Hi All, as a CCNA student and wishing to eventualy do CCSP, I wanted to learn all about what hackers use/do to infiltrate networks, and was introduced to dsniff at a Linux meeting, TLUG, in Tokyo, but, am having problems installing it. Please see below. checking for Berkeley DB with 1.85 compatibility... /usr/local/BerkeleyDB.4.4 configure: error: db_185.h or libdb.a not found in /usr/local/BerkeleyDB.4.4 or not configured with --enable-compat185 [root at localhost <mailto:root at localhost> dsniff-2.3]# ./configure --enable-compat185 --with-db=/usr/local/BerkeleyDB.4.4 I have installed the latest BDB, and have, as you can see, added the correct arguments for ./configure. Anyone know a workaround for this? I also tried via yum, but, nothing. # yum install dsniff Setting up Install Process Setting up repositories addons 100% |=========================| 951 B 00:00 dag 100% |=========================| 1.1 kB 00:00 update 100% |=========================| 951 B 00:00 base 100% |=========================| 1.1 kB 00:00 extras 100% |=========================| 1.1 kB 00:00 Reading repository metadata in from local files primary.xml.gz 100% |=========================| 1.2 MB 00:04 dag : ################################################## 3574/3574 Added 40 new packages, deleted 0 old in 52.25 seconds Parsing package install arguments No Match for argument: dsniff Nothing to do Cheers.
