Client for OES 2 SP4 IR7a on Windows 10 1709

While trying to log in on our Novell servers using Client for OES 2 SP4 IR7a on Windows 10 1709, I was greeted with:

A required network service has not started.
Please check your error log for details.

The third reply of this post gave me a clue, simply run setup.exe one more time and reboot.

Uninstallation of IR7a still gives me error 0x80070005. The Registry settings in HKEY_LOCAL_MACHINE\SOFTWARE\Novell was accessible to me as a regular user. Maybe the client’s uninstaller is complaining about rights in the filesystem.

iobit‘s uninstaller free saved the day.

I really wish for more specific error messages.

IPv6 RDNSS and DNSSL on Cisco IOS XE

The official documentation on Cisco IOS XE for Catalyst 4500E claims this is the syntax for specifying IPv6 RDNSS and DNSSL:

Switch(config)# interface Te1/1
Switch(config‑if)# ipv6 nd ra dns server 4::4
Switch(config‑if)# ipv6 nd ra dns search list

Using IOS XE 3.10.0E, the correct syntax for DNSSL is:

Switch(config)# interface Te1/1
Switch(config‑if)# ipv6 nd ra dns server 4::4
Switch(config‑if)# ipv6 nd ra dns‑search‑list domain

Sadly, the quality of Cisco’s documentation isn’t what it was back in 2006.

Error 0x800F081F while installing .NET Framework 3.5 on Windows 10

Error 0x800F081F while installing .NET Framework 3.5 on Windows 10 might be due to corporate WSUS servers not allowing such updates.

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU in the Windows registry and set UseWUServer to 0 (zero). Restart the Windows Update service (net stop wuauserv & net start wuauserv) and retry installing .NET Framework 3.5. Set UseWUServer back to 1 (one) and restart the Windows Update service.

Star Trek Online and InstallLocation

I keep Star Trek Online installed in two separate directories. One of the copies is simply a backup which I update but never play, while the other is for playing.

Keeping these two copies updated got a bit messy after the STO launcher began recording the InstallLocation in the Windows registry.

Subsequently, I have to remove this value from the registry prior to launching the game from another location.

@echo off
reg delete "HKEY_CURRENT_USER\Software\Cryptic\Star Trek Online" /v "InstallLocation" /f

Joint Python ports in FreeBSD

I woke up this morning only to be greeted by:

# make -C /usr/ports fetchindex
/usr/ports/INDEX-11.bz2                       100% of 2150 kB  695 kBps 00m03s
# pkg version -ovIL=
devel/py27-setuptools              ?   orphaned: devel/py27-setuptools
devel/py36-setuptools              ?   orphaned: devel/py36-setuptools

As per /usr/ports/UPDATING, the solution is:

setenv FLAVOR py27
portupgrade -fpvo devel/py-setuptools devel/py27-setuptools
setenv FLAVOR py36
portupgrade -fpvo devel/py-setuptools devel/py36-setuptools
unsetenv FLAVOR

Take note of the North-American spelling.

perfSONAR 4.0.2

perfSONAR 4.0.2 is out. The system as a whole is still remarkably wedded to IPv4. Dual stack is preferred over IPv6 only. It’s tough luck if you succeed 100 % with the latter. CentOS/anaconda supports IPv6 RDNSS when configuring the DNS settings. Now, if only Cisco IOS XE would allow me to enter a domain name while configuring RDNSS. The country of Norway is (again?) a valid selection in the perfSONAR web UI. Communities disappears when you edit system information unless you also reenter your communities. Test results are only shown in the web UI when you access the node by its IPv4 address. Only IPv4 results are shown in the web UI. I’m still looking for an IPv4 block to assign to my future perfSONAR nodes. I firmly believe complete independence of IPv4 is a noble goal for perfSONAR 5.
