ftp woes on RHEL3

[whitey]

Here is the problem that I'm having, I've got a RHEL3 box that has vsftpd installed and I just upgraded to kernel 2.4.21-57.EL, was running 2.4.21-50.EL issue has been on both versions. When I login via ftp I authenticate fine, I can switch to passive mode, but when I try to download a file or pull up an directory listing the client freezes. I've tried this on multiple clients, and it always ends the same way.

lftp rack@x.x.x.x:~> ls
---- Connecting to x.x.x.x (x.x.x.x) port 21
<--- 220 (vsFTPd 1.2.1)
---> FEAT
<--- 530 Please login with USER and PASS.
---> AUTH TLS
<--- 530 Please login with USER and PASS.
---> USER rack
<--- 331 Please specify the password.
---> PASS XXXX
<--- 230 Login successful.
---> FEAT
<--- 211-Features:

<--- REST STREAM
<--- SIZE
<--- 211 End
---> PWD
<--- 257 "/home/rack"
---> PASV
<--- 227 Entering Passive Mode (x,x,x,x,225,109)
---- Connecting data socket to (x.x.x.x) port 57709
---- Data connection established
---> LIST
<--- 150 Here comes the directory listing.
<--- 226 Directory send OK.

**this is where it stops, it accepts that there is a directory being sent, but it never receives it**

I've uninstalled and reinstalled vsftpd, so it is up to date and has a clean config file. At this point I'm pretty sure this is system related, but I don't know where to go from here.

Yo guys,

I'm still testing this and found that I could login to ftp from localhost and I was successful in downloading a file:

Maybe this is something networking related, but I'm stumpled.

I ended up updating the kernel to the latest patch, and it now seems to be working fine.
