• I don't have permission on my own machine?

  - by Webnet

  I'm running Ubuntu desktop and I don't have permission to modify some local files on my computer. IE - within /var/www/ I can't create a new folder unless I sudo. How do I fix it so by default I have permission without logging in as the root user?

• MySQL: Bind to more than one IP address?

  - by BlaM

  Is there a secret way to bind MySQL to more than one IP address? As far as I can see the bind-address parameter in the my.cnf does not support more than one IP and you can't have it more than once.

• adress-chunk: separate data stored in one collumn - into three (street, postal-code, town)

  - by zero

  hello dear community. Hello dear friends form all over the planet first of all - this is a great great forum. I like this place to share the ideas. It is so great to see such a supportive place - featuring the knowledge exchange! today i have the following thing to discuss: i want to separate the following data that are stored in one column of a calc-spreadsheet: See the following data: You see that there are the following categories:_ steet, postal-code, town All the data are stored in only one Colum; Well to be honest: i want to separate them into three colums steet, postal-code, town see the data: what can i do? note - you see that there are commas inbetween the enties: and besides this we see that we have a postal-code with four digits: that is a good thing. Perhaps we can use this as a marker that helps us to separate the data?! Perhaps See a data-sample! Here you can see some exceptions: eg. the town that has two words combinde with a "-" ... or somethims without any signs and characters... see the following... as an example: Max-Bader-Platz 1, 5620 Schwarzach im Pongau Pestalozzistraße 4, 9990 Nussdorf-Debant Schulstraße 4, 5162 Obertrum am See But i guess that this means no problem... What do you think about this? I am very very interested to get your opinion! i look forward to hear from you! regards see a snipped of the dataset - that is stored in one column -[b]Goal: [/b]i want to separate the datas into three collumns... : Schulweg 6, 9871 Seeboden Khevenhüllerstraße 45, 4861 Schörfling Franz Xaver Rennstr.18, 6460 Imst Schulstraße 4, 5162 Obertrum am See Schulweg 6, 7432 Oberschützen Pestalozzistraße 4, 9990 Nussdorf-Debant Niederndorf bei Kufstein 53c, 6342 Niederndorf bei Kufstein Hauptschulstraße 18, 2183 Neusiedl an der Zaya Seeweg 14, 5202 Neumarkt am Wallersee Europaplatz 1, 8820 Neumarkt in Steiermark Schulstraße 7, 4212 Neumarkt im Mühlkreis Schulstraße 20, 4720 Neumarkt im Hausruckkreis Bahnhofstr. 10, 4872 Neukirchen an der Vöckla Schulstraße 5b, 4780 Schärding Reitbergstraße 2, 4311 Schwertberg Europaplatz 1, 2320 Schwechat Am Schulberg 5, 3931 Schweiggers Waidach 8, 6130 Schwaz Waidach 8, 6130 Schwaz Max-Bader-Platz 1, 5620 Schwarzach im Pongau Markt 29, 2662 Schwarzau im Gebirge Hofsteigstraße 68, 6858 Schwarzach Gmundner Straße 7, 4690 Schwanenstadt Mühlfeldstraße 1, 4690 Schwanenstadt Mainsdorferstraße 18, 8541 Schwanberg Jakob Stemer-Weg 3, 6780 Schruns Obere Umfahrungsstraße 16, 2432 Schwadorf bei Wien Battloggstraße 54, 6780 Schruns Schloss-Straße 19, 5020 Salzburg Schillerplatz 2, 8280 Fürstenfeld Erzherzog-Johann-Str. 400, 8970 Schladming Schulgasse 261, 8811 Scheifling i look forward to hear from you!! regards

• synchronous network audio

  - by intuited

  I'd like to have an audio transmission shared among computers on a LAN. Although there are various systems to do this -- shoutcast/icecast, pulseaudio, etc. -- I'm not aware of any that provide synchronization. I'd like to have different computers in the house playing the same audio, and have the same sample playing at the same time. Is there a system which can do this?

