How to manage port 80 hosts via gateway - gateway vpn (rv220w)

I replace our aging rv082 routers with wireless rv220w routers. The gateway to gateway vpn works great, however I am no longer able to manage our print servers port 80 management page. I can ping any host with success, and I can manage hosts that have a port 10000 or 8000 web interface - but no port 80 ones... I had no issues when using the old rv082 routers...

How to manage port open/close on MacMini server

Dear all,
In order to secure my server, I discover than some port are open.
Is there a way to close all port and open only 445 and 548.
I would like to make sure that no body can access the server from outside of the society ecepted if the have VPN client configured.
The collaborator should be able to connect the server via afp, but form out side they need to use VPN.
Then I am looking for a way to manage port on macmini server
Many thank for your help
Cheers

Hi,
I finally heart that port can not be closed on the router because I am usinf 1:1NAT.
How can close all port on my Macmini and open only the port ssh. I will not use VPN.?
If I turn on the firewall with the option to close all protocole. Is there a command to open a selected port?
If there is only the port 22 (SSH) how can I mount a remote folder with afp or with somethin else? I also have on PC over the 7 iMac.
Many thank for your help
Cheers

How to manage the host root folder?

I'm using iWeb08, and I'm on system OSX 10.5.8.
Last week I flawlessly transferred my site from Apple to another host.
My question is, to make a few simple changes to it, {mostly text and links}, do I have to load up ALL the files again to the ftp host? I don't know how to manage the root folder yet and I don't want to clutter the folder or cause the site to malfunction.
Is there any useful posts on managing a hosting root folder??
Problems or thing I should know using iWeb08?
Thanks... Ghary.com

Once you get to know the file structure its possible to just upload the changed files by intelligent guesswork.
You can also look at the date on the local published files but this would be rather time consuming.
Most FTP apps have a synchronise feature to handle this for you but you need to set this up carefully and do a test run to make sure it doesn't wipe out essential files on the server.
If you do a lot of updates and you want to get your web pages downloading faster, an optimizer will do all the thinking for you. These screenshots are of one of Ton Brand's Optimizers - HTML Optimizer Plus
On the first pass all the files are optimized and uploaded...
After that, Smart Handling is turned on and only the changed files are processed...
The original folder is 10.1 MB and the Optimized one is 7.7 MB. That's without optimizing the PNG images. The finished site downloads fast. It needs to since its designed to work on mobile devices.

How to manage ports

Dear members,
My release is open Solaris b103
1- How to know the opening port in my system
2- How to open a specific port like port 53
3- How to closed the specific port like port 53

The question is a bit confused.
Ports are opened by applications. So if you are running an application that listens on that port, its open.
If you don't want the port open, don't run the application.
Port 53 is DNS. The easiest way to find this is "grep 53 /etc/services".
So if your running service dns/server then the port will be open..
To close it "svcadm disable dns/server"

Management port for management switch(2960x) / IP default-gateway for L2 management switch

1)
I am going to connect all mgmt ports of server to this access switch (L2; 2960x) like below. Then I have a management port in 2960x (FastEthernet / L3 port). As you can see below, even though one of Core switch is down, I am able to access through the other Core switch for mgmt SW. Do I need this FastEthernet port of 2960X?
Core Pri ------- Core Sec   (Core Pri 192.168.1.2 / Sec 192.168.1.3 / HSRP VIP 192.168.1.1)
            mgmt SW ----- (FastEthernet0) ------ Goes to where? I don't have RAS (Remote Access Server)
                  |
                  |
      servers' mgmt ports
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960/software/release/12-2_55_se/configuration/guide/scg_2960/swint.html#wp2220949
2) From server side, server put default gateway (192.168.0.1) so if destination is not known, it dumps all to default gateway. This is L3. I understand this. What about L2 default gateway from switch itself? The L2 access switch supports "ip default-gateway" command. I know that without this command still servers do not have any problems to connect to network. Then this command is for switch (2960x) itself? i.e I log into the switch and ping google.com then switch will try to resolve through DNS, but if DNS is not set up in the switch, it sends all traffic to "ip default-gateway"? Is it right?
3) If L2 (Access) switch has multiple data vlans and mgmt vlan (10.0.0.0/24 10.0.10.0/24 192.168.0.1). Then what will be the "ip default-gateway" for this switch?
Thanks for your time and knowledge.
======================== Reference from Cisco regarding ip default-gateway --------------------------------------
How to configure the ip default-gateway command on a Cisco 3550 series switch
VERSION 2
Resolution
To define a default gateway when IP routing is disabled, issue the ip default-gateway global configuration command. Then, enter the IP address of the next-hop router interface that is directly connected to the switch where a default gateway is being configured.
The default gateway receives IP packets with unresolved destination IP addresses from the switch. Once the default gateway is configured, the switch has connectivity to the remote networks with which a host needs to communicate.
Note: When the switch is configured to route with IP, it does not need to have a default gateway set.
For more information, refer to Assigning the Switch IP Address and Default Gateway.

