IP addresses listed under root directory: why are they there?

[doremifajb]

Hello ! I just noticed that a bunch of IP addresses with ports: looks like all mine, are under the root of openwrt. Looking like this:

-rw-r--r--    1 root             0 Apr 24 10:38 192.168.1.220.443:
-rw-r--r--    1 root             0 Apr 24 10:38 192.168.1.220.7:
-rw-r--r--    1 root             0 Apr 24 10:38 192.168.1.220.8080:
-rw-r--r--    1 root             0 Apr 24 10:38 192.168.1.220.80:
-rw-r--r--    1 root             0 Apr 24 10:36 192.168.3.205.60110:
-rw-r--r--    1 root             0 Apr 24 10:36 192.168.3.205.60111:
-rw-r--r--    1 root             0 Apr 24 10:36 192.168.3.205.60112:
-rw-r--r--    1 root             0 Apr 24 10:36 192.168.3.205.60114:

They all have size zero, are they empty files? It seems that it has something to do with the fact that I was trying out tcpdump around April 24th, I see from my old posting that I did

tcpdump -i eth0.16 -n host 192.168.1.220 and 192.168.3.205

Did it create these empty files ? What should I do with them?

/root/ is normally empty on OpenWrt, although some applications may leave config files there (e.g. htop). You can safely delete whatever you like there, the most likely cause for those files might be a failing stdio/ stderr redirect (either from your manual command invocation or some wrapper script).

Thanks for your reply! OK, I will delete them. Perhaps tcpdump had "failing stdin/stderr" then.
