To fix this ticket, make it give a nice helpful error message in this case.

Oh, I see that I'm supposed to not append a trailing : to the dircap. (I guess I was thinking of it as being like an SSH address with the dircap as being like the remote host identifier and the path as being like the path-within-that-remote-host part.) ``` $ tahoe ls --node-url=http://127.0.0.1:3456 URI:DIR2-RO:ixqhc4kdbjxc7o65xjnveoewym:5x6lwoxghrd5rxhwunzavft2qygfkt27oj3fbxlq4c6p45z5uneq Baldwin_2010-A_Hardware_Wrapper_for_the_SHA-3_Hash_Algorithms.pdf Chawathe_2005-A_Case_Study_in_Building_Layered_DHT_Applications.pdf Fischlin_2008-Robust_Multi-Property_Combiners_for_Hash_Functions_Revisited.pdf Koblitz_and_Menezes-Intractable_Problems_in_Cryptography.pdf Pellegrini_2010-Fault-Based_Attack_of_RSA_Authentication.pdf The_10_least-likely_and_most_dangerous_people_on_the_Internet_-_Robert_Hansen.pdf URI:DIR2-RO:ixqhc4kdbjxc7o65xjnveoewym:5x6lwoxghrd5rxhwunzavft2qygfkt27oj3fbxlq4c6p45z5uneq?t=json URI:DIR2:5nkkccw4ytkreljso5d6yxxu34:5x6lwoxghrd5rxhwunzavft2qygfkt27oj3fbxlq4c6p45z5uneq?t=json blog.html blog.xml crypto diet_research empty.html papers ``` To fix this ticket, make it give a nice helpful error message in this case.
