Hi,

`dhcpcd-9.4.1-1.0` is running fine on my Arch Linux 32 box.

However, when updating to `dhcpcd-10.0.2-1.0`, I am encountering errors captured by `systemd`.

`dhcpcd` exits with the error message `*** buffer overflow detected ***: terminated`. I am attaching the output of `systemctl status --state failed`.

I did some googling but couldn't find a way to remedy this problem.

Any ideas? Seems to me to be possibly system specific; please let me know what details to provide would be helpful.

Best, Friedrich

Yes, this is a known problem with some versions of dhcp. Easiest is to simply use dhclient instead of dhcpd. Cheers Andreas
