• Postfix - am I sending spam?

  - by olrehm

  today I received like 30 messages within 5 minutes telling me that some mail I send could not be delivered, mostly to *.ru email addresses which I did not send any mail to. I have my own webserver (postfix/dovecot) set up using this guide (http://workaround.org/ispmail/lenny) but adjusted a little bit for Ubuntu. I tested whether I am an Open Relay which I am apparently not. Now there are two possible reasons for the above mentioned emails: Either I am sending out spam, or somebody wants me to think that, correct? How can I check this? I selected one particular address that I supposedly send spam to. Then I searched my mail.log for this entry. I found two blocks that record that somebody from the server connected to my server and delivered some message to two different users. I cannot find an entry reporting that anyone from my server send an email to that server. Does this mean its just some mail to scare me or could it still have been send by me in the first place? Here is one such block from the log (I replaced some confidential stuff): Jun 26 23:23:28 mycustomernumber postfix/smtpd[29970]: connect from mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber postfix/smtpd[29970]: 044991528995: client=mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber postfix/cleanup[29974]: 044991528995: message-id=<[email protected]> Jun 26 23:23:29 mycustomernumber postfix/qmgr[3369]: 044991528995: from=<>, size=2198, nrcpt=1 (queue active) Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) ESMTP::10024 /var/lib/amavis/tmp/amavis-20110626T223137-28598: <> -> <[email protected]> SIZE=2198 Received: from mycustomernumber.stratoserver.net ([127.0.0.1]) by localhost (rehmsen.de [127.0.0.1]) (amavisd-new, port 10024) with ESMTP for <[email protected]>; Sun, 26 Jun 2011 23:23:29 +0200 (CEST) Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) Checking: YakjkrdFq6A8 [195.144.251.97] <> -> <[email protected]> Jun 26 23:23:29 mycustomernumber postfix/smtpd[29970]: disconnect from mx.webstyle.ru[195.144.251.97] Jun 26 23:23:29 mycustomernumber amavis[28598]: (28598-11) lookup_sql_field(id) (WARN: no such field in the SQL table), "[email protected]" result=undef Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: connect from localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: 0A1FA1528A21: client=localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber postfix/cleanup[29974]: 0A1FA1528A21: message-id=<[email protected]> Jun 26 23:23:32 mycustomernumber postfix/qmgr[3369]: 0A1FA1528A21: from=<>, size=2841, nrcpt=1 (queue active) Jun 26 23:23:32 mycustomernumber postfix/smtpd[29979]: disconnect from localhost.localdomain[127.0.0.1] Jun 26 23:23:32 mycustomernumber amavis[28598]: (28598-11) FWD via SMTP: <> -> <[email protected]>,BODY=7BIT 250 2.0.0 Ok, id=28598-11, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 0A1FA1528A21 Jun 26 23:23:32 mycustomernumber amavis[28598]: (28598-11) Passed CLEAN, [195.144.251.97] [195.144.251.97] <> -> <[email protected]>, Message-ID: <[email protected]>, mail_id: YakjkrdFq6A8, Hits: 2.249, size: 2197, queued_as: 0A1FA1528A21, 2882 ms Jun 26 23:23:32 mycustomernumber postfix/smtp[29975]: 044991528995: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=3.3, delays=0.39/0.01/0.01/2.9, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=28598-11, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as 0A1FA1528A21) Jun 26 23:23:32 mycustomernumber postfix/qmgr[3369]: 044991528995: removed Jun 26 23:23:33 mycustomernumber postfix/smtp[29980]: 0A1FA1528A21: to=<[email protected]>, orig_to=<[email protected]>, relay=mx3.hotmail.com[65.54.188.110]:25, delay=1.2, delays=0.15/0.02/0.51/0.55, dsn=2.0.0, status=sent (250 <[email protected]> Queued mail for delivery) Jun 26 23:23:33 mycustomernumber postfix/qmgr[3369]: 0A1FA1528A21: removed Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max connection rate 1/60s for (smtp:195.144.251.97) at Jun 26 23:23:28 Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max connection count 1 for (smtp:195.144.251.97) at Jun 26 23:23:28 Jun 26 23:26:49 mycustomernumber postfix/anvil[29972]: statistics: max cache size 1 at Jun 26 23:23:28 I can provide more info if you tell me what you need to know.

