#
# dllogin - D-Link login
# This script is very much a hack based on the existing code, but it works for us.
#
# Thus far we have tested this on the following D-Link Switch models:
#
#   DES-3010F     - success (telnet, ssh)
#   DES-3052P     - success (telnet, ssh, ... a little slow)
#   DES-3526      - success (telnet, ssh)
#   DES-3550      - success (telnet, ssh)
#   DES-3250TG    - fail    (there's no command to print config)
#   DGS-3324SR    - success (telnet, ssh)
#   DGS-3100      - fail    (but probably not too big a job to fix)
#
# Known bugs/issues:
# - line wrap problems cause newlines within config lines at 80 chars wide on
#   some models (DES-3010F)
# - ssh can be quite slow on these units and we've even had anecdotal evidence
#   that the load on the switches can occasionally cause packet loss.  We
#   generally use telnet for this reason and all is fine.

	# dllogin - D-Link login
	# This script is very much a hack based on the existing code, but it works for us.
	#
	# Thus far we have tested this on the following D-Link Switch models:
	#
	# DES-3010F - success (telnet, ssh)
	# DES-3052P - success (telnet, ssh, ... a little slow)
	# DES-3526 - success (telnet, ssh)
	# DES-3550 - success (telnet, ssh)
	# DES-3250TG - fail (there's no command to print config)
	# DGS-3324SR - success (telnet, ssh)
	# DGS-3100 - fail (but probably not too big a job to fix)
	#
	# Known bugs/issues:
	# - line wrap problems cause newlines within config lines at 80 chars wide on
	# some models (DES-3010F)
	# - ssh can be quite slow on these units and we've even had anecdotal evidence
	# that the load on the switches can occasionally cause packet loss. We
	# generally use telnet for this reason and all is fine.
