Re: .sh script code to determine IPv4 or IPv6
I have some scripts that do fairly crude IPv4/6 validation testing. It is generally assumed that the input is coming from someone who knows what they are doing, but even the best of us have fat fingers sometimes :) Having standardized routines for something like this is great!

You've configured "one" and "two" and "three" in your jail_list, but quite
oddly...
You have not defined "jail_one_*" or "jail_two_*" or "jail_three_*".
I'm extremely confused as to how your jail even started!

I see where you are defining a hostname, but not a jail name. Jail name cannot
contain the

logger logs to syslog, so unless you have user.notice logging to /var/log/testing.log this will probably not do what you are expecting. Have a look in /var/log/messages for something like this. Jun 27 16:38:03 xxx-hostname base_http_access: /var/log/testing.log Otherwise, you may want to setup /etc/syslog.conf to log one of the local facilities to /var/log/testing.log with something like this: local6.* /var/log/testing.log you will need to touch /var/log/testing.log and restart syslog, then change your script to something like this: echo "Testing, testing, testing" |/usr/bin/tee -a /var/log/httpd-access.log |/usr/bin/logger -t base_http_access -p local6.info Don't forget to update newsyslog.conf to rotate your new testing.log -Markham On 13-06-27 10:29 AM, Paul Schmehl wrote: > echo "Testing, testing, testing" |/usr/bin/tee -a /var/log/httpd-access.log > |/usr/bin/logger -t base_http_access /var/log/testing.log > > This writes to the httpd-access.log but does not write to > /var/log/testing.log.

Re: cksum entire dir??
As long as you are not moving files across mount points, you could always do something like this: cd $SOURCE_DIR && find . -print | cpio -dplm $DEST_DIR rm -rf $SOURCE_DIR That will create hard links from one directory to the other so you don't have to worry about any file corruption since the data is never actually moved around on the disk. It should also be a whole lot faster than actually moving or copying the data and you don't have to worry about running out of disk space half way through a copy. -M On 12-09-11 3:38 PM, Gary Kline wrote: > I'm trying to checksum directories as I move them around. > ive read the man page for sum and cksum ... or maybe skimmed > them. no joy. anybody know of a utility to do this?

Re: gpart and mbr give "no operating system" message at boot.
Thanks Warren! I was always under the impression that partition 3 was not to be touched as the "raw" partition, so figured it was best left alone. I was mostly concerned with installing MBR so it would still be compatible with sysinstall, although I can't really think of a terribly good reason not to go GPT. Installing the bootcode gets me a step closer, but is now puking at the loader. I'm not sure if this is because the bootcode is coming from and 8.1 install, but at this point I'm pretty much out of time and out of patience for this, since it is something of a bandaid situation anyway.

gpart and mbr give "no operating system" message at boot.
I am trying to partition a disk to be used as the primary boot disk for a FreeBSD 8.3 installation using gpart to install an MBR partition. The system is an existing FreeBSD 5.2.1 system at a remote location (ie impossible to boot from CD/netboot/etc), but has no data of value. To do this I am copying /boot and mfsroot.gz from an mfsbsd iso image to boot to an MFS live system so I can wipe the drive and do a clean install of 8.3. After booting to the MFS I do this: dd if=/dev/zero of=/dev/ad2 bs=1m count=1 gpart create -s mbr ad2 gpart add -b63 -t freebsd ad2 gpart create -s bsd ad2s1 gpart add -i1 -s 1g -t freebsd-ufs ad2s1 gpart add -i2 -s 1g -t freebsd-swap ad2s1 gpart add -i4 -s 2g -t freebsd-ufs ad2s1 gpart add -i5 -s 1g -t freebsd-ufs ad2s1 gpart add -i6 -t freebsd-ufs ad2s1 gpart set -a active -i 1 ad2 gpart bootcode -b /boot/mbr ad2 newfs /dev/ad2s1a newfs -U /dev/ad2s1d newfs -U /dev/ad2s1e newfs -U /dev/ad2s1f followed by a sysinstall and some configuration. When I reboot I get a message that says "Operating system not found" and the system hangs. If I follow the same procedure but create a gpt partition it works swimmingly. I am OK with using a gpt partition if needed, but for the sake of curiosity I would like to know why I can't make the MBR partition partition work.

8.1 broken inter-jail IP communication
Good Day, I am encountering an occassional problem under FreeBSD 8.1 where two jails on the same server cannot reach each other after a reboot. The Jails are running a mail server and ldap server, respectively and each has it's own IP address. The problem manifests itself after a reboot of the server. After both jails have started the mail server is unable to communicate with the ldap server. From inside the jail, a host unreachable is returned when trying to connect to the ldap server. I have tried clearing the arp-cache and route-cache from the host and restarting both jails, but the problem persists. The arp table from the host server (outside the jail) shows an "(incomplete)" entry for the mail server when this is happening. I was able to ping the mail IP address from the host server and the incomplete entry disappeared and, as expected, there was no longer an arp entry for the mail server and communications between the two jails was restored. Unfortunately I have had difficulty recreating this scenario in a test environment and it only pops up occasionally in the field. And while this workaround is suitable, it is a bit of a PITA and I would like to know if this problem can be resolved. So, I am wondering if anyone has some insights into what might be at the root of this problem and what might be useful data to collect when this problem is happening to help pin down the source of it. Unfortunately, when service fails, I don't have a lot of time to poke around at things as I need to do whatever I can to get it back up a quickly as possible, although I am continuing to try and recreate this scenario in a test environment.
