Need help trouble shooting high CPU usage by PHP-fpm

- by user432506

There is a problem that is driving me crazy. After the day I tried to fix the CPU usage problem of my VPS, the CPU load has grown from 60% to 150%, and I have no idea what causes the problem. Please help me. I had installed a copy of mediawiki on a Linode 1024. The wiki is running on Niginx + PHP-fpm + MySql. The wiki doesn't have much traffic, only around 4000 requests/day, mostly from Google and Bing bots. It had been using around 60% (of total 400% on the Linode) of the CPU before. I thought it was a bit high, so two day ago, I was trying to fix the problem (not knowing what was waiting for me). I did nothing but added a new empty line to wiki's configure file, which would change the modified time of the configure file, and then all the cached page files would be set invalidated. I had done that before, and that would cause high CPU usage, but normally it would take only hours to let things back to normal again. Not this time, my CPU usage has been around 150% for more than two days. It is php-fpm using most of CPU reassures. Using 100% of three cores is not rare. I hadn't seen that before. There are other sites on the Linode, but it should be the wiki. Because if I offline the wiki, CPU usage will drop back to around 40% soon. The day I also duplicated php-fpm.conf, and opened it, but didn't changed it. I have no idea what I did wrong. I here ask for help to save myself from being crazy!!! It is php-fpm. Is there a way to find out what is it doing? I mean like which scripts are related and what function codes are running? top: top - 06:34:33 up 10 days, 4:23, 2 users, load average: 1.10, 1.24, 1.37 Tasks: 76 total, 4 running, 72 sleeping, 0 stopped, 0 zombie Cpu(s): 61.1%us, 3.1%sy, 0.0%ni, 32.8%id, 2.9%wa, 0.0%hi, 0.0%si, 0.1%st Mem: 1028684k total, 945192k used, 83492k free, 89580k buffers Swap: 524284k total, 18084k used, 506200k free, 530380k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 26721 www-data 20 0 208m 54m 34m R 99 5.4 0:09.07 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26592 www-data 20 0 207m 45m 26m R 91 4.5 0:12.77 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26706 www-data 20 0 196m 43m 34m S 47 4.3 0:15.19 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26583 www-data 20 0 197m 45m 35m S 33 4.5 0:19.08 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26787 www-data 20 0 206m 36m 18m R 25 3.7 0:00.41 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 26661 www-data 20 0 207m 46m 26m S 13 4.6 0:19.87 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 1971 mysql 20 0 155m 57m 3952 S 8 5.7 383:57.81 /usr/sbin/mysqld 242 root 20 0 0 0 0 S 1 0.0 0:51.36 [kworker/3:1] 5711 root 20 0 139m 95m 580 S 1 9.5 0:41.30 /usr/local/bin/memcached -d -u root -m 128 -p 11211 19463 root 20 0 190m 3984 1284 S 1 0.4 0:02.66 /opt/php5/sbin/php-fpm --fpm-config /opt/php5/etc/php-fpm.conf 29100 www-data 20 0 10928 5540 820 S 1 0.5 4:49.05 nginx: worker process vmstat 30 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 16912 81456 90784 554172 0 0 4 6 3 2 11 1 87 1 0 0 16912 78036 91000 555356 0 0 38 34 1397 375 12 1 87 0 4 0 16912 31776 91528 557508 0 0 78 42 3197 487 45 1 52 1 1 0 16912 83356 91768 558576 0 0 35 56 2608 449 32 1 67 1 1 0 16912 81548 92040 559720 0 0 41 31 1243 432 8 1 91 1 2 0 16912 53056 92332 562744 0 0 105 33 2013 581 17 1 81 1 2 0 16912 73236 92552 564844 0 0 68 36 1968 615 16 1 82 1 0 0 16912 91612 92904 566676 0 0 69 35 1845 692 13 1 85 1 1 0 16912 71248 93180 568428 0 0 58 33 1952 604 15 1 82 1 1 0 16868 55952 93516 572660 1 0 144 42 1801 637 12 1 86 1 2 0 16868 48324 94416 577844 0 0 189 66 2058 702 17 1 80 2 1 0 16928 58644 94592 578184 0 2 160 49 2578 723 25 1 70 3 5 0 16928 22600 94980 580568 0 0 89 32 1496 361 13 0 85 1 0 0 16988 49256 94500 576396 0 2 41 37 1601 426 14 1 85 0 5 0 18084 24336 86032 502748 0 37 83 68 2989 562 42 1 56 0 1 0 18084 123604 86376 506996 0 0 118 41 2201 573 22 1 76 1 2 0 18084 126984 86752 508876 0 0 64 53 1620 490 13 1 85 1 2 0 18084 103104 87148 510768 0 0 71 37 2757 602 33 1 64 1

Bind9 as a caching resolver fails with mismatch ID on localhost but not external IP

- by argibbs

I'm running Ubuntu 12.04 LTS on a machine on my private network. I have bind9 installed (v9.8.1-P1) via aptitude, so it appears to have put all the bits in the right places and the service starts automatically. I plan on adding some zones later, but first I'm just trying to get it working as a caching resolver. I installed bind, configured it, and starting using it. Initially I thought it was working ok, but then I found some sites weren't being resolved. I've pinned it down to being linked to the size of the result and bind failing-over to TCP mode. So: I'm trying to find out why bind is failing when I query for domain info and the result is 512 bytes (causing a truncation and retry on TCP). Specifically it fails with ID mismatches if I point dig at localhost, but works when I query the machine's own IP (192.168.0.2). This appears to be backwards to the problem that most people have when using bind (fails on external ip, works on localhost). If I do dig @localhost google.com (which has a response of <512 bytes) then it works; I get no warnings, and plenty of output. $ dig @localhost google.com ; <<>> DiG 9.8.1-P1 <<>> @localhost google.com [snip lots of output] ;; Query time: 39 msec ;; SERVER: 127.0.0.1#53(127.0.0.1) ;; WHEN: Thu Oct 17 23:08:34 2013 ;; MSG SIZE rcvd: 495 If I do dig @localhost play.google.com (which has a larger response) then I get back something like: $ dig @localhost play.google.com ;; Truncated, retrying in TCP mode. ;; ERROR: ID mismatch: expected ID 3696, got 27130 This seems to be standard, documented behaviour - when the UDP response is large (here 'large' == 512 bytes) it falls back to TCP. The ID mismatch is not expected though. If I do dig @192.168.0.2 play.google.com then I still get the warning about using TCP mode, but it otherwise works $ dig @192.168.0.2 play.google.com ;; Truncated, retrying in TCP mode. ; <<>> DiG 9.8.1-P1 <<>> @192.168.0.2 play.google.com [snip most of the output] ;; Query time: 5 msec ;; SERVER: 192.168.0.2#53(192.168.0.2) ;; WHEN: Thu Oct 17 23:05:55 2013 ;; MSG SIZE rcvd: 521 At the moment I've not set up any zones in my local instance, so it's just acting as a caching resolver. My options config is pretty much unchanged from standard, I've got the following set: options { directory "/var/cache/bind"; allow-query { 192.168/16; 127.0.0.1; }; forwarders { 8.8.8.8; 8.8.4.4; }; dnssec-validation auto; edns-udp-size 4096 ; allow-transfer { any; }; auth-nxdomain no; # conform to RFC1035 listen-on-v6 { any; }; }; And my /etc/resolv.conf is just nameserver 127.0.0.1 search .local The problem definitely seems linked to the failover to TCP mode: if I do dig +bufsize=4096 @localhost play.google.com then it works; no warning about failover to TCP, no ID mismatch, and a standard looking result. To be honest, if there was a way to force bind to use a much larger UDP buffer, that'd probably be good enough for me, but all I've been able to find mention of is max-udp-size 4096 and that doesn't change the behaviour in any way. I've also tried setting edns-udp-size 512 in case the problem is some weird EDNS issue with my router (which seems unlikely since the +bufsize=4096 flag works fine). I've also tried dig +trace @localhost play.google.com; this works. No truncation/TCP warning, and a full result. I've also tried changing the servers used in the forwarder (e.g. to OpenDNS), but that makes no difference. There's one last data point: if I repetitively do dig @localhost play.google.com I don't always get an ID mismatch, but sometimes a REFUSED error. I'm much more likely to get a REFUSED error if I dig the non-localhost IP (192.168.0.2) first: $ dig @localhost play.google.com ;; Truncated, retrying in TCP mode. ; <<>> DiG 9.8.1-P1 <<>> @localhost play.google.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 35104 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;play.google.com.