• Heartbeat won't start up from a cold boot when a failed node is present

  - by Matthew

  I currently have two ubuntu servers running Heartbeat and DRBD. Let's say one node is down... The servers are directory connected with a 1000Mbps cross over cable on eth1 and have access to a IP camera LAN on eth0 The node that is still functioning won't start up heartbeat and provide access to the drbd resource. I have to manually restart heartbeat by "sudo service heartbeat restart" to get everything up and running. How can I get it to start fine from a cold start? Here is the my ha.cf and some material from the syslog... If I'm missing any information that might be of some help. http://pastebin.com/rGvzVSUq <--- Syslog http://pastebin.com/VqpaPSb5 <--- ha.cf

• Will these instructions work when turning of journaling on a n ext4 SSD?

  - by snowlord

  I have an Acer Aspire One with an SSD for storage. I recently installed Ubuntu on it and chose ext4 for my filesystem. Then I read that journaling on an SSD isn't the best idea, so I will try to disable journaling and I have found these intstructions (from http://fenidik.blogspot.com/2010/03/ext4-disable-journal.html): # Create ext4 fs on /dev/sda10 disk mkfs.ext4 /dev/sda10 # Enable writeback mode. This mode will typically provide the best ext4 performance. tune2fs -o journal_data_writeback /dev/sda10 # Delete has_journal option tune2fs -O ^has_journal /dev/sda10 # Required fsck e2fsck -f /dev/sda10 # Check fs options dumpe2fs /dev/sda10 |more For more performance add fstab opions: data=writeback,noatime,nodiratime i.e: /dev/sda10 /opt ext4 defaults,data=writeback,noatime,nodiratime 0 0 I will use them on my boot partition. Are there any particularly bad parts here, or are there any missing steps? Will my boot partition be fit for being on an SSD after this? Or should I consider switching to ext2, or even reinstall it all and choose ext2 at partitioning time (I'd rather not though, since I've configured quite some stuff already)?

• Application to store/browse/view photos?

  - by amorfis

  I am looking for application which I can install on Ubuntu server and put my photos there. It can be by web interface, it can be by mounted samba disk. What I require: Ability to add tags to photos. Ability to move photos. I.e. if I set photos directory to /home/photos, but then I want to move all photos to e.g. /home/common/photos - I don't want to lose all the tags. I used to use FSpot and it was great, but it lacked point 2, and I lost everything :(

• postfix "mail-pipe" alias shellscript creates permissionless files/dirs

  - by Gung Foo

  I am using an alias to a shellscript in postfix... After the script that is called by the shellscript creates a directory it has no permissions at all.. #!/bin/sh umask 002 cat | php /var/www/html/catchmymail rcvemail result is like this: d--------- 2 apache apache 4096 Sep 17 17:25 50 it works for files tho: -rw-rw---- 1 apache apache 5836288 Sep 18 11:21 test Not even setting umask 002 in the shellscript before it hands the mail on changes a thing Setting umask(0002) inside catchmymail has no effect either. Has anyone seen this behaviour before or an idea to save my day?!? This is extremely confusing and actually insane behaviour from what i understand about umask and file permissions.

• Website memory problem

  - by Toktik

  I have CentOS 5 installed on my server. I'm in VPS server. I have site where I have constant online ~150. First look on site looks OK. But when I go through links, sometimes I receive Out of memory PHP error. It looks like this Fatal error: Out of memory (allocated 36962304) (tried to allocate 7680 bytes) in /home/host/public_html/sites/all/modules/cck/modules/fieldgroup/fieldgroup.install on line 100 And always, not allocated memory is very small. In average I have 30% CPU load, 25% RAM load. So I think here is not a physical memory problem. My PHP memory limit was set to 1500MB. My apache error log looks like this [Thu Sep 30 17:48:59 2010] [error] [client 91.204.190.5] Out of memory, referer: http://www.host.com/17402 [Thu Sep 30 17:48:59 2010] [error] [client 91.204.190.5] Premature end of script headers: index.php, referer: http://www.host.com/17402 [Thu Sep 30 17:48:59 2010] [error] [client 91.204.190.5] Out of memory, referer: http://www.host.com/17402 [Thu Sep 30 17:48:59 2010] [error] [client 91.204.190.5] Premature end of script headers: index.php, referer: http://www.host.com/17402 [Thu Sep 30 17:49:00 2010] [error] [client 91.204.190.5] File does not exist: /home/host/public_html/favicon.ico Past I have not met with this on my server and the problem appeared itself.

• Remove server hangs, gets stuck. How to debug?

