Offhand I can't think of any (none routing) reason to hack the TTL field or any tools that use the TTL field to scan with the exception of traceroute .
If you can post the exact "netscan application" that uses TTL and why it uses it, then we can give a more accurate reply.
It is certainly possible to return bogus values of processes, including TTL. I'm more interested in understanding why you think you need to do this... thanks.

Hi All,
I know that getaddrinfo() return the multiple IP addresses (if present) for a hostname. But, I want to know how to get the TTL value for this list from DNS. I want to get this TTL value and cache this IP address list for that much time and then again go for DNS resolution if TTL expires.

I want to sort alphabetically on the first field and sort in descending numerical order on the 2nd field. With a normal "sort -r -n" it does this:
abc ||| 5e-05 ||| bla
abc ||| 3 ||| ble
def ||| 1 ||| abc
def ||| 0.2 ||| def
As you can see it ignores the fact that 5e-05 is actually 0.00005... (1 Reply)

Is there a way to setup the TTL (Time To Live) on a process. We have many ssh processes that seem to just stack up. These processes do not need a static connection all the time and it might cause problems on our servers. Does anybody know how to setup the TTL on a process? (10 Replies)

BACKUP-MANAGER-PURGE(8) backup-manager-purge BACKUP-MANAGER-PURGE(8)
NAME
backup-manager-purge - backup-manager's wrapper for outdating files
SYNOPSIS
backup-manager-purge [TTL] <options>
DESCRIPTION
backup-manager-purge is the only authorized entity that can say if an archive should be purged or not. Any tasks used by backup-manager may
have to know if an archive is deprecated (eg: the purging phase of an upload method). This tool is here to fulfill that need.
Given a time to live (TTL) and a list of archives, backup-manager-purge will return another list of archives, corresponding to the ones
that are outdated by the TTL.
REQUIRED ARGS
--ttl=time-to-live
Specify the time to live (in days) for the archives. Any archive that is older than ttl days will be outdated.
OPTIONAL ARGS
--files-from=file
A file containing a list of archives to parse, one archive per line. If this option is not used, STDIN will be used for catching the
files to parse.
RETURN
backup-manager-purge will return the list of outdated files on STDOUT, one file per line.
ERROR CODES
If an error occurs, it will print the error message on stderr and will exit with an error code greater than 0.
Here are the possible error codes:
bad command line (wrong arguments) : 10
internal error (should be reported as a bug) : 20