Email sent from server with rDNS & SPF being blocked by Hotmail

- by Canadaka

I have been unable to send email to users on hotmail or other Microsoft email servers for some time. Its been a major headache trying to find out why and how to fix the issue. The emails being sent that are blocked from my domain canadaka.net. I use Google Aps to host my regular email serverice for my @canadaka.net email addresses. I can sent email from my desktop or gmail to a hotmail without any problem. But any email sent from my server on behalf of canadaka.net is blocked, not even arriving in the junk email. The IP that the emails are being sent from is the same IP that my site is hosted on: 66.199.162.177 This IP is new to me since August 2010, I had a different IP for the previous 3-4 years. This IP is not on any credible spam lists http://www.anti-abuse.org/multi-rbl-check-results/?host=66.199.162.177 The one list spamcannibal.org my IP is listed on seems to be out of my control, says "no reverse DNS, MX host should have rDNS - RFC1912 2.1". But since I use Google for my email hosting, I don't have control over setting up RDNS for all the MX records. I do have Reverse DNS setup for my IP though, it resolves to "mail.canadaka.net". I have signed up for SNDS and was approved. My ip says "All of the specified IPs have normal status." Sender Score: 100 https://www.senderscore.org/lookup.php?lookup=66.199.162.177&ipLookup.x=55&ipLookup.y=14 My Mcafee threat level seems fine I have a TXT SPF record setup, I am currently using xname.org as my DNS, and they don't have a field for SPF, but their FAQ says to add the SPF info as a TXT entry. v=spf1 a include:_spf.google.com ~all Some "SPF checking" tools ive used detect that my domain has a valid SPF, but others don't. Like Microsoft's SPF wizard, i think this is because its specifically looking for an SPF record and not in the TXT. "No SPF Record Found. A and MX Records Available". From my home I can run "nslookup -type=TXT canadaka.net" and it returns: Server: google-public-dns-a.google.com Address: 8.8.8.8 Non-authoritative answer: canadaka.net text = "v=spf1 a include:_spf.google.com ~all" One strange thing I found is i'm unable to ping hotmail.com or msn.com or do a "telnet mail.hotmail.com 25". I am able to ping gmail.com and many other domains I tried. I tried changing my DNS servers to Google's Public DNS and did a ipconfig /flushdns but that had no effect. I am however able to connect with telnet to mx1.hotmail.com This is what the email headers look like when I send to a Google email server and I receive the email with no troubles. You can see that SPF is passing.

TXT (no records) I do have a TXT record, its been there for years, I did change it a week ago. Other sites that allow you to check your SPF detect it, but some others like Microsofts Wizard doesn't. This iw what my SPF record in my xname.org DNS file looks like: canadaka.net. 86400 IN TXT "v=spf1 a include:_spf.google.com ~all" I did have a nameserver as my 4th option that doens't have the TXT records since it doens't support it. So I removed it from the list and instead added wtfdns.com as my 4th adn 5th nameservers, which does support TXT.

Centos 6.3 vsftp unable to upload file to apache webserver

- by user148648

UnicodeEncodeError when uploading files in Django admin

- by Samuel Linde

Note: I asked this question on StackOverflow, but I realize this might be a more proper place to ask this kind of question. I'm trying to upload a file called 'Testaråäö.txt' via the Django admin app. I'm running Django 1.3.1 with Gunicorn 0.13.4 and Nginx 0.7.6.7 on a Debian 6 server. Database is PostgreSQL 8.4.9. Other Unicode data is saved to the database with no problem, so I guess the problem must be with the filesystem somehow. I've set http { charset utf-8; } in my nginx.conf. LC_ALL and LANG is set to 'sv_SE.UTF-8'. Running 'locale' verifies this. I even tried setting LC_ALL and LANG in my nginx init script just to make sure locale is set properly. Here's the traceback: Traceback (most recent call last): File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/handlers/base.py", line 111, in get_response response = callback(request, *callback_args, **callback_kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/options.py", line 307, in wrapper return self.admin_site.admin_view(view)(*args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 93, in _wrapped_view response = view_func(request, *args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/views/decorators/cache.py", line 79, in _wrapped_view_func response = view_func(request, *args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/sites.py", line 197, in inner return view(request, *args, **kwargs) File "/srv/django/letebo/app/cms/admin.py", line 81, in change_view return super(PageAdmin, self).change_view(request, obj_id) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 28, in _wrapper return bound_func(*args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 93, in _wrapped_view response = view_func(request, *args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/utils/decorators.py", line 24, in bound_func return func(self, *args2, **kwargs2) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/transaction.py", line 217, in inner res = func(*args, **kwargs) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/options.py", line 985, in change_view self.save_formset(request, form, formset, change=True) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/contrib/admin/options.py", line 677, in save_formset formset.save() File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/forms/models.py", line 482, in save return self.save_existing_objects(commit) + self.save_new_objects(commit) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/forms/models.py", line 613, in save_new_objects self.new_objects.append(self.save_new(form, commit=commit)) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/forms/models.py", line 717, in save_new obj.save() File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/base.py", line 460, in save self.save_base(using=using, force_insert=force_insert, force_update=force_update) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/base.py", line 504, in save_base self.save_base(cls=parent, origin=org, using=using) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/base.py", line 543, in save_base for f in meta.local_fields if not isinstance(f, AutoField)] File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/fields/files.py", line 255, in pre_save file.save(file.name, file, save=False) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/db/models/fields/files.py", line 92, in save self.name = self.storage.save(name, content) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/files/storage.py", line 48, in save name = self.get_available_name(name) File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/files/storage.py", line 74, in get_available_name while self.exists(name): File "/srv/.virtualenvs/letebo/lib/python2.6/site-packages/django/core/files/storage.py", line 218, in exists return os.path.exists(self.path(name)) File "/srv/.virtualenvs/letebo/lib/python2.6/genericpath.py", line 18, in exists st = os.stat(path) UnicodeEncodeError: 'ascii' codec can't encode characters in position 52-54: ordinal not in range(128) I tried running Gunicorn with debugging turned on, and the file uploads without any problem at all. I suppose this must mean that the issue is with Nginx. Still beats me where to look, though. Here are the raw response headers from Gunicorn and Nginx, if it makes any sense: Gunicorn: HTTP/1.1 302 FOUND Server: gunicorn/0.13.4 Date: Thu, 09 Feb 2012 14:50:27 GMT Connection: close Transfer-Encoding: chunked Expires: Thu, 09 Feb 2012 14:50:27 GMT Vary: Cookie Last-Modified: Thu, 09 Feb 2012 14:50:27 GMT Location: http://my-server.se:8000/admin/cms/page/15/ Cache-Control: max-age=0 Content-Type: text/html; charset=utf-8 Set-Cookie: messages="yada yada yada"; Path=/ Nginx: HTTP/1.1 500 INTERNAL SERVER ERROR Server: nginx/0.7.67 Date: Thu, 09 Feb 2012 14:50:57 GMT Content-Type: text/html; charset=utf-8 Transfer-Encoding: chunked Connection: close Vary: Cookie 500 UPDATE: Both locale.getpreferredencoding() and sys.getfilesystemencoding() outputs 'UTF-8'. locale.getdefaultlocale() outputs ('sv_SE', 'UTF8'). This seem correct to me, so I'm still not sure why I keep getting these errors.

