Hi everybody, I have problem with udp-receiver, it is unable to store files larger than 2GB. I have read older post and found some work around (udp-receiver > image.gz) but this did not work either.
my config is: CPU P4 2,4GHz, RAM 512 DDR, HDD WD 120GB, NIC RTL8139 (8139too driver), i run debian woody orignaly (2.2) kernel but i upgraded to 2.4.18-686, i use udpcast 20030831, partition where i store image i big enough and has reiserfs
i administer small lan, about 15 winxp boxes
any hints?
thanx, der3k
Using redhat9 on a Pentium 3 machine (I don't have the specific config) I was able to store files up to at least 5GB, using only
$ udp-receiver -f filename
Also, we restored zipped backups of entire partitions (zipped files, original size up to 10GB) like this:
# udp-receiver -p "cat" | gzip -dc | dd of=$OUTPUTDEVICE
Maybe you can use a modified version of that line.
As for your problem: what exactly happens? Are you getting any kind of errors?
Hope this helps

Hi Richard,
Yes, I can help, I can help!!! I'm sure you'll get a few responses on this one, but the problem isn't UDPcast, it's your file system. You're file system is probably ext2 which can't handle large file sizes. I'd recommend moving your file system to ext3. I forget the exact command, but checking out the man pages for mkfs for mke2fs will tell you how to do that.

ext2 isn't limited to files of 2G. from the limitations section of /usr/src/linux/Documentation/filesystems/ext2.txt:
Filesystem block size: 1kB 2kB 4kB 8kB
File size limit: 16GB 256GB 2048GB 2048GB Filesystem size limit: 2047GB 8192GB 16384GB 32768GB

Oops. Sorry about the empty email... Achem!
Anyway, I was going to say, we had the same problem, but we fixed it by piping through dd. Our problem seemed to be on the sender though... here's what we did...
udp-sender --nokbd --max-bitrate 80m --pipe "dd if=/home/image/disk.img"
The nokbd and max-bitrate are for unrelated problems...
Maybe some simler dd trickery would help your problem.

Hi everybody, today i tried on my reiserfs partion:
# dd if=/dev/zero of=test bs=1024 count=10240000
which should create obout 10GB big file and i got such a result:
dd: writing 'test': File too large 2097153+0 records in 2097152+0 records out
newly created file is 2GB big
so now i see that there is no problem with upd-receiver but with my fs or kernel
thanx for your hints
Richard
good article explaining where is problem with creating big (<2GB) files on linux is here http://www.suse.de/~aj/linux_lfs.html
