I'm using fwrite to write into a file stored in a normal USB flash drive. My question is: if for example a sector is damaged, does fwrite try with another one before getting me a result? If not, If I recall fwrite, will it try with a different one or with the same?

mkisofs 2.01
I do 'mkisofs -iso-level 1 -o image John Smith.txt'. Only an example. When I mount image, ls outputs john_smi.txt. So it has shorten to 8.3 and translated ' ' into '_'. This is in accordance with the manual, although it doesn't say the conversion will be done.

-iso-level level
.........................
With all iso9660 levels from 1..3, all filenames are restricted to upper case letters, numbers and the underscore (_).

However, as it did not reject the file name, it should have converted it to all upper case, it seems to me. And -iso-level 2|3 does the same thing.
Code:

How can I write to a file multiple times using fwrite without affecting the previous writes?The method shown below accepts a file name, buffer and offset. The method opens the file in reading/writing mode and writes the content of the buffer at offset.

I have a TCP connection (SSH session to some computer for example) Network suddenly goes down and drops all packets (disconnected cable, out of range). TCP resends packets again and again, retrying with increasing delays. I see the problem and plug the cable back (or restore network somehow). TCP connection finally successfully resends some packet and continues.
The problem is that I need to wait for a some timeout on point 5. I want to use my opened SSH session now and not wait for 5-10 seconds until it finds out that connection is working again.
How to force all TCP connections to resend data without delays in GNU/Linux?
I have a rather puzzling error. I recently purchased an usb external hard drive with the intent of installing Ubuntu on it. I have had great success with installing various linux flavors on usb thumb drives but I need a little larger space for engineering applications that I use. Anyway, I removed my laptop's internal hard drive and installed ubuntu 9.10 on a recently formated external hard drive. Everything worked fine at first. Upon restarting I get an error that says "no boot sector" and it asks to hit either f1 to retry. When I hit retry, Grub loads most of the time. Occasionally it does not work. Is Grub just not installing correctly? I searched for this error but I found nothing that directly applied.
View 2 Replies View RelatedWe have 20+ Redhat servers on our network and every so often our DHCP server goes down. When it comes back up we have to go around to all of our RedHat servers and restart networking manually. Other OS's (Ubuntu, Windows, etc..) will continually try to get a DHCP lease so that when our DHCP does come back up it requires no work from us for them to get back on the network. But it seems that Redhat only tries once and if it fails it never tries again. Have to go around to 20 different servers (some of them are at remote locations) is less then ideal when this happens. how we can get Redhat to continually try to get a DHCP lease like other OS's?

View 1 Replies View RelatedI was just copying files over to Ubuntu from my USB/Memory Stick Pro Duo, and apparently, I don't have enough space left to copy over files to the desktop/where ever. I had about 1 GB of hard drive left at that time,(on Windows) so I switched over back to Windows and deleted about 9GB worth of stuff. Back on Ubuntu, guessing that didn't work cause I still get the error. But I deleted some space from the Home Folder by viewing hidden files.(only about 35MB) I have a 110 GB C: Drive.

I do have one question about the latest Ubuntu server edition 9.10. Currently I am using 8.04 on a server at home and have nothing but great things to say about it.
With that being said, what would be the use case for an average joe like me to harness the new capabilities in 9.10, more specifically in regards to the new EC2 features?