How can I enable embedded pl/sql gateway to run on port 80

I have a new 11G install on OEL 4.0, database created. I would like to be
able to access the instance using the pl/sql gateway. Works fine with
port 8080, the default. How to I enable it to run on port 80?
I found this statement in the following docuementation:
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb22pro.htm#ADXDB2500
Using HTTP(S) on Nonstandard Ports
By default, HTTP listens on a nonstandard, unprotected port: 8080. To use HTTP(S) on
the standard port, such as 80, your DBA must chown the TNS listener to setuid ROOT
rather than setuid ORACLE, and configure the port number in the Oracle XML DB
configuration file /xdbconfig.xml.I have root priviledges on the box.
I've tried setting the listener file permissions:
chown root:dba /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
chmod 6775 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
Also put root in the dba group.
The permissions turn out like this:
-rwsr-sr-x 1 root dba 830854 Jun 17 21:04 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr
I stopped the listener, bounced the database, and started the listener again.
But it still shows the process being owned by oracle:
oracle 29682 1 0 21:08 ? 00:00:00 /u01/app/oracle/product/11.1.0/db_1/bin/tnslsnr LISTENER -inherit
Changing the port is easy:
Connected to:
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - Production

At this point, I can access the apex home page with the following url:
http://hostname:8080/apex/f?p=4550:10:1454849288245548
I can than change it to port 80:

dbms_xdb.setftpport('2100');
end;

When I try to access apex with the following url:
http://rmdcopslnx1.us.oracle.com/apex/f?p=4550:10:1454849288245548
I get the following:

This is the entry from the listener log:
<msg time='2008-07-03T15:40:09.741-06:00' org_id='oracle' comp_id='tnslsnr'
type='UNKNOWN' level='16' host_id='hostname'

So this looks like an permissions problem. But where? I posted
this on the apex forum here:

RD Gateway Manager - Unable to read RD Gateway Server Settings

I'm trying to install a Remote Desktop Gateway into my domain, but I am running into a serious road-block... when I load RD Gateway Manager to configure the service, there is nothing to configure because it won't load my server into the console. When I try
to connect to it manually, it returns the following error:
"Unable to read RD Gateway Server Settings"
There are no errors or warnings in Event Viewer. I can verify that C:\Windows\System32\tsgateway\rap.xml exists and is readable. I can verify that Network Policy does have a TS_CAP_01 policy and it is enabled. A valid certificate was applied during setup
(and I've also tried choosing ask me later).
I have already tried uninstalling and reinstalling the role service (including manually verifying that the policies are removed). I also have this working on another domain server, so I'm at a loss for what to look for... How can I resolve this so that I
can finish configuring the service?

Hello,
Thanks for your post.
From your description, I understand that you’re trying to install the RD Gateway role on a Windows Server 2008 R2-based domain computer. However, after the role
is install, the RD Gateway Manager cannot be loaded into the RD Gateway Manager. The error prompts “Unable to read RD Gateway Server Settings”.
Based on my experience, the issue may be caused by problematic installation or startup of the RD Gateway role. Before we troubleshoot the issue further, I recommend
you to enable the Audit level logging in the Event Viewer and double-check the related clues in the event viewer. To do that, please use the following steps:
1.
On the RD Gateway server open RD Gateway Manager. To open RD Gateway Manager, click
Start, point to Administrative Tools, point to
Remote Desktop Services, and then click RD Gateway Manager.
2.
In the console tree, right-click the node that represents your RD Gateway server, which is named for the computer on which the RD Gateway server is running, and then
click Properties.
3.
On the
Auditing tab, select or clear the appropriate check boxes to specify the events that you want to monitor for RD Gateway, and then click
OK.
When these events occur, you can monitor the corresponding events by using Windows Event Viewer. RD Gateway Manager server events are stored in Event Viewer under
Application and Services Logs\Microsoft\Windows\Terminal Services-Gateway\.
Let us know the result if possible. We’d like to help further based on your information replied. Thanks.