• GeoIP and Nginx

  - by JavierMartinez

  I have a nginx with geoip, but it is not working rightly. The issue is the next: Nginx are getting geodata from $_SERVER['REMOTE_ADDR'] instead of $_SERVER['HTTP_X_HAPROXY_IP'], which have the real client ip. So, the reported geodata belongs to my server ip instead of client ip. Does anybody where could be the error to fix it? Nginx version and compiled modules: nginx -V nginx version: nginx/1.2.3 TLS SNI support enabled configure arguments: --prefix=/etc/nginx --conf-path=/etc/nginx/nginx.conf --error-log- path=/var/log/nginx/error.log --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-log-path=/var/log/nginx/access.log --http-proxy-temp-path=/var/lib/nginx/proxy --http-scgi-temp-path=/var/lib/nginx/scgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi --lock-path=/var/lock/nginx.lock --pid-path=/var/run/nginx.pid --with-pcre-jit --with-debug --with-file-aio --with-http_addition_module --with-http_dav_module --with-http_geoip_module --with-http_gzip_static_module --with-http_image_filter_module --with-http_realip_module --with-http_secure_link_module --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --with-http_xslt_module --with-ipv6 --with-sha1=/usr/include/openssl --with-md5=/usr/include/openssl --with-mail --with-mail_ssl_module --add-module=/usr/src/nginx/source/nginx-1.2.3/debian/modules/nginx-auth-pam --add-module=/usr/src/nginx/source/nginx-1.2.3/debian/modules/nginx-echo --add-module=/usr/src/nginx/source/nginx-1.2.3/debian/modules/nginx-upstream-fair --add-module=/usr/src/nginx/source/nginx-1.2.3/debian/modules/nginx-dav-ext-module --add-module=/usr/src/nginx/source/nginx-1.2.3/debian/modules/nginx-syslog --add-module=/usr/src/nginx/source/nginx-1.2.3/debian/modules/nginx-cache-purge nginx site conf (frontend machine) server { root /var/www/storage; server_name ~^.*(\.)?mydomain.com$; if ($host ~ ^(.*)\.mydomain\.com$) { set $new_host $1.mydomain.com; } if ($host !~ ^(.*)\.mydomain\.com$) { set $new_host www.mydomain.com; } add_header Staging true; real_ip_header X-HAProxy-IP; set_real_ip_from 10.5.0.10/32; location /files { expires 30d; if ($uri !~ ^/files/([a-fA-F0-9]+)_(220|45)\.jpg$) { return 403; } rewrite ^/files/([a-fA-F0-9][a-fA-F0-9])([a-fA-F0-9][a-fA-F0-9])([a-fA-F0-9][a-fA-F0-9])([a-fA-F0-9][a-fA-F0-9])([a-fA-F0-9]+)_(220|45)\.jpg$ /files/$1/$2/$3/$4/$1$2$3$4$5_$6.jpg break; try_files $uri @to_backend; } location /assets { if ($uri ~ ^/assets/r([a-zA-Z0-9]+[^/])(/(css|js|fonts)/.*)) { rewrite ^/assets/r([a-zA-Z0-9]+[^/])/(css|js|fonts)/(.*)$ /assets/$2/$3 break; } try_files $uri @to_backend; } location / { proxy_set_header Host $new_host; proxy_set_header X-HAProxy-IP $remote_addr; proxy_pass http://10.5.0.10:8080; } location @to_backend { proxy_set_header Host $new_host; proxy_pass http://10.5.0.10:8080; } } nginx.conf (backend machine) http{ ... ## # GeoIP Config ## geoip_country /etc/nginx/geoip/GeoIP.dat; # the country IP database geoip_city /etc/nginx/geoip/GeoLiteCity.dat; # the city IP database ... } fastcgi_params (backend machine) ### SET GEOIP Variables ### fastcgi_param GEOIP_COUNTRY_CODE $geoip_country_code; fastcgi_param GEOIP_COUNTRY_CODE3 $geoip_country_code3; fastcgi_param GEOIP_COUNTRY_NAME $geoip_country_name; fastcgi_param GEOIP_CITY_COUNTRY_CODE $geoip_city_country_code; fastcgi_param GEOIP_CITY_COUNTRY_CODE3 $geoip_city_country_code3; fastcgi_param GEOIP_CITY_COUNTRY_NAME $geoip_city_country_name; fastcgi_param GEOIP_REGION $geoip_region; fastcgi_param GEOIP_CITY $geoip_city; fastcgi_param GEOIP_POSTAL_CODE $geoip_postal_code; fastcgi_param GEOIP_CITY_CONTINENT_CODE $geoip_city_continent_code; fastcgi_param GEOIP_LATITUDE $geoip_latitude; fastcgi_param GEOIP_LONGITUDE $geoip_longitude; haproxy.conf (frontend machine) defaults log global option forwardfor option httpclose mode http retries 3 option redispatch maxconn 4096 contimeout 100000 clitimeout 100000 srvtimeout 100000 listen cluster_webs *:8080 mode http option tcpka option httpchk option httpclose option forwardfor balance roundrobin server backend-stage 10.5.0.11:80 weight 1 $_SERVER dump: http://paste.laravel.com/7dy Where 10.5.0.10 is frontend private ip and 10.5.0.11 backend private ip

Could someone help me with this issue? Thank you in advance.

• ImgBurn fails to burn data CD-R disk due to "Layouts do not match" error

  - by 0xAether

  I have a reoccurring problem with the program ImgBurn. Whenever I try and burn anything to a CD-R using ImgBurn it burns just fine, except for when I go and verify the disk. It tells me that the "Layouts do not match". Windows 7 shows the disk as completely blank. Although, I see on the bottom of the disk it has been written to. I can burn ISO files to DVD-R's just fine. This only seems to happen with CD-R's. The CD-R's I'm using are Memorex Cool Colors 52x CD-R's. I have looked on Google, and it seems like I'm not the only one this happens to. Unfortunately, no one is able to provide an explanation. I have included the log file from the last CD I just burnt. If you need anything else to better diagnose this problem, I will gladly provide it. ; //****************************************\\ ; ImgBurn Version 2.5.7.0 - Log ; Monday, 19 November 2012, 16:11:57 ; \\****************************************// ; ; I 16:04:55 ImgBurn Version 2.5.7.0 started!

