Access NLB cluster from outside
I crated nlb cluster using 3 servers, one is used to create cluster and other 2 for hosts. I assigned 192.168.1.2 for cluster ip. Every server has two nic and one of nic connected to public ip. My worry is how can I access cluster from out side? As mentioned
in
this question I asked my server provider enable NAT and this is their reply. "We dont offer any NAT solutions but you can easy set up one of your servers to perform this."
can anyone tell me how can I do this?

Hi chapneox,
Could you clarify your question, I am not quite understand your description “can I access cluster from out side”. You can use the “Internet” IP address as your NLB virtual
IP address. But if your cluster after NAT or firewall you must map the NLB port from the NAT or firewall device.

is it possible to access my TimeCapsule from outside my local network via internet? If so what is the best app that can help me?
iCloud can do it..
http://www.apple.com/au/support/icloud/back-to-my-mac/
You need Lion and latest firmware on the TC..
Were you hoping to use the ipad/iphone?? That maybe possible but I am not sure how.
You cannot use windows without opening SMB to some strange port and this is going to mess with security.. you also need a static ip address from your ISP.. most private net users do not have this.
You can do it via vpn.. you will need to buy a vpn router and bridge the TC to it.
Just google remote access time capsule.. there are a zillion posts about it. -
Trying to access my 851w from outside my lan, but can access inside fine
Hi,
I purchased a 851w to use as my home router and to learn more about the cisco IOS. I have been spending some time studying for CCENT/CCNA and so far I have enjoyed learning as I go. However, I am having problems accessing this router from a remote location via ssh. I can access it just fine from my lan, but not outside it from another location. Currently, I am not using this router for internet access or anything else other than learning about the IOS, and it is connected to a basic dlink wireless router dir-615. I have port forwarding setup on the dlink that any traffic coming in on port 22 is directed to the 851w at 192.168.0.150. I also have the 851w connected with a crossover cable to a switch that is connected to the dlink router.
Like I said, I can connect just fine from my lan, but can't connect from outside. I have tried a few different things but nothing works. I also use Teraterm to connect, but have tried Putty too. I also use ddns to access it, but I have also tried the wan ip address of the dlink with no luck.
Could someone please take a look at my very basic running config and explain what I might need to do different?
Thanks in advance.
SeanHi and thanks a bunch for your quick response.
No, I can't ping anything other than my main router which I have setup as the gateway so why is that? For example,
ip default-gateway 192.168.0.1
Wouldn't it automatically send anything it doesn't know about to the 192.168.0.0/24 router?
I have one of the switch ports, Fast Ethernet 0, connected to another switch connected to the dlink router. I have tried different ports but it didn't change anything. I don't have anything connected to the wan port of the 851w. I was trying to simulate remote access of a switch on an internal network. My next step would be to make the 851w my default router and then try to access it from the outside, but I wanted to succeed this way first.

Windows server anywhere access not working from outside the lan
ok so heres what i have done so far i installed windows server 2012 essential on a computer followed the wizard to add a couple of users and gave them anywhere access followed the wizard and ran the anywhere access to completion setup the ports 80 and 443
on router manually to forward to my router ip 10.0.1.20
my server is still on dynamic ip
then i go to a windows 7 ultimate computer whent to the connect url downloaded the connect tool ran to completion and restarted the computer so far everything working inside my lan i can connect to the server see shared files and open the dash management
now i go outside connect to a wired or wireless network of a friend and try to connect to http://xxxxxxx.remotewebaccess.com
but am unsuccessfull then i check on my network adapter page and see that there is a new adapter that is called as my remotewebaccess.com so i click on it and try to connect but still fails........
please help what am i doing wrong?
i checked everywhere and cant find a solution.
Thank youIt is probably better to assign a static IP to your server, but OTH it may not change. But you really hate to go off on vacation and have the ip change and everything break.
Now you said you forwarded ports 80 and 443 to your router, I bet you meant your server?
Do www.whatismyip.com and from outside ping xxxx.remotewebaccess.com and make sure they are true same ip
From a PC or the server on your network go to grc.com and do shields up and make sure it reports 80 and 443 as open

How to make the application access the fonts from outside library?
actually the fonts located in the library are considered from the system/library/fonts path. is it possible to make it accessible from outside that path through programatically for indesign applications? if yes means, how to do it?
thanks
subhai think am not mentioned the question clear.
the fonts menu inside InDesign lists the fonts from
for mac: System/Library/Fonts
Adobe InDesign CS2/fonts
for windows: C:\WINDOWS\Fonts
C:\Program Files\Adobe\Adobe InDesign CS2\Fonts
is it possible to list the font from someother folder rather than this folders.

