previously, i used to run it by this: |
| 8 |
|
| 9 |
> arpwatch -i enp7s0 -m caveman@××××××.com -s /usr/sbin/sendmail |
| 10 |
|
| 11 |
but now, after some update, apparently this |
| 12 |
doesn't work any more. |
| 13 |
|
| 14 |
what seems to have changed is: |
| 15 |
|
| 16 |
* "-m" is replaced by "-w" or "-W". |
| 17 |
* "-s" doesn't specify sendmail path, but is |
| 18 |
rather only a flag to suppress "reports sent |
| 19 |
by email". |
| 20 |
|
| 21 |
if i update the command into: |
| 22 |
|
| 23 |
> arpwatch -i enp7s0 -w caveman@××××××.com |
| 24 |
|
| 25 |
then, it runs normally, but, it fails to send |
| 26 |
emails, with this error: |
| 27 |
|
| 28 |
> execl: sendmail: No such file or directory |
| 29 |
|
| 30 |
`whereis sendmail`: |
| 31 |
|
| 32 |
> sendmail: /usr/sbin/sendmail /usr/lib/sendmail /usr/lib64/sendmail /usr/share/man/man1/sendmail.1.bz2 |

questions: |
| 36 |
---------- |

|
| 38 |
Q1: what happened that caused this syntax change? |
| 39 |
e.g. is it an update from upstream? or is it |
| 40 |
a totally new app written by other devs? or |
| 41 |
am i hallucinating (pretty sure it used to |
| 42 |
work tho)? |
| 43 |
|
| 44 |
Q2: is there any better tool to monitor arps and |
| 45 |
to email me when interesting things happen? |
| 46 |
|
| 47 |
thanks a lot for your time. |
