ethernet to serial converters with ACLs
Can anyone recommend a cheap Ethernet to Serial (RS232/422/485) converter with functionality like the Lantronix boxes .. except one that supports access lists (nothing complicated .. maybe a list of 5 approved hosts). I need a bunch of single port devices, not an access-server for a rack. I could build one out of a Pogoplug + USB/serial dongle .. (~$120 total) but would rather not re-invent the wheel. All the "secure" ones I see involve encrypting com port redirectors for the host PC .. I don't care about encrypting data in flight, I just want to restrict who can connect to the COM port on the other side of the IP device. It needs to work like the Lantronics ones do (take tcp/(port) and spit it out as rs232). Thanks, Michael Holstein Cleveland State University

We use SENA PS110 boxes ( http://www.sena.com/products/device_servers/hd_ps_x10.php ). They work very well, have various ACL features (dunno if it supports 5 named IP or not), and other configurables. Caleb

On a similar topic, any good solutions for out-of-band serial console/Ethernet solutions that use EV-DO/GSM wireless Internet?
Avocent / Cyclades boxes have ACL capability (they run Linux) and can be used with EV-DO/GSM modems. They may not be the lowest cost solution, but there is a central management system and a wide range of serial interface units from single port to at least 32 ports.

How do these compare to the Avocent/Cyclades serial console products? SNMP seems poorly implemented in the Cyclades, and if folks have good things to say about using the OpenGear stuff, it's a direction I'd want to move in. Private replies preferred to keep s/n down.

I may not understand your query, but I think the Perle IOLAN serial/terminal ethernet mini-servers can do that. They pop up on ebay in various shades of slightly-used, for around $40. Similar devices are Comtrol DeviceMasters, which are less featureful (and even cheaper). -- Henry Yen Aegis Information Systems, Inc. Senior Systems Programmer Hicksville, New York
