pilse secure 8.2R4 on Fedora 23 x86_64 JSON problem

[mikele6427]

Hi all,
I'm trying to use PCS to connect my university vpn. My linux box is Fedora 23 x86_64 with kernel 4.7.10-100. I installed all required i386 and i686 packages but still can't connect correctly.
Autentication process seems to go well but I can't get status informations and no bytes are sent/received. Launching UI from command line and after disabling firewall and selinux, I can get some useful information:

there is some error related to the proxy (but it's not used) and about Json-parser, that is correctly installed on my box.
Pulse secure for windows on the same hardware and same credentials is working correctly, so we can exclude server-side issues.
Any help will be appreciated

Is Host Checker being used?
I think you may have found something new, unfortunately, as the error appears to indicate that there is no username provided

[zanyterp]

Do you know if the server version is also 8.2R4?
I would recommend opening a case with support for further investigation

I don't know Host checker, sorry I'm noob. I ran ConfigurePulse.sh and it is ok. I think the missing username depends on the impossibility to parse data in the login form. Am I wrong?

I downloaded the 8.2R4 version from the university wiki page, so I think they should support that version. I asked support but they are not giving so much help until now.

After reading this post: https://forums.pulsesecure.net/topic/pulse-connect-secure/1001811-pulsesvc-on-64bit-fedora24-v82-5-120 I checked my log and I have the same error related to resolv.conf.
I successfully connected to university vpn by using lubuntu 16.10 and I noticed that the content of /etc/ resolv.conf is actually different before and during the vpn session.

This error seems to be the key issue
sysdeps.error rename /etc/jnpr-nc-resolv.conf => /etc/resolv.conf failed wirh error 2 (sysdeps.cpp:978)
jnpr-nc-resolv.conf does not exists in Fedora and there is no dns available for vpn connection. It should be relatively simple to fix the error.
Is there any Pulse secure staff member reading this forum?