• Long pause when accessing DFS namespace

  - by Matt

  We've recently migrated our Windows network to use DFS for shared files. DFS is working well, except for one annoying problem: users experience a significant delay when they try to access a DFS namespace that they have not accessed for some time. I have tried to troubleshoot the issue but have not had any success so far, and I was hoping someone here may have some pointers to help resolve the problem. Firstly, some background on our network: The network uses a Windows 2008 functional level Active Directory domain with two Windows 2008 DCs and two DNS servers (one on each of the DCs). The network is DNS only - no WINS. All computers are located at the same site and connected by Gigabit Ethernet. We have approximately 20 Domain-based DFS namespaces in Windows 2008 mode, and each DFS namespace has two Windows 2008 DFS namespace servers (the same two servers for all namespaces). All namespace servers are in FQDN mode and all folder targets are specified using their FQDN. All computers are up-to-date with Service Packs and patches. The actual folder targets (i.e. the SMB shares our DFS folders point to) are scattered across several file and application servers, all running Windows 2008 bar two application servers which run Windows 2003 R2, with no replication setup at all (e.g. all DFS folders currently only have one folder target). Some more detail on the problem: The namespace access delay is generally 1 - 10 seconds long and seems to occur when a particular computer has not accessed the requested namespace for approximately five minutes or more. For example, if the user has not accessed \\domain.name\namespace1\ for more than five minutes and attempts to access \\domain.name\namespace1\ via Windows Explorer, the Explorer window will freeze for 1 - 10 seconds before finally resuming and displaying the folders that exist in \\domain.name\namespace1. If they then close the Explorer window and attempt to access \\domain.name\namespace1\ again within five minutes the contents will be displayed almost instantly - if they wait longer than five minutes it will go through the 1 - 10 second pause again. Once "inside" the namespace everything is nice and snappy, it's just the initial connection to the namespace that is slow. The browsing delays seem to affect all variants of Windows that we use (Windows 2008 x64 SP2, Windows 2003 R2 x86 SP2, Windows XP Pro x86 SP3) - it is possibly a bit worse in Windows XP / 2003 than in Windows 2008, but I'm not sure if the difference isn't just psychological. Accessing the underlying folder targets directly exhibits no delay at all - i.e. if the SMB shares pointed to by DFS are accessed directly (bypassing DFS) then there is no pause. During trouble-shooting I noticed that the "Cache duration" for all of our DFS roots is set to 300 seconds - 5 minutes. Given that this is the same amount of time required to trigger the pause I assume that this caching is somehow related, although I am unsure exactly what is cached on the client and hence what needs to be looked up again after 5 minutes have elapsed. In trying to resolve the problem I have already tried / checked the following (without success): Run dcdiag on both Domain Controllers - no problems found Done some basic DNS server checks without finding any problems - I don't know how to check the DNS servers in detail, but I would add that the network is not exhibiting any other strange behavior that may point to a DNS problem Disabled Anti-virus on clients and servers Removing one of the namespace servers from a couple of namespaces - no difference So that's where I'm up to - and I'm out of ideas. Can anyone suggest what may be causing the delays and/or what I should be trying next?

• Red Hat Yum not working out of the box?

