hplips
by mark 26 Feb '19

26 Feb '19

Yeah, about that... Back in '12, we got a nice HP poster printer. They don't support Linux, but a co-worker got the .ppd out of the Mac support file. I tried it, then I looked at the file in vi... and found it *only* supported the 24" printer, *not* the 44" printer that we had. Well, we just bought a replacement, since the old printer was EOL'd. This time, I went to hplips, d/l and built the current one, and sure enough, there's a .ppd for the DesignJet Z9. Any bets on what I found? No? There was *NO* support for the 44" printer. I saw *one* setting for something 30x42 (the 100' roll of paper is 42" wide). I joined and tried asking about that on the hplips site. That was last week. Not a single response. HP no longer does software support for their printers (I got that from the engineer - we do have contract support). Had a friend d/l and install the Mac ps driver... no .ppd. Anyone know someone who's involved with hplips? Otherwise, I'm going to have to spend half a day or a day hacking the damn .ppd. Btw, the server it's attached to is C6. One of these days I'll upgrade it to C7, but the *only* think it's used for now are these poster printers. mark

Policy issue: C7 and motion
by mark 25 Feb '19

25 Feb '19

Not sure who's package let an error slip in, but I don't believe I've had this issue before: SELinux is preventing /usr/bin/motion from map access on the chr_file /dev/video1 Yes, that should be allowed by default. mark

Does anyone know if Geany 1.34 is headed to one of the repositories? I am running version 1.31 and interested in the 1.33+ since the markdown plugin has apparently been updated.

Nvme m.2 disk problem
by Alessandro Baggi 24 Feb '19

24 Feb '19

Hi list, I'm running Centos 7.6 on an Corsair Force MP500 120 GB. Root fs is ext4 and this drive is ~1 year old. System works very well except on boot. During boot process I got always a file system check on nvme drive. Running smartctl on this drive I got this: === START OF SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED SMART/Health Information (NVMe Log 0x02, NSID 0x1) Critical Warning: 0x00 Temperature: 41 Celsius Available Spare: 100% Available Spare Threshold: 1% Percentage Used: 1% Data Units Read: 5,355,595 [2,74 TB] Data Units Written: 5,826,517 [2,98 TB] Host Read Commands: 67,978,550 Host Write Commands: 75,422,898 Controller Busy Time: 32,863 Power Cycles: 811 Power On Hours: 2,813 Unsafe Shutdowns: 317 Media and Data Integrity Errors: 0 Error Information Log Entries: 177 Warning Comp.

(48 entries not shown) I noticed that Unsafe shutdowns increased rapidly and I don't know why there is an unsafe shutdown. Every 3/4 boot this value is increased by 1 and I don't know why. I can't find any errors on system logs. Can someone point me in the right direction? Thanks in advance. Alessandro.

Python 2.7.5 and GnuPG sig verify
by Michael Peters 23 Feb '19

I asked on stack overflow but I'm trying to boost the signal. I don't normally program in python but I can usually figure out how to do it when I need to, but I'm just stumped, there clearly is something I'm not understanding. It's a CentOS 7.6 box and python install I'm trying this on. Thanks for any suggestions, I can't figure out why it isn't working. https://stackoverflow.com/questions/54841911/python-gnupg-verify-file -- *Notice*: Gmail is owned by Google, a company that made its fortune in content indexing and user tracking.

thunderbird issues
by mark 22 Feb '19

22 Feb '19

Just updated t-bird, and once again, it wants to open a completely new browser, other than using the running one. I started searching, and found something about editing the config, and for the first one of the two they said to change, I find this: network.protocol-handler.app.https;/usr/lib64/thunderbird-3.1/open-browser.sh %s a) there's only /usr/lib64/thunderbird, and I'm on 60.something. Is this in my config as a user? is this something that should go away? Please don't tell me I have to create a whole new t-bird configuration.... mark

iptables 2 firewalld
by mark 22 Feb '19

22 Feb '19

Y'all may remember me fighting this a few weeks back. I did finally succeed, and thought that my awk script might be helpful to others. Yes, it's really simple, it uses the build-in FORWARD chain. The line where I skip the definition of those chains is because it *is* built in. To use it, I did an iptables-save on the firewall that's currently in use, changed the physdev devices to match the ones on the new box (I *loathe* that idiot varying name convention, it is *not* helpful, and then ran it through this script. I piped the o/p into a file, then sh scriptname did the actual install. Following that, I did firewall-cmd --reload, and all was wonderful, and I could ping the system inside the firewall, and from the subnet in our building (the new one's in the datacenter), but not from anywhere else, so the rules worked. Note that I did the work, I work for a US gov't federal contractor, so this was done on tax dollars, and should be free of any encumberment. Hope it helps, folks. BEGIN { priority = 1; } { if ( $0 ~ /^-A/ ) { if ( $2 ~ /^INPUT|^FORWARD/ ) { next; } else { rule = substr( $0, index($0, $3)); } print "firewall-cmd --permanent --direct --add-rule ipv4 filter FORWARD " priority++ " " rule; } } mark

Changing UID numbers
by Bill Gee 21 Feb '19

21 Feb '19

Hello everyone - I have a question regarding UID and GID numbers. First, a bit of background: Yesterday I suffered a complete power failure. My UPS batteries ran everything for an hour, but that was not long enough. My CentOS6 server shut itself down, just like it should. When the power came back up, the perfectly running server was no longer working. The boot hard drive was complete toast. ARGH! OK, I have backups and spare hard drives. CentOS6 is getting a bit long in the tooth. I have to reformat and reinstall CentOS before restoring backups anyway, so I decided now is the time to move to CentOS7. I chose to rip the bandage! The CentOS6 installation was quite old. Back in those days the default UID for new users was 500. That's how I set up my user account on the machine. My main workstation is Fedora 29, but it started life MANY cycles ago and also has my UID=500. That all works nicely with the nfs share coming off the server. On newer builds I have wrestled with having my UID=1000, as is the new standard. File permissions on the nfs share were never quite right. It was not irritating enough to make me desperate, but it was annoying. I got around it with a lot of 777 and 666 permissions settings. I looked at rpc-idmapd but was never able to make it work. Now with CentOS7 my server user account is UID=1000. The nfs share is on a separate drive (not the one that failed), and all of the files on it are still owned by UID=500. It works from my main workstation, but is really unclean. So now the questions: What will it take to change all the files to the new UID? What will it take to change my main workstation to the new UID **without** having to create a new user account? I think I can do this in two steps. 0) backup, backup, backup! 1) On the server - use "find" to find all files owned by UID=500. Chown them to UID=1000. Repeat for gid=500. 2) Tricky - On the workstation, boot to non-gui. Login as root. Repeat the same two "find" commands as on the server. Edit the /etc/passwd and /etc/group files to show the new UID and GID numbers. What does this do to the shadow files? Are there other places I need to look for the UID and GID numbers? Thanks! -- Bill Gee
