cadi   | Registered | 2008-08-24 07:43:13 La prima vedere e putin cam ilogic sa te anunte prin mail (SMTP, port TCP25) cand moare serviciul de mail, adica SMTP TCP25 chiar si daca asta se face catre localhost, dar poate nu am fost suficient de atent. Exista solutii relativ simple prin care poti fi anuntat prin SMS de orice se intampla intr-un sistem sau infrastructura. Daca doriti as putea contribui cu diferite scripturi si solutii de securitate enterprise dezvoltate de mine si puse in practica.

bog   | Registered | 2008-08-25 08:24:43 Tind sa fiu de acord cu cadi, dar as fi curios ce solutii are pentru notificare prin SMS. Eu facusem un script pentru notificari printr-un portal romanesc de SMS-uri, dar din pacate respectivul site nu mai functioneaza.
