zamdotcom 0 Report post Posted February 1, 2011 Salam, Saya dh cuba search berkaitan dgn topik diatas..tp tak ada..kalau dah ada moderate boleh lah buang topik nih. Ada tak cara-cara nak block ultrasurf di pejabat? Kadang-kadang ada staff yang download lagu, movie, torrent dan sebagainya dan buatkan internet kat pejabat jadi amat slow sekali. Sebagai officer IT kat pejabat, saya bukanlah saja-saja nak block user-user dr download atau sebarang aktiviti harian mereka, ada juga masa sy bg user download masa lunch time dan after office hour. Buat masa sekarang ni sy cuma guna OpenDNS untuk block website-website tertentu. Jika ada otai-otai disini dapat membantu sy dan ianya amatlah sy hargai. ** office guna unifi 5mb dan Belkin wireless router. Quote Share this post Link to post Share on other sites
