I suggest switching to SFTP (SSH FTP), it seems that Adobe Muse supports it.

comment Adding a new domain to my VPS not working (CentOS/Apache)
Run dig +trace example.ro to see what's going on. Also if the question is about DNS, keep it short and don't mix it with HTTP (Apache) issues.

The Webmasters Stack Exchange is probably more appropriate for this kind of question.

comment create user on multiple ubuntu servers
You can store the passwd database on those servers. ArchLinux has some documentation about this. See also freeIPA which integrates multiple technologies in an easy to use package. If I'm not mistaking, there's also the option of using a Certificate Authority for the user SSH keys. Digital Ocean seems to have a tutorial about this.

comment Is there a “smart” file compression utility that can apply different algorithms to different files?
@Vilx-, yes, there are some old questions like that, but this doesn't mean it should still happen. In my opinion, general purpose questions belong to the Super User or Unix & Linux SE sites, where's a wider audience which includes regular users, not just system administrators. More people can benefit.

There is nothing server specific in your question.

Have you thought of using a directory service like NIS or LDAP?

comment My server got hacked
Try running chattr -ia /usr/bin/syslog before trying to delete it. Even if a process is still running under an user, you can still remove the account from passwd. Anyway, check out the canonical question "How do I deal with a compromised server?" and next time instead of compiling software from dubious sources, try using the official repositories (i.e. apt-get).

comment Can I send some text to the STDIN of an active process running in a screen session?
@ThorstenStaerk, I know, that's why I added that note. You're writing only to the device file corresponding to the terminal on which the gphoto2 runs (e.g. /dev/pts/19), the y character doesn't reach the application itself. It's the similar to what happens when you use the write(1) command. Anyway, either try my other answer or a graphical automation tool like xdotool.

comment Linux no space left on device issue
Not sure if this matters, but what filesystem are you using? For example XFS has some issues with full partitions, although your disk is not that full.

comment SED multiline recursive find and replace
I'm going to close this as a duplicate of the question dealing with compromised server because that's the right way to deal with this issue, but if you want to insist on using that workaround, you should check out the Super User and Unix & Linux Stack Exchanges.

As a side note tr '\0' '\n' < /proc/39259/environ should make the environment more readable.

@marp, make sure that the firewalld service is not running, but the iptables is.
