sftp error

Wizzzard — Mon, 12 Aug 2024 16:55:21 -0000

The jssh library from jcraft is probably too old. There is a fork of that library that works with the new defaults for SSH servers. The program should be repackaged with this forged version, IMHO. The fork is here: https://github.com/mwiede/jsch

Trouble transferring files via FTP to vsftpd running on AWS EC2 instance

Christoph — Tue, 28 Jan 2020 07:33:15 -0000

Hi Kevin,
have you tried uploading files with FileZilla or just tried to connect? From the log it looks like FullSync is able to connect but fails to upload a file because the server denies that.

BUT: FTP is a horrible protocol. If at all possible use SFTP (filetransfer over SSH - not to be confused with FTPS which is just horrible FTP with TLS).

I assume that you can SSH into your EC2 instance already, so using SFTP would remove an additional service that you need to expose to the internet.

BR,
Christoph

Trouble transferring files via FTP to vsftpd running on AWS EC2 instance

Kevin Price-Ward — Mon, 27 Jan 2020 15:46:55 -0000

Hi,

I'm having real trouble getting fullsync working with vsftpd on a small Amazon EC2 instance. I'm able to connect to it fine with FileZilla and other FTP clients, but fullsync is proving problematic.

I'm doing a publish/update from a local directory on my Mac to a FTP server which I've set up on AWS EC2 with vsFTPd.

I'm trying to do this over old style, non-TLS FTP connection, I have enabled the correct ports on EC2 and I think I have my vsftpd conf file configured correctly.

I have managed to connect, I think, but no files are being transferred to my FTP server, here is the log file from fullsync:

To me it looks like a permission error? But the FTP user I am connecting with has full write access so I'm not sure.

Also here is my vsftpd.conf file in case there's an issue with the way I have it configured:

You may activate the "-R" option to the builtin ls. This is disabled by

default to avoid remote users being able to cause excessive I/O on large

sites. However, some broken FTP clients such as "ncftp" and "mirror" assume

the presence of the "-R" option, so there is a strong case for enabling it.

ls_recurse_enable=YES

When "listen" directive is enabled, vsftpd runs in standalone mode and

listens on IPv4 sockets. This directive cannot be used in conjunction

with the listen_ipv6 directive.

listen=NO

This directive enables listening on IPv6 sockets. By default, listening

on the IPv6 "any" address (::) will accept connections from both IPv6

and IPv4 clients. It is not necessary to listen on both IPv4 and IPv6

sockets. If you want that (perhaps because you want to listen on specific

addresses) then you must run two copies of vsftpd with two configuration

files.

Make sure, that one of the listen options is commented !!

listen_ipv6=YES

pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES

pasv_enable=NO
pasv_min_port=1024
pasv_max_port=1048

allow_writeable_chroot=YES

rsa_cert_file=/etc/ssl/private/vsftpd.pem
rsa_private_key_file=/etc/ssl/private/vsftpd.pem

force_local_logins_ssl=YES

Can anyone provide any insight here?
Thanks in advance
Kevin

Replacing JAVA with OpenJDK

Christoph — Fri, 13 Dec 2019 19:51:32 -0000

Hello Jan,
The version of FullSync installed by the windows installer is 32bit only. The Java VM you use is 64 bit, thus FullSync doesn't start.
Also I'm not sure if the released FullSync version will run with Java 11.

Also I suggest using the semi official OpenJDK builds from https://adoptopenjdk.net/releases.html istead of Zulu. On that page select OpenJDK 8, HotSpot for Windows x86.

If you prefer to use a 64bit Java VM you can get FullSync with 64bit support by using the "FullSync without Installer" variant for Windows from https://fullsync.sourceforge.io/download.php

I don't have a windows install at hand to test this out right now, but I guess you don't need my help for that anyway :)

If you run into any problems with that OpenJDK build please let me know!

Also as a side note: Future FullSync for Windows installers will likely switch to 64bit and bundle an appropriate OpenJDK verison from AdoptOpenJDK :)

Br,
Christoph

Replacing JAVA with OpenJDK

Intro Dev — Thu, 12 Dec 2019 16:29:34 -0000

Same problem here with Zulu VM 11 -> https://www.azul.com/downloads/zulu-community/?&architecture=x86-64-bit&package=jdk

Does not work - why??

When i try to start launcher.jar, i get that message:

java -jar launcher.jar launching FullSync... OS=win32-win32; ARCH=x86_64; INSTALLLOCATION=file:/C:/Program%20Files%20(x86)/FullSync/FullSync/

...and nothing happens anymore, the console will continue waiting for that next command.

No Window that opens, nothing...

Thx for feedback.

With best regards, Jan

Hi,
drop the attached jar file into the /home/eric/Bureau/FullSync-0.10.4/lib/ folder and you should be good to go!

This i slikely caused by an incompatibility of FullSync with more recent Linux Distribution releases...

I'll see if I can update that this weekend and let you know.
