Need to test serial port connection
I recently bought a new UPS, and I''m attempting to use nut to monitor it. Following setup instructions everything seemed to go well until it came to testing the connection, which failed. There is just one serial connector on the computer, so I set it to monitor /dev/ttyS0. Either that is wrong, or communication is failing. I''ve been told to try minicom to monitor it,

Serial Passthrough broken in Debian Wheezy?
Hello, I just discovered a strange bug with serial passthrough in xen 4.1 on Debian Wheezy. The Dom0 has a GSM modem connected to serial port. The serial port is passed through to a DomU with options 'irq = [ 4 ]' and 'ioports = [ '3f8-3ff ]'. This worked as expected on Debian Squeeze with Xen 4.0 and Linux kernel 2.6.32 (both for Dom0 and DomU). On Debian Wheezy with Xen

working config for xen which would transfer a serial interface
Hello Can anyone share a known working config for xen which would transfer a serial interface ( add-on card preferably, mine uses e880-e887 : 0000:03:05.0 / ec00-ec07 : 0000:03:05.0 ) to a DomU ? I've been trying with the stock packages from Centos 5.5 ( fully updated) and also with gitco's 3.4.3 but after 2 days of googling and testing we still fail to access the serial

[Bridge] recent crashes? Linux kernel 2.6.18-1.2239.fc5 (Linux Fedora Core 5)
At the risk of angering the crash Gods, my sustem has NOT crashed again since I downgraded the kernel from 2.6.18-1.2239.fc5 to 2.6.18-1.2200.fc5. Given that newfound stability, and my lack of time, I'm going to put on hold any further diagnostics, until the next kernel revision is released. I have submitted a report at bugzilla.redhat.com (bug 218128). (Ah, nuts; accidentally created a

Network stops responding after some time
Hi there, I''m using the Suse Enterprise 10 RC2 along with Xen 3.0.2 on X86-64 and I''m experiencing a problem with the network. I boot into the Xen kernel and everything works just fine. I can browse the net etc. However after a while the network stops responding completely. I am not sure what causes this to happen or what triggers it. After a few hours, the network just stops
