* σε Linux η διαδικασία ειναι αντίστοιχη, το αρχείο βρίσκεται εδώ: /etc/hosts Συνολικά ανα λειτουργικό το παρακάτω άρθρο παρουσιάζει την όλη διαδικασία αναλυτικά: https://support.rackspace.com/how-to/modify-your-hosts-file/

Καλησπέρα σας, για να δείτε κάποιο website προτού καν ολοκληρωθεί το DNS propagation μπορείτε να τροποιήσετε το τοπικό host file στον υπολογιστή σας. Σε Windows η διαδικασία περιγράφεται ως εξής: το αρχείο βρίσκεται στο %WINDIR%\system32\drivers\etc\hosts πχ το αρχείο είναι σχεδόν πάντα το: C:\Windows\System32\drivers\etc\hosts ( μπορείτε και με Windows Key + R για RUN και να γράψετε απλά drivers, σας πάει στο: C:\Windows\System32\drivers, ένα βήμα πιο πίσω ) να προσθέσετε εγγραφές με την νέα IP και το hostname του τύπου: IP {domain.com} IP {www.domain.com} πχ 51.255.201.167 designhost.gr 51.255.201.167 www.designhost.gr άμεσα και χωρίς κάτι άλλο θα πρεπει να δείτε το website στην δηλωμένη IP ενδέχεται να απαιτείται από Command Prompt : IPCONFIG /FLUSHDNS Για να επαναφέρετε το σύστημά σας απλά διαγράφετε τις γραμμές αυτές από το τέλος του hosts file και ξανά IPCONFIG /FLUSHDNS

σε τέτοιες περιπτώσεις το εργαλείο CXS (ConfigServer eXploit Scanner) κάνει την διαφορά, ειδικά καθώς αποτελεί το ιδανικό ίσως active - memory resident antimalware για Linux boxes

αν είμαι σε λάθος κατηγορία ίσως να μετακινηθεί. Επειδή όσο βολικό κι αν είναι το Putty υπολείπεται γενικά σε εμπειρία χρήσης, επειδή το κατ' εμε κορυφαίο SecureCRT είναι όμως αναλογικα πανάκριβο και καθώς σε μικτά περιβάλλοντα διαχείρισης καλό θα είναι να επιδιώκει κανείς ενιαία εμπειρία χρήσης για αμεσότερη ανταπόκριση .... mRemoteNG - το πολυεργαλείο mRemoteNG is a fork of mRemote: an open source, tabbed, multi-protocol, remote connections manager. mRemoteNG adds bug fixes and new features to mRemote.

να προσθεσω και 1-2 points ? με το περας της εγκατάστασης για security αλλά και για να λειτουργεί το σύνολο ( ειδικά σε SuPHP ) καλό είναι να τρέξουμε από τον κατάλογο του WP chown -R {user}.{group} * ή ακόμα καλύτερα για να πάρει και κρυφά αρχεία etc find -type f -exec chown {user}.{group} \; find -type d -exec chown {user}.{group} \;

έτσι είναι, μάλλον δεν υπάρχει ξεκάθαρη απάντηση αν το αναλύσουμε. ϊσως είναι προτιμότερο να ψηφίσει κάποιος με κριτήριο καθαρά την προσωπική του εκτίμηση και με βάση τις εμπειρίες του και μόνο.

Χρησιμοποιώ μόνιμα 3 διαφορετικούς browser τουλάχιστον και κανείς τους δεν είναι κάποιος από τους : IE, FF, Chrome Προτεινώ έστω και για δοκιμή να δεί κάποιος αντί για Firefox το Pale Moon ( Μακράν η πιο παραγωγική browsing εμπειρία με 100% FF compatibility), αλλά και αντί για Chrome το Comodo Dragon. Comodo Dragon, Comodo Ice Dragon και Pale Moon είναι η Αγία Τριάδα του browsing IMHO
