing the correct report already open. The user would then populate the parameters and submit the report as if they had logged into InfoView and navigated to the report themselves.
2) We write our own BOXI Crystal Report submission page in ASP.Net. This page would call the BusinessObjects Enterprise .NET SDK to retrieve the report parameter information and submit the report. This page would need to support Static, Dynamic, and Cascading report parameters.
3) Use some sort of 3rd party or SAP imbedded Web Component that we can place on our intranet site that interfaces with the BOXI server and supports parameter setting and report submission. This Component would allow users to specify Static, Dynamic, or Cascading report parameters.
Ideally we would prefer option 3 as this would be simplest to implement, however Iu2019m not sure such a component exists.
Do SAP have a recommended solution for invoking a Crystal Report stored on a BOXI 3.1 server from a remote web page?
Regards,

Business Objects Version XI R3.1
SQL ServerHi Paul,
there are several options:
- you could open InfoView via URL and the user navigates to the report
- you could create you own application
but the easiest way is an application called OpenDocument that is available out of the box which allows you to pass in several URL parameter and in that way you could open up the report.
when you go to help.sap.com and go to the BusinessObjects area search for OpenDocument and you will find the documentation with the details.

Accessing Computers Connected to a Time Capsule From a Remote Location
I am already able to access my Time Capsule from a Remote Location and have read/write access to the internal hard drive within the Time Capsule and the USB hard drive connected to it.
My problem is that I cannot access any shared computers or networked hard drives attached to the Time Capsule.
Suggestions are greatly appreciated.If you don't want to use Back to my Mac, you can just use screen sharing. Go into Airport Utility and go the Advanced tab along the top. Then click on port mapping. Set up a new port map to route to the iMac. When I did this, I just used the "Apple Remote Desktop" option from the drop-down menu, this pre-fills everything in for you except for the IP address of the iMac. Just pop the IP address in the field, save the new port map, and Update the TC. Now you should be able to screen share from anywhere with your MacBook Pro using the screen sharing app. The Screen Sharing app is located in /System/Library/CoreServices/ScreenSharing just drag it to the dock to keep it there. When you open it up it will ask you for a host address, just type in the IP address of your time capsule followed by the 5900 port number, for example x.x.x.x:5900 where x.x.x.x is the TC IP address.
Just make sure your iMac is set up for File Sharing, Screen Sharing, and Remote Login, and you should be good to go. Just a word of caution, when the port map is set up, anyone can use it, so set up a good password on your iMac. Also, under the screen sharing pane, click on "Computer Settings" and check both boxes and enter a password in the box. You should not need this because when you try to connect with your MBP, it should give you an option for logging in as an authorized user, in which case just use login info for a user on the iMac.
Just one last thing, if you close the Screen Sharing app and open terminal and enter:
defaults write com.apple.ScreenSharing ShowBonjourBrowser_Debug 1
then hit enter and reopen Screen Sharing, it should give you a list with all your bonjour computers and saved computers, so when you out in your IP address to connect to the iMac, make sure the box for "Add to my Computers" is checked, and it will add the IP address to the list so you don't have to put it in all the time.
Hope this helps,

How can I get my hp eprint email address from a remote location?
I am currently away from home and need to print something for my wife. I have tested out eprint before but never tried it from a remote location. I cannot recall the email address for my printer. Is there any way to retrieve this without being at the printer? I imagine that I had to sign in to the eprintcenter website to test this so alternatively, is there a way to retrieve the email address I used to set up my eprintcenter account? I am offered a way to retrieve the password but that doesn't help much if I cannot recall my eprintcenter account's email.
Thanks,
JeffHi Epoclaen,
I see that you are trying to locate your ePrint email address. The only way this can be done would be to log into your ePrint account so it would require you to remember your ePrint log on information. The email address that's used to create an account is usually your personal email address. I would try using your personal email address to log into the account. Let me know how it goes. -
Oracle Portal Development from different geographic locations
Hello,
Have anyone done the development with Oracle Portal from different geographic locations, our customer want to know is there a way we can develop Oracle portal application from different geographic locations and merge it one place.
One reason is because the portal is in the database. If you have two separate groups work to build a single portal, it reason that each team would have their own installation. When these two groups are done (or periodically), the development efforts must be merged into the final complete portal. Is this possible using Oracle Portal (merging portal installations)?
Second reason is that typically other systems owned by the customer are exposed or accessed by portlets. Access to these portlets would probably be required for development. If nothing else then for unit testing.
How do you typically see off-shoring done with Oracle Portal, if at all? Or am I incorrect in my thinkings. How does the Portal meta-data stores the portal configurations is it possible to merge different portal schema into one and make it the main portal environment.
Please let me know if anyone successfully done this. Your comments would be greatly appreciated.
Thanks,

Can you access an external HD plugged into the Airport Extreme from a remote location over the internet?
Also can the content on the exteral HD plugged into the airport be accessed by the TV to stream content?The first question answer is yes..
The question is asked continually.. please read the methods that Tesserax wrote up so well.
See remote access tip here.
AirPort
Also can the content on the exteral HD plugged into the airport be accessed by the TV to stream content?
Unlikely .. because your TV uses a system called DLNA.. and Apple do not support DLNA in any way shape or form.. because they are fully committed to iTunes.. Apple routers have no media extensions.. unlike most other decent brands now which mostly do support multimedia.
Having said that.. you can place your video files on the external hard disk.. and play them.. but you need a player.. a real player not an apple TV which is a streamer.. eg A WD Live TV can play video files.. because it is a media player.. unlike your TV or apple TV.
