hey,

In that case, shouldn't axel give an error message on the lines of "file doesn't exist" or something similar? Segfaulting is not the expected output IMO. Does this mean axel doesn't handle 300 HTTP codes?

Ankur

looks like the server is returning a 301 to a FTP site where the file no longer exists. you might want to try http://distro.ibiblio.org/pub/linux/distributions/tinycorelinux/2.x/release/tinycore_2.11.iso

Hope that helps. This bug still persists. That's one file that axel can't download..
