Not able to communicate between the VLANS on SG300-10
Please take a look at my crude drawing of how I want my network to work:
SG300-10
__________________________________________

| Physical boxes |
| 192.168.20.x |
| W7 Workstations |
|_______________|
I put a static IP address on the server 2008R2 host and Internet router. I have configured my VLAN and I put each VLAN IP (as shown above), I put a 0.0.0.0 route to the Internet router, but also routes for each range of IP VLAN x.x.x.0 and I put the gateway on all host on VLAN 20 to be 192.168.20.1.
I'm unable to access the Internet, ping the router or access the webpage switch management of any host on VLAN 20 unless I manually set the IP address on the host VLAN 20 on the same IP range as the machine I'm trying to get. As such:
If I manually set the IP host address to 192.168.1.50, I can access the administration of the switch, but then not RDP in or ping any host on VLAN 20 or ping the router Internet on VLAN 10.
If I manually set the IP host address to 192.168.10.50, I can ping the router Internet but cannot RDP into or ping any device on VLAN 20, nor can I access the Switch Management page.
If I let DHCP assign the IP 192.168.20.5, I can RDP in and ping all devices VLAN 20, but I can't ping all devices on VLAN 10 or access the administration of the switch to VLAN 1.
I know I'm missing something simple, and I worked on it for about 30 hours now but can't seem to get this to work. Someone could possibly help? Thanks in advance.
Just to be sure, is the SG300 mode switching L3 / L2 switching?

4240, blocking some of the traffic between the VLANS local
I have an IPS 4240 in interface mode inline between our firewall switches and kernel in the periphery. This connection is a trunk with 2 port VLAN, lets call them A and b. everything works fine 100% between the VLANS (the firewall makes routing inter - vlan) except for SSH/telnet of VLAN A VLAN B, which is a big problem.
Everything works fine, including:
Web/443/TFTP from A to B
SSH/Telnet from B to a.
SSH/Telnet to nowhere A share around the world
SSH/Telnet from other networks to B
I removed the IPS of the equation, and everything is back to normal, so something must be up with the PPE.
This is a new deployment... so the sensor uses its default configuration. I don't see anything stuck. About the only thing that has been set up are the interfaces. I tried different values in the field VLAN by default in menu interface configuration does not, and I don't think it's related to the configuration of VLANS since https/web and everything works fine.
What I'm missing here? Any ideas?
Thanks AOT
There were a few [normalizer engine] signatures that will drop the traffic without alerting. I don't know if they still do, but check for active sigs that use the normalizer engine and is not an alert action.

Hello
I'm currently building the cluster by RAC 11 GR 2. I try to install Oracle Grid Infrastructure Oracle Linux 6.4 (x86_64bit) machine - node1.abc.com.
I'm at the stage of the "Cluster Node Information" where I have to provide me with the list of nodes to be managed by the Oracle grid Infrastructure. Currently I have added just me - node1.abc.com with the name of the virtual IP address - node1 - vip.abc.com. The two host name and virtual IP addresses are registered on the DNS server - it is also installed on node 1. Before adding the second node2.abc.com, I was testing SSH connection but it fails. I clicked the [SSH_Connectivity...] button and in the OS Username (grid) and his password. When I press the [Setup] button, it pops up message successful "Able to establish connectivity SSH without password between selected nodes." But when I click on the [Test] button or the [next] button, I get error - ' connectivity [INS-06006] SSH without password, do not put in place between the following nodes: [node 1].» What is the problem and what exactly to do to avoid this error?
Thank you
It was because I assigned a real static IP address for the second NIC eth1. With this affected YES wouldn't let you go to the next screen. So I had to remove NIC out of my laptop. But if eth1 is not resolved by the DNS name it also gives you errors. So I guess a correct functioning is I would sign up eth0 and eth1 to the DNS server but eth1 does not have real IP. Then I could go to the next screen.

Not able to connect to the server with modem 56 k
I try to connect my Tecra via modem 56 k Internet.
Also, I tried with another computer laptop with the same details and that worked.
But when I try it on my Tecra I get an error that is not able to connect to the server.So I think that it is a parameter that is not defined correctly for the modem.
(If you compare it to another laptop all parameters are the same as windows).Thanks in advance,
Theo
Hello Theo
Please remove the Dial-up connections all created and after that, remove the modem from Device Manager. Restart the device and initially ensure that the modem is properly configured (query modem Agic under Diagnostics). I put t know which Tecra you have, but many of them have preinstalled TOSHIBA PC Diagnostic Tool. With this tool, you can see all the equipment including modem.
After having it set up new Dial-up connection and check the functionality. Be sure to wait for the tone option is disabled.

I have a Dell Inspiron E1505 laptop and Dell AIO 924 printer if that helps! all cables are correctly connected, unplugged, replugged, shut down rebooted, uninstalled / printer driver, always even reinstalled!
uuggghhhhh!
flustered2,
You recently reinstall the operating system? If so, have you installed the drivers in the order?
How to download and install drivers in the correct orderFirst run delete print jobs to remove all print jobs stuck in the queue.
Unplug the printer.
Download and run the patch (cleaning printer utility) until it prompts you to restart your computer.
Restart your computer.
Now you can install the printer using the Dell Printer 924 disc.
Link to the patch/drivers(if needed) is to...
Dell 924 Photo-All - In - One Printer owners thread (W7)
Don't forget the programs anti-virus and firewall will block communications.
Also try this tweak...
Go into Device Manager (right click on my computer, left click Properties, material of the left click, left click Device Manager)
Go to the section USB controller, and then click the plus sign +.
Go to each USB hub root and right-click on it, on the left, click Properties, on the left, click power management. Uncheck the allow the computer to turn off this device to save power.
Restart your computer.

The error may occur if the wrong printer is set as default, the printer driver printer is missing, or if there are conflicts in Device Manager.
