>Description:
While fetching files from remote ftp site and specifing FETCH_BIND_ADDRESS fetch does not bind it while creating ftp data connection.
strace shows:
On connecting to ftp site (login)
socket(PF_INET, SOCK_STREAM, IPPROTO_TCP) = 3
bind(3, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("83.166.48.25")}, 16) = 0
connect(3, {sa_family=AF_INET, sin_port=htons(21), sin_addr=inet_addr("130.240.22.195")}, 16) = 0
On opening ftp data connection:
getpeername(3, {sa_family=AF_INET, sin_port=htons(21), sin_addr=inet_addr("130.240.22.195")}, [16]) = 0
connect(4, {sa_family=AF_INET, sin_port=htons(53456), sin_addr=inet_addr("130.240.22.195")}, 16^C <unfinished ...>
bind ip is missing
>How-To-Repeat:
Bind ip via FETCH_BIND_ADDRESS.
Try to download from ftp (block primary ip of server)