Macports irssi & perl5 installation issues

Long time reader, first time poster. Big, appreciative thanks for everyone's collective questioning and answering here and at stackoverflow, it's helped me quite a lot over the time I've been learning answers through these sites! Apologies in advance if I didn't search hard enough on posts already up on this site to find out what I could do about this issue, but I thought I'd just reach out for the sake of trying at least once.

I'm not really a perl user beyond enjoying it for massive directory-recursive find/replace operations within text files, so I haven't much of an idea what the permissions here are supposed to look like, and I'm not really sure how to go about determining how macports has gone and installed perl this way when it's otherwise worked without failure for years now. Does anyone have any recommendations for the sanest path towards rectifying this issue? Also, is there any interesting reason as to why the macports default for the perl5 port installs 5.12.4, and not 5.16.0, which has to be explicitly installed via the perl5.16 port? Thanks again!

Getting HAPROXY to redirect http to https in users browser session

- by Jon

We are currently using a Internet cloud provider to host our SaaS platform. The platform consists of a Firewall - Cloud Provider SLB - - Apache Web Server - HAPROXY SLB - Liferay Platform We have had to use HAPROXY because of an issue with the cloud providers SLB that meant we were unable to use it for load balancing the Liferay platform applications. I have implemented HAPROXY in our secure tier and that seems to do the trick of load balancing the requests quite adequately. However during testing we encountered a functional issue whereby selecting a sub-menu from the web portal resulted in the application hanging, using an http analyser we saw that the request being passed back to the users browser was in http, from discussing this with the software vendor it transpires that the Liferay application has some hard-coded http links, and that other customers have worked around this by using physical NLB's such as F5 and redirecting the http traffic to https. The entry in the HAPROXY logs reads: haproxy[2717]: haproxy[2717]: <Apache Web Agent>:37957 [11/Apr/2013:08:07:00.128] http-uapi uapi/<ServerName> 0/0/0/9/10 200 4912 - - ---- 4/2/1/2/0 0/0 "GET /servicedesk/controller?docommand=renderradform&!key=esd_sfb001_frm_feedback_forms_list&isportalintegratedmode=true&USR=joe.bloggs%40gmail.com&_dc=1365667773097&redirecturl=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&sso_token=ALiYv2UqzLsAhSw1ZchRDlCHlq44Bhj9&ONERROR=%2Fweb%2Fjsp%2Fapps%2Fportal-integration-error.jsp&itype=login&slicetoken=NW51O%242aRo%2C_Zz%2476P_9DTtnFmz6%28bhk&AUTOFORWARDURL=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&LOGINPAGE=https%3A%2F%2F<FQDN of Web Portal>%2Fweb%2F4732cf01-82c3-4bc5-b6c9-552253e672cf%2Fworkflow-tools&appid=1&!uid=1&!redownloadToken=7.0.3.1.1363611301.0&userlocale=en_US&!datechanged=2012-05-18%2015:05:31.38 HTTP/1.1" :37957 [11/Apr/2013:08:07:00.128] http-uapi uapi/<ServerName> 0/0/0/9/10 200 4912 - - ---- 4/2/1/2/0 0/0 "GET /servicedesk/controller?docommand=renderradform&!key=esd_sfb001_frm_feedback_forms_list&isportalintegratedmode=true&USR=joe.bloggs%40gmail.com&_dc=1365667773097&redirecturl=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&sso_token=ALiYv2UqzLsAhSw1ZchRDlCHlq44Bhj9&ONERROR=%2Fweb%2Fjsp%2Fapps%2Fportal-integration-error.jsp&itype=login&slicetoken=NW51O%242aRo%2C_Zz%2476P_9DTtnFmz6%28bhk&AUTOFORWARDURL=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_SFB001_FRM_FEEDBACK_FORMS_LIST%26isportalintegratedmode%3Dtrue&LOGINPAGE=https%3A%2F%2F<FQDN of Web Portal>%2Fweb%2F4732cf01-82c3-4bc5-b6c9-552253e672cf%2Fworkflow-tools&appid=1&!uid=1&!redownloadToken=7.0.3.1.1363611301.0&userlocale=en_US&!datechanged=2012-05-18%2015:05:31.38 HTTP/1.1" The corresponding HTTP browser entry shows: http://<FQDN of ServiceDesk>/servicedesk/controller?docommand=renderradform&!key=esd_org019_frm_contact_list&isportalintegratedmode=true&USR=joe.bloggs%40gmail.com&_dc=1365665987887&redirecturl=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_ORG019_FRM_CONTACT_LIST%26isportalintegratedmode%3Dtrue&sso_token=3NxsXYORMPp32SwL8ftVUCMH2QdWLH82&ONERROR=%2Fweb%2Fjsp%2Fapps%2Fportal-integration-error.jsp&itype=login&slicetoken=NW51O%242aRo%2C_Zz%2476P_9DTtnFmz6%28bhk&AUTOFORWARDURL=controller%3Fdocommand%3Drenderbody%26%21key%3DESD_ORG019_FRM_CONTACT_LIST%26isportalintegratedmode%3Dtrue&LOGINPAGE=https%3A%2F%2F<FQDN of Web Portal>>%2Fweb%2F4732cf01-82c3-4bc5-b6c9-552253e672cf%2Fapplication-setup&appid=1&!uid=1&!redownloadToken=7.0.3.1.1363611301.0&userlocale=en_US&!datechanged=2012-10-26%2019:00:25.08 From reading through the forums and other sites it looks like we should be use to use HAPROXY to redirect the traffic to https, but try as I might I cant get it to work.

