.. what is? fellow centosians. how to you mount your loopback targets? I'm trying lvm backstore, I was hoping I would do it with uuid, but it's exposed more than once and how would kernel decide which device to use I don't know. thanks

nobody does use iscsi loopback over an lvm?

I'm not sure what 'iscsi loopback' even means. iSCSI is used to mount a virtual block device hosted on another system (initiator mode) or to share a virtual block device (target mode), while loopback is used to mount a local file as a device, such as an .iso image of an optical disc. can you

dear list. this question is rather related to samba, although not exclusively. I consider it related enough to ask here, please apologise if you don't. we are in the process of setting up a samba domain at my company. a goal is to replace our current nt4 servers. another goal is to provide an easy way to access the documents on the lan (and peoples home directories) from 'outside'

I raised the questions below a couple of months ago by sending it to the developers mailing list, but I don't know if it got through since no one replied to it. Looking at the [R] distribution, the UseMethod() is used in the following way: alias <- function(object, ...) UseMethod("alias") or barplot <- function(height, ...) UseMethod("barplot") What I

Hello all, In your view, what is the most reliable and safe way to increase an LV housing the root filesystem of a Centos 6 VM. I am thinking either growing the virtual HD virtual device, or creating a new device and adding it as a PV to the VM, or perhaps migrating the whole FS to a new virtual disk. Any input on how best to proceed would be appreciated. Cheers, Boris.

Yes and no. Some of the attack vectors mentioned are not reasonable and it really depends on the client. Thunderbird, for example, used to have settings for plain text, TLS and "TLS if available", but the latter setting has not been available for some time which forces...

...ary packages as possible (best way to find them?) - install dovecot (not included in centos, IIRC) and other extra packages you do need - run yum update - enable long passwords - set up only ssh2 on a non standard port - set up Single Packet Authorization? - set up itables (what would the safest iptables script to do all and only the services listed above? - what else? Feel free to rearrange, cut, add, give links, whatever: personally, I'm interested in securing the whole box, meaning how to glue things together in the safest possible way, without forgetting anything, while things...