  - by Tucker

  I have a server runnning Red Hat Enterprise Linux v5.6 in the cloud. My project constraints do not allow me to use another OS. When I created the cloud server, I was able to SSH into it and access the shell. I next ran the command: sudo yum update But the command failed. About a month ago I created another server with the same machine image and didn't have that error. Why is it failing now? The following is the terminal output sudo yum update Loaded plugins: security Repository rhel-server is listed more than once in the configuration Traceback (most recent call last): File "/usr/bin/yum", line 29, in ? yummain.user_main(sys.argv[1:], exit_code=True) File "/usr/share/yum-cli/yummain.py", line 309, in user_main errcode = main(args) File "/usr/share/yum-cli/yummain.py", line 178, in main result, resultmsgs = base.doCommands() File "/usr/share/yum-cli/cli.py", line 345, in doCommands self._getTs(needTsRemove) File "/usr/lib/python2.4/site-packages/yum/depsolve.py", line 101, in _getTs self._getTsInfo(remove_only) File "/usr/lib/python2.4/site-packages/yum/depsolve.py", line 112, in _getTsInfo pkgSack = self.pkgSack File "/usr/lib/python2.4/site-packages/yum/__init__.py", line 662, in <lambda> pkgSack = property(fget=lambda self: self._getSacks(), File "/usr/lib/python2.4/site-packages/yum/__init__.py", line 502, in _getSacks self.repos.populateSack(which=repos) File "/usr/lib/python2.4/site-packages/yum/repos.py", line 260, in populateSack sack.populate(repo, mdtype, callback, cacheonly) File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 168, in populate if self._check_db_version(repo, mydbtype): File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 226, in _check_db_version return repo._check_db_version(mdtype) File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1233, in _check_db_version repoXML = self.repoXML File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1406, in <lambda> repoXML = property(fget=lambda self: self._getRepoXML(), File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1398, in _getRepoXML self._loadRepoXML(text=self) File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1388, in _loadRepoXML return self._groupLoadRepoXML(text, ["primary"]) File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1372, in _groupLoadRepoXML if self._commonLoadRepoXML(text): File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 1208, in _commonLoadRepoXML result = self._getFileRepoXML(local, text) File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 989, in _getFileRepoXML cache=self.http_caching == 'all') File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 826, in _getFile http_headers=headers, File "/usr/lib/python2.4/site-packages/urlgrabber/mirror.py", line 412, in urlgrab return self._mirror_try(func, url, kw) File "/usr/lib/python2.4/site-packages/urlgrabber/mirror.py", line 398, in _mirror_try return func_ref( *(fullurl,), **kwargs ) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 936, in urlgrab return self._retry(opts, retryfunc, url, filename) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 854, in _retry r = apply(func, (opts,) + args, {}) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 922, in retryfunc fo = URLGrabberFileObject(url, filename, opts) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 1010, in __init__ self._do_open() File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 1093, in _do_open fo, hdr = self._make_request(req, opener) File "/usr/lib/python2.4/site-packages/urlgrabber/grabber.py", line 1202, in _make_request fo = opener.open(req) File "/usr/lib64/python2.4/urllib2.py", line 358, in open response = self._open(req, data) File "/usr/lib64/python2.4/urllib2.py", line 376, in _open '_open', req) File "/usr/lib64/python2.4/urllib2.py", line 337, in _call_chain result = func(*args) File "/usr/lib64/python2.4/site-packages/M2Crypto/m2urllib2.py", line 82, in https_open h.request(req.get_method(), req.get_selector(), req.data, headers) File "/usr/lib64/python2.4/httplib.py", line 810, in request self._send_request(method, url, body, headers) File "/usr/lib64/python2.4/httplib.py", line 833, in _send_request self.endheaders() File "/usr/lib64/python2.4/httplib.py", line 804, in endheaders self._send_output() File "/usr/lib64/python2.4/httplib.py", line 685, in _send_output self.send(msg) File "/usr/lib64/python2.4/httplib.py", line 652, in send self.connect() File "/usr/lib64/python2.4/site-packages/M2Crypto/httpslib.py", line 47, in connect self.sock.connect((self.host, self.port)) File "/usr/lib64/python2.4/site-packages/M2Crypto/SSL/Connection.py", line 174, in connect ret = self.connect_ssl() File "/usr/lib64/python2.4/site-packages/M2Crypto/SSL/Connection.py", line 167, in connect_ssl return m2.ssl_connect(self.ssl, self._timeout) M2Crypto.SSL.SSLError: certificate verify failed

• Splitting a raidctl mirror safely

  - by milkfilk

  I have a Sun T5220 server with the onboard LSI card and two disks that were in a RAID 1 mirror. The data is not important right now but we had a failed disk and are trying to understand how to do this for real if we had to recover from a failure. The initial situation looked like this: # raidctl -l c1t0d0 Volume Size Stripe Status Cache RAID Sub Size Level Disk ---------------------------------------------------------------- c1t0d0 136.6G N/A DEGRADED OFF RAID1 0.1.0 136.6G GOOD N/A 136.6G FAILED Green light on the 0.0.0 disk. Find / lights up the 0.1.0 disk. So I know I have a bad drive and which one it is. Server still boots obviously. First, we tried putting a new disk in. This disk came from an unknown source. Format would not see it, cfgadm -al would not see it so raidctl -l would not see it. I figure it's bad. We tried another disk from another spare server: # raidctl -c c1t1d0 c1t0d0 (where t1 is my good disk - 0.1.0) Disk has occupied space. Also the different syntax options don't change anything: # raidctl -C "0.1.0 0.0.0" -r 1 1 Disk has occupied space. # raidctl -C "0.1.0 0.0.0" 1 Disk has occupied space. Ok. Maybe this is because the disk from the spare server had a RAID 1 on it already. Aha, I can see another volume in raidctl: # raidctl -l Controller: 1 Volume:c1t1d0 (this is my server's root mirror) Volume:c1t132d0 (this is the foreign root mirror) Disk: 0.0.0 Disk: 0.1.0 ... No problem. I don't care about the data, I'll just delete the foreign mirror. # raidctl -d c1t132d0 (warning about data deletion but it works) At this point, /usr/bin/ binaries freak out. By that I mean, ls -l /usr/bin/which shows 1.4k but cat /usr/bin/which gives me a newline. Great, I just blew away the binaries (ie: binaries in mem still work)? I bounce the box. It all comes back fine. WTF. Anyway, back to recreating my mirror. # raidctl -l Controller: 1 Volume:c1t1d0 (this is my server's root mirror) Disk: 0.0.0 Disk: 0.1.0 ... Man says that you can delete a mirror and it will split it. Ok, I'll delete the root mirror. # raidctl -d c1t0d0 Array in use. (this might not be the exact error) I googled this and found of course you can't do this (even with -f) while booted off the mirror. Ok. I boot cdrom -s and deleted the volume. Now I have one disk that has a type of "LSI-Logical-Volume" on c1t1d0 (where my data is) and a brand new "Hitachi 146GB" on c1t0d0 (what I'm trying to mirror to): (booted off the CD) # raidctl -c c1t1d0 c1t0d0 (man says it's source destination for mirroring) Illegal Array Layout. # raidctl -C "0.1.0 0.0.0" -r 1 1 (alt syntax per man) Illegal Array Layout. # raidctl -C "0.1.0 0.0.0" 1 (assumes raid1, no help) Illegal Array Layout. Same size disks, same manufacturer but I did delete the volume instead of throwing in a blank disk and waiting for it to resync. Maybe this was a critical error. I tried selecting the type in format for my good disk to be a plain 146gb disk but it resets the partition table which I'm pretty sure would wipe the data (bad if this was production). Am I boned? Anyone have experience with breaking and resyncing a mirror? There's nothing on Google about "Illegal Array Layout" so here's my contrib to the search gods.

