Machine is FTPing into Walla Walla University.
Came in this morning and noticed a connection to
So I fired up the terminal and tried to manually connect to this address:
[nealosis@LISAXPS410FEDORA ~]$ ftp 220.127.116.11
Connected to 18.104.22.168 (22.214.171.124).
220-| Welcome to the Walla Walla University FTP server |
220-| Please send suggestions/questions/comments/etc. to |
220-| firstname.lastname@example.org |
220-| Please see /FAQ for questions regarding this FTP server |
Name (126.96.36.199:lisa): anonymous
331 Please specify the password.
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
I was able to log in as anonymous and look around. Looks like these are linux update packages on this server and if that's so then I guess its ok.
Is it standard practice for Linux workstations to establish anonymous FTP connections behind the scenes like this?
Maybe the connection was dropped before the lsof? --run netstat again
netstat -tn | grep -i 21
tcp 0 0 192.168.2.109:39879 188.8.131.52:21 ESTABLISHED
tcp 0 0 192.168.2.109:53421 184.108.40.206:21 ESTABLISHED
tcp 0 0 192.168.2.109:44583 220.127.116.11:21 ESTABLISHED
Not sure what to do now. How do I track down what process is making these ftp connections? Even if this connection is legit, I'm not comfortable with any process making anonymous connections to remote servers without rendering a dialog or something to indicate that what's going on is legit.
Ok, so it looks like this is some yum process backend. I wonder if there is a setting where I can diable this phone-home action? If I want to update yum then I use 'yum update'; I don't need (or want) it phoning home on its own.
