| 2 # tftpd.remap -- TFTP Daemon Path Remapping | |
| 3 # | |
| 4 # This file has three fields: operation, regex, remapping | |
| 5 # | |
| 6 # The operation is a combination of the following letters: | |
| 7 # | |
| 8 # r - rewrite the matched string with the remapping pattern | |
| 9 # i - case-insensitive matching | |
| 10 # g - repeat until no match (used with "r") | |
| 11 # e - exit (with success) if we match this pattern, do not process | |
| 12 # subsequent rules | |
| 13 # s - start over from the first rule if we match this pattern | |
| 14 # a - abort (refuse the request) if we match this rule | |
| 15 # G - this rule applies to TFTP GET requests only | |
| 16 # P - this rule applies to TFTP PUT requests only | |
| 17 # | |
| 18 # The regex is a regular expression in the style of egrep(1). | |
| 19 # | |
| 20 # The remapping is a pattern, all characters are verbatim except \ | |
| 21 # \0 copies the full string that matched the regex | |
| 22 # \1..\9 copies the 9 first (..) expressions in the regex | |
| 23 # \\ is an escaped \ | |
| 24 # | |
| 25 # "#" begins a comment, unless \-escaped | |
| 26 # | |
| 27 ri ^[a-z]: # Remove drive letters | |
| 28 rg \\ / # Convert backslashes to slashes | |
| 29 rg \# @ # Convert hash marks to @ signs | |
| 30 rg /../ /..no../ # Convert /../ to /..no../ | |
| 31 e ^incoming/ # These are always ok | |
| 32 r ^[^/] /\0 # Convert nonabsolute files | |
| 33 a ^\. # Reject requests for hidden files |
