Your example could be considered a useless use of cat, because you could have used the redirection instead. However, if the _actual_ program you're running, fossil, has an option for a verbose output or progress indicator, I would suggest using this (maybe man fossil lists something like -v). There are also tools that act on SIGINT or SIGINFO. This signal can be sent by pressing Ctrl-T. Maybe fossil also outputs a status message? Offering a percentage of how much of a file has been read would imply knowledge about the size of the file. The construct cat | fossil does not provide fossil with that information or even the file name in question. But obtaining the amount of data processed should be possible somehow.

That assumption, as someone who ran a hosting organisation since 1993, is rude (some might say bad, but I would say rude). Web browsers/clients that don't support SNI are screwed -- they'll receive a certificate validation failure error. Internet Explorer 6.x through 8.x -- newer is not available on Windows XP -- do not support SNI (this is even mentioned in the above Wikipedia page). They return the error There is a problem with this website's security certificate due to lack of SNI support. Let me be clear: THIS IS NOT THE FAULT (OR AGE) OF THE OS. THIS HAS TO DO WITH THE WEB BROWSER. Why? Because Firefox 19.0 on Windows XP works just fine, as it supports SNI. AFAIR the problem is that some crypto library on Windows XP does not support SNI. IE uses it, Firefox and others probably don't. So how do you solve this problem for legacy clients? Simple: By dedicating an IP address to the SSL-based virtualhost/webserver (i.e. one IP address per SSL-based virtual host), and do away with name-based vhosting for SSL. That's the only way. I agree that SNI is suboptimal, unfortunately it was the best of bad solutions: - We just don't have enough IPv4 addresses to dedicate one per virtual hostname. - We could use IPv6 only which means excluding even more legacy clients. - Bundling all sites under www.freebsd.org creates problems with cookies, more pain in configuration, and less flexibility in moving things around. - Using SubjectAlternatName (SAN) certificates where strongly considered, but fewer CA's support them (most have no clue) and it becomes a lot more painful to add new hosts.

FreeBSD 9 and Windows XP
Good afternoon, FreeBSD enthusiasts. Can FreeBSD 9.1 be installed on a computer on which Windows XP currently resides? If so, how can this installation be done? In particular, is there a way to install 9.1 so that it can be booted from the traditional master boot record? It is important that, when I am done, I can still boot to Windows XP, as I must run some applications not available on FreeBSD. If the idea I am proposing is not feasible with version 9.1, will it work with 8.3? Any comments are appreciated. If this question has already been asked many times before, please just let me know where to look to find the answer. Thanks.

That's why I could not use it on my server with 1TB UFS2. Did this improve in the last year? (I guess my experience is from the time around 9.0 release).

No. Subversion is a large system, with a ton of dependencies, and there's basically _nothing_ to gain by having to spend extra effort trying to keep an imported version up to date. Having svn-X.0 in the source tree, imported at great expense of time and effort, will provide exactly _zero_ benefits if the underlying format of the repository changes (like subversion likes doing really often). On the other hand, installing subversion from the ports or even from the precompiled packages is always going to work, and we're always going to have a port for it as long as it's a tool that's required to work with the source tree of the system. Is the new pkg system going to totally replace the pkg_ system in the base 9.2-Release? I think so.

If no : Return an error and gracefully stop your program instead of a crash which will loose data . It's a fortran program. I'm not very stong in C. Ideally I'd just use the OS (shell) means, but I need to understand better which resourse limit controls what. For example, with sh limits(1), I see: $ limits Resource limits (current): cputime infinity secs filesize infinity kB datasize 524168 kB stacksize 524168 kB coredumpsize infinity kB memoryuseinfinity kB memorylocked 64 kB maxprocesses12200 openfiles 117594 sbsize infinity bytes vmemoryuse infinity kB pseudo-terminals infinity swapuse infinity kB $ Which of these are relevant to my case? Finally, the actual problem is on linux, but I hope if I'm able to understand how things work on FreeBSD, then I could do it on linux too, especially if it's just a sh command. Thanks Anton It is not necessary to know C for the above steps . If you have source and if it is compilable by Fortran 90 or later standard , it may use allocation . ( Please see ALLOCATABLE , ALLOCATE , DEALLOCATE in a Fortran = 90 manual ). I am compiling Fortran 77 programs with respect to 2003 standart by specifying lines as fixed by G95 which it is available in FreeBSD also ( www.g95.org ) . It may be necessary to convert Hollerith format specifiers to apostrophes . Personally I do not any idea about the above parameters . You may use System Monitor or top to see memory usage . If there is no sufficient memory , you may not start your program , or it starts to swap you may kill suitable programs , etc. . Thank you very much .

