Hi, I'm a Professional Linux/Unix Server Administrator which is confirmed in my skills. I have 8 years of experience as Linux Administrator in hosting company in Poland. I know Linux/FreeBSD OSes, services, protocols perfect. Due to my 8-years work I have high troubleshooting with finding reasons of any potential problems. I know perfect mail severs, www, DNS servers, antyspam mechanisms, security and different backups. I installed authoritative and cachees, revdnses servers many times. I know Bind, MyDNS, PowerDNS. Even here last time I installed revdns for some ISP from Bosnia and he was glad for 5.0. I can do this for small price, I have very good contact with client, please take me, regards.