Two network interfaces and two IP addresses on the same subnet in Linux

- by Scott Duckworth

I recently ran into a situation where I needed two IP addresses on the same subnet assigned to one Linux host so that we could run two SSL/TLS sites. My first approach was to use IP aliasing, e.g. using eth0:0, eth0:1, etc, but our network admins have some fairly strict settings in place for security that squashed this idea: They use DHCP snooping and normally don't allow static IP addresses. Static addressing is accomplished by using static DHCP entries, so the same MAC address always gets the same IP assignment. This feature can be disabled per switchport if you ask and you have a reason for it (thankfully I have a good relationship with the network guys and this isn't hard to do). With the DHCP snooping disabled on the switchport, they had to put in a rule on the switch that said MAC address X is allowed to have IP address Y. Unfortunately this had the side effect of also saying that MAC address X is ONLY allowed to have IP address Y. IP aliasing required that MAC address X was assigned two IP addresses, so this didn't work. There may have been a way around these issues on the switch configuration, but in an attempt to preserve good relations with the network admins I tried to find another way. Having two network interfaces seemed like the next logical step. Thankfully this Linux system is a virtual machine, so I was able to easily add a second network interface (without rebooting, I might add - pretty cool). A few keystrokes later I had two network interfaces up and running and both pulled IP addresses from DHCP. But then the problem came in: the network admins could see (on the switch) the ARP entry for both interfaces, but only the first network interface that I brought up would respond to pings or any sort of TCP or UDP traffic. After lots of digging and poking, here's what I came up with. It seems to work, but it also seems to be a lot of work for something that seems like it should be simple. Any alternate ideas out there? Step 1: Enable ARP filtering on all interfaces: # sysctl -w net.ipv4.conf.all.arp_filter=1 # echo "net.ipv4.conf.all.arp_filter = 1" >> /etc/sysctl.conf From the file networking/ip-sysctl.txt in the Linux kernel docs: arp_filter - BOOLEAN 1 - Allows you to have multiple network interfaces on the same subnet, and have the ARPs for each interface be answered based on whether or not the kernel would route a packet from the ARP'd IP out that interface (therefore you must use source based routing for this to work). In other words it allows control of which cards (usually 1) will respond to an arp request. 0 - (default) The kernel can respond to arp requests with addresses from other interfaces. This may seem wrong but it usually makes sense, because it increases the chance of successful communication. IP addresses are owned by the complete host on Linux, not by particular interfaces. Only for more complex setups like load- balancing, does this behaviour cause problems. arp_filter for the interface will be enabled if at least one of conf/{all,interface}/arp_filter is set to TRUE, it will be disabled otherwise Step 2: Implement source-based routing I basically just followed directions from http://lartc.org/howto/lartc.rpdb.multiple-links.html, although that page was written with a different goal in mind (dealing with two ISPs). Assume that the subnet is 10.0.0.0/24, the gateway is 10.0.0.1, the IP address for eth0 is 10.0.0.100, and the IP address for eth1 is 10.0.0.101. Define two new routing tables named eth0 and eth1 in /etc/iproute2/rt_tables: ... top of file omitted ... 1 eth0 2 eth1 Define the routes for these two tables: # ip route add default via 10.0.0.1 table eth0 # ip route add default via 10.0.0.1 table eth1 # ip route add 10.0.0.0/24 dev eth0 src 10.0.0.100 table eth0 # ip route add 10.0.0.0/24 dev eth1 src 10.0.0.101 table eth1 Define the rules for when to use the new routing tables: # ip rule add from 10.0.0.100 table eth0 # ip rule add from 10.0.0.101 table eth1 The main routing table was already taken care of by DHCP (and it's not even clear that its strictly necessary in this case), but it basically equates to this: # ip route add default via 10.0.0.1 dev eth0 # ip route add 130.127.48.0/23 dev eth0 src 10.0.0.100 # ip route add 130.127.48.0/23 dev eth1 src 10.0.0.101 And voila! Everything seems to work just fine. Sending pings to both IP addresses works fine. Sending pings from this system to other systems and forcing the ping to use a specific interface works fine (ping -I eth0 10.0.0.1, ping -I eth1 10.0.0.1). And most importantly, all TCP and UDP traffic to/from either IP address works as expected. So again, my question is: is there a better way to do this? This seems like a lot of work for a seemingly simple problem.

Unusually high memory usage on a CentOS VPS with 512 guaranteed RAM

- by Andrei Bârsan

I'm working on a medium-sized web application written in PHP that's running on a VPS with 512mb ram. The webapp hasn't been officially launched yet, so there isn't too much traffic going on, just me and a few other people working on it. There is another slightly smaller webapp also hosted on this machine, among 4-5 other small static sites. We are running Centos 5 32-bit & cPanel/WHM. This is the result of running ps aux and, as you can see, it's not using 100% of the RAM. However, on the hypanel overview, it's always shown as using aroun 500MB ram, just for running apache, mysql, and the lowest-memory-footprint versions of the mail server, ftp server etc. -bash-3.2# ps aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 2156 664 ?

Do you have any idea if this is normal and more resources should be acquired? I don't think... since there isn't too much data or traffic online yet.

Bypass cache for mobile user agents, VARNISH+NGINX+W3CACHE

Right now I'm running Wordpress w/ W3 Cache on nginx with varnish front end. I'm trying to use the WP Touch Pro plugin for wordpress to display mobile sites, but it is not working.

In Exim, is RBL spam rejected prior to being scanned by SpamAssassin?

- by user955664

I've recently been battling spam issues on our mail server. One account in particular was getting hammered with incoming spam. SpamAssassin's memory use is one of our concerns. What I've done is enable RBLs in Exim. I now see many rejection notices in the Exim log based on the various RBLs, which is good. However, when I run Eximstats, the numbers seem to be the same as they were prior to the enabling of the RBLs. I am assuming because the email is still logged in some way prior to the rejection. Is that what's happening, or am I missing something else? Does anyone know if these emails are rejected prior to being processed by SpamAssassin? Or does anyone know how I'd be able to find out? Is there a standard way to generate SpamAssassin stats, similar to Eximstats, so that I could compare the numbers? Thank you for your time and any advice. Edit: Here is the ACL section of my Exim configuration file ###################################################################### # ACLs # ###################################################################### begin acl # ACL that is used after the RCPT command check_recipient: # to block certain wellknown exploits, Deny for local domains if # local parts begin with a dot or contain @ % ! / | deny domains = +local_domains local_parts = ^[.] : ^.*[@%!/|] # to restrict port 587 to authenticated users only # see also daemon_smtp_ports above accept hosts = +auth_relay_hosts condition = ${if eq {$interface_port}{587} {yes}{no}} endpass message = relay not permitted, authentication required authenticated = * # allow local users to send outgoing messages using slashes # and vertical bars in their local parts. # Block outgoing local parts that begin with a dot, slash, or vertical # bar but allows them within the local part. # The sequence \..\ is barred.

Packets marked by iptables only sent to the correct routing table sometimes

I do not know why the first packet goes through the correct routing table, and the second doesn't. Both are marked. Once again, I do not want ALL packets system-wide to go through the VPN, I only want packets from a specific user (UID=999) to go through the VPN. I am testing ipchicken.com and walmart.com via links, from the same user, same shell. walmart.com appears to use the VPN; ipchicken.com does not. Any help appreciated. Will send 0.5 bitcoins to answerer who makes this fixed.

