IPv6 woes

1 Comment / Networks / By /

I’m not sure why I can’t get to the internet from my systems inside my LAN. The gateway can. Interesting: On the client box, I can’t see any IPv6 traffic leaving the except icmp. The following demonstrates: Setting up a $ ifconfig em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC> ether 00:1b:21:51:ab:2d inet 10.55.0.44 netmask 0xffffff00 broadcast 10.55.0.255 inet6 fe80::21b:21ff:fe51:ab2d%em0 prefixlen 64 scopeid 0x1 inet6 2001:470:1f07:b80:21b:21ff:fe51:ab2d prefixlen 64 autoconf nd6 options=3<PERFORMNUD,ACCEPT_RTADV> media: Ethernet autoselect […]

Overly agressive spam rejection

Leave a Comment / Mail / By /

I’ve been getting a few of these emails lately. It’s my own servers rejecting email I’m send to myself. I’m not sure yet where to adjust these settings. I’m not even sure what software is rejecting it. I suspect amavis.

ntp wasn’t running but Nagios didn’t notice

3 Comments / Nagios, Network monitoring / By /

Earlier today, I noticed the following output from a Bacula job: 24-Sep 14:14 bacula-dir JobId 38548: Start Backup JobId 38548, Job=latens_home.2010-09-24_14.12.38_31 24-Sep 14:14 bacula-dir JobId 38548: Using Device “MegaFile-latens” 24-Sep 14:09 latens-fd JobId 38548: DIR and FD clocks differ by -307 seconds, FD automatically compensating. That’s 5 minutes. It shouldn’t be varying by that much. So I started ntp. That’s when I noticed it was not being started by /etc/rc.conf. But I thought

Rebate!

Leave a Comment / hardware / By /

Back in Feburary, I ordered a 720W PSU for $150. There was a $60 rebate with it. When the PSU arrived, I promptly filled out the form and put it in an envelope for mailing. Except, I didn’t mail it. I found that envelope a few weeks ago. What the hell. I mailed it. It was already stamped etc. Today I got a $60 VISA debate card. Win. Interestingly enough, I originally bought

Sending out a URL for password reset

Leave a Comment / FreshPorts, Open Source, PostgreSQL / By / /

Quite some time ago, FreshPorts and The FreeBSD Diary both moved from clear text passwords to password hashes. As such, you are no longer able to recover your password. You had to email me. This is extra work for everyone. Let us automate this. The first, step, is a table: create table user_password_reset( user_id int not null, date_requested timestamp with time zone default (‘now’::text)::timestamp(6) with time zone, ip_address inet not null, token text

3Ware RAID issues resolved

It seems the RAID issues mentioned in recent posts have been resolved. On Friday, I upgraded the firmware on the controller and rebooted. 5 days later, the status is still OK: $ sudo /usr/local/sbin/tw_cli info c0 u0 Password: Unit UnitType Status %RCmpl %V/I/M Port Stripe Size(GB) ———————————————————————— u0 RAID-10 OK – – – 64K 195.548 u0-0 RAID-1 OK – – – – – u0-0-0 DISK OK – – p0 – 65.1826 u0-0-1 DISK

More RAID oddness

Leave a Comment / FreeBSD, hardware / By / /

After running the 3Ware diagnostic script, the status of the array went to OK. A short time later, it reverted to this $ sudo /usr/local/sbin/tw_cli info c0 u0 Unit UnitType Status %RCmpl %V/I/M Port Stripe Size(GB) ———————————————————————— u0 RAID-0 OK – – – 64K 195.548 u0-0 UNKNOWN UNKNOWN – – p0 – 104.314 u0/v0 Volume – – – – – 195.548 But this differs from the web output (image) which is rather similar
