• Can't manage iPod from linux anymore

  - by kemp

  I used to be able to see and manage my iPod with different softwares: Amarok, Rhythmbox, GTKPod. The device is a nano 1st generation 4gb. Currently it mounts regularly and can be accessed from the file system, but I get this in dmesg: [ 1547.617891] scsi 11:0:0:0: Direct-Access Apple iPod 1.62 PQ: 0 ANSI: 0 [ 1547.619103] sd 11:0:0:0: Attached scsi generic sg2 type 0 [ 1547.620478] sd 11:0:0:0: [sdb] Adjusting the sector count from its reported value: 7999488 [ 1547.620494] sd 11:0:0:0: [sdb] 7999487 512-byte hardware sectors: (4.09 GB/3.81 GiB) [ 1547.621718] sd 11:0:0:0: [sdb] Write Protect is off [ 1547.621726] sd 11:0:0:0: [sdb] Mode Sense: 68 00 00 08 [ 1547.621732] sd 11:0:0:0: [sdb] Assuming drive cache: write through [ 1547.623591] sd 11:0:0:0: [sdb] Adjusting the sector count from its reported value: 7999488 [ 1547.624993] sd 11:0:0:0: [sdb] Assuming drive cache: write through [ 1547.625003] sdb: sdb1 sdb2 [ 1547.629686] sd 11:0:0:0: [sdb] Attached SCSI removable disk [ 1548.084026] FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!

I say partially because I can transfer files to the iPod but can't remove or modify them. Also one transfer didn't finish and only 9 out of 16 songs were delivered to the device. All other softwares I tried (GTKPod, Amarok, Songbird) don't even detect it. What can I do to troubleshoot this?

Haven't been using my iPod for a while so I can't say when exactly it stopped working. I'm sure Amarok was still at version 1.X but can't remember when it was. My current system is debian testing fully updated. NOTE: just noticed that if I mount the device manually instead of letting nautilus automount it, I can see it again on GTKPod but still not on Banshee AND it's vanished from Rhythmbox...

• problems mounting an external IDE drive via USB in ubuntu

  - by Roy Rico

  I am having a problem connecting a specific IDE drive to my linux box. It's an old drive which I just want to get about 3 GB of files off of. INFO I am trying to connect a 200GB IDE Maxtor Drive, internally and externally... externally: I am using an self powered USB IDE external drive enclosure which I have used to connect various drives, under ubuntu and windows, in the past. The other posts stated it coudl be a problem I think i may have formatted the /dev/sdc partition instead of /dev/sdc1 partition when i originally formatted the drive. internally: I only have one machine left that has an internal IDE interface, and it's got XP on it. I plugged this drive internally into this machine with windows XP and used the ext2/ext3 drivers to mount this drive, but some files have question marks (?) in the file names which is messing up my copy process in windows. I can't delete the files under windows. Ubuntu Linux will not install on my only remaining machine that has IDE controller. I have tried the suggestions in the questions below http://superuser.com/questions/88182/mount-an-external-drive-in-ubuntu http://superuser.com/questions/23210/ubuntu-fails-to-mount-usb-drive it looks like i can see the drive in /proc/partitions $ cat /proc/partitions major minor #blocks name 8 0 78125000 sda 8 1 74894998 sda1 8 2 1 sda2 8 5 3229033 sda5 8 16 199148544 sdb <-- could be my drive? but it's not listed under fdisk -l $ fdisk -l Disk /dev/sda: 80.0 GB, 80000000000 bytes 255 heads, 63 sectors/track, 9726 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xd0f4738c Device Boot Start End Blocks Id System /dev/sda1 * 1 9324 74894998+ 83 Linux /dev/sda2 9325 9726 3229065 5 Extended /dev/sda5 9325 9726 3229033+ 82 Linux swap / Solaris and here is my log of /var/log/messages. with a bunch of weird output, can someone let me know what that weird output is?