• Increase samba space on open suse 12.1

  - by Kapil Sharma

  I know linux basics but not an expert. IT guy left the job here and there is some time before new hire. So sorry if question is very basic. We have local testing server based on Open SUSE 12.1, which also act as shared drive between dev/mgmt team here and using Samba for that. Now we are running out of space on samba, even though server's 2*1TB harddisk is nearly 90% free. My question is, what is limiting Samba and how can I increase its limit? We need around at least 500 GB as shared drive but currently its just 25 GB. I don't need step by step answer, just a link to any helpful article would be sufficient. Probably I'm putting wrong keywords in google so not getting any helpful link. EDIT: Output of commands in the first comment. All commands were run as root user df -h (getting error with df -ht) Filesystem Size Used Avail Use% Mounted on rootfs 30G 5.1G 23G 19% / devtmpfs 2.0G 36K 2.0G 1% /dev tmpfs 2.0G 1.1M 2.0G 1% /dev/shm tmpfs 2.0G 676K 2.0G 1% /run /dev/sda2 30G 5.1G 23G 19% / tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup tmpfs 2.0G 676K 2.0G 1% /var/run tmpfs 2.0G 0 2.0G 0% /media tmpfs 2.0G 676K 2.0G 1% /var/lock /dev/sda3 36G 31G 3.3G 91% /home fdisk -l /dev/[hmsv]d* Disk /dev/sda: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders, total 156301488 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x2d4a2d49 Device Boot Start End Blocks Id System /dev/sda1 2048 16771071 8384512 82 Linux swap / Solaris /dev/sda2 * 16771072 79681535 31455232 83 Linux /dev/sda3 79681536 156301311 38309888 83 Linux Disk /dev/sda1: 8585 MB, 8585740288 bytes 255 heads, 63 sectors/track, 1043 cylinders, total 16769024 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sda1 doesn't contain a valid partition table Disk /dev/sda2: 32.2 GB, 32210157568 bytes 255 heads, 63 sectors/track, 3915 cylinders, total 62910464 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System Disk /dev/sda3: 39.2 GB, 39229325312 bytes 255 heads, 63 sectors/track, 4769 cylinders, total 76619776 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sda3 doesn't contain a valid partition table vgs No volume groups found lvs No volume groups found output of vi /etc/samba/smb.conf # smb.conf is the main Samba configuration file.

