RES: [load balancing] Alteon CPU for MRTG

Yanal,

Everything looks fine for me.  I´ll tell to do what I do to check for each
thing that I want to monitor:

I work with a very powerfull and easy MIB Browser:
http://www.mg-soft.com/download.html#MGMIBBPE

With this tool you compile a Alteon MIBs and GET a OID, graphics, etc....
In the trial version you can work with only 3 MIB at once, but I think it is
enough for you.

When I am shure that OID it´s ok, I configure the MRTG to do the graphics.

A thing that you have to verify is the WebOS version, because the Nortel eng
staff change some OIDs from a version to another. I sent to you the 9.x OID
version.

I´m sending to your email account a zip file with the MIBs, ok?

Claudio

[load balancing] Re: Foundry DSR / web server config question.

Well, I finally figured out the iplanet syntax -- was quite easy.  Just
add the following line for the 2nd ip to bind too in the obj.conf.

NameTrans fn="document-root" address="10.1.1.1" root="insert docroot here"

Where 10.1.1.1 would be the VIP for your loopback interface.  Then leave
the Address setting for the primary address in the magnus.conf and
everything works fine.

And well, what do you know, Tony's book specify's that you must set the
web server to bind on both those addesses.  I should refer to it more in
the future after all ;).

Re: [load balancing] Alteon 180e smtp load balaning

A copy of the config would be handy.

If you do in/slb/d what state are the real servers in.

[load balancing] Intel Adapter


Hi all the people !!

	I have some troubles in finding an Intel adapter to provide load
balancing to both my server2000 and clientsNT-2000. First, I would want to
know if I need the BIOS property "wake up on LAN" to implement load
balancing on clients and server machines. And second, I would want to know
which adapters could I use for this purpose.

Best regards,

Atentament,

I think you are not in quite the right place. This mailing list is focused
on external Layer 4-7 switching and load-balancing appliances, such as
these:

* Nortel Alteon:
    http://www.nortelnetworks.com/products/01/alteon/index.html
* Cisco CSS & LocalDirector:
    http://www.cisco.com/warp/public/44/jump/content_delivery.shtml
* Foundry ServerIron:
    http://www.foundrynet.com/products/webswitches/serveriron/index.html
* F5 BIG-IP:
    http://www.f5networks.com/f5products/bigip/index.html

What you're having trouble with, whilst still 'load-balancing' of a sort, is
to-do with what's commonly termed as 'network adaptor teaming' or 'NIC
teaming'.

If it's Intel cards you're using (or need), these URLs may help:

* Intel Desktop Network Adaptors:

RE: [load balancing] sync

I reran the config utility with the same results. Sync will only work from the stand by F5 to the active F5. force a failover try it again no go.

Any other suggestions

I would rerun config in its entirety.  That usually does it for me.

Why is it when I try to sync from the active F5 I get error 331828 check ssh ......

I can sync from the standby to the active with no problems. If I fail over the F5's I still can't sync from the active to the standby.

I reran the config_failover and the config_httpd commands. Still the same resultes.

Why?

RES: [load balancing] Alteon 180e smtp load balaning

Hi Jay,

I will talk about something that it happened with me:

1) Check if the route/default-gateway of your servers send the packets back
to your Alteon.  The health-check signal up it is not enough because in this
case the source ip is the Alteon interface and it isn't the client ip.

2) if you try "/i/slb/session/dump", you can see all the established
sessions( sip,sport dip,dport -> the server that was chosen by the metric ).
Try this: "/i/slb/session/find client-ip"

I am trying to get an alteon 180e (WebOS 8.0.30) to load balance 6 smtp
servers.  So far, I have had very limited success, and am not sure what I am
doing wrong.  The 6 SMTP servers are connected to port 3, with ip's
10.3.0.101-106 and the virtual server will be setup as 10.3.0.100 on port 7.
I created real server entries for each, a group for them, and a virtual
server, as outlined in the documentation. Then I enabled server processing
on
port 3 and client processing on port 7.  From port 7, I can ping 10.3.0.100,
but nothing connects.  tcpdump show arp requests going out, being met, and
the opening packets being sent, but no responce ever comes. Also, the 6 SMTP
servers never show a connection.  These are set up to use VLAN 3, and the
alteon has an ip of 10.3.0.254.  am I missing anything? Does anyone have any
hints?

Jay

I reduced the problem to 1 real server, to make testing alittle easier. Let 
me know if there is anything else you want.