vlan routing
I am trying set this up. First I munged the IP addresses. Not to worry if I hit yours. I did the following commands: ifconfig vlan0 create ifconfig vlan0 vlan 95 vlandev fxp0 ifconfig vlan0 inet 134.217.128.117 netmask 255.255.255.0 ifconfig fxp0 add 134.217.128.117 netmask 255.255.255.0 route add -inet 134.217.128.117 134.217.128.1 ifconfig shows: fxp0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu 1500 options=8VLAN_MTU ether 00:d0:b7:56:cf:ab inet 45.22.17.3 netmask 0xfc00 broadcast 45.22.19.255 inet 45.22.17.17 netmask 0x broadcast 45.22.17.17 inet 134.217.128.117 netmask 0xff00 broadcast 134.217.128.255 media: Ethernet autoselect (100baseTX full-duplex) status: active bge0: flags=8802BROADCAST,SIMPLEX,MULTICAST metric 0 mtu 1500 options=9bRXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM ether 00:09:5b:60:e4:1f media: Ethernet autoselect (none) status: no carrier vlan0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu 1500 ether 00:d0:b7:56:cf:ab inet 134.217.128.117 netmask 0xff00 broadcast 134.217.128.255 media: Ethernet autoselect (100baseTX full-duplex) status: active vlan: 95 parent interface: fxp0 Needless to say it does not work.

I also tried booting the system with IP of 134.217.128.117 but I did not get the rc.conf macros correctly. I do know I can not route through the switch without going the vlan commands. _ Douglas Denault http://www.safeport.com d...@safeport.com Voice: 301-217-9220 Fax: 301-217-9277 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: How to know % of read file in cat?
You might want to try the sysutils/pv port, which is a small program that works like cat, but provides a progress bar.

periodic security always sends output mail
I would like to configure periodic on my FreeBSD servers to only send daily/weekly/monthly/security mails (or logs) when there is something important to report. I'm close, but periodic security seems to _always_ send mail, even when there is nothing to report. My periodic.conf.local has these pertinent lines (ignore weekly and monthly for now): daily_show_success=NO security_show_success=NO daily_show_info=NO security_show_info=NO This has the desired effect on daily -- no mail unless something has happened. And it _almost_ works for security, but it still sends a nearly-empty report with only this: Security check: -- End of daily output -- That behavior is the same whether security is a separate report or included into daily using daily_status_security_inline=YES. I think the reason is /etc/periodic/daily/450.status-security sets rc=3 after running 'periodic security', and so there's no way to mask the output. Is there some other (preferably supported) means of achieving the goal of no mail or log unless there's something to report?

If i understand your task correctly, then this line is faulty from your configuration: ifconfig fxp0 add 134.217.128.117 netmask 255.255.255.0 You don't need it. route add -inet 134.217.128.117 134.217.128.1 This is smth absoulutely wrong:) Basically, if you only need a vlan interface that could be used for routing, you need these commands only: ifconfig vlan95 create ifconfig vlan95 inet 134.217.128.117/24 vlan 95 vlandev fxp0 and in /etc/rc.conf you should put such strings: cloned_interfaces=vlan95 ifconfig_vlan95=inet 134.217.128.117/24 vlan 95 vlandev fxp0 for the interface to be created on reboot.
