Need some help here.
by Vidhata Deshpande 12 Aug '03

Hello Devdas.... Thanks for the help... but I want to check the exit code.... How can I access the exit code and assign the exit code value to a variable. I tried using the command var=`ping -c1 -w3 202.54.1.30` echo $var This still outputs the regulr ping output | if my eth crd is down...it still o/p's "connect : Network is unreachable" directly to the monitor,without assigning the Exit Code value to the variable.

Sendmail configuration problem
by Abhijeet More 12 Aug '03

12 Aug '03

Hi there, I've been trying to configure sendmail on my office box. (version 8.12 on Debian 3.0 Woody) I would be using the office smtp router as the smarthost. I need to configure my daemon to authenticate (AUTH = LOGIN) to this smarthost before trying to send mail. I have checked out the procedure using the telnet to port 25. It sure works. Now to configure sendmail for this we have two options: DefaultAuthInfo ( and provide the mapping in the file thats the argument of DefaultAuthInfo) or The 'authinfo' ruleset : This can be done by using FEATURE('authinfo') and providing the mapping. The problem: 1.> I could not find the exact syntax for mapping the auth using DefaultAuthInfo. Yes, I have checked the documentation. It seems that this option is deprecated and would not be supported in the future versions. 2.> So I went on and used FEATURE('authinfo') and provided the mapping in the appropriate file ( The syntax is documented for this) 3.> However what happens is that, even though sendmail correctly tries to use the smarthost for delivering all non - local mail, it does not try to AUTH before the MAIL FROM: ! I checked this using the '-X' option. It returns the non - local mail to me saying it gave a 505 - Authentication required error. Incidentally, I had even tried to configure exim before this for the same situation. Even after making all the required configurations for exim, it would not AUTH itself to the smarthost. I have tried to be lucid enough and hope to have explained the problem clearly. Has anyone out here experienced this before. If so what's the way out? ciao Abhijeet More Here's my sendmail.mc file (generated using the sendmailconfig program) but I have removed the comments. divert(0)dnl define(`_USE_ETC_MAIL_')dnl include(`/usr/share/sendmail/cf/m4/cf.m4')dnl VERSIONID(`$Id: sendmail.mc, v 8.12.3-4 2002-04-15 17:35:56 cowboy Exp $') OSTYPE(`debian')dnl DOMAIN(`debian-mta')dnl LOCAL_CONFIG define(`SMART_HOST', `10.6.12.207')dnl FEATURE(`nocanonify')dnl FEATURE(`accept_unresolvable_domains')dnl FEATURE(`local_no_masquerade')dnl FEATURE(`authinfo')dnl LOCAL_CONFIG Cwmymachine.world.com FEATURE(`use_cw_file')dnl FEATURE(`use_ct_file')dnl FEATURE(`nouucp', `reject')dnl HACK(`nodns')dnl FEATURE(`smrsh')dnl define(`confME_TOO', True)dnl define(`confTO_QUEUEWARN', `1h')dnl define(`confTO_QUEUERETURN', `1d')dnl include(`/etc/mail/dialup.m4')dnl include(`/etc/mail/provider.m4')dnl MAILER_DEFINITIONS MAILER(local)dnl MAILER(smtp)dnl ^^^^^^^^^^^^^^^^^^^^End of sendmail.mc file

YANB-(yet another newbie)
by Netbaba 12 Aug '03

I traditionally try out linux for short bursts of time and get sick of it or it stops dual booting and go back to m$ for day to day work. I wanted to install redhat 8.0 from PCQ with win 2000 pro Is PCQ 8.0 different from redhat or only change is with the name and some instyallation options. How can I do that? What partition schemes to use for a 20 Gb? Is grub better than LILO ? How do I ensure in case of a booting problem my data in NTFS or FAT partitions are intact and easily recoverable ? I know regular back up helps but That may be too much at times. Will ge force nivada card and Proview LCD monitor be supported and what's the settings I need to use?

ISR called reentrantly
by Harshul Nayak (ealcatraz) 11 Aug '03

11 Aug '03

Hello all, one of the servers which is under my administration is a Linux box with dual processor, currently running redhat 7.3 while checking through the logs (/var/log/messages) found out this error Jul 31 19:03:46 XXXXX kernel: ISR called reentrantly!! Jul 31 19:26:55 XXXXX kernel: ISR called reentrantly!! Jul 31 22:27:50 XXXXX kernel: ISR called reentrantly!! The server is running a webserver and a mailinglist server When interacting with the hosting company they said it is BIOS issue , hence we updated the BIOS. then upgraded the kernel. Kernel Upgrade: ============ Latest linux kernel version: (as of 10/08/203) Linux version 2.4.20-19.7smp Old linux kernel version (when the error did occurred) ================== Linux version 2.4.18-24.7.xsmp Now I wanted to knw how the error message shown above and the BOIS was related. Can someone throw some light in the right direction, I do understand that the hardware and the kernel as closely related... Is there more proper explanation of the relationship. Since the upgrade the reenatrant error has not appeared. but take a note the mailing list server is not yet LIVE, so the actual test would be when I bring back the mailing list server into production. thanks for reading , tried to keep it short and brief. -regs Harshul ---------------------------------------------------------------- The world is full of willing people; some willing to work, the rest willing to let them. - Robert Frost

Need some suggestions on this topic
by Vidhata Deshpande 11 Aug '03

11 Aug '03

Thanks for the reply, Philip. I am newbie at linux.I did go thru the diald Howto... I just wanted to clear one small glitch. When my eth crd is not detected, the system will give me an output "connect : Network is unreachble" on trying to ping.(ping,say VSNL) In cse I want to divert this commnd to an evaluation n it's value to variable in a script,I will need to 'grep' the output of ping. This I have tried already(grep o/p of ping when the network card is down) The o/p of ping is not fed to grep for comparing patterns, rather, the script just puts up the message of 'Network is unreachable' on the monitor,and goes ahead executing the script. I would like to know,is there any specific way I can catch this output and then grep it to evaluate and set the condition right for the script to detect the eth card is not being detected and perform the necessry software resolving. Thank you Vidhata ___________________________________________________ Meet your old school or college friends from 1 Million + database... Click here to reunite www.batchmates.com/rediff.asp