How to access OBI Dashboards from outside Network.
Hi Gurus
I want to access MY Dashboards Reports from any where on internet. My BI server is available on LAN so how i ;ll make it available to access it from any place.
Any Reference DOC, Blog or guide.
Regards

I've just re-read your original question - If you want the BI Server accessible on the internet you need it visibile outside of your firewall - Your network people should be able to set up any routing you need to achieve this.
Chances are if you have a VM running on an internal server, you wont have this access by default - there are various security hoops to jump through to get this working. -
How can I easily access my photos from outside iPhoto?
My wife recently got a Mac for the first time and imported all of her photos into iPhoto. Today she was trying to upload some photos to a community website. The website had a Browse button that opened a Finder window. We were quite surprised to find that there was no easy way to access her photos. It seems like they are all in one big 100GB database file. We can "open" that file and in a Master subarea we can find the photos arranged by the date of import.
Is there a way to easily access photos, and find the ones we want? On Windows here photos were just kept in the file system with Albums correspondiong to directories and both Picasa and Windows Live Photo Gallery worked fine with this approach, and it was trivial to find a photo from the explorer.Is there a way to easily access photos, and find the ones we want?
Absolutely
Under the media heading in the lower left of the browse window click on Photos ==> iPhoto and you events/albums/etc from iPhoto will be there - not sure how much easier it could be

Accessing a collection from outside of Apex without causing a HTTP redirect
First, some background:
I am running Apex version 2.2.1.00.04 on Oracle9i Enterprise Edition Release 9.2.0.7. IE 6 and Flash 9
My Apex page contains two third-party Flash controls. Each Flash control uses a passed in URL to get the data that it will display. The data that I need to pass to the Flash controls is stored in an Apex collection created in my page.
Using the technique outlined in the following posts,
Re: Accessing Collection through a DBMS.job
Re: Accessing application item value from database
I have created a stored procedure that will attach to my Apex session and query the collection. See procedure get_data below.
The URL that the Flash controls are passed is like this:
http://myhost/pls/mydad/get_data?p_user=MYUSER&p_session_id=535622580488397200&p_app_id=2332
The call to WWV_FLOW_CUSTOM_AUTH_STD.POST_LOGIN causes a HTTP redirect to the Apex at page p_app_id:1. The Flash control that initiated the request never sees the data stream that the get_data procedure is sending via HTTP.P. Instead, it sees the HTML produced by the Apex page at p_app_id:1.
Now, my question:
Is it possible to call the WWV_FLOW_CUSTOM_AUTH_STD.POST_LOGIN command in away that does not cause a HTTP redirect? If not, then is there another series of commands that will attach to an Apex session but not cause a HTTP redirect?
Thanks,
Ken
CREATE OR REPLACE procedure get_data(p_user IN VARCHAR2,
p_session_id IN VARCHAR2,
p_app_id IN VARCHAR2) as
BEGIN
APEX_CUSTOM_AUTH.DEFINE_USER_SESSION(p_user,
p_session_id );
APEX_APPLICATION.G_FLOW_ID:= p_app_id;
WWV_FLOW_CUSTOM_AUTH_STD.POST_LOGIN(p_user ,
NULL ,
p_session_id ,
p_app_id||':'||'1' );
FOR c_collection_rec IN (SELECT c001
FROM APEX_COLLECTIONS
WHERE collection_name='MY_COLLECTION')
LOOP
HTP.P(c_collection_rec.c001);
END LOOP;
END;Ken - No way to prevent the redirect attempt, that's what the procedure is built to do. To use it otherwise is aberrant. I think you could use an on-demand process (FOO) callable from the URL that would spit the data back out. You do this by defining an application process (on-demand firing point) and callling it from the URL ( f?p=APP:0:SESSSION:APPLICATION_PROCESS=FOO). If the cookie is passed in the request (meaning you've authenticated) and authentication check passes again in your process request, the process will produce the result stream.

