I got the following error: a = read.csv("mat.csv") b = as.matrix(a) tb = t(b) bb = tb %*% b dim(bb) ibb = solve(bb) bb %*% ibb > ibb = solve(bb) Error in solve.default(bb) : system is computationally singular: reciprocal condition number = 1.77573e-19 > Are there any ways to find more information about why it is singular?

Hi, I think I am not getting WINS to work correctly in my network. Here is the setup, any advise would be greatly appreciated: 3 Samba servers: 1. IBBFILE (Old samba server 2.2.8) being replaced by GT-IBB. I have moved about 70% of the users already. 2. GT-IBB (New samba server to replace IBBFILE samba-3.0.10-1.4E RHEL) 3.

I don't know why, but for my case, I reduced the tinc topology from a complex one(which provide layered redundancy) to a very simpled one(one connection), and that connection drop disappeared. Later, let me draw the topology and share the config to you to see if there's any findings of the cause. Guus Sliepen <guus at tinc-vpn.org>于2017年9月14日 周四上午3:20写道： > On Wed, Sep 13, 2017

...any year ago, I built myself 2 file servers (5 disks enclosure for data, 2 disks enclosure for the OS) on a computer. It was running on Debian 7.11 for years without an issue and I was getting 75MB/95MB when transferring file from it to a Windows client, all having a 1gbs network card. https://i.ibb.co/N618Z4W/Debian-7.png However, after upgrading to Debian 8 and more recently Debian 11, I keep noticing a? huge performance drop. The near 100 MB drop to a roller coaster of between 25MB and 60 MB/S, the average being 40 MB/S I've been googling trying various 'performance' tweak&...

Hello dovecot list, I'm in the middle of creating a plugin for observium[1] and would like to have it create[2] statistical graphs of my dovecot server [3]. The current state can be found here: https://image.ibb.co/efOO9a/dovecot.png However for visibility purposes it doesnt make sense and have observium plot two data sources with different orders of magnitudes right into one graph. So I'd like to ask for your valuable recommendations as for: - What kind of data should be graphed? Global stats or o...

Hi Rowland I am trying to follow the article but am having the error. That's why I am trying to clean up this bad subdomain. I don't know if these lists allow image attachments. So I uploaded a screenshot here. https://ibb.co/Ct3BLjL I built a new domain for this problem in our lab. The domain listed with #1 is the one created by the domain provision. However the one listed with the #2 is an example of the sub domain that I need to delete. As is pointed out in the article, in our live environment there is a subdomai...

I have just finished replacing a client's Windows / Exchange / IIS setup here with Samba / [Postfix, UW Imap] / Apache and I've run into an issue. In this setup, Samba acts as PDC, so there are NO WINDOWS SERVERS - only win clients. One of the apps that they run seems to explicitly require that the user own the folder that they are saving to. In their prior setup, this was easy, as