Windows 7 cannot join samba domain

- by Antonis Christofides

I have a 3.5.6 samba server with a LDAP backend (both on Debian 6.0). I've been successfully adding Windows XP machines to the domain for years. I now try to add Windows 7. I have made the recommended registry changes, but I don't have any success so far. Here is what happens: 1. I go to computer name, select "Domain" instead of "Workgroup", type in the domain name, click OK. It asks me for the username and password of an account that can add computers to the domain; I enter them. After about 40 seconds, I get the following message: The following error occurred attempting to join the domain "ITIA": The specified computer account could not be found. Contact an administrator to verify the account is in the domain. If the account has been deleted unjoin, reboot, and rejoin the domain. Despite this, the samba server successfully creates the computer account. 2. Therefore, if I try again a second time, without deleting the already created computer account, I get a different error: The following error occurred attempting to join the domain "ITIA": The specified account already exists. (Note that until a while ago samba wasn't configured to automatically create computer accounts. What I did whenever I wanted an XP to join was to manually create it. When I first attempted to solve the Windows 7 join problem, I setup samba to do this automatically, as this is what most people do, as I understand, and I thought that it might be related. I haven't attempted to add an XP since I made this change, so I don't know if it works, but whether it works or not, the problem remains.) Update 1: Here are the relevant parts of smb.conf: [global] panic action = /usr/share/samba/panic-action %d workgroup = ITIA server string = Itia file server announce as = NT interfaces = 147.102.160.1 volume = %h passdb backend = ldapsam:ldap://ldap.itia.ntua.gr:389 ldap admin dn = uid=samba,ou=daemons,dc=itia,dc=ntua,dc=gr ldap ssl = off ldap suffix = dc=itia,dc=ntua,dc=gr ldap user suffix = ou=people ldap group suffix = ou=groups ldap machine suffix = ou=computers unix password sync = no add machine script = smbldap-useradd -w -i %u log file = /var/log/samba/samba-log.all log level = 3 max log size = 5000 syslog = 2 socket options = SO_KEEPALIVE TCP_NODELAY encrypt passwords = true password level = 1 security = user domain master = yes local master = no wins support = yes domain logons = yes idmap gid = 1000-2000 Update 2: The server has a single network interface eth1 (also an unused eth0 that shows up only in the kernel boot messages) and two ip addresses; the main, 147.102.160.1, and an additional one, 147.102.160.37, that comes up with "ip addr add 147.102.160.37/32 dev eth1" (used only for a web site that has a different certificate than other web sites served from the same machine). One of the problems I recently faced was that samba was using the latter IP address. I fixed that by adding the "interfaces = 147.102.160.1" statement in smb.conf. Now: acheloos:/etc/apache2# tcpdump host 147.102.160.40 and not port 5900 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes 13:13:56.549048 IP lithaios.itia.civil.ntua.gr.netbios-dgm > 147.102.160.255.netbios-dgm: NBT UDP PACKET(138) 13:13:56.549056 ARP, Request who-has acheloos2.itia.civil.ntua.gr tell lithaios.itia.civil.ntua.gr, length 46 13:13:56.549091 ARP, Reply acheloos2.itia.civil.ntua.gr is-at 00:10:4b:b4:9e:59 (oui Unknown), length 28 13:13:56.549324 IP acheloos.itia.civil.ntua.gr.netbios-dgm > lithaios.itia.civil.ntua.gr.netbios-dgm: NBT UDP PACKET(138) 13:13:56.549608 IP lithaios.itia.civil.ntua.gr.netbios-dgm > acheloos2.itia.civil.ntua.gr.netbios-dgm: NBT UDP PACKET(138) 13:13:56.549741 IP acheloos.itia.civil.ntua.gr.netbios-dgm > lithaios.itia.civil.ntua.gr.netbios-dgm: NBT UDP PACKET(138) 13:13:56.550364 IP lithaios.itia.civil.ntua.gr.netbios-dgm > acheloos.itia.civil.ntua.gr.netbios-dgm: NBT UDP PACKET(138) 13:13:56.550468 IP acheloos.itia.civil.ntua.gr.netbios-dgm > lithaios.itia.civil.ntua.gr.netbios-dgm: NBT UDP PACKET(138) (acheloos2 is the second IP address, 147.102.160.37). The above dump occurs when I click "OK" (to join the domain), until it asks me for the username and password of a user that can join the domain. I don't know why the client is contacting the second IP address. I tried temporarily deactivating it, but I still had some related ARP traffic (though I think not IP traffic).

local user cannot access vsftpd server

- by Zloy Smiertniy

I'm currently running a vsftpd server and I added the necessary configurations in vsftpd.conf so that local users can use clients like FileZilla to manage their homes in a server. I found out that only users in the sudoers list access without a problem only they can't download the files, but users that are not sudoers cannot even access their homes from a client but they can access by a web browser using the FTP protocol and they can only access their home directories (as intented) Im running a fedora 14 on my server and my vsftpd.conf looks like this: # Example config file /etc/vsftpd/vsftpd.conf # # The default compiled in settings are fairly paranoid.

nginx returning authentication in IE

- by James MacLeod

I am having a few issues with an nginx server. I have a site setup that keeps requesting authentication when accessed from IE but in firefox and safari the site is fine no request for authentication. Reading around the web I can see that it could be the gzip that may be causing errors, but the other sites are working without issue. Here is the config: user sysadmin sysadmin; worker_processes 8; error_log logs/error.log debug; events { worker_connections 1024; } http { passenger_root /usr/lib/ruby/gems/1.8/gems/passenger-2.2.9; passenger_ruby /usr/bin/ruby1.8; include mime.types; default_type application/octet-stream; client_header_timeout 3m; client_body_timeout 3m; client_max_body_size 5m; send_timeout 3m; client_header_buffer_size 1k; large_client_header_buffers 4 4k; gzip on; gzip_min_length 1100; gzip_buffers 4 8k; gzip_types text/plain; output_buffers 1 32k; postpone_output 1460; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 75 20; server { listen 80; server_name .reg-power.com .reg-power.co.uk .reg-power.eu .reg-power.eu.com .reg-power.net .reg-power.org .reg-power.org.uk .reg-power.uk.com .regegen.eu .regpower.co.uk .regpower.eu .regpower.eu.com .regpower.net .regpower.org .regpower.org.uk .regpower.uk.com .renegen.com .renegen.eu .renewableenergygeneration.co.uk .renewableenergygeneration.com reg.rails1.flowhost.co.uk; root /home/sysadmin/reg/current/public; passenger_enabled on; rails_env production; index index.html; } server { listen 80; server_name media.reg-power.com; root /home/sysadmin/admin/current/public; index index.html; } server { listen 80; server_name admin.reg-power.com admin.rails1.flowhost.co.uk; root /home/sysadmin/admin/current/public; passenger_enabled on; rails_env production; index index.html; } server { listen 80; server_name .livingfuels.co.uk livingfuels.rails1.flowhost.co.uk; root /home/sysadmin/livingfuels/current/public; passenger_enabled on; rails_env production; index index.html; } server { listen 80; server_name .regbiopower.com .regbiopower.co.uk regbiopower.rails1.flowhost.co.uk; root /home/sysadmin/regbiopower/current/public; passenger_enabled on; rails_env production; index index.html; } server { listen 80; server_name .clpwindprojects.co.uk clp.rails1.flowhost.co.uk; access_log /home/sysadmin/clp/logs/access.log; location / { root /home/sysadmin/clp; index index.php; if (-f $request_filename) { expires 30d; break; } if (!-e $request_filename) { rewrite ^(.+)$ /index.php?q=$1 last; } } location ~ .php$ { fastcgi_pass 127.0.0.1:49232; #this must point to the socket spawn_fcgi is running on. fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /home/sysadmin/clp$fastcgi_script_name; # same path as above fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT /home/sysadmin/clp; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; } } } As you can see there is no reference to a http authentication

firefox, opera 'The connection was reset' on few POST method calls on Windows and Ubuntu

