The documentation states that

ifquery --list

gives a list of all interfaces specified in /etc/network/interfaces (and includes). In fact in both Debian Jessie and Ubuntu 14.04 it lists all interfaces that have auto INTERFACENAME stanza and skips those without auto line.

Is there a way to list all interfaces that have iface NAME stanza using ifquery?

No, using ip link list doesn't do the trick because the interface specified in /etc/network/interfaces does not have to exist when ifquery is called.

I have 11 openwrt-based accesspoints in the building. Sometimes I need to add a virtual network with custom password. I don't like to iterate through accesspoints to change parameters. This is difficult and generate mistakes.

I would love to have a dedicated server (a virtual machine) that would keep and update all configuration. Is there a solution for that?

I know I can create a script that generates a configuration for each accesspoint and then scp it to all devices but before I do anything from scratch, I'll rather ask here. I don't plan to reinvent the wheel (unless the wheel is in fact no invented). I feel the simultaneous configuration is quite a common problem in a typical network with accesspoints.

Update: this is not only problem of passwords – this would be solved using Radius server but Radius cannot solve some other things like:

1. creating new essids
2. assigning essids to vlans
3. enabling/disabling essid broadcasting
4. etc., etc., etc.

I need to set EPC mode on Seagate Constellation disks connected to LSI 9690SA-4l controller. This is because the controller is not compatible with the disks unless the EPC mode is set – according to page http://mycusthelp.info/LSI/_cs/AnswerDetail.aspx?inc=8187

The thing is we can't google any way to set the disk mode using Linux. Is there any Linux tool to set such a mode?
