iLO 2 Responds to Ping yet cannot connect via http/s

iLO 2 Responds to Ping yet cannot connect via http/s

All -

I have two DL380 G6 servers with an iLO2 interface with updated firmware and drivers. Both iLO interfaces respond to a ping yet I cannot connect to either of them via port 80 or 443. We have a number of other iLO interfaces on thes same subnet which I can connect to, demonstrating it isn't a network problem. I have also tried resetting both.

The OS is Windows 2003 R2 SP2 (x32 and x64).

Suggestions?

Are you sure other devices on the network aren't using the same IP addresses as the iLO's? Unplug the iLO's ports from the network and see if you can still ping the IP addresses

I did that already, they do not respond when unplugged.

Try and configure a DNS entry pointing to the ILO interfaces and use a FQDN as connection medium

Try to use the HPONCFG utility while logged on the server itself to change iLO settings; the default ports of 80 and 443 may have been changed.

Try to use RDP to remote into the server and then use SMH to check/verify the iLO port security settings and interface status?

Re: iLO 2 Responds to Ping yet cannot connect via http/s

Hi all -

HPONCFG.EXE shows port 80 and 443 configured as expected. When logged onto the server via RDP, the Management Processor status is Enabled, NIC Condition OK, and it is in a green state.

I haven't connected a laptop directly to the iLO port. Do I need a crossover cable?

yes a crossover cable is recommended

Hi Megan,

Can you explain exactly what happens when you try to connect to the iLOs ?

If you're using Internet Explorer, what error does it display ?

Cheers,

Rob

Re: iLO 2 Responds to Ping yet cannot connect via http/s

IE displays different errors depending on if I am using the IP vs. the hostname. If using Firefox, the error is "The server at x.x.x.x is taking too long to respond".

Re: iLO 2 Responds to Ping yet cannot connect via http/s

is this witha direct connection and what version of explorer

Re: iLO 2 Responds to Ping yet cannot connect via http/s

No, I haven't tried the Direct Connect yet. I am using Firefox 3.0.16. It make take me a couple of days to get back to you regarding the direct connect.

Re: iLO 2 Responds to Ping yet cannot connect via http/s

To rule out any browser or proxy errors, have you tried telnetting directly to the port 80 or 443 on the iLO and see if it connects...

Re: iLO 2 Responds to Ping yet cannot connect via http/s

As Rob Leadbeater wrote if telnet connection to 80 and 443 ports not successful, I think it rules defined on network switch, proxy, etc. Try to direct connect to iLO, maybe temporarly from other server.

So Megan whats the status..

Re: iLO 2 Responds to Ping yet cannot connect via http/s

I apologize for the delay. Here are the details:

* I am able to ping the iLO interfaces
* I am unable to connect to iLo via any web browser
* I am unable to telnet to port 80 or 443
* I connected directly to the iLO port via a cross over cable and could successfully connect to iLO via web browser.

I am now engaging my network team. I hadn't engaged them previously because I am able to connect to other iLO interfaces on the same subnet and we normally do not block based on specific IPs.

Re: iLO 2 Responds to Ping yet cannot connect via http/s

It turns out the iLO network we use for iLO interfaces uses a non-standard subnet mask and gateway. I have reconfigured it and it now works. What threw me is the fact I was getting a ping reply. Oh well.

Can I just assign all of you points for being so helpful?

Re: iLO 2 Responds to Ping yet cannot connect via http/s

Hi Megan,

I should have thought of that... Having the wrong subnet mask can cause all sorts of strange things to happen.

> Can I just assign all of you points for being so helpful?

Of course you can... You can (and should) assign points to all replies.

Hello Megan,

I have the same issue and looking ahead to reset gateway and subnet. can you tell me how could you reset them since we could not open the ILO through web browser.

Thanks in Advance,
Rahul
