DigitalOcean droplet server does not work

[scusi]

Summary

smp-server binary from the release page with BuildID cd99e16fec87f49fbfc352350b688e9f90f36e56 DOES work.
smp-server binary from the DigitalOcean droplet with BuildID 9dcbeeef5875acc615c486a4c55be8b125592628 DOES NOT work.

What i did

I used the simplex digital Ocean droplet and run it.
Then i downloaded the simplex-chat (client application) and tried to connect it to my new server (running on digital ocean).
unfortunately this did not work. I got the following error message:

me@mybox:~$ simplex-chat -s smp://tXC4IMc1KUOAEYfXwX+S9ACu2EEitBlSxqCObdKDBEU=@simplex.scusi.io
option -s: @: Failed reading: satisfyWith

How i found out

When i tried the same thing with one of the offical server, it works.

I downloaded the server binary from the release page and started it locally on my computer.
I connected to my local instance, did work, as seen below.

me@mybox:~/$ simplex-chat -s smp://h9ZEZW7uiweKkT6DtExxo5JI9mgyGjc1vSp8wBHaGaE=@127.0.0.1
SimpleX Chat v1.0.0
db: /home/me/.simplex/simplex_v1_chat.db, /home/me/.simplex/simplex_v1_agent.db
type "/help" or "/h" for usage info
[...]

Next thing i did was to check if the local server binary is the same as the one in the digital ocean droplet.
Turns out it is not.

root@simplex:~# file /opt/simplex/bin/smp-server
/opt/simplex/bin/smp-server: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=9dcbeeef5875acc615c486a4c55be8b125592628, stripped

The local server binary (downloaded from the release page) is different from the above.

me@mybox:~/Downloads$ file smp-server-ubuntu-20_04-x86-64 
smp-server-ubuntu-20_04-x86-64: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=cd99e16fec87f49fbfc352350b688e9f90f36e56, stripped

After finding out that the binaries from the release page and the droplet are different i just uploaded the release binary into my droplet and overwrote /opt/simplex/bin/smp-server.

After replacing the smp-server binary from the droplet with the one from the release page it also works for me with my digital ocean droplet. I think the digital ocean droplet needs some love and a binary to be updated.

P.S. Thank you for that software project, i like it.

I think the digital ocean droplet needs some love and a binary to be updated.

Absolutely - we are currently updating droplet to be v1 - the previous version that is currently deployed to DO is not compatible with v1 client, sorry. We should have it up within less than a week (accounting for DO approval).

We probably should update readme for now - we will do it!

Thank you for that software project, i like it.

Thank you so much!

Have the same Problem.

I followed the Instruction into the Readme file:
https://github.com/simplex-chat/simplexmq#deploy-smp-server-on-digitalocean

connection seems to works fine, /cs lists my contact:

$ simplex-chat -s smp://fingerprint@ipaddress
SimpleX Chat v1.3.1
db: /Users/XXXXX/.simplex/simplex_v1_chat.db, /Users/XXXXX/.simplex/simplex_v1_agent.db
type "/help" or "/h" for usage info
Current user: XXXXX
1 contacts connected (use /cs for the list)
> /cs
USER (USERNAME)

Got error when try to do following commands:

> /address
smp agent error: BROKER {brokerErr = TIMEOUT}
exception: HandshakeFailed (Error_Packet_Parsing "Failed reading: invalid header type: 0\nFrom:\theader\n\n")
...
> /connect
smp agent error: BROKER {brokerErr = NETWORK}
exception: HandshakeFailed (Error_Packet_Parsing "Failed reading: invalid header type: 0\nFrom:\theader\n\n")

Current, by Droplet installed, Version:

>/version
SimpleX Chat v1.3.1
To update run: curl -o- https://raw.githubusercontent.com/simplex-chat/simplex-chat/master/install.sh | bash

I realize the sha1 hash is identical as in the initialising thread from scusi: #292 (comment)

$ file /opt/simplex/bin/smp-server
/opt/simplex/bin/smp-server: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=9dcbeeef5875acc615c486a4c55be8b125592628, stripped

So how can i upgrade the DigitalOcean droplet to the newer version?

P.S. Nice Project

Is is indeed not updated unfortunately, need to chase their support again... There is a not on their page, but probably not that noriceable... Sorry

Please use Linode for now - the stackscript is up to date

Hello epoberezkin,

thanks for the Information.

I find a simple Solution, maybe they are helpful for others:

1. Delete my Droplet of simplex
2. Build my own Digital Ocean Image by the Instructions from here:
   https://github.com/simplex-chat/simplexmq/tree/master/scripts/smp-server-digitalocean-droplet
3. After the Image was created, i was able to create a droplet from the Image in the Digital Ocean Site
   (you should find one under the "Image" Section, after planer has build it successful).

Have no problems in this version.
