Chere tous,

    I have a question about curl usage with the --interface option and
virtual NICs.

This works,
r3k-app56:/usr/local/bin # curl -v -s -S -k --interface eth0 --ftp-pasv
--ftp-skip-pasv-ip --ftp-ssl --ftp-ssl-ccc -u 'ACC50506:9f2o82sAZe'
ftp://1.2.3.4:21
* About to connect() to 1.2.3.4 port 21 (#0)
* Trying 1.2.3.4... Bind local address to 10.254.177.90
* Local port: 39694
^C

...But this does not,
r3k-app56:/usr/local/bin # curl -v -s -S -k --interface eth0:1
--ftp-pasv --ftp-skip-pasv-ip --ftp-ssl --ftp-ssl-ccc -u
'ACC50506:9f2o82sAZe' ftp://1.2.3.4:21
* About to connect() to 1.2.3.4 port 21 (#0)
* Trying 1.2.3.4... Bind local address to 10.254.177.92
* SO_BINDTODEVICE eth0:1 failed
* Local port: 45386
^C

Curl certainly can obtain the correct IP address from the virtual device
as shown in the second example:
* Trying 1.2.3.4... Bind local address to 10.254.177.92
but then is unhappy
* SO_BINDTODEVICE eth0:1 failed

I have tried putting the virtual eth0:1 inside:
'eth0:1'
"eth0:1"
eth0\:1
and these all fail with the same message.

Can Curl deal with virtual eathernet cards, or is there a hack for this?

Best regards, S.

PS. When the NIC is replaced with the IP on the interface then it does
not complain, but I would rather use the actual interface.
r3k-app56:/usr/local/bin # curl -v -s -S -k --interface 10.254.177.92
--ftp-pasv --ftp-skip-pasv-ip --ftp-ssl --ftp-ssl-ccc -u
'ACC50506:9f2o82sAZe' ftp://1.2.3.4:21
* About to connect() to 1.2.3.4 port 21 (#0)
* Trying 1.2.3.4... Bind local address to 10.254.177.92
* Local port: 33130
