Is it possible in apache rever to have link translation?
We want to migrate our ISA 2006 webservices to Apache with reverse proxy but the link translation ISA uses isnt an option in mod_proxy it seems
We currently have an old RSA token - Radius environment we want to replace
Would this architecture be possible?
(this works, there are examples on the internet) Linux server Google Authentication Fee radius server
Now the new part: User list would get pulled from active directory, on the linux server the google authenticatior token would be (manually generated)
Or should we just create the users with the same name manually?
Our network supplier recommends replacing our 3 cisco catalyst 4500's because they are EOL and dont speak OSPF (which we really want)
Its not my area of expertise so I cant say for sure if we really need to replace these units but for my company the estimated costs of 250K euro is a huge problem.
Is there any way to cut down on costs (without moving from cisco devices), I heard the 4500´s can speak ospf but would need an upgrade of sorts?

The usual plugins are all about known stats of a system but we are seeing really odd results on some of our vmware instances with hdparm -t.
Anyone know of a test actually does a write/read on a disk or nfs mount in nagios?
is it possible to have nagios check for host down before a service failure is sent? if a host is down or rebooted we get a lot of service notifications but just need the 1 host down..
its a really annoying issue because we linked nagios to our ticket system
update:
Im not sure what happened, we have 2 nagios environments, I just inherited the environment from the other department and it was one of their major complains with it (was also new to me since my own environment has more checks and never had this issue)
After cleaning up the (hardly functioning) environment and implementing it in a helpdesk tool (otrs) I didnt see this behaviour so I suspect the messages were just in the minds of the coworkers (since nagios was mailing several times a minute!)
its now green after a few weeks hard work and the department is very happy with it...
sorry that I didnt close this issue before and thank you for your time!
another update: finally figured it out (I think). the nagios agent (opsview) crashed so it sends out the connection refused by host messages. I think that was bothering the IT department.
I have firefox running in xvfb (for nagios monitoring with selenium) but firefox crashes on me since today
in ps: /usr/lib/firefox-3.6.17/crashreporter /tmp/customProfileDira27173dd39e4467....
how can I see/fix the crashes?
I want to install some software (varnish) on a server and noticed that an older version 2.1.0 is in the current Ubuntu release 10.04 and the new version (2.1.3) is being build in the 10.10 ubuntu release.
is it safe to use the newer package? and if so, how can I do this?
ok, this is really pissing me off
I have one ubuntu 8.04 instance running on vmware (esx) which decided after a reboot to stop resolving dns requests, I also cant connect to it using ssh although I can ping the server and its really that server (when I shutdown the server the ping also stops)
stuff I tried: - reboot again :) - nslookup - serverip - setting networking to dhcp - offering some cute kittens to lucifer - removing the virtual nic and adding another (to get a different mac) - migrating the instance to another esx host - drinking 20 cups of espresso - stopped all services - running dnsmasq on another server and connecting to that dns - tcpdumping - disabling ip6
symptoms:
- cant resolve anything
- nslookup just says "no servers found..." although I can ping the servers
- traceroute to gateway doesnt work (even with traceroute -4 -n gatewayip)
- collegues laughing at me
any thoughts
solved it:
a collegue told me to upgrade/reinstall the vmware tools, I did and it solved my issue after rebooting
How can I use 3rd party tools like nagstamon nagios monitoring or the iphone tools with opsview? there is no cgi-bin anymore it seems (you get redirected to status/hostgroup)
We are having to make a design choice in our web environment. At this moment we are stuck at a discussion if we CAN put the varnish caching server into the vmware environment or on dedicated hardware.
My envisioned setup:
varnish/apache servers -> tomcat instances (in vmware) -> mysql cluster
(apache needs to be there because we want to be able to exclude varnish to troubleshoot caching issues)
this setup would serve 30+ tomcat CMS instances of which 3 would be large sites
our main issue would be if we have a large performance degradation if we put the caching server in VMWare
Does anyone here got any experience with caching servers in VMWare?
I'm running opsview (nagios) and 1 slave server doesn't execute some plugins correctly
Return code of 127 is out of bounds - plugin may be missing
when I execute the plugin manually it says
./check_icmp
bash: ./check_icmp: No such file or directory
on the master and other slaves it's working when executing the plugins
I have been googling and trying stuff for days now but can't get it working

I have a ftp user chrooted to a sub directory of another user which can read and write but the main user needs to be able to edit the files also
like this:
/user1/
/user1/user2/
how can I get this working in proftpd?
since its an www directory also it has to be secure also (no write for apache user)
We have nagios running but can't reach a different network directly. I would like to use Distributed Nagios eXecutor on a dmz server to execute checks in stead of building a new Nagios server and working with passive checks etc.
Does anybody know if this is possible to only do checks for some servers through a DNX server?