Accessing the SMTP from outside network through ASA 5510
hello good people,
I have an issue with my mail server(SME Server) which is behind a Cisco ASA 5500(firewall) problem is that if one leaves my network they can receive but can not send email via my SMTP also internal people can only send if they use the IP address of the server rather than the domain (mail.xxxx.com) any pointers will be appreciated.
here is my layout
ISP - ASA 5510 - LAN (includes mailserver)
Kind regardsHello George,
If you have public DNS , in order to access the servers hosted inside using their fqdn, then you need to have dns doctoring. but unfortunately, you are using port address translation ( not a one to one nat) which doesnt work well with dns doctoring..
I assume you can solve this issue with alias command as follows
alias (inside) 199.199.199.99 255.255.255.255
Also, for the other issue can you try to configure an SMTP inspection as follows
policy-map type inspect esmtp esmtp_map
parameters
allow-tls
policy-map global_policy
class inspection_default
inspect esmtp
Hope this helps

Access Action Listener from outside
Hi,
I have been working on a clone of the classic Minesweeper game to get better acquainted with Java and programming in general.
If you were to open up Minesweeper, you might come to understand my difficulty better. Notice how, if you press on any of the buttons (or anywhere on the pane), the smily face reacts with a surprised look.
I have my clone set up with a JPanel component which contains a grid (for the buttons) of JButtons. I can't figure out how to get my MouseListener within my JPanel to notice when a button is clicked. Any ideas on how to get this interaction to work?
Thanks!Read the tutorial: [How to Use Buttons, Check Boxes, and Radio Buttons|http://java.sun.com/docs/books/tutorial/uiswing/components/button.html].
You should add an ActionListener to each of the buttons and not a MouseListener to the JPanel. -

I am not able to access my sap from outside of network.

Any idea. Thnaks in advance
Regards.Hi,
Hope you have private external IP than dynamic which changes every now and then you can this:
P <Public ip> * 3299 or P <Public ip> SID_IP 3299
Also look for your the logs for saprouter and your router logs if this not works.

How to access Oracle Enterpise Manager from outside my VM
Hi,
I've Oracle VM VirtualBox version 4.1.2 installed on the host Windows XP and pre-built Database App Development VM (Updated Nov. 2011) worked on it.
Everything is OK, I have NAT network and can run Enterprise manager inside my VM on URL https://127.0.0.1:1158/em
Pleas, describe shortly:
1.How I can access enterpise manager from outside VM ?
2.What I have to write (HOST, PORT etc) in my tnsnames.ora file on the host system for the VM Oracle server to connect it from the host system ?
Sincerely,
Alex
Edited by: AlexR on Dec 31, 2011 5:24 PMHi Alex,
the host and port depends on your network setup of your VM.
Do an ifconfig -a and see what IP adress your guest has.
With this IP address you should be able to access EM from outside your VM (but on the VM host, not from outside the network) with the same port.
Regards

http 0.0.0.0 0.0.0.0 outsideHello Mohd,
Here are the facts:
I honestly think you need to change that route statement as it basically says if you want to contact the NARAYASERVER send the packet via the INSIDE interface to the IP address 172.27.17.100
route inside NarayaServer 255.255.255.255 172.27.17.100
interface Ethernet0/1
nameif inside
security-level 100
ip address 172.27.17.100 255.255.0.0
So basically send the packet to yourself (Does not make any sense.. Try to read it so you can understand what I mean.
The NAT 0 is breaking the translation.
access-list inside_nat0_outbound extended permit ip host NarayaServer any
nat (inside) 0 access-list inside_nat0_outbound
Do the following :
access-list inside_nat0_outbound permit ip host NarayaServer OTHER_site_VPN_subnet
no access-list inside_nat0_outbound extended permit ip host NarayaServer any
Then u should be able to connect,
Let me know if you will follow my instructions, otherwise I think I am not helping here
Note: As you already mark the question as answered you could provide kudos (stars) on my next answers

Accessing a server via the Server app from outside a router firewall
So I'm trying to access my server using the Server app on a MacBook Pro outside my server network. I can access it just fine when my client is inside the server network, but I cannot connect when outside the server network.
I've done the following troubleshooting:
- I've turned off the server Firewall option available in the server's Server Admin tool
- I've set up port forwarding on my router
- I've opened up port 311 on the router
- I've placed the server outside the router DMZ zone and the Server app connects just fine
- I've checked the box "Allow remote administration using Server" in the server's Server app Settings tab
- With the router configured correctly, the Server app cannot access the server
There's something in the router that is blocking access by the Server app. Apple Enterprise support says they are sure there is no other port to open up. Is there something else I should be doing to access the server from outside the router using a client Server app?
TIA
ps - this worked fine when I just had the server hanging directly off a cable modem.I and I suspect a lot of other admins would argue you should not be making your server accessible via Server.app remotely due to security concerns. Saying that, I and again I suspect a lot of other admins also want/need to be able to remotely administer servers. There is a better way however to achieve this.
You should be running a VPN server, perhaps using your same Mac server. You should leave the firewall blocking access directly for Server.app but if your remote Mac first connects via the VPN it will then be connected securely to your internal network and then be able to use Server.app
