I've tried using firefox to download the image as well as wget. I will start the download and come back sometime later and discover that I've been logged out. I have also observed that running firefox 3.6.4 (firefox-3.6.4-8) will sometimes cause my X session to freeze up requiring me to login from another system and kill the X server in order to use it again. This is a problem that I have only recently observed. Another thing I have noticed is that quite often while doing the download the destination file will stop getting updated. The time stamp of the file will not change and the file size will not update even though when I run wireshark it shows the connection to ftp.redhat.com is still live and packets are being received and the sequence number in the packets are changing which implies data is arriving but not going to the file. I have been trying to download the RHEL 6 Beta iso images since last Thursday onto my RHEL 5.4 system and have not succeeded yet. Has anyone else seen this issue while trying to download a large file? Any help in trying to determine the cause and if possible a solution to the problem is greatly appreciated.
