This problem is occurring on Red Hat EL 5 WS. However, I have two CentOS 5 systems, with similar configuration to RH EL 5, where this problem does not occur.
I am getting this error:
Can't exec "sendmail": No such file or directory at ./0logwatch line 1018, <TESTFILE> line 1.
Can't execute sendmail -t: No such file or directory
Logwatch has been showing me there is kernal errors present on my server.Below is the full report from logwatch, please let me know if there is anything I should be aware of and fix.

sMsg=0x6974320 "blablabla"...) at MyCls.cpp:270
270 cout<<endl<<"m_FilePtr="<<hex<<m_FilePtr<<dec<<endl;
Basically, Valgrind reported the "Invalid Read" error at line 270 of file MyCls.cpp, which is simply a cout of the m_FilePtr variable, which is a member variable of the MyCls class. It's a FILE* variable I use to write repeatedly on a text file. The address reported (0x47a5ee8) is 296 bytes after the "this" pointer (0x47a5dc0),as Valgrind correctly tells me but I honestly don't understand that. And of course, I need to read that variable, not only for the cout (indeed,the error is reported at every reading attempt). Besides, the application doesn't crash, but still I would like to understand if I really have to worry about this "error".
I am anticipating that someone could give more further information about that, not only simple explanations. How to understand User Time, sys time, wait time, idle time of CPU

i want to make sure my mail server is behaving as expected. the past two nights, i've received logwatch notices below. the section in question is the 20 or so deferrals from some .ru e-mail address. i've since removed the user that registered on my wordpress blog (wlvp@yandex.ru) and added the three IP address to iptables DROP, but these "e-mails" still look like they're in some queue unless i'm reading wrong. i've removed known usernames in case you find the numbers useful. why are all these deferred messages here? if they're stuck in a queue, can i remove them?

View 3 Replies View RelatedMy ISP blocks outgoing email if it does not login properly with a valid account. I successfully configured sendmail to use SMART_HOST and confAUTH_OPTIONS with confAUTH_MECHANISM set to LOGIN PLAIN.
It successfully sends email because I tested it with evolution sending through 127.0.0.1, but I need to specify myacount@mydomain.com as the email address for root.
But it doesn't work for logwatch because it sends as from root@localhost.localdomain, and my ISP's smtp server rejects it. The message I get back in root@localhost account is the following:
----- Transcript of session follows -----
... while talking to smtp.mydomain.com.:
>>> MAIL From:<root@localhost.localdomain> SIZE=581 AUTH=<>
<<< 550 5.7.1 Client does not have permissions to send as this sender
554 5.0.0 Service unavailable
I thought that I should masquerade all emails from this domain, so I configured sendmail as specified in [1] section "24.3.1.4. Masquerading", but it doesn't work. It seems that masquerading in sendmail is broken or something is wrong in the documentation.

I have sendmail 8.13.8-2 and centos-release-5-4.el5.centos.1.
Is there a way to specify the "From:myacount@mydomain.com" in logwatch ? or Is there a way to make it work the masquerading in sendmail so I can masquerade everything as coming from a specific account?
We have following setup,
1. Webserver (Centos 5.5)
2. Mail server (Centos 5.5)
We have configured autossh successfully to create/manage the ssh tunnel into mail server in order to dump all emails to localhost port.
To auto start autossh in boot time we have included following into /etc/rc.d/rc.local,
Quote:
So whenever our web application wants to send out emails it dump all emails to localhost:33465 port, easy piecy, all are working great
Now we have a requirement that logwatch reports should get delivered via the same ssh tunnel rather than installing postfix and configuring as a relay.
In logwatch is there a way to achieve that?
I face "read error " while booting. sometimes it start normally. someone told me to check hard disk for errors. i used gsmartcontrol for this. but from its result i am unable to decide is this hard disk failure or just minor errors. can somebody tell me do i require to change my hd or it just something else to cause such error.

View 3 Replies View RelatedI've installed Logwatch 7.3.6 via the rpm on my CentOS 5.4 server. The issue is I'm getting basically empty reports from logwatch. The only two sections which have any information are samba and diskspace.
The only default options in the config file I've modified are: Code: print = No output = html I'm suspecting the issue has to do with the fact that the as-logged host name doesn't match my current host name. However, I've tried manually changing this on a few entries so they match but they didn't show up in the report. According to the config file, the default for option HostLimit is "No" -- so Logwatch should not care what hostname it sees in a log file, right?
I am receving emails from logwatch but when I setup my own mail script using mutt, the script succeeds but no email is received.Any ideas what the difference is between the two mail methods?

When I installed Cent before I got my logwatch messages sent to me. for somreason this new server I built I am not getting them. can mail off the server and there is no mail in the Q or in root. I also put in a .forward file in my root to mail to my external account and it works fine. I get mail from fail2ban and denyhosts but not the logwatch.Thoughts on what I could be missing? I check the link and the files are all there. I changed the config file to give me a High level of detail. Thats about it. If I use the command line for logwatch it sends mail fine. logwatch --detail high --logfile messages --mailto yourname@domain.com

View 1 Replies View RelatedIn the beginning there is MBR. MBR looks for the active partition and tranfers control to the VBR of the active partition. MBR is where grub may be installed. which allows the user to choose an OS(a VBR) I am not sure what the program in the VBR does,but it manages to loads the OS. What am I trying to do: Backup. I ma tired of losign my partitions my bootloaders. I want to backup them all! partitions/MBR /VBR everything short of creating an disk image.
My questions:
1. say the ubuntu partition is formatted, will grub still load? if not is there a bootloader that would?am I making sense? i hope so...
2. what exactly does the VBR contain ?
2. How do I go about backing up? The mbr and the partiton table are backed up with a simple dd command. Then what else needs to be backed ? VBR's of every partition?

Well I get my other 2 questions answered , I have one last question that has been buggy me.Anyone know why windows use so many files just to keep the OS going and so bloated? The under line of files of windows is messy and loads self every where and very bloated with windows and windows vista and windows 7 very much so.I'm not sure if Linux /Mac OS X is like this or not .
I know windows needs to support alot more software and hardwar but is that not where drivers come in for the hardware.And programmers need to write the software for windows or Linux / Mac OS X.
