Digging into the problem, I fixed it running this command: setsebool -P httpd_can_network_connect on The issue was generated by SELinux: the Read more…
Today I’ve discovered Plop Linux, a LiveCD distribution with sshd server enabled at boot. Usually Linux LiveCD don’t have the sshd service on autostart for security reasons.

You have to use the root account and the password of your linux server, you have made no typo errors, but no way to go ahead.
Usually, if you have this problem, you cannot use also the VMware console from a remote IP (eg. you cannot login to your server from your workstation, even from the same LAN).
Recently I have found this problem in many Linux distributions and I have figured out how to fix this serious problem…
I was a great fan of Kmail email program, but recently I have to use Mozilla Thunderbird (manly because now I’m cross platform AND cross OS: Kmail is only for the Linux/KDE flavor). Thunderbird is powered by a great spam (junk) mail filter: you can enable it from the account’s Read more…
Per diverse ragioni, mi trovo “costretto” ad usare i servizi online di poste.it, alle volte… Beh, usare e’, nel caso specifico, una parola grossa 🙂 Oggi, per l’ennesima volta, il sito non risponde.