- by Gopalakrishnan Subramani

my website works well with GET method, also few POST methods. Some pages with POST method doesn't work. Some pages with POST work. For example, login page uses POST that works fine. When I post the data on webpage, firefox says "Connecting..." and finally report connection timed out error. The same behavior happens with Opera as well. However Google Chrome works fine. At the server side, I use nginx 1.2.4 with HTTPS and uwsgi for python (flask framework) app. I use geotrust certificate. The same behavior happens with Windows 7 and Ubuntu 12.04 on firefox. I tried firefox in safemode, but no luck. Set auto-detect proxy settings. no luck. Cleared all cookies. no luck Anyone help me to fix this issue? I am posting ngix config. shame on me. I use root, I know which is not advised. need to fix soon. user root; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; # server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "msie6"; # gzip_vary on; # gzip_proxied any; # gzip_comp_level 6; # gzip_buffers 16 8k; # gzip_http_version 1.1; # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; ## # nginx-naxsi config ## # Uncomment it if you installed nginx-naxsi ## #include /etc/nginx/naxsi_core.rules; ## # nginx-passenger config ## # Uncomment it if you installed nginx-passenger ## #passenger_root /usr; #passenger_ruby /usr/bin/ruby; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; ssl_session_cache shared:SSL:10m; ssl_session_timeout 10m; server { listen 80; server_name www.example.com; rewrite ^(.*) https://example.com$1 permanent; } server { listen 80; server_name example.com; rewrite ^ https://$server_name$request_uri? permanent; } server { listen 443; server_name example.com; keepalive_timeout 70; ssl on; ssl_certificate /root/cc.cert; ssl_certificate_key /root/cc.key; ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2; #ssl_ciphers HIGH:!aNULL:!MD5; ssl_ciphers RC4:HIGH:!aNULL:!MD5; ssl_prefer_server_ciphers on; location / { try_files $uri @app; } location @app { include uwsgi_params; uwsgi_pass unix:/tmp/uwsgi.sock; } } } #mail { # # See sample authentication script at: # # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript # # # auth_http localhost/auth.php; # # pop3_capabilities "TOP" "USER"; # # imap_capabilities "IMAP4rev1" "UIDPLUS"; # # server { # listen localhost:110; # protocol pop3; # proxy on; # } # # server { # listen localhost:143; # protocol imap; # proxy on; # } #}

curl can't verify cert using capath, but can with cacert option

- by phylae

I am trying to use curl to connect to a site using HTTPS. But curl is failing to verify the SSL cert. $ curl --verbose --capath ./certs/ --head https://example.com/ * About to connect() to example.com port 443 (#0) * Trying 1.1.1.1... connected * Connected to example.com (1.1.1.1) port 443 (#0) * successfully set certificate verify locations: * CAfile: none CApath: ./certs/ * SSLv3, TLS handshake, Client hello (1): * SSLv3, TLS handshake, Server hello (2): * SSLv3, TLS handshake, CERT (11): * SSLv3, TLS alert, Server hello (2): * SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed * Closing connection #0 curl: (60) SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed More details here: http://curl.haxx.se/docs/sslcerts.html curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option. I know about the -k option. But I do actually want to verify the cert. The certs directory has been properly hashed with c_rehash . and it contains: A Verisign intermediate cert Two self-signed certs The above site should be verified with the Verisign intermediate cert. When I use the --cacert option instead (and point directly to the Verisign cert) curl is able to verify the SSL cert. $ curl --verbose --cacert ./certs/verisign-intermediate-ca.crt --head https://example.com/ * About to connect() to example.com port 443 (#0) * Trying 1.1.1.1... connected * Connected to example.com (1.1.1.1) port 443 (#0) * successfully set certificate verify locations: * CAfile: ./certs/verisign-intermediate-ca.crt CApath: /etc/ssl/certs * SSLv3, TLS handshake, Client hello (1): * SSLv3, TLS handshake, Server hello (2): * SSLv3, TLS handshake, CERT (11): * SSLv3, TLS handshake, Server finished (14): * SSLv3, TLS handshake, Client key exchange (16): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSL connection using RC4-SHA * Server certificate: * subject: C=US; ST=State; L=City; O=Company; OU=ou1; CN=example.com * start date: 2011-04-17 00:00:00 GMT * expire date: 2012-04-15 23:59:59 GMT * common name: example.com (matched) * issuer: C=US; O=VeriSign, Inc.; OU=VeriSign Trust Network; OU=Terms of use at https://www.verisign.com/rpa (c)10; CN=VeriSign Class 3 Secure Server CA - G3 * SSL certificate verify ok. > HEAD / HTTP/1.1 > User-Agent: curl/7.19.7 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15 > Host: example.com > Accept: */* > < HTTP/1.1 404 Not Found HTTP/1.1 404 Not Found < Cache-Control: must-revalidate,no-cache,no-store Cache-Control: must-revalidate,no-cache,no-store < Content-Type: text/html;charset=ISO-8859-1 Content-Type: text/html;charset=ISO-8859-1 < Content-Length: 1267 Content-Length: 1267 < Server: Jetty(7.2.2.v20101205) Server: Jetty(7.2.2.v20101205) < * Connection #0 to host example.com left intact * Closing connection #0 * SSLv3, TLS alert, Client hello (1): In addition, if I try hitting one of the sites using a self signed cert and the --capath option, it also works. (Let me know if I should post an example of that.) This implies that curl is finding the cert directory, and it is properly hash. Finally, I am able to verify the SSL cert with openssl, using its -CApath option. $ openssl s_client -CApath ./certs/ -connect example.com:443 CONNECTED(00000003) depth=3 /C=US/O=VeriSign, Inc./OU=Class 3 Public Primary Certification Authority verify return:1 depth=2 /C=US/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=(c) 2006 VeriSign, Inc. - For authorized use only/CN=VeriSign Class 3 Public Primary Certification Authority - G5 verify return:1 depth=1 /C=US/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=Terms of use at https://www.verisign.com/rpa (c)10/CN=VeriSign Class 3 Secure Server CA - G3 verify return:1 depth=0 /C=US/ST=State/L=City/O=Company/OU=ou1/CN=example.com verify return:1 --- Certificate chain 0 s:/C=US/ST=State/L=City/O=Company/OU=ou1/CN=example.com i:/C=US/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=Terms of use at https://www.verisign.com/rpa (c)10/CN=VeriSign Class 3 Secure Server CA - G3 --- Server certificate -----BEGIN CERTIFICATE----- <cert removed> -----END CERTIFICATE----- subject=/C=US/ST=State/L=City/O=Company/OU=ou1/CN=example.com issuer=/C=US/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=Terms of use at https://www.verisign.com/rpa (c)10/CN=VeriSign Class 3 Secure Server CA - G3 --- No client certificate CA names sent --- SSL handshake has read 1563 bytes and written 435 bytes --- New, TLSv1/SSLv3, Cipher is RC4-SHA Server public key is 2048 bit Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : RC4-SHA Session-ID: D65C4C6D52E183BF1E7543DA6D6A74EDD7D6E98EB7BD4D48450885188B127717 Session-ID-ctx: Master-Key: 253D4A3477FDED5FD1353D16C1F65CFCBFD78276B6DA1A078F19A51E9F79F7DAB4C7C98E5B8F308FC89C777519C887E2 Key-Arg : None Start Time: 1303258052 Timeout : 300 (sec) Verify return code: 0 (ok) --- QUIT DONE How can I get curl to verify this cert using the --capath option?