ICMP Host Unreachable from gateway localhost (127.0.0.1)

I had a functional zone. But we had an outage and for some reason one of my zones is unreachable. Looks like the problem is that the default route has changed. How can I add a default route to a zone?

You would see DUPLICATE or DUPLICATED in that field, and the flags would be different. Sorry, I don't have a duplicate IP situation going on right now, but my memory says it looked something like this:

New Install - ICMP Host Unreachable from gateway

Hi team,
I'm configuring a new solaris x86 box for the first time in a long time and I'm running into a problem that has me stumped.
I just installed Solaris 10 v7 on a P4 Dell box with an intel pro1000 adapter loaded.
Installed using ZFS and install went well. I set a static IP of 192.168.1.70 on a proper 192.168.1.x lan.
After install, everything seems to work fine but cannot ping a FQDN such as www.google.com, etc.
at first, I tried to join a local domain - maxximgroup.com and my computer name is set to sunzilla.
Here's my network config files;
sunzilla is set up with static IP = 192.168.1.70
# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 192.168.1.70 netmask ffffff00 broadcast 192.168.1.255
ether 0:1b:21:27:56:2c

inet6 fe80::21b:21ff:fe27:562c/10
ether 0:1b:21:27:56:2c
And /etc/hosts shows host name sunzilla associated w/ 192.168.1.70...
# cat /etc/hosts
# Internet host table
::1 localhost
127.0.0.1 localhost
192.168.1.70 sunzilla loghost
And my resolv.conf file shows my internal DNS routers as well as a 3rd I added (4.2.2.2) just in case...
# cat /etc/resolv.conf
domain maxximgroup.com
nameserver 192.168.1.20
nameserver 192.168.1.22
nameserver 4.2.2.2
search maxximgroup.com
I noticed the /etc/defaultrouter file was MISSING... so I created one pointing to my router...
# cat /etc/defaultrouter
192.168.1.1
And finally, I checked the /etc/nsswitch.conf file and it does indeed show hosts & ipnodes --> files & dns ...

Can anyone provide some guidance pls?

Thanks Robert. You were absolutely on the right track. It turns out that in my "rush" to get my new ZFS "toy" up and running, during the install, I gave Solaris a static address but told it to automatically find the gateway. Oops! When solaris 10 installed, it correctly decided that since it had a static IP, it should assign the gateway as itself! So, naturally, when I ran netstat -m, It showed my gateway as myself! 192.168.1.70 sunzilla.
I'm used to running Solaris on a Sparc platform and I'm a bit uncomfortable with reboots and I figured there would surely be a network restart command somewhere. After finding out that things have now changed in Solaris 10 quite a bit from Solaris 8, I just decided to init 6.
After the system came up, everything was happy : -)
So again, thanks to Robert for helping save the day!

Update/Insert mode couldn't apply to SQL Server source via Transparent Gateway.

Hi all,
OWB version is 9.0.2.56,database version is 9i Release 2.
When set load type to "Insert",mapping works fine from SQL Server to Oracle table,via Transparent Gateway 901.
But "Update/Insert" always runs error with "Fatal error or maximum number of errors exceeded".while I define both source and destination table to oracle tables in mapping,"Update/Insert" works file.
Any suggestion?

Hi Ignor,
Thanks for your reply!
The SQL Server version is SQL Server 2000.
I just want to ETL data from a SQL Server table via Transparent gateway into oracle table,the source table has a increment seq field,so I want to define mapping using update/insert loading method in OWB,according to this seq field,if there is the same seq in the target table,do update,if not,insert the row.I just find out that if I use a middle table in oracle to do truncate/insert mode from SQL Server source table,then do update/insert mode from the middle one to target table,it works.But can't do directly from source to target using update/insert mode.Does this means update/insert mode only apply to mapping from local table to local table?

How connect to oracle RAC via the RSG using port forwarding

Hi all,
I got a problem trying to connect to oracle RAC via the RSG using port forwarding .
on command line i sue to connect :
sqlplus 'username/password@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=firstRACnode)(PORT=1521))(ADDRESS=(PROTOCOL=tcp)(HOST=secondRACnode)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=MSDP)))'
but when using port forwarding i forward the port 1521 to a local port and make ssh to the DB node ( as normal with other nodes but not RAC) but it never work with me for this situation
can any one give me a help ifthere is any changes should be done on the server side , or if any one faced such a problem and found a solution
Thanks,
Prathap.

