What command could I use to get the last line of an output?
Heres why...
I use this command:
netstat -plan|grep :80|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -nk 1
I would like to get just the last line of the output, the output looks like this:
The reason is because I'd like to get that last figure to place into a file on a certain time period (through a cron), which will then be graphed with PHP.
We have a plesk server running on a Ubuntu 14.04.2 LTS machine. We check the state of the mailqueue with nagios, executing the "mailq" command. After the AutoInstaller upgraded our installation from 12.0.18 update 38 to 39, we noticed, that the nagios check failed.
After investigating a little bit, it seems that we found the problem:
When I enter "mailq" in the shell, the command is executed and gives me an proper output. But when I try to execute the command with its full path "/usr/bin/mailq" nothing happens, and I have to cancel with [ctrl]+[c]. The which-command delivers exactly the same path as written above...
I have an issue with running of the php-scripts. It runs via Cron (as it consumes a lot of memory), after aprox. 10 minutes after the start-time of the script the following error appears in the error-log file (path - /var/www/vhosts/system/subdomain.domain.tld/logs/error_log)
[Tue Feb 17 19:46:57.003326 2015] [fcgid:warn] [pid 28629] (104)Connection reset by peer: [client XX.XXX.XXX.XXX:48450] mod_fcgid: error reading data from FastCGI server [Tue Feb 17 19:46:57.003368 2015] [core:error] [pid 28629] [client XX.XXX.XXX.XXX:48450] End of script output before headers: Name_of_the_script.php
For a very strange reason another PHP-script, that has the same code, but just runs less arrays, and therefore consumes less memory and can be run via browser - works perfectly from both browser and the cron. The php.ini for this domain set up correctly (see the attachment)...
I'm using this script as a cron to generate DKIM keys for the domains I have. It's an easy script. And it does it's job just OK. I have the necessary software installed and configured.
The way it works is:
The script check if the domain in queue has a record for it. If it doesn't, OpenDKIM generates a one time DKIM record for mail._domainkey that I am entering to my dns records for all the domains I have.
After creating the DKIM record, it checks and deletes mail._domainkey records if there's any. Then adds the generated DKIM to plesk dns zones and disables/enables greylisting to create the appropriate dns entry.
If it does have a DKIM recors on the hdd already, then it removes
mail._domainkeyand TXT o=-entries.
After that it basically adds the already generated DKIM record and it disables/enables the greylisting for each domain in order to recreate "TXT o=-"
Up till here, it works fine. I can see these entries when I check the DNS Settings. They are there.
But whenever I run this script either via cron or manually, I get an error message on my panel: (You can check the screenshot as well)
Code:
Warning: The DNS zone was modified. If you would like to apply DNS template changes to this zone, either click the 'Apply DNS Template Changes' button on this page or choose the 'Apply the changes to all zones' option in Server Administration Panel > Tools & Settings > DNS Template Settings > Apply DNS Template Changes.
And unless I manually click "Apply DNS Template Changes" for EVERY SITE it doesn't go away.
So, I was wondering, is there a way to scriptize that command? Or how to prevent it?
This is the command I use to generate DKIM and add it to Plesk database, also if any such record exists, delete and re-write it:
Is there a command line way of removing Plesk backups?
I'm looking for the command line equivalent of these steps: Log into Plesk as the server admin > "Tools & Settings" > "Tools & Resources" > "Backup Manager" > check a backup and click "Remove".
We have a script that copies the contents of "/var/lib/psa/dumps/" to Amazon S3 for long-term storage of backups. It runs nightly after a scheduled Plesk backup. Once that script completes successfully, we'd like to delete the Plesk backup to free up disk space. We have Plesk's "Maximum number of backups in the repository" set to 1.
But Plesk appears to keep that backup around while creating a new backup (which makes some sense). This is causing us trouble because the server does not have enough disk space for two backups. As a temporary solution, I'm manually deleting the backup each day through the Plesk admin, but would like to automate it if possible. If automation is overly complex/risky, we'll look at upping our disk space instead.
I have a subscription and I'm able to switch the subscription to a given service-plan, but I'm unable to sync the subscription with the plan, using the CLI. These are my commands:
result => The subscription <domain.com> is now associated with the service plan Hosting..When watching the webinterface in Plesk, I see the domain is "connected" to the service plan, so far so good. However, I notice that the subscription is not synced.
Back to the CLI, I've tried some combinations, but I can't get the subscription synced. The webbased interface keeps telling me that the subscription is unsynced. Here is what I've tried:
And I also unlocked it (just in case it was locked) like so: /usr/local/psa/bin/subscription --unlock-subscription <domain.com>
The funny part is that the CLI tells me: "Subscription <domain.com> was synchronized with the associated service plans." but unfortenately it's not if I look through the GUI. Only if I click the sync-option webbased the subscription get synced. we have to transfer over 1000 domains and need to sync these domains with a given service-plan.
After successful upgrade PHP, and not successful with ioncube i get:

