Multiple domains to single IP
I am pointing multiple domains to a single IP on the F5. Say I have domaina.com domainb.com domainc.com and they are all pointing to 10.1.1.1 in DNS. I have an irule that will take [HTTP::host] and then decide if it is going to a virtual directory on IIS. 10.1.1.1/domaina 10.1.1.1/domainb 10.1.1.1/domainc 10.1.1.1 is the F5 server which load balances off to two IIS servers with hypothetical IPs of 10.1.2.1 and 10.1.3.1. The IIS servers are defined as nodes in the pool serving a VS for this multiple domain configuration. when HTTP_REQUEST { if { [domain [HTTP::host] 2] equals "domaina.com" } { HTTP::redirect http://[HTTP::host]domainA[HTTP:uri] HTTP::redirect http://10.1.1.1/domainA } elseif { [domain [HTTP::host] 2] equals "domainb.com" } { HTTP::redirect http://10.1.1.1/domainB } elseif {[domain [HTTP::host] 2] equals "domainc.com" } { HTTP::redirect http://10.1.1.1/domainC } } This gets everything to where I want it to go (so far, I'm new at this and I haven't tested anything except a single page yet, and there is probably a better way to do this), but, the address bar comes up with http://10.1.1.1/domainc. Since they are public-facing websites, it would be nice to maintain the http://domaina.com/domaina or ideally just http://domaina.com. When trying the commented out piece, that just results in a loop because it continues to redirect itself. Perhaps there is better logic to run the condition against, or maybe I have the wrong approach. Any ideas? It would be great to sort that out, as then you could have conceivably infinite domains running different sites from a single IP. One problem I am facing short term is that I am running out of IP addresses. It also crossed my mind to instead make virtual servers for each domain that spoke on the same IP address to the IIS servers, but different ports. Any input you might have would be most appreciated!
Run commands remotely on a BIG-IP load balancer????
Is there a way I could run commands remotely on a BIG-IP Load Balancer. I would want to run some Adminstration and Maintanence commands remotely on the BIG-IP load balancer. I would like to run the commands sitting on my Linux (or Windows) box, maybe through a shell script and get the information. Get the configuration and statistical data on the remote machine. If possible I would like to get this done without SNMP.
Mapping SNMP interface index to interface name
My iControl application is given the SNMP interface index which is a numeric value identifying a specific BIG-IP port/interface. iControl, of course, identifies interfaces by a string ("1.1", "2.1"..etc). So, I need to map this numeric value to the string. How do I do it?? I don't see any api in v4.5 of iControl to retreive the numeric index value of an interface. Are there any plans for introducing such an api in v4.6?? Thanks, Karthic.
node select expr based on server_addr
I'm going to map a server IP address (server_addr) for a wildcard virtual server to a pool member using the following node select expression: select node("192.168.0." + getfield("${server_addr}", '.', 4) + ":${server_port}") Does this syntax make any sense? Will it work? Is there more efficient way to choose a pool member IP address based on the server_addr variable? Thank you, Dmitriy
Find F5 machines in my network
Dose anybody knows how can I automatically search for F5 machines in my network from a Java program?. I tried to scan a F5 machine using nmap but it does not send any respond. I suppose F5 block or ignore that kind of traffic to improve the security. Can someone give me some idea?. I have thought to try to connect to the iControl portal using https for each ip, but I think ther must be a better method. Thanks: Miguel Fernandez
Hw do I save configurations on a bigip?
I can see the stuff in ConfigSync. But how does that relate to: bigpipe base save and bigpipe save It would appear that ITCMSystem.ConfigSync.save_configuration with the right flag will save either, but on the command line version the filename is different. Can I ommit the filename to use the default? If I don't specify a fully qualified path, will it go in /config?Irule to log client source IP
I am trying to log the source IP address of every request that hits a VIP on a 4.2 BigIP to a file, /var/log/ldap_clients.log on the Bigip. Right now there is no irule on the VIP, it is just using a pool. rule log_client_address { if ( client_addr != 0.0.0.0 ) { use pool corp_ldap_3895 log (dont know how from here) } else { use pool corp_ldap_3895 } } Any help with syntax and logic is greatly appreciated.