• OpenVPN Clients using server's connection (with no default gateway)

  - by Branden Martin

  I wanted an OpenVPN server so that I could create a private VPN network for staff to connect to the server. However, not as planned, when clients connect to the VPN, it's using the VPN's internet connection (ex: when going to whatsmyip.com, it's that of the server and not the clients home connection). server.conf local <serverip> port 1194 proto udp dev tun ca ca.crt cert x.crt key x.key dh dh1024.pem server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt client-to-client keepalive 10 120 comp-lzo persist-key persist-tun status openvpn-status.log verb 9 client.conf client dev tun proto udp remote <srever> 1194 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert x.crt key x.key ns-cert-type server comp-lzo verb 3 Server's route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.8.0.2 * 255.255.255.255 UH 0 0 0 tun0 10.8.0.0 10.8.0.2 255.255.255.0 UG 0 0 0 tun0 69.64.48.0 * 255.255.252.0 U 0 0 0 eth0 default static-ip-69-64 0.0.0.0 UG 0 0 0 eth0 default static-ip-69-64 0.0.0.0 UG 0 0 0 eth0 default static-ip-69-64 0.0.0.0 UG 0 0 0 eth0 Server's IP Tables Chain INPUT (policy ACCEPT) target prot opt source destination fail2ban-proftpd tcp -- anywhere anywhere multiport dports ftp,ftp-data,ftps,ftps-data fail2ban-ssh tcp -- anywhere anywhere multiport dports ssh ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:20000 ACCEPT tcp -- anywhere anywhere tcp dpt:webmin ACCEPT tcp -- anywhere anywhere tcp dpt:https ACCEPT tcp -- anywhere anywhere tcp dpt:www ACCEPT tcp -- anywhere anywhere tcp dpt:imaps ACCEPT tcp -- anywhere anywhere tcp dpt:imap2 ACCEPT tcp -- anywhere anywhere tcp dpt:pop3s ACCEPT tcp -- anywhere anywhere tcp dpt:pop3 ACCEPT tcp -- anywhere anywhere tcp dpt:ftp-data ACCEPT tcp -- anywhere anywhere tcp dpt:ftp ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:smtp ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT all -- anywhere anywhere Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT all -- 10.8.0.0/24 anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain fail2ban-proftpd (1 references) target prot opt source destination RETURN all -- anywhere anywhere Chain fail2ban-ssh (1 references) target prot opt source destination RETURN all -- anywhere anywhere My goal is that clients can only talk to the server and other clients that are connected.

• Priority of an application

  - by Burkhard

  Hello, I asked a question about the priority in Windows XP here. I got one answer and it apparently does not work. The question is: is the priority shown in the Task-Manager always the real priority? Or can there be a difference? Edit: With the installation of the service pack 3 of WinXP, it shows the expected priority in the task manager.

• my multi boot can't boot to XP 'resumeobject' is missing

  - by GwenKillerby

  In my multi boot set up, booting to vista and 7 goes fine, but when I try to boot to XP, i get an error Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1. Insert your Windows installation disc and restart your computer. 2. Choose your language settings, and then click "Next." 3. Click "Repair your computer." If you do not have this disc, contact your system administrator or computer manufacturer for assistance. File: \NTLDR Status: 0xc000000e Info: The selected entry could not be loaded because the application is missing or corrupt. See below. Clearly the resumeobject seems to be missing in the XP entry ("Real Mode Boot sector"), only I don't know how to restore it. Vista is on **C:**, Win7 is on **F:** (as is the bootmgr ??? ) and WinXP is on **E:** What I've tried: [1] I've used about 5 windows discs, that is the Recovery Consoles from real XP install CD's and 3 virtual Recovery Consoles. All failed. The real CD's work ONE time, but won't let me finish, I only got as far as [b]fixboot E:[/b] Then they shut the laptop down, I kid you not. On a next startup, all 5 CD's ask me for some Admin password that I've never added! [2] I have VisualBCD and EasyBCD, but the most obvious things I tried there didn't solve the problem. So know I don't exactly know what to do with them. [3] I CAN boot into XP with the FIX NTLDR workaround of http://milescomer.com/tinyempire.com/notes/ntldrismissing.htm, but it doesn't fix it permanently QUESTION: How do I fix it permanently? bcdedit /enum output: Windows Boot Manager -------------------- identifier {bootmgr} device partition=F: path \bootmgr description Windows Boot Manager locale en-US default {current} displayorder {current} {812e27a9-27b7-11e4-8fb4-dfa8174ae8dc} {812e27ac-27b7-11e4-8fb4-dfa8174ae8dc} timeout 30 resume No Windows Boot Loader ------------------- identifier {current} device partition=C: path \Windows\system32\winload.exe description Vista locale nl-NL osdevice partition=C: systemroot \Windows resumeobject {73d8b5bc-2764-11e4-b181-806e6f6e6963} Windows Boot Loader ------------------- identifier {812e27a9-27b7-11e4-8fb4-dfa8174ae8dc} device partition=F: path \Windows\system32\winload.exe description Daisy Etta locale en-US osdevice partition=F: systemroot \Windows resumeobject {b8c234a4-27b0-11e4-b8b3-806e6f6e6963} Real-mode Boot Sector --------------------- identifier {812e27ac-27b7-11e4-8fb4-dfa8174ae8dc} device partition=E: path \NTLDR description XP Thank you.