Nginx & Apache Cannot get try_files to work with permalinks

- by tcherokee

I have been working on this for the past two weeks not and for some reason I cannot seem to get nginx's try_files to work with my wordpress permalinks. I am hoping someone will be able to tell me where I am going wrong and also hopefully tell me if I made any major errors with my configurations as well (I am an nginx newbie... but learning :) ). Here are my Configuration files nginx.conf user www-data; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; # server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## # Defines the cache log format, cache log location # and the main access log location. log_format cache '***$time_local ' '$upstream_cache_status ' 'Cache-Control: $upstream_http_cache_control ' 'Expires: $upstream_http_expires ' '$host ' '"$request" ($status) ' '"$http_user_agent" ' ; access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } mydomain.com.conf server { listen 123.456.78.901:80; # IP goes here. server_name www.mydomain.com mydomain.com; #root /var/www/mydomain.com/prod; index index.php; ## mydomain.com -> www.mydomain.com (301 - Permanent) if ($host !~* ^(www|dev)) { rewrite ^/(.*)$ $scheme://www.$host/$1 permanent; } # Add trailing slash to */wp-admin requests. rewrite /wp-admin$ $scheme://$host$uri/ permanent; # All media (including uploaded) is under wp-content/ so # instead of caching the response from apache, we're just # going to use nginx to serve directly from there. location ~* ^/(wp-content|wp-includes)/(.*)\.(jpg|png|gif|jpeg|css|js|m$ root /var/www/mydomain.com/prod; } # Don't cache these pages. location ~* ^/(wp-admin|wp-login.php) { proxy_pass http://backend; } location / { if ($http_cookie ~* "wordpress_logged_in_[^=]*=([^%]+)%7C") { set $do_not_cache 1; } proxy_cache_key "$scheme://$host$request_uri $do_not_cache"; proxy_cache main; proxy_pass http://backend; proxy_cache_valid 30m; # 200, 301 and 302 will be cached. # Fallback to stale cache on certain errors. # 503 is deliberately missing, if we're down for maintenance # we want the page to display. #try_files $uri $uri/ /index.php?q=$uri$args; #try_files $uri =404; proxy_cache_use_stale error timeout invalid_header http_500 http_502 http_504 http_404; } # Cache purge URL - works in tandem with WP plugin. # location ~ /purge(/.*) { # proxy_cache_purge main "$scheme://$host$1"; # } # No access to .htaccess files. location ~ /\.ht { deny all; } } # End server gzip.conf # Gzip Configuration. gzip on; gzip_disable msie6; gzip_static on; gzip_comp_level 4; gzip_proxied any; gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript; proxy.conf # Set proxy headers for the passthrough proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_max_temp_file_size 0; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; add_header X-Cache-Status $upstream_cache_status; backend.conf upstream backend { # Defines backends. # Extracting here makes it easier to load balance # in the future.

Server HTTP Load times slow?

- by cdog5000

Hello, My server @ codemeh.com (HTTP Server) seems to be randomly loading slowly, I cannot tell if it just my forums (http://www.codemeh.com/forums/) that are loading slowly or if the WHOLE site is just loading slowly since my forums are the largest thing on the site right now. load average: 0.02, 0.17, 0.20 That is super low to my knowledge. I have tried Google Page Analytic plug-in for FireFox to solve the problem but nothing comes up that is VERY bad. If someone could investigate this for me since I am very new at apache and server configurations. Thanks!

I've posted this yesterday on asp forum but no one replied so perhaps I'll have better luck here. For some reason the OnUpdating method does not pull new values from the grid which is in edit mode. I've search and have come across several blogs and sites, some sugesting that an ObjectDataSource is required in order to use the "e.NewValue" construct others provide code to the contrary. I don't get any errors - the variables in the code file would contain the old values rather then new ones. I don't want to use the ODS way of manipulating the data. My delete method works but not the update one. Can you suggest what is wrong with the code? Here is what I've got: aspx file: <asp:GridView ID="gvBlack" runat="server" AutoGenerateColumns="False" OnRowUpdating="gvBlack_OnUpdating" OnRowEditing="gvBlack_RowEditing"> <Columns> <%--<asp:BoundField DataField="Ident_Black" ReadOnly="True" visible="false" />--%> <asp:TemplateField ItemStyle-Width="1px"> <EditItemTemplate> <asp:Label ID="lblIdent_Black" runat="server" Text='<%# Bind("Ident_Black") %>' Visible="false" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Model" > <ItemTemplate> <asp:Label ID="lblModel_Black" runat="server" Text='<%# Bind("Model_Black") %>' width="130px" /> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtModel_Black" runat="server" Text='<%# Eval("Model_Black") %>' width="100px" /> <asp:RequiredFieldValidator ID="rfvModel_Black" runat="server" ControlToValidate="txtModel_Black" SetFocusOnError="true" ErrorMessage="*" ValidationGroup="CurrentMfg" ForeColor="Red" Font-Bold="true" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Description" > <ItemTemplate> <asp:Label ID="lblDesc_Black" runat="server" Text='<%# Bind("Desc_Black") %>' width="200px" /> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtDesc_Black" runat="server" Text='<%# Eval("Desc_Black") %>' width="170px" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Qty" > <ItemTemplate> <asp:Label ID="lblQty_Black" runat="server" Text='<%# Bind("Qty_Black") %>' width="35px" /> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtQty_Black" runat="server" Text='<%# Eval("Qty_Black") %>' width="35px" /> <asp:RequiredFieldValidator ID="rfvQty_Black" runat="server" ControlToValidate="txtQty_Black" SetFocusOnError="true" ErrorMessage="*" ValidationGroup="CurrentMfg" ForeColor="Red" Font-Bold="true" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Reorder Limit"> <ItemTemplate> <asp:Label ID="lblBlack_Reorder_Limit" runat="server" Text='<%# Bind("Black_Reorder_Limit") %>' width="35px" /> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtBlack_Reorder_Limit" runat="server" Text='<%# Eval("Black_Reorder_Limit") %>' width="35px" /> <asp:RequiredFieldValidator ID="rfvBlack_Reorder_Limit" runat="server" ControlToValidate="txtBlack_Reorder_Limit" SetFocusOnError="true" ErrorMessage="*" ValidationGroup="CurrentMfg" ForeColor="Red" Font-Bold="true" /> </EditItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Notes"> <ItemTemplate> <asp:Label ID="lblNotes" runat="server" Text='<%# Bind("Notes") %>' width="200px" /> </ItemTemplate> <EditItemTemplate> <asp:TextBox ID="txtNotes" runat="server" Text='<%# Eval("Notes") %>' width="170px" /> </EditItemTemplate> </asp:TemplateField> <asp:CommandField ShowEditButton="True" ShowDeleteButton="false" ValidationGroup="CurrentToner" /> </Columns> </asp:GridView> aspx.cs file: protected void Page_Load(object sender, EventArgs e) { LoadData_TonerBlack(); } private void LoadData_TonerBlack() { dalConsumables_TonerBlack drTonerBlack = new dalConsumables_TonerBlack(); gvBlack.DataSource = drTonerBlack.GetListTonersBlack(); gvBlack.DataBind(); } protected void gvBlack_OnUpdating(object sender, GridViewUpdateEventArgs e) { //GridView gvBlack = (GridView)sender; //GridViewRow gvBlackRow = (GridViewRow)gvBlack.Rows[e.RowIndex]; int _Ident_Black = Convert.ToInt32(gvBlack.DataKeys[e.RowIndex].Values[0].ToString()); TextBox _txtModel_Black = (TextBox)gvBlack.Rows[e.RowIndex].FindControl("txtModel_Black"); TextBox _txtDesc_Black = (TextBox)gvBlack.Rows[e.RowIndex].FindControl("txtDesc_Black"); TextBox _txtQty_Black = (TextBox)gvBlack.Rows[e.RowIndex].FindControl("txtQty_Black"); TextBox _txtBlack_Reorder_Limit = (TextBox)gvBlack.Rows[e.RowIndex].FindControl("txtBlack_Reorder_Limit"); TextBox _txtNotes = (TextBox)gvBlack.Rows[e.RowIndex].FindControl("txtNotes"); string _updatedBy = Request.ServerVariables["AUTH_USER"].ToString(); dalConsumables_TonerBlack updateTonerBlack = new dalConsumables_TonerBlack(); updateTonerBlack.UpdateTonerBlack(_Ident_Black, _txtModel_Black.Text, _txtDesc_Black.Text, Convert.ToInt32(_txtQty_Black.Text), Convert.ToInt32(_txtBlack_Reorder_Limit.Text), _txtNotes.Text, _updatedBy); gvBlack.EditIndex = -1; LoadData_TonerBlack(); } protected void gvBlack_RowEditing(object sender, GridViewEditEventArgs e) { gvBlack.EditIndex = e.NewEditIndex; LoadData_TonerBlack(); } Thanks in advance!

