How to encrypt remote repo, with gcrypt or other?

Asked 2022-Apr-05 at 14:11

The goal is to store my code encrypted on a BitBucket remote repo. Something should deal with encrypting and decrypting so I landed on gcrypt or in full, git-remote-gcrypt.

I have a Bitbucket account with SSH keys configured.
This is what I've tried.

rsync

I copied these commands from the manual.

freetalk@bitbucket.org: I confirm this would never work, as an SSH URL to a Git remote repository hosting service would always use the 'git' user (and rely on the SSH key to authenticate and identify the actual user account).

spwhitton/git-remote-gcrypt commit 6233fde does mention:

Remove deprecated gcrypt::ssh:// (use rsync instead)

So a rsync URI seems more supported, as in commit 3b69f81

QUESTION

Intermittent connection failure to remote machine when remote (gdb) debugging with VS2019

Asked 2022-Mar-28 at 17:35

I'm compiling and debugging native C++ code on a Linux VM hosted (with Hyper-V) on the same machine on which I'm running Visual Studio 2019 (Enterprise Version 16.11.1). The remote connection only works most of the time. About 15%-20% of the time when I attempt to start the build or a debug session, it fails with:

"Could not connect to the remote system. Please verify your connection settings, and that your machine is on the network and reachable."

There is no reliable time period after which this happens (or doesn't). I can successfully remote-compile, then try to start debugging two (2) seconds later, and have it fail. Once it fails, I go to Tools > Options > Cross Platform > Connection Manager > [highlight already-selected connection] > Verify and I get a dialog box indicating "Connection verified.", indicating that it is in fact able to connect.

It can work fine many times in a row, and then suddenly fail. Once it fails, I have to close Visual Studio and re-open it to make it start working properly again. Through experimentation, I've found that I can also change the connection to a different remote host, and then back to the original again, to make it start working again, but that takes longer than just bouncing VS2019. It is becoming a real PITA to have to restart VS2019 every few minutes while developing.

Are others experiencing this intermittent failure, and/or have any ideas regarding what causes it or how it can be resolved (or even worked around faster than my current method)?

To view SSH logging in real-time logging on the remote machine, SSH to it and:

$ sudo journalctl -f -u ssh

(Optional: You can set the log level (e.g. to DEBUG, or INFO) in the SSH daemon configuration file.) On Debian, the SSH daemon configuration file is here:

/etc/ssh/sshd_config

You'll find that Visual Studio opens several SSH sessions to the remote machine, and closes most of them almost immediately after opening them. Each time you remote-compile or remote-debug, you'll see several sessions open and quickly close. There seems to be one or more, however, that persist. They eventually time out and are shut down by the remote SSH daemon, as evidenced by one or more logged message(s):

sshd[{*nix_process_id}]: Timeout, client not responding from user {user} {ip_address} port {random_port#} (where {*nix_process_id}, {user}, and {random_port#} are replaced by the obvious).

It is immediately after this/these session(s) time out that Visual Studio decides it can no longer connect, (even though it can). This seems like a Visual Studio bug, but I've found no info regarding it online.

My workaround is to set the following in the SSH daemon configuration file:

QUESTION

Prevent .libPaths() in R from resolving symlinks

Asked 2022-Mar-22 at 19:32

I have two almost identical systems. I install software in system1 (a remote testing environment) in /export/apps/ and then rsync the files to system2 in its /export/apps. For file system reasons, /export/ is really a symlink on each system. This usually works b/c for most many programs, any hard-baked paths contain the symlink and the file structure under the symlink is identical. So

system1 : /export/ -> /gpfs0/remote-test/export

system2 : /export/ -> /gpfs0/export

However, when I set .libPaths in R, R 'helpfully' resolves the symlinks. I have a strong suspicion that when I rsync this to system2, those resolved symlinks are going to break the installed software. E.g. (in R/4.0.0)

You need to escape the $ so that it will be sent literally to the remote machine. Otherwise, $(basename {}) is executed locally, and the output {} is substituted into the ssh argument.

rsync not working with variable containing a white space

ANSWER

Answered 2022-Mar-07 at 06:09

Add option -s with current rsync version.

From man rsync:

-s, --protect-args: This option sends all filenames and most options to the remote rsync without allowing the remote shell to interpret them. This means that spaces are not split in names, and any non-wildcard special characters are not translated (such as ~, $, ;, &, etc.). Wildcards are expanded on the remote host by rsync (instead of the shell doing it).

MySQL Replication: Question about a fallback-system

Asked 2022-Mar-01 at 08:18

I want to set up a complete server (apache, mysql 5.7) as a fallback of a productive server. The synchronization on file level using rsync and cronjob is already done.

The mysql-replication is currently the problem. More precisely: the choice of the right replica method.

Multi primary group replication seemed to be the most suitable method so far. In case of a longer production downtime, it is possible to switch to the fallback server quickly via DNS change. Write accesses to the database are possible immediately without adjustments.

So far so good: But, if the fallback-server fails, it is in unreachable status and the production-server switches to read only, since its group no longer has the quota. This is of course a no-go. I thought it might be possible using different replica variables: If the fallback-server is in unreachable state for a certain time (~5 minutes), the production-server should stop the group_replication and start a new group_replication. This has to happen automatically to keep the read-only time relatively low. When the fallback-server is back online, it should be manually added to the newly started group. But if I read the various forum posts and documentation correctly, it's not possible that way. And running a Group_Replication with only two nodes is the wrong decision anyway.

https://forums.mysql.com/read.php?177,657333,657343#msg-657343

Is the master - slave replication the only one that can be considered for such a fallback system? https://dev.mysql.com/doc/refman/5.7/en/replication-solutions-switch.html

Or does the Group_Replication offer possibilities after all, if you can react suitably to the quota problem? Possibilities that I have overlooked so far.

Many thanks and best regards

ANSWER

Short Answer: You must have [at least] 3 nodes.

Long Answer:

Split brain with only two nodes:

Write only to the surviving node, but only if you can conclude that it is the only surviving node, else...
The network died and both Primaries are accepting writes. This to them disagreeing with each other. You may have no clean way to repair the mess.
Go into readonly mode with surviving node. (The only safe and sane approach.)

The problem is that the automated system cannot tell the difference between a dead Primary and a dead network.

So... You must have 3 nodes to safely avoid "split-brain" and have a good chance of an automated failover. This also implies that no two nodes should be in the same tornado path, flood range, volcano path, earthquake fault, etc.

You picked Group Replication (InnoDB Cluster). That is an excellent offering from MySQL. Galera with MariaDB is an equally good offering -- there are a lot of differences in the details, but it boils down to needing 3, preferably dispersed, nodes.

DNS changes take some time, due to the TTL. A proxy server may help with this.

Galera can run in a "Primary + Replicas" mode, but it also allows you to run with all nodes being read-write. This leads to a slightly different set of steps necessary for a client to take to stop writing to one node and start writing to another. There are "Proxys" to help with such.

FailBack

Are you trying to always use a certain Primary except when it is down? Or can you accept letting any node be the 'current' Primary?

I think of "fallback" as simply a "failover" that goes back to the original Primary. That implies a second outage (possibly briefer). However, I understand geographic considerations. You may want your main Primary to be 'near' most of your customers.

If it already has it ignore it. I also need to exclude some directories within that search.

I know I can use the "stat" command in ansible to check for the files possibly in a loop "with_items" since it's going to be a bunch of directories maybe a wild card can be used?