• Determining cause of high NFS/IO utilization without iotop

  - by Matt

  I have a server that is doing an NFSv4 export for user's home directories. There are roughly 25 users (mostly developers/analysts) and about 40 servers mounting the home directory export. Performance is miserable, with users often seeing multi-second lags for simple commands (like ls, or writing a small text file). Sometimes the home directory mount completely hangs for minutes, with users getting "permission denied" errors. The hardware is a Dell R510 with dual E5620 CPUs and 8 GB RAM. There are eight 15k 2.5” 600 GB drives (Seagate ST3600057SS) configured in hardware RAID-6 with a single hot spare. RAID controller is a Dell PERC H700 w/512MB cache (Linux sees this as a LSI MegaSAS 9260). OS is CentOS 5.6, home directory partition is ext3, with options “rw,data=journal,usrquota”. I have the HW RAID configured to present two virtual disks to the OS: /dev/sda for the OS (boot, root and swap partitions), and /dev/sdb for the home directories. What I find curious, and suspicious, is that the sda device often has very high utilization, even though it only contains the OS. I would expect this virtual drive to be idle almost all the time. The system is not swapping, according to "free" and "vmstat". Why would there be major load on this device? Here is a 30-second snapshot from iostat: Time: 09:37:28 AM Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 44.09 0.03 107.76 0.13 607.40 11.27 0.89 8.27 7.27 78.35 sda1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sda2 0.00 44.09 0.03 107.76 0.13 607.40 11.27 0.89 8.27 7.27 78.35 sdb 0.00 2616.53 0.67 157.88 2.80 11098.83 140.04 8.57 54.08 4.21 66.68 sdb1 0.00 2616.53 0.67 157.88 2.80 11098.83 140.04 8.57 54.08 4.21 66.68 dm-0 0.00 0.00 0.03 151.82 0.13 607.26 8.00 1.25 8.23 5.16 78.35 dm-1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-2 0.00 0.00 0.67 2774.84 2.80 11099.37 8.00 474.30 170.89 0.24 66.84 dm-3 0.00 0.00 0.67 2774.84 2.80 11099.37 8.00 474.30 170.89 0.24 66.84 Looks like iotop is the ideal tool to use to sniff out these kinds of issues. But I'm on CentOS 5.6, which doesn't have a new enough kernel to support that program. I looked at Determining which process is causing heavy disk I/O?, and besides iotop, one of the suggestions said to do a "echo 1 /proc/sys/vm/block_dump". I did that (after directing kernel messages to tempfs). In about 13 minutes I had about 700k reads or writes, roughly half from kjournald and the other half from nfsd: # egrep " kernel: .*(READ|WRITE)" messages | wc -l 768439 # egrep " kernel: kjournald.*(READ|WRITE)" messages | wc -l 403615 # egrep " kernel: nfsd.*(READ|WRITE)" messages | wc -l 314028 For what it's worth, for the last hour, utilization has constantly been over 90% for the home directory drive. My 30-second iostat keeps showing output like this: Time: 09:36:30 PM Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 6.46 0.20 11.33 0.80 71.71 12.58 0.24 20.53 14.37 16.56 sda1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sda2 0.00 6.46 0.20 11.33 0.80 71.71 12.58 0.24 20.53 14.37 16.56 sdb 137.29 7.00 549.92 3.80 22817.19 43.19 82.57 3.02 5.45 1.74 96.32 sdb1 137.29 7.00 549.92 3.80 22817.19 43.19 82.57 3.02 5.45 1.74 96.32 dm-0 0.00 0.00 0.20 17.76 0.80 71.04 8.00 0.38 21.21 9.22 16.57 dm-1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-2 0.00 0.00 687.47 10.80 22817.19 43.19 65.48 4.62 6.61 1.43 99.81 dm-3 0.00 0.00 687.47 10.80 22817.19 43.19 65.48 4.62 6.61 1.43 99.82

• how to make bridge networking with KVM work in Fedora19

  - by netllama

  I'm attempting to get several virtual machines setup on a Fedora-19 host system, with the traditional bridge network devices (br0, br1, etc). I've done this many times before with older versions of Fedora (16, 14, etc), and it just works. However, for reasons that I cannot figure out, the bridge doesn't seem to be working in Fedora19. While I can successfully connect to the outside world (local network + internet) from inside a VM, nothing can communicate with the VM from outside (local network). I'm referring to something as trivial as pinging. From inside the VM, I can ping anything successfully (0% packet loss). However, from outside the VM (on the host, or any other system on the same network), I see 100% packet loss when pinging the IP address of the VM. My first question is simply, does anyone else have this working successfully in F19? And if so, what steps did you need to follow? I'm not using NetworkManager at all, its all the network service. There are no firewalls involved anywhere (iptables & firewall services are currently disabled). Here's the current host configuration: # brctl show bridge name bridge id STP enabled interfaces br0 8000.38eaa792efe5 no em2 vnet1 br1 8000.38eaa792efe6 no em3 br2 8000.38eaa792efe7 no em4 vnet0 virbr0 8000.525400db3ebf yes virbr0-nic # more /etc/sysconfig/network-scripts/ifcfg-em2 TYPE=Ethernet BRIDGE="br0" NAME=em2 DEVICE="em2" UUID=aeaa839e-c89c-4d6e-9daa-79b6a1b919bd ONBOOT=yes HWADDR=38:EA:A7:92:EF:E5 NM_CONTROLLED="no" # more /etc/sysconfig/network-scripts/ifcfg-br0 TYPE=Bridge NM_CONTROLLED="no" BOOTPROTO=dhcp NAME=br0 DEVICE="br0" ONBOOT=yes # ifconfig em2 ;ifconfig br0 em2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 fe80::3aea:a7ff:fe92:efe5 prefixlen 64 scopeid 0x20<link> ether 38:ea:a7:92:ef:e5 txqueuelen 1000 (Ethernet) RX packets 100093 bytes 52354831 (49.9 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 25321 bytes 15791341 (15.0 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device memory 0xf7d00000-f7e00000 br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.31.99.226 netmask 255.255.252.0 broadcast 10.31.99.255 inet6 fe80::3aea:a7ff:fe92:efe5 prefixlen 64 scopeid 0x20<link> ether 38:ea:a7:92:ef:e5 txqueuelen 0 (Ethernet) RX packets 19619 bytes 1963328 (1.8 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 11 bytes 1074 (1.0 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Relevant section from /etc/libvirt/qemu/foo.xml (one of the VMs with this problem): <interface type='bridge'> <mac address='52:54:00:26:22:9d'/> <source bridge='br0'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> # ps -ef | grep qemu qemu 1491 1 82 13:25 ? 00:42:09 /usr/bin/qemu-system-x86_64 -machine accel=kvm -name cuda-linux64-build5 -S -machine pc-0.13,accel=kvm,usb=off -cpu SandyBridge,+pdpe1gb,+osxsave,+dca,+pcid,+pdcm,+xtpr,+tm2,+est,+smx,+vmx,+ds_cpl,+monitor,+dtes64,+pbe,+tm,+ht,+ss,+acpi,+ds,+vme -m 16384 -smp 6,sockets=6,cores=1,threads=1 -uuid 6e930234-bdfd-044d-2787-22d4bbbe30b1 -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/cuda-linux64-build5.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/var/lib/libvirt/images/cuda-linux64-build5.img,if=none,id=drive-virtio-disk0,format=raw,cache=writeback -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,fd=25,id=hostnet0,vhost=on,vhostfd=26 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:26:22:9d,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -vnc 127.0.0.1:1 -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 I can provide additional information, if requested. thanks!

