If I execute these via command line, will they persist after a reboot? Or, should I be putting these into a file like /etc/sysctl.conf? --------------snip-------------- /sbin/sysctl -w net.ipv4.tcp_max_syn_backlog=2048 /sbin/sysctl -w net.ipv4.tcp_fin_timeout=30 /sbin/sysctl -w net.ipv4.tcp_keepalive_intvl=10 /sbin/sysctl -w net.ipv4.tcp_keepalive_probes=7 /sbin/sysctl -w

I get these errors from the following settings in /etc/sysctl.conf file: # Custom Settings: net.ipv4.tcp_max_syn_backlog=2048 net.ipv4.tcp_fin_timeout=30 net.ipv4.tcp_keepalive_intvl=10 net.ipv4.tcp_keepalive_probes=7 net.ipv4.tcp_keepalive_time=1800 net.ipv4.tcp_max_tw_buckets=360000 net.ipv4.tcp_synack_retries=3 net.ipv4.tcp_rmem="4096 87380 16777216" net.ipv4.tcp_wmem="4096

Hi, I'm writing to you on behalf of the Pasteur Institute's (Paris, France) IT team. We're currently using dovecot-0.99.10.5_2 on a FreeBSD 5.3. We're planning to upgrade to dovecot-1.x with an openLDAP user and password database and patch it at the same time to include some authentication feature we're using : Since most of our user currently don't use dovecot at all and

See tcp_xmit() in gpxe/src/net/tcp.c: Actually syslinux.efi seems to be using the implementation calling into UEFI via these functions: http://git.kernel.org/cgit/boot/syslinux/syslinux.git/tree/efi/tcp.c I've tried to add debug messages to these

I'm using OpenSSH_3.5p1 (server protocol 2.0 ) on a Compaq device V5.1A with C2 Security (SIA) configured. I must set UsePrivilegeSeparation to no to get this working.

I run Samba server on my OpenWRT router. I normally access the share as guest from my Linux box. Here's the relevant line from my /etc/fstab: //192.168.1.1/T_Drive /mnt/r cifs guest,rw,iocharset=utf8,uid=1000 0 0 Recently I harnessed rsync to backup a number of photos from the Linux to the Samba share mountpoint but rsync said that chgrp failed when it tried to change group

Hello, I'm trying to find out how to pxe boot with syslinux.efi on QEMU with OVMF. After getting through the initial hurdle caused by the iPXE based option ROM included with QEMU having a problem as described in these threads: http://www.syslinux.org/archives/2014-November/022804.html http://sourceforge.net/p/edk2/mailman/message/33236100/ I'm now getting further to almost being able

When -fstack-protector is turned on, linker fails to find the symbol "__stack_chk_guard" because at least for powerpc64le, glibc doesn't provide this symbol. Instead, they put the stack guard into TCB. x86 fixed this issue by injecting a special address space (which is later translated to TCB register access) and hard code the offset of stack_guard, but I don't see a easy way to

I'll come up with a address-space-based proof of concept.

I found a bit weird to use address space for this, since the offset of getting stack_guard in TCB is, unfortunately, negative: https://github.com/gcc-mirror/gcc/blob/master/gcc/config/rs6000/linux64.h#L610 In my understanding an address space is referring to a segment register (-on powerpc 32bit; or SLB entry on powerpc 64bit?) with a non-negative offset value, so that it's actually accessing

Hi, an updated and more civilized post (to my one and only previous one) on getting OpenSSH to work on HP-UX 11 using the TCB. I used the HP ANSI C compiler. Firstly, I needed to download, compile and install OpenSSL, EGD and ZLib. Specific issues: configure did not handle hpux 11 login.c did not compile makefile did not use $(CFLAGS) sshd did not compile (pam issues), I wanted to use