  - by bibstha

  I have an vps running on VmWare ESX with Ubuntu 8.04 LTS. It has been running smoothly for the past 3 months, however recently we've notices two strange bugs. a. The server hangs, today was second time. The nature of the hang is very strange. I can ping to the server server, it sends back response fine. However all other services like sshd, apache, mysql etc do not respond at all. When working, telnet servername 22 Escape character is '^]'. SSH-2.0-OpenSSH_5.X Debian-5ubuntu1 And other web services would run fine. When its hung, I can make tcp connections to 22 as well as 80 but receive no response at all. telnet servername 22 Escape character is '^]'. How can I debug this problem? Is there any daemons I can run that will periodically log status? Please tell me as to how to proceed with it. b. The another strange problem is that, of lately I am unable to transfer files larger than around 100KB, smaller files of around 1-2 KB works file. scp anotherserver:filename . or wget http://www.example.com/file would get stuck. There is still around 6GB of space remaining, so I don't think that is an issue. Any pointers where I should look into?

• "Possible SYN flooding" in log despite low number of SYN_RECV connections

  - by al4

  Recently we had an apache server which was responding very slowly due to SYN flooding. The workaround for this was to enable tcp_syncookies (net.ipv4.tcp_syncookies=1 in /etc/sysctl.conf). I posted a question about this here if you want more background. After enabling syncookies we started seeing the following message in /var/log/messages approximately every 60 seconds: [84440.731929] possible SYN flooding on port 80. Sending cookies. Vinko Vrsalovic informed me that this means the syn backlog is getting full, so I raised tcp_max_syn_backlog to 4096. At some point I also lowered tcp_synack_retries to 3 (down from the default of 5) by issuing sysctl -w net.ipv4.tcp_synack_retries=3. After doing this, the frequency seemed to drop, with the interval of the messages varying between roughly 60 and 180 seconds. Next I issued sysctl -w net.ipv4.tcp_max_syn_backlog=65536, but am still getting the message in the log. Throughout all this I've been watching the number of connections in SYN_RECV state (by running watch --interval=5 'netstat -tuna |grep "SYN_RECV"|wc -l'), and it never goes higher than about 240, much much lower than the size of the backlog. Yet I have a Red Hat server which hovers around 512 (limit on this server is the default of 1024). Are there any other tcp settings which would limit the size of the backlog or am I barking up the wrong tree? Should the number of SYN_RECV connections in netstat -tuna correlate to the size of the backlog? Update As best I can tell I'm dealing with legitimate connections here, netstat -tuna|wc -l hovers around 5000. I've been researching this today and found this post from a last.fm employee, which has been rather useful. I've also discovered that the tcp_max_syn_backlog has no effect when syncookies are enabled (as per this link) So as a next step I set the following in sysctl.conf: net.ipv4.tcp_syn_retries = 3 # default=5 net.ipv4.tcp_synack_retries = 3 # default=5 net.ipv4.tcp_max_syn_backlog = 65536 # default=1024 net.core.wmem_max = 8388608 # default=124928 net.core.rmem_max = 8388608 # default=131071 net.core.somaxconn = 512 # default = 128 net.core.optmem_max = 81920 # default = 20480 I then setup my response time test, ran sysctl -p and disabled syncookies by sysctl -w net.ipv4.tcp_syncookies=0. After doing this the number of connections in the SYN_RECV state still remained around 220-250, but connections were starting to delay again. Once I noticed these delays I re-enabled syncookies and the delays stopped. I believe what I was seeing was still an improvement from the initial state, however some requests were still delayed which is much worse than having syncookies enabled. So it looks like I'm stuck with them enabled until we can get some more servers online to cope with the load. Even then, I'm not sure I see a valid reason to disable them again as they're only sent (apparently) when the server's buffers get full. But the syn backlog doesn't appear to be full with only ~250 connections in the SYN_RECV state! Is it possible that the SYN flooding message is a red herring and it's something other than the syn_backlog that's filling up? If anyone has any other tuning options I haven't tried yet I'd be more than happy to try them out, but I'm starting to wonder if the syn_backlog setting isn't being applied properly for some reason.

• What are the limitations of virtual machines?

