Command Line Configuration
tcprestrictions:
addresses
Set exceptions to your tcpaccessmode policy. Specify
the addresses parameter as a single entry, or a set of
entries separated by commas. Use one of the following
formats for the variable:
IPAddress, IPAddress (count), or
IPAddress[IPAddressmask]
For example:
tcprestrictions = "111.111.111.111,
222.222.222.222(5),
111.112.113.0[255.255.255.0]"
tcprestrictions:
addresses
Add the following IPv6 formats to the list of possible formats:
x:x:x:x:x:x:x:x, x:x:x:x:x:x:x:x/n
preferredciphers:
ciphers
Set the list of encryption ciphers in order of preference from
first to last. Ciphers are encoded as a two-character string,
where the first character indicates the cipher algorithm, and
the second character indicates the number of bits used. PC-
Duo Host v5.20 and later support the following ciphers:
• "A4" - AES encryption (256-bit key) with SHA1 hash
• "A3" - AES encryption (192-bit key) with SHA1 hash
• "A2" - AES encryption (128-bit key) with SHA1 hash
• "33" - Triple-DES (3DES) encryption (192-bit key) with
SHA1 hash
• "R2" - RC4-compatible encryption (128-bit key) with MD5
hash
The cipher list is a single string of concatenated cipher
strings, in order of preference from first to last, e.g.
"A4A3A233R2".
