CentOS 7, man
by m.roth＠5-cent.us 27 Jan '16

27 Jan '16

This is... odd. >From my workstation, where I'm directly logged in, if I ssh to any CentOS 7 box, as myself, and try to run man, it fails. Example 1: man dd man: cannot write to /var/cache/man/cat1/dd.1.gz in catman mode dd. Example 2: man dd man: can't chmod (null): Bad address man: can't unlink (null): Bad address dd. In all cases, if I sudo -s to root, I have no trouble reading the manpage. In all cases I've tried, selinux is in permissive mode. >From one of these boxes: ls -laF /var/cache/man/ | more total 832 drwxr-xr-x. 38 root root 4096 Jan 27 07:52 ./ drwxr-xr-x. 9 root root 105 Dec 28 12:42 ../ -rw-r--r--. 1 root root 190 Dec 28 13:18 CACHEDIR.TAG drwxr-xr-x. 4 root root 62 Jan 27 07:52 ca/ drwxr-xr-x. 2 root root 20 Jan 27 11:27 cat1/ <...> But it's the same in CentOS 6.

Re: [CentOS] Intel Xorg driver for Intel HD graphics
by Jerry Geis 27 Jan '16

> i915.preliminary_hw_support=1 Adding this to the boot - does not make it work on straight 7.2 I saw information about this - but it is mentioned on the page I included that this was no longer needed with the files listed in the link. The kernel 4.4 installs and runs fine on the NUC5C. Its the xorg-server package that is is my issue. Everything else ran fine. The problem I'm trying to solve is getting the NUC 5C to run X on 7.2. I "realize" that is all newer hardware - but if its possible it's beneficial. I just need to figure out how to compile the X server it was giving an error. Thanks, Jerry

CD-Mount on CentOS-6.7
by James B. Byrne 27 Jan '16

27 Jan '16

When I load a blank cd into the optical drive on my CentOS-6.7 workstation I am not getting any window or visible mount action on my Gnome desktop. Formerly, when I mounted a writeable media in this drive on this host I would see a nautilus style file browser window open with inducements to add files. When I visit /mnt I see nothing: ll /mnt total 0 My fstab does not seem to have much to say either: cat /etc/fstab # # /etc/fstab # Created by anaconda on Mon Sep 24 12:57:28 2012 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/vg_vhost04-lv_root / ext4 defaults 1 1 UUID=a9a7cc59-bd0c-4362-9ab6-f721e25df2f8 /boot ext4 defaults 1 2 /dev/mapper/vg_vhost04-lv_home /home ext4 defaults 1 2 /dev/mapper/vg_vhost04-lv_tmp /tmp ext4 defaults 1 2 /dev/mapper/vg_vhost04-lv_log /var/log ext4 defaults 1 2 /dev/mapper/vg_vhost04-lv_spool /var/spool ext4 defaults 1 2 /dev/mapper/vg_vhost04-lv_swap swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /dev/vg_vhost04/lv_data_disk_images /var/data/disk_images ext4 defaults 00 /dev/vg_vhost04/lv_home_byrnejb /home/byrnejb ext4 defaults 0 0 /dev/vg_vhost04/lv_var /var_new ext3 defaults 0 0 The hardware seems to be there: lshw . . . *-cdrom description: DVD-RAM writer product: DVD-RAM GH22NS30 vendor: HL-DT-ST physical id: 1 bus info: scsi@3:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/scd0 logical name: /dev/sr0 version: 1.01 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc *-serial UNCLAIMED description: SMBus product: 82801JI (ICH10 Family) SMBus Controller vendor: Intel Corporation physical id: 1f.3 bus info: pci@0000:00:1f.3 version: 00 width: 64 bits clock: 33MHz configuration: latency=0 resources: memory:d0825800-d08258ff ioport:1180(size=32) . . .

On the Asterisk host we run iaxmodem to listen to the analogue ports. Hylafax+ talks to the iaxmodem instances. This can be a network connection so it is not necessary to have Hylafax running on the host with the FXO connection. We have been running this setup with Avantfax as the UI since summer 2013 without problems.

Re: [CentOS] What to do when you've been hacked?

There is no point in deluding yourself or your clients on that point. The first thing that you must do after a breach is detected, or even suspected, is to notify all affected parties. There is an institutional bias against revelation of security incidents because of the fear of embarrassment. This is often couched in terms using the word 'premature'. Failure to disclose at the earliest opportunity is unethical and ultimately self-defeating. You will never regain trust thereafter. The second thing to do, concurrently with the first, is to isolate the affected systems from the rest of your network. If that means physically pulling wires and putting the things on their own switch and LAN segment blocked from the rest of your networks then do it. If it means shutting down the affected hosts then do it. If if means disconnecting from the network at your gateway then do it. They are in and they are looking for ways to expand their foothold. Delaying containment is pointless. The third thing to do is to involve the authorities. Unauthorised computer access is an indictable offence in Canada and the UK. It is a federal felony in the U.S.A. If you have an incident then report it. That means you should have computer emergency response contact information and reporting protocols already in place. Now, with your clients and the authorities notified and the suspect systems isolated, you begin to map out your recovery strategy. The basic bones of which you have already written down and implemented in your backup and disaster recovery plan. A security breach is a disaster. You need to start with that point clearly in mind and proceed on that basis. Once corporate and client services are restored on clean hosts and reconnected to the Internet then begin your investigation. Use your AIDE and syslog records to determine the point of entry, the length of compromise and the extent of penetration. If possible identify the nature of the attackers and their target. Where possible keep the compromised hosts' disk drives unaltered for further technical analysis. Where warranted bring in forensic investigators to examine them. It will likely prove impossible to positively identify them but you should be able to glean some inkling if this was a targeted breach or an opportunistic one. If the former then they will be back and you will need to consider how to deal with the next assault. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail James B.