  - by j-g-faustus

  I'm considering setting up a virtual machine running Windows, with Ubuntu 10.10 as the host OS, for those cases where I have a Windows-only program. I understand that using a VM will lose some performance, but are there other limitations to what the OS in a virtual machine can do compared to "running on bare metal"? For example: Can a VM play games, like Dragon Age Origins or Civilization V? (Possibly with poorer framerates and/or lower resolution, but does it play at all?) Can a VM rip DVD/Blue-ray using AnyDVD or similar Windows program? Can a VM handle new hardware that requires dedicated drivers, but the drivers are only available for the OS running inside the VM? (Ex. graphics card, digital camera, card reader for smart card authentication.) Is it possible to say anything about "general limitations" of VMs, or is this wholly dependent on the specific VM?

• How to get the Three.js import/export scripts into Blender on Ubuntu?

  - by Bane

  I have been working with 3D primitives in Three.js, but now I want to import some models. I plan on using Blender, which I have just downloaded with: sudo apt-get install blender However, I was instructed to put the import/export scripts in the .blender/2.62/scripts/addons folder, but it does not exist! .blender/2.62 does exist, but it only has a config folder. The next thing I did is manually changed the script search path in Blender's preferences from // to my homefolder/scripts, which contained the required io_mesh_threejs folder (which, in turn had the .py scripts inside). I saved the changes, restarted Blender, but still nothing: in the menu there is no mention of Three.js at all! What do I do? It would be great if I knew the installation path for Blender, because maybe I could put those scripts there manually. Where should it be installed? EDIT: these are the scripts I'm talking about, along with the instructions: https://github.com/mrdoob/three.js/tree/master/utils/exporters/blender.

• Where is the encfs volume key stored?

  - by Waldorf

  I am trying to use encfs in reverse mode. I understand that the passphase is used to encrypt a key which is then stored encrypted into the encfs6.xml file. What I do not understand is the following. Create en encrypted virtual fs of a folder by using passphrase A unmount this folder. Delete all contents including the encfs6.xml file If you then try to do the same with another passphrse I would expect that a new encfs6.xml would be created. However I get the following error message: "Error decoding volume key, password incorrect" So I wonder, what volume key is incorrect, I thought it was in the encfs6.xml file ?

• Nagios Woudn't Start, now won't Stop!

  - by Bart B

  I ran an update on a CentOS server running Nagios, after the update, Nagios failed to start. The error in the logs was: Failed to obtain lock on file /var/run/nagios.pid: Permission denied So, I checked and there was no pid file for Nagios in /var/run. I created one and gave it the following permissions: -rwxr--r-- 1 nagios nagios 6 May 31 11:58 nagios.pid Nagios then started and seems to be running normally. The only problem is, it refuses to stop now, so I can't re-start it to add new servers and services to be monitored! When I issue the command "service nagios stop", I get [FAILED], but nothing at all gets outputted to the log, and the service remains up. Any ideas on how I can get the service to stop now? I'm running the RPM version which was installed via yum from the RPMForge repositories. The server is CenotOS 5.5.

• How to force Debian to boot new Kernel?

  - by ThE_-_BliZZarD

  I'm running Debian 6, Debian GNU/Linux, with Linux 2.6.32-5-amd64 under Grub2 ( 1.98+20100804-14+squeeze1) on a remote system (no possibility to view the pre-boot messages). I compiled and installed a new kernel, but I can not get it to boot. What I have done: Installed the packages via: dpkg -i linux-headers-3.5.3.20120914-amd64_3.5.3.20120914-amd64-10.00.Custom_amd64.deb linux-image-3.5.3.20120914-amd64_3.5.3.20120914-amd64-10.00.Custom_amd64.deb This updated the Grub configuration. My /boot/grub/grub.cfg now contains: menuentry 'Debian GNU/Linux, with Linux 3.5.3.20120914-amd64' --class debian --class gnu-linux --class gnu --class os { insmod raid insmod mdraid insmod part_msdos insmod part_msdos insmod ext2 set root='(md0)' search --no-floppy --fs-uuid --set 5a3882a9-c7df-4f6a-9feb-f03e3e37be01 echo 'Loading Linux 3.5.3.20120914-amd64 ...' linux /vmlinuz-3.5.3.20120914-amd64 root=UUID=003242b5-121b-49f3-b32f-1b40aea56eed ro acpi=ht quiet panic=10 echo 'Loading initial ramdisk ...' initrd /initrd.img-3.5.3.20120914-amd64 } menuentry 'Debian GNU/Linux, with Linux 2.6.32-5-amd64' --class debian --class gnu-linux --class gnu --class os { insmod raid insmod mdraid insmod part_msdos insmod part_msdos insmod ext2 set root='(md0)' search --no-floppy --fs-uuid --set 5a3882a9-c7df-4f6a-9feb-f03e3e37be01 echo 'Loading Linux 2.6.32-5-amd64 ...' linux /vmlinuz-2.6.32-5-amd64 root=UUID=003242b5-121b-49f3-b32f-1b40aea56eed ro acpi=ht quiet panic=10 echo 'Loading initial ramdisk ...' initrd /initrd.img-2.6.32-5-amd64 } I used grub-set-default "Debian GNU/Linux, with Linux 2.6.32-5-amd64" to set the old kernel as default and then grub-reboot "Debian GNU/Linux, with Linux 3.5.3.20120914-amd64" to boot into the new kernel once. After update-grub I rebooted the system, but everytime it comes back up with the old kernel (2.6). I tried setting the new one as default (grub-set-default 0, update-grub, reboot) but, still the old one. The Syslogs contain NO hint whatsoever about trying to boot the new kernel - only the old one. Would there be any hints regarding problems with a kernel? Is there a way to enable debug-logging in grub? What am I doing wrong? How can I force the system to boot the new kernel?