• Multiple subnets on isc-dhcp-server using ddns with bind9

  - by legioxi

  On my network I have two subnets: 10.100.1.0/24 - Wired/wireless 10.100.7.0/24 - VPN Both subnets are served by isc-dhcp-server running on a Debian VM. This same VM runs bind9 for my DNS. ISC-DHCP-SERVER is configured to use DDNS and update BIND9 with hosts/IPs. Everything runs great until a device drops off the wired/wireless network and pops onto the VPN. When connecting on the VPN, a DHCP lease is handed out on the new subnet but DDNS does not update BIND9. Since the device has A/TXT/PTR records it appears ISC-DHCP-SERVER won't switch them to the new IP. The logs show: Connect to wireless: Nov 6 20:55:13 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': adding an RR at 'demo-iphone.internal.mydomain.com' A Nov 6 20:55:13 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': adding an RR at 'demo-iphone.internal.mydomain.com' TXT Nov 6 20:55:13 core-server dhcpd: DHCPACK on 10.100.1.160 to FF:FF:FF:FF:FF:FF (demo-iphone) via eth0 Nov 6 20:55:13 core-server dhcpd: Added new forward map from demo-iphone.internal.mydomain.com to 10.100.1.160 Nov 6 20:55:13 core-server dhcpd: Added reverse map from 160.49.21.172.in-addr.arpa. to demo-iphone.internal.mydomain.com Switch to VPN: Nov 6 20:56:34 core-server dhcpd: DHCPOFFER on 10.100.7.101 to BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': update unsuccessful: demo-iphone.internal.mydomain.com: 'name not in use' prerequisite not satisfied (YXDOMAIN) Nov 6 20:56:34 core-server dhcpd: DHCPREQUEST for 10.100.7.101 (10.100.1.2) from BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server dhcpd: DHCPACK on 10.100.7.101 to BB:BB:BB:BB:BB:BB (demo-iphone) via 10.100.7.0 Nov 6 20:56:34 core-server named[2417]: client 127.0.0.1#57697: updating zone 'internal.mydomain.com/IN': update unsuccessful: demo-iphone.internal.mydomain.com/TXT: 'RRset exists (value dependent)' prerequisite not satisfied (NXRRSET) Nov 6 20:56:34 core-server dhcpd: Forward map from demo-iphone.internal.mydomain.com to 10.100.7.101 FAILED: Has an address record but no DHCID, not mine. One thing to note is that the MAC of the device when connecting via VPN is the MAC of my Cisco ASA5512X and not the actual device. The ASA is relaying the DHCP request from the VPN client to the VM running ISC-DHCP-SERVER. Is there a way to get DDNS working in this scenario?

