I am a consultant at Notes Development AG. We specialize in applications development and consulting services for IBM Lotus Notes and Domino. Since Domino runs perfectly well on Linux servers we always run one or more internal Linux servers in test, production, and development environments.
I use SecureCRT® for the maintenance of our internally and externally hosted Linux-based Domino and web servers. I also use SecureCRT to access routers and firewalls for command-line based management. SecureCRT is easy to use and it simply works and there is nothing complicated to deal with. Adding access for a new host is just a click away, and if you need SSH—and I always do—just select it and you are finished.
SecureCRT has never failed me. I recently had a problem with UTF-8. The VanDyke support team answered promptly and to my surprise, the version I was eligible to upgrade to for free already contained the UTF-8 support I needed ( I decided to pay for an upgrade to the very latest version anyway). I have yet to find anything that I need missing in version 4.1, but I'll update to 5.0 as soon as it is available in official release for the tabbed user interface and named firewalls. I used terminal emulators for many years before I purchased SecureCRT and I have never seen a better and more reliable product for this purpose.
I often need to upload configurations and install files from my PC. With SecureCRT, this is no problem. While others are messing around with FTP configurations and security settings I simply login to Linux, start "rz" and a dialog appears in SecureCRT that allows me to select the files to upload from my PC.
Even though Zmodem file transfer is good enough to get my job done, I am currently evaluating SecureFX® and I am very happy with what I have seen so far. SecureFX supports SFTP, which is in some cases the only method our customers permit for file transfers over the internet (most of our customers are large corporations with strong security policies and they've disallowed the use of FTP for quite awhile). Since I would like to have all my file transfer needs covered with one single solution, I can't think of anything better than what is offered by the tight integration of SecureFX and SecureCRT (FTP, SFTP, ASCII, and Xmodem/Zmodem).