• Can I specify PBKDF2 rounds to use with LUKS/dm-crypt?

  - by Naftuli Tzvi Kay

  I have encrypted my root partition with dm-crypt/LUKS/cryptsetup on Ubuntu 12.04. Since it uses PBKDF2: Is it possible, during creation of the encrypted disk, to specify a custom amount of PBKDF2 iterations for key derivation? Is it possible, after the encrypted disk has already been created, to modify the amount of PBKDF2 iterations for key derivation? I'd like to make it a little harder to brute-force :)

• Long connection times from PHP to MySQL on EC2

  - by Erik Giberti

  I'm having an intermittent issue connecting to a database slave with InnoDB. Intermittently I get connections taking longer than 2 seconds. These servers are hosted on Amazon's EC2. The app server is PHP 5.2/Apache running on Ubuntu. The DB slave is running Percona's XtraDB 5.1 on Ubuntu 9.10. It's using an EBS Raid array for the data storage. We already use skip name resolve and bind to address 0.0.0.0. This is a stub of the PHP code that's failing $tmp = mysqli_init(); $start_time = microtime(true); $tmp-options(MYSQLI_OPT_CONNECT_TIMEOUT, 2); $tmp-real_connect($DB_SERVERS[$server]['server'], $DB_SERVERS[$server]['username'], $DB_SERVERS[$server]['password'], $DB_SERVERS[$server]['schema'], $DB_SERVERS[$server]['port']); if(mysqli_connect_errno()){ $timer = microtime(true) - $start_time; mail($errors_to,'DB connection error',$timer); } There's more than 300Mb available on the DB server for new connections and the server is nowhere near the max allowed (60 of 1,200). Loading on both servers is < 2 on 4 core m1.xlarge instances. Some highlights from the mysql config max_connections = 1200 thread_stack = 512K thread_cache_size = 1024 thread_concurrency = 16 innodb-file-per-table innodb_additional_mem_pool_size = 16M innodb_buffer_pool_size = 13G Any help on tracing the source of the slowdown is appreciated. [EDIT] I have been updating the sysctl values for the network but they don't seem to be fixing the problem. I made the following adjustments on both the database and application servers. net.ipv4.tcp_window_scaling = 1 net.ipv4.tcp_sack = 0 net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_fin_timeout = 20 net.ipv4.tcp_keepalive_time = 180 net.ipv4.tcp_max_syn_backlog = 1280 net.ipv4.tcp_synack_retries = 1 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.ipv4.tcp_rmem = 4096 87380 16777216 net.ipv4.tcp_wmem = 4096 87380 16777216 [EDIT] Per jaimieb's suggestion, I added some tracing and captured the following data using time. This server handles about 51 queries/second at this the time of day. The connection error was raised once (at 13:06:36) during the 3 minute window outlined below. Since there was 1 failure and roughly 9,200 successful connections, I think this isn't going to produce anything meaningful in terms of reporting.

We had been running the default value (50) and increased it to 150. We also raised the kernel value /proc/sys/net/core/somaxconn (maximum socket connections) to 256 on both the application and database server from the default 128. We did see some elevation in processor utilization as a result but still received connection timeouts.