Although running >> /usr/local/psa/bin/dns --info dev.sname.c002.aname.domain.com >> shows the 'ecz1' TXT record exists for "dev.sname.c002.aname.domain.com" : ... ecz1.dev.sname.c002.aname.domain.com. TXT ecz1
[Code] ....
The issue can be caused by extra spaces in the TXT record:
Code: [root@a10-52-143-28 ~]# /usr/local/psa/bin/dns --add dev.sname.c002.aname.domain.com -txt 'ecz1 ' -domain ecz1 SUCCESS: Creation of DNS record in Domain 'dev.sname.c002.aname.domain.com' complete.

In the following example I have 3 such TXT records with 3, 5, 7 extra spaces and remove record with 3 spaces:
Code: [root@a10-52-143-28 ~]# mysql -u admin -p`cat /etc/psa/.psa.shadow` psa -e "select host, val, (length(val) - length(rtrim(val))) as extraspaces from dns_recs where host='ecz1.dev.sname.c002.aname.domain.com.' and val like 'ecz1%'" +---------------------------------------+-------------+-------------+ | host | val | extraspaces | +---------------------------------------+-------------+-------------+ | ecz1.dev.sname.c002.aname.domain.com. | ecz1 | 5 | | ecz1.dev.sname.c002.aname.domain.com. | ecz1 | 3 |

It's a feature of CSF, how to write a script that will output the contents of top -c to another file?
Problem is that the only way to stop this command is pressing CTRL + C, and i just need some option to specify how much time the tcpdump will be running, i need it running for 1 minute for example, and then it should automatically stop.
how do i get all the current dns values for a domain name? i have tried using 'dig domain any' and get varied results. the first time it is as if i ran 'dig domain a' I then run 'dig domain mx' and see the mx records. an issue of 'any' then shows the mx records so far i have to run dig with every record type. what is another way to get all the dns values for a domain name?
I use Munin to monitor the health of our servers, I can tell by looking at the graphs there's nothing to worry about, however, I'm struggling to baseline acceptable performance.what would be classed as 'normal' output for some of the more relevant munin graphs.
I've been looking at the Apache* modules and this is the output from one of our servers:
average of: 300 accesses per minute, 6 busy servers and 4.10MB a minute volume
max of: 1400 accesses per minute, 81 busy servers and 51MB a minute volume
This is a dedicated box running one site.
We have another box that is running approximately 30 sites
average of: 30 accesses per minute, 1 busy server and a 500K a minute volume
max of: 322 accesses per minute, 11 busy servers and a 4MB a minute volume.
These servers are pretty much the same spec, dual core 64Bit, 4GB of ram, two SATA disks in RAID1.
I am using Apache 2.4.1 (Win64), PHP 5.3.10 on Microsoft Windows 2008 server. I have also installed Microsoft VC++ 2010 (64 bit). I successfully configured mod_fcgid 2.3.7 as per the instructions. This was confirmed by running info php page. But when I run FastCGI test scripts, the output is displayed in text form and not in html format.
I have an apache server on windows which I wanted to speed up using caching systems.
I tried installing squid, and I got it working with a basic example config. It seemed to work well, however under more heavy load I experienced some weird behaviour where network output is 0 for several seconds at the time, and all clients just hang in the wind and wait for a respons.
Remote to the server is working fine, so it's definitely a squid issue.. with only apache running the server is constantly sending out data, no halts there.
for over a year now, with iptables. However recently, after upgrading to apache 2.2, the connections in netstat get listed as ipv6. A row can look like this for example:
As you can see, the remote ip address isn't complete, it's cut off, so the script used to sum up connections and insert into iptables isnt doing anything.
some software which would allow me to monitor critical information about my VPS and possibly give me graphs/charts that show me things like my system's load over time. Since it is a VPS I may want to see this charts/graphs via a web interface if I can't just download some rendered jpg's or somethin from the server on a regular basis.
So what I'm looking for is something kinda like the Bandwidth page under Web/FTP Stats in Cpanel so I can easily get a better idea over a few days or week(s) what times of the day my server is getting taxed and when load low.
anyone knows what's my best action here? unmount /home and fsck it? or shutdown the server and replace a drive? (but, from this error message, I couldn't guess which drive is it... also, the 3dm raid monitoring didn't find any problem, so maybe it's the controller?)