• How do I get my ubuntu server to listen for database connections?

  - by Bob Flemming

  I am having a problems connecting to my database outside of phpmyadmin. Im pretty sure this is because my server isn't listening on port 3306.

• Memcached Lagging

  - by Brad Dwyer

  Let me preface this by saying that this is a followup question to this topic. That was "solved" by switching from Solaris (SmartOS) to Ubuntu for the memcached server. Now we've multiplied load by about 5x and are running into problems again. We are running a site that is doing about 1000 requests/minute, each request hits Memcached with approximately 3 reads and 1 write. So load is approximately 65 requests per second. Total data in the cache is about 37M, and each key contains a very small amount of data (a JSON-encoded array of integers amounting to less than 1K). We have setup a benchmarking script on these pages and fed the data into StatsD for logging. The problem is that there are spikes where Memcached takes a very long time to respond. These do not appear to correlate with spikes in traffic. What could be causing these spikes? Why would memcached take over a second to reply? We just booted up a second server to put in the pool and it didn't make any noticeable difference in the frequency or severity of the spikes. This is the output of getStats() on the servers: Array ( [-----------] => Array ( [pid] => 1364 [uptime] => 3715684 [threads] => 4 [time] => 1336596719 [pointer_size] => 64 [rusage_user_seconds] => 7924 [rusage_user_microseconds] => 170000 [rusage_system_seconds] => 187214 [rusage_system_microseconds] => 190000 [curr_items] => 12578 [total_items] => 53516300 [limit_maxbytes] => 943718400 [curr_connections] => 14 [total_connections] => 72550117 [connection_structures] => 165 [bytes] => 2616068 [cmd_get] => 450388258 [cmd_set] => 53493365 [get_hits] => 450388258 [get_misses] => 2244297 [evictions] => 0 [bytes_read] => 2138744916 [bytes_written] => 745275216 [version] => 1.4.2 ) [-----------:11211] => Array ( [pid] => 8099 [uptime] => 4687 [threads] => 4 [time] => 1336596719 [pointer_size] => 64 [rusage_user_seconds] => 7 [rusage_user_microseconds] => 170000 [rusage_system_seconds] => 290 [rusage_system_microseconds] => 990000 [curr_items] => 2384 [total_items] => 225964 [limit_maxbytes] => 943718400 [curr_connections] => 7 [total_connections] => 588097 [connection_structures] => 91 [bytes] => 562641 [cmd_get] => 1012562 [cmd_set] => 225778 [get_hits] => 1012562 [get_misses] => 125161 [evictions] => 0 [bytes_read] => 91270698 [bytes_written] => 350071516 [version] => 1.4.2 ) ) Edit: Here is the result of a set and retrieve of 10,000 values.

