Comment 3 Herman Viaene 2022-12-12 17:14:27 CET

MGA8-64 MATE on Acer Aspire 5253
No installation issues.
MCC mentions on netkit-telnet-server: "because telnetd is unsecure you have to manually activate it"
As in bug 26296, I chased around to find some way of getting this server running, but to no avail.
So as in that bug, the only thing I could do was provoking a time-out to my desktop which does not let it in, and in the laptop itself, open the firewall for the webserver, run the webserver and then
$ telnet mach7 80
Trying 192.168.2.7...
Connected to mach7.
Escape character is '^]'.


I go no further. OK for me as in the above bug.
