    ftp woes on RHEL3


    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:
    <--- MDTM
    <--- 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.

    update

    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:

    lftp sample@localhost:~> debug

    lftp sample@localhost:~> quit


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

    :drown:

    Solved

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