kandi X-RAY | rsync Summary

rsync is a C library typically used in Backup Recovery, Incremental Backup applications. rsync has no bugs, it has a Strong Copyleft License and it has low support. However rsync has 4 vulnerabilities. You can download it from GitHub.

Rsync is a fast and extraordinarily versatile file copying tool for both remote and local files. Rsync uses a delta-transfer algorithm which provides a very fast method for bringing remote files into sync. It does this by sending just the differences in the files across the link, without requiring that both sets of files are present at one of the ends of the link beforehand. At first glance this may seem impossible because the calculation of diffs between two files normally requires local access to both files. A technical report describing the rsync algorithm is included with this package.

            pg_wal folder on standby node not removing files (postgresql-11)
            Asked 2021-Jun-14 at 15:00

            I have master-slave (primary-standby) streaming replication set up on 2 physical nodes. Although the replication is working correctly and walsender and walreceiver both work fine, the files in the pg_wal folder on the slave node are not getting removed. This is a problem I have been facing every time I try to bring the slave node back after a crash. Here are the details of the problem:

            postgresql.conf on master and slave/standby node

            ANSWER

            Answered 2021-Jun-14 at 15:00

            You didn't describe omitting pg_replslot during your rsync, as the docs recommend. If you didn't omit it, then now your replica has a replication slot which is a clone of the one on the master. But if nothing ever connects to that slot on the replica and advances the cutoff, then the WAL never gets released to recycling. To fix you just need to shutdown the replica, remove that directory, restart it, (and wait for the next restart point to finish).

            Do they need to go to wal_archive folder on the disk just like they go to wal_archive folder on the master node?

            No, that is optional not necessary. It is set by archive_mode = always if you want it to happen.

            How to Use Python to Iterate Through A Basic Website To Create List of URLs and then Print The Text of Each
            Asked 2021-May-31 at 07:59

            I would like to use Python to scrape all links on the Civil Procedure URL of the Montana Code Annotated, as well as all pages linked on that page, and eventually capture the substantive text at the last link. The problem is that the base URL links to Chapters that also have URLs to Parts. And the Parts URLs have links to the text I want. So this is a "three deep" URL structure with a URL naming convention that does not use a sequential ending, like 1,2,3,4,etc.

            I am new to Python, so I broke this down into steps.

            FIRST, I used this to extract the text from a single URL with substantive text (i.e., three levels deep):

            You are iterating through url_list twice.

            Assuming you want the text of each href written to a file, removing the duplicated for loop, saving the results into a list scraped data, then writing that list to a file in its own for loop works

            Answered 2021-May-27 at 21:42

            To give credit where it is due. The problem and solution were elegantly put forward by @IainShelvington in the comments above.

            Reason for problem: "Any files you write in a docker container will not be written to the host machine unless you mount a volume and write to that volume."

            Solution for problem: "Add a new volume to the global "volumes:" in your compose config. Mount that volume in the "django" service, all the celery services inherit from that service so it should be shared. Write and read the files from the location that you mounted (this should be completely different from the app mount, like "/celery-logs" or something)"

            To demonstrate what this solution would look like in my specific example, I added the following to my production.yml file:

            -i is option of ssh, not rsync. You are using -e. Good, but you have to pass to it all of ssh parameters in quotes. And second thing You have to tell rsync that You are piping something via stdin

            find /var/log/* -mtime +90 -print0 | rsync --remove-source-files -av -e 'ssh -i keypair.pem' --files-from=- --from0 /var/log/ ubuntu@ip:/

            Security question: Are NodeJS spawns logged anywhere?
            Asked 2021-May-25 at 02:46

            If you run a command in Terminal, say

            rsync -avuP [SourcPath] [DestPath]

            That command will get logged in, say .bash_history, .zsh_history, .bash_sessions, etc.

            So if you make use of something as notoriously insecure as sshpass

            say sshpass -P password -p MySecetPassword [Some command requiring std input], that too will be logged.

            But what happens when you do the equivalent when spawning a process using Node JS?

            ANSWER

            Answered 2021-May-25 at 02:46

            There isn't a node specific history file for execs unless you created one by logging the arguments. There can be lower level OS logging that captures this type of data, like an audit log.

            Passing a password on the command line is still considered the least secure way. Try -f to pass a file or -d for a file descriptor instead (or ssh keys should always be the first port of call)

            The man page explains...

            The -p option should be considered the least secure of all of sshpass's options. All system users can see the password in the command line with a simple "ps" command. Sshpass makes a minimal attempt to hide the password, but such attempts are doomed to create race conditions without actually solving the problem. Users of sshpass are encouraged to use one of the other password passing techniques, which are all more secure.

            In particular, people writing programs that are meant to communicate the password programatically are encouraged to use an anonymous pipe and pass the pipe's reading end to sshpass using the -d option.

            Vulnerabilities

            No vulnerabilities reported

            Install rsync

            Rsync normally uses ssh or rsh for communication with remote systems. It does not need to be setuid and requires no special privileges for installation. You must, however, have a working ssh or rsh system. Using ssh is recommended for its security features. Alternatively, rsync can run in `daemon' mode, listening on a socket. This is generally used for public file distribution, although authentication and access control are available. To install rsync, first run the "configure" script. This will create a Makefile and config.h appropriate for your system. Then type "make". Note that on some systems you will have to force configure not to use gcc because gcc may not support some features (such as 64 bit file offsets) that your system may support. Set the environment variable CC to the name of your native compiler before running configure in this case.
