Hi, I read about the invitation protocol that will be introduced in 1.1pre8. Is there any mechanism of UDP hole punching to establish a VPN behind NAT?

Ah! I'm noticing that configuring static ports on the NAT in front of a tinc node with a public IP seems to make a difference to the number of other tinc nodes that can then establish d...

I have a number of datasets that are multipunch column-binary format. Does anyone have any advice on how to read this into R? Thanks. David

Wasn't there a TV series in the 1960s about a US soldier who got made up to general thanks to the accidental over punching of paper tape?

This is the second version to support efficient zero for block devices on older kernels (e.g. RHEL 7.5), and file systems that do not support yet FALLOC_FS_ZERO_RANGE (e.g. NFS 4.2). Changes since v1: - Split to smaller patches - Skip linux only includes on other systems - Skip code using BLKZEROOUT if the macro is not defined - Try BLKZEROOUT only if the offset and count are aligned to device

The only requirement is that you have *some* nodes on your graph that are not subject to NATs. In your case that would be your linux boxes. If you add your laptop and Windows machine to that graph by establishing tinc connections between them and...

Even if the hole punching is executed, the modification time of the file is not updated. So, current time is set to inode.

Because of space limitations and because of the location of the punch-down blocks, my * server is located on the shelf in a coat closet. Sadly, there is not enough space (or ventilation) for the monitor and keyboard. This will all change when we move to new quarters, but... Does anyone have experience running Linux/Asterisk without a monitor? What, if any, are...

...N work line etc. I'm aware that I can forward VM to email or use a web interface but that is not always practical. Other than doing an IVR type arrangement or a phone number dedicated to VM access is there a way to do this? On my old POTS line I used to be able to call my line and simply punch "*" during unavailable message playback to go to the equivalent of voicemailmain(). Is there a way to do this in *? Thanks!

We're currently support two paths from VFS to preallocate unwritten extents(from FS_IOC_RESVSP, or fallocate()), likewise, behavior of punching-hole should be treated as the same, this patch tries to teach file_ioctl() to handle FS_IOC_UNRESVSP, underlying filesystem like ocfs2 is wise enough to do the rest of work;-) Signed-off-by: Tristan Ye <tristan.ye at oracle.com> --- fs/ioctl.c | 10 +++++++--- include/linux...

Any tips or guidance on improving the probability of being able to connect to a Tinc daemon. I am currently on a guest wifi at a hospital for my in-laws family. Wanting to pass time and be semi productive, I tried to VPN back to my private networks but it appears the default port Tinc users is blocked. Here is what I know about their firewall:

Hi Guus, Unfortunately, I often notice that even with the advanced UDP hole punching mechanisms that tinc uses, I still come across cases on my network where two nodes behind NATs cannot talk to each other because one of the nodes is behind a "strict" NAT that won't use consistent source ports for UDP packets that are sent to different destination addresses.

...es on the adit and I get green lights on both the T1 card and the T1 interface on the adit (so they seem to be happy at that link level). I configured the T1 interface in the asterisk box to do 'fxsls' signaling on all 24 channels. Couple questions: 1. Should I be getting dial tone on my punch down block yet? I can tell the handset it getting power when I touch it to the correct places on the punch down block, but no dial tone. Does asterisk need to be aware of these channels before dial tone will be heard? 2. Did I configure the digium card correctly? Does it need to be setup as fxo...
