Nop, wouldn't do the job, because `cp --attributes-only` requires a target file system, however I need something which records those attributes in a file that I can use afterwards to restore them (or compare them with further versions, etc.).

Thus I was wondering if someone knows a tool that fits this description. I must say I've tried to do my homework, and below are a few tools that come close, but not quite... (A) `rdup` is probably the closest to what I'm searching. However there are a few issues: * it's output format is not very parsable, especially in cases like symlinks, and a few other special cases; * it doesn't escape the file names --- and from some reason I have files containing escape sequences in them... * it records only SHA-1; * it doesn't handle ACL's or extended attributes; (B) `mtree` from FreeBSD. I found two ports of it for Linux, however my main concern is how parsable is the output... (C) `md5deep` (or `sha*deep`), which only records the checksum not other meta-data. Thus, are there any other alternatives? (Just to be clear, I don't need a backup solution, just something to record file-system meta-data. Maybe a meta-backup solution... :) ) Ciprian. Have a look at 'tripwire'. It's primarily an intrusion detection tool, but it does the job by recording file meta-data and checksums, then checking to see if they have changed. I can't remember if it handles ACL's, as it's been a few years since I used it. -- Reverend Paul Colquhoun, ULC. http://andor.dropbear.id.au/ Asking for technical help in newsgroups?

Re: [gentoo-user] VPN connection from gentoo to OSX server?

So far I can't make a good vpn connection from this linux machine or my android tablet. I can log in using a vnc client and poke around in the server settings, so I know that the server is configured to use L2PT/PPP and not just PPP. I'm pretty sure that's where I'm going wrong. I have every L2TP option set in my kernel as well as all the tunnel and ppp/pppoe options I can find (knowing very little about the subject), but I can't tell if my attempted connections are really using the L2TP protocol or not. Syslog says nothing about L2TP, so I'm guessing there's something configured wrong on my end. I'm using networkmanager-pptp for the vpn connection, and the networkmanager config applet mentions nothing about L2TP. Has anyone else done this successfully? Thanks for any clues. I haven't used L2TP to comment on specifics, but have you emerged and set up xl2tp which I understand will set up the L2TP tunnel? L2TP will be encapsulated within IPSec, which you should set up using racoon, strongswan, etc. -- Regards, Mick signature.asc Description: This is a digitally signed message part.
Re: [gentoo-user] monitoring system resource usage
Agreed! Although getting apache, mysql, and nginx plugins fully working is proving to be a little trickier. To get those going it's necessary to edit /etc/munin/plugin-conf.d/munin-node as well as some apache and nginx config. Still working on getting it all 100%. - Grant If you have a fairly basic setup, post what you are using to help others later on. At least it could give someone a config to go by. I promise I will do this once I feel good about my config. - Grant

Hey all Is anyone aware of a way to shut google-talkplugin up? It is really uselessly noisy during Hangouts.

Sometimes when I am setting up something, I google for the config file to see if I can find something to go by at least. I did that the other day with my xorg.conf file. I found out that when I logout and leave, my monitor never goes to standby. I found a config file that someone posted that had the info I needed. It was MUCH faster than trying to read man pages and find it. I thought about setting up a site or something and putting different config files there and allowing others to post theirs. Thing is, I'm sort of low income and I don't know how much that would end up costing me. I'd do it for free so I'd pay for whatever it was. I think a central place for this sort of thing would be great. Anyway, it may help the next person if you post what works for you and maybe how you are using it. At least give someone a start. If they google, they will find it. Dale :-) -- I am only responsible for what I said ... Not for what you understood or how you interpreted my words!

It's a bottomless empty pit, so no physically real copy would be made. I would be curious to find out how one can use `/dev/null` as a replacement for an **entire** file-system (i.e. not just a replacement for a stream sink)? And how would the `cp` command be used to obtain such an outcome?
