So I haven't dug into it, but I wanted to use "btrfs replace start ..." to swap a disk partition with an LVM block device, and got yelled at:

"Error: checking status of dm-0: No such file or directory"

I can work around this by ...

Cheers, my search-fu failed.

The notice is potentially confusing to folks who didn't know [1] or care that the Gentoo folks maintained more than one Github organization.

An answer to the following question would be useful:

Are URLs that start https://github.com/gentoo-mirror/ safe?

yes

Hi Progman3K,

You mentioned "you have a serial device." We can probably help more if you provide more details on what kind of "serial device", or the device on the remote end of this "serial device."

I don't have a lot of experience with HDLC on Linux, so while I believe you when you say your ...

I've seen this a bunch with software that doesn't know how to add a specific route back to the VPN gateway host itself.

If you're looking for a "why was the software written this way" that lets you fix it within the software, I'm not sure there's an answer to that.

With the xl2tpd setups I've ...

No solutions, just a specific problem description, to post here for posterity that hopefully saves some time for someone.

In a nutshell: I have a systemd [1] system, with an LV that has a partition I want to mount on boot. `udevadm info -e|fgrep ${vg_name}` doesn't show my LV though. Any systemctl ...

Inspecting smtp.mail.yahoo.fr:587/tcp indicates it's initiating in plaintext, not SSL. smtps:// is inappropriate; use smtp://

I leave it as an exercise to you to get Mutt to use STARTTLS properly in this scenario.

If you're not logging in via a DM, what's wrong with Keychain ? If I recall correctly there's a perfectly working .ebuild for this stable in the tree. Bonus is that it is designed to manage both ssh and GnuPG keychains and knows how to communicate to both ssh-agent and gpg ...

If you're still doing this, save yourself some trouble and use OpenVPN to bridge two segments together. By default it will emulate a 1500MTU-clean link by conducting fragmentation-and-reassembly on its own.

@inhibitor: Linux L3 forwarding is classless by default.


For example If I have next routing table

# ip route list
172.28.60.0/22 dev eth0 proto kernel scope link src 172.28.61.222
default via 172.28.60.1 dev eth0

If a packet comes in is destined for 172.28.64.100 then this packet is dropped ...

On the host, assign the ipv6 addresses to the bridge (br) not the members (veth eth1). ipv4 works because dhcpcd assigned an ipv4 addresss to the bridge.

We could use a look at your openvpn config to figure out what (if anything) you're doing to pin the local-side UDP socket to a specific port.

(By the way, https is typically a TCP protocol but your script opens it for udp/443, which might not be what you want.)

Actually at this point it's looking pretty nice to get a couple of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16833114037
and then find a small board to plug them into.

Just so happens that DD-WRT got a beta of the EA6500 firmware going a couple days ago, so I wasted a couple days ...

I'm not sure how the tun device is supposed to be created through rc. From rc.log:

* Bringing up interface br0
* Creating bridge br0 ...
set hello timer failed: Numerical result out of range


That bit looks bad. It looks a lot like rc was failing to set up your bridge device for this reason ...

Reading through /usr/share/doc/openrc-${VERSION}/net.example.bz2 may get you started; search for the sections that describe how to set up ethernet bridges and the comments should point you in the right direction.

Ok. My network controllers are:

What do you think ...

I need some help with OpenVPN. I'm in a hotel with Wi-Fi and almost everything except http ports locked. Luckily I have one server with ssh on 443 so I was able to socks-proxy for last 2 days. Nevertheless I decided to set up OpenVPN (also on 443) on another server to be covered for situations like ...

Though that was the goal I stated in my first post, my overall goal is to be able to communicate across the whole 172.16.1.0 subnet as below transparently such that Win1 and Win2 associate with the their wireless access point but do not know they are not physically on the same network.

Hi,

This config exhibits conceptual errors with regard to what ethernet bridges in Linux are and how they work. Try this:

config_eth0="null"

bridge_xenbr0="eth0"
config_xenbr0="dhcp
192.168.1.61/24"
routes_xenbr0="default via 192.168.1.1"
brctl_xenbr0="setfd 0
sethello 10
stp off"

dns_servers ...

Pretty sure that this is adequate, and would have pointed you in the right direction.

Incidentally, "0.0.0.0" might work but I'd probably go for config_$INTF="null" instead with openRC.

Check the source: src/garp.c

(disclaimer: just an idea; I haven't tried it since I'm not at home...)

It's possible br0 is being treated as an interface subject to ifplug, if you have ifplugd installed. Possibly try adding to /etc/conf.d/net?

You've provided very little information...

So start from the top: consider building a test system that has the right bits working. You might even do it on the machine itself with a recent LiveDVD if possible. If the test system has it working, figure out what's different between the test system and ...

aliased IP, which will be eth1 on one of the servers. This looks like it might all work, because it's all traveling over the same ethernet cable, no matter what the IP is. But it doesn't feel right. It feels like I might have packets from the LAN coming out on eth1, from my server's native IP ...

Does "ucarp" automagically do the ARP flood necessary for HA failover? The web documentation was a bit sparse on the details, and the online man page, while better, doesn't say, either.
Guessing that you're looking up www.ucarp.org's uCARP implementation... According to the README , yes, ucarp ...