Step 1
Create a ssh tunnel from local machine to remote db server. Forward any local port (should not be a well known port or a port in the private/dynamic port range) to connect to the database server's listener port. If the ssh tunnel is into the db server itself, the connection (port forwarding) can be on localhost (as the Listener should be listening on it). Alternatively use a public IP of that db server.
Example (using OpenSSH on Ubuntu 9.4):
Local server port 1527 tunneled to port 1521 on database server 192.168.0.100 using o/s account johnd (we connect to port 1521 on db server via 127.0.0.1):
ssh -X -f -N -o ServerAliveInterval=3 -L 1527:127.0.0.1:1521 [email protected]
Step 2
Run sqlplus and connect to the local fowarded port on localhost, using the applicable connection settings (e.g SID/Service Name, etc).
sqlplus scott/tiger@"(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1527)) (CONNECT_DATA=(SID=orcl) (SERVER=dedicated)))"Note that the Listener must not hand our connection off - as the case would be when using RAC for example and connecting via a Service Name and not a SID. We need the Listener that accepts our connection to immediately hand us over to the database instance (via either a dedicated server or a shared server dispatcher process).

How to setup iPad Email to access school email hosted via google

Has anyone been able to set this up ?
I would like to setup my email account which is in the form of
[email protected]
Normally the email is accessed via the following portal which seems to be SSO for the google hosted service;
https://student.det.nsw.edu.au/
I tried several things including adding a google account, then exchange account, with no luck.
From speaking with one of the teachers at the school, it seems that students email is hosted via gmail.

Your post is a bit open ended....
First thing - You need to decide if you want to use virtual domains or not.
If
     [email protected]
     [email protected]
     [email protected]
all should be separate mailboxes, then you need virtual domains.
If those 3 addresses can all go to the same mailbox, then you don't.
If you don't need virtual domains, then don't use them... things are simpler without that feature.
If thats the case, in the domain name field in Mail service, enter your primary domain.
You'll then need to enter your other domains via command line.
First, check your mail domain setting with:
sudo serveradmin settings mail:postfix:mydomain
Here is how you enter more than one domain:
- Quit the Server app
- Issue this with your domains between the quotes
sudo serveradmin settings mail:postfix:mydomain = "domain1.com, domain2.com"
- Restart postfix to activate your change
sudo postfix reload
If you open the Server app, you will notice both domains are now listed.

How can I manage ports from terminal?

I'm trying to troubleshoot some issues i've been having using ssh with my two laptops. I'm getting a port 22 error and I would like to establish a customized setting that doesn't involve opening up these popular ports like 22. I'm trying to diagonse these problems every way I can but if I new how to manage this from the command line it would make things so easier. I would like to know how to open, close, view status, etc. of ports. Can anyone help?

There aren't any utilities to directly control ports because ports are a logical construct, they don't really exist. There are programming constructs to control ports, which are used inside programs to associate a server to a port and register that association with the OS.
For most programs, there are configuration files that can be edited to change various program parameters, including to what port the server listens.
SSH has configuration files for both the server and the client, at both the system and user profile levels.
You'd be better off giving more detail about what issues you are having. You might also (or additionally) try running your SSH commands with the -v, -vv, -vvv or -vvvv switches, which will cause increasing levels of verbosity to be printed to stdout...which can be very useful for troubleshooting.

Remote Assistance via RDS Gateway

Hi all,
any way to connect to a Remote Assistance session via RDS Gateway (re: way to embed / include and use an RDS Gateway)? My Googling / Binging has resulted in nothing.
Scenario - provide deskside support (Screen-sharing) to client(s) with already in-place and robust RDS RemoteApp farms. We're talking large-sized companies with a couple thousand PCs who are not going to turn 3389 on to the outside world, and leveraging
the already-in place security (RAP and CAP) and auditing / logging.
Seems like a fantastic idea to me. I'm hoping I'm not the first to think about it. :)

Remote Assistance should work in this situation, internally. Could you please provide a little more detail?
I know companies that use Remote Assistance through VPN to remote sites if thats what you're asking. Office Communicator also has a built in 'desktop sharing' feature. THen theres always VNC, or Dameware etc.
