Description

Hello Patrick,

I try to connect to JASMIN through eduroam as but I get this message:
'ssh_exchange_identification: read: Connection reset by peer
ssh_exchange_identification: Connection closed by remote host'

I looked up the problem on JASMIN website here:
https://help.jasmin.ac.uk/article/190-check-network-details
where, under the heading 'Check IP address resolves to network domain (all users)', it says to check this:
https://accounts.jasmin.ac.uk/services/reverse_dns_check/

which I did and got this response:
External IP address: 134.225.30.179
Reverse DNS lookup failed

Would you know what the problem can be and how to solve it?

All the best,

Azin

Hi Azin:
I have had similar problems in the past, when I was on eduroam WIFI on the University of Reading campus.

The solution was to contact (IT) (email = it at reading.ac.uk), telling them about the problem, and maybe they would put that IP address on a reverse-DNS list of some sort.

Are you actually on eduroam WIFI? Or are you actually on the VPN provided by the University of Reading?

I haven't had these problems when I was on the VPN, as far as I remember.
Have you tried to use the VPN while you're on eduroam WIFI?
Then, your computer will be considered to be part of the University of Reading network, and you shouldn't have reverse DNS problems.

Are you on eduroam WIFI hosted by some other institution besides the University of Reading?
If the eduroam WIFI is hosted by someone else besides the University of Reading, then you should probably contact the tech support for the other institution, to fix this.

Hello Patrick,

I needed a university connection to connect to JASMIN. I could not use the university VPN because my laptop is too old for the new version of VPN. However, I got connected to JASMIN by using the university act-ssh and the help of IT services. Here is the link:

All the best,
