Seems to bo a more general problem. I just installed ftpd and telnetd. *Both* of them show exactly the same behaviour: 'ls -l' via telnet blocks also. I could get a 635 byte file via ftp, but fetching a 69294 bytes long file stalled. (This time, strace shows that ftpd is sitting in write(5, ...data..., 56262), and there are 13032 bytes in Send-Q for ftpd...) So what is this? Seems that there's a general TCP I/O problem with the software current software versions in Debian unstable. libc problem? Could a lousy network card cause this? Are there any debugging hints for me?
