[SOLVED] nTop won't start anymore after migrating from i686 to x86_64

Like the title says it won't start anymore, well it does start bus the web-interface is inaccessible.

/var/lib/ntop/ belongs to root:root with permissions 755.

Also all plugins in /usr/lib/ntop/plugins/ are ELF 64-bit.

If you need more information just let me know.

As you say you have migrated, do you have any exisiting dot files in your home area relating to ntop? Does it work for other users?

Same error when trying to run as a other user. I also saw that there was a update on ntop today but the error remained. I didn't see any dot filer relating to ntop.

Re: [SOLVED] nTop won't start anymore after migrating from i686 to x86_64

I also saw that there was a update on ntop today

https://git.archlinux.org/svntogit/comm … kages/ntop

shows...
"2017-03-16    upgpkg: ntop 5.0.1-10"

which shows the update was over a month ago - what's the output of...

pacman -Q ntop

Also what does this show...

systemctl status ntop

Is there anything in your journal relating to ntop?

Just double checking you've also followed the wiki...

It may be that the 32-bit and 64-bit ntop databases are incompatible (I vaguely remember a similar issue when migrating architectures with vnstat).

Does removing all the the files in /var/lib/ntop/ and /var/lib/ntop/rrd/ help?

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan
Closing -- for deletion; Banning -- for muppetry. - jasonwryan

aur - dotfiles

Yes after removing all files in /var/lib/ntop/ and /var/lib/ntop/rdd nTop starts again, there goes 2 years of data :-(
