Improved FTP decomposing and search mechanism Many environments have problems with malformed FTP transfers. Although not directly Check Point related, CPEthereal provides enhanced FTP features. First of all CPEthereal provides a more detailed FTP control connection decomposing than the standard Ethereal. This includes things like an explicit test for an ending and a decoding and counting of replied lines (banners in most cases): Figure 72: CPEthereal – FTP decomposing How to use fw monitor Page 58 of 70 Revision: 1.01
Because some problems (missing at the end, too long banner) are not uncommon CPEthereal also provides a function for searching such problematic packets using CheckPoint/FTP: Figure 73: CPEthereal – FTP search How to use fw monitor Page 59 of 70 Revision: 1.01