• Configuring Fortigate OS4 for FTPS

  - by Paul

  I configured iis7 ftp to allow ssl connections. I set the ssl firewall to use ports 50000-50050. If I set up a custom service on my fortigate firewall for ftps with source ports 990-50050 and destination ports 990-50050, set it to a firewall policy and connect from a client it connects and works successfully. If I create a service FTPS Control with source port 990 and destination port 990 and another service,FTP Data with source ports 50000-50050 and destination ports 50000-50050 add them to a group FTPSSL, replace the ftps policy with FTPSSL and try connecting it tries to connect to port 990 and eventually times out. Is there a way to configure the service to only use the ports I need and not every port from 990 up?

• Dynamips and Tap Devices, To and From the same machine

  - by Kyle Brandt

  I am setting up a dynamips/dynagen lab and am wondering if there is any way to get traffic to route out one tap devices, go into the lab, and come back to a tap device on the same machine. I have tried host specific routes as well as removing the route created when I give the tun device an ip via ifconfig. With both of these, traffic always preferes the attached devices and won't go through my lab. Any way to make this work without a separate machine or vm?

• Linux disk IO load breakdown, by filesystem path and/or process?

  - by Ryan B. Lynch

  Does anyone have experience with a tool that can provide an indication of disk IO load by filesystem path. I use to 'iostat' utility, frequently, to learn how much disk activity is taking place on a Linux host. 'iostat' provides a per-device breakdown, so you can see activity on a particular block device. But it doesn't go any deeper than that--you can't, for instance, query the write load generated by 'httpd' in the directory '/var/log/httpd/'.

• Stop squid caching 302 and 307 with deny_info

  - by 0xception

  TLDR: 302, 307 and Error pages are being cached. Need to force a refresh of the content. Long version: I've setup a very minimal squid instance running on a gateway which shouldn't not cache ANYTHING but needs to be solely used as a domain based web filter. I'm using another application which redirects un-authenticated users to the proxy which then uses the deny_info option redirects any non-whitelisted request to the login page. After the user has authenticated the firewall rule gets placed so they no longer get sent to the proxy. The problem is that when a user hits a website (xkcd.com) they are unauthenticated so they get redirected via the firewall: iptables -A unknown-user -t nat -p tcp --dport 80 -j REDIRECT --to-port 39135 to the proxy at this point squid redirects the user to the login page using a 302 (i've also tried 307, and i've also make sure the headers are set to no-cache and/or no-store for Cache-Control and Pragma). Then when the user logs into the system they get firewall rule which no longer directs them to the squid proxy. But if they go to xkcd.com again they will have the original redirection page cached and will once again get the login page. Any idea how to force these redirects to NOT be cached by the browser? Perhaps this is a problem w/ the browsers and not squid, but not sure how to get around it. Full squid config below. # # Recommended minimum configuration: # acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 acl localnet src 192.168.182.0/23 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl https port 443 acl http port 80 acl CONNECT method CONNECT # # Disable Cache # cache deny all via off negative_ttl 0 seconds refresh_all_ims on #error_default_language en # Allow manager access only from localhost http_access allow manager localhost http_access deny manager # Deny access to anything other then http http_access deny !http # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !https visible_hostname gate.ovatn.net # Disable memory pooling memory_pools off # Never use neigh cache objects for cgi-bin scripts hierarchy_stoplist cgi-bin ? # # URL rewrite Test Settings # #acl whitelist dstdomain "/etc/squid/domains-pre.lst" #url_rewrite_program /usr/lib/squid/redirector #url_rewrite_access allow !whitelist #url_rewrite_children 5 startup=0 idle=1 concurrency=0 #http_access allow all # # Deny Info Error Test # acl whitelist dstdomain "/etc/squid/domains-pre.lst" deny_info http://login.domain.com/ whitelist #deny_info ERR_ACCESS_DENIED whitelist http_access deny !whitelist http_access allow whitelist http_port 39135 transparent ## Debug Values access_log /var/log/squid/access-pre.log cache_log /var/log/squid/cache-pre.log # Production Values #access_log /dev/null #cache_log /dev/null # Set PID file pid_filename /var/run/gatekeeper-pre.pid SOLUTION: I believe I might have found a solution to this. After days and days trying to figure it out, only through a random stumble I found client_persistent_connections off server_persistent_connections off This did the trick. So it wasn't so much cache as it was a single persistent connection messing things up. W000T!

