Hello,
First of, this isn't really a BSD question.
Second, if you have an example code we might be able to help.
Presumably, you want to read a capital C with cedille? (0x80 128 Ç)
Example from: http://www.cplusplus.com/reference/clibrary/cstdio/getchar/
compiled on FreeBSD 7.2 with gcc 4.2.1 output:
Enter text. Include a dot ('.') in a sentence to exit:
sfeo
sfeo
Çsdfa
Çsdfa
besides.. 0x80!=0200
it's 0200 octal which is 128 decimal...
Might be why it doesn't work for you.
Greetz,

Re: me in ipfw rules - does it include aliases?
Tom Worster wrote: the ipfw man page says: me matches any IP address configured on an interface in the system. which suggests that if i code my rules using me then when i add an alias ip address to an interface with ifconfig, these me rules will immediately work for the newly added address as they do for other addresses. is that correct? Yes, the me keyword is expanded to whatever IP address is assigned on any interface in the system. It's updated whenever an IP address is added to or removed from an interface. Use the simple ruleset bellow to test it yourself: lab# ipfw list 00100 allow ip from me to me 65535 deny ip from any to any add alias ping alias = success remove alias ping alias = failure It's a really useful keyword, yet it's not panacea.

You may want to check if your char type is signed. If it is (and it just
happens to be 8 bits wide), (char)128 is a negative value.
I used
int ch, not char ch;
Also, just found some throwaway code that [of course] never gets
pitched, and
found the for chars = 128, it's a wide character.
while (( ch = getwc(stdin)) != WEOF)
{
if (ch == L'\xe2')
{
if ((ch1 = getwc(stdin)) == L'\x80')
{
printf(');
/* check for and swallow last of the
trio */
if ((ch2 = getwc(stdin)) == L'\x90')
{
continue;
}
}
}
else
{
putchar (ch);
}
}
I wrote the above to get rid of openoffice TXT that was still cluttered
with the
trio of wide characters that output one apostrophe.
Last night I used pdftotext to translate a pdf file; it was cluttered
with a slew of
^L's, which == '\014', and wound up with a greater slew of x80 in
more [less]
and vi. Nutshell, the file was fubar'd.

setquota + geli
hi, I would like to set some quotas with setquota on crypted disk with geli, but if I want to do so - /etc/fstab /dev/ad0s2f.eli /home ufs rw,noatime,userquota,groupquota 2 2 /etc/rc.conf enable_quotas=YES I can edit quotas by edquota, but with setquota command it is impossible ~# setquota -u -f /dev/ad0s2f.eli -bh1 stewe setquota : /dev/ad0s2f.eli is not a valid filesystem. does setquota support encrypted disks? what should I do? thank you ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Using mdconfig for swap space
Are there any advantages to using mdconfig and creating a virtual disk for swap space as opposed to having a designated swap partition? For example, I could do something like this: mdconfig -a -t swap -f /var/swap0 -s 4g swapon -a /dev/md0 to add 4G to the system swap space backed by the file /var/swap0. How would this compare to repartitioning my hard drive and adding a new 4GB swap partition? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

How would this compare to repartitioning my hard drive and adding a new 4GB swap partition? First, using -f means using -t vnode. Secondly, swapping directly to a swap partition is mildly faster than having to navigate through the filesystem layers to do swapfile based swapping. Other platforms have chosen to go with the dynamically created and deleted swapfiles (under /var/vm/swapfile0, 1, etc for example) to allow the system to adjust the amount of disk used for swapspace dynamically. With disk space costing a matter of a few cents per gigabyte nowadays, setting up a dedicated swap partition and just letting it do it's thing is much easier than trying to fiddle around with alternatives, IMHO, but you're welcome to experiment and see whether you end up with something which is actually better for your circumstances Regards, -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Your system will ideally not use swap space at all, and if it's using it a lot then it could sure use the extra ram consumed by the md drive instead of in swap. Most likely to slow your system down, not speed it up. If you're going to do anything, it's best to keep swap on a separate disk, or on the outer part of disk. -- Adam Vande More ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

For example, I could do something like this: Unless I am missing something basic here, it seems like a bad idea to me - to carve out and use up some memory to use as extra storage for processes that need more memory that you have taken away to give to swap. That is self defeating. In addition, one use of swap is to write dumps to if there is a crash. If you put it in memory, it is gone when you reboot. jerry mdconfig -a -t swap -f /var/swap0 -s 4g swapon -a /dev/md0 to add 4G to the system swap space backed by the file /var/swap0.

To repair, reboot into single user. Run the following commands: fsck -y / mount -u -o rw / rm -rf /usr/* exit This should delete the offending files.
