I have a set of linux boxes, running RHEL 5. All have the same set of packages installed, and the same hardware/BIOS/DRAC versions.I have ~3k ACPI interrupts a second on one CPU, on some, but not all machines. This indicates I can find what's causing the ACPI interrupts (or at least the interrupt types) by poking around /sys/firmware/acpi/interrupts/, but I don't seem to have a /sys/firmware/acpi/interrupts/. Any idea how else I could find the cause of the interrupts?
I'm using a proxy: action in mod_security2. I'd like to preserve the full URL of the original request, however, and it seems to be rewriting that to the url in my proxy: action.
So a request to http://domain.example.com/foo
hits my the below statement
SecAction proxy:http://internal_error.example.com/
This seems to be getting proxied to http://internal_error.example.com/, which I'd like it to be proxied to http://internal_error.example.com/foo
Is this possible?
I have a Cisco 3750 stack. When I try and ping a device connected to one of the interfaces, the output packets counters on the interface do not increase. The input packets counter on the interface is increasing however (irrespective of whether I'm pinging the device). None of the error counters are increasing, and I am getting both an ARP entry and a mac-address-table entry. The IP I'm pinging from is in the right VLAN and subnet to ping the device. Any ideas what I can do to troubleshoot this error?
Is it possible to change the time mails are kept in quarantine on an ironmail?
I have R65 installed on Solaris 9, on Sun4u. It's currently running into an issue where during long connections (I think. It doesn't appear to do this to all connections, and I can't work out what the difference between those affected and those not is) it stops allowing traffic after a certain period of time. No traffic is logged as being dropped. When I use fw monitor -p All, I can see the traffic reaching stage five outbound (fw VM outbound) and getting no further. The start of the connection sets up properly however, and I can see the connection logged as passed in Smart Tracker. fw ctl debug doesn't seem to point me to anything useful, nor does fw debug fwd. Is there anything obvious I'm missing that could be causing this?
On an OS/2 box, what do the flags UGDP mean in the output of netstat -r. Google seems to point to them meaning Up, Gateway (i.e. an indirect root), and Dynamic (learned from a redirect), but that leaves me mystified as to the meaning of P. The only suggestion I've had is permanent but that doesn't make any sense with dynamic. Any ideas?
We currently run a bunch of physical machines. For backups, we've been using dirvish, which is essentially a wrapper around rsync, and doing them incrementally. We're currently pushing a new machine into production, which is going to run a whole bunch of VMs. Ideally, I'd like to back up the virtual machine images, rather than doing file level backups from the VMs themselves. Is there a way to do this incrementally, given that each image will be one giant file, which will require a new backup anytime anything changes? How do other people do VM backups here, just treat them as physical machines?
If it matters, we're using Xen to actually do the virtualisation.
Thanks
When I view the logs created for my checkpoint fw1, does it log connections on receiving the syn, or does it wait till the three way handshake completes? If it logs after the syn, is there anyway of telling where the three way handshake has not completed?
I need to add several static routes to a solaris 10 box. On Solaris 9, I've always made these persist across reboots by adding an init script to reapply the route. With solaris 10, adding a service to an SMF seems somewhat overkill. What is best practise on how to add a route that persists across reboot?
Is there a way to copy a firewall policy from a managed device to the managing machine, using the dashboard? I realise that you can view the policy on any of the managed devices, but there doesn't seem to be a way of saving it once viewed.
Where does an ubuntu machine get the default domain to append to users when sending mail? Ours is currently sending as [email protected], while /etc/mailname has mail.example.com set. Should this not be sending as [email protected]? I'm using exim4, and I've dpkg-reconfigure'd it so that the system mail name, and the visible domain name are both set to mail.example.com.
--edited to include mailserver--
I need to find the compile options for exim, as packaged by fedora 11. More generally, is there an easy way to find what options a particular rpm was compiled with?
