Network drawing tools - any [good] Linux ones?
by Chris Green 15 Dec '14

15 Dec '14

Are there any Linux network drawing tools? I don't really want a full-blown Network Management solution like OpenNMS or Nagios, I just want an easy way to map my home network that doesn't require me to do it all manually. -- Chris Green

Failed to start Remount Root and Kernel File Systems
by Barry Samuels 15 Dec '14

15 Dec '14

I get the error message in the subject line every time my computer starts. It's running Debian Testing/Jessie 64 bit. There seems, however, to be nothing wrong. If I run 'systemctl status systemd-remount-fs.service' I get the following: ● systemd-remount-fs.service - Remount Root and Kernel File Systems Loaded: loaded (/lib/systemd/system/systemd-remount-fs.service; static) Active: failed (Result: exit-code) since Wed 2014-12-10 12:23:12 GMT; 6h ago Docs: man:systemd-remount-fs.service(8) http://www.freedesktop.org/wiki/Software/systemd/APIFileSystems Process: 292 ExecStart=/lib/systemd/systemd-remount-fs (code=exited, status=1/FAILURE) Main PID: 292 (code=exited, status=1/FAILURE) Dec 10 12:23:12 dataman1 systemd-remount-fs[292]: mount: /usr not mounted or bad option Dec 10 12:23:12 dataman1 systemd-remount-fs[292]: In some cases useful info is found in syslog - try Dec 10 12:23:12 dataman1 systemd-remount-fs[292]: dmesg | tail or so.

That seems to indicate a problem with the /usr mount but /usr is mounted and the options in fstab are the same as the /home /usr/local and /var partitions which are 'defaults'. The 'root' partition is mounted r/w. Does anyone understand this stuff? I don't. -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain

Firefox 34 and FlashStopper
by Bev Nicolson 11 Dec '14

11 Dec '14

Help. I upgraded to Firefox 34 but since Flashblock doesn't work with it (boo) I've got FlashStopper instead, which I have to say, is not quite as good. How can I stop it auto-playing Vine gifs? I have tried to do this pro-actively without any joy. Ta. Bev.

Low powered server machines - I've just bought one
by Chris Green 05 Dec '14

05 Dec '14

You may remember I've been mumbling and muttering about where and how to find low powered motherboards and/or complete systems for use as servers (disk NAS plus other services). I've just bought one of these:- http://www.morgancomputers.co.uk/product_detail/15265/Fujitsu-EsPrimo-P910-… I got an extra 10% off (easy, just look for Morgan promotions) so it cost me about £276. It's excellent, silent most of the time as the fans don't run unless you work it hard and, even better, the idle power consumption is only 24 watts. There's space for several more drives in the case. It would make an excellent little server machine. I'm actually going to use it as my desktop machine, it's quite fast enough for all the things I do. -- Chris Green

"Simple" awk/sed job (not simple enough for me!)
by Mark Rogers 03 Dec '14

03 Dec '14

I have some Excel files that contain some useful information (hard to believe I know!). I want to extract just that information. Somewhere in the file it will say something like "Location: Blah" and I want to capture just "Blah". I can use xls2csv to turn the XLS into text and then run that through (eg) awk. Because the XLS field in question will now be in quotes, the following gets me the whole "Location: Blah" value: xls2csv myfile.xls | grep -oE '"Location:([^"]+)"' What I want is something like this: myfile: Blah (the filename prefix is because I plan on processing about 100 files this way). I'm sure this can all be done pretty simply within awk but the rate I'm going I'm going to end up with quite a complex script, so any guidance would be very welcome! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

How to get xubuntu to 'see' an existing Windows 7 when installing?
by Chris Green 02 Dec '14

02 Dec '14

I'm trying to install xubuntu 14.10 on a computer which has windows 7 installed already. I want the xubuntu to resize the existing Windows installation and install alongside it giving me a dual boot system. I've created a standard USB stick from the 14.10 ISO file and it boots OK in the new computer but doesn't 'see' the existing Windows installation. It does see the two existing NTFS partitions OK though. Does anyone have any idea why the Windows installation isn't recognised and/or how to get xubuntu to install as dual boot? -- Chris Green

Cannot log in with (or su to) new user
by Ewan Slater 30 Nov '14

30 Nov '14

Hi All, I have a situation is driving me round the twist. I can't log in with (or su to) any new user I create. Background: I have had to take over a box built by someone else (who is no longer available to speak with). The easy answer would be to rebuild said box, but we currently have a customer on it, and so that is not an option at the moment. Problem: I need to create a couple of new users. I ssh'd into the box with an existing account, su'd to root and created the new users with useradd, and set passwords for them. If I attempt to log in as one of these users, or from the existing account (not root) I attempt to su - <username> then I get incorrect password (and I have checked what I am typing very carefully). I have checked /etc/passwd and the users have a valid shell (/bin/bash) and a valid home directory. >From root I have used passwd -u to make sure that they are not locked. I had a look at bashrc, bash_profile, /etc/profile and can’t see anything that would cause the user to be locked out. Any ideas gratefully received. Cheers, Ewan

VoIP/SIP servers
by Mark Rogers 26 Nov '14

26 Nov '14

Has anyone here got any experience of setting up a VoIP server? I have a couple of sip trunks from various places (Sipgate, Enta) which I hardly ever use but would like to start making use of. I have an account at pbxes.org which allows me to aggregate them but I'd rather run something of my own that I can learn something from. I'm therefore thinking about setting up a server running Asterisk (or similar) and some kind of web interface. Preference for Ubuntu server, Debian or CentOS in that order; most of the instructions I've found have been for CentOS (which I haven't yet tried), but the ones I have found for Debian/Ubuntu haven't worked one way or another. I'll try one of the CentOS how-to's next unless anyone here has some pointers?