a friendly elaboratation on how iceweasel misses as recent request was discovered in post tut

- by v3x3n

I would like to specify what you asked about in how iceweasel misses on in hopes that you are interested in considering the answer to be valid considering the package should run efficient to a novice user especially when getting a first impression on a new software, browser, or package they are given by default. First let me say that I am very grateful for all debian has and continues to do for its user base and I am not complaining, only hoping that in mentioning such it will eventually aid in improving the disappointing experience iceweasel gave me in multiple ways right from the start of using it. I am sure tremendous amounts of hard work went into making it work as well as it does, and tremendous effort continues to go into IW like the rest of the package and distros such as this... Having said that, I do aim to keep my examples simple as possible but also explained in enough detail as to not leave out important info to get a full idea of my issue... (Thanks for understanding if I sound novice to debian, I am but continue to learn and advance by trial and error each day, and of course the wonderful help from all the great minds available here and there)... Well, my bone to pick (unfortunately as I disdain being a complainer when so much has been done for us, the end user) with IW is mainly 3 immediately noticed problems in offering me a smooth test drive (completely normal browsing conduct of your average user, I should indicate) as soon as I started out a task using IW (heading directly to google images and searched for a few web sized images, then saved a few (no more than 800 to 900 in dimensions, typically a normal procedure I would imagine) I experienced a horrendous reoccurring freeze and lag time that almost left me to kill the process more than once on each attempt and continued to compound so that by a few attempts later, even 1 single image save locked up the entire browser, ultimately giving up on my procedure in its simplicity with a bit of aggravation, if there was something I had done wrong on my end pre-attempt or during installation. Secondly, visiting video player sites in this case youtube will not allow for any video feed to play whatsoever and again, experienced a slight freezing that eventually dissipated as long as I didn't attempt to press play or reload another video trial... Very annoying and possibly related to my first issue (which could rely on my own lack of knowledge in setup config, but that troubles me if so).... Lastly as another user has stated already, in which brought you to ask them what exactly seemed to be the problem in the first place is also my final straw that broke the weasel's back, leading me here to find a solution to a updated version of firefox... being that iceweasel (an apparent build of firefox 17.x.x) leaving the user to find themselves out of luck when installing their favorite or much useful add-ons or plugins that aid their task or normal usage online.... As the other user clearly stated... there is almost zero options and barely any luck to find compatible plugins with such an outdated version still being used... I can only imagine if as a novoice or standard user to linux... and beginner to debian (which I am all for btw!) if I am discovering major conductivity issues which hinder normal user conduct right off the bat... that there is probably a bundle or more of security vulnerabilities that would unravel to me if I continued to give mr Hommey's package any further attention, or interest in continuing to use... This is a deal breaker on any account, unless all 3 of these issues stated are due to a very n00berish setting or lack thereof (which if that is the case, such was not properly stated for beginner in any place available by following installation tutorials such as LVM installers, which I felt lacked a clear understanding to someone who is trying to learn why and how, rather than, a fix to a potentially broken out of box installation... I really think that is irrelevant in any case however, as there is much step by step support regarding that kind of thing, just saying... its very challenging, along side a job to keep deadlines on, and the need to learn a better and more costomizible system, that was not as popularized when I became a dev via windows (OK OK I know thats a huge mistake and now I am way off original topic but anyway) Thanks very much for taking the time to read over this, and I hope it honestly gives you a few good and valid reasons for users wanting and seeking a way to get around iceweasel altogether... Finally, if I am missing something vital that renders all I've stated invalid or useless, please feel free to shove that elephant in the room my direction! Thanks for all you do, as I am sure it is very useful and dedicated, being you are a debian maintainer, and super user! Much love for intelligence, freedom and sharing the secrets of the web! May it remain unregulated and a good place to grow and learn for generations to come! Stay true! Take care now! -v3x (v3x @ gmx .com)

What needs updating when moving a bootable Windows 7 (or Vista) partition?

- by SuperTempel

When I move a bootable NTFS partition with Windows on it to a different block offset, what needs updating to make it bootable again? In particular, here's what I tried: I have a disk with several partitions, one of which is the NTFS partition with Windows on it, and the disk uses the plain old MBR block 0 for the partitions layout (no more than 4 partitions). Now I format and partition a new, larger, disk. There I make room for the NTFS partition and copy the contents from the old disk's NTFS Windows partition into. And I make the partition "active". However, when I try to boot from this disk, I get a "read error" message immediately and the booting stops, the exact text is: A disk read error occurred Press Ctrl+Alt+Del to restart I verified that both disks have the same boot sector code in block 0. It seems to me that something else might need updating. I guess that somewhere there's a absolute block reference that I need to update, probably pointing to the next level loader or to the NT kernel. Update: I found this article going quite into the depth of what I want to know. However, it says to modify boot.ini, but I have Windows 7 installed here, where such things appear to have changed: No boot.ini but a folder called System Volume Information with GUID and other data in it that sounds related to my problem. Going to keep digging... Update 2: Thanks to the terrible looking but very informative website by starman, I was able to figure out the first step: The NTFS boot sector has a field for "hidden" sectors. This feld has to contain the sector number of the boot sector. This solves the "read error" message. Now, however, I get a "BOOTMGR is missing" error instead. Looks like there's another place where a block number has to be adjusted, but I can't find anything in the code listing about this. I do find a lot of help sites suggesting Windows tools for fixing this "BOOTMGR is missing" problem, but none seem to know what goes on behind the scenes. Kind of like suggesting to re-install Windows when there's a little problem with it. At least, those fixes seem to work, mostly involving the Bcdedit and Bootrec tools. Now, who knows what they do, especially the latter, in regards to a moved partition? Update 3: After lots of trial-and-error attempts, I believe now that the solution lies in the BCD-Template registry file, residing usually inside \Windows\System32\config. If I get this updated using the "bcdboot" command, Windows starts up from it. I am now in the middle of figuring out what information this registry contains relevant to the above question. Any pointers to the contents of this registry are welcome. Update 4: Turns out that while the BCD-Template file gets rewritten and has different binary contents than its predecessor, the values inside do not change. So it must be something else that bcdboot.exe writes. I had previously already checked if it changes the first 32 boot blocks of the partition, but they appear to remain unchanged. Parititon map doesn't get changed, either. So what is it that bcdboot modifies besides the BCD registry? Any tips on how I can trace that? Are there low level tools that show me what files a program writes to? Update 5: The answer seems to be: c:\Boot\BCD is also changed, and that appears to be the key file for the boot manager's process. I'll investigate this later... Update 6: It seems to be an important detail that I had originally two partitions created when I installed Windows 7: A small partition of 204800 sectors which appears to be a bootstrap partition, followed by the actual, large, partition containing the Windows system (drive C:). When I tried to transfer this installation to a new, larger, disk, I had kept the same two partitions intact on the new drive, although they ended up at a different offset. This alone led to the "BOOTMGR is missing" message. Since then, I've used bcdboot.exe only on the Windows partition, which added the \Boot\BCD file on that partition. That file (and folder) did originally only exist on the smaller partition. Hence, this problem may be more complicated in my case as one partition (the boot strapper) referred to another partition (the one containing the OS), whereas other people may only have to deal with one partition containing both, and maybe there the solution is simpler. Update 7: Found one more detail: The \Boot\BCD file records the MBR's serial number. If that number doesn't match, the system won't boot. Next I'll test if there's also an absolute block reference stored in there.