• Open ports broken from internal network

  - by ksvi

  Quick summary: Forwarded port works from the outside world, but from the internal network using the external IP the connection is refused. This is a simplified situation to make the explanation easier: I have a computer that is running a service on port 12345. This computer has an internal IP 192.168.1.100 and is connected directly to a modem/router which has internal IP 192.168.1.1 and external (public, static) IP 1.2.3.4. (The router is TP-LINK TD-w8960N) I have set up port forwarding (virtual server) at port 12345 to go to port 12345 at 192.168.1.100. If I run telnet 192.168.1.100 12345 from the same computer everything works. But running telnet 1.2.3.4 12345 says connection refused. If I do this on another computer (on the same internal network, connected to the router) the same thing happens. This would seem like the port forwarding is not working. However... If I run a online port checking service on my external IP and the service port it says the port is open and I can see the remote server connecting and immediately closing connection. And using another computer that is connected to the internet using a mobile connection I can also use telnet 1.2.3.4 12345 and I get a working connection. So the port forwarding seems to be working, however using external IP from the internal network doesn't. I have no idea what can be causing this, since another setup very much like this (different router) works for me. I can access a service running on a server from inside the network both through the internal and external IP. Note: I know I could just use the internal IP inside of the network to access this service. But if I have a laptop that must be able to do this both from inside and outside it would be annoying to constantly switch between 1.2.3.4 and 192.168.1.100 in the software configuration.

• No option to connect to wireless network

  - by Casebash

  I don't have any option to connect to wireless. It just doesn't appear in the taskbar at all - even the no wireless networks were found doesn't appear. In network connections, I only have the option of using a wired connection. According to device manager, I have a working VIA Rhine II Fast Ethernet Adapter (this device only appeared after I selected showing hidden devices). I have already attempted restarting the computer a few times. Does anyone have any suggestions?

• Does extra hard drive cache make a difference for streaming video?

  - by johnny

  I am looking at the following two drives for a RAID device, which will be streaming normal things but also a lot of video: Seagate Constellation ES.3 ST4000NM0033 - hard drive - 4 TB - SATA-600 TOSHIBA DT01ACA300 3TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Will the 128 MB cache on the Seagate have an effect in my described scenario, compared to the 64 MB on the Toshiba? If so, what sort of difference can I expect? I'm using a qnap device, if that matters.

• How much of slow and fast flash memory a "flash memory" have?

  - by gsc-frank

  Trying to know what is the best of my flash memories to use ReadyBoost I realize that I don't know how much of fast flash memory each of my flash drives have. One can read: In some situations, you might not be able to use all of the memory on your device to speed up your computer. For example, some flash memory devices contain both slow and fast flash memory, but ReadyBoost can only use fast flash memory to speed up your computer.

• Set certain WSUS updates to auto-install

  - by Nicolas

  We're running a WSUS server for the simple purpose of caching updates. Since we are a very small network of all "power users", we've got the domain group policy for WSUS updates on the clients set to prompt for download/install. i.e. We don't want updates to install without our knowledge. But there are a few cases where it would be nice to be able to set a certain update to auto-install. e.g. Windows Defender updates, Malicious Software Removal Tool, Outlook Junk Email Filter, etc. Basically all the silly little updates that you would always install anyway and don't require a restart. Is there a way to set the general policy to prompt for download/install, but auto-install certain regular updates? P.S. WSUS itself does have the facility to auto-approve certain updates. That part works. Facts & Figures: SBS 2003 domain Windows 7 Pro clients Windows XP Pro clients

• HID USB Very Strange Problem...

