Re: Tarsnap connection lost, not sure how to debug
Realised I did not answer your questions -- I am running this from a cloud server on DigitalOcean's network. A similar server on DO's network functions without issue. Networking-wise there are two adapters, eth0 and eth1, which connects to the internal network. This might've been added after tarsnap was set up... Perhaps that could be significant? # ls -l .tarsnap-cache total 0 -rw-r--r-- 1 root root 0 Feb 21 12:26 lockf # ls -ld .tarsnap-cache drwx-- 2 root root 4096 Feb 21 12:26 .tarsnap-cache On Fri, Apr 5, 2019 at 3:41 PM Julian Lam wrote: > Hi Graham/Colin -- I did see that page before and ran through the items. > No problems pinging or connecting via telnet, and a different server > configured the same way (at roughly the same time, give or take a couple > days) connects just fine.

Re: Tarsnap connection lost, not sure how to debug
Hi Graham/Colin -- I did see that page before and ran through the items. No problems pinging or connecting via telnet, and a different server configured the same way (at roughly the same time, give or take a couple days) connects just fine. Thought maybe ufw was getting in the way, so I punched a hole for requests to tarsnap's IP (no effect), and disabled it outright (also no effect). I'm seeing no obvious permission errors (I'm actually running as root), and I had also tried defining a new cache directory, which also didn't make any difference.

In addition to Graham's comments about debugging the network...

You only need to have a synchronized cache directory for creating new archives or deleting *individual* archives (since that's how tarsnap figures out which blocks are no longer needed -- not an issue if you ask to delete everything). -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid

Are you running this at home, or at an office or university? We have some info about network problems; please try the "debugging Tarsnap network problems" since that might help narrow down the problem. http://www.tarsnap.com/network.html > --print-stats outputs: > > tarsnap: Error reading cache directory from /root/.tarsnap-cache Are you running tarsnap as a normal user, or root? Can you do: ls -l /root/.tarsnap-cache ? - Graham
