>Description:
The telnetd(8) manpage does not describe the authentication types/strings
one can use with the -X flag. I had to go look at the libtelnet code,
tracing it back to the auth_disable_name() function, then the authtype_names
variable defined in arpa/telnet.h:
const char *authtype_names[] = {
"NULL", "KERBEROS_V4", "KERBEROS_V5", "SPX", "MINK", NULL, "SRA",
0
};
Thus, the strings you can use with -X are NULL, KERBEROS_V4, KERBEROS_V5,
SPX, MINK, and SRA. These are independent of what's given to the -a
flag (e.g. -a off). I have no idea what the NULL authtype is, but the
others make perfect sense.
I ran into this situation when setting up dgamelaunch for FreeBSD, and
found that telnetd kept asking for SRA authentication when I wanted
absolutely no authentication capabilities.
This applies to both RELENG_6 and RELENG_7.
>How-To-Repeat:
n/a
>Fix:
Document the above authentication types in the manpage.