  - by Lasanha

  I realy hope some one can help me here cause i search all over the web and nothing comes up.. I allways used PS/2 KB and Mouse and a USB KeyPad (Genius ErgoMedia 500 Gaming Explorer) to play some games, mmorpg, fps, you named, very good whit 11 keys whit possible macros etc etc... Now it comes the problem, i have a USB mouse that have 4 extra buttons, and i need more button, i love buttons.. Well, i plug in the USB mouse and disconectes de PS/2. Everything is ok until i toutch the mouse. If i do so, the ErgoMedia goes off, then on, then i mouse the mouse or press a button and all over again. Yesterday i went buying a new mouse that i liked, a USB mouse too (NPlay whit macros and all that stuff 3600dpi...) Hoping the problem was only whit the other mouse, but no.. It does the exact same thing, ErgoMedia keeps disconecting and conecting everytime i toutch the mouse. What i allready did: Update drivers of both mouses Update drivers of ErgoMedia (no specific drivers(Windows based)) Update drivers of MB Chipset (Actualy no, cause it was up to date allready) Trying other USB Ports (4 Ports back, 4 Ports Front and even 1 Port in 16 card slot device) Disable the "Allows Windows to shut down the energy bla bla" thing in Device Setings. Look up in the Device Setings only apear a problem on the ergomedia (Human interface Device) when i move the damm mouse.. Using Everest to read behavier, everything normal, exepts the disconecting thing, but no errors. Not a power suply, only the ErgoMedia and the mouse are in the USBs, and i allready disable the 16 card reader whit one usb slot to see.. Clean the IRQ registry. Look the entire internet for a fix solution. Help others problems wile looking for a fix for me (Im not a pro but not a completly stupid) Talking to you beggin you to help me as a last resorce... Machine: Acer M3641 Core2Quad 64x Based OS Vista 64b 4GbRAM HD Audio and Graphics I realy hope some one out there knows a fix for this, maybe it´s a simple thing, so simple that i´m to stupid to see that.. Sorry for my bad inglish but i write lot of erros even in my language. Any help will be very welcome. Tanks for ur concern and atention ^^

• Ubuntu 12.04 boot degraded raid

  - by beacon_bonanza

  I've installed Ubuntu 12.04.1 in a new server and set up the 4 hard drives with 3 RAID 1 devices, the configuration is such that the first two drives have md0 (swap space) and md1 (/) with the third and fourth drives having md2 (/var). I've been testing the operation under a drive failure and found that the system boots fine if I remove disk two but if I remove disk one then the system gets to grub and then just restarts. I'm confused as to why grub appears to be loading properly from disk two but then the boot fails. I've tried to copy the MBR from disk 1 to 2: dd if=/dev/sda of=/dev/sdb bs=512 count=1 but this didn't make a difference.

• Simple Image Capture Tool for Mac OS X that uses FireWire

Anyway, Image Capture does not recognize the firewire video feed as an image capture device. What software would give me the simplest "capture this frame from live firewire video feed to image" functionality.

• How do I enable SELinux when booting a ramdisk from a CD/DVD?

  - by JeffG

  I have a bootable DVD which boots the same Kernel as the Hard Drive (which uses SELinux). I have copied /etc/selinux and all kernel modules to my ramdisk, and have tried various combinations of selinux=1 and selinux 1 with enforcing 1 and enforcing 0. as Kernel boot parameters. All files contained in the checkpolicy, libselinux, policycoreutils, selinux-policy and selinux-policy-targeted rpms have also been copied into the ramdisk tree. After the system boots from the ramdisk, I check dmesg: % dmesg | grep -i selinux Kernel command line: initrd=idrd.img ramdisk_size=110476 selinux=1 SELinux: Initializing. SELinux: Starting in permissive mode selinux_register_security: Registering secondary module capability SElinux: Registering netfilter hooks But SELinux isn't running: % /usr/sbin/getenforce Disabled % /usr/sbin/setenforce 1 /usr/sbin/setenforce: SELinux is disabled Neither /var/log/messages nor /proc/kmsg hold clues.

• Is there any USB2.0 data transfer chunk size limit?

  - by goldenmean

  With one read() or write() at a time, can we increase the bulk data size over USB interface? For example, I want to transfer chunk of 1024 (1K) bytes data and if the device has limitations of only 64bytes, is there any way I can increase the packet size for read() and write() system call over USB? Is there any limitation on size of data transfer over USB in a host-device environment?
