Solaris and Windows NT Systems Administrator. The UNIX side consists of 3 E5500 servers running Solaris 7, NIS, DNS, NFS, Apache Web server, Samba, Checkpoint Firewall 1, and Sun DiskSuite RAID 5. The remaining servers are a mix of E450, Ultra 10, Sparc 5 and Netras. Workstations are all Ultra 10s. I supported 40 users. The Windows NT side had a PDC, BDC, Exchange server and approximately 20 users. I defeated a Denial of Service attack in their Cisco router.