• Http to https behavior for visits from Internet Explorer client

  - by Emile

  My website has an SSL cert (example url: https://subdomain.example.com). Under Apache it's set up for both port 80 and port 443. So under the following configuration, anyone who goes to http://subdomain.example.com is sent to https://subdomain.example.com . But for visits from Internet Explorer, the redirect doesn't happen. Instead, http visits get a "Internet Explorer cannot display the web page." with a list of client-side solutions to try. Any ideas on how to fix the config so IE visits have the same behavior as the other browsers (that is, send http to https automatically)? NameVirtualHost *:443 <VirtualHost *:80> DocumentRoot /var/www/somewebroot ServerName subdomain.example.com </VirtualHost> <VirtualHost *:443> DocumentRoot /var/www/somewebroot ServerName subdomain.example.com # SSL CERTS HERE </VirtualHost> *Tested IE8, IE9 beta

• Postfix count relayed messages per user

  - by Martino Dino

  I would like to know if it's possible to count the outgoing (relayed) messages on a per user basis in postfix. I'm managing a small commercial SMTP relay and decided that it would be nice to have a detailed daily report on how much mail a single user have sent (and eventually enforce some limits) possibly in realtime. I've looked almost everywhere and started to think that writing my own milter would be the way to go... Are you aware of anything that already exists for postfix that can count and report relayed mail for authenticated users (a script, milter or whatever)?

• Ubuntu: Multiple NICs, one used only for Wake-On-LAN

  - by jcwx86

  This is similar to some other questions, but I have a specific need which is not covered in the other questions. I have an Ubuntu server (11.10) with two NICs. One is built into the motherboard and the other is a PCI express card. I want to have my server connected to the internet via my NAT router and also have it able to wake from suspend using a Magic Packet (henceforth referred to as Wake-On-LAN, WOL). I can't do this with just one of the NICs because each has an issue - the built-in NIC will crash the system if it is placed under heavy load (typically downloading data), whilst the PCI express NIC will crash the system if it is used for WOL. I have spent some time investigating these individual problems, to no avail. My plan is thus: use the built-in NIC solely for WOL, and use the PCI express card for all other network communication except WOL. Since I send the WOL Magic Packet to a specific MAC address, there is no danger of hitting the wrong NIC, but there is a danger of using the built-in NIC for general network access, overloading it and crashing the system. Both NICs are wired to the same LAN with address space 192.168.0.0/24. The built-in ethernet card is set to have interface name eth1 and the PCI express card is eth0 in Ubuntu's udev persistent rules (so they stay the same upon reboot). I have been trying to set this up with the /etc/network/interfaces file. Here is where I am currently: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.0.3 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.1 auto eth1 iface eth1 inet static address 192.168.0.254 netmask 255.255.255.0 I think by not specifying a gateway for eth1, I prevent it being used for outgoing requests. I don't mind if it can be reached on 192.168.0.254 on the LAN, i.e. via SSH -- it's IP is irrelevant to WOL, which is based on MAC addresses -- I just don't want it to be used to access internet resources. My kernel routing table (from route -n) is Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.0.1 0.0.0.0 UG 100 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 My question is this: Is this sufficient for what I want to achieve? My research has thrown up the idea of using static routing to specify that eth1 should only be used for WOL on the local network, but I'm not sure this is necessary. I have been monitoring the activity of the interfaces using iptraf and it seems like eth0 takes the vast majority of the packets, though I am not sure that this will be consistent based on my configuration. Given that if I mess up the configuration, my system will likely crash, it is important to me to have this set up correctly!

• Set Users as chrooted for sftp, but allow user to login in SSH

  - by Eghes

  I have setup a ssh server on debian 7, to use sftp connection. I chrooted some user, with this config: Match Group sftpusers ChrootDirectory /sftp/%u ForceCommand internal-sftp But if i want login with one of this chrooted users in ssh console, they get logged, but autoclose the connection. In logs I see: Oct 17 13:39:32 xxxxxx sshd[31100]: Accepted password for yyyyyy from zzz.zzz.zzz.zzz port 7855 ssh2 Oct 17 13:39:32 xxxxxx[31100]: pam_unix(sshd:session): session opened for user yyyyyyyyyyyy by (uid=0) Oct 17 13:39:32 d00hyr-ea1 sshd[31100]: pam_unix(sshd:session): session closed for user yyyyyyyyyyyy How can I chroot a user only for sftp, and use it as a normal user for ssh?