• How to diagnose computer lockup/freezing problem

  - by Scott Mitchell

  I built a desktop computer a couple years back with the following specs: CPU: Intel Core 2 Quad Q9300 Yorkfield 2.5GHz 6MB L2 Cache LGA 775 95W Quad-Core Processor BX80580Q9300 Motherboard: EVGA 122-CK-NF68-T1 LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard Video Card: Two EVGA 256-P2-N758-TR GeForce 8600GT SCC 256MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card PSU: SeaSonic S12 Energy Plus SS-550HT 550W ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply Memory: Two G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBPQ Since its inception, the machine has periodically locked up, the regularlity having varied over the years from once a day to once a month. Typically, lockups happen once every few days. By "lockup" I mean my computer just freezes. The screen locks up, I can't move the mouse. Hitting keys on my keyboard that normally turn LEDs on or off on the keyboard (such as Caps Lock) no longer turn the LEDs on or off. If there was music playing at the time of the lockup, noise keeps coming out of the speakers, but it's just the current frequency/note that plays indefinitely. There is no BSOD. When such a lockup occurs I have to do a hard reboot by either turning off the computer or hitting the reset button. I have the most recent version of the NVIDIA hardware drivers, and update them semi-regularly, but that hasn't seemed to help. I am currently using Windows 7 x64, but was previously using Windows Server 2003 x64 and having the same lockup issues. My guess is that it's somehow video driver or motherboard related, but I don't know how to go about diagnosing this problem to narrow down which of the two is the culprit. Additional information re: cooling Regarding cooling... I've not installed any after-market cooling systems aside from two regular fans I scavenged from an older computer. The fan atop the CPU is the one that shipped with it. One of the two scavenged fans I added it located at the bottom tower of the corner, in an attempt to create some airflow from front to back. The second fan is pointed directly at the two video cards. SpeedFan installation and readings Per studiohack's suggestion, I installed SpeedFan, which provided the following temperature readings: GPU: 63C GPU: 65C System: 76C CPU: 64C AUX: 36C Core 0: 78C Core 1: 76C Core 2: 79C Core 3: 79C Update #3: Another Lockup :-( Well, I had another lockup last night. :-( SpeedFan reported the CPU temp at 38 C when it happened, and there was no spike in temperature leading up to the freeze. One thing I notice is that the freeze seems more likely to happen if I am watching a video. In fact, of the last 5 freezes over the past month, 4 of them have been while watching a video on Flickr. Not necessarily the same video, but a video nevertheless. I don't know if this is just coincidence or if it means anything. (As an aside, each night before bedtime my 2 year old daughter sits on my lap and watches some home videos on Flickr and, in the last month, has learned the phrase, "Uh oh, computer broke.") Update #4: MemTest86 and 3DMark06 Test Results: Per suggestions in the comments, I ran the MemTest86 overnight and it cycled through the 8 GB of memory 5 times without error. I also ran the 3DMark06 test without a problem (see my scores at http://3dmark.com/3dm06/15163549). So... what now? :-) Any further suggestions on what to check? Is there some way to get a stack trace or something when the computer locks like that? Thanks

• after enabling mod ssl apache stops listening on port 80

  - by zensys

  I have an ubuntu 12.04 server with zend server CE installed. I now wanted to enable https but after the first steps according to the documentation, 'a2enmod ssl' and 'apache service restart', apache does not listen on 443 but neither on 80, according to netstat -tap | grep http(s)! This is what I see in my error log, but I can't make much of it: [Fri May 25 19:52:39 2012] [notice] caught SIGTERM, shutting down [Fri May 25 19:52:41 2012] [warn] Init: Session Cache is not configured [hint: SSLSessionCache] [Fri May 25 19:52:41 2012] [notice] ModSecurity for Apache/2.6.3 (http://www.modsecurity.org/) configured.

• How can I tell Firefox to ignore unprintable characters?

  - by BrianH

  Edit: Summary Apparently the intended character to display in this case is an "en-dash". This page has a table half way down that shows that for the &ndash;, some software will convert the correct hex code of 2013 to 0096. (look at the first row in the table). This answer on Stackoverflow explains that somehow this is a mixup between Windows-1252 and UTF-8 This blog article enforces this: Character 150 (0x96) is the unicode character "START OF GUARDED AREA" in the non-displayed C1 control character range, but in the Windows-1252 encoding it's mapped to to the displayable character 0x2013 "en-dash" (a short dash). Others have struggled with this when producing content, as this answer on Stackoverflow shows how to replace 0x0096 with 0x2013. Google must realize this, because as stated in my original question below, Google's cached version of the Amazon page has &ndash; so it seems they are automatically correcting these mistakes on pages they cache. I have tried setting my encoding to Windows-1252 but that does not help. So now I guess my question is, how can I tell Firefox to ignore unprintable characters like these? Original content below: (Firefox 3.6.13 on Windows XP) Every once in a while I notice an odd character on certain web pages when browsing the web. It is a outline of a box with a 4-digit number inside. And example of a page that has these characters is: http://aws.amazon.com/ec2/#highlights After each section heading (Elastic, Completely Controlled, ...) I see a box with the number "0096" inside. I looked at the cached version on Google, and google has &ndash; in it's place, so I'm guessing I should be seeing a dash there instead of the box with the numbers in it. I have tried changing the character encoding in Firefox but haven't been able to find one that shows these characters correctly. Is there a way to allow Firefox to view these characters? Thanks in advance! Edit - adding a screen shot of the "special" characters: Edit #2 - tried in Ubuntu - new screenshots I logged into my Ubuntu desktop and browsed to the amazon page in Chrome and Firefox. Chrome completely ignores character, even if I inspect or view page source. Firefox in Unbutu displays the character exactly like Firefox on my Windows XP box. I copied the character and played around with it at the command line - here is a screenshot of the results: It looks like I can paste the character into this post as well: `` It is definitely not isolated to Windows XP. I tried setting the character encoding for my terminal to Windows 1252 (from Dennis' comment below), but then it just displays this character as a question mark. I pulled the webpage down with wget and with curl, and both outputs show this characters as: <96> It makes me wonder if this character renders correctly for anyone? It appears webkit just ignores it, my IE6 ignores it, Firefox displays the box with the numbers in it. I would have to imagine the design team at Amazon can see it correctly? It's not a huge deal to get these characters displaying correctly, but it would be nice to know if there is a solution to this.
