NfSen Errors After Reboot

OreCollector · 11-20-2017, 11:34 AM

I am having difficulty with NfSen after a reboot. When browsing to the web page I receive several errors:

Quote:

Frontend - Backend version missmatch!

ERROR: nfsend connect() error: Connection refused!

ERROR: nfsend - connection failed!!

ERROR: Can not initialize globals!

I tried starting nfsen, but received an error.

Quote:

[root@nfsen bin]# ./nfsen start
-bash: ./nfsen: %%PERL%%: bad interpreter: No such file or directory

Any troubleshooting pointers, please?

What version? http://sourceforge.net/p/nfsen/bugs/43
Try web-searching the errors: https://sourceforge.net/p/nfsen/mail...sage/22868767/
Try -vx on the script (IF it is a script: use file command on it)
Try like: grep -r %%PERL%% .

Awaiting more info.

Thank you for the suggestions. I am running 1.3.6p1 and it looks like the path to Perl may be off.

[root@nfsen bin]#
[root@nfsen bin]#
[root@nfsen bin]# which perl
/bin/perl
[root@nfsen bin]#

I tried changing the path and managed to change the error message:
