No free space add after removing large file
Hi, On my fs I had a file of 20gb. The free space on that fs was at that time around 1gb. But after removing the 20gb file, the freespace wasn't added :-S ? What has gone wrong and how can I 'reclaim' the free space?

The file isn't deleted until all filehandles are closed. Try to install /usr/ports/sysutils/lsof and look for the open handle. E.g. lsof | grep filename Kill the process and the freespace should grow. If this doesn't work or there is no open handle try do go to single user mode an force an fsck on this fielsystem. Yes, that was the cause. I got my 20gb back :-D Thanks! ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Libz
Recently a bug was discoverd which affected various unix platforms including FreeBSD. ( ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:16.zlib.asc ) But it say it only affects the 5.x releases and not the 4. Is it true only the 5.x releases are affected?

ipfw + natd = some sites won't work :-S

Sites like Google for instance does work, but many other don't. All other protocols I guess you're using an A-DSL line with PPPoE, right? If so, see tcp-mss fix. PPPoE consumes 8 bytes of your MTU so also the maximum segment sice of TCP sessions is reduced by 8 bytes which doesn't know the machine behind the NAT box. Your NAT box has to alter the mss field in the TCP header because many sites have wrong configured firewalls which simply block all ICMP traffic, so the error from your router must fragment never reaches to originating host. So the sent packaet is too big to go over your line and the Must Fragment bit is ingnored... you'll never receive what you've requested. I'm not familar with IPFW, perhaps NATD can take care of MSS, PF does with max-mss. I'm not using an ADSL with PPPoE. But the configuration used is kinda non-standard. I'll try to explain with a little drawing: = Laptop = IP: 10.0.5.21 (/24) | | = Server 1 = IP: 10.0.5.2 |IP: 10.0.3.1 | | (ipip tunnel) | = Server 2 = IP: 10.0.3.2 |IP %external_ip% | % internet % Server 1 is a Linux box Server 2 is the FreeBSD performing the NAT Tracerouting occures without anyproblem.

Re: ipfw + natd = some sites won't work :-S
The ipfw rules standing without any other rules and '65535 allow ip from any to any' as last rule give the same behaviour. So it's not a firewall case.

Nat problem
Hi, I got my FreeBSD box set up as a NAT gateway. I got it working partialy; icmp pinging from inside to the internet works. But as soon as I try to make a tcp connection (loading a webpage or so) it just sits still! The external interface is fxp0 The internal interface is gif3 (this is a ipip tunnel) ipnat.conf is: map fxp0 10.0.1.0/24 - 0.0.0.0/32 portmap tcp/udp 1025:65000 map fxp0 10.0.1.0/24 - 0.0.0.0/32 I find it very odd, because pings travel and are natted without problems.

How safe is it to give other people user access to a jailed environment? or maybe even root... A jailed process cannot leave its jail. Unless some exploit is being found in jail itself, but that's rather unlikely. A cracker can only mess up your jail and not your entire host. So if you build 4 jails for Apache, MySQL, Squid and Postfix for instance, each of those processes will only run in its jail and cannot interact with another jail or the host. Which is more secure then just putting everything on your host. Another major advantage of jails is that you can experiment at will without touching your production enviroment. Just create a jail and install apache in the other jail. Once you are finished and it works, just amend your firewall settings and you're ready to go. If you're experienced enough I'd encourage you to use them. It can be complicated for a newbie, but if you know your way around FreeBSD and the command line, you should really use jails. Jorn. What if an exploit is found, then root should have the greatest chance to break out of the jail, or not? Should it be possible to assign root another UID in a jail (this is pretty unlikely I think), so IF it breaks out it will find hisself working as a user at the host system :-P ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
